Vacuum refining method of health-care plant essential oil

Abstract

The invention relates to a vacuum refining method of health-care plant essential oil. According to the method, a distillation refining equipment is adopted, and the distillation refining equipment comprises a distillation tank, a top cover, a material placing device and an auxiliary device, the specific method for preparing the plant essential oil by adopting the distillation refining equipment comprises the following steps: cleaning raw materials, crushing the raw materials, heating, distilling, extracting, condensing and collecting, wherein a material placing device comprises an outer ring body, an inner ring body, a material bearing ring, a crushing rotating disc, a fixed ring seat, a driving gear ring, a driven gear, a stirring frame and a connecting frame. After plant raw materials are crushed through the material placing device, essential oil is extracted from the raw materials in a distillation mode under the cooperation effect of the auxiliary device, and meanwhile the materialplacing device can stir the raw materials in multiple directions, so that the situation that the raw materials at part of positions cannot make full contact with steam is avoided; the material placing device is detachably connected with the distillation tank, so that a worker can conveniently and periodically clean residual materials in the material placing device.

Description

technical field [0001] The invention relates to the technical field of plant essential oils, in particular to a vacuum extraction method for health-care plant essential oils. Background technique [0002] Plant essential oils are the unique aromatic substances extracted from plants. They are extracted from the flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbal plants through distillation and pressing. Due to the high volatility of plant essential oils and small molecules, they are easily absorbed by the human body and quickly penetrate into the internal organs of the human body. The fragrance of the plant itself also directly stimulates the secretion of pituitary gland, enzymes and hormones, thereby balancing internal functions and playing the role of beauty and health care. [0003] The production methods of plant essential oils include distillation, pressing, fat absorption and maceration, etc. Among them, distillation can be said to be the oldest and most...

AI Technical Summary

Problems solved by technology

[0004] However, there are some problems in the process of using vacuum distillation to extract plant essential oils: (1) The plant raw materials are mostly in a concentrated accumulation state during distillation, so the steam cannot fully contact with the raw materials at each position, resulting in low efficiency of essential oil extraction, Causes a certain degree of waste; (2) After the distillation, the plant material residues will accumulate inside the equipment, and the equipment needs to be disassembled regularly to clean the plant materials. The cleaning process takes a long time and the work intensity is high
