A method of producing cellulose liquefaction and a cellulose liquefaction module that mixes and circulates cellulose material as a solid, and provides evaporative cooling in the module. The module includes a container having a vertically disposed tube that houses an auger conveyor that mixes and circulates solid cellulose material. Steam ports and activation agent injection ports are disposed within the tube to liquify the cellulose material. A forced air blower pushes air through the liquified cellulose material to provide evaporative cooling before discharge from the container.
