Tubular Chain Conveyor Coffee Bean and Powder Transfer System

Tubular Chain Conveyor Product Introduction

Tubular Chain Conveyor is a flexible enclosed conveying solution designed for the continuous transportation of powder, granular, and bulk solid materials. The system uses a chain-driven disc conveying mechanism inside a sealed pipeline, allowing materials to move smoothly through horizontal, vertical, and complex three-dimensional routes.

Unlike traditional conveying equipment, the tubular chain conveyor provides gentle material handling with minimal product degradation. The low-speed conveying process reduces impact and friction, making it suitable for fragile materials such as food ingredients, grains, coffee beans, powders, and other sensitive products.

The fully enclosed pipeline structure prevents dust leakage, protects materials from external contamination, and helps maintain a cleaner production environment. The flexible design allows the conveyor to pass around existing equipment and fit into limited installation spaces, making it ideal for modern automated production lines.

The conveyor can handle a wide range of materials, including flour, sugar, starch, coffee powder, cereals, pellets, chemical powders, fertilizers, minerals, plastics, and pharmaceutical ingredients. Depending on material characteristics and application requirements, different chain, disc, and pipe configurations can be selected to achieve efficient and reliable conveying performance.

Working principle

The Tubular Chain Conveyor operates through a continuous chain-and-disc conveying mechanism installed inside a sealed tube.

When the drive system starts, the chain moves continuously through the pipeline. Discs mounted at regular intervals on the chain push the material forward while maintaining a controlled conveying speed.

The flexible chain structure works like multiple universal joints, allowing the conveyor to change direction and move materials through horizontal, vertical, and curved sections without additional transfer equipment.

After reaching the required discharge point, materials are released through the outlet and transferred to the next processing stage.

This continuous enclosed conveying process helps reduce dust generation, prevent material loss, and maintain stable product quality during transportation.

Main Features

Fully Enclosed Conveying Structure

The sealed pipeline design prevents material leakage and external contamination while minimizing dust emissions. It is especially suitable for industries requiring clean and hygienic material transportation.

Gentle Material Handling

The chain and disc conveying method moves materials smoothly at low speed, reducing crushing, breakage, and segregation of fragile products.

Flexible Three-Dimensional Conveying

The conveyor can transport materials horizontally, vertically, and around obstacles with multiple bends, making it suitable for complex factory layouts.

Compact Space-Saving Design

The low-profile structure requires less installation space and can be integrated into existing production equipment where traditional conveyors may not be suitable.

Wide Material Compatibility

The system can handle powders, granules, pellets, and bulk materials, including food ingredients, chemical materials, agricultural products, and industrial powders.

Low Energy Consumption

Compared with pneumatic conveying systems, the tubular chain conveyor requires less energy and provides lower operating costs through efficient mechanical transportation.

Reduced Material Damage

The controlled conveying speed and enclosed structure help maintain material integrity, making it suitable for fragile and valuable products.

Dust-Free Operation

The closed conveying path reduces airborne particles and improves workplace cleanliness and safety.

Flexible Chain and Disc Options

Different chain and disc materials can be selected according to material characteristics, temperature requirements, wear resistance, and sanitation standards.

Easy Maintenance

The tensioning mechanism helps maintain proper chain operation, reduce wear, and extend equipment service life.
