In the production of rice bran oil, considering that rice bran has low oil content, small volume and high powder degree, the extraction method is often used to produce rice bran oil. In order to increase the contact area between oil and solvent during the extraction process, rice bran is often expanded in industrial production, which is also a kind of oil pretreatment process.
The extrusion of oil material is the process of using oil extrusion equipment to make oilseeds into puffed granular materials. After extrusion, the oilseeds can be directly extracted and made into oil. Using oil extrusion equipment to process oil is conducive to shortening the extraction time, accelerating the output, reducing the solvent ratio, evaporating easily, reducing energy consumption, reducing the residual oil rate in the meal, making the extraction more sufficient, and extrusion at high temperature for a short time to accelerate the quality of the product.
After rice bran is expanded, extraction is beneficial to improve the quality of rice bran and obtain good quality oil. In actual production, rice bran oil mills need to pay attention to the following: when expanding rice bran, the material in the feeder should be exhausted, the feeder should be stopped, the main machine should be stopped, the steam valve should be closed, the template should be opened, the main machine should be restarted, the material in the barrel should be emptied, and the template should be installed.
If a sudden shutdown or equipment failure occurs during the rice bran expansion process, it is recommended that the oil mill should handle it calmly. You can first turn off the power of the main machine and feeder, close the steam valve, open the template, manually pull the transmission belt to empty the material in the barrel, and install the template. Turn off the feed motor, shut down the oil expansion equipment, open the template and manually clean the material in the machine body; check the steam hose to avoid blockage.
During the expansion process, special attention should also be paid to the transmission parts of the oil expansion equipment during operation, and take timely measures to solve the problem. Check the feed port to avoid ironware entering and blocking. Check the operation of the steam pipeline during production to ensure its normal operation. Clean the equipment hygiene and keep the oil expansion equipment clean.
The above are all matters that need to be paid attention to during the rice bran extrusion process. There are also many matters that the oil mill needs to pay attention to during the rice bran oil extraction process. For this, the rice bran oil mill can choose to cooperate with Henan Huatai Cereals and Oils Machinery Co., Ltd. Manufacturer. The manufacturer’s staff will provide you with on-site training and guidance to help the oil mill’s production.
