Embodiment Construction

[0009] Preparation method of fir essential oil:

[0010] 1. Screen the collected Chinese fir chips, remove slabs, wood blocks, fine powder and other sundries (which can be used as boiler fuel), and dry to keep the moisture content at 20-25%;

[0011] 2. Add the screened fir chips from the upper mouth of the retort with a conveyor, leave a space of 30 cm on the upper part of the retort, and close the upper cover of the retort.

[0012] 3. First-level distillation, close the valve of the distillation pipe on the upper part of the distillation tank, feed steam, adjust the steam pressure of the boiler to 5-7 Mpa (MPa), keep the water vapor flow at 94ml / min, and wait for the temperature in the distillation tank to rise When it reaches 120°C, keep it for 20-30 minutes; under the action of pressure, water vapor enters the cells of lignin and cellulose, on the one hand, it dilutes the essential oil solidified in the cell wall, and on the other hand, it forces the cell cavity to expand...

Abstract

The invention discloses a production method used for producing cunninghamia lanceolata biological essential oil from cunninghamia lanceolata saw dust. According to the production method, cunninghamia lanceolata saw dust is delivered into a vertical distillation tank, boiler steam is delivered into the vertical distillation tank from the bottom, after three-stage distillation, obtained essential oil is collected from a distillation outlet pipe on the upper part of the vertical distillation tank together with water vapor, and is delivered into a condenser, and cunninghamia lanceolata biological essential oil is obtained oil-water separation after cooling. According to the production method, waste saw dust generated in wood processing is used; the cunninghamia lanceolata biological essential oil is extracted via fine processing; enterprise economic benefit is improved; discharge of harmful gas is reduced; and the ecological environment is protected.

Description

technical field [0001] The invention relates to a technology for extracting biological essential oil, in particular to a production method for steaming Chinese fir biological oil. Background technique [0002] Plant extracts use plants as raw materials. According to the needs of the final product of extraction, through physical or chemical separation and extraction processes, one or more active ingredients in plants are directional obtained and concentrated without changing their effective ingredients. Products formed by the composition structure. [0003] Biological extracts have their unique physiological functions and play an important role in food, medicine, health care, and beauty. Cedarwood essential oil is an oily liquid with aroma and volatility. Its main components are cedaryl alcohol and cedarene, which have physiological activities and are widely used. One is a natural fungicide and preservative for food, fruit and vegetable storage; the other is used as a raw ma...
