[Function and effect]

  The water-absorbing treatment material 1 contains coffee beans, instant coffee or plant leaf pulverized material 20. These materials have a deodorizing / deodorizing action and a dyeing action. Therefore, the water-absorbing treatment material 1 can be provided with two effects of deodorizing effect and excellent aesthetic appearance without using a plurality of materials. Thereby, the water absorption processing material 1 which has a deodorizing effect and the outstanding beauty | look was implement | achieved, suppressing the raise of manufacturing cost.

  When coffee beans or instant coffee are used, these have a strong deodorizing / deodorizing action, and therefore a particularly high deodorizing effect can be obtained. Furthermore, since the scent of coffee has the effect of relaxing people, not only the deodorizing effect but also the aroma effect can be obtained. In addition, since coffee components are gentle to animal skin, coffee beans or instant coffee is suitable as a material for excrement disposal materials for pet animals.

  Patent Document 1 describes the use of an extracted residue of roasted coffee beans as a material having a deodorizing action. However, there is a problem that the extraction residue of coffee beans is a highly anaerobic waste and is easily rotted, so that it is difficult to handle. On the other hand, coffee beans and instant coffee are stable solids and are not easily perished, and therefore are easy to handle.

  The particle size of the pulverized product 20 is preferably less than 1 mm. In this case, the deodorizing / deodorizing action and dyeing action of coffee beans, instant coffee or plant leaves can be efficiently extracted.

  The content of the pulverized material 20 in the absorbent layer 10 is preferably 1% by weight or more and 5% by weight or less. In this case, the water-absorbing treatment material 1 can be reasonably colored by the dyeing action of coffee beans, instant coffee or plant leaves.

The pulverized product 20 is contained only in the covering layer portion 14 of the granular core portion 12 and the covering layer portion 14. In this case, compared with the case where the pulverized product 20 is contained in both the granular core portion 12 and the coating layer portion 14, the amount of the pulverized product 20 used can be reduced, thereby reducing the manufacturing cost. In addition, the action of the pulverized product 20 can be efficiently extracted when the pulverized product 20 is contained in the coating layer portion 14 present on the outer side, compared with the case where the pulverized product 20 is contained in the granular core portion 12. Therefore, when it is considered that the same amount of the pulverized material 20 is contained, the water-absorbing treatment material 1 is more likely to be contained only in the coating layer portion 14 than in the case where it is contained only in the granular core portion 12. Deodorizing effect and aesthetics can be enhanced.
[Production method]

  An example of the manufacturing method of the water absorption processing material 1 is demonstrated. This manufacturing method includes a granulation step, a covering step, a sizing step, and a drying step.

  The granulation step is a step of forming the granular core portion 12. In this step, the core material is pulverized to a predetermined size by a crusher, and the pulverized core material is put into a mixer at a predetermined ratio and mixed. And after adding water, the said core part material is extrusion-granulated with a granulator, and the granular core part 12 is formed.

  The covering step is a step of forming the covering layer portion 14 so as to cover the granular core portion 12. In this step, the coating material is sprayed or sprayed around the granular core 12 using a coating apparatus or the like. The covering material is mixed with coffee beans, instant coffee or plant leaf grinds 20. Thereby, the coating layer part 14 is formed.

  The sizing step is a step of sizing so that the dimensions of the water-absorbing treatment material become a predetermined standard. In this step, only the water-absorbing treatment material satisfying the predetermined standard is extracted by passing the water-absorbing treatment material produced in the previous step through a sieve having a sieve with a predetermined size.

The drying step is a step of drying the water-absorbing treatment material extracted in the previous step with a dryer. If the water content of the granular core 12 is too high, it will cause mold and the like during storage of the water-absorbing treatment material 1. Therefore, in this step, it is preferable to dry the water-absorbing treatment material 1 so that the water content is in the range of 3 wt% to 12 wt%.
