How to improve the oil yield of oil press machine?

Jun. 21, 2024
Selection and treatment of oilseeds:
Select oilseeds with high maturity and full seeds, because such oilseeds have high oil content and are more favorable for oil production.
Ensure that the oilseeds are clean and have low dregs content to minimize impurities in the oil extraction process and increase the oil yield.
Properly control the dryness and humidity of the oilseed, too low or too high moisture will affect the oil yield. Generally speaking, the moisture content of oilseeds should be adjusted according to the specific oilseed type to achieve the best oil yield.
Pre-treatment of oilseeds, such as cleaning impurities, shelling, crushing and steaming, etc. These steps can significantly improve the oil yield of the oil press.
Adjustment of pressing process:

Adopt hot pressing process, because hot pressing has higher oil yield than cold pressing. Frying the oilseeds before hot pressing requires strict control of fire and time to avoid over or under frying.
Adjust the pressing process according to different oilseed crops to adapt to the characteristics of various oilseeds.
Maintenance of equipment:

Regularly check and lubricate the various parts of the oil press to ensure that the equipment runs well and to reduce the impact of wear and tear of parts on the oil yield.
Replace the worn parts in time, such as press screw, press bar, cake head, etc., to keep the equipment in the best condition.
At the end of the production season, carry out comprehensive maintenance of the equipment, including cleaning residue, wiping clean the machine surface dust and grease, and disassembling and reassembling the key parts to be oiled and stored in a dry place.
Control of processing environment:

Keep the room temperature of the oil press room at 15℃~20℃, because too low temperature will affect the oil yield and oil quality.
After the machine is air running normally, then feed a small amount of oil evenly and slowly in order to grind the chamber hot, and observe the oil press for any strange noise and other problems.
Through the comprehensive application of the above methods, the oil yield of the oil press can be effectively improved, and at the same time ensure the quality and yield of the oil.
