step six: the fine fibers are dried preliminarily, and the mixed drying system (7) is used for drying the retained fine fibers preliminarily;
step seven: mixing the coarse fibers and the fine fibers, transferring the coarse fibers which are preliminarily dried in the step five into a mixing and drying system (7) to be mixed with the fine fibers together, and obtaining paper pulp;
step eight: comprehensively drying the fiber, and carrying out comprehensive drying treatment on the paper pulp in the step seven to obtain fluffy paper pulp;
step nine: transferring and collecting, namely transferring the fluffy pulp out of the device for collecting.
