Product Overview

The Gravity Separator is a high-performance separation machine designed for coffee bean cleaning and quality improvement. It uses the difference in specific gravity, particle size and aerodynamic characteristics of materials to separate high-quality coffee beans from lightweight impurities, immature beans and damaged products.

During coffee processing, the gravity separator can effectively improve the uniformity and quality of green coffee beans before roasting or further processing. It is widely used in automatic coffee processing lines together with cleaning machines, destoners, graders and color sorters.

With advanced vibration technology, adjustable airflow system and reliable structure, the gravity separator provides accurate separation, stable performance and high processing efficiency.

Key Features

Precise Separation Based on Specific Gravity Difference

The gravity separator separates materials according to density and weight differences.

It can effectively remove:

• Empty coffee beans
• Lightweight beans
• Immature beans
• Broken materials
• Dust and impurities

This improves the quality and consistency of coffee beans before roasting.

Adjustable Airflow and Vibration System

The machine adopts an adjustable airflow system combined with vibration movement to achieve accurate material separation.

Operators can adjust airflow volume, vibration frequency and deck angle according to different coffee bean varieties and processing requirements.

High Efficiency and Stable Operation

The optimized structure ensures continuous feeding and stable discharge.

It is suitable for industrial coffee processing plants requiring high capacity and consistent product quality.

Food-Grade Construction and Easy Maintenance

The machine adopts high-quality materials with a durable structure.

The simple design makes operation, cleaning and maintenance convenient, reducing downtime during production.

Flexible Application in Coffee Processing Lines

The gravity separator can be integrated with:

• Coffee Bean Cleaning Machine
• Coffee Bean Destoner
• Coffee Bean Magnetic Separator
• Coffee Bean Grading Machine
• Coffee Bean Color Sorter
• Coffee Roaster

It is an ideal solution for complete coffee processing plants.

Working Principle

The coffee beans enter the vibrating separation deck evenly.

Under the combined action of vibration and airflow, materials are stratified according to different specific gravity.

Heavy and high-quality coffee beans move upward and discharge separately, while lightweight materials and impurities move in another direction.

This process achieves accurate separation and improves final coffee quality.
