Linalool distillation extraction device and technology

Abstract

The invention belongs to the field of chemical engineering and in particular relates to a linalool distillation device and technology. The linalool distillation extraction device comprises a center shaft, a shell and a motor, wherein a steam inlet pipe is arranged at one side of the bottom of the shell, a discharging hole is formed in the other side of the bottom of the shell, a charging hole is formed in the top of the shell, a steam outlet pipe is arranged at the top of the shell, one glass partition is arranged at each of the two sides of the shell, the two glass partitions are in diagonal distribution, a microwave transmitter is welded outside the glass partitions, the center shaft is arranged at the middle part of the inner cavity of the distillation device, the center shaft is provided with multiple metal impellers, a support and a motor are arranged at the bottom of the shell, and the motor is connected with the center shaft in a transmission manner. The linalool distillation technology comprises the following steps: 1) picking raw materials; 2) cutting up cinnamomum camphor leaves; 3) squeezing the cinnamomum camphor leaves; 4) treating the cinnamomum camphor leaves; 5) distilling; 6) condensing; 7) carrying out oil-water separation; and 8) carrying out crystallization and removing impurities.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a linalool distillation extraction device and process. Background technique [0002] Linalool (Linalool) is also known as linalool, linalool, coriander alcohol, coriander alcohol, galwood alcohol, linalool, etc. The scientific name is 3,7-dimethyl-1.6-octadiene-3-ol or 3,7-dimethyl-octadiene-[1,6]-ol-[3]. [0003] Linalool is one of the most frequently used spices in the formulations of perfume flavors, home chemical product flavors and soap flavors. It is also used to prepare food flavors. Now more than 15,000 tons of linalool are used in the preparation of various flavors in the world ; At the same time, linalool is also an important chemical raw material for the synthesis of various linalyl fragrances. [0004] At present, linalool can be obtained through distillation extraction from natural plants or artificial chemical synthesis. Artificial chemical synthesis ...

AI Technical Summary

Problems solved by technology

[0006] The traditional linalool distillation method is a single steam distillation, and the steaming speed of linalool is slow; in traditional distillation equipment, the raw materials are piled up statically, the heat exchange is insufficient, the distillation efficiency is low, and it needs to continue to feed steam for a long time

Therefore, traditional steam distillation methods and equipment have problems such as long distillation time, high energy consumption, and low efficiency.

[0007] In the traditional linalool process, the linalool obtained by distillation usually contains a small amount of impurities (its main component is camphor), which needs to be rectified again to remove impurities, which is cumbersome and consumes a lot of energy.
