Processing
Clamp a cotton sheet over drum for first stage filtering in drum 1 (larger particles) this collects part fats and chips etc, when settled the part filtered oil can be drawn off from a pipe/valve slightly higher than the base (200mm), away from the water and fats settling area (Safe zone/Crud layer). This is now placed in drum 2 for heating upto 60c (Drying), roughly takes about 3 hours to reach dependant on ambient room temperature. Once heated settle for at least 1 week, water and fats drop faster when heated and cooled/settled. After settling period pump oil through first set of filters into holding drum 3 or 4, oil is pumped through 50 and 20 micron stage filters, gradually reducing the micron at each stage, last set of filtering takes oil through 10 and 1 micron filters when pumped into your desired container for pouring into your vehicle.
