Assembling the drum

1. Cut half of the top of the steel drum. Better if you can find a drum which does not have the top anymore.
2. Prepare a hole for pipe attachment at the bottom of the drum. Do this by drilling a one and a half inch hole
3. Weld the pipe into the hole that you just drilled
4. Attach a brass ball valve which will serve as the drain control. Brass ball are more durable and are recommended for home made biodiesel processors.
5. Fit the heater element onto a hole that you’ll drill on the side of the drum. Heater elements can be purchased from your local hardware or be recycled from your old water heater
6. Wire the heater element properly

Chemical Mixer

1. Fasten one pulley to the mixer
2. Assemble the other pulley to the spindle of the motor
3. Weld the propellers to the end of the steel rod
4. Attach the mixer to the hinge so you can move it whenever required
5. Weld the mixer assembly on the top of the drum using angled iron as support
6. Attach one side of the hinge to the angle iron to set the mixer in the middle of the drum
7. Tightly fit the belt to the pulleys by placing a block of wood into the hinge. The mixing capability is essential to Biodiesel processor to obtain good quality fuel.
8. Attach a measuring stick made of wood to know the quantity of the Biodiesel being produced

Here are some more pointers:

Biodiesel processors are just like big blenders. The rotors will mix the raw Biodiesel.

Biodiesel containers must be leak free. Instead of welding, industrial adhesives can be used to assemble Biodiesel processors. For portability, you can attach industrial
so you’ll be able to move it from one place to another.

Remember the precautions to be observed during the production of Biodiesel. The process involves handling of hazardous chemicals before you can yield usable Biodiesel fuel.
