Process Characteristics And Pressing Method Of Castor Oil
The process characteristics and pressing methods of castor oil can be summarized as follows:
Process characteristics：
1. Multi-step production: The production process of castor oil includes planting, harvesting, extraction and refining steps, each step needs strict control to ensure the quality and safety of the product.
2. High raw material requirements: Castor needs to grow in a warm and humid environment, and the soil needs to be loose and well-drained. It is necessary to pay attention to fertilization, watering and insect control in the planting process to ensure the growth and yield of castor beans.
3. Various extraction methods: the extraction of castor oil can be carried out by cold pressing or solvent extraction, wherein the cold pressing extraction is to press the castor seed to make the oil flow out; Solvent extraction is to mix castor seeds with organic solvents, dissolve the oil in the solvent, and then get pure castor oil by evaporating the solvent.
4. The refining process is complex: the refining process mainly includes steps such as removing impurities, removing acid and deodorizing. Removing impurities is to improve purity; Deacidification is to reduce the acidity of free fatty acids and improve the quality of oil. Deodorization is to remove the odor and make the castor oil more fragrant.
Press method
1.Manual press：
1) Dry castor seeds and remove impurities.
2) Use a manual press to crush the castor seeds into a fine powder.
3) Put the fine powder into a press bag and squeeze out the oil.
4) Squeeze and sift repeatedly until you get pure castor oil.
5) This method is simple and easy to master, but the efficiency is low.
2. Mechanical press:
1) Wash castor seeds and remove impurities.
2) Use a dryer to dry the castor seeds.
3) Use a castor seed press to extract oil.
4)After precipitation, deimpurity, deodorization, filtration and other post-treatment processes, to obtain pure castor oil.
5) Compared with manual operation, mechanical pressing is more efficient and more suitable for large-scale production.
3. Specific use press:
1)Medicinal castor oil is cold pressed by hydraulic press, and the temperature does not exceed 50 ° C to ensure that some impurities will not dissolve into the oil. This cold-pressed oil is called castor oil No. 1.
2) Industrial castor oil may be directly pressed by screw press, and screw press can choose MCRYAONE's machine, the company's machine quality is very good, the company's after-sales is also very in place, if you have the need to buy screw press, MCRAYONE's machine is the only choice for everyone.
In summary, the process characteristics of castor oil are reflected in its multi-step production process and strict extraction and refining requirements. According to the scale of production and the use of the product, there are manual and mechanical, as well as specific medical and industrial pressing methods.
