Object of this cleaner is to open and clean the cotton, but this cleaning unit introduces the idea of dirt separation from cotton by airforce.
The function of the Kirschner beater section is to open and clean the cotton and prepare the cotton for air jet section.
The tuft of cotton from the kirschner beater section is entered in to the aero dynamic constricting duct.
The air current from the booster fan carry the cotton toward the bend in the duct.
The duct makes a sharp turn of about 120 degree.
At this bend in the duct, the forward end is left open as a narrow, adjustable slot, about 3/4 of an inch (according to the trash present in cotton) for the discharge of trash.
The momentum of the trash and heavy waste is a greater force than the air current on it, so, trash particles are projected through this opening in the duct into the trash compartment,
The momentum of the cotton is a smaller force than the action of air current on it, so the good lint is drawn around the bend of the- duct and passes through the outlet pipe. Another high suction air current from condenser fan, suck the good lint only from the outlet pipe and is deposited on to the condenser of the subsequent machine.
