ABSTRACT
The effectiveness of the seed-cotton tower drier comes from the utilization of large amounts of energy to heat and move large amounts of air. Rising energy costs make the tower drier increasingly more expensive to operate. It is becoming increasingly more important to find cheaper alternatives to the tower drier for drying of seed-cotton. Laboratory tests have shown that the fiber fraction of dispersed seed-cotton locks can be dried from over 20 to 6 percent moisture content when held stationary in a relatively low temperature air stream for 15 seconds. A hypothesis was formed that this drying response might be duplicated in a counterflow seed-cotton drier. Teats of an experimental drier system using 150 to 200 F air have shown that the lint fraction of 13 to 17. 5 percent seed-cotton moisture can be dried to 7.4 percent in 14 seconds.
