Title:
APPARATUS AND METHOD FOR SIMULTANEOUSLY GRINDING CELLULOSE-BASED BIOMASS AND MIXING-IN ENZYMES
Document Type and Number:
WIPO Patent Application WO/2017/047829
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for simultaneously grinding and saccharifying biomass and a method using same, the apparatus comprising: (a) a hopper for supplying biomass; (b) a lateral extruder having the form of a cylindrical housing inside of which a rotatable screw is installed, wherein one side of the housing is coupled to the hopper, and an outlet provided on the other side of the housing is joined to an inlet for introducing biomass to a refiner; and (c) the refiner comprising a stator disc having a cooling water holding space on the outer circumferential side of the disc, at least one enzyme supplying hole arranged in a grinding area close to the circumference, and a biomass supplying hole provided at the center, and a refining disc which forms a gap with the inner circumferential side of the stator disc, is joined to face the grinding area, and is rotated by an individual motor.
