A numerical method for calculating the spherical products freezing time
Annotation
The article describes the difficulties in calculating the freezing time of spherical products by analytical methods, as well as the problem of determining the temperature field of frozen products at different stages of the process. A method of freezing spherical products by applying a numerical method of elementary heat balances is suggested. In this article the mathematical model of the numerical method and the algorithm is determining the freezing time is provided. There is the quantitative evaluation of the problem which is related to uneven heat load distribution on the evaporator system of fluidizing apparatus during continuous technological process. There are variants of a more evenly heat load distributing along the freezers given in the article.
