DEVEX Verfahrenstechnik GmbH

The DEVEX Cryo Ethanol Extraction System provides the following processes:

• Solvent Cooling
• Ethanol Extraction
• Ethanol Recovery
• Ethanol Stripping out of cannabis biomass after Ethanol Extraction
• Decarboxylation

Due to the use of ethanol for solvent the equipment is designed to match with hazardous environment conditions Ethanol IIB T3, inside zone 1 / outside zone 2 (ATEX II 2G / ATEX II 3G). For the North American market the system is designed to match the conditions NEMA Class I Division 2 (CID2).

The quality of coffee extract is primarily defined by the quality and blend of the coffee bean. This again is related to the specifications of the processing steps, e.g. roasting and grinding, the extraction type as well as aroma recovery and final drying.

DEVEX offers individual process concepts, developed for a maximum operational flexibility in consideration of the final product quality and the required capacity.

During the extraction process, soluble solids and aromas are highly efficiently extracted and the coffee aromas are gently obtained to achieve the desired aroma profile. The extraction process is then followed by the clarification of the coffee extract. Afterwards, the extract is concentrated under vacuum at gentle temperatures. The generated aromas are then mixed with the extracted concentrate to adjust to required flavor. This standardized aromatic coffee extract can either be bottled or spray or freeze dried.

In the freeze drying process the coffee extract is first of all frozen and afterwards fed to a milling and sieving system in order to obtain the desired grain size. The freezing tunnel, in which the coffee extract is frozen, is a DEVEX in-house development and can be used for many more products.
