Patent number: 7628828Abstract: An integrated biodiesel processor is disclosed. The integrated biodiesel processor includes a main reaction tank for storing feedstock to be processed and within which the reactions take place to form a biodiesel product from the feedstock. The integrated biodiesel processor also includes one or more secondary tanks integrated with and disposed within the main reaction tank. The secondary tanks are configured to store reactionary ingredients to be released into the main reaction tank in order to generate reactions.Type: GrantFiled: September 12, 2006Date of Patent: December 8, 2009Assignee: Springboard Biodiesel, LLCInventors: Galen M. Bowen, Daniel P. Bowen
