METHOD AND DEVICE FOR HYDROLYSIS OF PREFERABLY SOLID ORGANIC SUBSTRATES Russian patent published in 2015 - IPC C12M1/00 B65G33/00 D21B1/36 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to field of biotechnology, in particular to equipment for hydrolysis of preferably solid organic substrates: energy crop and plant wastes. Device contains accumulating reservoir (1), transportation device (4), steam separator, made in form of cyclone, (14), expansion tank, placed before steam separator, (15), hydrolyser (10) with loading device (7). On output side hydrolyser has device (12) for pressure relief with valve-controlled pressure diaphragm (13) and steam separator (14). Transportation device (4) is made in form of transportation screw (4') with hollow shaft (25), in which hot steam from steam separator (14) is supplied. Hollow shaft (25) in zone of transportation of organic substrate in heating zone (18) has holes (26) for steam output for direct impact with hot steam on organic substrate, with valve-controlled drain port (27) or switching valve (32) being made on shaft (25) end to remove substrate, penetrating into hollow shaft (25) through hole (26) for steam output. In method of hydrolysis with application of device for hydrolysis of solid organic substrates, including thermal pressure hydrolysis, separation of hot steam by pressure relief after output of partial quantity of substrate with its further application for heating of organic substrates supplied for hydrolysis, realised is introduction (blowing-in) of separated hot steam into hollow shaft (25) of transportation screw (4') through hole (26) for steam output and for removal of substrate from hollow shaft (25), penetrating through hole (26).

EFFECT: group of inventions provides higher output of substrate with improved quality.
