botanical extraction machine

The botanical extraction machine is a device that combines effective ingredient extraction, liquid-phase separation, vacuum low-temperature concentration, and solvent/aromatic oil recovery. It is designed specifically for industries such as traditional Chinese medicine, health products, food, cosmetics, and biopharmaceuticals. It replaces traditional segmented processes such as separate extraction tanks and independent concentrators, significantly shortening the process, reducing material loss, and improving the retention rate of thermosensitive components such as polysaccharides, vitamins, and volatile oils. The mainstream models have covered all scenarios from laboratory small-scale testing (50L), pilot testing (100-500L) to small and medium batch production (1.5 ton level)

configuration structure

The botanical extraction machine is "to exchange efficiency through integration, maintain activity through low temperature, and control safety through sealing" - it is not simply assembled, but through process coupling (such as hot reflux+vacuum concentration linkage) and structural innovation (such as concentrated energy ultrasound+uniform stirring), while ensuring the integrity of the components, it can increase the extraction rate by 50-500% and reduce energy consumption by 30-80%

Technical Principle
Extraction stage
Dynamic countercurrent circulation: The solvent penetrates the raw material layer from top to bottom in the extraction tank, and the effective ingredients are efficiently dissolved out
Ultrasonic assisted: cavitation effect destroys plant cell walls, increasing extraction rate by 50-500%
Concentration stage
Vacuum low-temperature evaporation: Evaporate under reduced pressure at 40-60 ℃ to protect thermosensitive components
Secondary steam utilization: Evaporative steam is used as the extraction heat source, saving energy by more than 50%
Advantages 
Efficiency improvement
80% reduction in extraction time (traditional process takes 24 hours → all-in-one machine only 4-7 hours)
Increase the extraction rate of active ingredients by 30-50% (such as soy protein from 28% to 42%)
Energy-saving and environmental protection
Reduce solvent usage by 30% and achieve a recovery rate of over 70%
Reduce wastewater emissions by 80% and support filtrate recycling
Quality Assurance
Low temperature concentration to retain active ingredients (such as reducing the loss rate of vitamin C to below 5%)
Fully enclosed design, compliant with GMP/FDA standards
Intelligent operation
One click start of the entire process, supporting storage and traceability of process parameters

process flow
The integrated plant extraction and concentration machine integrates extraction, filtration, concentration and other processes to achieve continuous production. The typical process is as follows:
Preprocessing and feeding
The raw materials are crushed (such as crushers or crushing rollers) to increase the contact area.
Inject the solvent (water, ethanol, etc.) into the extraction tank through the feeding tube in proportion.
Extraction stage
Dynamic countercurrent extraction: The material and solvent flow in reverse, and high-temperature/ultrasonic assisted wall breaking (such as ultrasonic focusing technology) accelerates the dissolution of active ingredients.
Hot reflux design: The extracted liquid vapor is liquefied by a condenser and refluxed to the extraction tank, reducing solvent loss and improving extraction efficiency.
Filtering and Separation
The crude extract is filtered through ceramic membranes or molecular sieves to intercept large molecular impurities (such as polysaccharides and proteins), with a flux attenuation rate of less than 5%.
The residue is automatically discharged into the receiving basket through a tilted filter plate to avoid blockage.
Concentration stage
Vacuum low-temperature concentration: to avoid high temperature damage to active ingredients, secondary steam recovery is used for front-end extraction of heat energy.
Solvent recovery and cleaning
Ethanol and other organic solvents are recovered through a condenser with a utilization rate of over 50%.
CIP intelligent cleaning system (citric acid/NaOH alternation) ensures membrane flux recovery rate ≥ 95%
