At present, the approach generally used in this industry is: make use of the crude extract of Clary Perilla as resources, and also different it by vacuum distillation or solvent extraction. The solvent extraction approach requires to use a huge amount of solvent for duplicated condensation, as well as the retreat and leakage of the solvent It is not only a harmful variable for secure production, yet additionally triggers excellent pressure on the atmosphere. Although vacuum cleaner purification can reduce environmental pollution, it additionally has the adhering to problems: 1. Low production effectiveness: the home heating procedure in vacuum distillation needs at the very least 12 hrs; 2. Low return: the product components are easily destroyed by warm, so the product yield can only get to around 70%; 3. High energy consumption and high price: a big amount of heat energy is eaten during vacuum distillation, so the power consumption is huge, also increases the production cost. Invention web content:
Today creation will give a sort of splitting up approach of sclareol, to get rid of the issues of low production performance, reduced return, large energy intake and also high cost in the previous art.
For getting rid of the trouble that previous art exists, technical system of the here and now innovation is: a type of splitting up technique of sclareol, consists of the complying with actions successively:
( 1) Pre-treatment: warming the unrefined remove of Clary Perilla, the temperature level is managed at 80 ~ 250 ° C up until completely
Thaw, be transferred in the centrifugal extractor of band insulation system, at 135 ～ 150 ℃, perform centrifugal removal with the turning rate of 500-6000 rev/min, eliminate heavy stage;
( 2) One-stage purification: the unrefined essence of Clarissa is sent to a molecular still, the stress is regulated at 100 Pa-150 , the temperature level is 190 ° C to 230 ° C, and the unrefined remove is separated right into hefty phase and also light stage after continuous distillation, the heavy phase is directly discharged with a special pipe as well as thrown out, and also the light stage enters the additional purification;
( 3) Additional distillation: the light stage obtained in step (2) is sent to the molecular still once again, with a pressure of 30 Pa to 70 , as well as a temperature level of 260 ° C to 300 ° C, to obtain a fragrance with a purity of 90% -98%. perillyl alcohol.
In the above-mentioned steps (1 ): the unrefined essence of Clary Perilla is warmed, as well as the temperature is regulated at 80 ~ 100 ° C, totally melted. Power usage is reduced.
Compared to prior art, the present development has the following advantages:
1. High production effectiveness: the whole thermal splitting up process does not exceed 10 seconds;
2. High return: because of the brief home heating time, the item components are well protected, so that the total return of the system can reach greater than 95%;.
3. Low power consumption and low cost: the home heating time is short, so the power intake is considerably lowered.
