Device for extracting castor oil from castor cold pressed oil

Abstract

The invention relates to castor oil, particularly to a device for extracting castor oil from castor cold pressed oil. The technical problem to be solved by the invention is to provide a device for extracting castor oil from castor cold pressed oil. In order to solve the technical problem, the invention provides a device for extracting castor oil from castor cold pressed oil, wherein the device comprises a support frame, a control display screen, a low-pressure dehydration device, a liquid separation device, a decoloration filter pressing device and a preheating saponification device, the low-pressure dehydration device is arranged in the middle of the right end in the support frame, the liquid separation device is arranged at the middle upper portion of the right end in the support frame,the bottom end of the liquid separation device is connected with the low-pressure dehydration device, the decoloration filter pressing device is arranged in middle of the top end of support frame, andthe right end of decoloration filter pressing device is connected with the low-pressure dehydration device. According to the invention, the device has high saponification rate, precisely separates higher sodium aliphatate and glycerol, cannot cause crystal doping, and achieves high standard decolorization effect by matching white pot clay and active carbon.

Description

technical field [0001] The invention relates to castor oil, in particular to a castor oil refining device for cold-pressed castor oil. Background technique [0002] Castor oil refining (different from castor oil production), research on post-processing of castor oil, how to remove impurities from castor oil, how to improve the purity of castor oil, how to make castor oil more in line with market demand, etc. Castor oil refining involves technology The field is very extensive, among which chemical categories are the main category, and based on chemical experiments, higher standard refining technology of castor oil is studied. With the rapid development of science and technology, the equipment for refining castor oil from castor cold pressed oil has also obtained technology Improvement, but in the prior art new castor oil cold-pressed oil refining castor oil device is used because the heating device is not reasonable enough, the catalyst and the reactant cannot carry out the c...

Problems solved by technology

[0004] The present invention is in order to overcome prior art novel castor oil cold-pressed oil refinement castor oil device, because heating device is not reasonable enough when using, and catalyst and reactant can't carry out catalytic reaction at sufficient temperature, and the device that separates mixed solution is not accurate enough, in decolorization stage , the underlying kaolin does not participate in the reaction, resulting in a large waste of glycerin in the leaching stage, low saponification rate, too many impurities in glycerin separation, and the shortcoming that kaolin cannot be fully utilized in the decolorization process. The technology to be solved by the present invention The problem is to provide a device for refining castor oil from castor oil by cold pressing
