Abstract

The purpose of this paper is to study the operational thermal efficiency of the rotary flash drying equipment when it is used for drying fishmeal, to study the time for fishmeal to reach below the specified moisture and the drying rate of the rotary flash drying equipment under different temperature conditions, and to study the effect of the rising drying temperature on the main nutrients of fishmeal. The results showed that the thermal efficiency of the dryer gradually increased with the increase of drying temperature, the time required for drying became shorter, and the percentage of energy required for heating air and fishmeal warming decreased. However, the quality of fishmeal deteriorated with the increase of temperature. According to the operating parameters measured in the drying process, it is calculated that the drying temperature of 110℃ can meet the quality of finished fishmeal products and ensure that the drying thermal efficiency is maximized.
