 Tanks
Photos of tank designs we've used. Some good, some bad.
Tank stack that we used for processing WVO. Dirty WVO is placed in the top tank and clean oil out flowed the centrifuge into the bottom tank. All gravity fed. Tank has an element in the bottom to heat the oil. Not shown in the picture is the water trap before the centrifuge and the timer valve that controlled the flow into the centrifuge. Tank stack that we used to process motor oils. Like the WVO stack we used a water trap and timer valve before the centrifuge. You can see the centrifuge mount between the tanks. We have switched to vertical tanks. Tank rollers used when prepping tanks for paint.

Making a five gallon bucket into a centrifuge feed tank is simple. Start by drilling a hole with a suitable hole saw. Install the bung. This is the view from the inside. This is the view from the bottom. Be certain to tighten it well so that it doesn't leak.

This is the finished bucket tank. I drilled a hole in the top of the stool so the pipe and valve could pass through. This is very easy to move around. I needed a setup in the shop to demonstrate the centrifuge. This is a photo from inside the tank while filling from the centrifuge. This is used motor oil being processed warm (inside our shop) at 5 gallons per hour, about 1/4 what Mike normally does at the farm. What is interesting about this photo is in addition to the stream of oil coming from the centrifuge you can see the oil mist that comes in also. If our seals weren't good this mist or oil vapor would escape into the air, which we breath. It would also leave a thin oil coating on everything. I've never seen vegetable oil create such a fine mist as this motor oil. This is a used oil tank we recovered after a fire. Note how the paint was burned off the top of the tank but not the bottom. The recovered oil was really nice after being heated so hot. The tank had a thick layer of crud on the bottom that fell out of the oil during the fire.
