Patent ID: 8046877

Claim:
A cotton gin comprising a module feeder, a cotton dryer, an air conveyor receiving cotton clumps from the module feeder and delivering them to the dryer, a separator/cleaner downstream from the cotton dryer, and a plurality of gin stands receiving seed cotton from the separator, the cotton dryer comprising a conduit adapted to pass seed cotton therethrough, and an array of electromagnetic wave energy generators on the conduit producing an energy density in the range of two tenths to six kilowatts of energy per pound of seed cotton whereby leaves and stems are more efficiently removed from cotton seeds and lint in the separator/cleaner, the air conveyor including a first air lock upstream of the dryer allowing conveying air and cotton clumps to pass through the first air lock into the dryer and a second air lock downstream of the dryer allowing conveying air and cotton clumps to pass through the second air lock out of the dryer thereby preventing discharge of electromagnetic wave energy from the dryer, the first and second air locks comprising a housing haying a rotary array of wipers therein.
