Like collection equipment, it is possible to go very slick with the machinery of filtration, centrifuging, flash evaporation and such. Most WVO folks will tell you that heat and time are your friend. With both of these you can defeat the twin foes of WVO as Fuel: Particulate matter and water. Centrifuging and fancy piping and filters will save you time. If i had lots of oil coming in and heavy use in my immediate future (a good problem to have) I would consider jumping right into a centrifuge set up.
My plan involves metal barrels with band heaters, hoses and filters. The image above is more of a logical construction than the physical plan. For instance Mist washing and de-watering, as they both require heating the oil, are likely to happen in the same barrel. Also the filters in the diagram suggest house filter casings with plumbing, it may be the case that I use sock filters and my collection pump to move the oil around. The pre-filtration unit may be a 5 gallon bucket with window screen and old sheets or a 55 gallon drum top filter. The idea at this stage is to understand what steps need to be taken to take fryer fresh oil and prepare it for the fuel tank.
