Among them, a freezing device is a device that can reduce the product temperature and smoothly pass through its maximum frozen ice crystal area to be frozen. For example, commonly used in frozen food are tunnel-type continuous freezing devices, fluidized single continuous freezing devices, and spiral continuous freezing devices, all of which belong to forced ventilation freezing equipment.

Forced ventilation freezing equipment: A freezing equipment that freezes products through rapidly circulating cold air. It is a freezing device that uses air as a refrigeration medium to complete heat exchange. Heat and cold are first transferred from the refrigerant to the air, and then from the air to the frozen object.
There are many types, including tunnel type, fluidized type, spiral type, blast type, etc.
Contact freezing equipment: A freezing equipment in which items are frozen by contacting a cold surface.
Deep freezing equipment: Equipment that uses liquid nitrogen or dry ice as a refrigerant to achieve deep low-temperature freezing.
Batch-type freezing equipment: A refrigeration equipment suitable for only a single filler at a time.
Continuous freezing equipment: Equipment in which cooled goods can be continuously sent into the freezer for freezing during the cooling process.
Immersion freezing equipment: An insulated box containing cooling liquid. Goods can be frozen by being immersed in this liquid.
Plate freezing equipment: A contact freezing equipment with a cold surface being a metal plate, using several plates as evaporators.
Shelf freezing equipment: A freezing equipment in which items are placed on a shelf with a refrigerant circulating inside.
Fluidized freezing equipment: A rapid freezing equipment in which granular food is in a suspended or semi-suspended state in a fluidized bed during the freezing process.
Spiral quick-freezing equipment: A food quick-freezing equipment in which the conveyor belt runs along a spiral trajectory.
Mesh belt quick-freezing equipment: A rapid equipment for food freezing by means of a mesh belt conveyor.
Plate and belt quick-freezing equipment: A rapid equipment for rapid freezing by means of a plate and belt conveyor.
Liquid nitrogen quick-freezing equipment: Equipment that completes the rapid freezing of food by liquid nitrogen absorbing the heat from food and evaporating in an insulated room.
Liquid carbon dioxide quick-freezing equipment: Equipment that completes the rapid freezing of food by liquid carbon dioxide absorbing the heat from food and evaporating in an insulated room.
For the freezing of food, there are many traditional freezing methods.
Generally, according to the different contact methods between the frozen object and the cooling medium, there are three methods: air freezing method, indirect contact freezing method, and direct contact freezing method. Among them, the indirect contact freezing method and the direct contact freezing method are collectively called contact freezing. With the development of freezing technology, some emerging freezing methods have emerged, such as film-coated freezing method, isothermal freezing method, and high-pressure freezing method. Each freezing method has different freezing devices.
