grain destoner technical analysis and manufacturing specifications
Capacity: 2–10 tons per hour. After full seed plant cleaning, seed purity reaches 99.99%; the processing line removes impurities including dust, light impurities, leaves, shells, large and small impurities, stones, sand, bad seeds, and injured seeds. Delivery period is 30 working days, with certifications SGS, CE, and SONCAP.
Seed Processing Plant Introduction
For the seed processing line, our primary focus is to provide a complete process for cleaning, screening, grading and packaging a wide range of crop seeds (such as grain seeds, vegetable seeds, oilseed seeds, and more). This solution differs from conventional grain and legume cleaning lines. The key emphasis is on preserving germination rate, improving purity, and preventing damage, making it suitable for the large-scale and standardized production requirements of seed processing factories.
Capacity: 2000–10,000 kg per hour
It can process seeds including sesame, beans, groundnuts, and chia seeds.
The seed processing plant includes the following machines.
Pre-cleaner: 5TB-10C air screen cleaner
Clods removing: 5TBM-5 magnetic separator
Stones removing: TBDS-10 de-stoner
Bad seeds removing: 5TBG-8 gravity separator
Elevator system: TBE-10 elevator
Packing system: Auto packing machine
Dust collector system: Dust collector for each machine
Control system: Auto control cabinet for the entire seed processing plant
Each machine (overview)

Air screen cleaner
Designed to remove large and small impurities, dust, leaf, small seeds, and other contaminants.
Used as a pre-cleaner in the sesame processing line.

De-stoner machine
TBDS-10 de-stoner, blowing type.
The gravity de-stoner removes stones from sesame, beans, groundnuts, and rice with high performance.

Magnetic separator
Removes all metals, magnetic clods, and soil impurities from beans, sesame and other grains. Widely used in Africa and Europe.

Gravity separator
Removes blighted seeds, sprouted seeds, damaged seeds, injured seeds, rotten seeds, deteriorated seeds, and moldy seeds from sesame, beans and groundnuts with high performance.

Color sorter
As an intelligent machine, it detects and removes mildewed rice, white rice, broken rice, and foreign matters such as glass in the raw material. It also classifies rice by color.

Auto packing machine
Function: Used for automatic bag packing of beans, grains, sesame seeds, maize, and more. Bag size: 10–100 kg. Electronic-controlled automatic operation.
What Can the Seed Processing Plant Do?
Compatible crop seed categories: Grain seeds (wheat, corn, rice, sorghum, millet, etc.), vegetable seeds (cucumber, tomato, cabbage, chili, etc.), oilseed seeds (rapeseed, peanut, sesame, etc.), forage seeds, and other miscellaneous grain seeds for various crops.
