Method for producing rumen-passing protected product for ruminants and granules of rumen-passing protected product

Abstract

The invention discloses a method for producing a rumen-passing protected product for ruminants and granules of the rumen-passing protected product, and relates to a method for producing rumen passing granules, in particular to the technical field of production of rumen passing granules for ruminants by taking a feed solution and a rumen-passing packing material as major raw materials. In the method, the feed solution is subjected to processes of spraying fluidized bed pelletizing, fluidized bed coating and unqualified product handling through a spraying fluidized bed pelletizing machine, a polishing machine, a sieving machine, a quantitative metering device, a fluidized bed coating machine and a sieving machine. The method is characterized in that rumen-passing pills are produced by the spraying fluidized bed pelletizing process, and rumen-passing coatings are produced by the adjustable fluidized bed coating process, so that the a high-content rumen-passing protected product which meets requirements is obtained. The method is particularly suitable for industrial mass production, and has the advantages of good product quality, high yield, low production cost, stability in running and safety.

Description

technical field [0001] The invention relates to a production method of rumen-passed granules, in particular to the technical field of production of rumen-passed granules for ruminants by using raw material liquid and rumen-passed packaging materials as main raw materials. Background technique [0002] Rumination refers to the special digestive process of ruminants such as cattle and sheep. The digestive physiological characteristics of ruminants are generally similar, and there may be some differences in details. The stomach of adult cattle and sheep is composed of rumen, reticulum, braided stomach, and abomasum. [0003] The digestive function of the rumen is far less than that of the abomasum. The abomasum, also known as the abomasum, accounts for 8% of the total volume of the four stomachs. Its function is the same as that of monogastric animals, and it can secrete digestive juice and digestive enzymes. The abomasum of ruminants can digest the undigested feed in the rume...

AI Technical Summary

Problems solved by technology

[0018] e. Continuous production is basically not feasible, manual operation between processes, too much interference, and many man-made pollution paths, it is impossible to make a GMP production line

[0019] f. Repeated powder drying, water mixing, granulation, drying, etc., determine its high production cost

[0020] 2. High-content, high-strength, and smooth nuclear pellets are basically impossible to produce, and the product quality is not good (low effective content), and the yield is low:

[0021] a. Due to the influence of mixing-wet granulation, after adding auxiliary materials, the content of the finished product will decrease. At this time, after the content of the finished product increases, it will not be able to coat more materials, and the protective effect of passing through the rumen will be affected

[0022] b. For example, sugar nutrients are affected by viscosity, and auxiliary materials must be added, otherwise they cannot be made into nuclear pills

[0023] c. Strong water-absorbing nutrients such as choline chloride must also be added with auxiliary materials, otherwise they cannot be made into nuclear pills

[0024] d. For example, amino acid salts are not only affected by general water solubility and viscosity, but also affected by crystallization characteristics. During wet granulation, rounding, and drying processes, crystallization will occur, that is, crystal water chestnuts appear on the surface, so the core The surface of pellets is difficult to be smooth, so wet granulation and full circle production are difficult, and pure nuclear pellets without supplementary materials cannot be produced at all.

[0025] e. Wet granulated granules are prone to microscopic cracks and unqualified granule strength during the drying process, and are easily broken during the coating process, resulting in unqualified coated products

[0026] f. When dealing with unqualified products, if you return to the wet granulation process, the content is not easy to adjust, and if you do not return the yield, the impact will be too great

[0027] 3. The existing coating method cannot be mass-produced, and the quality is difficult to guarantee:

[0028] a. At present, there is no fluidized bed coating machine on the market with a single batch processing capacity greater than 300 kg, which will be affected during large-scale production. It can handle 300 kg. As the coating process progresses, the volume of the incoming nuclear pellets will continue to increase until about 2 times. The fixed spray gun, top spray type, and bottom spray type spray gun will all lead to poor coating quality. It is difficult to pass the test. It is found through applied research that when the processing capacity is greater than 20 kg per batch and the coating weight gain reaches more than 100%, the coating quality will be unqualified;

[0029] For example: in a normal fluidized bed, during fluidization, large particles will tend to concentrate at the bottom, small particles will tend to concentrate at the top, and the spray gun with a fixed position, when the fluidization material level increases, for the increased fluidization position , the spray gun is easy to spray; the spray gun in the form of top spray, when the height of the fluidized material level changes greatly, the height of the spray gun mouth from the upper surface of the fluidized layer will change, resulting in changes in the coating quality, and more small particles are packed; common The fluidized shape of the fountain and the spray gun in the form of bottom spray, when the height of the fluidized material level changes greatly, the fluidized state of the fountain changes, the adhesion rate increases and other reasons lead to unqualified quality

[0030] b. Due to the above-mentioned reasons, the uniformity, smoothness and strength of the pure product core pellets have problems, which directly lead to the inhomogeneity of the coating

[0031] In summary, even if the above-mentioned technical method can successfully prepare nuclear pellets, it is difficult to apply to industrial mass production because the process procedure is too complicated

[0032] In 2012102562273, a spray granulation method, the inventor disclosed a process possibility of directly obtaining nuclear pellets from liquid raw materials, but it is also impossible to obtain perfectly qualified nuclear pellets. In addition, ordinary fluidized bed granulation The granules produced by the process are either not dense enough, or the roundness of the granules is not enough, or the uniformity is not enough, or the granule strength is not enough, or the surface smoothness of the granules is not enough, or it cannot be continuously mass-produced, and the nuclear pellets that meet the requirements of the rumen cannot be produced.
