In order to improve the oil yield of the peanut oil press machine, the following methods can be adopted:

1.Selection of high-quality raw materials: Choosing high-quality peanuts as raw materials can improve the oil yield. High-quality peanuts should be moderately ripe, free of mildew, and free of foreign matter mixtures. When choosing raw materials, it is necessary to avoid using old or moldy peanuts, which can ensure the oil yield of the oil press machine.

2.Proper heat treatment: Before oil extraction, peanuts can be properly heated, which can destroy the cell structure in peanuts and facilitate the release of oil. However, the heating temperature and time should be well controlled to avoid excessive temperature and too long time to cause oxidation of oil and affect oil quality.

3.Reasonable oil press machine adjustment: The oil press adjustment also has a great impact on the oil yield. In the process of oil extraction, reasonable adjustment can be made according to the different characteristics of raw materials and oil content, including appropriate pressing strength, appropriate speed, etc.

4.Cleaning and maintenance: Regularly clean and maintain the oil press machine to keep the equipment clean and in good condition. In this way, it can avoid problems such as increased friction and poor sealing caused by unclean equipment, which will affect the oil yield.

5.Oil residue treatment: Reasonable treatment of oil residue after oil extraction can indirectly improve the oil yield. Through scientific and reasonable oil residue treatment, a part of the oil remaining in the oil residue can be recovered, and the overall oil yield can be improved.

Through the comprehensive application of the above methods, the oil yield of the peanut oil machine can be effectively improved, so as to improve the production efficiency and economic benefits.
