Just for you

Design philosophy:

Equipment performance optimization, good operability, energy saving and environmental protection, overall beautiful.


The equipment is made up with tank, defoamer,condenser, cooler, oil-water separator, oil receiver, duplex strainer, pump and pipeline.


The tank is equipped with CIP cleaning automatic rotating spray ball, temperature gauge, pressure gauge, explosion-proof sight glass lamp, sight glass, quickopening feeding port, etc., to ensure easy operation and meet GMP standards. The inner cylinder of the equipment is made of 304 and 316L.

Operating principle:

Solvent is added into the extraction tank. After soaking,solvent will be heated through steam in the jacket. Medicine liquid will boil in the tank. According to different boiling points of solvent,low boiling point components start to first boil into secondary steam, then through condensation, cooling to oil and water separate. Reflux or discharge can be determined according to process conditions. The oil-water separator uses the different density of oil and water to carry on the upper and lower layers, so as to obtain the volatile oil. In addition, due to a difference in the concentration of medicine liquid in the upper, middle and lower parts of the main tank in the heating process, it can make medicine liquid from the bottom of the main tank through the filter and pump back to the upper part of the main tank for circulation, to achieve dynamic extraction.

    • Food industries
    • Medical industries
  • What Are The Extraction Methods Of Herb Extraction Machine?
  • These include:

  • Maceration
  • Here, you will place the entire or relatively powdered crude herb in a container that has a solvent. Then you place a stopper on the container and allow the mixture to remain at room temperature.
    Allow this to stand for a minimum of 3 days while frequently agitating the mixture till it all dissolves together. Thereafter, strain the mixture and press the marc [damp solid substance].
    After the mixture stands for a while, you will clarify it by filtration or decantation.

  • Decoction
  • Here, you will boil a specific amount of crude herb in water for a specific duration. After this, you will cool and strain or filter the solution.
    Besides, decoction is suitable when you are extracting constituents that are water-soluble and heat-stable. Also, you will use decoction methods when you are preparing extracts of Ayurvedic.
    They are also known as “quath” or “kawath”. In this process, the beginning ratio of the crude herb and water is known, for instance, 1:16 or 1:4.
    Thereafter, this volume comes down to one-fourth the original or starting volume through boiling in the extraction process. After this, you will filter and use the concentrated product as it is or process it further.

  • Percolation
  • This is a common procedure that you will use for the extraction of active ingredients when preparing fluid extracts and tinctures. A percolator is a narrow vessel that has the shape of a cone on both ends.
    First, you will moisten the solid ingredients in menstruum then allow it to stand for an average of 4 hours. Also, make sure you properly seal the container then pack the mass and close the top part of the percolator.
    Besides, you will also add some extra menstruum which will form shallow layers above the mass. Then, you will allow the mixture to macerate for 24 hours in the enclosed percolator.
    After this time, you will open the exit of the percolator then allow the liquid inside to drain slowly.
    Also, you can continue adding menstruum. This is to ensure the percolate measures three-quarters the amount of final product you require.
    Thereafter, you will press the marc and add the liquid to the percolate. Also, add sufficient amounts of menstruum to produce the suitable volume.
    Then you will use filtration or a standing process, then decant the liquid mixture.

  • Infusion
  • In this process, you will prepare fresh infusions through the maceration of crude herbs for a short time. Also, you will use boiling or even cold water in this process.
    They are dilute solutions of the constituents of crude herbs that are readily soluble.

  • Digestion
  • This is also a method of maceration where you will apply a gentle amount of heat during the extraction process.
    Also, you will use the digestion method when a slight increase in temperature is not objectionable. By doing this, the efficiency of the solvent menstruum will increase.

  • Soxhlet/ Hot Continuous Extraction
  • Here, you will add a fine powder of the crude herb in a porous bag or a thimble. The thimble composes of a strong filter paper.
    Then you will heat the extracting solvent then condense the vapor. The vapor that condenses then drips inside the thimble that has the crude herb thereby extracting it through contact.
    Once the liquid level rises above the siphon tubes, it moves into the flask. The process continues until no residue forms on the siphon tubes when evaporating.
    This method has an advantage over other methods because you can extract large amounts with a small quantity of solvent.
    Small-scale industries use it for batch processes only. However, large-scale industries can use it as it is economical when you convert it to a continuous extraction process.

  • Fermentation Through Alcoholic Aqueous Extraction
  • This method entails soaking the crude herbs for some time. During this process, it will ferment and generate alcohol in situ which facilitates the extraction of active ingredients.
    The alcohol that forms will serve as a preservative. In instances you are planning the fermentation on earthen vessels, make sure it is not new.
    Also, boil water in the vessel before using it. Large industries use metal vessels, wooden vats, or porcelain vats in place of earthen vessels.

  • Counter-Current Extraction
  • Here, you will produce fine slurry by pulverizing wet raw materials in toothed disc disintegrators. Also, the product moves in one direction inside the cylindrical extractor as it comes into contact with the solvent.
    The extract will have more concentration the more distant the starting substance moves. When you optimize the flow rate of the material and the amount of solvent, you will achieve complete extraction.
    Besides, the method is efficient and takes less time while posing no danger when the temperatures are high. Extract in high concentration will exit via one end of the extractor and the marc exits from the other exit.

  • Supercritical Fluid Extraction
  • The agenda of this method is to lower the use of organic solvents and increase the sample throughput. Important factors to consider include pressure, modifiers, temperature, restrictors, sample volume, and analyte collection.
    Some of the other methods include:

    • Reflux Extraction
    • Pressurized Liquid Extraction
    • Microwave Assisted Extraction
    • Pulsed Electric Field Extraction
    • Enzyme Assisted Extraction
    • Hydro And Steam Distillation
  • Which Are The Common Solvents Used In Herb Extraction Machine?
  • These solvents include:

    • Polar solvents like water and alcohol.
    • Intermediate polar solvents like acetone and dichloromethane.
    • Non-polar solvents like chloroform, ether, and n-hexane.
  • What Are The Key Factor To Consider When Selecting Extraction Solvent For Herb Extraction Machine?
  • These include:

  • Immiscibility
  • The solvent should be immiscible with the solution you want to extract. Also, the more polar an organic solvent is, the more it is soluble with water.
    Organic solvents that have low polarity are suitable as organic extracting solvents.

  • Solubility
  • The ingredients you are extracting should be soluble with the extracting solvent. Also, impurities from, I.e. a reaction, should not dissolve in the extraction solvent.

  • Volatility
  • Make sure the extraction solvent is sufficiently volatile. This makes it possible for you to remove it from the extract through distillation.

  • Cost
  • These solvents come in varying price ranges. For instance, water is cheap whereas ether and glycerine are costly.

  • Safety And Toxicity
  • It is suitable when the solvent you are using is non-toxic and is not flammable. However, only a few solvents meet both criteria.
    Non-toxic but flammable solvents include ether and hexane. Toxic but flammable solvents include chloroform and dichloromethane.
    A solvent that is both toxic and flammable is benzene.

  • How Many Types Of Herbal Extraction Machine Are There?
  • These include:

  • Mixer-Settlers Herbal Extractors
  • These are common machines as they are reliable, flexible, and have a high capacity.
    They can handle disperse systems that are hard to handle such as those possessing high interfacial tension.
    Besides, they cope with liquids that are highly viscous and solid-liquid slurry.

  • Pulse Herbal Extractors
  • Here, a pump will create short amplitude pulses that overlap the normal liquid phase flow. The column may have packing or plates with perforations.
    It has the advantage of low axial mixing and a low increase in axial mixing that increases within the column diameter. Pulsation causes the liquid to move in the heavy phase during the upward stroke.
    Also, the heavy phase jets into the light phase during the downward stroke.
    Light liquid enters via the bottom part and changes to tiny droplets when it reaches the nozzle distributor. The light droplets rise as the heavy mass moves downwards.

  • Centrifugal Extractors
  • Application of centrifugal force lowers residence time and accelerates phase separation. They are suitable in applications where contact time should be short, for instance, chemically unstable systems.

  • Unagitated Column Herbal Extractors
  • They have two phases that flow in a countercurrent pattern.

  • Mechanically-Agitated Herbal Extractors
  • They assist in improving new droplet formation while increasing interfacial turbulence which causes high efficiency. The two classes here are the rotary-agitated and vibrating-plate column.

    This part is suitable for pumping gas as gas-filled cavities increase and decrease during its revolution.

  • How Does Herb Extraction Machine Work?
  • The stages involve the following:

  • Liquid Solvent Injection
  • Here, you will introduce the solvent from the operating tank to the extraction tank. It then flows to the herb material via a safety hose and extracts the ingredients from the plant.
    The time and pressure this process takes depend on the solvent you are using. The soaking duration is the time the solvent is in contact with the plant substance.

  • Extraction Chamber
  • The herb extract will collect at this part of the machine. Pressure in the system will automatically push the solution via a silkscreen.
    It then moves to the separator then collects in the collection vessel.

  • Collection Vessel
  • Here, a water jacket will evenly apply heat to the solution and the solvent begins to evaporate. As it vaporizes, the pressure builds and forces it out of this system via a valve leaving behind the extract.

  • Expansion Filter
  • The evaporating solvent flows via safety pipes and settles at the bottom of the vessel. A recovery pump will withdraw the solvent from the sieve system through a connector. Also, you can apply heat to hasten this process.

  • Desiccant Filter
  • This part assists in cleaning the vapor from the expansion filter as it moves to the recovery pump.

  • Recovery Pump
  • Pulses will drain the solvent in here and the fumes settle. Then you will discharge it and channel it to the operating tank for recycling.
