Performance Analysis of Rotary Cotton Seed Dryer

Abstract

Drying is perhaps the oldest and most commonly used technique in the processing of the cottonseeds for extracting the cottonseed oil and cottonseed meal of good quality. The cotton seed contains about 17-18% of moisture by weight, and it must be dried only up to 6-7% of moisture inherent in it. For accomplishing the above purpose, the convective type of dryer is used. The dryer is named as 'Rotary Cotton Seed Dryer' For the enhancement of performance of the dryer, the effect of operating variables mass flow rate of air & inlet temperature of air on shrinkage ratio, specific energy consumption (SEC) and pickup efficiency are to be studied in this work. Keywords-Cotton seed dryer, humidifying efficiency and moisture content.
