Before one wants to know how to make biodiesel one must know what it is actually. In layman’s words; Biodiesel refers to a non-petroleum-based diesel fuel consisting of short chain alkyl (methyl or ethyl) esters, made by transesterification of vegetable oil or animal fat, which can be used in unmodified diesel-engine vehicles.
One can divide the production of biodiesel into three simple and basic steps -
Ilseed Crushing (Basic Process)
An oil mill is designed to efficiently, mechanically extract by full pressing the oil from canola. The efficiency and performance of oil extraction with screw presses is highly dependent on the condition of the raw material.
Crude Oil Degumming/Neutralizing (Basic Process)
Crude oil obtained from the canola seed pressing operation contains a number of impurities that have to be removed before the transesterification (biodiesel) process. The impurities are moisture, gums, free fatty-acids and soaps.
