professional laboratory and pilot plant for research and development.
Professional laboratory and pilot plant for research and development, there is a small area to clean, suitable for multi-tank group of counter-current extraction, can also be set separately to extract a single tank.
Technical advantages:
1 Solvent is small, the follow-up process significantly reduces energy consumption, lower production costs
2 Continuous operation, greatly improved production efficiency and ease of automated control
3 Improve the solvent and the concentration difference between the herbs, the active ingredients in the herbs to extract the maximum
4 Measures to accelerate the use of forced circulation spread of the active ingredient
5 Counter-current mode, low temperature operation, will help to keep heat-sensitive active ingredients
Based on the experimental prototype, we enlarge the unit by using the device industry to good effect (3.5T × 6 cans).
Countercurrent extraction with six cans Group units, process and control technology requirements for reference purposes only.
Equipment overview
1, measured after extraction from the extraction medium tank above the feeding ports to join extractor, the solvent from the solvent storage tank via the quantitative plate heat exchanger to extract pre-heat pump into the tank, open the extracted steam jacketed tank valve and open the circulation pump, through steam control valve to control the temperature of the extraction process, through the programmable logic controller and programmable expansion module to control the circulation pump and the extraction time on the set and controlled by pneumatic control diaphragm to extract the location of migration, to achieve manufacturing extract and complete the extraction process gradient.
2, extract after extract phase by extraction tube wall and bottom of the tank filter (a filter 60 mesh) and the duplex filter (secondary filter 80 mesh) extraction process is complete.
The technical introduction
Name | Six cans Group countercurrent extraction unit |
Structural | Inverted cone extractor structure; with demister, condenser, cooler, water separator, the head nominal size DN1100mm; feeding door pneumatic wafer butterfly valve, nominal size DN300mm; slag door pneumatic quick-open structure, Nominal size DN1500mm; extractor jacket and insulation with a cellular layer, insulating layer outsourcing using 2mm stainless steel plate; cylinder thickness 8mm |
Performance | Extractor according to pressure vessel design, production; equipment, beautiful appearance, convenient operation, reliable sealing; especially the slag door open and flexible, reliable sealing, the slag door open and close without impact. Pipeline, modular extraction tank group unit, each group of cells can be independent of the extraction operations (extraction, dynamic extraction, high-temperature extraction), can also be used in combination (continuous countercurrent extraction stage continuous countercurrent extraction); use effective devices prevent pipeline blockage problem; inverted cone extraction tank, reasonable structure, the slag door opening double protection, leak-free tank bottom; to ensure operational safety. |
Material | Equipment shell, jacket, insulation jackets of stainless steel 304; insulation temperature above 140 °C |
Precision | Equipment, mirror polished inner surface (Ra ≤ 0.4μm), the outer surface shot blasting equipment; containers inside and outside weld in need of polishing, internal and external surface roughness Ra ≤ 0.4μm; stainless steel welding standard JB/T4735-91; welded joint type and size in addition to special requirements, according to GB985-88 stipulates that the fillet weld angle equal to the size and thinner thickness; docking at the inner surface of the cylinder does not allow docking marks (not penetration); pipe and connected to the inner cylinder, does not allow docking marks the outer surface does not allow significant build-up welding, butt joints need to smooth the transition, no dead, no effusion, no contamination, in line with GMP requirements; welded joints shall not have cracks, holes, crater, bite edges and other defects. Fillet weld angle to take the high sheet thickness, stiffener (or ring) of fillet thickness 70% whichever is higher, and not greater than its thickness. All butt welds shall be polished flush to the base material; all the fillet to be grinding to a smooth transition of the base metal flush. Within the maximum allowable surface roughness Ra value of 0.4μm, and does not allow scratches, uneven and hammering and other marks. Overall vertical deviation, should not exceed 0.4% of tank height. |
Main configuration Accessories and safety Installation | Equipment on the head DN1100 δ = 8mm, equipment inverted cone diameter top tube 1100mm, bottom diameter of 1500mm, used with cellular jacket, ultra-fine glass wool insulation thickness of 50mm, outer protection plate δ = 2mm stainless steel plate, extraction tank door switch with double lug suspension cylinder, the use of reinforced door lock clamp ring structure to ensure a smooth extraction tank door open and safe. Extraction tank bottom set of laser processing 0.5 X 10mm long hole filter elements, and allocate space and diversion with solvent components, a large area of the filter element to ensure the system's smooth. With demister, 15M 2 condenser, 2M 2 cooler, water separator, the feed door pneumatic butterfly clip on the DN300, each extract can be set separately 10T / H Ex 0.65M 2 Health pump and the Omo secondary filter. Pipeline, modular extraction tank group unit, each group of cells can be independent of the extraction operations (extraction, dynamic extraction, high-temperature extraction), can also be used in combination (continuous countercurrent extraction stage continuous countercurrent extraction); standardization of all process automation, automatic temperature control (steam control valve) and extraction time. Plate heat exchanger through 8M2 solvents measured by adding, pneumatic door. Reserved for PH (optional), flow rate (optional), and other key process parameters of auto-sensing interface, a continuous extraction process to ensure the stability and reliability; with near-infrared detection system online access point for counter-current extraction process traditional Chinese medicine active ingredients of the real-time measurement, to facilitate optimization of process parameters. |
