Abstract
The invention discloses pine agglomeration deodorizing cat litter and a preparation method thereof, wherein the raw materials comprise pine powder, volcanic ash, a binder, starch, green tea powder, soybean fiber and a natural plant sterilizing agent; placing the pine wood powder and the baked volcanic ash into a crusher to be crushed into mixed powder after being steamed and boiled in high-temperature steam; mixing binder, starch, green tea powder, soybean fiber and natural plant degerming agent, and stirring; and (5) placing the mixed material in a granulator for mixing granulation and molding. The pine-wood-conglomerated deodorizing cat litter prepared by the invention can be conglomerated after being used, the use amount of the cat litter is saved, the cat owner can conveniently clean the cat litter, and the technical problem that the cat and a consumer are uncomfortable due to the fact that the pine of the traditional pine-wood cat litter is thick in taste is solved.
Description
Technical Field
The invention relates to the technical field of pet padding cat litter, and particularly relates to pine conglomeration deodorization cat litter and a preparation method thereof.
Background
The cat litter is used for burying objects of excrement and urine for the cat raised by a feeder, has better water absorption, can be generally used together with a cat litter basin (or called a cat toilet), and can be poured into the cat litter basin by a proper amount of cat litter so that the trained cat can walk into the cat litter basin to be convenient for the cat litter to go up when needing to be excreted. The cat litter is divided into two categories according to the use characteristics, namely caking cat litter and non-caking cat litter. The conglomerate cat litter is formed by the cat litter after absorbing urine and excrement, and is convenient to clean by matching with a cat litter shovel; the non-caking cat litter is characterized in that the cat litter cannot be caked after meeting urine and excrement, is inconvenient to clean after being used, and has larger dosage than the caking cat litter. Accordingly, the agglomerated litter is more desirable to consumers than non-agglomerated litter.
The bentonite cat litter is a representative of the agglomerated cat litter, the main component of the bentonite cat litter is bentonite, and the bentonite cat litter can be agglomerated after being contacted with urine or excrement, however, the bentonite cat litter has strong water absorption and is easily influenced by the surrounding environment such as weather humidity, and the like, so that excessive non-usability loss is generated; moreover, the bentonite cat litter has large dust, and the kites can frequently sneeze after long-term use; although the bentonite cat litter has good caking property, the bentonite cat litter cannot be degraded and is unfavorable for the environment after being used; in addition, bentonite cat litter has a poor deodorizing effect.
Pine cat litter is a cat litter product made from recycled pine, paper pulp, or wheat by-products. The cat litter is prepared by using pine sawdust as a main raw material and a small amount of adhesive for granulation, and has small dust and better water absorption. The pine cat litter can be thrown away in batches after directly absorbing urine, however, the pine cat litter generally belongs to non-caking cat litter, becomes powder after absorbing urine, is inconvenient to clean, and therefore needs to be thrown away completely after being used for a period of time, so that the using amount of the cat litter is increased, meanwhile, the cat litter has a strong pine smell, and people or animals who do not like pine or wood dust smell are sensitive to the cat litter, and even have uncomfortable feelings such as headache.
Disclosure of Invention
In order to solve the problems, the invention provides pine conglomeration deodorizing cat litter and a preparation method thereof.
According to one technical scheme, the pine conglomerate deodorizing cat litter comprises, by mass, 35-40 parts of pine wood powder, 15-25 parts of volcanic ash, 10-16 parts of binder, 15-25 parts of starch, 3-10 parts of green tea powder, 10-25 parts of soybean fiber and 2-8 parts of natural plant bactericide.
Preferably, the natural plant antibacterial agent is one or more of quassia, tea bran powder or horseradish.
Preferably, the starch is modified corn starch, and the specific modification method is as follows:
(1) adding corn starch into deionized water at room temperature, and stirring to obtain starch milk;
(2) heating the prepared starch milk to 50-55 ℃, and adjusting the pH to 9-10;
(3) and dropwise adding sodium hypochlorite into the starch milk with the adjusted pH value to perform oxidation reaction, reacting for 1-1.5 hours, adding sodium metabisulfite to stop the reaction, cooling to room temperature, adjusting the pH value to 6-6.5 to obtain oxidized starch milk, and performing spray drying to obtain the modified corn starch.
Corn starch is often used as a binder in the preparation process of cat litter, however, starch often has the technical problems of low binding strength and poor water resistance, and the starch can not only enhance the binding force with paper fibers, but also reduce the retrogradation tendency of amylose to the minimum by adding sodium hypochlorite serving as an oxidant to oxidize hydroxyl groups in the starch molecules into carboxyl groups under the weak alkaline condition, thereby keeping the stability of viscosity, so that the prepared cat litter can rapidly absorb water and bind together when meeting urine.
Preferably, the binder is one or more of attapulgite, bentonite, sodium hydroxide, magnesium oxide, guar gum, xanthan gum, carboxymethyl cellulose, pectin, polyacrylamide, sodium alginate, hydroxypropyl starch, propylene glycol alginate, beta-cyclodextrin and sodium starch phosphate.
Preferably, the cat litter structure is a shell-core structure, the core raw materials comprise pine wood powder, volcanic ash and a binder in parts by mass, and the shell raw materials comprise starch, green tea powder, soybean fibers, a natural plant degerming agent and a binder.
