Higher output regarding alcohol with reduced cost is usually desired for ethanol manufacturers. In medium-temperature cooking process connected with ethanol production, use about dual enzymes ethanol production method with Boli brand Thermostable Alpha-Amylase for liquefaction and Glucoamylase for saccarification can realize this desirable result. How does this happen? Let us take a peek into the process in depth. Before we will start, we should instead get the following materials ready: Corn or Cassava, Thermostable Alpha-Amylase Boli HA-320 belong to enzyme ethanol fermentation ( red liquid, enzyme activity 40,000 U/ml), Glucoamylase Boli GA-130 ( light to brown lightly liquid, enzyme activity 150,000 U/ml), high-temperature resistant not to mention highly-active dry yeast. When these materials are obtainable, doing this starts from selecting concerning corns and additionally getting rid associated with those unwanted foreign materials. After selection, the corn is processed in a hammer mill which grinds it into flour, or powder that exposes the cornstarch, and then sieved into qualified corn powders we may make easy use in phase 2:enzymes ethanol fuel. The mixing process develops in a slurry tank. The corn powders might be weighed prior to being transferred into tank because this determines the right volume connected with water to be added. Centrifuged liquid associated with distiller??s grain should really be added into this tank at 30% ~ 40% recycling rate, meanwhile 30% Ammonia or NaOH solution should be included all at once. This is for the purpose for keeping the pH value at 5.6 ~ 6.2 inside the liquefaction tank. Then enzymes ethanol yield must be added at the dosage level concerning 0.42 ~ 0.80 kg to liquefy 1 MT corn material. Just when was mixing is ready, we can easily set out to the next step: liquefaction.
