Refrigerated form

There are two main forms of evaporators used in refrigerated storage: one is a cooling fan and the other is a tube evaporator.

Air cooler

The air cooler has been used in more than a decade, but in the course of many years of use, the drawbacks of food drying, food color change, fan energy consumption and failure have become more and more prominent, so that food operators and refrigeration engineers are Actively looking for ways to solve this problem.

 

Tube evaporator

The tube evaporator is mainly made of steel tube and copper tube. Due to the problem of materials, there are certain disadvantages.

When the steel pipe and the copper pipe are used in the light pipe, the heat transfer coefficient between the inner side of the pipe and the outer side of the pipe is large, which causes waste of materials. The copper pipe is too expensive, the internal cleanliness of the steel pipe is difficult to ensure, and the evaporator weight is too large, so that the refrigeration is performed. The cost of the building structure of the library has increased, and many unfavorable factors have restricted its development. The patented aluminum row not only solves the above problems, but also has more advanced performance.

2 refrigeration storage features

The characteristic of the refrigerated cold storage is that the instrument is put into the cold storage from time to time. The temperature of the cold storage reaches -20 °C after a period of time. There is no special requirement for this time, but the storage temperature is strict, at -18 °C-23 °C. Between the typical low temperature storage, but the storage of cold drinks containing dairy products, the storage temperature should be set at -20 ° C-28 ° C, but these two different temperatures require different levels of equipment, equipment investment has a big gap. Refrigeration is generally a food that will have such a need, in order to maintain its required temperature and quality storage.

Because the temperature drops below -150 °C, the food freezing rate is higher, and the micro-objects and enzymes basically stop activity and growth, and the oxidation is also very slow. Therefore, the food can be stored for a long time and has a good quality of refrigeration. In addition, chilled foods also require a relatively stable temperature inside the store, and excessive temperature fluctuations will cause food spoilage.

3 cold storage technology

The library body is made of hard polyurethane or polystyrene foam insulation sandwich panel, and is filled with plastic length and specification by high-pressure foaming process to meet the different requirements of users. Its characteristics are: good insulation performance, heavy moonlight corrosion, anti-aging, beautiful appearance.

 

4 aluminum refrigerator

application

The refrigerator is mainly used for low-temperature refrigeration of food, frozen meat, frozen aquatic products, frozen seafood, and poultry. Mainly used in food factories, meat joint factories, poultry and egg warehouses, supermarkets, troops, hotels and other places.

Aluminum chilling advantages:

The use of refrigerated aluminum rows has the following five major advantages:

1. Energy saving effect is remarkable;

2. Good thermal conductivity;

3. Light weight, easy to install, and less food consumption;

4. The electric heating cream function solves the problem that the aluminum tube is difficult to be defrosted;

5. high pressure resistance pipe, clean system, and the service life of the compressor is prolonged.
