  • Process and apparatus for producing starch-containing feedstock hydrolysates for alcoholic fermentation
    Patent number: 4302543
    Abstract: A process for producing hydrolyzates of a starch-containing feedstock for an alcoholic fermentation which comprises extrusion of a preliminary disintegrated feedstock at a temperature of 150.degree.-300.degree. C. under a pressure of 2.10.sup.5 -2.10.sup.8 Pa, followed by fermentative hydrolysis of the extrudate. The extrudate is mixed with an aqueous enzymatic solution and hydrolyzed for 30-60 minutes by creating direction vortical streams by means of a source thereof at a rotation speed of 1,000-6,000 r.p.m. with simultaneous change of their direction.An apparatus for the process according to this invention comprises, mounted downstream; a receiving bin, a lifting mechanism, balance, feeder, separator for separation of foreign matter, disintegrator, extruder and means for fermentative hydrolysis. This means is in the form of a cylindrical vessel with a cover.
