Abstract

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.degree. 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.
