Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment.

[0019] The production process of menthol and peppermint oil uses peppermint powder or peppermint oil as the raw material for production, and the steps are as follows:

[0020] ①. The raw materials are liquefied in the drying room, and the temperature in the drying room is controlled at 60-70°C to form mint raw material oil.

[0021] ②. Put the liquefied peppermint raw material oil into the dehydration tank, dehydrate it to less than 0.03%, control the temperature at 80-90°C, and control the vacuum degree at 720-750mmHg.

[0022] ③. Enter the blending kettle, and adjust to contain 87.5-88.5% of L-brain by adding ice oil (separation product in step ⑥) (the L-brain of mint powder is 96%, the L-brain of mint crude oil is 76%, and the ice oil contains L- Brain is 60%, and L-brain is an ingredient that exists in natural mint. Therefore, use low-level mint crude oil or ice oil to adjust to...

Abstract

The invention discloses a production technique of menthol and dementholized peppermint oil, which comprises the following steps: by using peppermint powder or peppermint oil as the production raw material, liquefying the raw material in a drying chamber to form peppermint raw oil; driving the liquefied peppermint raw oil into a dehydration tank to carry out dehydration; sending into a regulating kettle, and regulating the peppermint raw oil until the levo-menthol content is 87.5-88.5%; pressing into a filter press to filter out impurities: sending into a crystallization house to carry out crystallization; separating out semi-finished menthol and ice oil; baking the semi-finished menthol, cooling, and packaging to obtain the finished menthol; freezing the ice oil to precipitate raw dementholized oil; dehydrating the raw dementholized oil, distilling in a distilling still to separate out dementholized peppermint oil and residues, and filtering out impurities from the dementholized peppermint oil by using the filter press, thereby obtaining the dementholized peppermint oil. The production technique of menthol and dementholized peppermint oil is reasonably designed, and the produced menthol and dementholized peppermint oil have high quality.

Description

[0001] technical field [0002] The invention discloses a production process of menthol and mint oil. Background technique [0003] In the prior art, the production of menthol and peppermint oil generally has more impurities and lower quality. Contents of the invention [0004] In order to solve the technical problems existing in the prior art, the object of the present invention is to provide a kind of menthol and mint oil production process, the menthol and mint oil produced are of higher quality. [0005] The technical scheme that the present invention adopts is as follows: [0006] A kind of menthol and peppermint oil production process is to use peppermint powder or peppermint oil as production raw material, it is characterized in that, the steps are as follows: [0007] ①. The raw materials are liquefied in the drying room, and the temperature in the drying room is controlled at 60-70°C to form mint raw material oil; [0008] ②. Pour the liquefied peppermint raw m...
