1引言1.1苹果概述苹果,别名频婆。
原产于欧洲中部和东南部、中亚细亚以及我国新疆一带。
在欧洲,苹果是最古老的果树之一,早在公元前2000以前就已人工栽培。
在哥伦布发现新大陆之后,欧洲的移民把苹果传到了美国。
在东方,日本在明治维新时代引进苹果栽培技术。
此后,苹果又相继传入了欧洲、澳洲、非洲。
从18世纪以来,人们不断的改进苹果的品种以追求更好的品质。
在我国,根据晋代郭义恭的《广志》以及后魏贾思勰的《齐民要术》记载,苹果在我国已经有2000多年的栽培历史。
目前,在我国各个苹果产区作为经济作物栽培的苹果品种还几乎都是从国外引进的,统称为西洋苹果。
我国开始引进西洋苹果是在1870年,栽培历史仅100年左右[1]。
1.2苹果汁的历史,现状和发展趋势苹果汁的加工距今已有一百多年的历史。
大规模的工业化生产约在1930年,始于欧洲和美国,北美的苹果汁工业化生产大约始于1937年。
我国的苹果汁生产近年已初具规模,国内不少企业从意大利、德国、瑞典和美国引进现代化的苹果汁生产线,也有许多企业采用国产化苹果汁生产线。
国产化苹果汁生产线采用了先进的生产工艺,所用设备全部选用国产设备,大幅度降低了投资成本,配件供应及时,设备维修方便,费用低[2]。
由于近年来随着经济的发展,果汁逐渐取代碳酸型的饮料成为了人们日常的饮品,苹果汁作为产量较大的果汁品种,有很大的发展前景。
另外目前我国苹果鲜销市场已出现卖苹果难的问题,发展苹果加工业是解决卖果难的一条重要途径。
苹果可以加工成许多产品,但以果汁最受欢迎。
市场上销售的苹果汁主要以清汁为主,而且大都是由浓缩汁加水还原而成。
在苹果清汁或浓缩汁生产中,澄清过程都需添加果胶酶分解果汁中的果胶及添加一些澄清剂如明胶,不仅生产工艺复杂,而且延长了加工时间,如处理不当会影响产品的风味,营养成分被破坏,同时苹果中的果胶作为一种膳食纤维没有被利用。
随着消费者健康意识的增强,纯天然、营养、新鲜、保持水果原味的浑浊型果汁为消费者崇尚。

英文文献2.5.3. Design and construction of the buildingRoofs and ceilingsWallsWindows and doorsFloorsLighting and powerWater supply and sanitationLayout of equipment and facilitiesIn general, a building should have enough space for all production processes to take place without congestion and for storage of raw materials, packaging materials and finished products. However, the investment should be appropriate to the size and expected profitability of the enterprise to reduce start-up capital, the size of any loans taken out and depreciation and maintenance charges.Roofs and ceilingsIn tropical climates, overhanging roofs keep direct sunlight off the walls and out of the building. This is particularly important when processing involves heating, to make working conditions more comfortable. Fiber-cement tiles offer greater insulation against heat from the sun than galvanized iron sheets do. High level vents in roofs both allow heat and steam to escape and encourage a flow of fresh air through the processing room. The vents must be screened with mesh to prevent insects, rodents and birds from entering the room. If heat is a serious problem, the entrepreneur could consider fitting electric fans or extractors, although this clearly increases capital and operating costs.Rafters or roof beams within the processing and storage rooms are unacceptable. They allow dust to accumulate, which can fall off in lumps to cause gross contamination of products. Similarly, insects can fall from them into products. They also allow paths for rodents and birds, with consequent risks of contamination from hairs, feathers or excreta. It is therefore essential to have a paneled ceiling fitted to any processing or store-oom, with careful attention when fitting them to ensure that there are no holes in the paneling. Care should also be taken to prevent birds, rodents and flying insects gaining access to the processing room through gaps in the roof structure or where the roof joins the walls.WallsAs a minimum requirement, all internal walls should be rendered or plastered with a good quality plaster to prevent dust forming in the processing room. An experienced plasterer should be used to ensure that no cracks or ledges remain in the surface finish, which could accumulate dirt and insects. The lower area of walls, to at least 1.08 metres (four feet) above the floor, is most likely to get dirty from washing equipment, from product splashing etc. and special attention should be paid to ensure that this area is easily cleaned. Higher areas of walls should be painted with a good quality emulsion. The lower parts of walls should be either painted with a waterproof gloss paint, preferably white, to allow them to be thoroughly cleaned, or ideally they should be tiled with glazed tiles. If tiling a process room is too expensive, it is possible to select particular areas such as behind sinks or machinery and only tile these parts. In some countries there is a legal requirement for specified internal finishes and this should be checked with the Ministry of Health or other appropriate authority (see also Section 2.4.2)Windows and doorsWindow sills should be made to slope for two reasons: to prevent dust from accumulating and to prevent operators from leaving cloths or other items lying there, which in turn can attract insects. Windows allow staff to work in natural daylight, which is preferable to and cheaper than electric lighting. However, in tropical climates there is a natural inclination for workers to open windows to allow greater circulation of fresh air. This provides easy access for flying insects, which can readily contaminate the product. Windows should therefore be fitted with mosquito mesh to allow them to be left open.Normally doors should be kept closed, but if they are used regularly there is again a tendency for them to be left open with similar consequences of animals and insects entering the plant. In this case, thin metal chains or strips of material that are hung vertically from the door lintel may deter insects and some animals, while allowing easy access for staff. Alternatively mesh door screens can be used. Doors should be fitted accurately so that there are no gaps beneath them and all storeroom doors should be kept closed to prevent insects and rodents from destroying stock or ingredients.FloorsIt is essential to ensure that the floors of processing rooms and storerooms are constructed of good quality concrete, smooth finished and without cracks. In some developing countries, it is possible to buy proprietary floor paints or vinyl based coatings, but these are usually very expensive. Generally, it is not adequate to use the red wax floor polishes that are commonly found in households, as these wear away easily and could contaminate either products or packages. Over time, spillages of acidic fruit products react with concrete andcause it to erode. Attention should therefore be paid to cleaning up spillages as they occur and to regularly monitor the condition of the floor.The comers where the floor and the walls join are places for dirt to collect. During construction of the floor, it should therefore be curved up to meet the wall. It is possible to place fillets of concrete (or 'coving') in the comers of an existing floor to fill up the right angle, but care is needed to ensure that new gaps are not created which would harbour dirt and insects.The floor should slope at an angle of approximately 1 in 8 to a central drainage channel. At the end of a day's production, the floor can be thoroughly washed and drained. Proper drainage prevents pools of stagnant water forming, which would in turn risk contamination of equipment and foods. The drainage channel should be fitted with an easily removed steel grating so that the drain can be cleaned. Where the drain exits the building, there is a potential entry point for rodents and crawling insects unless wire mesh is fitted over the drain opening. This too should be easily removed for cleaning.Lighting and powerGeneral room lighting should be minimized wherever possible. Full use should be made of natural daylight, which is both free and better quality light, especially for intricate work. Where additional lighting is needed, florescent tubes are cheaper to operate than incandescent bulbs. However, if machinery is used that has fast moving exposed parts, these should be lit with incandescent bulbs and not tubes. This is because even though the parts should have guards fitted, a rotating machine can appear to stand still if its speed matches the number of cycles of the mains electricity that powers fluorescent tubes - with obvious dangers to operators.All electric power points should be placed at a sufficiently high level above the floor that there is no risk of water entering them during washing the floor or equipment. Ideally, waterproof sockets should be used. It is important to use each power point for one application and not use multiple sockets which risk overloading a circuit and causing a fire. If there are insufficient power points for the needs of a process, additional points should be installed, even though this is more expensive. All plugs should be fitted with fuses that are appropriate for the power rating of the equipment and ideally the mains supply should have an earth leakage trip switch. If three-phase power is needed for larger machines or for heavy loads from electric heating, it is important that the wiring is installed by a qualified electrician to balance the supply across the three phases.Water supply and sanitationWater is essential in nearly all fruit and vegetable processing, both as a component of products and for cleaning. An adequate supply of potable water should therefore be available from taps around the processing area. In many countries, the mains supply is unreliable or periodically contaminated and it is therefore necessary for the entrepreneur to make arrangements to secure a regular supply of good quality water each day. This can be done byinstalling two high level, covered storage tanks either in the roof-space or on pillars outside the building. They can be filled alternately when mains water is available and while one tank is being used, any sediment in water in the other tank is settling out. As sedimentation takes several hours, the capacity of each tank should be sufficient for one day's production. The tanks should have a sloping base and be fitted with drain valves above the slope and at the lowest point. In use, water is taken from the upper valve and when the tank is almost empty, the lower valve is opened to flush out any sediment that has accumulated.Water that is included in a product should be carefully treated to remove all traces of sediment and if necessary, it should be sterilised. This is particularly important if the product is not heated after water has been mixed in as an ingredient.There are four ways of treating water at a small scale: by filtration; by heating; byultra-violet light and by chemical sterilants, such as hypochlorite (also named 'chlorine solution' or 'bleach'). Other water treatment methods are generally too expensive at a small scale of operation.Filtration through domestic water filters is slow, but having made the capital expenditure, it is relatively cheap. Larger industrial filters are available in some countries. Heating water to boiling and holding it at that temperature for 10-15 minutes is simple and has low capital costs, but it is expensive because of fuel costs and it is time consuming to do routinely. Heating sterilises the water but does not remove sediment and boiled water may therefore require filtering or standing to remove sediment.Ultra-violet light destroys micro-organisms in water and commercial water treatment units that use this principle (Figure 38) are coming down in price to the point that they can be suitable for those small scale processors that use a lot of water. Again, this method does not remove sediment from the water.Finally, chemical sterilisation using hypochlorite is fast, relatively cheap and effective against a wide range of micro-organisms. Cleaning water should contain about 200 ppm of chorine and water that is used as an ingredient should contain about 0.5 ppm to avoid giving a chlorine flavour to the product. A chlorine concentration of 200 ppm can be made by adding 1 litre of bleach to 250 litres of water and a 0.5 ppm solution is obtained by adding 2.5 ml of bleach to 250 litres of water. Although chlorine kills most micro-organisms, it also has a number of disadvantages: it can corrode aluminium equipment; it can taint foods; bleach must be handled with great care as it damages the necessary, the concentration of chlorine in water can be measured using a chemical dye that produces a colour when it reacts with chlorine. The intensity of the colour is compared to standard colours on glass discs in a 'comparator'.Good sanitation is essential to reduce the risk of product contamination and to deter insects, rodent and birds. All wastes should be placed in bins and not piled on the floor. Processes should have a management system in place to remove wastes from the building as they are produced, rather than letting them accumulate during the day. Wastes should never be left in a processing room overnight. This aspect is described further in Section 2.7.2, and summarized in Appendix I.Layout of equipment and facilitiesThe different areas required for fruit and vegetable processing are shown in Figure 39 for a drying unit and in Figure 40 for other types of production. The layouts of these processing rooms show how raw materials move through a process and through the room without paths crossing. Different stages in a process should be physically separated wherever possible. This helps prevent contamination of finished products by incoming, often dirty, raw materials and clearly identifies areas of the room where special attention to hygiene is necessary. This is particularly important to prevent contamination arising from activities such as bottle washing in which inevitable breakages produce glass splinters that could contaminate a product. This separation also reduces the likelihood of accidents or of operators bumping into each other.Perishable raw materials should be stored separately from non-perishable ingredientsand packaging materials. A separate office allows records to be filed and kept clean and provides a quieter working environment for book-keeping. Toilets should either be housed in a separate building or two doors should exist between them and a processing area. All workers should have access to hand-washing facilities with soap and clean towels. Laboratory facilities are generally not needed in fruit and vegetable processing, although a separate table for conducting quality assurance checks or check-weighing packages of finished product (Section 2.7.2) could be located in the office or in a separate area of the processing room.英文文献译文2.5.3.建筑物的设计和建造屋顶和天花板墙壁窗户和门地板照明和能源水供应和公共卫生仪器和设备的布局总的说来,一个厂房应该有足够的空间来进行产品的加工制造,避免拥堵和原料,包装材料和成品混杂储存的情况发生。

随着科学研究的不断深入,人们对苹果汁的认识较以往更加全面深刻,其保健作用主要表现在以下几方面:①苹果汁中的生物活性物质研究表明苹果汁中的黄酮类化合物与多酚化合物结合在一起具有抗癌的作用,该混合物能抑制人体内癌细胞的生长与扩散,从而起到了一定的抗癌作用。
最近,美国的临床实验表明苹果及苹果汁可以预防心脏病,苹果汁可以降低呼吸系统疾病的作用已有大量科学研究已证实,苹果汁中的某些成分可以改善呼吸系统的功能。
经常食用苹果汁的人与不食用或很少食用苹果汁的人相比,气喘病的发病可能性降低22%~23%,肺癌的发病率可能降低58%。
②苹果汁对人类健康的益处苹果汁不仅可以止渴,而且风味极佳、可以提供丰富的营养物质,对儿童生长发育无任何副作用,其中维生素C有利于铁离子的吸收,苹果是水果中的“主粮”,尽管今年来水果市场繁荣,各种洋水果、热带水果色彩缤纷,但苹果仍然是我国食用最多的果品。
浓缩苹果汁的营养成分表3.市场状况由于中国特有的资源优势为基础,浓缩苹果汁近年来发展迅速,生产规模快速扩张,生产能力也有猛增。
我国的人口众多,随着生活水平的提高,我国对浓缩苹果汁的需求也处在上升的趋势,由于我国人口主要集中在东南部,所以将浓缩苹果汁的市场主要放在我国南方,苹果汁具有很多的功能,可以作为生产苹果汁饮料的原料,可以用来加工酿制苹果酒,可以作为其它各种饮料的补充物,还可以作为食品工业的基础配料,由于浓缩苹果汁具有以上的功能作用,从而大大扩大了市场对浓缩苹果汁的需求。
4.厂址选择洛川是陕西西安的一个县级城市,自古以来以“苹果之乡”著称,这里昼夜温差大,苹果的含糖量高,有利于浓缩苹果汁的制造;洛川对于乡镇来说,还是较发达的,交通运输便利,由于浓缩果汁的保质期一般在12个月左右,无需太关注交通运输方面;该城市一般都采用自来水,均能符合企业生产用水要求;劳动力方面,由于城市人口密集,应该把食品厂建在离城市不远的郊区,一方面可以有较多的劳动力,另一方面可以减少企业污染对居民的影响,同时在郊区,建厂经费也可以大大减少。
洛川位于我国西部,自古以来我国人口集中在东南部,东南部较西部发展速度快,把食品厂建在西部,还可以加快西部的发展。
综上述的观点,浓缩苹果汁食品厂建立在洛川是可行的。
二、产品方案及班产量的确定1.班产量确定①年产量:Q=10000t②《③生产班制:淡季2班制,旺季3班制(这样有利于劳动力平衡,设备充分利用,成品正常销售,便于生产管理,经济效益提高)④工作日:苹果的成熟季节在秋季,所以定8、9、10、11、12、1月份为旺季,工作日(t旺)为130d, 2、3、4月份为淡季,工作日(t淡)为75d,5、6、7月份为设备检修日(一方面由于这几月份苹果原料难以储藏,苹果的含糖量大大减少,生产的苹果汁质量也会相应的减少:另一方面接下来的8、9、10、11、12、1月份为企业的旺季,对设备的要求度高,以便产品能更好地连续生产),余下的63d为节假日(其中工作日一周只有单休日,国庆只有三天休息日),则全年浓缩苹果汁生产天数为:t=t旺+t淡=130+75=205d④班产量q班:班产量q班计算公式如下:q班= Q∕k(3t旺+2t淡)式中 q班——班产量,tQ——年产量,t|k——设备不均匀系数,k=~计算:q班=10000∕(3×130+2×75)=(t/班)2.产品方案三、工艺流程及论证1.工艺流程:原料验收——挑选——清洗——破粹——榨汁——过滤——灭酶——蒸发——酶解——超滤——灭菌——无菌灌装——浓缩苹果汁2.工艺论证⒈原料验收企业首先要确定采购区域,保证采购区域周围没有化学污染及该苹果区域未使用国家禁止的农药,苹果成熟期前,应派相关部门对原料苹果进行定期检查其质量的好坏。
生产过程中,苹果验收按以下要求进行:《A必须是合格供应商提供的原料,对原料的生长情况要大致了解B符合农药残留检验报告C产品质量符合要求,腐烂率超标(6%)的不收D质检员当场验收⒉挑选拣选的目的是剔除霉烂的、带病虫害的、破损的和未成熟的苹果以及混杂于其中的异物,有利于降低农药残留,减少微生物的污染及保持苹果汁的正常风味,在拣选台上完成工作。
⒊清洗在洗果台上通过毛刷及水流喷淋进行苹果的清洗。
·⒋破碎榨汁前必须进行破碎,破碎粒度要适当,要有利于压榨过程的果浆内部形成果汁排汁通道。
综合很多方面因素,将破碎粒度控制在~3cm,通过破碎机将苹果破碎,以备后面的压榨程序⒌榨汁压榨机采用的是带式压榨机。
在压榨过程中果浆尽量分布均匀,果浆厚度控制在3~6cm之间,如果需要,还可以进行二次压榨,具体方法为在第一次压榨后的果渣中加入等量的水浸渍后进行第二次压榨,可提高果汁的出汁率。
⒍过滤采用双联过滤器,由两台不锈钢过滤器并联而成,具有结构新颖合理、密封性好、流通能力强、操作简便等诸多优点,应用范围广泛、适应性强的多用途过滤设备,能准确地保证过滤精度,并能快捷地更换滤袋,过滤基本无物料消耗,使得操作成本降低。
⒎灭酶!采用板式灭酶换热器,使酶失活,防止果汁产生褐变,提高果汁的商品价值。
⒏蒸发过滤后的果汁需要浓缩,以便有利于储藏和运输。
浓缩通常是以蒸发方式进行,该企业采用三效外循环式真空蒸发器方法进行浓缩,该蒸发器可以蒸发浓度较高、粘度较大的溶液,且具有传热效率高,受热时间短的特点,管道清洗较为方便。
这种方式浓缩法可以大大减少浓缩的损耗。
清汁进入蒸发器浓缩,浓酸至原体积的1/6左右,可以控制最终含糖量在56%~58%之间。
⒐成分调节主要是糖和酸的调整,洛川苹果的含糖量在 %,含酸量在%,成品苹果汁的含糖量要求在56%,糖酸比为13:1~15:1(该设计采用14:1),若产品不符合糖酸比要求,则应向苹果汁中加入糖和酸以改善苹果汁的风味。
⒒酶解在这个过程中,加淀粉酶、果胶酶进行酶降解,经检测均为显阴性时,再根据终产品色值要求,在酶解罐中采取加或不加活性炭澄清剂。
经过酶降解和澄清后的果汁直接进入超滤装置中,以备精过滤。
⒓超滤…超滤开机时要求浊度为~时,方可向下一工序运料。
每个小时要对渗透做有无杂质感官检测。
在超滤渗透流量不能满足生产需要时,应按规定程序清洗,清洗前须加水稀释果汁,过滤至糖度低于时,超滤方可排空。
⒔灭菌采用瞬时高温灭菌机,对浓缩苹果汁进行灭菌,使产品达到无菌要求,从而达到延长浓缩苹果汁的保存期。
⒕无菌灌装无菌灌装的三个条件:(1)物料的无菌(2)包装材料的无菌(3)灌装环境的无菌。
采用灌装机进行灌装,灌装前先将灌装口喷射高温蒸汽,杀死可能存在的微生物,再开始灌装,灌装后的成品直接入库保存。
