Mixing Eductors for Biodiesel

Mixing Eductors for Biodiesel

The HF or NT pumps make good mixing pumps up to about 20 gallons. After that the lack of "inside the tank" mixing starts to effect quality. The solution as it turns out has been around for a long time in the chemical industry. Mixing eductors let us use small pumps to do big mixing jobs.

Beta Testing a Mixing Eductor

Beta Testing a Mixing Eductor

We used this mixing eductor in a test with 12 people to see how well it would work in an Appleseed Processor. We found an inexpensive mixing eductr that we could fit through the upper element hole with a little work. Find out how it performed in this article.

Using a Venturi to Inject Methoxide

Using a Venturi to Inject Methoxide

One issue I have with the Appleseed biodiesel processor is that you have to add the methoxide slowly or quality will suffer. With the classic Appleseed we have to tweek ball valves to get an acceptable injection rate. The venturi ends all that by giving us consistant injection rates without any adjustment.

Installing a Venturi

Installing a Venturi

In this article we upgrade a typical appleseed to include all steel plumbing, well mostly steel, and a venturi for methoxide injection. Now when we add the methoxide we just open the valve to the venturi and close the bypass valve and it sucks in the methoxide at just the right rate.

Testing A Processor for Mixing Ability

Testing A Processor for Mixing Ability

Do you need to improve the mixing in your processor? Would it be a waste of time to add a mixing eductor or would adding one let you use less methanol? This simple test takes the guesswork out of it.

Cone Bottom Inductor Tanks

Cone Bottom Inductor Tanks

Cone Bottom tanks are popular among some biodiesel enthusiasts. This is mostly due to the fact that so many commercially sold biodiesel processors have been made from them. Fuelmeister was the company that popularized this style of processor made using two inductor or cone bottom tanks.

Upgrading the Clearwater Pump fo Biodiesel Processors

Upgrading the Clearwater Pump for Biodiesel Processors

There are two pumps that are commonly used as biodiesel processor pumps. The NT Clear Water Pump has a long history of reliability when used as a biodiesel mixing pump. The less expensive Harbor Freight pump is considerably less reliable. For better or worse, homebrewing seems to be wedded to these pumps.

Vented Cubie Caps

Vented Cubie Caps

Draining the glycerin can expose you to high levels of methanol fumes. These can be virtually eliminated with a vented oil cubie cap. The cap will let you drain your glycerin into the cubies the oil came in without exposing you to methanol vapors.

Fuel Filter Gauge

Fuel Filter Gauge

Since Biodiesel is such a good solvent, any trash that gets in the tank will eventually end up in the fuel filter. It can be from old gunk from petrol diesel usage, or from when we buy diesel at the pump for winter blending. If it catches us off guard, we can end up changing out a fuel filter on the side of the highway, in the snow.

Use a Drum Desiccant Vent to keep water out of biodiesel drum

Drum Vent Desiccant

Biodiesel will absorb some water from the air over time. If you live in a humid area, water will encroach into your fuel dispensing drum and spoil all that hard work you put into getting it super dry. However if you put a desiccant vent on your drum, you can actually make your biodiesel even drier.

Water Blocking Biodiesel Filter

Water Blocking Filters

Water blocking fuel filters are both popular among homebrewers and commonly misused. They are typically 10 micron spin on filters like this goldenrod waterblock filter and are capable of capturing free and emulsified water, but not dissolved water.
