CSA Xpert

It is a power operated machine to clean threshed paddy crop. The machine is made of mild steel and consists of a blower, an electric motor (1 hp), hopper, vibratory feeding tray, discharge chute with two screens (top scalping and bottom grading screen) and supporting frame with trolley wheels. The blower is of centrifugal type with long axis and straight blades. The hopper is truncated trapezoidal in shape opening on to the vibrating tray. An adjustable gate at the bottom opening of the hopper controls the feed rate of impure grain. The vibrating tray is hinged with the main frame at slight inclination. Thick wire strips are welded like teeth of a comb at the lower end of the tray. One top scalping screen having slotted holes (2.8x19 mm) and one bottom grading screen having round holes (1.8 mm) are provided in this discharge chute for cleaning operation. A damper is provided along the chute to obstruct the airflow to prevent good grains blowing away with chaffs. The whole unit is mounted on trolley wheels along with a handle to make it movable.
