High efficiency distiller for production of cunninghamia lanceolata essential oil

Abstract

The invention discloses a high efficiency distiller for production of cunninghamia lanceolata essential oil. The distiller includes a tank. A ventilation partition plate is disposed close to the bottom in the tank and separates the inner cavity of the tank into a big upper cavity and a small lower cavity, the tank top surface is provided with a feed inlet, the upper part of the big cavity is provided with a mixed gas outlet pipe, a steam inlet pipe is inserted into the small cavity, and a tank side is provided with a slag hole and a slag door; a plurality of vent pipes are detachably inserted in a vertical direction in the tank; the peripheral surfaces of the vent pipes are densely covered air vents; the tops of the vent pipes are sealed, the positions of the tops are lower than the position of the mixed gas outlet pipe, and the top surfaces of the vent pipes are equipped with lifting lugs; the bottom surfaces of the vent pipes are equipped with pipe bottom openings; the bottom surface in the tank is equipped with pedestals that are equal to the number of the vent pipes and can be used for insertion of corresponding vent pipes; and the ventilation partition plate is equipped with partition plate openings with a number equal to that of the vent pipes. Under the premise of ensuring the feeding and slagging convenience and space utilization, the distiller provided by the invention has improved distillation efficiency and greatly shortened distillation time.

Description

technical field [0001] The invention belongs to the technical field of extracting Chinese fir essential oil, and relates to a high-efficiency distiller for producing Chinese fir essential oil. 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 obtained essential oil contains a large amount of tar, pheno...

Problems solved by technology

[0005] Of course, distillers using this technology can be used, but in order to maximize the use of space in the distiller, the large cavity is basically filled with fir powder, and the thick and dense fir powder is more dense after being injected with water vapor. Poor air permeability makes it difficult for the material to evaporate thoroughly and evenly, so the required distillation time usually takes up to 9-11 hours. The time required for distillation is too long, the distillation efficiency is low, and the use effect is not ideal.
