May 2018 testing by Infinity Supercritical to determine advantage of using nitrogen pressurized soak and explosive decompression as a pre-treatment.
Video of Extraction Test: Infinity Supercritical Extraction Video of Test 165
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 and pressurized to 2,000 psi for 2.5 hours as a pre-soak treatment. The vessel was then rapidly depressurized, and then the basket was put into a Infinity Supercritical 10L machine for a standard 2.5 hour run. Machine was stable and ran well with no stalls. Product was left overnight, came out very liquidy. Large, dense yield. Light color (lightest we’ve seen). All of yield in Collection Container 1 (CC1). Looks like small amount, but weighs heavy. Distilled extract (to be sure there wasn’t any ethanol from cleaning prior to run), but only last 3 g of weight, with lots of heavy liquid left.
