Oil is tightly trapped inside the cell walls of plant cells. Ordinary crushing cannot open this “cage,” leaving the oil difficult to release.
Suitable for oilseeds such as soybeans and cottonseed. The oilseed material is rolled into uniform thin flakes of 0.3–0.5 mm, greatly increasing the surface area for solvent penetration and shortening the diffusion distance during solvent extraction.

Especially suitable for high-enzyme or high-fiber raw materials like rice bran and soybeans. Using instant high temperature and high pressure, the material is expanded into a porous “popcorn-like” structure. This not only inactivates lipase and other harmful enzymes but also creates countless microscopic channels for the solvent in the extraction plant.

The oilseed pretreatment stage largely determines the final extraction efficiency. The core lies in how thoroughly the cell-level disruption is achieved.
QIE’s intelligent flaking mill and extruder precisely control flake thickness and expansion degree, ensuring that the residual oil rate in the post-extraction meal is consistently controlled below 0.5%.
