Brief description of alcohol production
Raw molasses is stored in storage tanks and chemicals are stored in chemical warehouses. Auxiliary materials are mixed with water in the
solution tanks and the resulting solution B is pumped to the fermentation section. Raw molasses is also diluted in a solution tank and pumped to the fermentation section.
Of course, from the second steering wheel onwards, the raw molasses is pumped directly into the steering wheels without dilution. The fermentation begins by dissolving a certain weight of dry yeast in a special tank and then transferring it to the preformer. The fermentation process is such that the contents of the pre-command are pumped to the first command and the contents of this command are pumped to the second command and so on to the fifth command. At the end of the fermentation phase, the contents of the fifth fermenter are pumped to the alcohol storage tank. This tank is just before the distillation process and is to ensure the feeding of the distillation section so that the distillation process is done continuously.
The concentration of alcohol gradually increases during successive stages of fermentation and eventually reaches about 10-9%. The air required for fermentation is also supplied through two blowers. In the distillation section, there are six tray columns that perform the process of separating ethanol from other compounds produced during fermentation.
In this section, three types of products are produced, including medical alcohol, industrial alcohol and alcohol oil, which are stored in separate tanks. Also, large quantities of CO2 gas are produced, which can be marketed as CO2 gas capsules or dry refrigerators. In general, about 3.5 kilograms of alcohol molasses is produced per liter of alcohol.
