Points to note when choosing Cake Showcase
Cake Showcase is a common product in the society. There are various cake products in the cabinet. It is an indispensable refrigerator in many supermarkets and cake shops. So what should we pay attention to when choosing Cake Showcase?
one, the structure of the preservation cabinet is stronger
The structure of the cabinet is directly related to the length of life of the preservation cabinet. There is an integral angle steel frame support between the outer shell and the inner tank of the high-quality supermarket fresh-keeping cabinet, and its function is equivalent to that there are steel bars in the cement prefabricated board, and the firmness is greatly increased. After the door frame is completely welded and formed, the whole is foamed at one time, which avoids the defect that the door frame is not firmly assembled and the cabinet door is easy to fall off. The integral steel frame has obvious advantages in one-time forming. Why don't other manufacturers adopt it? Because the fixture requirements are complicated and the installation is difficult, it is impossible for manufacturers to adopt this structure and technology for the interests of consumers.
two, to see if the material is good
All evaporating tubes in high-quality cabinets are made of high-quality copper coils and processed into wide-faced special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. The use of an appropriate thickness not only ensures a long service life, but also makes the appearance of the fresh-keeping cabinet flat and strong. Copper pipes have better cooling effect and better corrosion resistance than aluminum pipes or composite pipes. High-quality copper coils have the advantages of higher cleanliness in the pipes and fewer pipe joints, which can effectively prevent leakage or blockage in the refrigeration system. The circular tube is processed into a rectangle, so that the contact between the evaporation tube and the cold transfer liner is changed from point contact to surface contact, which enlarges the transfer area and accelerates the cooling speed.
Three, look at the power of the compressor
All high-quality cabinets use commercial compressors. Commercial compressors have good starting performance and complete specifications from small to large cooling capacity, and can be configured in different ways according to different product prices. Only commercial compressors can adapt to the harsh operating environment of commercial fresh-keeping cabinets, frequent starts, and long running time, ensuring product price and quality. Although the price of commercial compressors is higher than that of household compressors, the failure rate is less than two thousandths.
Four, look at constant temperature and cooling speed
The working temperature of high-quality cabinets is distinguished by the most suitable temperature for food storage or preservation. The refrigerated cabinet is suitable for plant foods, which can ensure that the juice contained in the food is not lower than the freezing point and keeps its fresh state. The temperature of the freezer is -18 degrees Celsius, and the shelf life of food stored at this temperature is up to 1 month. The high-quality fresh-keeping cabinet not only guarantees that the temperature of the fresh-keeping cabinet meets the requirements according to the standard, but also makes the cooling speed of the high-quality fresh-keeping cabinet faster by using a special-shaped evaporating tube and matching a unit with an appropriate cooling capacity.
fives, look at the insulation effect
In the production process of the cabinet, the insulation performance of the insulation layer is not only an important quality index of the fresh-keeping cabinet, but also an important factor in the economical use of the fresh-keeping cabinet. In order to achieve good thermal insulation performance, appropriate raw materials must be selected, and the bulk density and cell diameter must be controlled within the optimal range. Therefore, only by adopting the ability to control the material temperature, cooperate with special fixtures and master the mature foaming process, can the cabinet with good heat preservation effect be produced.
six, look at the effective volume
The signs of the technical parameters of the high-quality preservation cabinets are in accordance with the requirements of international standards, and all have passed the random inspections of the national quality and technical supervision agency over the years.
