Chinese Medicine Extraction Tank

1. The extraction tank is made of internationally  stainless steel 304 or 316L. For higher – level requirements, it is made of duplex stainless steel 22205 or titanium materials. It has the characteristics of smooth and clean inner and outer surfaces, no material adhesion, and no material accumulation. It is the preferred equipment for factories with high sanitary level requirements in the pharmaceutical and food industries.
2. Extraction tanks with a volume of less than 500L can be configured with two structures, with or without a container flange, according to the presence or absence of a stirring system. Those with a stirring system adopt stainless steel container flange connections, facilitating the installation of stirring and lifting for maintenance. Static extraction tanks without a stirring system adopt a welded structure, with a manhole provided for convenient feeding. Extraction tanks with a volume of 500L and above generally adopt an upper – lower welded structure. The upper part has a feeding port, and the lower part has a large slag discharge door. This kind of pilot – scale extraction tank is generally equipped with a DN400 or DN500 manhole, allowing access for installing stirring or maintenance. The interior of the tank is fully precision – polished, with no sanitary dead corners, meeting the pharmaceutical GMP standards.
3. The head form of the extraction tank is generally an upper elliptical head and a lower conical bottom, and the slag discharge door is a spherical – crown – shaped head. This style is aesthetically pleasing, with a smooth transition inside the tank, and a relatively high sanitary level.
4. The stirring form of the extraction tank can adopt various forms such as paddle stirring, anchor – type stirring, frame – type stirring, anchor – paddle combined stirring, frame – paddle combined stirring, and spiral – type stirring according to process requirements. The user unit can select one or more stirring forms according to the characteristics of the materials and the operating conditions. Our company has been focusing on the design and manufacturing of stainless steel extraction tanks for many years and has rich experience. Our extraction tanks can ensure meeting the users’ usage requirements.
5. Other configurations of the extraction tank can be optionally equipped as needed, such as cleaning, metering, number of nozzles, sealing forms, etc. Our company can configure them according to the users’ process requirements.
6. For the selection of extraction tanks, please provide the relevant basic requirements such as material characteristics, operating temperature, operating pressure, and rotation speed. Our company can design and manufacture according to needs. Welcome to call for consultation and negotiation.
7. A complete set of extraction tank equipment is mainly composed of seven parts: the main tank (extraction tank body), demister, condenser, cooler, oil – water separator, filter, and pump. The extraction tank is the main tank and the main body of the extraction reaction. The decoction, heating, cooling, evaporation, and reflux of raw materials are realized inside the extraction tank. Extraction tanks generally use a slag discharge door for discharging, which is convenient, fast, and safe. A quick – installation cover is set on the top of the demister to facilitate the disassembly of the defoaming component. The built – in defoaming component is easy to disassemble and clean. Condensers, coolers, vapor – liquid separators, filters, etc. are designed according to actual conditions, such as operating pressure, heat exchange area, shell wall thickness, and tube specifications.

The main factors to be considered for the selection of extraction tanks are as follows:
(1) Material characteristics: Such as viscosity, density, water absorption, volatility, corrosiveness, etc. Special instructions should be given if the materials have special properties.
(2) Operating conditions: Operating temperature and operating pressure
(3) Comprehensive technical conditions: Heating time, processing time, requirements for the control system, description of process nozzle configuration, factory conditions, and explanations of water, electricity, and gas conditions.
