How would I go about constructing a miniature version of “The Green Grease Machine”?
There are descriptions on this website of how we built the Green Grease Machine and tips for building a processor are given in the current edition of From the Fryer to the Fuel Tank. Many of the links on World of Biodiesel Page give good examples. These sources should give you a pretty good idea of how to design a big container that mixes. A biodiesel processing station needs to be a large, high-speed mixer. Your objective is to get molecules to collide with one another and react. You have one hour to do this. The second edition of From the Fryer to the Fuel Tank, available in June 1999, will have detailed instructions, diagrams, and photos on this subject.
