I moved to working the new extraction lab my boss wants instead of running around in the field. I havnt been there since they started harvesting. I finished my first two batches of about a quart each, of 70% canibinoid whole flower hemp extract. Franklin and Remission varieties. It takes a minute to learn some of this stuff, none of us have done ethanol extraction before, and every step of the way we need another piece of equipment, or a chiller breaks down, etc. It's been a really long couple months, but I love my job. Have had to repair vacuum pumps and broken glass bits several times along the way.
Running a -60C ethanol extraction and filtration. Our bags can hold about 8 pounds of hemp at a time, into 8 gallons ethanol, and we are manually filtering to 1 micron. Then into a 50 liter rotary evaporator, getting about 8 to ten liters per hour of alcohol out. Then warming plate to rough purge, and a vaccum oven for a final purge and decarb.
We have a centrifuge now, but it's not set up and programmed yet. There is no manual in English of course. That will replace the extraction and filtration part we are doing the hard way right now.
