One：Effective volume is larger
The technical parameters of the high-quality vending machine are all in accordance with the requirements of international standards, and have passed the sampling inspections by the State Quality and Technical Supervision Agency over the years.
Two：The vending machine has a constant temperature and fast cooling speed
The operating temperature of a premium vending machine is distinguished by the optimum temperature for the storage or preservation of the food. The vending machine is best suited for foods of a plant nature, ensuring that the juice contained in the food is not below the freezing point and remains fresh. The freezer temperature is -18 degrees Celsius. With this low temperature, the shelf life of the food can be as long as 1 month. The high-quality display cabinet not only guarantees the temperature in the cabinet according to the standard, but also improves the cooling speed of the high-quality vending machine by using the special-shaped evaporation tube and matching the unit with the appropriate cooling capacity.
Three：Commercial high power compressor
High-quality vending machines all use commercial compressors. Commercial compressors have different starting performances, and the cooling capacity is from small to large, and can be configured differently according to different requirements of the product. Only commercial compressors can adapt to the harsh environment of commercial vending machines, frequent start-ups and long running times to ensure product quality and low failure rate.
Four：Vending machine materials are better
All the high-quality vending machines are made of high-quality copper coils and processed into wide-faced shapes. The surface of the stainless steel plate is smooth and the whole plate is even and thin. The use of an appropriate thickness guarantees a long service life and a smooth and sturdy appearance of the vending machine. The copper tube has better cooling effect than the aluminum tube or the composite tube, and has better corrosion resistance. The high-quality copper coil has the advantages of high cleanliness inside the pipe and few pipe joints, which can effectively prevent the leakage or blockage of the refrigeration system. The circular tube is processed into a rectangular shape, so that the contact between the evaporation tube and the cold-passing inner liner is brought into surface contact by the point contact, the transfer area is enlarged, and the cooling speed can be accelerated.
Five：Vending machines have better insulation
Vending machine, the thermal insulation performance of the vertical air cabinet production process is not only an important quality indicator of the vending machine, but also an important factor in the economics of the vending machine. In order to achieve good thermal insulation properties, the appropriate raw materials must be selected to control the bulk density and cell diameter in the optimum range. Therefore, only by using the temperature control, with special fixtures, mastering the mature foaming process, can we produce vending machines with good thermal insulation effect.
Six：Structure is more sturdy
The structural rigidity of the cabinet of the supermarket vending machine is directly related to the length of use of the display cabinet. There is an integral angle steel frame support between the outer casing and the inner tank of the high-quality vending machine. Its function is equivalent to the reinforcement of the cement prefabricated plate, and the solidity is greatly increased. After the door frame is completely welded and formed, the whole body is foam-formed at one time, which avoids the defect that the door frame is not tightly assembled and the door is easy to fall off.
