Hi everyone!
I make RSO from hemp and use 10 pounds of bud with 10 and half gallons of 195 proof ethanol. I reclaim using a 10gal copper still, using a rice cooker to quickly cook of the rest of the wash.(I reclaim 8 1/2 gallons back and am left with a half gallon of thick wash. I want to try getting 9gal back but not sure at what point it will thicken too much and that would be a nightmare to clean.) I purge and decarb using an induction hot plate in an oil bath.
My question is this: Why does sludge form? For instance, I left a batch too long in the rice cooker one time and it burnt. Why does this happen? IF the rice cooker can't exceed the 180F mark that ethanol burns at and when it switched to it's warm setting, which is lower than what is needed for decarb, why did it produce the burnt sludge?
Also, my last batch I babysat the rice cooker and that was fine. When I put it in the oil bath, which I decarb at 245-250F, it still had some sludge. Do I just need to be stirring it or get an automatic stirrer? Is it chlorophyl that is burning first and settling at the bottom? Is the bottom of my glass container that holds the RSO during decarb have the most surface area and if left still too long burns it? Would love for someone to get real nerdy here. Thank you all so much!
