Abstract

The article presents the research of kinetics and intensity of convective-radiation foam drying of gelatin broth from ordinary fish processing wastes in the Astrakhan region. Approximating dependences of dry gelatin removal from the unit area of the working surface per unit time on the varied factors have been obtained. The rational modes of the process, in which the maximum specific removal of the dry product is achieved, have been determined. It has been found that using only radiation energy supply makes the process of foaming gelatin broth difficult due to the uncontrolled sharp increase of temperature of the product and, as a consequence, the subsequent melting and destruction of the foam. Putting radiation energy supply into the process of convective foam drying of the gelatinized broth under rational conditions increases the specific productivity of the process by three times.
