Flowable and meterable densified fiber flake
View Patent ↗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 mm 3 and 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.
1. A process for making singulated pulp flakes, comprising:
dewatering liquid pulp stock to provide a dewatered pulp;
flaking the dewatered pulp to provide wet flaked pulp;
drying the wet flaked pulp to provide dried flake pulp; and
flaking the dried flaked pulp into the singulated pulp flakes, without forming a pulp sheet.
2. The process of claim 1 , wherein the dewatered pulp has a consistency of from about 30 to about 50% solids.
3. The process of claim 1 , wherein the flaked pulp has a median size of from about 3 to about 5 mm 3 .
4. The process of claim 1 , wherein the dried flaked pulp has a consistency of from about 85 to about 97% solids.
5. The process of claim 1 , further comprising blending the liquid pulp stock with at least one adjuvant prior to dewatering.
6. The process of claim 5 , wherein the adjuvant is at least one of coupling agents, silicates, zeolites, latices, crosslinkers, debonders, surfactants, dispersants, clays, carbonates, biocides, dyes, antimicrobials, flame retardants, preservatives, synthetic fibers, glass fibers, carbon fibers, and natural fibers.
