Features of multifunctional extraction tank

1Features of multifunctional extraction tank：

The extraction tank is mainly used for the process of decoction extraction and hot reflux extraction of Chinese medicinal materials in a stirred state using water or organic solvents as the medium. And the volatile oil components can be recovered simultaneously during the extraction process. The extraction tank has high efficiency in extracting effective ingredients from large quantities of medicinal materials; Energy conservation, more complete extraction of effective ingredients, and higher drug concentration in the extraction solution. Working principle: The entire extraction process of the extraction tank is completed in a closed and recyclable system, which can be extracted under normal pressure or with low pressure. Whether it is water extraction, alcohol extraction, oil extraction or other purposes, the specific process requirements are determined by the Chinese medicine factory according to the drug performance requirements.

2、 Extraction principle of extraction tank:

As the name suggests, an extraction tank is used to increase the purity of materials and extract effective substances. Therefore, some purification tanks are also called purification tanks. This is a different name for purification tanks used in different industries, with similar functions and characteristics as purification tanks. The principle of common purification tanks:

1. Such as water extraction: Water and traditional Chinese medicine are loaded into a purification tank according to a certain process ratio, and the interlayer heat source (with a jacket) is started. After boiling in the tank, the supply of heat source is reduced, and the slight boiling in the tank is maintained. According to the extraction pharmacological process, it is maintained for a certain period of time to ensure that the effective ingredients in traditional Chinese medicine or Chinese medicine decoction pieces are fully dissolved in water.

2. Like alcohol extraction: First, add the medicine and alcohol into the tank according to a certain process ratio to keep the system in a closed state, and provide the interlayer heat source (with a jacket). When the temperature inside the tank reaches the required level, reduce the supply of heat source to maintain the temperature inside the tank at the required process temperature for a certain period of time, ensuring that the effective ingredients in traditional Chinese medicine or herbal medicine slices are fully dissolved into the alcohol. The rising vapor state alcohol is condensed by a condenser to form liquid alcohol, which is then stored and reused after distillation and purification; To improve efficiency, a pump can be used for forced circulation, allowing the liquid medicine to be sucked out from the bottom of the tank through the pump and then imported back into the tank from the top.

3. Oil extraction: First, add the Chinese medicine and water containing volatile oil into the purification tank according to a certain process ratio, supply the jacket heat source steam (with jacket), after reaching the volatilization temperature, adjust the amount of steam entering, and maintain the temperature in the tank for a certain time according to the process requirements. The volatile aromatic oil can be cooled through the cooling system, and the cooled liquid medicine can be separated through the oil-water separator.

4. Recycling oil essence: Add alcohol to the cylinder, open the cooling water for steam, and then open the recycling valve.

3、 Selection criteria for extraction tanks:

The main factors to consider when selecting extraction tanks are:

Material characteristics: such as viscosity, density, water absorption, volatility, corrosiveness, etc. If the material has special characteristics, special instructions should be given.

Operating conditions: operating temperature, operating pressure

Comprehensive technical conditions: heating time, processing time, requirements for control system, instructions for process pipe fittings, factory conditions, and description of water, electricity, and gas conditions.

4、 Multi functional extraction tank selection parameters:

5、 Quality standards for extraction tanks:

The extraction tank can be designed, manufactured, and inspected according to the following standards:

1. SFDA "Good Manufacturing Practice for Drugs" 2010 edition

2. Design Specification for Cleanrooms in the Pharmaceutical Industry (GB50457-2008)

3. GAMP Drug Production Automation Management Specification

4. GB150.1~150.4-2011 "Steel Pressure Vessels"

5. NB/T47003.1-2009 "Steel Welded Atmospheric Pressure Vessels"
