Method Of Obtaining Castor Oil
Jul 25, 2018

Castor bean oil contains high oil content, because of the use of oil is different, therefore the oil extraction method is different, the medicinal castor oil is cold-pressed by the hydraulic press, the temperature is not more than 50, otherwise some impurities will dissolve into the oil and cannot be used as medicine. The oil obtained by cold pressing is called no. 1 castor oil. After the cake is crushed, the no.3 castor oil (no. 2) is extracted by pressing or leaching again for industrial use. The castor oil obtained by screw press or prepress - leaching can only be used as industrial oil.
