May 2018 testing by Infinity Supercritical to determine any differences by using botanical baskets, or running without baskets.
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).
Background: The use of a basket to hold botanicals, was an industry first by Infinity Supercritical. It allows fast turn-around of machine cycles, since the extraction vessel (EV) does not need to be vacuumed out. It also allows high-end flower product to be quickly stored and cyrogenically flash frozen, for use in live resin extractions. In this test, we see what the result of using the Infinity Supercritical 10L system without the basket. In this test, botanicals are placed directly into the vertical Extraction Vessel for processing. At the end of the cycle, a shop vac is used to remove the botanicals.
Processing Test Run Number 162 Dynamics: 2.5 hours Cascade Hops run. No basket. 454 grams of Cascade Hops (whole leaf). Large yield of 76 grams of extract on 454 (1 lb) of botanicals, which is about 17 percent extraction. This 2.5 hour (150 minute) continuous run is interesting to compare to our 30/30 minute run with basket, which resulted in a total extraction of 65 grams of oil, which is about 14 percent. Our next test will be to do a 30/30 run without the basket. The comparison of the 30/30 versus the 2.5 is only 3 percent. So you run the extract 1.5 hours to get out an additional 3 percent oil.
