Patent ID: 7628828

Claim:
An integrated biodiesel processor, comprising: a main reaction tank for storing materials to be processed, the main reaction tank having a reaction chamber; plumbing coupled with the main reaction tank, the plumbing being unexposed and disposed within the main reaction tank, thereby helping to reduce risk of external spillage of fluids from the plumbing and protect the plumbing from damages; a first secondary tank disposed within the main reaction tank, and configured to store a first set of reactionary ingredients to be released into the reaction chamber of the main reaction tank thereby causing an esterification reaction in the reaction chamber, the first secondary tank including a port configured to allow passage of the first set of reactionary ingredients into the reaction chamber by way of the plumbing; a second secondary tank disposed within the main reaction tank, and configured to store a second set of reactionary ingredients to be released into the reaction chamber of the main reaction tank thereby causing a transesterification reaction in the reaction chamber, the biodiesel processor configured such that both the esterification and transesterification reactions occur in the same reaction chamber to produce biodiesel in the reaction chamber, the second secondary tank including a port configured to allow passage of the second set of reactionary ingredients into the reaction chamber by way of the plumbing; wherein the biodiesel processor fits into a rectangular prism having a volume of less than 1 cubic foot per gallon of batch processing capability.
