Glucose-containing products can be manufactured in apparatus comprising a continuous screw conveyor member rotatable in a continuous press cylinder having three regions in cascade arrangement between an intake opening and an output opening. The regions comprise an intake region for the rapid and economical intake of different kinds of products, a compression region for building up a very high pressure of from about 20 to 300 bars for disintegrating the products and for heating the product by intensive shearing thereof to a temperature of up to 250°C., and a catalyst injection region for intensive action on and mixing or hydrolysis of the cellulosic substances with trifluoroacetic acid or the like injected through nozzles. Thus glucose-containing products can be hydrolyzed by the action of trifluoroacetic acid, in apparatus in which all the working steps to be carried out can be performed continuously, without having to use individual pieces of equipment such as soaking containers, boilers, refiners and corresponding connecting ducts and valves.

Apparatus for the continuous manufacture of glucose-containing products, comprising: (a) press cylinder means defining an intake region, a compression region and a catalyst injection region, (b) a material intake opening communicating with said intake region for delivering said products to said press cylinder means, (c) a valved material output opening adjacent the end of said injection region and openable when a preselected pressure in said press cylinder means is exceeded, (d) a rotary screw conveyor means mounted in said press cylinder means and extending through said intake, compression and injection regions, the construction of said screw conveyor means and said press cylinder means in said injection region being such that the cross-sectional area and thus volume of said injection region available to material containment in substantially greater than in said compression region, (e) a plurality of pins extending radially inwardly through said press cylinder means in said compression region to a position adjacent the base of the thread of said screw conveyor means, the helical flights of said screw conveyor means being radially interrupted in the regions of said pins to permit rotation of said conveyor means, whereby high pressure is built up in said compression chamber with consequent disintegration of the material, and (f) catalyst injection nozzles extending through said press cylinder means in at least said injection region for admitting catalyst to such region, the catalyst and relatively greater cross-sectional volume in the injection region further intensifying the mixture and consequent disintegration of the material in said injection region prior to discharge.
