Today, the typically taken on technique in this industry is to make use of the unrefined extract of Perilla odorifera as the raw product, and make use of vacuum cleaner purification or solvent removal for splitting up. The solvent removal technique calls for the use of a large quantity of solvent for repeated condensation, and the getaway and leakage of the solvent It is not only a harmful element for production security, however likewise puts terrific pressure on the atmosphere. Although vacuum cleaner distillation can minimize environmental pollution, it likewise has the following troubles: 1. Low production effectiveness: the home heating procedure in vacuum distillation calls for at the very least 12 hours; 2. Low yield: The product components are conveniently destroyed by warm, so the product yield can just reach about 70%; 3. High energy consumption and high cost: A huge quantity of heat energy is consumed throughout vacuum purification, so the energy consumption is high., likewise raises manufacturing prices. Materials of the development:
The here and now innovation provides an approach for separating sclareol to overcome the problems of low production efficiency, reduced yield, high energy intake and high expense in the previous art.
In order to get rid of the troubles existing in the previous art, the technological remedy of the here and now innovation is: a technique for dividing sclareol, which includes the following action in sequence:
( 1) Pre-treatment: Warm the unrefined remove of Perilla oleracea and regulate the temperature at 80 ~ 250 ° C until it is totally
Thaw, move to a centrifugal removal maker with a warmth preservation system, do centrifugal extraction at a rate of 500-6000 rpm at 135 ~ 150 ° C to eliminate hefty stage matter;
( 2) First-stage purification: The crude essence of Perilla odorifera is sent to the molecular distiller, the pressure is controlled to 100 Pa – 150 , and the temperature is 190 ° C to 230 ° C. The crude remove is divided right into hefty stage and light phase after continual distillation., the hefty phase is directly discharged and discarded via a special pipe, and the light stage goes into the second distillation;
( 3) Additional distillation: The light stage gotten in step (2) is sent out to the molecular distiller once more with a stress of 30 Pascals to 70 Pascals and a temperature of 260 ° C to 300 ° C to obtain a fragrance with a purity of 90% to 98%. Perilla alcohol.
In those action (1 ): warm the crude essence of Perilla frutescens, control the temperature at 80 ~ 100 ° C, and entirely thaw it. Reduced energy consumption.
Compared to the prior art, the advantages of the present invention are as follows:
1. High production efficiency: the whole thermal splitting up procedure takes no more than 10 seconds;
2. High yield: As a result of the short home heating time and excellent conservation of item active ingredients, the complete return of the system can reach greater than 95%;.
3. Low power usage and affordable: The home heating time is short, so the energy consumption is considerably lowered.
