Fresh fruit and vegetable storage, preservation library, Shanxi Lung preservation

Cold classification and presentation decompression library for a mini-refrigerator is mainly China's current management model of agricultural production and rural economic and technological level of domestic gas storage library, as well as fruit and vegetable distribution center, wholesale markets and supermarkets demand, research and development operations simple, reliable performance, the effect of good storage facilities. "Green" brand Mini Cold and special equipment are eligible for national patent (Patent No. ZL98248518 · 8 and ZL98248517 · 4), has been included in the National Spark Program to promote the project (No. EA610019). Library body building and equipment, the total investment of 400 million yuan, fruits and vegetables can be stored for about 20,000 kilograms. Lung Preservation Technology Development Co., Ltd. Shanxi, Shanxi Academy of Agricultural Sciences, Institute of Science and Technology under the storage and preservation of agricultural enterprises, but also the National Agricultural Science and Technology Park (Taiyuan) enterprises in the park. The company is the vice president of Shanxi Province, Refrigeration and Air Conditioning Industry Association unit, with refrigeration equipment installation and maintenance of B qualification, can undertake the total cost of five hundred million less refrigeration, air-conditioning equipment installation, maintenance. Relationship between refrigerating capacity and freezing time if you know one day refrigeration equipment heat load 240000kcal, freezing cold for an hour 24 hours compressor running 18 hours. So choose refrigeration accessories refrigeration capacity 13340kcal / hr freezer. But we want to shorten the freeze time again, whether to increase the capacity of the freezer can? In fact, the nature and duration of freezing frozen material, packaging, articles in the monthly cold storage packing mode cents have a great relationship. We give ... a simple example can illustrate this problem. Cold storage equipment is assumed that there is a large 25C pork, fruit preservation of 5cm thickness, with a total weight of 5kg into a storage temperature of a 18'C 'the freezer; Similarly, there are a number of pork sliced ??25 ℃, the total weight is 5kg. cross-sectional area is the same, but each slice thickness of 0.1cm, these meat apart into another storage temperature flattening a 18'C. refrigerating capacity is also the same freezer. So, which side of pork fastest freeze all fresh fruits and vegetables to a 15 libraries, C do? I believe that readers will choose the latter. Because the piece of pork is very easy because the outer layer of meat frozen after forming a layer of thermal Hang cold storage, heat the pork to spread outside the space within the required time longer, it freezes more slowly. In addition to freezing the shape of goods per se, characteristics and packaging, the freezer frozen product display, the problem will affect the airflow freezer to freeze time. So if you find calorie counting according to the selection of the freezer, but the goods can not freeze in the time required to ask the desired temperature, then we must consider whether the thickness of the frozen product itself is too large, the packaging is too low thermal conductivity ( even cause insulation), stacked freezer items is too dense, the library's air circulation is adequate. Therefore, the impact of freezing time in addition to the selection of the refrigerating capacity freezer is appropriate, good and bad effects of heat transfer freezer to freeze the length of time is the main reason for the decision. Because the heat transfer mechanism freezer is the decision to freeze the rate of speed in the heat away items of the main factors.
