Abstract
A process for the manufacture of paper pulp containing particles for the treatment of excrement of primarily domestic animals and pets. Hot water and a filler are added to a paper pulp in solidified condition and they are agitated so as to form a slurry of the paper pulp. The slurry is subjected to a first dehydration and lumps of the pulp are produced which are subsequently cut into a plurality of smaller lumps. The smaller lumps are then rolled and become coarse particles which are dehydrated once again. The dehydrated particles are rotated and finally dried. The resultant particles are of high density and absorb water. The particles are also water-soluble so that, after use, they can be flushed down a toilet.
Claims3
A process for the manufacture of paper pulp containing particles for the treatment of excrement, which comprises:
- (a) adding hot water and a filler to a paper pulp in a solidified condition;
- (b) stirring to form a slurry of the paper pulp;
- (c) applying a first dehydration to the paper pulp slurry so that the paper pulp solids content becomes 15 to 20% by weight, thereby forming lumps of paper pulp;
- (d) forming said paper pulp lumps into a plurality of smaller lumps;
- (e) rolling the smaller lumps to and fro repeatedly so that the respective smaller lumps form coarse particles;
- (f) applying a second dehydration to the coarse particles so that their solids content becomes 28 to 45% by weight of the particle;
- (g) rotating the dehydrated particles;
- and
- (h) drying the particles so that the solids content becomes more than 90% by weight of the particle.
