  • quick freezing working principle

    Quick freezing Rapid freezing of food by exposure to a blast of air at a very low temperature. Unlike slow freezing, very small crystals of ice are formed which do not rupture the cells of the food and so the structure is relatively undamaged.
    quick‐frozen food is commonly defined as one that has been cooled from a temperature of 0 °C to −5 °C or lower, in a period of not more than 2 hours, and then cooled to −18 °C.
    The basic principle Mechanical cold storage This method of storing fruits in a good adiabatic building, equipped with mechanical  cold storage unit, and according to the variety of fruits on the storage temperature, humidity and ventilation requirements of the cold storage system for human regulation and control , So the storage time longer, the effect is better. A, mechanical  cold storage principle. 
    Mechanical  cold storage is the use of liquid gas (refrigerant) is very low temperature, it evaporated under low pressure into gas, which absorb heat, to achieve the purpose of cooling. In addition to the low boiling point refrigerants, but also requires no harm to human organs, the metal does not play a corrosive effect, no risk of combustion and explosion, does not react with the lubricant, but also should have good heat absorption, evaporation More heat absorption, low pressure in the high pressure condensing system, lower viscosity and cheaper prices.

  • What is the Quick Freezer

    The First cold chain quick-freezing machine Introduction
     Quick-freezer machine is a fast freeze equipment, the product in a relatively short period of time by -35℃ even more lower temperature make the product center temperature reaches -18℃, (3cm thick below the frozen product (excluding packaging), within 30min product center temperature from +15 down to -18 ℃ As the standard), in order to achieve the product lattice does not change, the water does not precipitate, to achieve product reversibility of fresh. Easy to transport products, products to achieve the complementary season, the maximum extent to ensure that the product of fresh.
    The working principle
    The quick-freezer unit is mainly composed of a quick-freezer machine, a refrigeration system and an electrical control system. The worker will put a frozen plate of frozen food or directly through the quick-frozen inlet into the quick-freezing machine ,so that the product is heated by the central temperature Or other temperatures, to -18 degrees.
    Q uick Freezer machine classification
    Tunnel-type freezer
    Simple structure, easy operation, wide range of applications. Affordable. Suitable for a variety of products quickly frozen. 
    Such as meat seafood.

    Spiral type freezer
    The use of spiral transmission products, small footprint, the amount of freezing, so this mechanism can produce a larger production of quick-frozen equipment, the current application is also more, mainly used in the food industry frozen industry.such as:meat seafood.

    Fluidizing quick-freezer machine (IQF)
    The use of the end of the way to make the product in the fluid process to achieve rapid freezing, suitable for  individually product quick freezing.such as : fruit and vegetable etc

    Hydraulic Contact Plate Freezer
    The internal aluminum plate of the hydraulic contact plate freezer can be moved horizontally up and down, and heat exchange is achieved by double-sided contact with the frozen product. The product can be quickly frozen and the corresponding refrigeration system can be matched according to the customer's needs. The quick-freezing machine is suitable for land and fishing Frozen pieces of food, such as fish, surimi, shrimp, shellfish and so on.
