The closed circuit aspirator type KTH is a cleaning machine that separates light impurities found in cereals. The machine may be divided into three main components:
Vibrating box: this is a feeding box attached to the machine body by six rubber mounts and vibrated by a motorized
vibrator.
- Body: in its upper part it houses 2 impellers driven by an electric motor and in its lower part it houses a waste products discharge
screw connected to a air lock seal.
- Outlet hopper: this is fixed to the lower part of the machine body.
Via gravity spouting the product enters into the vibrating inlet box and is forwarded and distributed thanks to the vibratory
motion and the particular configuration of the
internal product distribution blades.
During its fall into the hopper beneath an air stream passes through the product flow for separating light parts (waste product). Suction is produced by the negative pressure generated by the two impellers housed in the top section.
Aspirated waste is dragged by the air stream into a decantation zone, from where it falls and a collection screw conveyor
takes it to a sealed airlock valve. At its outlet the waste is fed directly to the offal spouting. The machine is provided with an air bleed for partial air recirculation and for maintaining inside the
condition of negative pressure.
