Adjust the operating parameters
1. Inlet moisture and temperature: Maintaining appropriate inlet moisture and temperature is the key to improving the oil yield. Under normal circumstances, the inlet moisture should be controlled within an appropriate range. Too high or too low will affect the oil yield. At the same time, the inlet temperature should also be moderate, generally between 110 and 130°C.
2. Cake thickness: The adjustment of cake thickness is also an important factor affecting the oil yield. Too thick cakes will lead to insufficient chamber pressure and low oil yield; while too thin cakes may increase the machine load and even cause accidents. Therefore, the cake thickness should be adjusted according to the actual situation to achieve the best oil yield effect.
Optimize raw material processing
1. Raw material selection and pretreatment: Selecting raw materials with high oil content and good quality can improve the oil yield. At the same time, proper pretreatment of raw materials such as soaking and frying can also help improve the oil yield.
2. Cleanliness of raw materials: Ensuring the cleanliness of raw materials is the basis for improving oil yield. Impurities and sand in the oil will affect the normal operation of the press, reduce the oil yield and damage the quality of the oil. Therefore, the raw materials should be screened and cleaned before oil pressing.
Maintenance and maintenance of equipment
1. Keep the equipment clean: Regularly clean the residues and oil residues inside the oil press to keep the equipment clean, which will help improve the oil yield.
2. Check and replace worn parts: Regularly check the wear of the screw shaft, screw and other parts of the oil press, and replace the seriously worn parts in time to ensure the normal operation of the equipment and improve the oil yield.
In addition, the adjustment of the thickness of the oil press cake is mainly achieved by adjusting the adjusting bolts of the oil press.
In summary, improving the oil yield of the oil press requires adjustment and optimization from multiple aspects.
