Structural characteristics of multifunctional traditional Chinese medicine extraction tank
Date: 2025-06-04Read: 62
The structural design of the multifunctional traditional Chinese medicine extraction tank integrates multiple innovative technologies, aiming to improve extraction efficiency, operational safety, and applicability. The main structural features are as follows:
1、 Tank structure and filter system
1. Double layer filter design: At the flow section above the discharge port, a flat mesh lower filter and an upper convex spherical upper filter are sequentially set up, and the mesh size of the upper filter is smaller than that of the lower filter. This design can achieve efficient separation of drug solution and residue simultaneously, avoiding difficulties in discharge caused by blockage and significantly improving extraction yield.
2. The tank forms are diverse, including regular cone, inclined cone, straight tube, mushroom shaped, etc. Modern improved models (such as straight cone and mushroom shaped) adopt a bottom flange with the same diameter as the cylinder design, increasing the liquid outlet area and solving the problem of traditional conical tanks being prone to clogging and requiring manual assistance during slag discharge.
3. Continuous countercurrent leaching structure: Some tanks adopt a slanted horizontal single tank series design, and each single tank is connected through an inlet/outlet to form a connector, achieving continuous countercurrent extraction and improving solute dissolution efficiency.
2、 Heating and circulation system
1. Composite heating method: jacket heating combined with bottom heating, eliminating the dead corners formed by the lack of heat sources at the bottom of traditional tanks, ensuring uniform heating of medicinal materials; The bottom heat source is dedicated to maintaining a slight boiling state and reducing the risk of secondary steam carrying drug residues.
2. Cycle optimization design: The inlet adopts a tangential injection method to inject solvent, accelerating the infiltration of floating medicinal materials and improving extraction efficiency. Forced circulation dynamic extraction (through a circulation pump) can further enhance component dissolution.
3、 Sealing and safety devices
1. Hydraulic driven integrated filter screen: The funnel structure and the upper and lower filter screens adopt an integrated design driven by hydraulic rods, avoiding direct contact between operators and drug liquids and residues, ensuring safety.
2. Self locking slag gate: After the main cylinder is closed, it is supplemented by rotating and pressing technology to enhance sealing and prevent leakage.
3. Auxiliary safety components: equipped with demister to prevent foam from entering the condenser, pressure relief device to control pressure fluctuations, explosion-proof sight lights, mirrors and other monitoring facilities.
4、 Material and Cleaning Design
1. Food grade material: The inner wall of the tank body is made of SUS304/316L stainless steel, mirror polished (Ra ≤ 0.4), and the outer wall is brushed to meet GMP hygiene standards.
2. Online cleaning system: Integrated CIP cleaner, supports online cleaning/sterilization (CIP/SIP), ensuring no residue and easy operation.
5、 Integration of supporting components
1. Multi functional module: The main tank is linked with components such as condenser, oil-water separator, foam catcher, cooler, etc., supporting various processes such as water extraction, alcohol extraction, volatile oil extraction, solvent recovery, etc.
2. Condensation reflux device: The secondary steam is condensed and refluxed to the tank as a solvent, reducing energy consumption and solvent loss.
