Process for ethanol production from sweet potato.

摘要

Process for production of ethanol extrau00ecdo of sweet potato, consists of a process for extraction of ethanol alcohol (1) from the raw material of starch of sweet potato (2) and (3) due to saccharification, belonging to the field of industry troubling where the sweet potato is ground (4) And transformed into the sharps.Water is then added (5) in a proportion of twenty percent (20%) of the original volume or more, depending on the properties of the equipment agitator (6), subjecting the mixture to heat (7), and once you reach the seventy degrees Celsius (70 198 C).Add the enzyme alpha amylase (8) (trade name Termamyl 120L) in the proportion of 500ml per tonne of starch; keep the mixture or juice, heated between 90 and 95 198 C for about 120 minutes.The saccharification and fermentacu00e3o: dilute the must to get to the end of fermentation. The quantity of 10 to 11 198 GL; cooling (9) until the temperature between 28 and 34 198 C and perform the correction of pH (10) for values of 5.0 to 5.5; forward the must for a tank fermentor (11) that reaches 5 to 10% of its capacity and add the yeast inoculum and the enzyme (12) referring to its total volume.
