Just having my new BD processor built... GL Eco, with 4 tanks all with conical bottoms, heating elements ball valves pumps etc.
First tank sits above another tank, raw veg oil gets sucked into the top tank, heats and drops out into the bottom tank (which has a 200 micron drum strainer in it). Tank below heats oil to dewater.
Next is the main processor for glyc washing, reacting, glycerin separation (inc. centrifuging) and demething. Final tank water washes, dries via a spray bar, pass through a corny keg packed tight with hardwood shavings and final centrifuging. Then dispense via polishing / drying pots to get water <80 ppms
I should be able to process 350 litres in 5 - 6 hours which means one saturday every two months
Total cost under £1K mostly funded by the sale of my old Goldenray 120 machine, bit of a result?
