The present invention includes a method and apparatus for the production of biodiesel fuel from simple triglyceride sources, such as vegetable oil. In particular, the present invention incorporates a compact processor including a vapor recovery system for removing excess alcohols from the fuel, and thus promoting ASTM compliance. The vapor recovery system includes means for conserving and storing the excess alcohol for further use in the processing of biodiesel fuel. Additionally, a chemical cleaner in the form of an adsorbent material is introduced into the fuel prior to filtering in order to remove particulate matter and other impurities in the biodiesel fuel. |
