Sanitary Semi-Automatic Powder Hopper
The Semi-Automatic Powder Hopper is a specialized stainless steel vessel designed for controlled dosing and discharge of powder and granular materials in sanitary processing environments. The conical bottom design ensures smooth material flow and minimizes residual buildup. This hopper is engineered to meet the stringent hygiene requirements of the food beverage pharmaceutical and cosmetic industries. All product contact surfaces are polished to a sanitary finish to prevent bacterial contamination and facilitate thorough cleaning between batches.
