Apparatus for the continuous production of ethanol from cereals

摘要

The abstract is used to process cereals to obtain ethanol. In the apparatus, a limpid phase of a slurry with water and hydrolyzed starch is supplied to a saccharification stage and an output of the saccharification stage is supplied to a fermentation stage to obtain a fermentation product and a wine from the fermentation product is supplied to a distillation stage to obtain ethanol. A stationary screen with a mesh of between 150 and 300 microns is positioned in the apparatus for receiving at an input of the screen, the slurry with water and hydrolyzed starch. The stationary screen has a turbid overscreen outlet and a limpid outlet containing a limpid solution having particles up to 150-300 microns. The limpid outlet is coupled to the saccharification stage so as to supply the limpid solution to the saccharification stage. A vacuum band filter has an inlet coupled to the turbid overscreen outlet from the stationary screen. The vacuum band filter has a turbid filter outlet which is coupled back to the input to the stationary screen and has an outlet for a filtration panel. A mechanical squeezing filter is coupled to the filtration panel outlet from the vacuum band filter, has a turbid filter outlet that is coupled to the inlet of stationary screen and has a dehydrated panel outlet.
