Advantages

Food-Grade Material & Hygiene Assurance

Core components in contact with materials are made of SUS304 stainless steel. The smooth, dead-corner-free surface is easy to clean and disinfect, effectively preventing material residue and bacterial growth, easily meeting strict GMP and HACCP certification requirements.

Fully Enclosed Conveying & Eco-Friendly

Featuring a unique fully enclosed conveying pipe design, it locks in dust from the source, preventing material spillage and dust pollution. This not only significantly reduces the loss of expensive powders but also creates a safe and clean working environment for employees.

Fully Automated Operation & Cost Efficiency

The equipment supports one-touch start and fully automated continuous operation with adjustable conveying speed and uniform flow. A single unit can replace 2-3 manual workers, significantly reducing labor costs and management complexity for enterprises.

Modular Design & Flexible Adaptation

Inlet and outlet positions can be customized with inclination angles based on site space, supporting horizontal, inclined, or vertical layouts. Requiring no foundation, the equipment is highly mobile and seamlessly integrates with upstream and downstream equipment like crushers, mixers, and packaging machines.

Frequently Asked Questions

Q1: What is the difference between a screw feeder and a vacuum feeder?

A screw feeder uses mechanical screw pushing, resulting in extremely low energy consumption (about one-third of a vacuum feeder) and no need for frequent filter cleaning. It is ideal for high-capacity, continuous powder/granule lifting. A vacuum feeder relies on negative pressure airflow, suitable for ultra-fine dust or short-distance, intermittent suction operations.

Q2: Can the equipment convey materials at any inclined angle?

Yes. The standard inclination angle is 45°, but we support customization between 30° and 60° depending on factory height and space constraints. Note that the steeper the angle, the more obvious the gravity fallback of the material, which will correspondingly reduce the actual conveying efficiency.

Q3: What should be done if the material is highly viscous and prone to blockage?

For viscous materials, we recommend the following measures: First, equip the hopper with a vibration motor to assist feeding through high-frequency vibration. Second, apply mirror polishing to the screw blades and inner walls to reduce the friction coefficient. Third, for materials extremely prone to wrapping, a shaftless screw feeder can be directly selected.
