vacuferm is an important new process for the rapid fermentation production of alcohol fuel. Vacuum fermentation is an effective way to remove end-product inhibition and thus greatly increase ethanol productivity.Fermentation technology has a bright prospect as a method for producing ethanol. This is because of the raw material is cheap and moreover it is renewable. Ethanol fermentation can be carried in bulk / batch or continuous.
C6H12O6 à 2 C2H5OH + 2 CO2 + energy
Materials used are several chemicals such as phenolphthalein indicator, potassium phosphate, ammonium nitrate, hydrochloric acid, sucrose, fructose, and glucose, Saccharomyces cereviseae strains were obtained from the laboratory of microbiology.
The main equipment used consists of two tools for the fermentation process/fermenters and vacuum pump unit as figure. Comprises a tool consisting of stirred bioreactor with a cooling reactor, temperature and pH indicator. Bioreactor was from BIOTRON, Inc. Volume of 2000ml of fermentation media.
