Solvent Extraction System

Clean Green Biosystems offer turnkey solvent extraction system for phyto cannabinoids extraction from dry cannabis material. The solvents shall be ethanol, hexane, chloroform or ethyl acetate.


Clean Green Biosystem is having vast expertise in supplying turnkey phytocannabinoids extraction systems, that include detailed engineering design, (both process design and equipment/fabrication design), assembly, installation, erection and commissioning. We have executed various extraction systems in India and abroad. We supply the turnkey projects to our clients based on their requirements. All our supply is customized to clients needs. Our scope supply of the phytocannabinoids extraction system is based on Solid-Liquid Extraction (SLE).


Our SLE, systems are capable of extracting phytocannabinoids from cannabis and hemp.



Our both SLE systems can handle solvents and solvent systems such as water (aqueous extraction), methanol, ethanol, acetone, hexane, ethyl acetate, petroleum ether, di ethyl ether etc (Solvent extraction).


The following is the generalized process design adopted by Clean Green Biosystems

The process design of Clean Green Biosystems to extract phytocannabinoids is as below.


Extraction System:

Our extractors are of different types., viz., agitated, recirculation, rotary. We select and recommend the extractors as per the process needs. Our extractors are suitable for both hot process (using steam) and cold process (using cryogenic medium). Our extractors are integrated with a unique desolventization system, which ensures the maximum recovery of solvents and safe disposal of spent materials. Our extractors are having bottom opening (both manual and automatic) for the discharge of spent materials.


Our extractors are designed and fabricated as per ASME standard codes. The electrical components in the extractors conform to all international standards. Country specific electrical components are integral part in the supply.


The extraction efficiency of our extractors is 98%.


Our extraction systems are designed in such a way that it gives a high recovery of phytocannabinoids extracts using optimum solvents levels, lesser extraction time and lesser solvent loss (maximum solvent recovery).


Filtration System:

The filtration system is optional as we already have integrated filter in the extractor itself. We normally supply plate and frame filter press. The numbers of filter plates vary on the basis of the volume of miscella to be filtered. The filter plates can be PP or SS.


For small volume filtration, we supply zero hold up filter press.


Distillation And Concentration System:

We use multiple effect evaporative systems using a LOW TEMPERATURE SHORT CONTACT DISTILLATION PATH. Hence the extracts produced are of having intact phytocannabinoids with high concentrations of various CBD and THC fractions in the extracts. The thermal degradation is completely avoided.


CGBS offers the distillation and concentration system with a unique and proprietary integration of forced circulation evaporation and molecular distillation systems. The number of stages of forced circulation evaporation depend on the volume of miscella to be evaporated. Our LTSCDP is integrated with secondary condensers for maximum recovery of solvents. This is achieved by applying chilled water.


Drying System:

Clean Green Biosystems offer Vacuum tray driers, rotacone driers, ribbon driers of various capacities. We supply suitable vacuum systems for the driers.


Downstream Processing System:

Clean Green Biosystems offer downstream processing systems to produce various fractions of CBD. The down stream processing equipments like column chromatography, ANFD, crystallizer, fractionation columns, washing columns, separating columns, pulverizers, mixers, blenders and rotary evaporators.


Clean Green Biosystems also offer preparatory equipments such as pulverizer, pelletizer, etc.


Clean Green Biosystems also offer, material conveying systems for charging the dry cannabis/hemp material into the extractors (conveyer, load cells, rotary valve etc) and spent material conveying systems.


We support our clients with the operation manuals of the supplied plants, SOP’s and maintenance services. Also, we impart training of the technical staffs of our clients during and after the commissioning of the plants.
