How IQF fluidization tunnel freezer works
Date:
2023-03-22
The IQF fluidization tunnel freezer uses mechanical vibration and wind pressure to make the product float and run on the stainless steel mesh belt, so as to realize the rapid freezing of the monomer and prevent adhesion. It is mainly suitable for quick freezing of vegetables, fruits and other granular, flake and block foods.

It is mainly suitable for quick freezing of vegetables, fruits and other granular, flake and block foods.
IQF fluidization tunnel freezer is a processing method for preserving vegetables in a low-temperature quick-freezing method. After quick-freezing the pre-treated vegetables at a temperature of -30～-35°C or lower, they are packaged in plastic bags, boxes and other containers, or after packaging. Quick-frozen again, and then stored at -18°C to inhibit the growth and reproduction of microorganisms and the activity of enzymes, so that vegetables can be preserved for a long time.
The IQF fluidization tunnel freezer design process structural parameters for the characteristics of quick-freezing frozen products, super large effective surface area; monomer quick-freezing is not sticky, the difference between the evaporation temperature and the temperature in the quick-freezing room is reduced, and the defrosting cycle is extended, which fully meets the requirements; the temperature in the warehouse is -35 ℃ The principle of the fluidized bed with air blowing under the tunnel and the vibration device in the surface freezing section make the frozen products drop from +15°C to -18°C under the joint action of suspension and frequency conversion conveyor belt, uniform and rapid monomer freezing, and shipment Automatic blanking. The organic combination of evaporator, fan, air guiding device, and vibration device forms a uniform and stable suspension of frozen products and a negative feedback fluidized bed that is multi-directional to the individual wind, so that the frozen products can be frozen more quickly and with uniform quality.
