Example Embodiment
[0039] Embodiment 2 of the present invention is a production line for obtaining cedar essential oil with low energy consumption and high yield, and its structure is exactly the same as that of Embodiment 1.
[0040] A production method for obtaining cedar essential oil with low energy consumption and high yield, adopts the production line for obtaining cedar essential oil with low energy consumption and high yield, and the specific steps are as follows:
[0041] A. Flour milling: pulverize the raw material of fir into 120 mesh fir powder by cutting, slicing and crushing;
[0042] B. Mixing: Add edible alkali and industrial salt to the cedar powder for mixing. The weight ratio of the three is: 750 parts of cedar powder, 3.5 parts of edible alkali, and 2.2 parts of industrial salt;
[0043] C. One-time distillation. The mixed cedar powder is sent to the distillation tower, and superheated steam with a temperature of 260°C is passed into the distillation tower for one distillation, and th...

Abstract
The invention discloses a production method and a production line for obtaining Chinese fir essential oil at low energy and high yield. The production line comprises a boiler, a steam superheater, a block-cutting device, a slicing device, a crushing device, a stirring device, a distilling tower, a cooling tower and an oil and water separating device, and further comprises a solid and liquid separating device, a material collecting box with an overturning device 2 and a sprinkling device, and an overturning device 1 arranged inside the distilling tower, wherein a water outlet pipe of the cooling tower is communicated with the boiler; the sprinkling device is communicated with the oil and water separating device; a leachate outlet of the material collecting box is communicated with the oil and water separating device; a residue outlet of the material collecting box is connected with a feed inlet of the solid and liquid separating device; a liquid outlet of the solid and liquid separating device is communicated with an inlet of the oil and water separating device; a residue outlet of the solid and liquid separating device is connected with a fuel inlet of the boiler and a fuel inlet of the steam superheater through a conveyor belt distributed around the tower. After adoption of the production line, the Chinese fir essential oil is obtained by preparing powder, mixing, primarily distilling, secondarily distilling, cooling, sprinkling, overturning, performing solid and liquid separation, performing solid material drying and performing oil and water separation. The yield is high and the energy consumption is low.
Description
technical field [0001] The invention belongs to the technical field of extraction of Chinese fir essential oil, and relates to a production method and production line for obtaining Chinese fir essential oil with low energy consumption and high yield. Background technique [0002] Chinese fir contains a large amount of Chinese fir essential oil, the main components of which are cedrene, cedrene, etc., which can be used in the perfume industry. At present, the extraction and processing of fir essential oil mainly use solvent extraction, dry distillation, and steam distillation. The oil yield of Chinese fir essential oil extracted by solvent extraction is higher than that of steam distillation, but a large amount of solvent is required, the follow-up treatment is complicated, and there are problems of high energy consumption and solvent residue. The oil yield of Chinese fir essential oil extracted by dry distillation is relatively high, but it is a chemical process, and the ob...
