Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery and equipment technology, specifically a multi-stage countercurrent dynamic extraction unit for traditional Chinese medicine. Background Technology

[0002] Multi-stage counter-current dynamic extraction units for traditional Chinese medicine are mechanical devices and equipment used for processing medicinal raw materials. Pharmaceutical machinery refers to mechanical equipment used for drug production, inspection, and packaging, and is one of the most basic facilities in pharmaceutical companies. This equipment covers the entire drug production process from raw material processing to finished product packaging, and includes: granulation ovens, fluidized bed dryers, wet processing machines, pulverizers, slicers, stir-frying machines, decoction machines, tablet presses, pill making machines, multi-functional extraction tanks, storage tanks, mixing tanks, vacuum drying ovens, tilting reaction vessels, capsule filling machines, blister packaging machines, granule packaging machines, powder packaging machines, V-type mixers, and lifting feeders, etc.

[0003] Utility model patent CN202822848U discloses a tank-type progressive separation ultrasonic countercurrent continuous extraction unit, mainly composed of a screw feeder and a multi-stage tank-type unit assembly connected to it, as well as auxiliary assemblies used in conjunction with the multi-stage tank-type unit assembly. It integrates continuous percolation, dynamic extraction, ultrasonic extraction, multi-stage separation, and progressive continuous countercurrent extraction. During the extraction process, through multi-stage repeated dynamic stirring, extrusion and kneading, and high-frequency ultrasonic oscillation, it enhances the relative movement between the powdered raw medicinal materials and the liquid solvent, as well as the solvent penetration, resulting in faster solute diffusion, more thorough extraction, and more complete extraction of the effective components of the medicine. This effectively improves solvent utilization and the extraction rate of the effective components of the medicine. This unit not only has a reasonable structural design, is easy to operate and maintain, but is also highly efficient and energy-saving. Furthermore, it can achieve a fully enclosed system and continuous automated production throughout the extraction process. It is a widely applicable modern Chinese medicine extraction equipment.

[0004] Currently, most Chinese medicinal materials are directly fed into the pharmaceutical extraction tanks of pharmaceutical processing units. After the pharmaceutical process is completed, the residue is not easy to discharge, and the discharge port is easily blocked when the residue is discharged. Moreover, the discharge efficiency is slow, which affects the pharmaceutical efficiency. At the same time, when the liquid medicine is transported through the conveying pipe, small impurities in the liquid medicine will be discharged along with the liquid medicine. Over a long period of time, these residues can easily block the conveying pipe and also affect the purity of the liquid medicine, thus affecting its use. Utility Model Content
