AMC food tunnel cooling device

AMC AMC 2015-07-24 14:48:56
Now commonly used cooling tunnel system for the inner chocolate, candy, cookies and other food manufacturing industries
Thermal processing is complete food for cooling stereotypes. Such a tunnel-type cooling device usually by a belt conveyor system, wind shell and
Evaporator composed of three parts, the belt conveyor device includes a belt round the belt and drive belt transmission mechanism operation, which
The belt is located inside the air guide housing. Air guide casing is usually separated by a pallet into upper and lower chambers, located on the pallet belt
Above. The wind on the housing, two chambers by opening lower end of the pallet of communicating, while separately by the two chambers
Delivery tube evaporator outlet and inlet connected In operation, the cold air generated by the evaporator through the first air guide housing
The upper chamber, and the blowing of the food is cooled from the surface of the food, and then go to the other side of the air guide housing bottom pallets back
Inside the evaporator, as the cycle.
However, the existing drawbacks of the tunnel-type cooling apparatus exists is: stream flows directly from the surface of the food too easy
Resulting in the surface shape of the food produce corrugated deformation, especially in setting requirements for high heat melt chocolate and confectionary food
Products, such foods are difficult to shape after deformation remedy and repair. On the other hand, conventional tunnel-type cooling device work
The airflow within the air guide housing unevenly distributed, with the heat exchange surface of the heat effect of the food is poor, the lower the cooling efficiency.
