Abstract
A column of fast moving air with entrained seed cotton is jetted upward from a nozzle in the bottom of a fountain dryer. The column will remain intact until it hits the top of the fountain dryer. At the top, the column will disburse and the mixture of air with entrained cotton will return to the bottom of the dryer in an annulus between the column and the wall of the dryer. There will be an interface of the upward column with the downward annulus. The opposing flows will be roiled and cause turbulence at the interface between the upward column and the downward annulus. The rolling and turbulence will be increased along the walls of the vessel by structure which will reverse the direction of the downward flow of the cotton. The downward flow of the cotton is collected in an annular plenum surrounding the bottom of the column and is directed to an outlet duct. The outlet duct and the annular plenum with the inlet at the center thereof, form a banjo separator.
