ABSTRACT OF THE DISCLOSURE Continuous hydrolysis to produce sugars is effected by cyclically immersing a solid, divided lignocellulosic material in a bath of concentrated hydrochloric acid and draining the material between successive immersions so as to dissolve the produced sugars, until the sugar concentration of the acid in the bath has attained a desired value. The solid material and the liquid acid are delivered to a tubular horizontal rotary reactor arranged to provide a bath of the acid, to produce a rotating movement for cyclical im- mersion of the solid material in the bath of acid and longi- tudinally displace the solid material undergoing hydrolysis together with the acid of the bath and to continuously dis- charge solid residue and acid containing dissolved sugars due to overflow by gravity at an outlet end of the reactor.
