Recommended for different types of freezers, teach you how to choose a freezer

Freezers are widely used in supermarkets, shopping malls, convenience stores and other commercial business places because of their good refrigeration and preservation functions. Of course, it is also suitable for storing food at home. At present, there are various types of freezers on the market, including vertical freezers and horizontal freezers according to styles, direct freezers and air-cooled freezers according to refrigeration methods, and refrigerators, freezers, refrigerated freezers, and so on according to functional purposes. So which freezer is better? How to choose a freezer?

01. Distinguish by place of use

Household freezer:

Household freezers are generally fashionable and novel in style, with a relatively small volume, mostly between 50 and 200 liters. They are mainly horizontal top-door type and can be used to store various ingredients, such as fruits and vegetables, instant pasta, meat and seafood, etc. There is also a small ice bar specially used to store red wine and tea leaves.

Commercial freezers:

Commercial freezers have a large volume and a wide range of uses. They are mostly used in shopping malls, supermarkets, cold drink shops, frozen goods stores, hotels, restaurants, and other commercial establishments. In addition, commercial fresh-keeping cabinets are subdivided into fruit cabinets, flower cabinets, cake cabinets, deli cabinets, beverage cabinets, order cabinets, ice cream cabinets, beer cabinets, drug refrigerators, etc. The main difference is in the temperature control range to meet the appropriate storage temperature of different items.

02. According to the refrigeration method

Direct freezer:

The internal structure of the direct-cooled freezer is simple, so the power consumption is low, the noise is low, and the price is relatively affordable; however, its cooling speed is relatively slow, and it is not very uniform. The freezer is prone to water accumulation and frost, and it needs to be manually defrosted regularly.

Air-cooled freezer:

The internal structure of the air-cooled freezer is relatively complex, and the cold air in the box is forced to convect, resulting in fast cooling speed, good temperature uniformity, and a defrost system, eliminating the need for manual defrosting. However, its power consumption will be large, and the internal fan will also increase its noise, making it more expensive.

03. Differentiate according to temperature control

Dual temperature freezer:

The double-temperature freezer has two greenhouses, one is refrigerated and the other is frozen, and the middle is separated. It can be refrigerated and frozen at the same time, but they cannot be used interchangeably. The functions are fixed and the synchronization does not interfere. Therefore, the double-temperature freezer can be stored at different temperatures according to different ingredients, which is more convenient to use.

Single temperature freezer:

The single-temperature freezer has only one greenhouse, one temperature, or refrigeration or freezing, and the temperature is -12-10 degrees, which is adjusted in this temperature range. Therefore, the single-temperature freezer can only choose one storage method at a time, which is very inflexible to use, but consumes relatively little power.

04. Distinguished by functional use

Refrigerated cabinet:

The temperature in the refrigerator cabinet is maintained within the range of 0 to 10 ° C. It can be used to store beverages, eggs, dairy products, fruits, vegetables, etc., and can also be used to store medicines, vaccines, flowers, etc. The former is mostly a vertical side door, while the latter is mostly a horizontal top door.

Freezer:

The temperature in the freezer is usually below -18 ° C, which can be used to freeze food and store frozen food or other items for a long time, such as meat and seafood. Its styles are mostly horizontal top door structures, and a few are vertical side door structures.

Refrigerated freezer:

The box body is divided into two or more double-door or multi-door freezers with different temperature storage compartments by thermal insulation. Each has a cabinet door that can be opened, at least one of which is a refrigerator compartment and at least one is a freezer compartment, which is used to store refrigerated and frozen foods respectively. Usually a horizontal top door structure.

Refrigerated and frozen exchange cabinets:

A new type of single-door multi-function freezer, through the conversion of the thermostat, the freezer can be used as a refrigerator or freezer to meet the requirements of users in different periods. This is a new type of product developed by Chinese freezer manufacturers for the characteristics of the Chinese market.
