METHOD AND DEVICE FOR MANUFACTURING SUGAR SOLUTION Russian patent published in 2015 - IPC C13K1/02 C12P19/14 

FIELD: chemistry.

SUBSTANCE: invention relates to method of manufacturing sugar solution and device for method realisation. Method comprises addition of carbohydrase to cellulose to realise primary hydrolysis, separation of solid and liquid phases of primary hydrolysate to obtain primary sugar solution, stage of adding water to solid substances, realisation of secondary hydrolysis, separation of solid and liquid phases of secondary hydrolysate to obtain sugar solution and residue, filtration of primary and secondary sugar solution through ultrafiltration membrane, with reaction time of first hydrolysis constituting from 2 to 200 hours, concentration of solid substances before secondary hydrolysis constituting from 1 wt % to 20 wt %, and reaction time of secondary hydrolysis constituting from 5 to 180 minutes. Device for realisation of method of sugar solution manufacturing contains tank with mixer for primary hydrolysis, first device for separation of solid and liquid phases of primary hydrolysate, tank of secondary hydrolysate or press-filter for secondary hydrolysis, second device for separation of solid and liquid phases of secondary hydrolysate and device with ultrafiltration membrane.

EFFECT: invention makes it possible to increase output of sugar and quantity of extracted enzyme.
