OK, I'll go first. Compared to some of the regulars here, my set up is probably the most primitive, but it works well for me. I water wash. My 55 gallon drum processor is also where I spray dry my bio after washing.
Here's the setup with heated standpipe wash tank to the left, processor in the middle, and pneumatic drill powered keg methoxide mixer to the right. Both wash tank and processor have 220v heating elements wired 110V thermostat controlled.
Here's the simple processor plumbing. This is fed into a cheap HF blue pump which has, surprisingly, held up well processing and drying just over 1500 gallons of bio. I am currently constructing a new processor which will have a Pedrollo pump. Better quality and much safer.
