How to choose fruit and vegetable display freezer correctly

Nowadays, there are many varieties of fruit and vegetable refrigerators on the market, but the quality is uneven. How can consumers get their eye-catching eyes and buy high-quality fruit and vegetable display refrigerators?

First, the heat preservation effect of the fruit and vegetable display freezer is better. The pros and cons of the insulation performance of the fruit and vegetable display refrigerator during the production process are not only an important quality indicator of the fruit and vegetable display refrigerator, but also an important factor in the economical use of the fruit and vegetable display refrigerator. 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 we produce vertical refrigerators and vertical freezers with good thermal insulation effect.

Second, the effective volume is larger. The technical parameters of the high-quality fruit and vegetable display freezer 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.

Third, commercial high-power compressors. All high-quality fruit and vegetable display refrigerators use commercial compressors. Commercial compressors have good starting performance and complete specifications from small to large refrigeration capacity, and can be configured in different ways according to different requirements of the product. Only commercial compressors can adapt to the harsh operating environment of commercial refrigerators, frequent start-up times, and long running time to ensure product quality. Although the price of commercial compressors is higher than that of domestic compressors, the failure rate is less than two thousandths.

Fourth, the structure is stronger. The solidity of the structure of the fruit and vegetable display freezer is directly related to the length of service life of the fruit and vegetable display freezer. There is an integral angle steel frame support between the outer shell and the inner tank of the high-quality fruit and vegetable display freezer. Its function is equivalent to that there are steel bars placed in the cement prefabricated board, and the firmness is greatly increased. After the door frame is completely welded and formed, the whole is foamed and formed at one time, which avoids the defect that the door frame is not firmly assembled and the fruit and vegetable display freezer door is easy to fall off.

Fifth, the temperature of the fruit display freezer is constant and the cooling speed is fast. The working temperature of the high-quality fruit and vegetable display freezer is distinguished by the most suitable temperature for food storage or preservation. The freezer 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 freezer not only guarantees that the temperature of the freezer meets the requirements according to the standard, but also makes the high-quality fruit display freezer cool faster by adopting the special-shaped evaporating tube and matching the unit with the appropriate cooling capacity.

Sixth, the quality of the fruit and vegetable display freezer is better. All the evaporating tubes of the fruit and vegetable display freezer are made of high-quality copper coils and processed into a wide surface profile. 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 fruit and vegetable display refrigerator 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 high cleanliness in the pipe and fewer pipe joints, which can effectively prevent internal leakage or blockage failures in the refrigeration system. The round 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 speeds up the cooling speed.
