Description

Technical Field

[0001] The invention relates to the technical field of pet products, in particular to a pet feed and application thereof in reducing feces odor. Background Art

[0002] With the increase in the density of pet breeding in modern households and the intensive development of urban living environments, the odor problem caused by pet excrement has gradually become a key pain point affecting the experience of human-pet cohabitation. The complex mixed gases such as volatile sulfur compounds (such as hydrogen sulfide, methyl mercaptan), nitrogen-containing metabolites (such as ammonia, indoles) and short-chain fatty acids in pet feces not only aggravate the air pollution in closed spaces, but may also become a potential source of health risks. Traditional deodorization solutions mostly focus on end-of-pipe treatment, such as chemical deodorant spraying or physical adsorption methods. Such methods can only temporarily cover up the odor, but cannot interfere with the source generation mechanism of odorous substances.

[0003] From the perspective of animal nutrition, the metabolic response of pet intestinal microecology to feed ingredients directly affects the chemical composition of feces. Problems such as toxic metabolites produced by fermentation of excessive undigested protein in the colon and pH fluctuations caused by imbalanced mineral addition ratios are the core factors that promote the accumulation of malodor precursors. Most of the existing feed formula designs have the single goal of improving palatability and nutrient digestibility, and rarely systematically incorporate "full-cycle environmental friendliness" into the product development framework.

[0004] Based on this, there is an urgent need for a class of innovative feed products, whose design logic must break through the single functional positioning of traditional nutrition supply and instead build a three-dimensional product model of "nutrition-metabolism-environment" coordinated regulation. Through the precise combination of active factors with targeted regulatory functions, while ensuring the health needs of pets, the biosynthesis pathway of odorous substances can be inhibited from the digestion and absorption stage, and the source control concept of "feeding is pollution control" can be finally realized. The feasibility of this technical path has begun to emerge in the cross-study of animal ecology and metabolomics. The key lies in establishing a multi-component synergistic network that adapts to the microenvironment of the pet's digestive tract. Summary of the invention

[0005] The purpose of the present invention is to provide a pet feed and its application in reducing feces odor, which provides an effective means for solving the problems in the prior art.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0013] The present invention also provides a method for preparing the above pet feed, comprising the following steps:

[0014] a) Use a multi-bin one-scale dynamic batching system to complete raw material measurement;

[0015] b) Mixing the materials by a twin-shaft paddle mixer, with a mixing uniformity of ≥ 95%;

[0016] c) using a twin-rotor micro-crusher for micro-crushing;

[0017] d) The material is steam-conditioned in an extruder to achieve ripening and extrusion;

[0018] e) reducing the moisture content of the material to below 15% by a countercurrent cooler, and sieving to remove broken particles to obtain the pet feed.

[0019] Preferably, in the mixing process, grease is automatically injected through a liquid raw material adding system, and spraying is performed using a vacuum sprayer.

[0020] Preferably, the steam conditioning makes the starch gelatinization degree of the material ≥80%, and the diameter of the cooked and puffed puffed particles is 2 to 5 mm.

[0021] Preferably, the hot air temperature of the drying is controlled to be 80-100° C., and the drying time is 30-45 minutes.

[0022] Technical effects and advantages of the present invention:

[0023] The present invention significantly improves indoor air quality by inhibiting the biosynthesis of volatile malodorous substances in pet feces, reduces the hygienic pressure of cohabitation between people and pets in high-density living environments, and improves the living comfort of modern families. It reduces the odor pollution of fecal excrement to public spaces, effectively alleviates the burden of community environmental governance, and at the same time reduces the environmental dependence of owners on chemical deodorants, promoting the implementation of the concept of green pet raising. The deodorization mechanism based on intestinal microecological regulation simultaneously optimizes the digestive and metabolic efficiency of pets, reduces the accumulation of toxins caused by abnormal protein fermentation, and provides nutritional support for the long-term health of pets.

[0024] It can reduce the investment and maintenance cost of deodorization equipment in the feces treatment process, alleviate the odor control pressure of the centralized pet feces treatment system in the city, and form a sustainable pet feces management solution. It can also eliminate the psychological rejection caused by odor, enhance the willingness of owners to interact with their pets on a daily basis, and promote the social role recognition of pets as emotional companions. DETAILED DESCRIPTION

[0025] The technical solutions provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0026] Example 1

[0027] Raw material composition: chicken (27.81%), beef (16.61%), grains and their products (11.92%), chicken liver, oil seeds and their products, chicken hemoglobin powder, chicken oil, soybean oil, pet feed compound seasoning (2.76%), natural minerals (1.16%) and yucca powder (0.02%).

[0028] The additive composition includes amino acids, vitamins, mineral elements and their complexes (chelates), taurine, Bacillus coagulans (0.02%) and enzyme preparations.

[0029] The measured materials are weighed in a multi-bin-one-scale way, and are batched in the 2-08 batching scale according to the design of the feed formula. The prepared materials are sent to the 3-27 double-shaft paddle mixer for mixing, where additives and premixed feed can be added through the 3-25 hand-feeding port. The hand-feeding port is equipped with a 3-24 pulse dust collector to effectively prevent dust generated during the hand-feeding process; various feed raw materials are sent to the mixer according to the proportion of the formula and mixed in batches. If liquid raw materials need to be added, they are automatically added through the liquid raw material addition system. The batching system has an accuracy of 2 / 1000 in dynamic conditions and 1 / 1000 in static conditions. The mixing uniformity of the mixer can reach 95.1% (120s) and 95.7% (240s), and the CV value is ≤7%.

[0030] The mixed materials are lifted by 3-32 bucket elevators and enter the WH1 / WH2 micro-crushing bins respectively. They are crushed by 3-08-1 / 3-08-2 double-rotor micro-crushers and lifted to S1 puffing bins by 3-16-1 / 3-16-2 bucket elevators. The two crushers are equipped with pulse bag dust removal systems, which can effectively reduce the dust generated during the production process. The crushed materials enter the puffing bins through bucket elevators (3-16-1 / 3-16-2). The materials enter the SDETF160 aquatic puffing machine (6-09-1) through feeders (6-09-2). After steam conditioning, the materials and water can be evenly mixed and fully heated by steam, which has the functions of conveying, mixing and maturation. The puffing machine is equipped with a water adding device to adjust the moisture content of the materials. At the same time, the temperature of the puffing chamber is adjusted by adding water. The materials are extruded to achieve the purpose of maturation and puffing. Due to the addition of a large amount of high-temperature, high-humidity water vapor during the puffing process, and the large amount of heat generated by the material during the puffing process, the temperature and moisture content of the material puffed by the puffing machine are high. Such feed is very easy to break, affecting production efficiency and not conducive to subsequent processes; the feed particles are evenly dried by the dryer to reduce the moisture content to below 12%, and then enter the buffer bin after passing through a low-speed bucket elevator and a flat rotary grading screen. During the drying and hoisting process of the puffed feed particles, a certain amount of powdered feed will be produced. These powdered materials will be screened out through a flat rotary grading screen to ensure that neat and qualified puffed feed particles enter the buffer bin. The heat-sensitive additives, grease and the dried materials are sprayed with negative pressure by a vacuum sprayer, and the spraying ratio can reach 25%, and the spraying cycle is 6 minutes; after the spraying is completed, the feed particles are added with seasonings during the continuous mixing process, and then mixed evenly and released from the spray mixer, cooled by a countercurrent cooler, so that the heat and moisture generated during the vacuum spraying process are dispersed, and the cooled feed particles enter the finished product bin.
