Problems solved by technology

[0002] With the development of science and technology, people's demand for food is no longer primary demand, such as: flowers, citrus, tea, coffee and fruit, etc., after crushing, pulp, and solvent extraction Extract the beneficial ingredients in them to make high-grade food, health care products, and medicines for our use. During extraction, ethanol and ethyl acetate are often used for extraction. After extraction, the organic solvent in the mixture needs to be separated, and The existing separation method is to separate the organic solvent as a whole. After the separation, the solvent is in a mixed state, and it is difficult to collect and reuse after separate separation. Therefore, we propose a solvent separation method for plant extraction mixtures to solve the above problems.

Embodiment 1

[0021] Example 1: Such as Figure 1 As shown, the present invention provides a solvent separation method for plant extraction mixtures, comprising the following steps:

[0022] S1, the overall evaporative concentration: the extraction mixture is added to the concentration tank, heated evaporation concentration, mixed steam flows out from the top of the concentration tank, and the bottom product is extractant;

[0023] S2, overall condensation: the mixed steam through the heat exchanger after the overall condensation into the distillation tank;

[0024] S3, distillation: add hot water to the sandwich of the distillation tank, evaporate and separate the organic solvent from the water, the solvent vapor flows out from the top of the distillation tank, and the solvent vapor is condensed through the heat exchanger and then introduced into the separation tank;

[0025] S4, solvent stratification: add saturated sodium carbonate solution to the separation tank, after the shock layering, t...

Abstract

The invention discloses a solvent separation method of a plant extraction mixture, and belongs to the technical field of plant extraction.The solvent separation method comprises the following steps that the extraction mixture is added into a concentration tank and heated, evaporated and concentrated, mixed steam flows out of the top of the concentration tank, and a bottom product is an extract; integrally condensing the mixed steam through a heat exchanger, and introducing the condensed mixed steam into a distillation retort; hot water is added into an interlayer of the distillation retort, the organic solvent is evaporated and separated from the water, solvent steam flows out of the top of the distillation retort, and the solvent steam is introduced into a separation tank after being condensed through a heat exchanger; adding a saturated sodium carbonate solution into the separation tank, oscillating and layering, introducing a bottom mixed solution into a rectifying tower, and sucking an upper liquid into an ethyl acetate collection tank under negative pressure; and feeding the obtained mixed solution into a rectifying tower, and rectifying, concentrating and separating to obtain the ethanol solvent.

Description

Technical field [0001] The present invention relates to the field of plant extraction technology, specifically a solvent separation method for plant extraction mixtures. Background [0002] With the development of science and technology, people's demand for food is no longer a primary demand, such as: flowers, citrus, tea, coffee and fruits, etc., after it is crushed, beaten into a pulp, through the solvent extraction of their beneficial ingredients extracted out, made into high-grade food, health care products, drugs, for our use, in the extraction, often use ethanol and ethyl acetate for extraction, after extraction, the need to separate the organic solvent in the mixture, and the existing separation method is the organic solvent as a whole, After separation, the solvent is in a mixed state, and it is difficult to collect and reuse after separation alone, so we propose a solvent separation method for plant extraction mixtures to solve the above problems.
