Put the castor bean raw material into the extraction kettle, compress the extractant into a liquid at the extraction temperature of 50°C-80°C and the extraction pressure of 0.5Mpa-1.8Mpa, and flow it at a flow rate of 100L/h-150L/h Through the extraction kettle, extract continuously for 120min-180min. After extracting the castor oil, it flows into the analysis kettle. The analysis temperature is 60°C-80°C, and the analysis pressure is 0.1Mpa-0.5Mpa. It becomes a gas, and then through instant compression, it becomes a liquid and then flows through the extraction kettle to extract the material again, and so on for many times;
