Reasons why display cabinet glass doors are common in convenience stores or large supermarkets

Today's fruit and vegetable display cabinets all use large display cabinet glass doors. What is the significance? There are a variety of fruit and vegetable freezers in the market, but the quality varies. How can customers open their eyes and choose a quality fruit and vegetable display case freezer?

First of all, the heat preservation effect of the fruit and vegetable display cabinet is better. In the production process of the fruit and vegetable display freezer, the heat insulation function of the heat insulation layer is not only an important quality index of the fruit and vegetable display freezer, but also an important factor in the economical efficiency of the fruit and vegetable display freezer.

In order to obtain good thermal insulation performance, it is necessary to select suitable raw materials and control the bulk density and cell diameter within a good range. Therefore, only by adopting material temperature control, special fixtures and mature foaming technology can we produce upright refrigerators with good heat preservation effect.

Second, the useful amount is greater.

The technical parameters of the high-quality fruit and vegetable display freezer meet the requirements of international standards, and have passed the sampling inspection of the State Bureau of Quality and Technical Supervision many times.

Third, commercial high-power compressors. High quality fruit and vegetable display freezers are commercial compressors.

Commercial compressors not only have excellent starting performance, but also have small to large cooling capacity and complete specifications, and can also be made according to different requirements of the product. Only commercial compressors can adapt to harsh environments, and commercial refrigerators are characterized by frequent startup and long-term operation to ensure product quality. Although the price of commercial compressors is higher than that of household compressors, the failure rate is less than two thousandths.

Fourth, the structure is more solid. The structural firmness of the fruit and vegetable display freezer is directly related to the service life of the fruit and vegetable display freezer. There is an integral angle steel structure support between the shell and the inner tank of the high-quality fruit and vegetable display freezer, which is equivalent to the reinforcement in the cement prefabricated board, which greatly improves the firmness.

After the door frame is welded and formed, the entire door is foamed at one time, which avoids the disadvantage that the door of the fruit and vegetable display cabinet is easy to fall due to loose assembly of the door frame.

Fifth, the temperature of the fruit display cabinet is constant and the cooling speed is fast. The operating temperature of a refrigerator is characterized by a temperature well suited for food storage or preservation.

This refrigerator is suitable for vegetable food, which can ensure that the juice contained in the food does not drop below freezing point and stays fresh. The temperature of the freezer is -18 degrees Celsius, and the shelf life of food stored at this temperature is one month. A high-quality freezer not only ensures that the temperature of the freezer meets the standard requirements, but also uses a special-shaped evaporation tube and deploys a unit with an appropriate cooling capacity, so that the high-quality refrigeration speed of the fruit display freezer is faster.

Sixth, the raw materials in the freezer for fruit and vegetable display are better. All evaporation tubes of fruit and vegetable display freezers are made of high-quality copper coils and processed into large-area tube shapes. The surface of the stainless steel plate is lubricated and lubricated, and the thickness of the whole plate is uniform.

The right thickness not only ensures a long service life, but also gives fruit and vegetables a flat and firm look to your refrigerator. Copper tubes provide better cooling and corrosion resistance than aluminum or composite tubes. The advantages of high-quality copper coil tubes are high cleanliness inside the tubes and fewer pipe joints, which can effectively prevent leakage or blockage of the refrigeration system.

The circular tube is regarded as a rectangle, so that the contact between the transpiration tube and the cooling box changes from a point contact to a surface contact, thereby expanding the transfer area and speeding up the cooling speed.
