Batch Type Daal Washer (200 to 500 kg capacity) is an essential pre-processing machine for any Daal Mill or Namkeen plant. It is designed to remove dust, chemical residues, and mud from the surface of various pulses like Moong, Chana, and Masoor.

For a batch of 500 kg, the machine is typically built as a heavy-duty cylindrical or rectangular tank with a specialized internal agitation system.

2. Working Mechanism

• Tumbling Action: A central horizontal shaft fitted with SS Paddles rotates at a slow, constant speed (approx. 40–60 RPM). This ensures the daal grains rub against each other, effectively "scrubbing" off the dirt without breaking the grain.
• Water Circulation: Fresh water enters from the top through a perforated pipe. The dirty water, containing mud and light impurities, is discharged through a large-diameter bottom valve or a side overflow weir.
• Tilting Discharge: Since 500 kg of wet daal is extremely heavy, these machines are equipped with a Mechanical Gear or Hydraulic Tilting system. This allows the operator to tilt the entire drum to empty the washed daal into a collection trolley.

3. Key Advantages for Large Batches

• Gearbox Drive: Uses a Reduction Gearbox (Helical or Worm type) to provide high torque. This allows the machine to start and rotate even when fully loaded with 500 kg of dense material.
• Hygienic Design: All parts in contact with water and daal are mirror-polished SS 304 to prevent rusting and bacterial buildup.
• Low Water Consumption: Modern washers are designed to clean the maximum amount of grain with minimum water by using high-pressure spray nozzles.
