It only requires operators to place products to be cleaned on the feeding conveyor line and take them away from the unloading conveyor line. The automatic cleaning efficiency can reach manual wiping It improves the automation degree of production and speeds up the production progress. At the same time, it improves the efficiency and quality of automatic surface wiping and cleaning, effectively guarantees the yield rate of products, and eliminates the potential threat to human health caused by the original production. , Promote safe production, with advanced, efficient, environmentally friendly and energy-saving surface automatic wiping and cleaning equipment.
