Description
Technical Field
the invention relates to the field of selenium-rich products and a preparation process thereof, in particular to an antioxidant plant source high organic selenium particle and a preparation method thereof.
Background
selenium element is an indispensable trace element for people, 50 micrograms of selenium is a daily necessary trace element for human bodies, and the selenium can enhance the immune function of the human bodies, resist oxidation, delay senility, effectively inhibit tumor growth and has good auxiliary improvement effect on patients after operation and radiotherapy and chemotherapy treatment.
the scientific research shows that the level of blood selenium is closely related to the occurrence of cancer, and a large amount of research data show that the level of selenium in food and soil in one area is directly related to the incidence rate of cancer. Selenium is the most important anti-aging element discovered to date; however, most areas in China are areas lacking selenium, so that selenium supplement needs to be taken in a manual supplement mode to a great extent, and the content of the selenium supplement is obviously lower than the requirement standard when the selenium supplement is taken in a pure normal food.
selenium can be present in a manner broadly classified into organic selenium and inorganic selenium, which is not available for human or animal consumption and is poisoned. People can supplement selenium only through organic selenium, and through research, the best selenium supplement mode is currently on the market, namely the selenium-enriched yeast supplement is performed through yeast selenium, or all foods made of the selenium-enriched yeast are ingested, but the obvious problem exists:
First, the yeast powder is inevitably subjected to a large peculiar smell no matter the yeast powder is eaten alone or is prepared into food for eating, the yeast powder is carried by the yeast, so that people have certain obstacle or difficulty in swallowing, and even most people give up the food due to unacceptable taste. And secondly, the selenium protein powder is supplemented by the finished product of selenium protein powder. However, the oxidized area of the western protein powder is very large due to the very small particle size of the selenoprotein powder, once the powder is unsealed, the oxidized area of the western protein powder is inevitably contacted with air to cause selenoprotein oxidation failure, meanwhile, the western protein powder is very easy to damp, and the phenomenon of bottle sticking is generated once the powder is damp, so that the selenoprotein powder is not easy to take materials, the using amount is controlled, the great waste is caused, and the visual perception is greatly reduced.
overview of the close prior art:
Chinese patent application, application number: 201711402336.0 application date: 2017-12-22. The abstract is as follows:
The invention provides a kind of sunned protein powder, which is composed of selenium-rich algal polysaccharide, collagen powder, soybean protein isolate powder, inulin, cocoa powder, oat bran nutrition powder and enzymolysis ox bone powder according to the weight ratio of 0.77-10: 25-35: 20-30: 15-20: 10-15: 4.23-8: 2-3. The selenium-enriched protein powder provided by the invention is free of any additive, balanced in nutrition, good in solubility, easy to digest and absorb, high in protein content, and capable of effectively improving selenium deficiency symptoms and adjusting sub-health. The preparation method is simple, easy to realize industrialization, and remarkable in economic benefit and social benefit.
The selenium-enriched protein powder in the prior art cannot avoid the problems of easy wetting and oxidation failure.
Disclosure of Invention
In order to solve the problems that the existing selenoprotein powder is easy to oxidize and wet and the like, the application provides a preparation method of an antioxidant plant source high organic selenium particle, which is used for preparing high-concentration selenium-enriched particles, is used for replacing the existing selenoprotein powder, and simultaneously solves the problems that the existing albumen powder is easy to oxidize and wet, so that effective selenium supplement nutrient components lose effectiveness due to oxidation, or the selenium supplement nutrient components are difficult to take quantitatively after being wetted.
in order to achieve the purpose, the technical scheme adopted by the application is as follows:
a preparation method of antioxidant plant source high organic selenium granules comprises the following steps:
s01, respectively weighing the raw materials, the auxiliary materials and the solvent for granulation for later use; the auxiliary materials comprise edible calcium carbonate, maltodextrin and soluble starch, the solvent is water, and the raw materials are selenium-rich plant source powder;
S02, uniformly mixing the raw materials, the auxiliary materials and the solvent in the S01 to obtain a mixture M;
s03, putting the mixture M into a rotary granulator for rotary granulation to obtain particles P;
s04, placing the particles P into a spherical shot blasting machine for shot blasting to obtain spherical particles G;
s05, placing the spherical particles G into a fluidized bed for boiling and drying to obtain the finished product of the high organic selenium particles.
in order to further improve the oxidation resistance of the selenium element, the step S05 further includes a coating process, and since after the granulation and shot blasting, the organic selenium particles may be oxidized only on the surface of the particle sphere due to contact with air, which improves the oxidation resistance by several times compared with the existing powder under the same condition; however, the surface of the spherical particle has no oxidation resistance, and in order to solve the problems of oxidation resistance and moisture on the surface, a coating and film-making process is particularly added to realize the comprehensive oxidation resistance of the spherical particle.
it is worth to be noted that the problem of oxidation resistance of the current finished selenoprotein is easily ignored by people, therefore, most of the current finished selenoprotein exists in a powder form, and therefore, in real life, since selenium supplement is a very long process, the selenium supplement must be taken daily according to the amount, and repeated bottle opening is carried out for a long time, inedible selenoprotein can be sufficiently contacted with air to cause oxidation, so that part, even most of effective components become ineffective components, and the proportion of the ineffective components occupying the selenoprotein components can be calculated by the following formula:
the weight ratio of the failure components is 4 pi r2h rho/(4/3) pi r3 rho
wherein h represents the oxidized thickness of the selenoprotein powder in the exposure period, and rho represents the density of the selenoprotein;
From the above formula, we can study each selenoprotein powder particle as a sphere, and when the oxidized thickness h of selenoprotein in the whole oxidation period is larger than the particle diameter radius r, the oxidation ratio is 100%, that is, all the rest of the uneaten selenoprotein powder is oxidized. The oxidized thickness h is positively correlated with the oxygen concentration and the oxidation contact time, the oxygen concentration in the air is basically an average value, the error of the oxygen content in the air in different urban areas is small, the oxidation contact time is the main influence factor, however, the oxidation speed of the same selenium protein powder is the same, and the oxidized thickness h is larger as long as the oxidation time is longer. On the premise of not taking any protective measures, the smaller the proportion of the selenium protein to be oxidized is, the larger the particle size r of the selenoprotein powder is, so that the longer the time period for the oxidized thickness h to reach the value of r is, the lower the proportion of the ineffective components in unit time is, and the less the effective selenium element is ineffective.
In order to further reduce the oxidation of the selenoprotein particles, the coating steps are as follows:
S051 preparing a coating film-forming material: mixing hydroxypropyl methyl cellulose and triethyl citrate with the mass ratio of 0.68-0.72:1, and placing the mixture into a coating spray gun cavity of a granulating and coating machine;
s052 controlling the environmental parameters of the spherical particles G for high-speed fluidization in the fluidized bed pot of the granulating and coating machine as follows: the air inlet temperature is controlled at 48-55 ℃, and the boiling drying time is 20 min;
S053 under the premise of ensuring that the step S052 is uninterrupted, spraying the film-forming material in the step S051 in a mist shape, carrying out surface contact with the dried spherical particles G, and fixing the film to form a film, so as to form a coating film on the surfaces of the spherical particles G, wherein the thickness of the coating film is controlled to be 0.05mm-0.1 mm.
The application of the coating on the selenoprotein particles is different from the existing coating, the coating is used for preventing the selenoprotein particles from being exposed to the air and being oxidized in contact with the oxygen in the air to cause selenium supplement failure, and the coating is used for shielding the taste or smell of the medicine compared with the existing coating, so that the coating in the application is necessarily thin and is required to form a film-shaped object uniformly on the surface of the selenoprotein particles, and the aim of ensuring air isolation and independent flowability of the particles is fulfilled. The technical points of the coating in the application, which is different from the existing coating, mainly lie in that: first, the particle is subjected to the fluid-bed drying and coating processes in the same equipment but at different times, and the time of contact mixing of the coating film-forming material and the particles is closely controlled. The coating film-forming material can be sprayed out only after the granules are boiled and dried for 20 minutes, and the granules are in a fog form, and the granules are naturally contacted with the existing coating and then repeatedly rolled and adhered to each other to form a polysaccharide type coating which is completely different. Since the content of the plant-derived selenium in the selenoprotein particles is verified according to the standard of the reference intake of dietary nutrients of the residents in China WS/T578.3-2017 before the particles are prepared, otherwise, excessive intake of the selenium can cause negative effects and even harm to the body, and therefore, the content is very important for trace element supplements, and the effect of the selenium is not negligible for tens of millions.
after the particles are dried for 20 minutes by boiling, no matter which material is adopted by the plant source powder, for example, the most common carriers comprise bean sprouts, kidney beans, broccoli and the like, after the particles are dried for 20 minutes by boiling at the temperature of about 50 ℃, the natural flowability of the particles is very good, at the moment, the coating film forming material is sprayed in a mist spraying mode to be contacted with the selenoprotein particles which move irregularly at high speed, the selenoprotein particles can be absorbed at the moment of contact and can quickly form a coating film under the action of drying airflow flowing at high speed, compared with the existing coating process, the process has very large difference in the uniformity degree and the thickness of the coating film, the coating film with the thickness of less than 0.1mm is difficult to form the finished coating film by adopting the existing coating process, the problems of film leakage and incomplete can occur, and the coated particles are larger, this is very noticeable as the larger the area of the exposed drain membrane. It is also worth noting that the coated granules also have significantly increased flowability and moisture resistance, providing convenience for the consumer to take a dose of the granules.
further, the selenium-rich plant source powder in step S01 is prepared in the following manner:
s011 using inorganic compounds or minerals containing sodium selenite and sodium selenate as raw materials;
s012, selecting beer yeast as selenium-rich yeast strain, and converting inorganic compound in S011 or inorganic selenium in mineral matter into organic selenium by using culture medium;
S013, purifying and centrifuging the selenium yeast in the step S012, and preparing a high-concentration selenium yeast solution;
S014 hydrolyzing the selenium yeast by directional enzyme cutting method to obtain hydrolysis solution;
S015, using the hydrolysis solution obtained in the step S014 as a main component of a soilless or soilless culture nutrient solution for planting and cultivating plants to obtain the selenium-rich plant source obtained in the step S01;
S016 is to dry the plant source obtained in the step S015 and to obtain selenium-rich plant source powder.
compared with the prior art, the main differences of the preparation method of the plant source powder are as follows: firstly, the acquisition modes of selenium are different, the prior selenoprotein powder is generally prepared by directly using yeast selenium as a raw material and then matching auxiliary materials, and the defect is that the yeast selenium has natural peculiar smell and can cause the problem that people can not swallow the selenoprotein, and the selenium-rich soil is used for planting plants, and then the plants are used as selenoprotein raw materials, so that the mode has no peculiar smell, but the selenium content in the soil is very small, and the true selenoprotein content in the finished selenoprotein finished product is low. Secondly, the selenium content is much higher than that of the existing selenoprotein product, and the daily requirement of selenium can be met by quantitatively measuring a small part of organic selenium particles in the selenium-rich selenium. The reason is that the organic selenoprotein in the selenium yeast is hydrolyzed into polypeptide, small peptide and amino acid by protease by using a directional enzyme digestion method, under the condition, the organic selenoprotein can be directly absorbed into plant protein by plants in a cultivation mode, so that the formed plant organic selenoprotein can effectively convert the selenium element in the selenium yeast which is not kept, meanwhile, the possibility that a small part of inorganic selenium in the selenium yeast is harmful to human bodies and even poisoned is avoided, and the safety of selenium products is improved.
Preferably, the drying process in step S016 includes any one of air drying, oven drying or freeze drying. The freeze-drying refers to that the water-containing plant source is directly placed at the temperature of the eutectic point or below, the dehydration of the plant source is realized through a direct sublimation mode, so that only physical reaction occurs in the whole dehydration process, no chemical reaction exists, the nutrient components in the plant source can be retained to the maximum extent, the plant source has better integrity compared with the traditional drying, sun-drying and air-drying processes, the natural color and the shape of the plant source can be completely retained, and partial loss of the nutrient components cannot be caused in the drying process.
further preferably, the step of obtaining the mixture M in step S02 is as follows:
S021, placing the raw material powder and the auxiliary material powder into a three-dimensional mixer to be mixed, wherein the three-dimensional mixer is at least one of horizontal, longitudinal, tangential, radial, transverse rolling and longitudinal rolling, and the movement period or the consumed time unit of any movement direction is not less than 2000. The motion cycle mentioned here refers to a motion track unit when the circular motion completes one motion track unit or a track unit used as the irregular motion repeat action, that is, after the same component starts to move at any starting point, the whole track returning to the starting point after passing through a complete motion track is marked as a motion cycle. The elapsed time unit is the time required for the particles to be able to perform the maximum distance displacement in the effective mixing space under the driving force of the mixer, with a single linear movement. That is, in order to ensure sufficient mixing, the mixer used must have at least three spatial motion mixed modes in which single-cycle motions are combined together, and the number of times of repetition of any one single-cycle motion is not less than 2000.
s022, after the step S021 is completed, contacting water in a mist form with the raw material and auxiliary material mixture in a moving state, and repeating the step S021 until the number of cycles or consumed time units in any moving direction is not less than 5000. The number of times or period of cumulative mixing is not less than 5000 times or more. When the mixing degree is actually controlled, calculation is carried out according to time, the time of each period is set as T, the time required by step S021 is T1, the time required by the whole period is T2, T1 is 2000T, T2 is 5000T, T is determined by the rotating speed or speed grade set by the equipment, and can be known through intrinsic parameters of the equipment, so that the mixing uniformity degree can be controlled by controlling only one time factor in the actual operation process.
preferably, the linear motion driving manner of horizontal, longitudinal, tangential and radial in the step S021 adopts circulating high-pressure airflow mixing. The existing stirring is mostly carried out by using a physical stirring device, or by using a stirring rod, or by using a stirring blade. The raw materials of stirring in this application are the very little powdered of particle diameter, consequently, adopt gas to blow the stirring, and adopt the not equidirectional mixing turbulence to stir, can be in the very short time for various powders can realize very big mixture, and its even degree and time cycle are incomparable for current physics stirring mode. The uniform degree of stirring can directly determine the precision of quantitative measurement of subsequent finished products. Since the intake of selenium is calculated according to the product of the quality and the content of the finished product, the uniformity plays an important role in the subsequent calculation.
the invention also provides an antioxidant plant source high organic selenium particle which is prepared by the method, and the antioxidant plant source high organic selenium particle comprises a selenium-rich plant source, maltodextrin, soluble starch and edible calcium carbonate, wherein the content of selenium protein is 2000 mg/kg.

Detailed Description
For convenience of understanding, the following terms or nouns referred to in this application are explained as follows:
plant-derived high organic selenium particles: the granular product is prepared by using edible plants with high organic selenium enrichment capacity and content as main natural selenium sources and adding or not adding other food raw materials or food additives through drying, crushing and other related food processing technologies.
Example 1:
Referring to the attached figure 1 of the specification, the preparation method of the antioxidant plant source high organic selenium particle comprises the following steps:
S01, respectively weighing the raw materials, the auxiliary materials and the solvent for granulation for later use; the auxiliary materials comprise edible calcium carbonate, maltodextrin and soluble starch, the solvent is water, and the raw materials are selenium-rich plant source powder;
S02, uniformly mixing the raw materials, the auxiliary materials and the solvent in the S01 to obtain a mixture M;
s03, putting the mixture M into a rotary granulator for rotary granulation to obtain particles P;
s04, placing the particles P into a spherical shot blasting machine for shot blasting to obtain spherical particles G;
S05, placing the spherical particles G into a fluidized bed for boiling and drying to obtain the finished product of the high organic selenium particles.
as a preferred embodiment of the present invention, in order to further improve the oxidation resistance of the selenium element in this embodiment, the step S05 further includes a coating process, since after the granulation and shot blasting, the organic selenium particles may be oxidized only on the surface of the spherical body of the particles by contacting with air, which improves the oxidation resistance by several times compared with the existing powder under the same condition; however, the surface of the spherical particle has no oxidation resistance, and in order to solve the problems of oxidation resistance and moisture on the surface, a coating and film-making process is particularly added to realize the comprehensive oxidation resistance of the spherical particle.
it is worth to be noted that the problem of oxidation resistance of the current finished selenoprotein is easily ignored by people, therefore, most of the current finished selenoprotein exists in a powder form, and therefore, in real life, since selenium supplement is a very long process, the selenium supplement must be taken daily according to the amount, and repeated bottle opening is carried out for a long time, inedible selenoprotein can be sufficiently contacted with air to cause oxidation, so that part, even most of effective components become ineffective components, and the proportion of the ineffective components occupying the selenoprotein components can be calculated by the following formula:
the weight ratio of the failure components is 4 pi r2h rho/(4/3) pi r3 rho
Wherein h represents the oxidized thickness of the selenoprotein powder in the exposure period, rho represents the density of the selenoprotein, and r is the particle size;
The weight ratio of the ineffective components can be visually indicated by the illustration shown in fig. 1, wherein the shaded part of the circular ring is the oxidized part, and the white part inside is the non-oxidized part.
from the above formula, we can study each selenoprotein powder particle as a sphere, and when the oxidized thickness h of selenoprotein in the whole oxidation period is larger than the particle diameter radius r, the oxidation ratio is 100%, that is, all the rest of the uneaten selenoprotein powder is oxidized. The oxidized thickness h is positively correlated with the oxygen concentration and the oxidation contact time, the oxygen concentration in the air is basically an average value, the error of the oxygen content in the air in different urban areas is small, the oxidation contact time is the main influence factor, however, the oxidation speed of the same selenium protein powder is the same, and the oxidized thickness h is larger as long as the oxidation time is longer. On the premise of not taking any protective measures, the smaller the proportion of the selenium protein to be oxidized is, the larger the particle size r of the selenoprotein powder is, so that the longer the time period for the oxidized thickness h to reach the value of r is, the lower the proportion of the ineffective components in unit time is, and the less the effective selenium element is ineffective.
example 2:
This example is a film coating which is based on example 1, and is capable of further reducing the oxidation of selenoprotein particles, further refining the coating process, ensuring the strong oxidation resistance and moisture resistance of the organoselenium particles, and ensuring the thickness of the coating to be controlled within 0.1 mm. The method is realized by adopting the following scheme.
S051 preparing a coating film-forming material: mixing hydroxypropyl methyl cellulose and triethyl citrate with the mass ratio of 0.68-0.72:1, and placing the mixture into a coating spray gun cavity of a granulating and coating machine;
s052 controlling the environmental parameters of the spherical particles G for high-speed fluidization in the fluidized bed pot of the granulating and coating machine as follows: the air inlet temperature is controlled at 48-55 ℃, and the boiling drying time is 20 min;
s053 under the premise of ensuring that the step S052 is uninterrupted, spraying the film-forming material in the step S051 in a mist shape, carrying out surface contact with the dried spherical particles G, and fixing the film to form a film, so as to form a coating film on the surfaces of the spherical particles G, wherein the thickness of the coating film is controlled to be 0.05mm-0.1 mm. The thickness of the coating film is controlled to be 0.05-0.1mm, the method can be realized, the process method can realize ultrathin coating by a spray contact mode, but the actual thickness is calculated by the weight of the film-forming material according to the following actually required coating amount, and the calculation formula is as follows: the spraying weight of the film-forming material is 0.03-5 of the total weight of the organic selenium particles.
The coating used and the method for coating the selenoprotein particles in the present embodiment are different from the existing coating, the purpose of the coating in the present application is to prevent the selenoprotein particles from being exposed to air and generating contact oxidation with oxygen in the air to cause selenium supplement failure, and the coating is arranged for shielding the taste or smell of the medicine compared with the existing coating, so the coating in the present application must be thin, and uniform film formation on the surface of the selenoprotein particles is required, and the purpose of ensuring air isolation and independent flowability of the particles is ensured. The technical points of the coating in the application, which is different from the existing coating, mainly lie in that: first, the particle is subjected to the fluid-bed drying and coating processes in the same equipment but at different times, and the time of contact mixing of the coating film-forming material and the particles is closely controlled. The coating film-forming material can be sprayed out only after the granules are boiled and dried for 20 minutes, and the granules are in a fog form, and the granules are naturally contacted with the existing coating and then repeatedly rolled and adhered to each other to form a polysaccharide type coating which is completely different. Since the content of the plant-derived selenium in the selenoprotein particles is verified according to the standard of the reference intake of dietary nutrients of the residents in China WS/T578.3-2017 before the particles are prepared, otherwise, excessive intake of the selenium can cause negative effects and even harm to the body, and therefore, the content is very important for trace element supplements, and the effect of the selenium is not negligible for tens of millions.
The reference intake of dietary trace elements of Chinese residents is as follows:

After the particles are dried for 20 minutes by boiling, no matter which material is adopted by the plant source powder, for example, the most common carriers comprise bean sprouts, kidney beans, broccoli and the like, after the particles are dried for 20 minutes by boiling at the temperature of about 50 ℃, the natural flowability of the particles is very good, at the moment, the coating film forming material is sprayed in a mist spraying mode to be contacted with the selenoprotein particles which move irregularly at high speed, the selenoprotein particles can be absorbed at the moment of contact and can quickly form a coating film under the action of drying airflow flowing at high speed, compared with the existing coating process, the process has very large difference in the uniformity degree and the thickness of the coating film, the coating film with the thickness of less than 0.1mm is difficult to form the finished coating film by adopting the existing coating process, the problems of film leakage and incomplete can occur, and the coated particles are larger, this is very noticeable as the larger the area of the exposed drain membrane.

S05, placing the spherical particles G into a fluidized bed for boiling and drying to obtain the finished product of the high organic selenium particles.
compared with the prior art, the main differences of the preparation method of the plant source powder are as follows: firstly, the selenium element is obtained in different manners, the existing selenium protein powder is generally prepared by directly using yeast selenium as a raw material and then matching auxiliary materials, and the defect that the yeast selenium has natural peculiar smell and can cause the problem that people cannot swallow the selenium protein powder is that selenium-rich soil is used for planting plants, wherein the plant variety is kidney beans. Then the plant is used as the selenoprotein raw material, no peculiar smell exists in the mode, but the selenium content in the soil is very small, so that the true selenoprotein content in the finished selenoprotein finished product is low. Secondly, the selenium content is much higher than that of the existing selenoprotein product, and the daily requirement of selenium can be met by quantitatively measuring a small part of organic selenium particles in the selenium-rich selenium.

in this embodiment, the drying process in step S016 includes any one of air drying, oven drying or freeze drying. The freeze-drying refers to that the water-containing plant source is directly placed at the temperature of the eutectic point or below, the dehydration of the plant source is realized through a direct sublimation mode, so that only physical reaction occurs in the whole dehydration process, no chemical reaction exists, the nutrient components in the plant source can be retained to the maximum extent, the plant source has better integrity compared with the traditional drying, sun-drying and air-drying processes, the natural color and the shape of the plant source can be completely retained, and partial loss of the nutrient components cannot be caused in the drying process.
example 4:
In this embodiment, the step of obtaining the mixture M in step S02 is detailed as follows on the basis of any one of embodiments 1 to 3, and is shown in fig. 2:
s021, placing the raw material powder and the auxiliary material powder into a three-dimensional mixer to perform any three motion mixing including at least horizontal motion, longitudinal motion, tangential motion, radial motion, transverse rolling motion or longitudinal rolling motion; the auxiliary material powder comprises a mixture of beta-cyclodextrin and microcrystalline cellulose with the mass part of not more than 5%. As shown in the figure, the reciprocating motion of the composite spiral ascending motion with the self-rotation effect from bottom to top, falling back under the action of gravity after reaching the top and ascending is formed, so that the motion tracks of all particles are completely different, and the uniformity of mixing is ensured. And the movement period or the consumed time unit of any movement direction is not less than 2000. The motion cycle mentioned here refers to a motion track unit when the circular motion completes one motion track unit or a track unit used as the irregular motion repeat action, that is, after the same component starts to move at any starting point, the whole track returning to the starting point after passing through a complete motion track is marked as a motion cycle. The elapsed time unit is the time required for the particles to be able to perform the maximum distance displacement in the effective mixing space under the driving force of the mixer, with a single linear movement. That is, in order to ensure sufficient mixing, the mixer used must have at least three spatial motion mixed modes in which single-cycle motions are combined together, and the number of times of repetition of any one single-cycle motion is not less than 2000.
S022, after the step S021 is completed, contacting water in a mist form with the raw material and auxiliary material mixture in a moving state, and repeating the step S021 until the number of cycles or consumed time units in any moving direction is not less than 5000. The number of times or period of cumulative mixing is not less than 5000 times or more. When the mixing degree is actually controlled, calculation is carried out according to time, the time of each period is set as T, the time required by step S021 is T1, the time required by the whole period is T2, T1 is 2000T, T2 is 5000T, T is determined by the rotating speed or speed grade set by the equipment, and can be known through intrinsic parameters of the equipment, so that the mixing uniformity degree can be controlled by controlling only one time factor in the actual operation process.
In this embodiment, the driving manner of the horizontal and longitudinal linear motions in the step S021 adopts a circular high-pressure airflow mixing manner, and a circumferential driving direction in a tangential direction is added, as shown in fig. 2. The existing stirring methods for such mixing are mostly performed by using a physical stirring device, or by using a stirring rod, or by using a stirring blade. The raw materials of stirring in this application are the very little powdered of particle diameter, consequently, adopt gas to blow the stirring, and adopt the not equidirectional mixing turbulence to stir, can be in the very short time for various powders can realize very big mixture, and its even degree and time cycle are incomparable for current physics stirring mode. The uniform degree of stirring can directly determine the precision of quantitative measurement of subsequent finished products. Since the intake of selenium is calculated according to the product of the quality and the content of the finished product, the uniformity plays an important role in the subsequent calculation.
