High quality characteristics

1. The effective volume of supermarket fresh-keeping cabinets is larger

The marks of the technical parameters of the high quality fresh-keeping cabinet are all qualified according to the international standard and have been sampled by the national quality and technical supervision institution for many times over the years.

2. Supermarket crisper The crisper has constant temperature and fast refrigeration speed

The working temperature of the high quality supermarket crisper is divided into the optimum temperature conducive to food storage or preservation. The refrigerator is suitable for plant food, which can ensure that the juice contained in food is not lower than the freezing point and keep its fresh state. The freezer temperature is -18 degrees Celsius. The shelf life of food stored at this temperature is up to 1 month. The high quality fresh-keeping cabinet not only ensures that the temperature of the fresh-keeping cabinet meets the requirements according to the standard, but also makes the refrigeration speed of the high quality fresh-keeping cabinet faster by adopting special-shaped evaporating tube and matching the unit with appropriate cooling capacity.

3. Commercial high-power compressor for supermarket crisper

The high quality fresh-keeping cabinets are all commercial compressors. Commercial compressors in addition to good starting performance, and cooling capacity from small to large complete specifications, according to the different requirements of different products to do different configurations. Only commercial compressors can adapt to the harsh operating environment, frequent start-up times and long running time of commercial fresh-keeping cabinets to ensure product quality. Although commercial compressors are more expensive than domestic ones, the failure rate is less than two parts per thousand.

4. Supermarket fresh-keeping cabinets are made of better materials

All the evaporating tubes of the high quality supermarket crisper are made of high quality copper coils and processed into wide shaped ones. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is even. The use of appropriate thickness not only ensures long service life, but also makes the appearance of the fresh-keeping cabinet smooth and firm. Copper pipe is better than aluminum pipe or composite pipe cooling effect, better corrosion resistance, high quality copper coil pipe has the advantages of high internal cleanliness, less pipe joints, can effectively prevent the refrigeration system leakage or blockage of the fault. The circular tube is processed into a rectangle, so that the contact between the evaporator tube and the cooling tank is changed from point contact to surface contact, which expands the transfer area and speeds up the cooling speed.


5. The preservation cabinet in the supermarket has better insulation effect

The heat insulation performance of the insulation layer is not only an important quality index but also an important factor for the economical use of fresh-keeping cabinets in the production process. In order to achieve good adiabatic performance, it is necessary to select proper raw materials and control the bulk density and pore diameter within the optimal range. Therefore, only by using the material temperature can be controlled, with special fixture, master the mature foaming process, can we produce the preservation cabinet with good heat preservation effect.

6. The structure of supermarket crisper is more solid

The sturdiness of the structure of the storage cabinet is directly related to the service life of the storage cabinet. There is an integral Angle frame between the shell and the inner tank of the high quality supermarket fresh-keeping cabinet, which is equivalent to placing steel bars in the cement prefabricated board, increasing the firmness. After the door frame inside all welds to form, whole disposable foams form, avoided because the door frame assembly is not firm, the defect that cabinet door falls off easily. The advantages of integral steel frame forming in one time are obvious, why other manufacturers do not use it? Because jig requirement is complex, install clamp difficulty is big, not be the manufacturer that considers for consumer interest everywhere, impossible to use this kind of structure and craft.
