Description

Technical field:

[0001] The invention relates to the technical field of ruminant feed, in particular to a corn tablet medicine capsid for livestock medication and a production method thereof. Background technology:

[0002] Corn flaking is one of the commonly used feed technologies for livestock feeding. It can mature corn starch to make it soluble, greatly improving the digestion and absorption rate of livestock.

[0003] The current corn flaking process is mostly a steam-ripening and pressing process. During the process, the dry corn kernel raw materials need to be crushed and then watered to adjust to a high moisture content (20% to 30% by mass) for sufficient moistening and gelatinization. After that, steam drying is adjusted to a low moisture content (10% by mass) and then hot roller pressing is performed. During this period, heating and evaporation of water accounting for about 20% of the mass of the material are required. This process consumes a lot of energy and water. Although some energy and water can be recycled through heat recovery cycle design and water recovery cycle design, it still constitutes the main process cost of the corn flaking process. If this part of energy and water consumption can be reduced, the cost of corn flaking feed can be greatly reduced, promoting the promotion of this advanced technology.

[0004] At the same time, current related production is all based on the compression of simple corn raw materials. When feeding ruminants, due to the lack of wood fiber in corn raw materials, the stimulation to the reticulum is relatively low. Using it alone as feed can easily lead to reduced rumination, rumen food accumulation and bloating in livestock such as cattle and sheep. It usually needs to be mixed with fibrous feeds such as silage. However, the two feeds are easy to stratify due to differences in physical properties, resulting in uncontrollable feed intake ratios for individual livestock, and the above-mentioned problem of reduced rumination cannot be completely solved.

[0005] In the process of solving the above-mentioned technical problems, the inventors of this case discovered that the sheet-like composite of corn flakes and grass fibers would curl and deform during the process of single-sided airflow drying, resulting in a structural feature in which multiple pieces of corn flake feed were curled, intertwined and entangled with each other. Based on this discovery, the inventors of this case believed that this curling feature could be utilized and amplified through appropriate process adjustments, so that the corn flake feed could be curled into a hollow structure as a drug capsid for use in livestock administration and other operations, replacing the currently commonly used blowpipe administration method. Summary of the invention:

[0006] In view of this, it is necessary to provide a corn tablet drug capsid for livestock administration and a production method to solve the above problems.

[0007] The corn tablet drug shell for livestock administration is composed of a gelatinized pressed material of cooked corn kernels, a grass fiber binder and additives.

[0008] Among them, the gelatinized pressed product of mature corn kernels is processed from dried corn kernels. The processing process is as follows: (1) Screening out sundries including gravel and metal; (2) Crushing the dried corn kernels and adding 20% - 30% water by mass, stirring evenly and then standing still; (3) Heating and maintaining at 90 - 110 °C for 40 - 55 minutes, during which part of the water is filtered out by screening, so that the water content of the material decreases to 15% - 17% by mass; (4) Pressing the material and further squeezing out the water therein to form a bent thin sheet with a middle thickness of 2.5 - 3 mm and two-end thicknesses of 1.5 - 2 mm, and the water content is 9% - 11% by mass. The temperature during the pressing process is controlled at 60 - 70 °C; (5) Cutting and then air-drying and cooling. During the air-drying and cooling process, the air blowing direction points to the concave side of the bent thin sheet, forming a gelatinized pressed product of mature corn kernels with a cylindrical curl and converging at both ends.

[0009] The forage fiber binder accounts for 3% - 7% by mass in the corn flake pharmaceutical shell product. Its processing process is as follows: (1) Using silage forage as the raw material, after removing sundries including gravel and metal, adjusting the water content to 10% by mass; (2) Using a roller mill to process the raw material unidirectionally to make it broken into needle-shaped materials with a length of 5 - 15 mm and a diameter of 0.3 - 0.5 mm; (3) Evenly spreading the needle-shaped materials on the material plate and paving them flat, with a laying thickness of 0.8 - 1.1 mm, adding a liquid slurry containing 4% - 6% corn starch by mass and standing still and precipitating for 30 minutes in an environment of 40 - 50 °C, so that the needle-shaped materials are bonded into a net by the precipitated corn starch, that is, forming the forage fiber binder; (4) The forage fiber binder is attached to the above-mentioned gelatinized pressed product of mature corn kernels to form the addition of the forage fiber binder to the corn flake pharmaceutical shell.

[0010] The additive accounts for no more than 20% by mass in the corn flake pharmaceutical shell product, including baking soda, corn cob powder and functional additives.

[0011] This product itself can be directly used as feed for feeding. It contains 3% - 7% silage forage fiber by mass and is pressed into shape together with the corn flakes in a net shape, completely avoiding the layering problem of silage and corn flakes during use, and making the intake ratio of livestock individuals uniform. After the forage fiber is ingested into the rumen, it is mixed with saliva and gastric digestive juice to be moistened and softened, forming a stimulation to the reticulum, thereby promoting the rumination action of livestock. When administering medicine to livestock, after dripping part of the water in the middle of the cylinder for softening to prevent cracking, the curled part is opened and the medicine is stuffed into the inner cavity of the cylinder, and then it can be administered in the normal feeding method, avoiding the use of methods such as blowpipes, which is not only convenient for operation, but also reduces the uneasiness of livestock and improves the safety of related operations.

[0012] Preferably, the additive accounts for 18% by mass in the corn flake pharmaceutical coating product, including 0.5% of baking soda, 15% - 16% of corn cob powder, and 1.5% - 2.5% of functional additives. Baking soda is mainly used in the product to adjust the pH value of the silage and prevent the acid produced during the anaerobic fermentation of the silage from having an adverse effect on the corn flake product; in this design, corn cob powder is used to reduce the cost of ruminant feed. Although corn cobs contain a large amount of sugar, most animals do not eat unprocessed corn cobs. The common processing method for corn cobs is to grind them into corn cob powder. After being moistened, the corn cob powder is mixed into the conventional feed as an additive. However, due to the feeding habits of ruminants, the corn cob powder commonly used in pig feed has low palatability for ruminants. In this design, the corn cob powder is mixed into the corn flakes and not fed in a paste form, which is more suitable for the feeding habits of ruminants. At the same time, the cost of feed raw materials is significantly reduced.

[0013] Furthermore, the functional additive is a mixture of one or more of trace element supplements, drugs, salts, vitamins, and antimicrobial agents.

[0014] A production method of corn flake pharmaceutical coating for livestock administration, the raw materials including dry corn kernels, silage, and additives, comprising the following steps:

[0015] 1) Processing of dry corn kernels: 1-1. Screening out impurities including gravel and metal; 1-2. Crushing the dry corn kernels into powders with a diameter of 0.5 - 1.3 mm, adding water with a mass ratio of 20% - 30%, stirring evenly and then standing at room temperature; 1-3. Heating with steam to 90 - 110 °C and maintaining for 40 - 55 minutes to completely gelatinize the material. During this period, part of the water is discharged by means of a sieve plate, so that the water content of the material decreases to 15% - 17% by mass; 1-4. Using a concave mold to press the material in an environment of 60 - 70 °C and further squeeze out the water therein, so that the material forms a curved thin sheet with a middle thickness of 2.5 - 3 mm, a thickness of 1.5 - 2 mm at both ends, and a water content of 9% - 11% by mass; 1-5. Cutting and then air-drying and cooling. During the air-drying and cooling period, the air blowing direction points to the concave side of the curved thin sheet, forming a gelatinized pressed product of cooked corn kernels with a cylindrical curl and converging ends.

[0016] 2) Processing of silage: 2-1. Screening out sundries including gravel and metal; 2-2. Adjusting the water content to 10% by mass ratio through sun drying or sprinkling water; 2-3. Using a roller to unidirectionally crush the material to form needle-shaped materials with a length of 5 - 15 mm and a diameter of 0.3 - 0.5 mm; 2-4. Uniformly spreading the needle-shaped materials on a material plate and leveling them, with a laying thickness of 0.8 - 1.1 mm, adding a liquid slurry containing corn starch with a mass ratio of 4% - 6%, and standing and precipitating for 30 minutes in an environment of 40 - 50 °C, so that the needle-shaped materials are bonded into a reticular forage fiber adhesive by the precipitated corn starch; 2-5. Using the forage fiber adhesive as a sieve plate to combine with the corn kernel material in the above steps 1-3.

[0017] 3) Evaporating, precipitating or adding water to part of the water discharged by the sieve plate method in the above steps 1-3 and part of the water discharged by squeezing and filtering in step 1-4, adjusting its corn starch content to 4% - 6% by mass ratio, and then using it as a liquid slurry in the above step 2-4.

[0018] 4) Adding materials into the corn tablet drug coating in the above steps 1-2, 2-4 or 1-5, and the adding materials account for no more than 20% by mass ratio in the corn tablet drug coating product.

[0019] In the above production process, in steps 1-3 and 1-4, the excess water is removed by filtering with a forage fiber mesh, replacing the original steam drying method, greatly reducing energy consumption. At the same time, the slurry containing corn starch filtered out is precipitated and reused in step 2-4 to bond the forage fiber mesh, and the clarified liquid after precipitation can be directly recycled and reused in step 1-2 or 2-2. Compared with the original steam recovery water method, the recovery rate is greatly improved, and the water-saving effect is remarkable.

[0020] In the process parameter test, some phenomena are obtained. During the one-sided air supply and air drying process of the laminate of cooked corn kernel gelatinized pressings and reticular plant fiber materials, when the wind speed and temperature remain unchanged, the curling degree of the sheet laminate is negatively correlated with the thickness of the sheet laminate within the test range. Based on this, in this case, in process 1-4, the material is pressed by a mold into a concave bend with thin ends and thick middle. During the subsequent air drying process, the bending degree at both ends is higher than that in the middle, so as to form a tubular structure with converging ends and a hollow interior in the product, which is used to wrap the drug to achieve the function of the coating.

[0021] The additive accounts for 18% by mass in the corn flake pharmaceutical coating product, including 0.5% of baking soda. This ratio is a general empirical value and should be adjusted accordingly for silage with significantly different storage environments and storage times. Needle-shaped materials are added in steps 2-4 to adjust the pH value of the silage and prevent the acid produced during anaerobic fermentation of the silage from having an adverse effect on the corn flake product. Corn cob powder accounts for 15% - 16%. Since corn cob powder can remain stable at the pressing process temperature, the powder is added in steps 1-2. The functional additive accounts for 1.5% - 2.5%. Among them, the components that can remain stable at the process temperature are added together with the corn cob powder in steps 1-2, and the components that will deteriorate or volatilize at the process temperature are added during the cooling and air-drying process in steps 1-5 and adhered to the surface of the product.

[0022] The above-mentioned functional additive is a mixture of one or more of trace element supplements, drugs, salts, vitamins, and antimicrobial agents. Among them, salts, antimicrobial agents, and non-volatile trace element supplements are added in steps 1-2, and volatile trace element supplements, drugs, and vitamins are added in steps 1-5.

[0023] Preferably, in steps 1-5, the air flow temperature is 30 - 33 degrees Celsius, and a ventilation pipe with a diameter not greater than one-third of the width of the curved thin sheet is used to direct ventilation. In the process parameter tests that have been carried out, the finished product rate of the curled state of the air-dried product in this scheme is higher than other schemes.

[0024] Furthermore, the wind speed in the ventilation pipe is 0.4 - 0.5 meters per second, and the duration of steps 1-5 is 10 - 12 minutes.

[0025] The present invention provides a corn flake pharmaceutical coating for livestock administration and a production method. By adding a forage fiber adhesive to the corn flake product, the problems that corn flakes fed to ruminants are likely to cause reduced rumination, rumen impaction, and flatulence are solved. At the same time, the production process is improved in combination with the characteristics of the forage fiber adhesive, significantly reducing the energy consumption and water consumption in the production process of corn flakes. Through the adjustment of the process scheme, a curled hollow cylindrical product is also formed, which can be used to wrap drugs for livestock administration, replacing existing operations such as blowpipes, reducing the corresponding work difficulty and improving operation safety. Specific embodiments:

[0026] The corn flake pharmaceutical coating for livestock administration is composed of a gelatinized pressing of cooked corn kernels, a forage fiber adhesive, and an additive.

[0027] Among them, the gelatinized pressed product of cooked corn kernels is processed from dried corn kernels, and the processing process is as follows: (1) Remove sundries including gravel and metal; (2) After crushing the dried corn kernels, add water with a mass ratio of 20% - 30%, stir evenly and then let stand; (3) Heat and maintain at 90 - 110 °C for 40 - 55 minutes, during which part of the water is filtered out by sieving, so that the water content of the material decreases to 15% - 17% by mass ratio; (4) Press the material on the working surface of the concave mold and further squeeze out the water therein to form a curved thin sheet with a middle thickness of 2.5 - 3 mm, a thickness of 1.5 - 2 mm at both ends, and a water content of 9% - 11% by mass ratio. The temperature during the pressing process is controlled at 60 - 70 °C; (5) After cutting, air-dry and cool. During the air-drying and cooling process, the air blowing direction points to the concave side of the curved thin sheet to form a gelatinized pressed product of cooked corn kernels with a cylindrical curl and convergent ends.

[0028] The forage fiber adhesive accounts for 3% - 7% by mass ratio in the corn tablet pharmaceutical shell product. Its processing process is as follows: (1) The silage forage is used as the raw material. After removing sundries including gravel and metal, adjust the water content to 10% by mass ratio; (2) Use a roller mill to process the raw material unidirectionally to break it into needle-shaped materials with a length of 5 - 15 mm and a diameter of 0.3 - 0.5 mm; (3) Evenly sprinkle the needle-shaped materials on the material plate and flatten them. The laying thickness is 0.8 - 1.1 mm. Add a liquid slurry containing corn starch with a mass ratio of 4% - 6% and let it stand and precipitate for 30 minutes in an environment of 40 - 50 °C, so that the needle-shaped materials are bonded into a network by the precipitated corn starch, that is, the forage fiber adhesive is formed; (4) The forage fiber adhesive is bonded to the above-mentioned gelatinized pressed product of cooked corn kernels to form the addition of the forage fiber adhesive to the corn tablet pharmaceutical shell.

[0029] The additive accounts for no more than 20% by mass ratio in the corn tablet pharmaceutical shell product, and includes baking soda, corn cob powder and functional additives.

[0030] Additives comprise 18% by weight of the corn tablet drug shell product, including 0.5% baking soda, 15%-16% corncob meal, and 1.5%-2.5% functional additives. Baking soda is primarily used to adjust the pH of silage, preventing the acid produced during anaerobic fermentation from adversely affecting the corn tablet product. Corncob meal is used in this design to reduce ruminant feed costs. Although corncobs contain a large amount of sugar, most animals do not eat raw corncobs. Corncob meal is typically ground into corncob meal, moistened, and mixed into conventional feed. However, due to the feeding habits of ruminants, corncob meal, commonly used in pig feed, is not very palatable. In this design, corncob meal is mixed into the corn tablets, rather than being fed in a paste form, making it more suitable for ruminant feeding habits. This significantly reduces feed ingredient costs. Functional additives are a mixture of one or more of trace element supplements, medications, salts, vitamins, and antimicrobials.

[0031] The product itself can be fed directly as feed. It contains 3% to 7% by mass of silage fiber and is compressed into a mesh shape together with corn flakes. During use, the stratification problem of silage and corn flakes is completely avoided, ensuring a uniform intake ratio for individual livestock. After being ingested into the rumen, the silage fiber mixes with saliva and gastric digestive juices to moisten and soften, stimulating the reticulum and thus promoting rumination in livestock. When administering the drug to livestock, some water is dripped into the middle of the cylinder to soften it and prevent brittle cracking. After that, the curled part is stretched open and the drug is inserted into the cavity inside the cylinder. This allows for normal feeding and avoids the use of methods such as blowpipes. This is convenient for operation, reduces livestock's sense of unease, and improves the safety of related operations.

[0032] A method for producing corn tablet drug capsids, used for producing the above-mentioned corn feed, wherein the raw materials include dried corn kernels, silage and additives, comprises the following steps:

[0033] 1) Processing of dried corn kernels: 1-1. Screening out impurities including gravel and metal; 1-2. Crushing the dried corn kernels into powders with a diameter of 0.5 - 1.3 mm, adding water with a mass ratio of 20% - 30%, stirring evenly and then standing at room temperature; 1-3. Heating with steam to 90 - 110 °C and maintaining for 40 - 55 minutes to completely gelatinize the material. During this period, part of the water is discharged by means of a sieve plate, so that the water content of the material decreases to 15% - 17% by mass ratio; 1-4. Using a concave mold to press the material at 60 - 70 °C and further squeezing out the water therein, so that the material forms a bent thin sheet with a middle thickness of 2.5 - 3 mm, a thickness of 1.5 - 2 mm at both ends, and a water content of 9% - 11% by mass ratio; 1-5. After cutting, use a ventilation pipe with a diameter not greater than one-third of the width of the bent thin sheet to point to the concave surface of the thin sheet for ventilation and air drying and cooling. During the air drying and cooling period, the air flow speed is 0.4 - 0.5 m per second, the temperature is 30 - 33 °C, and the air drying time is 10 - 12 minutes, so that the bent thin sheet is further curled to form a cooked corn kernel gelatinization pressed product with a tubular curl and converging ends.

[0034] 2) Processing of silage: 2-1. Screening out impurities including gravel and metal; 2-2. Adjusting the water content to 10% by mass ratio by means of sun drying or watering; 2-3. Using a roller to unidirectionally crush the material to break it into needle-shaped materials with a length of 5 - 15 mm and a diameter of 0.3 - 0.5 mm; 2-4. Evenly spreading the needle-shaped materials on a material plate and paving them flat, with a laying thickness of 0.8 - 1.1 mm, adding a liquid slurry containing corn starch with a mass ratio of 4% - 6% and standing and precipitating for 30 minutes in an environment of 40 - 50 °C, so that the needle-shaped materials are bonded into a net-like forage fiber adhesive by the precipitated corn starch; 2-5. The forage fiber adhesive is used as a sieve plate to be combined with the corn kernel material in the above step 1-3.

[0035] 3) For the part of the water discharged by the sieve plate method in the above step 1-3 and the part of the water squeezed out in step 1-4, perform evaporation or precipitation or water addition treatment, and adjust its corn starch content to 4% - 6% by mass ratio, and then use it as a liquid slurry in the above step 2-4.

[0036] 4) The additive is incorporated into the corn tablet pharmaceutical coating in the above step 1-2 or 2-4 or 1-5, and the additive accounts for no more than 20% by mass ratio in the corn tablet pharmaceutical coating product.

[0037] In the above production process, in steps 1-3 and 1-4, the redundant moisture is removed by filtering with a forage fiber mesh, replacing the original steam drying method, significantly reducing energy consumption. Meanwhile, the slurry containing corn starch filtered out is precipitated and reused for bonding the forage fiber mesh during step 2-4. The clarified liquid after precipitation can be directly recycled and reused for step 1-2 or 2-2. Compared with the original steam condensate recovery method, the recovery rate is greatly increased, and the water-saving effect is remarkable.

[0038] Some phenomena were obtained in the process parameter tests. During the unilateral air-drying process of the laminate of gelatinized and pressed cooked corn kernels and reticulated plant fiber materials, when the wind speed and temperature remained unchanged, the degree of curling of the sheet laminate was negatively correlated with the thickness of the sheet laminate within the test range. Based on this, in this case, in process 1-4, the material is pressed by a mold into a concave bend with thin ends and thick middle. During the subsequent air-drying process, the bending degree at both ends is higher than that in the middle, so as to form a cylindrical structure with converging ends and a hollow interior in the product, which is used to wrap the drug to achieve the function of the coat.

[0039] The additive accounts for 18% by mass in the corn tablet drug coat product, including 0.5% of baking soda. This ratio is a general empirical value and should be adjusted accordingly for silage forages with too large differences in storage environment and storage time. Needle-shaped materials are added in step 2-4 to adjust the pH value of the silage forage and prevent the acid generated during the anaerobic fermentation of the silage forage from having an adverse effect on the corn tablet product. Corn cob powder accounts for 15% - 16%. Since the corn cob powder can remain stable at the pressing process temperature, the powder is added in step 1-2. The functional additive accounts for 1.5% - 2.5%. Among them, the components that can remain stable at the process temperature are added together with the corn cob powder in step 1-2, and the components that will deteriorate or volatilize at the process temperature are added and adhered to the surface of the product during the cooling and air-drying process in step 1-5.

[0040] The above functional additive is a mixture of one or more of trace element supplements, drugs, salts, vitamins, and antimicrobial agents. Among them, salts, antimicrobial agents, and non-volatile trace element supplements are added in step 1-2, and volatile trace element supplements, drugs, and vitamins are added in step 1-5.
