In order to complete the reaction process of biodiesel production, NCEE constructed a batch blade stirrer biodiesel reactor type by applying a static mixer-reactor that is able to increase the rate of reaction of oil and methanol, in which the stirring is intensively done by the circulation pump, static mixer, and sprayer.

The functional components of the biodiesel reactors are: a tank reactor, a circulating pump, a heating element, a static mixer, and a sprayer.
