Here are some photos of my set up for those interested. The centrifuge is from simple centrifuge, and the rest is my design.
Inside the overhead tank is about 14 feet of 5 inch square tubing, acting as a heat exchanger for the LP heat head, taken from an overhead tubular heating system. On the shelf below is a 15 gallon water heater that is gravity fed. After the water heater is a goldenrod stainless mesh filter. Followed by a pressure regulator and a 220 volt parker valve. The rotor is from Simple Centrifuge and the basin was fabricated by a local machine shop per Simple Centrifuge design
The system runs all on 220 volt and is very economical to operate. When heating the overhead to 160* I estimate one gallon of LP used and the water heater and centrifuge probably costs less than $3/day to operate. 8 gph and it takes about 48 hrs total to process 300 gallons including the initial 160* preheat and overnight settle time.
A large part of the sediment remains in the overhead tank after the preheat to 160* and is drained off after heating via a 2" gate valve in the bottom of the tank. The waterheater also collects some water that is drained off easily thru the bottom valve. The centrifuge really does a great job polishing the oil. I also added a small circulation pump in the back of the overhead to assist in the heating process taking cold oil from th bottom and putting on top. It works well to defeat the thermocline I have observed in heating large quanities.
I am very happy with the machine and it has eliminated a tremendous amount of work. I process weekly for my own oils, and as needed for those who bring feedstock to be processed on shares.
