Rectification device and production method thereof

Abstract

The invention discloses a rectification device and a production method thereof. According to the invention, a plant fragrance oil liquid flowing out from the bottom part of a rectification tower is heated by a reboiler, and a heated liquid is pumped to the top part of the rectification tower by a second reflux pump, so large top-to-bottom circulation is realized, and the time of heating is shortened; and steam is provided for a sleeve pipe of a second-stage discharging pipe through a first-stage discharging pipe, so the effect of melting plugging is good. The tower top of the rectification tower is provided with a feeding pipe and the first-stage discharging pipe; a condenser is connected with and arranged on the first-stage discharging pipe in a sealed manner; the condenser and a temporary storage unit are in communication through the second-stage discharging pipe; the temporary storage unit communicates with an essential oil collector through a third-stage discharging pipe; the bottom part of the temporary storage unit is connected with the top part of the rectification tower through a reflux pipe; the reboiler communicates with the bottom part of the rectification tower througha reboiler feeding pipe; the bottom part of the reboiler is connected with the top part of the rectification tower through a reboiler discharging pipe which is provided with the second reflux pump; and the exterior of the second-stage discharging pipe is provided with the sleeve pipe used for steam flowing. The invention relates to the technical field of purification of plant fragrance oil.

Description

technical field [0001] The invention relates to the technical field of plant spice oil purification, in particular to a rectification device and a production method thereof. Background technique [0002] Vegetable fragrance oils, such as anethole, are widely used in daily life. In the prior art, the purification method of vegetable spice oil is generally to heat the vegetable spice oil in a rectification tower to make it volatilize, then condense the essential oil through a condenser, and then collect the rectified product by an essential oil collector. [0003] At present, the reboiler is generally located at the bottom of the rectification tower, and the pipeline is drawn from the bottom to the reboiler. The vegetable spice oil flows along the pipeline to the reboiler, and after being heated by the reboiler, it passes through another pipe. The road is transported back to the bottom of the rectification tower, or the inlet of the rectification tower at a position slightly ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the heating liquid of vegetable spice oil only flows in a small range near the bottom of the rectification tower, the liquid is ready to be heated to the same overall temperature for a long time, and the secondary discharge of the condenser communicated with the temporary storage The pipe is often blocked, the steam inlet pipe that needs to transport steam from the bottom of the rectification tower to the casing of the secondary discharge pipe is too long, and the temperature drop is too fast. A rectification device and its production method are provided. The reboiler heats the vegetable spice oil liquid flowing out from the bottom of the rectification tower, cooperates with the high-temperature magnetic pump as the second reflux pump, and then pumps the heated vegetable spice oil liquid to the top of the rectification tower, so that the plants in the rectification tower The spice oil liquid realizes a large-scale circulation heating from top to bottom, shortens the heating time of the liquid in the rectification tower, and also realizes the consistency of the overall temperature of the liquid, so the temperature of the upper liquid in the rectification tower can be increased, The first-stage discharge pipe at the top of the rectification tower can directly provide sufficient high-temperature steam to the casing of the second-stage discharge pipe, which has a good effect of melting blockage and saves energy
