Individual Quick Freezing usually abbreviated IQF is a freezing method used in food processing industry. The freezing process takes very short time. It does not allow the formation of large ice crystals in the product’s cells which would destroy the membrane structures at molecular level. This makes the product keep its shape, color, smell and taste after defrost, at a far greater extent.
Individual quick freezing machine, also named Air Blast freezers include the cabinet, tunnel, fluidized bed and spiral belt units.

The frozen food tissue is influenced on freezing rate; the extent of damage depends on the size of the crystals and hence on the rate of heat transfers, means a flash freezing process.
Fluidization frozen is an ideal way to achieve the IQF (Individually Quick Freezing), which is suitable for freezing the flakes, lumps, strip and granular vegetables with rapid freezing speed.
How to freeze fresh vegetables?
Tunnel Quick Freeze Machine is the flash freezing equipment in frozen food, freezing vegetables process.
This air blast tunnel freezer utilizes cold air at high speeds and is designed in various configurations. They are used to freeze very dense products or products packed in big packages which can be continuously conveyor and exposed to the high speed flowing air.
Quick freeze cabinet, also named as instant freezer is suitable for a small scale capacity to rapid freeze French fries, meat, poultry, fruit, seafood etc.
As unfrozen fresh material is of different dimenstion, to make a quick freeze process is subject to various Individual Quick freezing methods.
Freezing is one of the oldest and most widely used methods of food preservation, which allows preservation of taste, texture, and nutritional value in foods better than any other method.
The rate of heat transfer from the freezing medium to the product is important in defining the freezing time of the product.
Our Individual Quick Freezing Equipment (IQF) includes quick freezer and rapid freezer.
Properly frozen foods maintain more of their original color, flavor and texture and generally more of their nutrients. Air blast freezers typically are operated at temperatures of -30 to -45°C with forced air velocities of 1.5–6.0 m s-1.
Quick freeze process is one old and mature technology of food preservation.
In the contact plate freezer, the product is pressed between metal plates (hollow shelves). Refrigerant is circulated inside channels in the plates, which ensures efficient heat transfer and results in short freezing times, as in the case of frozen fish fillets, shrimp, chopped spinach, or meat offal.
Spiral Quick Freeze Machine is suitable for frozen potato chips fries, banana/plantain chips vegetable chips manufacture.
Low installation space request, highly freezing efficiency and energy-saving are the most features.
Nominal capacity is 300kg/h ~ 6000kg/h.
