Features

Large capacity storage: Usually only one large capacity freezer is available, suitable for commercial occasions or households that require large quantities of frozen food storage, and can meet the storage needs of large quantities of food.

Strong freezing ability: Generally, it has quick freezing function. Under the specified freezing load test conditions, more than 4.5kg of food can be frozen within 24 hours for every 100L of effective volume, and the temperature inside the cabinet can be maintained at no higher than -18 ℃ for long-term storage of frozen food. Like the Aucma BC/BD-401HNE freezer, it has a powerful freezing power of 18.5kg/12h, which can quickly freeze through ingredients such as beef, mutton, pork, fish, shrimp, scallops, etc., retaining the original fresh taste and locking in the original nutrients.

Precise temperature control: PartialfreezerAdopting multi-stage temperature control, with wide temperature adjustment function. The Aucma BC/BD-401HNE freezer adopts eight temperature control levels, with a temperature range of -38 ℃ to 10 ℃. The strong cooling level can quickly freeze ingredients to -38 ℃ in a short period of time, meeting the freezing needs of different ingredients.

Good insulation performance:freezerThe insulation capacity is crucial. For example, the Aucma BC/BD-401HNE freezer has a 70mm thick insulation layer and uses high-pressure microporous foaming technology to tightly lock the air conditioning without consuming electricity. Even in the event of a power outage, it can ensure 120 hours of insulation and keep the ingredients fresh for a long time.

classification

Classified by purpose: It can be divided into storage cabinets and display cabinets. Storage cabinets are mainly used for storing frozen food, with temperatures generally controlled below -18 ℃; Display cabinets have display functions and generally use insulated glass as the door body. The temperature is controlled between 0-10 ℃, mainly used for selling cold drinks, fruits, etc.

Classified by external structure and placement form: it can be divided into horizontal refrigerators, vertical refrigerators, desktop refrigerators, etc. Horizontal refrigerators generally have a length greater than their width and a top opening door; The height of the vertical freezer is greater than its width, and the front door is opened; Desktop refrigerators are relatively short and can be used on counters.

According to the structure of the refrigerator door, it can be classified into single development foam door refrigerators, double opening foam door refrigerators, glass door refrigerators, etc. Single development bubble door refrigerators are generally installed horizontallyfreezerDouble opening foam door refrigerators are used for larger horizontal capacityfreezerGlass door refrigerators are generally used for commercial purposes to display the goods inside the cabinet.

Cooling method

Direct cooling: It is an inward coil that uses the cooling radiation generated by the flow of refrigerant inside the coil to cool down, without a fan inside the cabinet. Its advantages are simple structure, small airflow in the cabinet, and less loss of food moisture. However, the freezer is prone to freezing and needs to be regularly de iced.

Air cooled type: using a fan to promote gas flow inside the freezer and achieving cooling effect through an evaporator, it belongs to frost free typefreezerIts advantages are fast cooling speed, uniform distribution of cooling capacity, and no freezing of the walls inside the freezer, saving the trouble of removing frost. However, the items inside the cabinet need to be stored in plastic bags, otherwise there will be a large loss of moisture.
