Before undergoing deep processing (such as cocoa paste and cocoa powder), cocoa beans must first undergo efficient and precise cleaning and screening processes to ensure raw material purity and subsequent product quality.
Our cocoa bean cleaning line consists of a pre-cleaner, destoner, gravity separator, magnetic separator, and grader. It achieves a cleaning rate exceeding 99.8% and a stone removal rate surpassing 99.5%, effectively eliminating dust, stones, metallic impurities, defective beans, and insect-damaged particles.
The entire line features a rational structure and high automation, making it suitable for large-scale continuous production. It significantly reduces raw material loss, providing cocoa processing enterprises with a high-standard, high-value-added pre-processing solution.
Seed pre-cleaning machine
The 5XZC series pre-cleaning machine is widely used for cleaning and grading grains, seeds, and agricultural byproducts such as corn, wheat, rice, peanuts, soybeans, millet, sunflower seeds, melon seeds, grass seeds, spices, cocoa beans, pepper, and cumin.
This equipment efficiently removes light impurities and foreign matter of various sizes while performing screening and grading of materials, making it an indispensable core component in grain processing and seed treatment operations.
Main structure
The seed cleaner machine consists of a machine frame,elevator system,seeds distributed box,air screen, vibration sieve, dust collector, seed discharged outlet, and control cabinet.
Working principle
Raw materials enter through the feed hopper and are conveyed by the bucket elevator to the distribution box, where they are evenly distributed before entering the airflow screen.
- Airflow separation: within the airflow screen, lightweight impurities (dust, straw, chaff, etc.) are drawn away by the blower and discharged from the cyclone separator.
- Screening separation: the remaining material enters the vibrating screen box. Under the action of screens with different mesh sizes, large impurities, small impurities, and qualified seeds are discharged from their respective outlets.
By replacing screens of different specifications, the equipment can process various types of seeds and agricultural products, demonstrating strong adaptability.

Working principle
The destoner machine utilizes the density difference between grains and stones for separation. After raw materials enter the equipment:
- Airflow action: a high-precision multi-blade fan lifts lighter grains into suspension.
- Screen adhesion: heavier stones adhere tightly to the stainless steel screen.
- Vibration separation: by adjusting the vibration frequency of the workbench, stones and grains are thoroughly separated.
- Precision control: even when the density difference between stones and grains is minimal, variable frequency adjustment ensures highly efficient separation.

Working process
This machine achieves density separation of materials through the combined effects of airflow and vibrational friction:
- Raw materials are conveyed by an elevator into the gravity screen, where they are evenly distributed under vibration.
- Heavier materials (such as healthy, plump seeds) settle to the bottom layer and move upward due to friction on the screen surface.
- Lighter materials (e.g., insect-damaged, moldy, or shelled grains) are suspended by airflow at the surface layer and flow out along the lower section.
- Impurities (e.g., stones, sand particles) and inferior seeds are thoroughly separated, while qualified seeds are collected through a dedicated outlet.
Through this process, the gravity positive pressure density separator achieves efficient seed-impurity separation in a single operation. This ensures product quality, meeting the demands of large-scale production and high-standard seed processing.
