Abstract
A process for making singulated pulp flakes is provided. The process includes dewatering liquid pulp stock to a consistency of about 30 to about 50% solids. The process includes initial flaking to break up the dewatered pulp bundles into semi-uniform flakes having a median size of from about 3 to about 5 mmand a consistency of from about 33 to about 55% solids. The process includes drying the flaked pulp to a consistency of from about 85 to about 97% solids. The process includes flaking a second time to separate the flakes that may have bonded during drying. The product 'singulated' flakes then go to a baler for packaging. In another embodiment, the process includes blending the liquid pulp stock with at least one adjuvant prior to dewatering.
