“PureyMech’s Centrifuge Extraction Modular System is a stainless steel CBD extraction machine specially designed for hemp oil extraction using low temperature ethanol as solvent. It is a closed-loop CBD extraction machine, more than 97% of solvent will be recovered from evaporation.

It’s composed by pre-chilling tanks, extraction centrifuges, filters, pre-heating tank, falling film evaporator, decarb tank and vacuum station.

Fresh ethanol feeding into Pre-chilling tank to be chilled to -50Co. Loading cannabis into filtration bag and putting into centrifuge before pumping cold ethanol into centrifuge.

Turn on the centrifuge, using HMI screen to control. Spinning out ethanol extracts and remove wasted materials from centrifuge.

Multiple filters will be applied to those ethanol extracts and then feeding into pre-heating tank to get warmed up before entering evaporator.

Ethanol extracts solution will become thin film in the Falling Film Evaporator to ensure the efficiency of evaporation and ethanol recovery.

After ethanol being evaporated, extracts solution turned into thick paste and then be decarbed in the Decarb Tank for decarboxylation processing.

The final product comes out from CEMS is black crude CBD oil known as Full Spectrum oil. 

All sections are modularized and pre-installed on Skids with wheels which allows our client to easily put those them into different rooms or adjust orientation in using.

Pre-chilling section, Centrifuge Extraction section, Filtration Section, Evaporation Section and Concentrator/Decarb section are the sections that will have potential ethanol volatiles in the air, thus it is crucial to have all electrics of the room where those sections be installed in to be explosion-proof.

Facility footprint and budget are the most prevalent constraints when designing Ethanol Extraction Systems.

PureyMech works hand in hand with clients’ and our engineers to design competitively priced ethanol extraction systems based on our clients’ desired processing capacity.

Whether you need a complete turnkey hemp extraction system designed or are just looking to fill in any gaps in your existing cannabis extraction equipment, PureyMech’s modular stainless steel CBD extraction equipment is always your first choice.
