Abstract

The invention discloses a normal temperature high pressure continuous extraction method of active ingredients of natural products, including five steps of crushing, soaking, ultra-fine smashing, high pressure extraction and solid-liquid separation, wherein the material liquid after the ultra-fine smashing is continuously pumped into a high pressure extractor by an underflow pump in the high pressure extraction, the material liquid achieves the pressure of 1 to 90MPa via a high pressure pump, the material liquid is impacted on a collision ring in the high pressure extractor by an annular working gap in the high pressure extractor being subject to the high pressure, and the cells of the natural products in the material liquid is crushed; the five steps are carried out at normal temperature, the normal temperature refers to the temperature ranged from 10 to 45 DEG C, the better temperature ranges from 15 to 40 DEG C, and the best temperature ranges from 15 to 30 DEG C. The invention also discloses a device to realize the method.

Description

technical field [0001] The invention relates to a method and equipment for extracting active ingredients of natural products, in particular to a method and equipment for continuously extracting active ingredients of natural products at room temperature and high pressure. Background technique [0002] Since the late 1990s, natural product extracts have attracted more and more attention from industries such as medicine, food, cosmetics, health care products, and deep processing of agricultural products, and have become one of the fastest-growing industries in China. Commonly used techniques for natural product extracts include reflux extraction, low-temperature immersion or percolation extraction, supercritical CO2 extraction, microwave extraction, ultrasonic extraction, etc., but the technical effects are not ideal, such as: the biological activity and The pharmacological effect is low; the extraction rate of active ingredients of natural products is low, and many valuable na...

Problems solved by technology

[0004] (1) Since the high-pressure extraction mechanism of this method is to simply use ultra-high pressure to squeeze the cells of small molecules in the biological material, and to break the cell membrane to achieve the purpose of allowing the functional components in the cells to enter the solvent, the working pressure is at least several Hundreds of megapascals, even as high as several thousand megapascals, so this method has very high requirements on the pressure resistance and pressure of the equipment, especially when the pressure value reaches the ultra-high pressure range, the equipment needs to use ultra-high pressure vessels, and the equipment cost is high , unbearable for ordinary enterprises;

[0005] (2) The above-mentioned high-pressure extraction operation process is an intermittent operation process. To complete an operation process, it needs to go through the process of boosting, pressure maintaining and pressure relief. There are many links in the working process, and it needs to be repeated for the next operation. The above working process, therefore, the production efficiency is low, which cannot meet the needs of modern industrial continuous production;

[0006] (3) The working process of the above method will go through the process of boosting pressure and maintaining pressure. The cell crushing of small molecules in biomaterials is achieved through the process of maintaining pressure. In order to squeeze as many molecular cell walls as possible, it is necessary to pressurize The process lasts for a long period of pressure holding time, which will lengthen the working time of the entire operation process and greatly affect the production efficiency;

[0007] (4) Since the equipment adopts an ultra-high pressure vessel, the cost of the equipment is very high, and it is difficult to realize large-scale equipment, resulting in a small production capacity. In addition, the operation process of the method is intermittent operation, which greatly reduces its production efficiency, so it is difficult to Carry out industrialization promotion
