A model for predicting freezing times of individual particles is adapted to operating conditions of fluidized beds. The equation is linked to a model for movement of solids along the continuous fluidized bed which includes longitudinal mixing. The equations obtained allow the design and optimization of fluidized bed freezers. Calculations are performed for beds of green peas. Maximum values in the production rate are found in terms of bed dimensions and operating conditions. A nomogram is provided to facilitate equipment design under conditions of maximum production rate and minimum blower power consumption.
