This machine is a spray-type washer, consists of a horizontal conveyor, chain-link wire mesh, which it is a sprayed from all angles (including below) with high pressure water jets. the speed of conveyor can be varied from 1.5 to 6.0 m/s using a 1/2 hp electric motor and variable speed control gearnbox. Nozzles are fixed on 4 boom line 65 with the direction of chain conveyor, during the operation each boom will swing back and forth with the degree of 70. This ginger washer has a capacity of 1 ton/hr, the water consumption is 140-150 lit/min at 100-300 psi. The washed ginger, then put in the plastic buskets and eliminate water using the designed spinner. This spinner. This spinner. has a capacity of 80 kg in 1 minute for one batch (4 buskets) using a 1 hp electric motor and the angular velocity of 115 rpm. The dryer was designed for exported ginger, which is a tunnel dryer using heated air. This machine consists of a horizontal converyor which carries ginger through a tunnel in which heated air is forced in counter direction and has a capacity of 900-1300 kg/hr.
