Crystallization tank for traditional Chinese medicine extraction

Abstract

The invention relates to a crystallization tank for traditional Chinese medicine extraction. The crystallization tank comprises a crystallization tank body and a crystal seed generation tank, wherein a tank cover is arranged on the crystallization tank body; a plurality of material addition ports are formed in the tank cover; a motor is arranged above the crystallization tank body and connected with a stirring shaft; a plurality of paddles are arranged on the stirring shaft; a first cooling jacket is arranged around the crystallization tank body; a discharge port is formed in the bottom of the crystallization tank body; a second cooling jacket is arranged around the crystal seed generation tank; a plurality of ultrasonic transducers are uniformly arranged on the outer wall of the second cooling jacket; a feeding port and a conveying port are formed in the top and the bottom of the crystal seed generation tank respectively; the conveying port is connected with a conveying pipeline, and the other end of the conveying pipeline extends into the upper part of the crystallization tank body. With the adoption of the crystallization tank for traditional Chinese medicine extraction, the quantity of added crystal seeds and the granularity can be effectively controlled, the controllability of the crystallization process is improved, the quality of produced traditional Chinese medicine crystals is good, the purity is high, the granularity is uniform, and convenience is brought for the following preparation process.

Description

Technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing equipment, in particular to a traditional Chinese medicine extraction and crystallization tank. Background technique [0002] In the process of extracting traditional Chinese medicine, in order to make the active ingredients play their role better, it is usually necessary to extract and recrystallize the traditional Chinese medicine.

[0002] In the process of extracting traditional Chinese medicine, in order to make the active ingredients play their role better, it is usually necessary to extract and recrystallize the traditional Chinese medicine. In order to improve the controllability of the crystallization process and ensure that the crystal size obtained is more uniform, the crystal habit is better or To obtain crystals of a specific crystal form, it is usually necessary to add seed crystals. The quality of seed crystals is directly related to the quality of crystals. Seed crystals have certain requirements for purity, particle size and addition amount. There is a technology that directly installs an ultrasonic transducer on the crystallization tank, stimulates the formation of crystal nuclei through the disturbance of the sound field, and then uses the supersaturation of the solution to provide energy for the growth of the crystal, but after a large number of crystal nuclei are generated, the supersaturation in the solution In the process of crystal growth, some crystals grow fast, while some crystals grow slowly, resulting in uneven particle size of the obtained crystals. At the same time, there may be The phenomenon of crystal agglomeration and agglomeration occurs, so it is urgent to provide a traditional Chinese medicine extraction crystallizer that can provide high-quality seed crystals to ensure that crystals with uniform particle size and high purity are obtained, which will bring convenience to the subsequent Chinese medicine processing technology
