Fluidized bed freezer

Fluidized bed freezer is best machine to realize fruit, vegetable and some seafood fluidization monomer, frozen goods move in the transmission belt, with increase of air velocity, the food layer begins to loose; When wind pressure reaches a certain value, food particles remain stationary state, no longer suspension part particles upward, bed expansion, void fraction increases and format fluidized bed; Fluidized bed body at this time is the strong cold wind blowing at the bottom of the food in the suspended state, frozen goods by air cooling flow around in all directions, to achieve rapid freezing of food after the formation of monomer, fast frozen food by cooling, surface freezing, deep freezing three phases, in order to gain the highest quality of frozen food.
The products are widely used in vegetables, fruits, fungi and granular, sheet, block of quick frozen food.

Technology Features:

Reliable transmission system

◆ The main driver provides all the driving forces necessary to run the conveyor belt around the support and operate the system. New type gear reducer with high efficiency and long service life.
◆ The auxiliary drive is generally used as a tensioning device, which controls the power transmission between the bracket and the conveyor belt, making the net belt run more stable.

High strength mesh belt,full stainless steel structure

◆ High strength mesh belt,full stainless steel structure
◆ Flat mesh belt surface, minimum belt mark on products.
◆ Side guards provide on the belt edge to prevent the products faling off the belt.
◆ Stainless steel sprocket of the conveyor system.

Insulated enclosure with two sided stainless steel skin plate

◆ Insulated enclosure made by the imported PU foaming machine. PU insulated enclosure with two sided stainless steel skin plate, double sealed door with door heater to prevent door from frozen.
◆ The toperator can access inside of spiral freezer to inspect the equipment any time.

Efficient and sanitary evaporator, optimum air flow pattern

◆ The evaporator is made of aluminum alloy or stainless steel. It is easy to clean and reduce the growth of bacteria.
◆ The design of the variation plate is large, the windward area is large, effectively prevent frost plug and prolong defrost time.
◆ The evaporator adopts the world's most advanced liquid supply method, and the heat exchange efficiency is more than 35% higher than the traditional one.
◆ The tube can be made of stainless steel.
◆ The freezing efficiency is thus improved, and the cold loss at the inlet is minimized.

ADF automatic air defrosting

◆ The air is compressed, dried and filtered to be injected into the energy storage tank by the pressure of 0.6-0.8 MPa.
◆ Mixer gases in storage tanks through electromagnetic valve opening and closing to enter the defrost header inside the quick-freezing machine, manifold nozzle for continuous defrosting of evaporator finned, really achieve the lower costs, continuous uninterrupted production.
