Abstract: This is a computer controlled and automated mobile and/or static process to reclaim used waste fryer oil used for cooking and convert it into biodiesel. The waste, which can contain many contaminants including food particles, and water and emulsified or congealed grease, is forcibly vacuumed into a container and heated. Contaminates are removed by passing the heated fluid via a strainer. Once determined clean by the computer, the fluid travels out of the vessel through the strainer and back into the vessel. Any water settles to the bottom of the heated chamber. As the computer senses the presence of water, it is removed via a drain. The grease is then pumped to a second chamber and treated with a titrated amount of catalyst, as determined by sensors and software. After reaction takes place, glycerin levels are monitored and removed via a strainer, and the fluid is pumped to the next chamber. pH is measured by the computer and balanced. It is processed in a final wash to remove any remaining impurities.
