Description

High-efficiency extraction device for extracting active ingredients of plants

technical field

The utility model belongs to the field of chemical extraction equipment, in particular to extraction equipment for improving the extraction efficiency of natural plant raw material active ingredients.

Background technique

In the prior art, natural plants and Chinese herbal medicines are increasingly used in various fields such as medicine, food, and spices, and the extraction of active ingredients from natural plant materials is an important method and link. At present, natural plants are mainly extracted by heating with organic solvents. This method is not efficient, consumes a lot of time and energy, and often not only causes damage to heat-sensitive components in plant materials, but also brings out many impurities, which increases the subsequent separation. The purification process increases consumption and production costs. Ultrasonic extraction technology is the use of ultrasonic special strong longitudinal vibration, high-speed impact crushing, cavitation effect stirring and heating and other physical properties to accelerate the dissolution of active ingredients, improve the extraction rate of active ingredients, with short extraction time, high yield, non-destructive The advantages of active ingredients, no pollution, etc., are more and more widely used in extracting active ingredients of natural plants and Chinese herbal medicines. Ultrasonic industrial equipment is currently in the development stage. Although there are already commercial equipment and many related patent achievements, there are still many imperfections in general. For example, in patent CN244839Y and patent CN2015585669U, the ultrasonic generator is placed at the bottom of the equipment. The raw materials are easy to settle at the bottom and affect the working effect of the ultrasonic wave. The size of the discharge port is limited and the slag discharge is difficult. Patent CN201333400Y solves this problem better, but this equipment is only equipment with ultrasonic extraction function, and the raw materials need to be pulverized before treatment.

Utility model content

Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a high-efficiency extraction device for extracting active ingredients of plants, which integrates the crushing, extraction and ultrasonic extraction of raw materials, reduces intermediate links, and saves extraction time, reduce production costs, and improve the extraction efficiency of active ingredients in raw materials.

The technical scheme of the utility model is: an interlayer heated by steam is arranged around the tank body of the reaction tank of the high-efficiency extraction device for extracting active ingredients of plants, the inner wall of the reaction tank is provided with an ultrasonic generator, and the center of the reaction tank is provided with Stirrer, the lower end of the stirrer is provided with a stirring blade, the top cover of the reaction tank is provided with a feed port and an exhaust hole, the bottom of the reaction tank is provided with a filter screen and a bottom cover, and the center of the bottom cover is provided with a discharge Tube. The filter screen is 20-40 mesh. The bottom cover is movably connected with the tank body. The diameter of the discharge pipe is 10cm-20cm.

The utility model has the advantages of reasonable design, simple structure, fast and convenient feeding and discharging, high extraction efficiency, short production cycle, multiple extractions in a single batch, and is suitable for large-scale production.
