DWB Series Brush De-Awner Machine – Gentle Seed Cleaning & De-Awning Equipment
The MMCTECH DWB Series Brush De-Awner Machine is a specialized seed cleaning and de-awning solution designed to gently remove husks, awns, hairy tails, double grasses, loose fibers, and surface impurities from delicate seeds. Available in DWB-1501, DWB-1502, DWB-1503, and DWB-1504 models, this machine is engineered for commercial seed processors, grass seed cleaning plants, clover seed facilities, oat processing lines, forage seed operations, and specialty seed conditioning plants worldwide.
As a high-performance brush de-awner machine and seed cleaning machine, the DWB Series uses rotating brush cylinders, interchangeable mesh baskets, controlled product movement, and optional aspiration support to improve seed purity without damaging the seed surface. This makes it especially valuable for sensitive products such as clover, oats, grass seeds, forage seeds, alfalfa, ryegrass, fescue, pasture seeds, cover crop seeds, and other fine or delicate agricultural products that require gentle mechanical action before grading, sorting, packaging, or storage.
Precision Seed Cleaning for Delicate De-Awning Applications
Seed de-awning is an important process in seed conditioning. Many crops contain husks, awns, hairy tails, attached fibers, or surface materials that can reduce product flowability, interfere with grading accuracy, increase dust levels, and lower final seed quality. The MMCTECH DWB Series Brush De-Awner Machine is designed to solve these challenges by using a controlled brushing system that removes unwanted surface material while protecting valuable seed lots.
The machine is built for facilities that require consistent cleaning performance, reliable operation, and flexible processing capability. Whether used as a standalone seed de-awner or integrated into a complete MMCTECH seed processing line, the DWB Series supports higher-quality output and improved downstream processing efficiency.
Why Choose the MMCTECH DWB Series Brush De-Awner?
The DWB Series is engineered for precision, durability, and efficient seed processing. Its modular design allows different model configurations depending on the required capacity, number of brush cylinders, and product type. Interchangeable baskets and adjustable settings help operators fine-tune the machine for various seeds and impurity conditions.

How the DWB Series Brush De-Awner Machine Works
The product enters the brushing chamber where it is distributed into the cylinder section. Inside the machine, rotating brushes gently rub the seed against the selected mesh basket. This controlled action removes attached husks, awns, hairy tails, loose fibers, and surface impurities. The machine can be configured according to crop type, seed sensitivity, and cleaning intensity requirements.
After brushing, the cleaned product is discharged for further processing. When connected with aspiration or dust collection equipment, loose husks, dust, and fine particles can be removed from the process stream, creating a cleaner working environment and improving final seed quality.
Step-by-Step Seed Cleaning Process
- Step 1 – Seed Input: Seeds enter the brushing chamber through the inlet system.
- Step 2 – Brush Action: Rotating brushes gently remove hairy tails, husks, and surface impurities.
- Step 3 – Mesh Basket Contact: Seeds pass through the selected mesh basket for precise cleaning and de-awning.
- Step 4 – Dust Removal: Optional aspiration support helps remove loose dust and fine particles.
- Step 5 – Final Discharge: Cleaned seeds exit the machine for grading, sorting, packaging, or storage.
