Cocoa Bean Cleaning Line

The cocoa bean cleaning line is a high-efficiency automated system designed for cocoa processing. It can remove impurities and dust, separate stones, perform density screening, magnetic separation, and grading, preparing the beans for further processing.

With efficient machine layout and high performance, Taizy can achieve a 99.9% impurity removal rate, eliminating stones, dust, and moldy beans.

This production line processes 4–5 tons of cocoa beans per hour, greatly improving production efficiency. Customized solutions are also available—feel free to contact us.

Cocoa Bean Cleaning and Sorting Process

This cocoa bean cleaning line has five main steps: pre-cleaning and dust removal, stone removal, density-based separation of bad beans and moldy beans, magnetic separation, and grading. Each step is carefully designed to remove impurities like dust, stones, leaves, and light husks, improving the purity and quality of the cocoa beans. Here is a brief description of each step:

• Pre-cleaning and Dust Removal: Raw cocoa beans first enter the pre-cleaning system. Air and screens remove dust, leaves, light husks, and small debris, providing a clean base for the next processes.
• Stone Removal: Using density separation, stones, sand, and other heavy impurities are removed, protecting the equipment and improving the product’s purity.
• Density-based Sorting: With air pressure and vibration, moldy, insect-damaged, and immature beans are separated from healthy beans, ensuring stable product quality.
• Magnetic Separation: High-strength magnets remove iron filings, nails, and other metal impurities, ensuring food safety and safe equipment operation.
• Grading: Finally, a multi-layer vibrating screen grades the cocoa beans by size, ensuring uniform distribution for baking and grinding.

Cocoa Bean Cleaning Line Structure

This production line mainly consists of five core machines: the cocoa bean pre-cleaner, stone remover, density separator, magnetic separator, and grader. Below is a detailed introduction to each.

Cocoa Bean Pre-Cleaner – Dust and Impurity Removal

Функция

This machine removes dust, husks, small fragments, and other light impurities from cocoa beans, while also screening out large and small debris for initial cleaning and grading. It is suitable for cocoa beans as well as various grains and seeds in pre-processing.

Working Principle

The raw material is lifted into the distribution box and evenly falls into the air separation chamber. Airflow carries away light impurities, which are collected by a cyclone dust collector. The remaining beans pass through a vibrating screen, where different mesh sizes separate large debris, small debris, and clean beans. By changing the screen, the machine can process different types of materials.

Cocoa Bean Stone Remover – Removing Stones and Particles

Функция

The QSC-10 stone remover is used for cocoa beans, sesame, beans, corn, coffee beans, and other seeds to remove stones and soil. It can separate stones similar in size to the raw material, achieving up to 99.5% stone removal, ensuring clean raw material and improving the quality of subsequent processing.

Working Principle

Separation is based on the density difference between the beans and stones. Lightweight cocoa beans are suspended by airflow, while heavier stones stay on the stainless steel screen. The vibration table and airflow are finely adjusted, allowing efficient separation even when the density difference is small. Adjustable frequency allows precise tuning for different materials, ensuring effective stone removal.

Cocoa Bean Density Separator – Premium Bean Selection

Функция

The 5XZ-8 density separator is used for precise sorting of cocoa beans and various seeds. It removes low-quality beans, insect-damaged beans, moldy beans, beans with shells, stones, and other impurities. After processing, the beans’ thousand-grain weight, germination rate, cleanliness, and uniformity are greatly improved. The machine is flexible, easy to operate, portable, and reliable.

Working Principle

Raw material is fed into the gravity sorting table by a lifting machine. Seven adjustable air chambers and a vibrating table use air suspension and vibration to separate low-quality particles from good beans. The circulation sorting system further improves cleanliness, achieving over 99.8% sorting accuracy. Vibration frequency and air pressure can be finely adjusted for different materials, suitable for both large and small seeds.

Cocoa Bean Magnetic Separator – Removing Metal

Функция

The 5CX-5 magnetic separator efficiently removes metal impurities and magnetic foreign objects from cocoa beans and other grains or seeds. It ensures raw material safety and cleanliness while protecting downstream equipment.

Working Principle

The material passes through magnetic rollers and a conveyor into a strong enclosed magnetic field. Metals and magnetic impurities respond differently from seeds, allowing separation. The magnetic roller has a strength of 18,000 Gauss and a width of 1,300 mm, ensuring high capacity and efficient separation. Drum speed can be adjusted with a frequency converter to handle different seed sizes.

Cocoa Bean Grader – Size Classification

Функция

The grader precisely sorts cocoa beans by size. Using multi-layer adjustable vibrating screens, beans are classified by length, width, or thickness, ensuring consistency and quality for further processing.

Working Principle

Cocoa beans pass through multiple layers of vibrating screens. The mesh size can be adjusted according to customer needs, allowing beans of different sizes to exit from different layers for high-precision grading.

Applications of Cocoa Bean Cleaning and Sorting Line

• Cocoa Processing Plants: Perform preliminary cleaning and grading to improve roasting and grinding efficiency.
• Food Raw Material Workshops: Clean and sort coffee beans, nuts, beans, and similar granular food materials.
• Cocoa Export Companies: Ensure cocoa beans meet export quality standards through thorough cleaning.
• Agricultural Cooperatives or Farms: Pre-process self-produced cocoa beans to increase their value.
• Trade and Logistics Centers: Quickly clean large volumes of imported or exported cocoa beans, reducing impurities during transport.
• Other Granular Material Processing: Can also be used for cleaning and grading coffee beans, peanuts, corn, grains, and similar materials.
