Description
Technical Field
The invention relates to the technical field of cat litter processing, and particularly relates to a production process for preparing cat litter by using pectin extraction residues.
Background
In recent years, pets have come into the eyes of people, and more people prefer to raise small pets, and because cat raising is labor-saving compared to other animals, cat raising is a preference of most people. The cat most needs to be fed by people to help the cat to carry excrement, and the two links are easy to solve the problem of cat raising. On one hand, the cat litter is a tired alive animal, and on the other hand, the cat urine cannot be caked and is difficult to remove due to the poor water absorption performance of the traditional cat litter; on the other hand, the traditional cat litter is too loose, so that broken cat litter particles are brought out when the cat comes out of the cat litter box, the floor also needs to be cleaned, and the workload in the aspect of sanitation is greatly increased; in addition, the traditional cat litter has poor odor absorption capacity, a double-layer mask is required to be worn when the litter is shoveled, and sometimes the odor of the cat litter is even emitted out of the cat litter box. From the above, the traditional cat litter has the problems of poor looseness, water absorption capacity, poor odor absorption capacity and the like.
China is a large fruit industry production country, and many fruit processing enterprises exist, so that fruit residues are abandoned as waste materials in many enterprises. The pectin is extracted only once after the pectin is extracted from the pomace by the existing enterprises, and the pectin is not extracted. The residual residues are directly treated as waste products, which causes resource waste and environmental pollution. The residue obtained by extracting pectin contains pectin components, so that the cat litter has an excellent water absorption effect, can effectively reduce peculiar smell, and is matched with the requirements of cat litter, so that the cat litter prepared from the pectin residue has a good application prospect.
