Specifically, the reason for the rapid loss of vitamin A in the formula powder after opening the lid is that vitamin A itself is unstable and is easily affected by light, oxygen, high temperature and acid. When vitamin A is exposed to light with a wavelength less than 500 nanometers, it is easily destroyed, resulting in loss; and the vitamin B2 present in the formula powder as a strong photosensitizer can absorb visible light and ultraviolet light and convert into highly active forms of oxygen, and a series of oxygen reactions may also lead to a sharp reduction in vitamin A; the embedded vitamin A powder raw material breaks during the wet mixing process, resulting in vitamin A exposed to the surface of the powder particles after the drying process, and the vitamin A on the surface of the powder is oxidized and rapidly degraded during the can opening test. Based on this, the formula powder preparation method of some embodiments of the present disclosure, first, the oily vitamin A and the premixed oil are mixed to obtain a hot oil mixture. Thus, the oily vitamin A can be dissolved in the premixed oil. The hot oil mixture and the pre-configured material set are prepared to obtain a mixed material. Thus, the vitamin A in the hot oil mixture can be mixed with the pre-configured material. The mixed material is spray dried to obtain a formula powder. Thus, during the drying process, the hot oil mixture can be embedded in the pre-configured material, thereby protecting it from contact with oxygen during storage or unpacking, and other vitamins (including vitamin B2) are subsequently prepared as materials in the form of vitamin pre-mixed powder, which is not carried out at the same time as vitamin A, thereby reducing the impact of vitamin B2 on vitamin A during oxygen reaction, thereby reducing the loss of vitamin A.

Referring to FIG1 , a process 100 of some embodiments of a method for preparing a formula powder according to the present disclosure is shown. The method for preparing a formula powder comprises the following steps:

Step 101, mixing the oily vitamin A and the premixed oil to obtain a hot oil mixture.

In some embodiments, the execution body of the formula powder preparation method (for example, the formula powder preparation equipment, the formula powder preparation equipment may include: process robots, hot oil tanks, mixers, drying towers, conveyor belts and other equipment) may mix the oily vitamin A and the premixed oil to obtain a hot oil mixture. Among them, the oily vitamin A may be vitamin A that can be dissolved in oil. For example, the oily vitamin A may include any one of the following vitamin A palmitate retinyl ester oil, retinyl acetate, all-trans retinol and β-carotene. The premixed oil may be various oils used to prepare formula powder. For example, the premixed oil may include but is not limited to at least one of the following: sunflower oil, low-erucic acid rapeseed oil and medium-chain triglycerides. Here, the specific oil type and formula amount included in the premixed oil are not limited. The user can adjust according to the specific formula powder parameters. In practice, the execution body may add the oily vitamin A to the premixed oil and mix and stir at a preset temperature to obtain a hot oil mixture.

Step 102, preparing the hot oil mixture and the pre-configured material set to obtain a mixed material.

In some embodiments, the execution entity may prepare the hot oil mixture and the pre-configured material set to obtain a mixed material. The pre-configured material set may be various materials used to prepare formula powder. For example, the pre-configured material set may include but is not limited to at least one of the following: concentrated milk protein powder, maltodextrin, white sugar, inulin, sodium citrate and potassium chloride. Here, there is no limitation on the specific material types and formula quantities included in the pre-configured material set. The user may adjust it according to the specific formula powder parameters. In practice, the execution entity may prepare the hot oil mixture and the pre-configured material set through an online mixer to obtain a mixed material. The online mixer may be an online mixer combined with a stirring paddle and a circulation pipeline of a mixing tank. The online mixer may have a shearing function.

In some optional implementations of some embodiments, the execution subject may prepare the hot oil mixture and the pre-configured material set to obtain a mixed material by executing the following steps: according to a preset configuration ratio, the hot oil mixture and each pre-configured material in the pre-configured material set are stirred to obtain a mixed material. The preset configuration ratio may be a preset ratio of each material. In practice, according to the preset configuration ratio, the execution subject may stir the hot oil mixture and each pre-configured material in the pre-configured material set through an online mixer to obtain a mixed material. The stirring speed may be greater than or equal to 2200rpm/min. Specifically, the execution subject may also stir the hot oil mixture, each pre-configured material in the pre-configured material set and reverse osmosis water through an online mixer to obtain a mixed material. The temperature range of the reverse osmosis water may be 80~60℃.

Step 103, drying the mixed material to obtain formula powder.

In some embodiments, the execution entity may dry the mixed material to obtain a formula powder.

In some optional implementations of some embodiments, the execution subject may perform spray drying on the mixed material to obtain a formula powder by performing the following steps:

The first step is to sterilize the above-mentioned mixed material to obtain a sterilized mixed material. In practice, the above-mentioned execution entity can homogenize and pasteurize the above-mentioned mixed material to obtain a sterilized mixed material. The homogenization temperature can range from 70 to 100°C. The homogenization pressure can range from 140 to 310 bar (G). The pasteurization temperature range can be 50 to 80°C. It should be noted that in the process of homogenizing and pasteurizing the above-mentioned mixed material, the flow rate of the above-mentioned mixed material can be less than or equal to 3000L/h.

The second step is to spray dry the sterilized mixed material at a target spray gun inclination angle to obtain a dried mixed material. The target spray gun inclination angle may be a spray gun angle that allows the droplets sprayed from the spray gun to gather to form larger droplets. For example, the target spray gun inclination angle may be a preset angle. As an example, the target spray gun inclination angle may be 90°. Thus, by adjusting the angle of the spray gun, the droplets sprayed from the spray gun can gather to form larger droplets, thereby increasing the particle size of the intermediate powder after the droplets are dried, thereby reducing the bulk density of the powder, and thereby improving the solubility of the formula powder.

The third step is to cool the dried mixed material to obtain a cooled mixed material. In practice, the execution body may cool the dried mixed material through a fluidized bed device to obtain a cooled mixed material.

In some optional implementations of some embodiments, at a target spray gun tilt angle, the execution subject may spray dry the sterilized mixed material by performing the following steps to obtain a dried mixed material:

At the target spray gun inclination angle, the sterilized mixed material is spray dried and repolymerized to obtain a dried mixed material. In practice, first, the above-mentioned execution body can input the above-mentioned sterilized mixed material into a drying tower. Then, the above-mentioned sterilized mixed material can be sprayed out from the atomizing nozzle by a high-pressure pump to obtain a primary dried mixed material. After that, the above-mentioned execution body can send the fine powder in the primary dried mixed material back to the top of the drying tower for repolymerization (the proportion of fine powder to be sent back to the top of the drying tower for repolymerization is determined according to the bulk density of the formula powder) to the top of the above-mentioned drying tower for repolymerization, and the remaining powder is used as the dried mixed material.

The following technical problems also exist when preparing formula powder: fine powder will cause static electricity, which is easy to adhere to the inner surface of the equipment and the outer surface of the can during the canning process, causing material loss.

The above-mentioned spray drying and polymerization treatment step is an inventive point, which solves the above-mentioned technical problems. Specifically, the adjustment of the powder particles by polymerization in the process can make the particle size of the obtained particles more in line with the requirements, thereby reducing fine powder and static electricity, and further reducing the adhesion on the inner surface of the equipment and the outer surface of the tank, reducing the loss of materials during the preparation process.

Specifically, in order to improve the solubility and increase the particle size of the powder, the execution subject may spray dry and polymerize the sterilized mixed material by adopting the following polymerization methods:

The first type: as shown in Figure 5, forced primary recombination:

In the first step, the angle of each of the at least two spray guns in the drying tower is adjusted so that the particles sprayed from each of the at least two spray guns collide with each other.

In the second step, the sterilized mixed material is spray dried and polymerized by at least two spray guns with adjusted angles to obtain a dried mixed material, thereby increasing the particle size of the droplets and thus increasing the particle size of the powder after the droplets are dried.

The second type, as shown in Figure 6, is forced secondary recombination:

In the first step, the angle of each of the at least two spray guns in the drying tower is adjusted so that the particles sprayed from each of the at least two spray guns collide with each other.

The second step is to spray dry the sterilized mixed material to obtain a primary dried mixed material.

The third step is to determine the proportion of recovered fine powder according to the preset bulk density information. In practice, first, the above-mentioned execution subject can detect the bulk density of the mixed material after the initial drying to obtain the material bulk density information. Then, in response to determining that the above-mentioned material bulk density information is greater than or equal to the preset bulk density information, the first preset proportion of recovered fine powder is determined as the proportion of recovered fine powder. In response to determining that the above-mentioned material bulk density information is less than the preset bulk density information, the second preset proportion of recovered fine powder is determined as the proportion of recovered fine powder. Among them, the above-mentioned first preset proportion of recovered fine powder is greater than the above-mentioned second proportion of recovered fine powder. The above-mentioned proportion of recovered fine powder can be the proportion of the required recovered fine powder in the total number of fine powders.

In the fourth step, according to the above-mentioned recovered fine powder ratio, the fine powder recovered during the drying process by the cyclone separator and bag filter included in the above-mentioned drying tower is transmitted to the top of the tower.

The fifth step is to perform a re-aggregation treatment on the recovered fine powder. In practice, the execution subject can spray the recovered fine powder from the fine powder output pipe again. The particles sprayed from the fine powder output pipe can collide with the particles sprayed from each of the at least one spray gun.

In the sixth step, the fine powder sprayed out again and the unrecovered fine powder in the above-mentioned mixed material after the initial drying are determined as the mixed material after drying.

In addition to the two main reunions mentioned above, there is another type of reunion:

Spontaneous secondary polymerization:

As shown in Figure 7, this reagglomeration is caused by the Venturi effect at the hot air inlet of the drying tower, and the dry fine powder is sucked into the atomization area. The wet particles collide with the dry fine powder entrained in the reverse exhaust gas in the drying tower and reagglomerate. Therefore, the particle size of the intermediate powder is increased through reagglomeration, the bulk density of the powder is reduced, and the solubility of the formula powder is improved.

It should be noted that there is a certain relationship between bulk density and particle size, but it is not directly proportional. Bulk density is affected by many factors, of which particle size is only one of them. The following are some general rules related to bulk density and particle size:

Particle size and bulk density: Generally, smaller particles are more likely to fill voids when forming a bulk body, so their bulk density may be higher. Larger particles may have a lower bulk density because they form larger voids.

Particle shape: Particles of different shapes also affect bulk density. Regularly shaped particles are usually able to pack more tightly, resulting in a higher bulk density, while irregularly shaped particles may form a more open structure, resulting in a lower bulk density.

Interactions between particles: Interactions between particles, such as adsorption, electrostatic forces, etc., also affect bulk density. These interactions can cause particles to pack more closely.

Humidity: Humidity has a significant effect on the surface properties of the granules, thus affecting the bulk density. Wet granules are likely to aggregate together to form a more compact packing.

In general, the relationship between bulk density and particle size is complex and is affected by multiple factors. Therefore, in research and engineering applications, factors such as particle size, shape, surface properties, and environmental conditions need to be considered comprehensively to more accurately understand and control bulk density. Some specific numerical ranges in the spray drying process are as follows: bulk density 0.33~0.53g/ml, tap density 0.45~0.65g/ml, and moisture content less than or equal to 4.0%.

Next, when the formula powder is prepared by the present application, the following technical problem 2 further exists:

The particle size of the powder sprayed by the spray gun will also be affected by the spray pressure and the hot air parameters in the drying tower. When only a fixed spray gun tilt angle is used for spraying, the powder aggregation effect is poor, and there is more fine powder, resulting in poor solubility of the formula powder.

In some optional implementations of some embodiments, at a target spray gun tilt angle, the execution subject may spray dry the sterilized mixed material through the following steps to obtain a dried mixed material:

The first step is to spray dry the sterilized mixed material at a preset spray gun tilt angle to obtain an initially dried mixed material.

In the second step, a particle size distribution test is performed on the above-mentioned mixed material after initial drying by a particle size detection device to obtain particle size distribution information. The above-mentioned particle size detection device may be a device for detecting the particle distribution of the above-mentioned mixed material after initial drying. For example, the above-mentioned particle size detection device may be a laser particle size analyzer or a dynamic light scattering instrument. The above-mentioned particle size distribution information may be information characterizing the particle distribution of the above-mentioned mixed material after initial drying. The above-mentioned particle size distribution information may include the particle diameter size and the number of particles corresponding to each type of particle size diameter range. For example, the above-mentioned particle size distribution information may be "(first particle diameter size range, 800), (second particle diameter size range, 800), (third particle diameter size range, 200)". The first particle diameter size range may be (0mm, 1mm]. The second particle diameter size range may be (1mm, 2mm]. The third particle diameter size range may be (2mm, 3mm].

The third step is to detect the moisture content of the initially dried mixed material by a moisture content detection device to obtain moisture content information. The moisture content detection device may be a device for detecting the moisture content of the initially dried mixed material. For example, the moisture content detection device may be an online moisture meter or an infrared moisture meter.

The fourth step is to determine whether the above-mentioned particle size distribution information satisfies a preset particle size distribution condition. The above-mentioned preset particle size distribution condition may be that the number of particles in each particle diameter size range in the above-mentioned particle size distribution information is within a preset particle number range. As an example, the number of particles corresponding to the first particle diameter size range is within a preset first particle number range, and the number of particles corresponding to the second particle diameter size range is within a preset second particle number range, and the number of particles corresponding to the third particle diameter size range is within a preset third particle number range.

The fifth step is to determine whether the moisture content information satisfies a preset moisture content condition, wherein the preset moisture content condition may be that the moisture content information is within a preset moisture content range.

In the sixth step, in response to determining that the particle size distribution information does not meet the preset particle size distribution condition or the moisture content information does not meet the preset moisture content condition, the particle size distribution information and the moisture content information are input into the pre-trained drying tower parameter information generation model to obtain the target drying tower parameter information. Wherein, the target drying tower parameter information may include target injection pressure, target hot air parameter and target spray gun tilt angle. The target injection pressure may characterize the pressure of the spray gun of the drying tower. The target hot air parameter may characterize various parameters of the hot air in the drying tower. The target hot air parameter may include hot air temperature and hot air flow rate. The spray gun tilt angle generation model may be a machine learning model with particle size distribution information and moisture content information as input and target drying tower parameter information as output. The spray gun tilt angle generation model may include an input layer, a target injection pressure generation layer, a target hot air parameter generation layer, a target spray gun tilt angle generation layer and an output layer. The input layer may be used to perform feature processing on the particle size distribution information and the moisture content information to obtain particle size distribution feature information and moisture content feature information. The target spray pressure generation layer may be a first regression model for generating a target spray pressure according to the particle size distribution characteristic information and the moisture content characteristic information. The target hot air parameter generation layer may be a second regression model for generating a target hot air parameter according to the particle size distribution characteristic information and the moisture content characteristic information. The target spray gun tilt angle generation layer may be a third regression model for generating a target spray gun tilt angle according to the particle size distribution characteristic information and the moisture content characteristic information. The output layer may be used to combine the target spray pressure generation layer, the target hot air parameter generation layer, and the target spray gun tilt angle generation layer to generate target drying tower parameter information.

The seventh step is to spray dry the sterilized mixed material according to the target spray pressure, target hot air parameters and target spray gun tilt angle included in the target drying tower parameter information to obtain a dried mixed material.

The above-mentioned related contents, as an inventive point of the embodiment of the present disclosure, solve the second technical problem "the particle size of the powder sprayed by the spray gun is also affected by the spray pressure and the hot air parameters in the drying tower. When only a fixed spray gun tilt angle is used for spraying, the effect of powder aggregation is poor, resulting in a low bulk density of the powder, which leads to poor solubility of the formula powder". The factors that lead to poor solubility of the formula powder are often as follows: the particle size of the powder sprayed by the spray gun is also affected by the spray pressure and the hot air parameters in the drying tower. When only a fixed spray gun tilt angle is used for spraying, the effect of powder aggregation is poor, resulting in a low bulk density of the powder. If the above factors are solved, the effect of solubility of the formula powder can be achieved. In order to achieve this effect, the present disclosure can detect the particle size distribution and moisture content of the sprayed powder. When the particle size distribution or moisture content is unqualified, the spray pressure, hot air parameters and spray gun tilt angle of the drying tower are adjusted according to the particle size distribution and moisture content of the powder, so that the effect of powder aggregation is better, thereby improving the bulk density of the powder, and then improving the solubility of the formula powder.

In some optional implementations of some embodiments, the execution subject may spray dry the sterilized mixed material to obtain a dried mixed material by performing the following steps: spray dry the sterilized mixed material through a drying tower to obtain a dried mixed material. The main air inlet temperature of the drying tower may range from 160 to 190°C, and the main exhaust temperature of the drying tower may range from 70 to 110°C.

In some optional implementations of some embodiments, the execution subject may cool the dried mixed material to obtain a formula powder by performing the following steps: Cool the dried mixed material by a fluidized bed device to obtain a formula powder. The fluidized bed device includes a static fluidized bed and a dynamic fluidized bed. The inlet air temperature range of the static fluidized bed may be 80~100°C. The inlet air temperature range of the first stage of the dynamic fluidized bed may be 40~60°C. The inlet air temperature range of the second stage of the dynamic fluidized bed may be 10~30°C. The temperature range of the formula powder may be 20~40°C.

Optionally, after cooling the dried mixed material to obtain the formula powder, the execution body may further perform the following steps:

The first step is to can the formula powder through sterilized empty cans to obtain canned formula powder. In practice, the execution entity can can the sieve formula powder into an empty can that has been sterilized by ultraviolet light to obtain canned formula powder. Before canning, the execution entity can also sieve the formula powder through a sieve. The size of the sieve can be 2 mm*2 mm.

The second step is to weigh the canned formula powder to obtain the weighed formula powder.

The third step is to pre-seal the weighed formula powder to obtain the pre-seal formula powder. In practice, the execution body may sterilize the bottom cover with ultraviolet light to pre-seal the weighed formula powder to obtain the pre-seal formula powder.

The fourth step is to perform nitrogen filling and sealing treatment on the pre-sealed formula powder to obtain sealed formula powder.

Thus, by sieving, canning, weighing, pre-sealing and nitrogen-sealing the formula powder, the formula powder can be packaged for subsequent storage and transfer.

Furthermore, the above-mentioned execution entity can also perform subsequent processing such as coding, capping, optical and mechanical inspection, packaging, and warehousing on the sealed formula powder, and store the formula powder in the warehouse.

According to experimental data, the formula powder prepared by the above formula powder preparation method can be stably stored for at least 24 months in the original unopened container at room temperature. If it is stored at a higher ambient temperature (about 37°C), the product can be stable for at least 6 months.

In order to prove the effect of the formula powder prepared by the above formula powder preparation method, the following test methods and test results are provided.

First, this experiment kept the formula unchanged and under the same process production conditions, respectively, using embedded vitamin A powder and retinyl palmitate (palmitate vitamin A) to prepare Deruiyi formula powder. The two Deruiyi formula powders were tested for can opening, and the vitamin A content at T0, 7th day, 14th day, and 21st day was detected and the data was summarized for analysis. The test results are as follows:

As shown in Figure 2, 01 represents the Deruiyi formula powder prepared with vitamin A powder after embedding treatment. 02 represents the Deruiyi formula powder prepared with retinyl palmitate (palmitate vitamin A). The attenuation trend of vitamin A in the two Deruiyi formula powders is similar, and the main attenuation occurs in the first 14 days. The target range of vitamin A in formula powder is 170~609µg/100g. The vitamin A test result of Deruiyi formula powder prepared with retinyl palmitate (palmitate vitamin A) is still within the target range after opening the can for three weeks, while the vitamin A test result of Deruiyi formula powder prepared with vitamin A powder after embedding treatment is lower than the target range.

As shown in Figure 3, the vitamin A attenuation of the two Deruiyi formula powders in the can opening test was compared. During the can opening test, the vitamin A attenuation in the Deruiyi formula powder prepared with retinyl palmitate (vitamin A palmitate) was significantly better than that in the Deruiyi formula powder prepared with encapsulated vitamin A powder.

Secondly, in order to verify the feasibility of replacing raw materials in other powder products, retinyl palmitate (vitamin A palmitate) was also used to prepare Deruibo formula powder. As shown in Figure 4, the results of the bag opening test showed that the degradation rate of vitamin A was relatively slow within three weeks of the bag opening test, and the vitamin A after the three-week test was only reduced by 15%, which was also in line with expectations.

Finally, according to the test results, it can be concluded that the use of retinyl palmitate (palmitic vitamin A) to replace the embedded vitamin A powder in the premix in the original formula can effectively reduce the attenuation of vitamin A during the use of the product after opening the package. The vitamin A content of Deruiyi and Deruibo products is still within the target range after three weeks of opening the package. The improvement plan of replacing raw materials has been confirmed to extend the opening test time of Deruiyi to three weeks, and is applicable to other powder products produced by wet mixing and spray drying process.

The above-mentioned embodiments of the present disclosure have the following beneficial effects: the formula powder prepared by the formula powder preparation method of some embodiments of the present disclosure can reduce the rate of loss of vitamin A in the formula powder after opening the lid. Specifically, the reason for the rapid loss of vitamin A in the formula powder after opening the lid is that vitamin A itself is unstable and is easily affected by light, oxygen, high temperature and acid. When vitamin A is exposed to light with a wavelength less than 500 nanometers, it is easily destroyed, resulting in loss; and the vitamin B2 present in the formula powder as a strong photosensitizer can absorb visible light and ultraviolet light and convert into highly active forms of oxygen, and a series of oxygen reactions may also lead to a sharp reduction in vitamin A; the embedded vitamin A powder raw material breaks during the wet mixing process, resulting in vitamin A exposed to the surface of the powder particles after the drying process, and the vitamin A on the surface of the powder is oxidized and rapidly degraded during the can opening test. Based on this, the formula powder preparation method of some embodiments of the present disclosure, first, the oily vitamin A and the premixed oil are mixed to obtain a hot oil mixture. Thus, the oily vitamin A can be dissolved in the premixed oil. The hot oil mixture and the pre-configured material set are prepared to obtain a mixed material. Thus, the vitamin A in the hot oil mixture can be mixed with the pre-configured material. The mixed material is spray dried to obtain a formula powder. Thus, during the drying process, the hot oil mixture can be embedded in the pre-configured material, thereby protecting it from contact with oxygen during storage or unpacking, and other vitamins (including vitamin B2) are subsequently prepared as materials in the form of vitamin pre-mixed powder, which is not carried out at the same time as vitamin A, thereby reducing the impact of vitamin B2 on vitamin A during oxygen reaction, thereby reducing the loss of vitamin A.
