Stainless Steel Flour Screw Conveyor Feeding System

Product introduction of Stainless Steel Flour Screw Conveyor

The stainless steel flour screw conveyor is a high-efficiency food grade conveying equipment designed for transporting flour, sugar, and other fine powders between different processing stages or production floors. As a type of auger conveyor system, it uses a rotating spiral blade inside a closed tube to move materials continuously and safely.

Built with 316L stainless steel, this screw conveyor system ensures hygienic operation, corrosion resistance, and long service life, making it ideal for food processing, pharmaceutical, and chemical industries. It can be customized according to capacity, angle, and installation requirements, offering flexible integration into modern production lines.

Working principle

The screw conveyor operates through a rotating spiral blade inside a sealed stainless steel tube.

Step 1: Material Feeding
Flour or powder materials are fed into the inlet hopper.

Step 2: Spiral Rotation
The motor drives the screw shaft, rotating the spiral blade.

Step 3: Material Push Forward
The rotating blade pushes materials forward inside the casing.

Step 4: Continuous Conveying
Materials are continuously transported along the pipeline.

Step 5: Discharge Output
Powder materials are discharged evenly at the outlet end.

Step 6: Optional Vibration Assistance
Vibrator can be added to improve feeding speed and stability.
