Timatic FC - a system designed for gas extraction and is used as an extractant HFC134a. It is well-tested and highly effective solvent for extracting oils from a wide variety of biomass, having proven the applicability FDA. Under low pressure (4-6 atm) it takes a liquid form and is very easy to evaporate, turning into a gaseous state. Solvent losses during the process is very small. The process repeats until the expiration of an extraction cycle of a predetermined time, and then all the gas is returned to the solvent storage tank. Once all of the gas removed from the evaporator, the evaporator can open and remove the extract. The system is cleaned and prepared for the next cycle of the extraction. Operator involvement is minimal, the work process needs to be monitored, but the setting can be left unattended on the process. After the one-time parameter setting process provides complete their recurrence, with the only variable that depends on the quality of the biomass. HFC134a can be considered the most inert chemical, the main disadvantage is the long pot life: in nature it destroys only certain marine organisms.
