Embodiment Construction

[0013] A method for extracting essential oils from pine nuts, which is characterized in that the following steps are carried out in sequence: purchasing pines, controlling the dryness and fermentation of pines, improving extraction at normal temperature and high pressure, determining the condensation of pine crude oil, heating and Crude oil is refined.

[0014] The time for the acquisition of nard pine is based on the growth characteristics of nard pine, and the biological content is different in different seasons. According to my own research, the quality and oil yield of nard pine grown at an altitude of 3500-4000 meters and harvested from mid-April to mid-July meet the production standards of the enterprise.

[0015] Said control of drying degree and fermentation of sweet pine: in the drying process of sweet pine, the first step must control the drying method, carry out normal temperature drying and drying treatment, and the drying treatment temperature must be controlled b...

Abstract

The invention relates to a method for extracting essential oil by taking nardostachys chinensis as a raw material. The method is characterized by comprising the following steps of: purchasing the nardostachys chinensis; controlling the airing dryness of the nardostachys chinensis and fermenting; extracting the nardostachys chinensis at normal temperature under high pressure; condensing nardostachys chinensis crude oil; and heating and refining the crude oil. Due to the adoption of the technical scheme, the quality and oil yield of the nardostachys chinensis crude oil are ensured, and energy consumption is reduced; and an interlayer is arranged in a distillation tank additionally, so that the permeability of steam can be improved, and the oil yield is improved by 1 percent integrally.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for extracting flavors and spices. Background technique [0002] Pickling and storage of sweet pine: the existing technology adopts perennial purchase, regardless of season; drying of sweet pine: the prior art adopts drying on flat ground without any treatment; extraction of sweet pine at room temperature and high pressure: the prior art adopts heating , pressurization, and oil output, without precise control of heating pressure and time; crude oil condensation: the existing technology adopts oil output and condensation, without any technical treatment; crude oil refining: no domestic related technical reports have been seen. [0003] The existing technology can process Nardinus crude oil, but the oil yield is low; the crude oil is not refined, and there are impurities that are not completely separated, poor in color and high in acidity. Contents of the invention [000...
