May 2018 testing by Infinity Supercritical to determine advantage of using ethanol cosolvent.
Equipment Configuration: Infinity Supercritical 10L Vertical Extraction, 40:1 Gearbox, TriboTube Down Tubes (for electrostatic precipitation), Flow Bar, Small Heat Exchanger, No Basket, Insulated Chiller Lines, Chiller set to 30 F, PID’s, Stock Valves, Check Valve, PID Controlling Pressure in Reservoir (set to 715 psi).
Processing Test Run Dynamics: Infinity Supercritical Cascade Hops botanical oil extraction. 454 grams of Cascade hops were put into the extraction vessel. This was a test cycle of 2.5 hours to see the result without using 10 percent ethanol as a cosolvent. The FlowBar allows penetration of the botanicals through the entire length of the extraction vessel, from the inside to the outside of the botanical. This complete infusion of the CO2 means faster extraction times and more cycles per day, which results in larger amounts of product that can be processed.
More testing needs to be done with ethanol as a cosolvent. The extract had a green hue, which means that either there was too much ethanol, or it was soaked too long in the ethanol. Ethanol has to be rotovaped to determine accurate extracted results.
