As agricultural by-products gain importance in value-added processing, the fine grinding of peanut oil press cake (peanut press cake) is attracting increasing attention. Qingdao Clender Machinery Technology Co., Ltd. (CLENDER) offers ultrafine grinding equipment and process configuration support for customers seeking a finer and more consistent particle size from pressed cake materials.

Material properties come first

Peanut press cake may be dense and irregular in shape. Its residual oil content, moisture and fiber composition vary with the extraction process. Higher oil levels may cause sticking, agglomeration or unstable classification during grinding. For this reason, feed size, residual oil, moisture, target fineness and required capacity should all be reviewed before equipment selection.

Where residual oil is relatively high, possible options include pre-crushing, further defatting, cryogenic or other low-temperature grinding methods, depending on the material. Testing is recommended before any performance commitment.

A process tailored to production needs

Depending on material samples and production goals, CLENDER can assess an integrated arrangement covering feeding, grinding, classification, cyclone collection and dust filtration. Suitable process matching supports steadier operation and more consistent powder handling.

Subject to material quality, hygiene standards and local regulations, processed peanut press cake may be considered for feed ingredient processing and selected industrial formulations. End-use suitability must be verified independently.

Testing before final specifications

Customers are encouraged to share sample photos, residual oil percentage, moisture content, desired mesh size and hourly throughput. Trial grinding may be required to validate the proposed solution. Final fineness and capacity depend on material testing and mutually agreed technical specifications.

Qingdao Clender Machinery Technology Co., Ltd. provides powder-processing equipment and application support for food, feed and industrial materials, with an emphasis on matching systems to actual operating conditions.
