The brush washing machine is a food processing machine designed to clean potatoes, cassava, and other root crops by removing soil, dirt, and surface impurities through the action of rotating brushes and water. It typically consists of a feeding hopper, rotating brush rollers, water spray system, washing chamber, discharge outlet, and an electric motor. The machine is constructed from durable, corrosion-resistant materials to ensure hygienic operation and reliable performance in agricultural and food processing environments.

In operation, the potatoes or cassava are fed into the washing chamber where rotating brushes gently scrub their surfaces while water is continuously sprayed to loosen and wash away dirt and debris. The combined brushing and washing action thoroughly cleans the produce as it moves through the machine. The cleaned products are discharged through the outlet for further processing, packaging, or storage, while wastewater and removed impurities are drained away. Regular cleaning and maintenance of the brushes and water system help maintain high washing efficiency and product quality.
