The invention belongs to the technical field of a process for a cat
litter, and specifically relates to a fragrant sterilizing-type pea-
hull composite cat
litter and a preparation method thereof. According to the invention, pea hulls are capable of emitting slightly sweet and fragrant smells in the process of
processing, so the prepared cat
litter by the invention has pea-
hull fragrance,
low density and good water absorptivity, bulkiness, antibacterial properties and adsorption properties, is biodegradable, green and
environmentally friendly, and effectively improves the
living environment of a cat; meanwhile, regularly-cleaned cat litter is poured into soil and can play the role of improving soil, and the regularly-cleaned cat litter contains animal
manure, thereby being able to be used as an
organic fertilizer, so resources are saved. The preparation method provided by the invention has the following advantages: through mutual compounding effects of the pea hulls with filled-type wood, an
antibacterial agent,
sodium bicarbonate and a binder, and by adopting a vertical-type ring die granulating
machine, the prepared cat litter has uniform particle size, small pore size and good bulkiness; strong adsorption of the cat litter to
manure odor is guaranteed; meanwhile, the yield is large; and production efficiency is improved.
