| The tunnel quick freezer is a continuous freezing equipment using a unique air distribution device. According to the air distribution structure form, it can be divided into ordinary tunnel and high-efficiency collision type. According to the conveyor belt style, it can be divided into mesh belt type and plate belt type. | |||||||||
Features
Ordinary tunnels adopt the 'impact airflow' air distribution form. The cold air flows through the air distribution plate on the upper part of the conveyor belt and is accelerated into a vertical impact cold air flow, which continuously exchanges heat and cold for the frozen products to achieve the purpose of rapid freezing.
The efficient collision adopts the 'two-way air flow collision' air distribution form. There are air distribution plates on the upper and lower sides of the conveyor belt that simultaneously spray and collide the cold air flow to the surface of the frozen products to increase the heat conductivity, thereby shortening the freezing time and improving the quality of the frozen products.
Various styles of conveyor belts meet customers' needs for various products. The conveyor belts are made of special high-strength 304 stainless steel and run smoothly, complying with food safety.
Using well-known brand fans, 304 stainless steel frame and casing, aluminum alloy impeller, aluminum shell motor, high efficiency.
The insulated warehouse body is made of double-sided 304 stainless steel plates with a smooth and beautiful surface, polyurethane foaming technology, and good thermal insulation performance. The bottom warehouse board is fully welded with a ship trough and has a slope drainage ditch, which is waterproof and prevents cold penetration.
The interior of the thermal insulation warehouse adopts a wide channel design, making it easy for personnel to clean and repair, and it is hygienic and has no dead ends.
The evaporator adopts a variable blade pitch method, which can work efficiently and continuously for a long time.
The operation is simple and convenient, and it can realize one-click automatic start, multi-frozen product recipe preset, remote operation data collection and many other intelligent functions.
