A model and method are suggested for calculating the 
cooling and freezing of a rectangular block of fish as applied to 
rotory freezing units. A Fourier dimensionless heat-conduction equation 
is formulated with allowance for the variable character of the thermophysical 
properties of the object to be frozen. The presented results of the 
calculation carried out by the finite-difference method are in agreement 
with the experimental data.
