Description

Technical Field

[0001] The invention relates to the technical field of nutritional supplement preparation, and in particular to a method for producing ferrous fumarate-embedded particles. Background Art

[0002] Ferrous fumarate is an iron supplement for humans. It has a natural blood-tonifying effect and prevents the occurrence of iron-deficiency anemia. Due to the small amount of ferrous fumarate added, it is generally ultrafinely ground to ensure uniformity when used. However, the following problems may occur during processing: (1) Due to the large difference in particle size after ultrafine grinding, it is difficult to mix evenly, and separation is likely to occur during processing, resulting in uneven dispersion; (2) The powder has poor fluidity, which affects production efficiency.

[0003] In addition, iron supplements have mild gastrointestinal reactions when they are nutritionally fortified. Taking them after meals may reduce gastrointestinal reactions and be easier to tolerate.

[0004] In summary, when ferrous fumarate is added to fortify iron, problems such as mixing uniformity, processing compliance and gastrointestinal reactions are encountered; therefore, there is an urgent need for a method for producing ferrous fumarate particles that has a simple preparation process and does not cause gastrointestinal reactions. Summary of the invention

[0005] The present invention provides a method for producing embedded ferrous fumarate particles, which solves the problems of mixing uniformity, processing compliance and gastrointestinal reactions faced by the prior art in the processing of ferrous fumarate. The embedded ferrous fumarate particles prepared by liquid dispersion molding do not need to go through a separate granulation process, and have the advantages of uniform particle size, good fluidity, and no gastrointestinal reactions. In order to solve the above technical problems, the technical solution of the present invention is: A method for producing embedded ferrous fumarate particles comprises the following steps: (1) taking hydrogenated vegetable oil, heating it to 75-90° C. to melt it, adding ultrafinely crushed ferrous fumarate into the melted hydrogenated vegetable oil under stirring conditions, dispersing it, and keeping the temperature and stirring for 10-20 minutes; (2) The ferrous fumarate particles are distributed onto a drying plate in turn to solidify naturally, crushed, and sieved to obtain the ferrous fumarate embedded particles.

[0006] Wherein, the mass ratio of the ultrafinely crushed ferrous fumarate to hydrogenated vegetable oil is 1: (0.8-0.9).

[0007] Wherein, in step (1), the stirring time is 10 to 20 minutes.

[0008] Wherein, in step (2), the solidification molding method is to spread the evenly stirred mixture evenly on a suitable material tray and cool it naturally.

[0009] Wherein, in step (2), after solidification, the solidified material is crushed by a universal crusher or a hammer crusher with a cooling function.

[0010] Wherein, the pulverizer is equipped with a 40-100 mesh basket.

[0011] Wherein, in step (2), the sieving is performed using an oscillating sieve, and the oscillating sieve is equipped with a 40-120 mesh screen.

[0012] Wherein, in step (1), sodium dodecyl sulfate is also added, and the amount of sodium dodecyl sulfate added is 0.05-0.1 of the mass of ferrous fumarate.

[0013] The present invention makes full use of the low melting point of hydrogenated vegetable oil, is easy to operate under normal pressure, and naturally solidifies into a solid at room temperature. Ultrafinely crushed ferrous fumarate is creatively added to molten hydrogenated vegetable oil for full dispersion, and solidified into a solid after cooling. In order to prevent the excessive increase in the temperature of the crushing chamber due to the long crushing time in large-scale production, a universal crusher or a hammer crusher with a cooling function is used for crushing. The outer layer of the crushed ferrous fumarate is wrapped by the hydrogenated vegetable oil to achieve an embedding effect. In order to ensure that the ferrous fumarate particles are used in different scenarios, crushing screens and screening screens with different mesh sizes can be flexibly selected.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: The production method of the embedded ferrous fumarate particles of the present invention is different from the traditional granulation method using granulation equipment. It uses a liquid dispersion molding method and does not need to go through a separate granulation process. The preparation process is simple, and the prepared embedded ferrous fumarate particles have the advantages of uniform particle size, good fluidity, and no gastrointestinal reaction, thereby improving the mixing uniformity with the base material and improving the production efficiency.

[0029] Wherein, in step (2), the pulverizer is equipped with a 40-mesh basket, and the sieving is performed using an oscillating sieve equipped with a 40-mesh screen. Example 5

[0030] This embodiment provides a method for producing embedded ferrous fumarate particles, comprising the following steps: (1) Take hydrogenated vegetable oil, heat it to 85°C to melt it, stir it for 15 minutes, add sodium dodecyl sulfate to the melted hydrogenated vegetable oil for dispersion, then add ultrafinely crushed ferrous fumarate to the melted hydrogenated vegetable oil for dispersion, and keep it warm and stir for 15 minutes; the mass ratio of the ultrafinely crushed ferrous fumarate to the hydrogenated vegetable oil is 1:0.85, and the mass ratio of sodium dodecyl sulfate to ferrous fumarate is 1:0.1.

[0031] (2) The stirred mixture is spread evenly on the material tray, cooled naturally, crushed by a universal grinder or hammer grinder with cooling function, and then sieved to obtain embedded ferrous fumarate particles with an angle of repose of 31°. The product picture is as follows Figure 1 shown.

[0032] Wherein, in step (2), the pulverizer is equipped with a 40-mesh basket, and the sieving is performed using an oscillating sieve equipped with a 40-mesh screen.

[0033] Comparative Example 1: Lowering the melting temperature of hydrogenated vegetable oil Heat the hydrogenated vegetable oil to 70°C to melt it, add the ultrafinely crushed ferrous fumarate into the molten hydrogenated vegetable oil under stirring and disperse it, keep it warm and stir for 10 to 20 minutes; then distribute it to the drying plate in turn to solidify naturally, grind it with a universal grinder equipped with a 60-mesh basket with cooling function, and pass it through a 60-mesh oscillating sieve to obtain embedded ferrous fumarate particles; the particles have white spots and red spots on the surface, indicating that the ferrous fumarate is not evenly dispersed.

[0034] From the comparison between Example 1 and Comparative Example 1, it can be seen that: when the melting temperature of the hydrogenated vegetable oil is lowered, the hydrogenated vegetable oil is not completely melted and the ferrous fumarate is not evenly dispersed.

[0035] From the comparison of Example 1, it can be seen that as the number of crushing and screening meshes increases, the fluidity of the obtained embedded ferrous fumarate particles becomes worse.

[0036] As a preferred embodiment of the present invention, sodium dodecyl sulfate is added. Since sodium dodecyl sulfate contains lipophilic long-chain alkyl, it is beneficial for ferrous fumarate to be dispersed in the molten hydrogenated vegetable oil. After adding sodium dodecyl sulfate, the fluidity of the particles becomes better. In addition, sodium dodecyl sulfate contains hydrophilic sodium sulfonate, which is beneficial for the release of ferrous fumarate in the stomach and intestines.

[0037] Comparative Example 2: Turn off cooling water in the crusher Heat the hydrogenated vegetable oil to 75-90°C to melt it, disperse the ultrafinely crushed ferrous fumarate in the melted hydrogenated vegetable oil under stirring, and keep it warm and stir for 15 minutes; then distribute it to the drying plate in turn to solidify naturally, grind it with a universal grinder equipped with a 60-mesh basket (turn off the cooling water), and pass it through a 60-mesh oscillating sieve to obtain embedded ferrous fumarate particles; after continuous grinding for 30 minutes, it was found that the discharge was slow, and the grinding chamber was stopped and opened, and it was found that the screen was sticky and the color of the particles was different.

[0038] From the comparison between Example 1 and Comparative Example 2, it can be seen that: without cooling function during pulverization, the temperature of the pulverization chamber is prone to rise, the hydrogenated vegetable oil will partially melt and block the screen, the color of the particles will differ, and the production efficiency will slow down.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiment, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiment or to replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
