2 · THE GEA WAY TO PERFECT KARAAGEWHAT IS KARAAGE?Karaage is a traditional Asian cooking technique, dating backto the 17th Century, in which choice cuts of meat (usually chicken), fishor vegetables are fried in a light oil with a corn or potato starch coating. The coatingcan be seasoned flour (dry Karaage) or a light, crispy batter (wet Karaage).The method became popular in the 1940s and 50s as a simple, nutritious way of cooking. Today it is found throughout the region in restaurants, as easy street food, and, of course, in the home. There are many variations of Karaage with each area, and even individual restaurants, creating their own unique style.Fully automated Karaage - even better than home madeDefrosting GEA ColdSteam T Wet coatingGEATempuDipperHomestylecoatingGEAFryingGEA EasyFryCookingGEA CookStarFreezingGEACALLIFREEZE 456784 · THE GEA WAY TO PERFECT KARAAGEGEA BRINE INJECTION, FORBONE-IN & SKIN-ON PRODUCTSWould you like to process bone-in or skin-on Karaageproducts without skin slip, damaged bones, brine pockets orvisible needle holes?

MuzzioDepartment of Chemical and Biochemical Engineering, Rutgers University, Piscataway, NJ, 08855, United StatesReceived 17 February 2009;revised 30 May 2009;accepted 14 June 2009.Available online 27 June 2009.AbstractThe dynamics involved in powder mixing remains a topic of interest for many researchers; however the theory still remains underdeveloped. Most of the mixers are still designed and scaled up on empirical basis. In many industries, including pharmaceutical, the majority of blending is performed using ―tumbling mixers‖. Tumbling mixers are hollow containers which are partially loaded with materials and rotated for some number of revolutions. Some common examples include horizontal drum mixers, v- blenders, double cone blenders and bin blenders. In all these mixers while homogenization in the direction of rotation is fast, mediated by a convective mixing process, mixing in the horizontal (axial) direction, driven by a dispersive process, is often much slower. In this paper, we experimentally investigate a new tumbling mixer that rotates with respect to two axes: a horizontal axis (tumbling motion), and a central symmetry axis (spinning motion). A detailed study is conducted on mixing performance of powders and the effect of critical fundamental parameters including blender geometry, speed, fill level, presence of baffles, loading pattern, and axis of rotation. In this work Acetaminophen is used as the active pharmaceutical ingredient and the formulation contains commonly used excipients such as Avicel and Lactose. The mixing efficiency is characterized by extracting samples after pre-determined number of revolutions, and analyzing them using Near Infrared Spectroscopy to determine compositionaldistribution. Results show the importance of process variables including the axis of rotation on homogeneity of powder blends.

IntroductionParticle blending is a required step in a variety of applications spanning the ceramic, food, glass, metallurgical, polymers, and pharmaceuticals industries. Despite the long history of dry solids mixing (or perhaps because of it), comparatively little is known of the mechanisms involved [1], [2] and [3]. A common type of batch industrial mixer is the tumbling blender, where grains flow by a combination of gravity and vessel rotation. Although the tumbling blender is a very common device, mixing and segregation mechanisms in these devices are not fully understood and the design of blending equipment is largely based on empirical methods. Tumblers are the most common batch mixers in industry, and also find use in myriad of application as dryers, kilns, coaters, mills and granulators [4], [5], [6], [7] and [8]. While free-flowing materials in rotating drums have been extensively studied [9] and [10], cohesive granular flows in these systems are still not completely understood. Little is known about the effect of fundamental parameters such as blender geometry, speed, fill level, presence of baffles, loading pattern and axis of rotation on mixing performance of cohesive powders or the scaling requirements of the devices.However, conventional tumblers, rotating around a horizontal axis, all share an important characteristic: while homogenization in the direction of rotation is fast, mediated by a convective mixing process, mixing in the horizontal (axial) direction, driven by a dispersive process, is often much slower.In this paper, we experimentally investigate a new tumbling mixer that rotates with respect to two axes: a horizontal axis (tumbling motion), and a central symmetry axis (spinning motion). We examine the effects of fill level, mixing time, loading pattern and axis of rotation on the mixing performance of a free-flowing matrix of Fast Flo lactose and Avicel 102, containing a moderately cohesive API, micronized Acetaminophen. We use extensive sampling to characterize mixing by tracking the evolution of Acetaminophen homogeneity using a Near Infrared spectroscopy detection method. After materials and methods are described in Section 2, results are presented in Section 3, followed by conclusions and recommendations, which are presented in Section 4.2. Materials and methodsThe materials used in the study are listed in Table 1, along with their size and morphology. Acetaminophen is blended with commonly used excipients and is used as a tracer to evaluate the degree of homogeneity achieved as a function of number of revolutions. Acetaminophen is one of the drugs most widely used in mixing studies, and Avicel and Lactose are commonly used pharmaceutical excipients. In the interest of brevity their SEM images are not included in this paper, but can be found in ―Handbook of Pharmaceutical excipients‖.2.1. Near infrared spectroscopyAcetaminophen homogeneity was quantified using near infrared spectroscopy. A calibration curve was constructed for a powder mixture containing (in average) 35% avicel PH 102, 62% lactose and 3% acetaminophen. Near infrared (NIR) spectroscopy can be a useful tool to characterize acetaminophen. Samples are prepared by keeping the ratio of Avicel to lactose randomized in order to minimize effects of imperfect blending of excipients during the actual experiments on the accuracy of the results. The Rapid Content Analyzer instrument manufactured by FOSS NIR Systems (Silver Spring, MD) and Vision software (version 2.1) is used for the analysis. The samples are prepared by weighing 1 g of mixture into separate optical scintillation vials; (Kimble Glass Inc. Vineland, NJ) using a balance with an accuracy of ± 0.01 mg. Near-IR spectra are collected by scanning in the range 1116–2482 nm in the reflectance mode. Partial least square (PLS) regression is used in calibration model development using the second derivative mathematical pretreatment to minimize the particle size effects. As shown in Fig. 1, excellent agreement is achieved between the calibrated and predicted values.Fig. 1.Fig. 1. Near Infrared (NIR) spectroscopy validation curve. The equation used to predict acetaminophen concentration is validated by testing samples with known amounts of acetaminophen concentration. The y axis represents the concentration calculated from the equation and the x axis represents the actual concentration. Thus a perfectly straight line at 45°would represent the best calibration model. Each point on the graph represents a single sample. The concentration of acetaminophen examined here ranges from 0 to 8%.2.2. Bin blenders used in this study: uni-axial blender (Blender 1), bi-axial blender (Blender 2)Due to its widespread use, a cylindrical blender 1 with a capacity of 30 L is chosen as a reference blender in the study. As shown in Fig. 2, this blender has a circular cross section and tapers at the bottom. It can be used with or without baffles, which are mounted on a removable lid. In this study all the experiments are conducted without the use of baffles. Mixing performance in this device is used to provide a base-line for evaluating the mixing performance of a newly developed blender 2 with a capacity of 40 L, which is also cylindrical, in order to determine the effect of dual axis of rotation on mixing performance. The blender shown in Fig. 2(b) has two axis of rotation. The spinning rate of precession relative to the central axis of symmetry is geared to be half of that of the rate of rotation around the horizontal axis.Fig. 2.Fig. 2. Pictorial representation of (a) bin blender 1 and (b) bin blender 2 showing the corresponding axis of rotation.2.3. Experimental methodTwo types of initial powder loading used in the experiments: top–bottom loading and side–loading, which are schematically represented in Fig. 3. To avoid agglomeration, the API, acetaminophen, was delumped prior to loading it into the blender by passing it through a 35 mesh screen. In order to characterize mixing performance, a groove sampler was used to extract samples from the blenders at 7.5, 15, 30, 60, 120 revolutions. The thief was carefully inserted in the bin, and a core was extracted at each point of insertion (each ―stab‖) minimizing perturbation to the powder bed remaining in the blender. Approximately 7 samples are taken from each thief stab, and a total of five stabs are used at each sampling time, as shown in Fig. 4 so a total of 35 samples are taken at each sampling point.Fig. 3.Fig. 3. Schematic of the loading pattern used in the study. In top–bottom loading, Avicel is loaded first into the blender followed by Lactose on top of it and finally Acetaminophen is uniformly sieved over. In side–side loading avicel is placed at the bottom and then Acetaminophen is only sieved only in half part of the blender and is sandwiched between lactose and Avicel.Fig. 4.Fig. 4. (a) Thief sampler (b) top view of the sampling position scheme. The experimental plan used in this study is as follows:•Fill level: blender 1–60%•Fill level: blender 2–60%, 70%, 80%•Loading pattern: blender 1 —side–side loading, top–bottom loading•Loading pattern: blender 2 —side–side loading, top–bottom loading•Speed: blender 1–15 rpm, 20 rpm, 25 rpm•Speed: blender 2 —rotational/spinning:15/7.5 rpm, 20/10 rpm, 30/15 rpm•Sampling time: blender 1, blender 2–7.5, 15, 30, 60, 120 revolutions3. ResultsThe homogeneity index used is the RSD, where C is the concentration of each individual sample, C_is the average concentration of all samples and n is the total number of samples obtained at a given sampling time.We examine the effect of fill level on mixing performance. Previously there have been studies on the effect of fill level in the Bohle bin blender, Gallay bin blender and V- blender and double cone blender [11], [12] and [13]. All the aforementioned blenders have only one axis of rotation, therefore the objective of this study is to examine how dual axis impact mixing performances at high fill levels. To avoid repetition, studies for fill level are not conducted for bin blender 1. Results available from a previous study using MgSt as a tracer showed that mixing in a uni-axial blender slowed down quite dramatically as the fill level exceeded 70%. Moreover, results for acetaminophen can be assumed to be similar to those obtained in previous work by Muzzio et al. [11] and [13], for a single axis rectangular bin blender [11], which have shown that even after few hundred revolutions homogeneity achieved with a 80% fill level is very poor as compared to 60% fill level.To examine the effect of fill level in a dual axis blender, experiments were performed in blender 2 with the top-bottom loading pattern for a rotational speed of 15 rpm and with spinning speed of 7.5 rpm. The fill levels examined are 60%, 70% and 80%respectively and samples are taken after 7.5, 15, 30, 60, 120 revolutions. Typical results are shown in Fig. 5, which shows the RSD vs. number of blender revolutions. As expected for non-agglomerating materials, the curves show a rapidly decaying region. The slope of the curves in this region, in semi-logarithmic coordinates, is used to define the mixing rate. The curves then level off to a plateau that indicates the maximum degree of homogeneity that is achievable in the blender for a give material.Fig. 5.Fig. 5. Mixing curves for different fill levels in blender 2. The RSD of acetaminophen is plotted as a function of number of revolutions. The loading pattern in top-bottom and the blender rotational speed is 15 rpm with spinning speed of 7.5 rpm.Similar to previous studies with other tumbling blenders we observe that blending performance is adversely affected by increasing fill levels. As shown in Fig. 5, the curve for 80% fill performs more poorly than those for 60% and 70% fill; as fill level increases, RSD curves decay more slowly, signifying a slower mixing process. However, the effect is not as pronounced as in other bin blenders and after about only 100 revolutions, the same plateau (the same asymptotic blend homogeneity) is achieved for all three fill levels.Next, the effect of rotational speed is investigated in the blender 1 with one axis of rotation and is compared to the blender 2 with dual rotation axis. Experiments were conducted for both blenders with top-bottom and side-side loading. Experiments were performed at 60% fill level and the rotation speeds considered for blender 1 are 15 rpm, 20 rpm and 25 rpm respectively. As shown in Fig. 6 and Fig. 7, when plotted as a function of blender revolutions, there is notmuch of an effect of rotation speed on the homogeneity index (RSD) of acetaminophen at 60% fill level. It is observed that mixing performance at 20 rpm and 25 rpm is slightly better than at 15 rpm, however the differences in the performance of the blender under different speeds are probably too small to be significant. RSD curves decay with the same slope, indicating similar mixing rates. In the study reported here, the fill level is only 60%, and all the rotational speeds are enough to achieve homogenization. The aforementioned studies were conducted at 85% fill level. For such a high fill level, at low speeds, a stagnant core is known to occur at the center of many blenders, requiring higher shear stress per unit volume to achieve homogenization. Moreover, the flow properties of MgSt are known to be strongly different than those of most materials, and are known to have a deep impact on the flow properties of the mixture as a whole. Furthermore, MgSt is famously known to be a shear sensitive material. Thus an expectation that lubricated and unlubricated blends would show similar behavior with respect to shear is probably unwarranted.Fig. 6.Fig. 6. Mixing curves for top-bottom loading experiments with 60% fill level. RSD is plotted as a function of number of revolutions. Dotted lines correspond to experiments in the blender 1, while solid lines represent data points from the blender 2.Fig. 7.Fig. 7. curves for side–side loading experiments with 60% fill level. RSD is plotted as a function of number of revolutions. Dotted lines correspond to experiments in the while solid lines represent data points from the 2.Subsequently, experiments were performed using the blender 2 at three rotation speeds: 15 rpm, 20 rpm and 30 rpm, and as explained before, the corresponding spinning speeds were 7.5 rpm, 10 rpm and 15 rpm. Fill level considered for both side-side and top-bottom loading was 60%.Again, it was observed that varying rotation and spinning speeds did not make much difference in mixing rate. As shown in Fig. 6 and Fig. 7, mixing curves for blender 2 vary only slightly with rotation speed. For the top-bottom loading pattern it appears that mixing improves slightly when rotation speed is increased (the plateau is slightly lower for higher rotation speeds, indicating an improvement in the levels of asymptotic homogeneity), but no significant changes with speed are observed in side-side loading pattern.The blending performance of both blenders is compared at different rotation speeds for both side-side and top-bottom loading patterns. To make a fair comparison, the fill level was kept as 60% for both blenders, a condition for which both blenders achieve effective mixing at long enough times. Due to geometric similarity of the two blenders, this comparison help evaluate the effect of spin (rotation with respect to the central symmetry axis) on mixing performance. As shown in Fig. 6, the mixing curves for the blender 2 lie below those for the blender 1 for each rotation rate, indicating faster mixing. Note that the final RSD asymptotereached for both blenders is also different, with the blender 2 showing a lower asymptote (better final mixed state, presumably due to a lesser effect of the slow mixing mode in the horizontal direction) than blender 1.Similar results were obtained for the side-side loading pattern, as displayed in Fig. 7. The RSD curves for the blender 1 for all the three rotation rates lie above the blender 2. It is therefore confirmed that spinning a blender in direction perpendicular to the rotation axis helps in enhancing mixture homogeneity; however, for the materials examined here, the rotation rate does not have much effect on mixing performance.Finally, a comparison is made between the two loading patterns for both blenders. Again, to achieve a fair comparison, all experiments are performed at 15 rpm and 60% fill level. As evident in Fig. 8, in both blenders top–bottom loading gives a more rapid decay of the RSD, indicating faster homogenization as compared to side–side loading pattern. However, for both loading modes, blender 2 achieves faster homogenization.Fig. 8.Fig. 8. Comparison between the mixing curves of the blender 2 and the blender 1 for top–bottom and side–side loading pattern. Dotted lines correspond to experiments in the blender 1, while solid lines represent data points from the blender 2. Experiments are performed at 15 rpm with 60% fill level.As reported in previous studies, all the RSD curves in this paper exhibit a common trend with respect to time, characterized by an initial period of rapid homogenization due to convective mixing, followed by a period of much slower homogenization typically controlled by dispersion or shear. This trend is shown schematically in Fig. 9. The first regime is a fast exponential decay and the second oneis a slow exponential asymptote to a limiting plateau. The first part represents a rapid reduction in heterogeneity driven by the bulk flow (convection); the slope of the RSD curve, in semi-logarithmiccoordinates, is the convective mixing rate. The second part is driven by individual particle motion (dispersion) or by the slowerosion of API agglomerates due to shear.Fig. 9.Fig. 9. A typical mixing plot, with RSD plotted against number of revolutions. The two solid lines emphasize on the two distinctive mixing regimes.When only one mixing mechanism is present (a situation that can be achieved by careful control of the initial loading pattern), a simple mass-transfer model, represented in Eq. (1) can be used, as in past studies [14], to capture the evolution of the RSD in powder systems. In this model, an exponential curve decaying towards a plateau is fitted to the mixing curves, where σis the standard deviation, σ∞the final standard deviation, A is an integration constant, λsignifies the mixing rate constant, and N is the number of revolutions. This model predicts that the experimental variance will decay exponentially with time as it approaches the random mixture state. In order to characterize numerically the ― mixing rate,‖ λ has to be computed for each blending experiment.)σ−σ∞=Ae−λNThe values for parameters A and λare calculated by minimizing the sum of squares of errors between the data and an exponential function. The value of final standard deviation (σ∞) is taken as the lowest value of the variance achieved in the mixing studies. The values for λ are computed for blending experiments with different percentage fill, and loading pattern and the results are plotted in Fig. 10 and Fig.11. As shown in Fig. 10, the mixing rate constant decreases withincrease in percentage fill level. A broader comparison with two other bin blenders is provided in Fig. 11, which displays the mixing rate for the blender 2, for the blender 1 with and without baffles, and for a commercially available rectangular blender. The figure also illustrates the effect of loading pattern on these four bin blenders, all of them rotated at 20 rpm. It is evident that blender 2 with dual axis of rotation has the highest mixing rate constant of the entire group. For all blenders used in this study, there is also an effect of loading pattern on mixing; it was found that top–bottom loading pattern gives better mixing performance than side-side loading.Fig. 10Fig. 10. Mixing performance was evaluated at three different fill levels for blender 2. Experiments were performed at 60%, 70% and 80% fill levels at 15 rpm with top–bottom loading. Mixing rate constant (λ) values is plotted as a function of fill level and found to increase with decrease in fill level.Fig. 11Fig. 11. Mixing performance of bin blenders along with loading pattern are compared at 20 rpm with 60% fill level. Mixing rate constant (λ) values plotted for different loading patterns in bin blenders with and without baffle and as shown above, blender 2givers a better mixing performance as compared to blender 1. There is also a pronounced effect of loading pattern, and regardless of the blender used, top–bottom loading always gives a better performance compared to side–side.4. ConclusionThe effects of fill level, mixing time, loading pattern and axis of rotation on the mixing performance of a free-flowing matrix of Fast Flo lactose and Avicel 102, containing a moderately cohesive API, micronized Acetaminophen was examined. Blending performance was found to be adversely affected at increasing fill levels. Top–bottom loading pattern was shown to lead to better mixing performance than side-side loading pattern. It was also confirmed that spinning a blender in direction perpendicular to the rotation axis helps in enhancing mixture homogeneity. A mathematical mixing model was utilized to compare mixing rates at different fill levels, blender types and loading pattern. It was shown that mixing rates were enhanced at low fill levels, top-bottom loading patterns, and for blender with dual axis of rotation.References[1] B.H. Kaye, Powder Mixing: Chapman & Hall.[2] K.

Always switch amplifier power on last in line with volume levels down.Using good quality 6.3mm jack or XLR leads (balanced or unbalanced), connect L + R main outputs from the mixer to the amplifier, recorder or whichever equipment is to receive the main mix output. If pha ntom power is to be used, press the “+48V PHANTOM” switch in. Connect microphones, DI boxes and other balanced low impedance audio inputs to the mono channels using a quality XLR lead.Connect high impedance and line level signals to the mono inputs using a 6.3mm jack lead. For the stereo channel, connect left and right line level signals via 6.3mm jack or RCA leads (unbalanced). If this channel is to be used as mono, connect to the left jack input only. Channel inserts may be connected to individual processing equipment like EQ or compressors. These connections completely interrupt the signal flow and divert to the external processor before returning to the channel for volume adjustment via the channel fader. This requires a stereo to 2 x mono jack lead – the 2 mono ends are send and return connections, the stereo connection is wired as per below.Recording equipment can be connected via the “REC” outputs using a twin RCA lead and the6.3mm jack AUX output can be connected to monitoring or external processing equipment if required. Individual levels can be adjusted to the AUX output via the individual channel AUXcontrols. Overall auxiliary send level is governed by the master AUX control.If the internal DSP effects are not required, a send can be co nnected from the “EFFECT” jack output to and external effect unit, whereby the EFF channel controls act as individual level controls to the EFFECT output (same as for AUX output) Overall effect send level is governed by the master EFFECT level control.With all faders down, connect the supplied AC adapter to the 12Vac input and to the mains supply (ensure correct supply voltage) – the power LED will illuminate (if phantom power is selected, this LED should light also)CheckingTest each channel’s gain l evel by making the loudest expected sound into it and increasing the GAIN control until the red PEAK LED starts to light. Then back the GAIN control off slightly until the PEAK LED hardly lights at all.Test the main mix output by increasing the MAIN master fader and selected channel faders whilst making sound through the channel(s) – the L + R output LED ladders should begin to show the output as it varies up and down.Connecting a pair of headphones to the PHONES stereo 6.3mm jack is a good way of checking the mix output, remembering to gradually increase the PHONES level control.Turn down all faders and then switch power on to connected equipment (amplifier last in line) and increase volume levels. Gradually increase MAIN and channel faders again and the sound should be heard through the speakers or be indicated on the recording equipment.OperationMono channels have a COMP control which varies the amount of audio compression applied to the signal. Fully down (anti-clockwise) gives no compression and fully up (clockwise) gives maximum compression to the signal, making quieter sounds louder and louder sounds quieter whilst boosting the signal. This limits the dynamic differences in a signal and is especially useful for vocals and some instruments where the sound level can vary greatly.Each channel has a 3-band EQ (LOW/MID/HIGH), which can be used to balance the mix of frequencies and emphasise certain aural characteristics in the signal. Adjust these as required, noting that and overall increase may require an equivalent reduction of the GAIN control to compensate (otherwise clipping may occur from EQ boost).Use the PAN control to position the channel input either to the left or right side of the stereo field. This can be useful to help separate and define sounds within a mix but be aware that extreme settings can be counter-productive by removing the channel from certain listening positions.Use the AUX control to feed the correct amount of the channel signal to the AUX output. This routing is “Pr e-fader” and is independent from the channel fader setting.The EFF control feeds a part of the signal to the internal DSP effects. Overall controls for TIME and LEVEL are on the right-hand side of the control surface - these can be adjusted as required.If external effects are to be used, plugging a jack lead into the EFFECT output defeats the internal DSP effects and acts as a mono line level “send” to the external effect unit. Theoutput(s) from the external unit will need to be “returned” via a mono or stereo channel and added to the mix, whereby the channel fader takes the place of the overall EFFECT return level control.Channel faders should be used to adjust the individual levels in the mix and the MAIN fader is for overall level. Turn down amplifier levels when changing any connections or powering down the mixer to avoid speaker damage.USB featuresThe USB and SD card connection is for the internal media player, which can offer playback of compressed digital audio files through the stereo channel.When a USB pen drive or SD card with such files on is connected via the rear panel, the player recognizes this and automatically begins playback through the stereo channel.Transport buttons are situated next to the output LEDs on the top panel to control USB/SD playback as shown below …SpecificationsDSP effect programmesTroubleshootingErrors and omissions excepted.Copyright© 2012.

prevents the cement mortar to agglomerate on mixing shaft, the shaft terminal seal
uses the multiple seal structure, effectively prevents mortar divulging and guarantees
the entire mixing system continuing to word for a long time.
4. The flushing system uses the high-pressured water pump with hand-control, all
exhalant pores are located above the main mixing shaft. Enhances the mixing
efficiency, increased the mist, reduces the dust-pollution and effectively eliminates the
cement agglomerated.
5. The mixing blade uses the unique high-hardness, the tough-antifriction metal
material, enhances the reliable performance of the main engine enormously.
