Cooling tunnels are used to reduce the temperature of the confectionery and bakery products before packaging. This type of equipment is used mainly for the small products, the cooling time which is not more than 25 minutes. For longer cooling time it is advisable to install a spiral conveyor with air conditioner.
Construction parameters are calculated based on the customer's specifications, which should include the following information:
According with received information we will calculate parameters of the cooling tunnel:
The construction of cooling tunnel is a conveyor with modular belt which gets through the airways of conditioner. In the airways circulate cold air in a closed circuit. Air direction is opposite to the direction of the conveyor movement, that provides a more intense product cooling . Return air flow in the opposite direction occurs in the heat exchanger through the lower part of the airway. After getting through the heat exchanger cooled air is supplied to the area of product movement.
Typically, the cooling tunnel is installed as a part of automatic production line, that allows except the manual labor. For the linkage of the tunnel with other technological and packaging equipment are used various conveyors with PVC or modular belt, automation units, etc. Selection of the optimal configuration of the equipment depends on many parameters and is individually for each task.
