Abstract

The present research was carried out to manufacture and evaluate the performance of a horizontal single-pass animal feed pellets cooler to improve product quality. The cooler performance was studied as a function of change in pellets feed rate, conveyor chain speed and airflow rate. Performance evaluation of the horizontal cooler was carried out in terms of final pellets moisture content, cooling efficiency, pellets durability, energy requirements and cooling cost.
The experimental results revealed that final pellets moisture content, cooling efficiency, pellets durability, energy requirements and cooling cost are in the optimum region under the following conditions:
-          Pellets feed rate of 2.2 Mg/h,
-          Conveyor chain speed of 2 cm/s,
-          Airflow rate of 12 m3/s.
