Used Tunnel Equipment
A freeze tunnel is a process where the materials to be frozen are placed on an endless conveyor and passed through the tunnel where the refrigerants are used to cool the air and through circulation allow the material to become frozen. Other variations of the freeze tunnel process are the direct immersion tunnel systems where the refrigeration media is sprayed onto the product. This is a cryogenic freeze tunnel. A final variation of the freeze tunnel process is a quiescently frozen process for freezing materials in molds such as frozen ices in cups or forms and frozen in that shape and removed upon freezing for final wrapping. The refrigerants can be either chiller brines or cryogenic gases for achieving the required degree of freezing.
