About Ss Screw Blancher

SS Screw Blancher Description

The SS Screw Blancher is an industrial food processing machine designed for blanching vegetables, fruits, and other suitable food products using controlled hot water or steam treatment. It uses a rotating screw conveyor mechanism to move the product through the blanching chamber at a controlled speed, ensuring uniform heat exposure and consistent processing. The machine helps inactivate enzymes, preserve product colour, reduce surface microbial load, and prepare food materials for further processing, freezing, drying, or packaging.

Manufactured with a robust stainless-steel construction, the SS Screw Blancher is suitable for food processing plants that require hygienic operation, efficient product handling, and reliable continuous production. The machine typically consists of a stainless-steel blanching tank, screw conveyor, drive motor, gearbox, heating arrangement, inlet and discharge sections, and supporting frame. Depending on the process requirements, it can be equipped with hot water circulation, steam heating, temperature control, drainage arrangements, and an electrical control panel.

During operation, raw vegetables or other suitable food products are fed into the machine through the inlet section. The rotating screw gently transports the material through the blanching chamber while maintaining the required residence time and processing temperature. After blanching, the product is discharged for subsequent operations such as cooling, dewatering, cutting, drying, freezing, or packaging. The screw conveyor helps maintain a steady product flow and supports consistent treatment across the processing line.

The SS Screw Blancher can be customized according to the type of food product, required production capacity, blanching temperature, residence time, and heating method. Food-contact parts can be manufactured using suitable grades of stainless steel, such as SS304, with SS316 options where the application requires enhanced corrosion resistance. Its practical design supports convenient cleaning, routine maintenance, and integration with other food processing equipment.
