Screw Conveyor Feeder for Spice and Seasoning Processing

Product introduction of Screw Conveyor Feeder

The Screw Conveyor Feeder is an efficient automatic screw feeding solution designed for continuous transfer of granules, pellets, and dry powder materials in various industrial applications. It is widely used to move materials from the ground level to higher production equipment, such as packaging machines, filling machines, mixing machines, and processing systems.

With a stainless steel material contact structure, this screw conveyor feeder ensures hygienic operation and prevents contamination during transportation. The enclosed screw conveying design helps protect materials from external pollution while maintaining stable and controlled feeding performance.

Equipped with a large-capacity hopper, adjustable feeding control, mobile swivel casters, and a durable screw drive system, the machine offers convenient operation, easy movement, and reliable performance. It is suitable for food processing, plastic manufacturing, chemical production, pharmaceutical industries, and other applications requiring automatic granule feeding.

The conveyor helps reduce manual handling, improve production efficiency, and provide a safer and more consistent material feeding process.

Working principle

The Screw Conveyor Feeder uses a rotating screw shaft inside the conveying tube to move materials continuously from the hopper to the discharge outlet. When materials enter the hopper, the screw rotation pushes the granules forward and lifts them to the required height.

The feeding speed can be adjusted according to production requirements, ensuring stable material supply for downstream equipment. The enclosed conveying system reduces dust, prevents contamination, and provides a cleaner working environment.

The conveyor can be directly connected with packaging machines, filling machines, mixers, and production equipment to create an automated material feeding process.

Working Process

1. Material Loading

Materials such as granules, pellets, dry food ingredients, plastic particles, or other bulk materials are manually or automatically loaded into the large hopper.

2. Screw Conveying

After starting the machine, the motor drives the internal screw shaft to rotate. The rotating screw pushes materials forward inside the conveying tube and transports them continuously.

3. Inclined Lifting

The screw conveyor transfers materials from a lower position to a higher position through the inclined conveying tube, overcoming height differences between equipment.

4. Controlled Discharge

Materials are discharged smoothly through the outlet into connected equipment, such as packaging machines, filling machines, mixers, or processing systems.

5. Continuous Feeding

The conveyor maintains a stable material level in the receiving hopper, ensuring continuous production and reducing manual feeding requirements.

6. Cleaning and Maintenance

The reverse rotation function helps remove residual materials inside the conveyor, making cleaning and maintenance easier and improving operational reliability.
