Abstract

When foods are frozen to preserve as well as perform the first stage during condition of freeze drying. The problem need to consider how to determine optimal freezing temperature, this problem is complicated. In this article presents research results of a mathematical model in describing freezing heat transfer to determine ice ratio of humid material following freezing temperature, the results received was basic to determine optimal freezing temperature, to regime technological the first stage of freeze drying and applied to calculate and design the system of freeze drying.
