Abstract
In most of conventional ice making systems, ice formation rate reduces with increase in thickness of ice formed on a cooling surface, and since some sort of external force or heat is required to remove ice from the cooling surface, ice formation and recovery of the formed ice cannot be simultaneously carried out. Thus, to solve the above problems simultaneously, new continuous ice making system using a metallic belt with a forward constant velocity was proposed and its ice making characteristics were clarified. However, in the case of the forward constant belt velocity, the belt velocity must be decreased to extend a contact time between the cooling block and belt. In this paper, to extend the contact time without decreasing in the belt velocity, ice was continuously made, moving die belt in the forward and reverse directions under the fixed period. And at that time, the contact thermal resistance between the cooling block and belt was investigated and its ice making characteristics were clarified.
