Vertical Extractor Tank

Vertical extractor is a tank that used for water/solvent base extraction of many kinds of herbs.


Product Features


The equipment is applicable to the operations such as decoction of plants and animals at normal pressure and high pressure, warm soaking, hot reflux, forced circulation, percolation, aromatic oil extraction and organic solvent recovery in pharmacy, biology, beverage, food, chemical industry, etc.

It is especially suitable for dynamic extraction or counter-current extraction, with short operating time and a high liquid medicine content.


The tank body is equipped with the CIP automatic rotary spray cleaning ball, thermometer, pressure gauge, explosion-proof sight lamp, sight glass, quick-open type feeding inlet and etc., ensuring easy operation and complying with the GMP standard.

The contact part is made of imported 304 or 316L.



Complete set supply of the equipment

Extraction tank, defoamer, condenser, cooler, oil-water separator, filter, cylinder console and other accessories.

Rotary type & Large-diameter residue discharging door

The tank cover can be automatically opened and closed. High temperature and high pressure extraction can be realized, and more than 3Bar can be achieved in the swivel type product.

It provides more selection for extracting technology.  It can also meet some special technological requirements.

With good safety and reliability, it has sufficient safety guarantee functions and the extracting tank has no leakage.



Filtering method Cylinder side & bottom drain door filtration

For the liquid with high viscosity and difficult to be filtered, the tank side filtering method  will be used.

The strainer is installed on the cylinder wall and the medicinal materials will not press and paste on the filter net, so the filter is more unobstructed.

The filter is a long hole – shaped stainless steel mesh with laser glazing. The bottom of the filter using two layers, lower support mesh, upper stainless steel mesh board, net board covered with 0.6×10mm long hole, compared with mat woven mesh, long hole mesh board is more difficult to block, filter unobstructed, stainless steel polishing durable for 6-8 years do not replace.


Multi-function vertical extraction tank is wildly used for liquid-solid extraction of medical plants, mushrooms, coffee, herb oils and such plants. It is designed, manufactured and inspected in accordance with the pressure vessel standard (GB150-2011) and the steel welded atmospheric pressure vessel standard (NB/T 47003.1-2009), strictly meeting GMP certificate requirements, if jacket is heated by pressured steam, AMSE or PED will also be applied.

316 Extraction tank can be used as mushroom extraction tank, coffee extraction tank and herbs extraction system. Agitator or jacket type (tank body and the bottom head is equipped with the jacket and insulation layer) can be customized. Inner wall of tank body transition section adopts circular arc transition, no dead corner, easy to clean. Tank inner wall are mirror polished, meeting the GMP standard.

Multi-function vertical extraction tanks can be designed as positive conical tank, mushroom type tanks, cylindrical tanks, oblique conical tanks and inverted conical tanks according to the customer’s requirements.

Tank size from 2000L~8000L, also it can be designed and customized according to the customers’ requirements 

  • Pneumatic control self-locking type discharge door ensures no leakage and it is fast and safe under the sudden electricity off and gas off 
  • Connector uses tri-clamp, inner tank use SS304 or SS316L, the inner surface mirror polishing Ra≤0.28 µ m~0.6 µm. Outer Surface can be polished, wiredrawn, sandblasted according to customer’s requirement


Suitable for load, chemical industry atmospheric, decoction, wet leaching, heat reflux, forced circulation penetration, aromatic oil extraction, herbal oil extraction machine and organic solvent recovery especially for Dynamic extraction or counter current extraction, short time and high content of material 

Suitable for dynamic extraction of tea, herbs and other plant leaves with water as solvent medium.

Sanitary grade of SUS304/SUS316L Stainless Steel Vendor: Shanghai Bao Steel Group Corporation or equivalent supplier.

In order to keep the raw materials organized and make sure proper material will be used, we insist asking the material vendor to provide original material test report. Also, we will do in-coming tests to ensure the material is qualified:

  • Metal spectrum analyzer
  • Thickness gauge
  • Roughness detector

All designing, manufacturing and inspection processes are performed according to GB150-1998. ISO9001 Quality Management System Standard will also be applied throughout the entire manufacture process.

Yes, with our certified workshop and excellent welding technics, we can provide you with high quality ASME or PED pressurized equipment.

As multiple tests and inspections are required, lead time of such equipment is longer than normal pressure equipment, it usually takes 18 to 20 weeks to finish.

Plasma welding machine imported from Germany will be used for tank longitude and girth welding and fillet welding to make sure the welding seam smooth and even.

Also, GTAW welding technology will be applied, inert gas concentration is 99.999%. Different welding wire ER316L or ER308 will be applied for different material of SS plate.

For particular circumstances, electric-arc welding will be applied. Welding material used for:

S304-S304: A102; S316L-S316L: A022; Different SS: A302.

Welding seam between jacket and vessel shall be NDT inspected according to JB4730-94 to ensure the impermeability and long service life.

For single tank, it takes around 3-5 weeks to deliver.

For integrated systems, it normally takes 18 to 20 weeks to deliver.

ASME/PED certified equipment will take 18 to 20 weeks

Plastic wrap film should be applied around the entire equipment.

Electrical parts should be disassembled and packed in crates if possible, otherwise it should be fully protected from water or any kind of potential damage in shipping.

Tank will be put down and sitting on a CS frame support, steel wire will be used for fasten tank to support. Rubber should be applied to where steel wire is touching the equipment.

When fixing the equipment in container, multiple fixing belts and/or steel wires should be used to make sure no movement of equipment.

should be used to make sure no movement of equipment

Yes, we will.

Equipment will be thoroughly washed before packing. Water used for washing should not have chloridion content more than 25mg/L to avoid damage of stainless-steel surface. Water stains must be cleaned once washing is finished.
