Problems solved by technology

However, the reflux extraction method has the following disadvantages and deficiencies: 1. It has certain limitations in the extraction of highly heat-sensitive and easily destructible natural plants; 2. The extraction rate is low and the waste of raw materials is large; 14-18 times the amount; 4. The extraction time is long, generally 5-7h, and the energy consumption is high; 5. The production efficiency is low. Each batch of extraction needs to update the solvent two to three times, and continuous production cannot be realized
[0003] The spray method was only used in material drying in the past, so far there has been no report on the application of high-pressure spray method to the extraction of active ingredients from natural plants

Embodiment 1

[0021] Step 1. Removal of impurities: Taking salvia miltiorrhiza as an example, firstly, 300kg of salvia miltiorrhiza raw materials that have passed the inspection are manually selected to remove impurities;

[0022] Step 2, crushing: putting the natural plants to be extracted after removing impurities into a crushing machine with a built-in 120-mesh screen for crushing;

[0023] Step 3, prepare the material suspension and pass through the screen: put the pulverized natural plant material to be extracted from the raw material box 1 into the No. 1 mixing tank 2 with a built-in agitator, and then pour it into the No. Add soaking solution to the natural plant raw material, the soaking solution is ethanol solution with a volume concentration of 90%, stir and soak for 1.5h, and the stirring rate is 80r / min; the obtained material suspension flows into the No. 2 stirring tank through a 100 mesh screen 3 Stirring in 4 for subsequent use; the volume-to-weight ratio between the added so...

Embodiment 2

[0027] Embodiment two: basically the same as embodiment one, the difference is that the extracted natural plant is licorice, and the extraction solvent is water.

Embodiment 3

[0028] Embodiment three: basically the same as embodiment one, the difference is that the natural plant extracted is rhubarb, and the extraction solvent is 60% ethanol.

Abstract

The invention discloses a device and a method for extracting effective components from a natural plant by a high-pressure spraying reverse-flow process. The method comprises the steps of: after the device is connected, removing impurities of a natural plant to be extracted and smashing, putting the smashed natural plant to be extracted in a stirring pot and adding a soak solution in the stirring pot to obtain material suspension, adding an extraction solvent into the extracting pot, spraying the prepared material suspension to be mist-state drops so as to perform spraying extraction, extracting by a high-pressure spraying reverse-flow, and finally, using a centrifugal machine to remove solid impurities, reducing pressure to concentrate to obtain a product by spraying drying, microwave drying or vacuum drying. With the adoption of the device and the method for extracting the effective components of the natural plant by the high-pressure spraying reverse-flow process, the production efficiency can be obviously improved, the use ratio of the device is improved, a plurality of devices can be used for extracting via a dynamic cycle mode, the extracting process does not need to be heated and is performed at a normal temperature, so that the damage of the effective components in the high-temperature heating process is avoided; and the device is low in investment and running costs.

Description

technical field [0001] The invention belongs to the technical field of extracting active ingredients of natural plants, and in particular relates to a device and method for extracting active ingredients of natural plants by using a high-pressure spray countercurrent method. Background technique [0002] According to the time when the natural plant active ingredient extraction method appeared, the natural plant active ingredient extraction method can be divided into traditional extraction method and modern extraction method. Traditional extraction methods include: maceration, decoction, percolation, reflux extraction and continuous reflux extraction. Modern extraction methods include supercritical fluid extraction, ultrasonic extraction, and microwave-assisted extraction. Due to the large one-time investment of modern extraction equipment, slow investment recovery, high equipment and process technology requirements, and difficulty in popularization and application, at presen...
