preliminary cleaning
Keywords:
Corn germ is fed into a permanent-magnet drum to remove iron impurities, then passes through a primary cleaning screen that eliminates straw, large debris, and dust. Next, it enters a crusher for size reduction. The resulting granular material is transferred to a conditioning pot, where its moisture content is adjusted to the optimal level before being sent to the first and second oil-extraction presses. The cake from the second press is conveyed via equipment directly to the cake storage bin. Meanwhile, the oil and residue are separated using an oil-residue scraper system, with the oil flowing into a clarifying tank for sedimentation. After the sediment is removed, the residue is returned to the oil press for additional extraction. Meanwhile, the clarified oil overflows into a crude oil tank, where it’s pumped to a filter for further purification. Finally, the filtered crude oil is transferred by pump to the refining workshop for final processing and refinement.
