Embodiment 1

[0015] A method for separating sclareol includes the following steps in sequence:

[0016] (1) Pre-treatment: add 200kg of sage perilla extract with a content of 45.2% into a distillation kettle and heat to 85-90 degrees to melt to a liquid state, use a centrifugal extractor with a thermal insulation system at a temperature of 150°C, 2000 rpm Centrifugal extraction at a speed of 1 minute to remove heavy phase substances (mainly impurities such as external impurities, high-polarity, high-density and high-melting point extracts, some of which are very harmful to the normal operation of the molecular distiller);

[0017] (2) Primary distillation: After the pretreatment is completed, the initial extract is added to the molecular distiller, and the pressure is maintained at 130 Pa and the temperature is 200 degrees. After distillation, the crude extract is divided into heavy phase (waste impurities) and light phase (higher). The content of the crude extract of Fragaria vulgaris), the h...

Embodiment 2

[0020] A method for separating sclareol includes the following steps in sequence:

[0021] (1) Pre-treatment: Add 260kg of sage perilla extract with a content of 48.6% to a distillation kettle and heat to 90-95 degrees to melt to a liquid state. Use a centrifugal extractor with a thermal insulation system at a temperature of 135°C and 5000 rpm. Centrifugal extraction at a rotation speed of 1 minute to remove heavy phases;

[0022] (2) Primary distillation: After the pretreatment is completed, the initial extract is added to the molecular distiller, and the pressure is maintained at 140 Pa and the temperature is 205 degrees. The crude extract is divided into heavy phase and light phase after distillation, and the heavy phase is directly discharged through a special pipeline Discard, the light phase enters the secondary distillation;

[0023] (3) Two-stage distillation: the light phase obtained in step (2) is added to a molecular distiller in normal operation. The molecular distille...

Embodiment 3

[0025] A method for separating sclareol includes the following steps in sequence:

[0026] (1) Pre-treatment: add 150kg of scented perilla extract with a content of 50.2% into a distillation kettle and heat to 150-155 degrees to melt to a liquid state, use a centrifugal extractor with a thermal insulation system at a temperature of 150°C, 1000 rpm Centrifugal extraction at a rotation speed of 1 minute to remove heavy phases;

[0027] (2) One-stage distillation: After the pretreatment is completed, the initial extract is added to the molecular distiller, and the pressure is maintained at 110 Pa and the temperature is 195 degrees. The crude extract is divided into heavy phase and light phase after distillation, and the heavy phase is directly discharged through a special pipeline Discard, the light phase enters the secondary distillation;

[0028] (3) Two-stage distillation: the light phase obtained in step (2) is added to a molecular distiller in normal operation. The molecular dis...

Abstract

The invention relates to the technical field of natural perfume separation, in particular to a separation method of sclareol. The invention overcomes the problems in the prior art that the production efficiency is low, the yield is low, the energy consumption is great and the cost is high. Aiming at overcoming the problems in the prior art, the technical proposal of the invention is as follows: the separation method of the sclareol comprises the following steps sequentially: (1) preliminary treatment: the crude extract of sage clary is heated to be fully melted, and centrifugal extraction is carried out to remove heavy phase substances; (2) primary stage of distillation: the crude extract of the sage clary is sent to a molecular still, after continuous distillation, the extract is divided into heavy phase and light phase, wherein, the light phase is carried out with secondary distillation; and (3) secondary distillation: the light phase obtained in the step (2) is sent to the molecular still again to obtain the sclareol with the concentration of 90 to 98 percent. Compared with the prior art, the method has the advantages of high production efficiency, high yield reaching more than 95 percent, low energy consumption and low cost.

Description

Technical field: [0001] The present invention relates to the technical field of separation of natural spices, in particular to a method for separating sclareol. Background technique: [0002] Sclareol is extracted from the inflorescence of Salvia Sclare L. as a raw material, and has many physiological activities such as antibacterial and acne elimination. At present, the method generally adopted in this industry is: using the crude extract of sage perilla as the raw material, using vacuum distillation or solvent extraction method to separate, wherein the solvent extraction method requires the use of a large number of solvents for repeated crystallization, and the escape and leakage of the solvent It is not only a dangerous factor for safe production, but also a great pressure on the environment. Although vacuum distillation can reduce environmental pollution, it also has the following problems: 1. Low production efficiency: the heating process in vacuum distillation requires at l...
