Description
Technical Field
The invention relates to the technical field of mouse repellents, in particular to a low-temperature vacuum extraction method of thuja oil.
Background
The root and the trunk of the died arborvitae in the rock seams of the taihang mountains in the North China absorb the natural and earth essence gas due to the growth in an extremely severe environment and are blown and scraped by the powerful wind of the arborvitae, so that the died arborvitae forms a peculiar elegant, bent and flexible shape, and the wood has high density and large oiliness and has mellow cedar fragrance. The root and trunk of arborvitae in Yanshan mountain have been used in root carving, ornament base, pillow and Buddha bead because they grow in relatively comfortable environment, and have a gentle and smooth shape, most of them have the characteristics of high density, large oiliness, fragrant smell, mellow and strong taste, and have a long-term storage and a better taste.
Thuja is a natural plant which cannot be artificially cultivated and planted, is small in quantity and non-renewable, particularly, the thuja growing on the cliff is relatively small in quantity, is light coffee-colored and is commonly called as an aging material, and is stable in smell and comfortable in fragrance after being blown by wind and sun for hundreds of thousands of years.
The essential oil extracted from thuja has the following medicinal value: anhui and Dinghui can improve insomnia and dreaminess, and its fragrance can increase blood oxygen content to make people be delightful. Also has effects of removing toxic substance, caring skin, resisting inflammation, and removing toxic substance, and can purify air, kill bacteria and virus, and has anti-inflammatory and repercussive effects. The oil extracted from the aged material is commonly called aged material and has high value, but the current oil extraction methods mainly comprise several methods: the first method is that thuja is smashed into powder and then steam distillation is carried out, which destroys the original fragrance of the aging material; the second method is critical extraction of carbon dioxide, the thuja is smashed into powder, the powder is absorbed in liquid carbon dioxide, and the carbon dioxide is sublimated after absorption. The fourth method, a subcritical low-temperature extraction method, is shown in fig. 2, which is generally aimed at extracting oil in large quantities, the whole equipment is expensive, and small-scale companies cannot implement the method at all, and the oil extraction method can mix a small part of extraction liquid, so that the aroma of thuja is changed. In addition, the distillation extraction and the carbon dioxide critical extraction of two methods for extracting the thuja oil almost have little utilization value of the obtained massive thuja slag, which is a great waste and has low utilization rate of the thuja.

Preferably, in step S1, the slice has a thickness of 5-7mm, which results in fast oil extraction and low vacuum pump requirements, and can be operated with a vacuum pump with a low vacuum degree, so that the equipment cost is low.
Preferably, in the step S1, the cut direction of the cut piece is perpendicular to the grain of the thuja, so that the oil in the thuja is not easily hidden in the grain of the thuja, and the oil easily seeps out of the thuja after vacuum pumping.
Preferably, in the step S2, when the thuja slices are placed in the oil collecting cup, any two slices are not adhered to each other, so that the oil is not hidden between the two slices, and the oil can smoothly flow down along the section of the thuja.
Preferably, in step S1, the lower portion of the slice is pointed to facilitate the collection of oil.
Preferably, in step S1, a nail is nailed at the bottom of the sliced sheet as the guide flow.
The invention has the beneficial effects that:
the low-temperature vacuum extraction method of the thuja oil adopts a low-temperature vacuum oil extraction technology to extract oil from thuja, the oil extraction rate reaches 4%, the extracted oil is pure and free of impurities, the original fragrance of the thuja oil is retained, and the extracted thuja oil is high in quality. The thuja sawdust can be used as external medicine by soaking in wine, has the effects of repelling mosquitoes, traumatic injuries, relieving pain and the like, can be used for foot bath by boiling water, can also be used as fumigation material, and can be used as backflow incense, line incense and incense pieces after being collected by a cyclone dust collecting device. The thuja slices after vacuum pumping and oil extraction have a plurality of purposes, can be used as artware, such as relief combs, health-preserving acupoint scrapers and the like, and can also be smashed into powder to be used together with thuja sawdust, so that the utilization rate of thuja is greatly improved. The whole set of equipment for vacuum oil extraction is low in cost, can be borne by small companies, is simple to operate, and can be operated by common workers.
