Preparation process for hemp oil

Abstract

The invention discloses a preparation process for hemp oil. The hemp seeds are subjected to three-stage screening the hemp seeds are separated from impurities; the selected hemp seeds are stir-fried;a squeezing machine is used for squeezing the hemp seeds at low temperature; the hempseeds are squeezed into hemp oil; the hemp oil is separated from the hemp oil residues; a precipitation box is usedfor carrying out three-stage precipitation on the hemp oil; the precipitated hemp oil is conveyed to a water refining device; the hemp oil subjected to water refining is conveyed to an alkali refining device; the hemp oil subjected to alkali refining is conveyed to a water washing device to be repeatedly washed for three times through a washing device; the washed hemp oil is conveyed to a heatingdevice, the heating device removes moisture contained in the hemp oil, the dehydrated hemp oil is conveyed to a filtering device, and an activated carbon layer arranged on the filtering device removes residual impurities in the hemp oil so that the problems that the hemp seeds are difficult to stir-fry uniformly, and the oil yield of the hemp seeds is relatively low are solved; and the problems that the impurities in the squeezed hemp oil are difficult to remove and thus the hemp oil is poor in taste can be solved.

Description

technical field [0001] The invention relates to a process, in particular to a process for making hemp oil. Background technique [0002] Hempseed, also known as hempseed, is the fruit of hemp. Northeast is also called thread hemp, also known as wild hemp and northern hemp. The plant skin of the plant can be woven into clothes in the old days, called hemp clothes, and can be twisted into ropes, called hemp rope. It is an ancient cultivated plant belonging to the genus Cannabis of the family Moraceae, an annual erect herb. Once listed as one of the "five grains", it is also an oil crop, the size of which is similar to sorghum grains (smaller than mung beans), and the shell is gray. After shelling, it is the hemp seed of traditional Chinese medicine, which has a mild laxative effect. In some places, hawkers pick up and sell fried hemp seeds for people to eat at leisure. [0003] It is used to extract hemp oil from hemp seeds, which is convenient for different people to eat. ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the existing hemp oil production process, it is difficult to stir-fry the hemp seeds evenly, resulting in a low oil yield of the hemp seeds; Poor, the purpose is to provide a pr
