Bringing this post back alive.
I have a Earth Systems composter and it is worth every cent. I’m making flake soil that my tityus love. Time needed is 5-7 days and a week or so resting out of the machine. For the resting period I move the soil to a trash can with vents cut into the lid. I mix it with a paint mixer and drill every day or every other day. Maximum loading of the machine produces right around 5 gallons of soil. I’ve only done single passes with the soil for now. I like it so much I recently bought a second one that will be here in a couple of days. Once the second one arrives I’ll try multiple sessions to create different degrees of breakdown. I haven’t tried leaves yet as I have a stable supply of naturally broken down leaves but I might try a batch to see how it does. I’m also thinking about making some kinshi from single pass soil to see if i can speed up that process. I use matured kinshi as white wood. No more buying flake soil that is cut with compost or soil.
Single pass soil is also working well for isopod and millipede substrate.
