Soybean Oil Processing Plan


After passing through a permanent magnet cylinder to remove iron impurities, the soybeans are fed into a cleaning screen, where they undergo further separation to eliminate straw, large debris, and dust. Next, a destoner removes any remaining stones before the material is sent to a crusher for size reduction. Once crushed into fine particles, the material moves into a conditioning tank, where its moisture content is adjusted to the optimal level. The conditioned material then proceeds to the first and second pressing stages of the oil-extraction machine. The resulting oil cakes from the second press are conveyed via equipment directly into the cake storage facility. Meanwhile, the oil and spent meal are separated using an oil-mill residue scraper system, with the oil flowing into a clarifying tank for sedimentation. After the sediment is removed, the remaining meal is returned to the oil-extraction machine for a secondary pressing cycle. Meanwhile, the clarified oil overflows into a crude oil tank, where it’s pumped through an oil filter. Finally, the filtered crude oil is transferred to the refining workshop for further purification and processing.

Corn Germ Processing Plan


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.

Walnut Processing Plan


Walnuts (with shells) are fed into a permanent-magnet drum to remove iron impurities, then pass through a cleaning screen that eliminates straw, large debris, and dust. They are subsequently packed into woven bags before being sent to a crusher for grinding. The resulting crushed particles are directly pressed in an oil-extraction machine, and the resulting oil cake is conveyed via equipment to a storage bin. Meanwhile, the separated oil and residue are processed further: the oil-residue mixture flows into a settling tank equipped with an oil-residue separator, where the residue is skimmed off and returned to the oil press for re-extraction. The clarified oil overflows into a crude oil tank, from which it’s pumped through a filter for purification. Finally, the filtered crude oil is transferred to the refining workshop for further processing and refinement.
