Fig. 1 is a flow chart of a preparation method of the selenium-rich feed for donkeys, which is provided by the embodiment of the application. As shown in the attached drawing 1, the preparation method of the selenium-rich feed for donkey provided by the embodiment of the application comprises the following steps:
Respectively crushing corn, bean pulp and rice bran meal;
obtaining corn, bean pulp, rice bran meal and premix according to the raw material proportion of any one of claims 1-5;
mixing corn, bean pulp and rice bran meal, adding premix and mixing uniformly;
And (3) feeding the uniformly mixed corn, bean pulp, rice bran meal and premix into a compression chamber of a granulator for compression to generate granulated feed.
The corn, the bean pulp and the rice bran meal are crushed mainly to control the granularity of the materials. According to the variety to be produced, the sieve sheet of the pulverizer is replaced in time, and the hammer sheet, the sieve sheet, the current, the noise and the pulverizing path are monitored and confirmed at any time, so that the pulverized material is ensured to enter the corresponding proportioning bins; the crushing quality directly influences the yield and the power consumption of feed production, and the power consumption also influences the inherent quality and the feeding effect of the feed; the crushed particle size is different with the difference of animals, and when the crushed particle size does not meet the requirements of livestock and poultry, the digestion and absorption of the livestock and poultry after eating the feed are influenced; and when the materials which do not meet the requirement of granularity are produced, the feed quality and the production efficiency are seriously influenced. Before production, whether a sieve sheet of the crusher is damaged or not, the main direction and the abrasion condition of a toothed plate and whether a hammer sheet is incomplete or not are checked, the size of a feeding controller is adjusted according to the properties of materials to be crushed, and the like, so that abnormity is found and corrected in time.
Mixing corn, bean pulp and rice bran meal, namely, unloading various raw materials which are weighed and batched into a mixer according to a batching scale, adding grease according to needs, and setting mixing time according to the performance of equipment to ensure that all components are uniformly mixed to achieve the required mixing uniformity.
The raw materials of the mixed premix are mixed with calcium hydrophosphate, mountain flour, a carrier, salt, lysine, a phagostimulant, magnesium sulfate, multi-vitamin for donkey, multi-mineral for donkey, yeast selenium and sodium selenite according to the raw material ratio in the premix.
Further, in this embodiment of the present application, before obtaining the raw material, the method further includes: cleaning the impurities in the corn, the bean pulp and the rice bran pulp.
impurities in the feed raw materials not only affect the quality of feed products, but also directly relate to feed processing equipment and personal safety, can cause the damage of the whole equipment when serious, and affect the smooth production of the feed, so the impurities are removed in time. In the feed raw materials, the impurities of the animal protein feed, the mineral feed and the trace element medicament additive are all finished in the production of the raw materials, and generally do not need to be cleaned in a feed factory. Liquid materials (such as grease and the like) are often cleaned by arranging a filter in a discharge or feed tank pipe. The feed raw materials which need to be cleaned are mainly grain feed and byproducts processed by the grain feed, and stones, soil, bag pieces, ropes, metal impurities and the like in the grain feed are mainly cleaned. The impurities in the corn, the bean pulp and the rice bran meal are cleaned mainly by screening and magnetic separation equipment. For example, the screening equipment such as a cylindrical pre-cleaning sieve is used for mainly removing large and long impurities such as stones, mud blocks, gunny bags and the like in the raw materials, such as a grid sieve at the auxiliary material feeding port; the subsequent trommel screen removes fine impurities from the raw material. Magnetic separation equipment such as permanent magnetic drums in the crusher and the granulator mainly removes metal impurities such as raw iron.
Whether the quality is changed or not is checked during feeding, corresponding treatment measures are taken in time when the raw materials are found to be abnormal, and unqualified raw materials are strictly required to be selected in time and cannot enter the next procedure. If the corn is easily polluted by the mould to generate toxin, mould grains are removed; the inferior soybean meal with abnormal color, bad smell and mildewed and caked blocks also can not be used as a feed raw material. The raw materials are accurately conveyed to the corresponding proportioning bins after being cleaned and purified. The bottom of the bucket elevator, the scraper conveyor, the screw conveyor and the buffer section of the chute are easy to generate the residue of the old materials and cross contamination, and the parts are required to be cleaned regularly.
Further, in the preparation method of the selenium-enriched feed for donkeys provided in the embodiment of the present application, before the uniformly mixed corn, soybean meal, rice bran meal and premix are fed into a compression chamber of a granulator and pressed to form granulated feed, the method further comprises: and (3) tempering and processing the uniformly mixed corn, bean pulp, rice bran meal and premix compound at the temperature lower than 80 ℃.
the material is sent into the compression chamber of the granulator after being magnetically separated and tempered from the bin to be granulated and is pressed into granulated feed, magnetic separation equipment must be regularly cleaned to avoid iron impurities from damaging the granulator, the steam quantity, the feeding speed, the rotating speed and the like are adjusted according to the requirement of the variety of the granules during tempering, and the ring die (the aperture, the compression ratio, the material and the like) is selected according to the quality requirement of the feed variety on the granules.
The adjustment of steam quantity and feeding quantity during tempering is related to the feed quality and the production efficiency, and the residence time of tempering has influence on the quality of tempering and granulating. This process also has a significant effect on the heat sensitive nutritional ingredients vitamin a, vitamin E, vitamin B1, vitamin C and folic acid. Therefore, the temperature for modifying and molding the granules is generally not more than 80 ℃, so that the activity of the beta-glucanase can be ensured, and the digestibility and the sterilization effect of the feed can be ensured.
Further, in the preparation method of the selenium-rich feed for donkeys provided by the embodiment of the application, the method further comprises the following steps: the granulated feed is cooled by a cooler, and standard granulated feed is screened out by a screening device.
The granulated feed is cooled by a cooler, and standard granulated finished materials are screened out by screening equipment. During cooling, the material level device and the air quantity of the fan of the cooler are adjusted according to factors such as variety, indoor temperature and humidity, season and the like, so that the qualified particle temperature is reached. The particles to be crushed according to the variety requirement are crushed into proper particle size by a crusher.
according to the selenium-rich feed for donkeys and the preparation method thereof, the premix is used for improving the selenium, vitamin and mineral content of the feed. Selenium-enriched yeast and sodium selenite are added into the premix to improve the selenium content in the feed, the selenium yeast is an organic selenium source developed by utilizing yeast, inorganic selenium is added in the yeast fermentation process, the inorganic selenium is absorbed by yeast cells, and high-valence selenium is reduced into Se through a series of reduction reactions2-Finally, mainly takes part in protein synthesis in the forms of selenomethionine, selenocysteine and the like, can stimulate the activity of fiber decomposing bacteria, change the digestion of fiber and change the acetic acid and propionic acid proportion of the rumen of the ruminant, thereby realizing the regulation and control of rumen fermentation, further improving the production performance of the ruminant and increasing the selenium content in donkey milk from 0.0067mg/Kg to 0.024 mg/Kg.
