Customized Mini Screw Auger Feeder for Continuous Dosing, Stainless Steel Screw Feeding Machine for Food Powder and Plastic Pellets

This mini horizontal screw feeder is built with food-grade stainless steel and a variable speed motor. It delivers stable, quantitative feeding for flour, fine powder and plastic pellets. Its compact footprint, dust-tight design and easy disassembly make it ideal for small automated dosing, food processing and plastic production lines.

This horizontal screw feeder operates on the spiral pushing conveying principle. Powder or granular materials such as flour and plastic pellets fall into the square hopper by gravity. The variable-speed motor drives the built-in spiral screw to rotate continuously. As the screw blade rotates, materials are steadily pushed forward and discharged from the outlet. Feeding output is controlled by adjusting motor speed, achieving uniform and quantitative feeding. The compact enclosed hopper structure prevents dust escape and material splashing. The screw assembly can be detached quickly for internal residue cleaning and material switching, avoiding cross-contamination between different batches.

1. Hygienic stainless steel construction: The hopper and contact parts adopt 304 stainless steel, which is rust-resistant and corrosion-resistant, making it safe for food-grade materials like flour, milk powder and edible additives.
2. Stepless adjustable feeding speed: Equipped with a variable speed motor, users can flexibly adjust the feeding flow according to downstream process requirements, ensuring stable dosing for continuous production.
3. Compact space-saving design: The small overall size makes it easy to install and connect with mixers, extruders and packaging machines on limited-space workstations.
4. Dust-free enclosed conveying: The sealed feeding chamber effectively suppresses powder flying, reduces material waste and keeps the workshop clean.
5. Simple maintenance and operation: The machine comes with a power switch for easy start and stop. The quick disassembly structure allows fast cleaning after production.
6. Wide material adaptability: It handles free-flowing fine powder and small granules, including flour, starch, plastic pellets, masterbatch and other similar materials.

This mini automatic screw feeder is widely used in the food processing and plastic industries. In food production, it provides quantitative feeding of flour, starch, seasoning powder and cereal powder, matching dough mixers, food mixing machines and packaging equipment. In the plastic industry, it feeds plastic pellets, color masterbatch and powder additives into extruders and mixing units.

It can also be applied in chemical, new material and laboratory small-batch testing scenarios for powder dosing. It replaces manual feeding, greatly improves feeding consistency and production efficiency, and lowers labor cost.

Different from large industrial screw conveyors, this small model focuses on low-capacity precise feeding. It is an economical auxiliary feeding equipment for small factories, test lines and semi-automatic assembly lines. Customization of hopper size, screw length and discharge direction is available to fit your existing production setup.
