TQSF Gravity Destoner for Seed and Grain Processing

Product Overview

The TQSF Destoner is an advanced gravity separation machine designed for removing stones and other high-density impurities from seeds, grains and agricultural products.

Through the combined action of vibration, airflow and inclined screen surface, the machine separates materials according to density differences.

It effectively removes:

• Stones
• Glass particles
• Metal impurities
• Heavy foreign materials

while maintaining high-quality product output.

The TQSF series is widely used in seed processing plants, grain mills, coffee processing lines and food production industries.

Key Features

High-Efficiency Gravity Separation

The TQSF Destoner uses the difference in specific gravity between materials and impurities to achieve accurate separation.

It efficiently removes heavy impurities that cannot be removed by ordinary cleaning equipment.

Adjustable Airflow and Vibration System

The airflow volume and vibration parameters can be adjusted according to different raw materials.

This ensures stable separation performance for various seeds, grains and agricultural products.

High Processing Capacity

The TQSF series provides multiple models to meet different production requirements.

It is suitable for both small processing plants and large industrial production lines.

Stable Structure and Easy Maintenance

The machine adopts a strong steel structure with reliable operation.

The simple design allows convenient maintenance and reduces downtime.

Wide Application Range

Suitable materials include:

• Coffee beans
• Wheat
• Rice
• Corn
• Soybeans
• Sesame
• Vegetable seeds
• Other granular products

Working Principle

Raw materials enter the destoner evenly through the feeding system.

Under vibration and airflow action, materials are layered according to density.

Heavy materials such as stones move upward and are discharged separately, while lighter clean products move toward the outlet.

This process achieves efficient removal of heavy impurities.

Applications

The TQSF Destoner can be installed in:

✔ Seed processing lines
✔ Grain cleaning plants
✔ Coffee processing factories
✔ Food processing industries

Integrated with:

• Rotary Pre Cleaner
• Vibration Cleaner
• Aspirator
• Magnetic Separator
• Gravity Separator
• Color Sorter
• Bucket Elevator
