Paper recycling device and paper recycling method

Abstract

A paper recycling device includes a dry type defibrator unit, a first transport unit, a classifier unit, and a paper forming unit. The first transport unit is configured to transport using air flow the defibrated material after being defibrated by the dry type defibrator unit. The classifier unit is configured classify by an air flow the defibrated material after being transported by the first transport unit. The paper forming unit is configured to form second paper with the defibrated material after being classified by the classifier unit. The first transport unit includes a transport pipe configured to move the defibrated material, with a cross section surface area of a portion of the transport pipe on a side closer to the classifier unit being smaller than a cross section surface area of a portion of the transport pipe on a side closer to the dry type defibrator.
