How to use Yinda Amaranth Oil Cake Grinding Machine From Coarse to Fine Powder?
Amaranth oil cake, the valuable by-product obtained after amaranth seed oil extraction, is gaining increasing attention for its rich nutritional profile and functional applications in the food, supplement, and cosmetic industries. As the demand for fine amaranth oil cake powder continues to rise, selecting the right grinding machine becomes the key to achieving stable quality and desired particle sizes.
At YINDA Machinery, we provide professional grinding solutions for different powder fineness requirements, ensuring consistent output, easy operation, and minimized material loss.
Pre-treatment Condition — The Key to Stable Grinding
Before grinding, amaranth oil cake must undergo de-oiling and moisture control to ensure stable performance.
- Oil content: below 10–15%
- Moisture content: below 5–10%
Maintaining these limits prevents screen clogging, excessive heat generation, and agglomeration during grinding. Proper pre-treatment not only improves the final powder quality but also extends machine lifespan.

For 10–80 Mesh Powder — YDGS Series Hammer Mill with Cooling System
For coarse to medium powder sizes (10–80 mesh), we recommend the YDGS Series Hammer Mill combined with a wind-cooling system.
The YDGS Hammer Mill is specially designed for materials with moderate oil content. Its spacious grinding chamber allows efficient airflow, preventing material accumulation around the blades and screen. The high-speed rotating blades impact and shear the material into uniform granules, while the cooling airflow helps to reduce grinding temperature, ensuring no oil leakage or caking occurs.
Key Advantages:
- Suitable for semi-oily materials like amaranth oil cake, chili, turmeric, etc.
- Adjustable particle size by changing screen mesh.
- Easy cleaning and maintenance design.
- Continuous, stable operation with minimized downtime.

For 100–300 Mesh Fine Powder — YDWF Series ACM Mill with Cooling System
When finer powder (100–300 mesh) is required, the YDWF Series ACM Mill (Air Classifier Mill) becomes the ideal choice. This system integrates grinding and classification in one chamber, allowing precise control of the final particle size.
The working principle is based on high-speed airflow:
Material enters the grinding chamber, where the rotating pin disc and classifier wheel work together under controlled air pressure. The cooled airflow ensures low-temperature grinding, preventing the oil components in amaranth cake from melting or sticking.
Why low-temperature grinding matters:
*Preserves nutrients and active compounds in amaranth powder.
*Prevents oxidation or color change.
*Ensures uniform and fine powder texture for high-value products.
Main Features:
*Integrated classifier for precise particle control.
*Stable temperature management through cooling airflow.
*Suitable for food-grade, chemical, and cosmetic applications.

Recommended Auxiliary Equipment — YDLH Series Ribbon Blender
After grinding, the YDLH Series Ribbon Blender is recommended for homogeneous mixing of amaranth powder with other functional ingredients such as protein, fiber, or flavoring.
Its dual-layer ribbon structure ensures efficient blending in both radial and axial directions, achieving uniform powder mixtures within a short time — perfect for bulk powder blending and industrial production lines.
