For preservation methods, freezing is the most effective preservation method, saving the most cost. For fresh food processors, this is the most important issue. Have you ever seen frozen lines in your factory, so you know how to preserve this?
The IQF refrigeration system uses special capacities based on products placed on the conveyor belt, moving at a slow rate in which it is exposed to cold temperatures and air at low temperatures. The origin is very fast.
In the IQF system, the product is moved on flat conveyor belts made of stainless steel material. Thousands of rays and cold air at ultra-high speeds blow directly and continuously to the top of the product and the underside of the conveyor, along with the high thermal conductivity of the conveyor used, quickly chill the product. . Two methods are convection heat exchangers and contactors.
Air flow contact around the surface of the product continuously so that the product quickly and evenly surface surface from the beginning of the winter room, thereby reducing the loss of water and loss of products. The quality of finished products has the optimum value for high economic efficiency.
Structure
The IQF conveyor belt system is equipped with one or two adjustable conveyor belts, depending on the freezing requirements of many different products. The indoor unit is arranged in two rows of two conveyors. The air duct system uses stainless steel material to direct the air toward the product onto the conveyor.
The conveyor system is very simple, the speed of the tape can change for each type of frozen products. Conveyor speed is controlled by a frequency converter, speed is from 0.5 to 10 m / min, freezing time from 0.5 minutes to 10 minutes.
Refrigerated freeze chamber made of polyurethane thickness 150 to 200mm, two sides are stainless steel, coated plastic food white on two sides.
Conveyor belt and equipment made of stainless steel. In this stainless steel indoor unit, the aluminum radiator grille is designed for NH3 / R22 circulation pump. Stainless steel mesh conveyor.
Working Principle
As the product moves through the freezing chamber on the conveyor belt, thousands of chillers of high speed air flow directly and continuously onto the product, blowing hot air around the product to push the heat exchanger at a rapid rate. Best.
As the cold air rays blow onto the product surface, the surface quickly forms a thin layer of ice that surrounds the product, reducing dehydration and keeping the product intact. The initial shape and size of the product is maintained during the freezing process.
Advantages of freezing conveyor systems
Limit water entering the insulated area by the 125 mm thick PU insulation. Medium trough designed for water spraying, cleaning and defrosting.
The transmission has automatic conveyor mechanism.
The diaphragm is made of silicone material, ensuring elasticity when subjected to cold temperatures and to ensure the requirements of food hygiene and safety.
The conveyor belt laths are made of plastic bars, ensuring frictional friction with conveyor belts, operating efficiently and with longer service life.
Fully automated control system, programmed according to the requirements of type and size of materials.
The radiator of the cooler design activities for 16 hours continuous upward defrost.
Cooling fan for high wind pressure is used in cold and humid conditions.
Products are frozen evenly, less loss, significant savings in power consumption.
