Through multiple groups of stirring devices in different directions, the stirring efficiency can be improved, and the preparation time can be saved. The feeding box is used to store auxiliary materials, and the time control switch can be timed. After the time is up, the electric telescopic rod lifts the baffle, and then the auxiliary materials in the feeding box are put into the chassis on time. Manual feeding is no longer required, saving time and effort.

[0004] Chinese patent application number CN202320830823.1 discloses a modulation device for food additives for food production, including a modulation box, a chute is provided on the inner bottom wall of the modulation box, a slider is movably connected to the inner wall of the chute, a modulation frame is fixedly connected to the top of the slider, a plate groove is provided on the top of the modulation box, and a mounting plate is movably connected to the inner wall of the plate groove.

[0005] The above solution may cause the following problems during use:

[0006] Powdery food additive raw materials are generally sealed in vacuum packaging bags. Most of the powdery food additive raw materials are in powder or block form. After a long time of vacuum packaging, the powdery raw materials will also caking. At this time, it is necessary to crush and grind the caked raw materials to ensure uniform mixing of the raw materials and make the target powdery food additive. However, the above solution does not have the effect of grinding and cannot ensure uniform mixing of the caked raw materials.

[0007] When preparing food additives, there are also cases where powdery and liquid raw materials are mixed together. After these two raw materials are added to the mixing device and stirred, water vapor will appear in the liquid. The water vapor will adhere to the position where the materials are put in, causing the powdery raw materials in the bin to get damp and affecting the falling of the powdery raw materials.

[0008] When preparing different food additives, the proportioning of the raw material components is very important. Different amounts of the put-in materials will result in different tastes of the prepared food additives. Therefore, it is necessary to strictly control the proportion of the amounts of the food additive raw materials put in and mixed. However, the above solution cannot weigh and quantitatively put in the raw materials, and can only achieve the proportioning by weighing the raw materials one by one through external existing devices, and the operation steps are relatively complex.

[0018] A method for modulating a food additive, according to the above-mentioned food additive modulating device, includes the following steps:

[0019] S1: Through the feed port, control the mixing motor to drive the turntable to rotate, place the additive raw materials one by one in the material bin, close the feed port after completion, and start the driving motor to work. The driving motor drives the transmission rod to start rotating;

[0020] S2: The spiral blade rotates to feed the material to the lower end of the material bin, send the material and the caked material to the grinding disc. The ground material is inside the material bin. The material enters between the grinding lower disc and the grinding rotating disc through the blanking hole, impacts and breaks the material and rotates for grinding to crush the material again;

[0021] S3: The material ground by the grinding lower disc and the grinding rotating disc falls onto the fixed ring, and the V-shaped plate is used to scrape and collect the material, and it is evenly scattered into the mixing tank body through the material pipe. In cooperation with the weighing sensor, the material in the material bin is weighed in real time. When the discharged material is consistent with the set material, the driving motor stops working;

[0022] S4: After the V-shaped plate leaves, the material pipe will move upward and impact the grinding rotating disc, prompting the material on the grinding rotating disc to fall to the upper end of the fixed ring;

[0023] S5: After the material falls into the mixing tank body, it is mixed with the powder material by the rotation of the stirring blade. After the liquid material enters the mixing tank body, the floating plate floats up to cooperate with the stirring blade and the stirring wheel to stir and mix the material. The mixed material will be discharged through the discharge pipe.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The raw materials are conveyed downward by the spiral blade to the edge of the grinding disc, and the spiral blade continuously conveys the raw materials. Therefore, the raw materials at the back will squeeze the raw materials in front toward the grinding disc through the action of the spiral blade. In cooperation with the inner wall of the material bin, the agglomerated raw materials are squeezed by the grinding disc to crush and grind the agglomerated raw materials, and the agglomerated raw materials are preliminarily crushed and ground. At the same time, the rotation of the transmission rod drives the grinding rotating disc to rotate. The top block on the upper end of the grinding rotating disc cooperates with the trapezoidal groove on the grinding pressure disc. After the grinding pressure disc is lifted, the spring on the grinding pressure disc is compressed. When the top block coincides with the trapezoidal groove, the spring pushes the grinding pressure disc to hit the grinding rotating disc. After the grinding pressure disc and the grinding rotating disc rotate a certain angle, they are lifted again, which is convenient for impacting and crushing the raw materials and rotating and grinding them, turning the agglomerated raw materials into powder.

[0026] 2. The raw materials ground by the grinding pressure disc and the grinding rotating disc fall onto the fixed ring, and the V-shaped plate scrapes and collects the raw materials, and the collected raw materials are introduced into the material pipe. The V-shaped plate presses down on the material pipe. After the material pipe is pressed down, the cover is opened through the connecting rod. The raw materials in the material pipe will be discharged into the interior of the mixing tank body at this time, and in cooperation with the rotation of the turntable, the raw materials are evenly scattered into the mixing tank body. After the V-shaped plate leaves, the material pipe will move upward and impact the grinding rotating disc, prompting the raw materials on the grinding rotating disc to fall onto the upper end of the fixed ring. At the same time, after the material pipe moves upward, multiple covers quickly return to their original positions to prevent the water vapor of the liquid raw materials inside the mixing tank body from entering the powdered raw materials and causing the powdered raw materials to become damp.

[0027] 3. Through the rotation of the turntable, the raw materials are evenly scattered into the mixing tank body. At the same time, the raw materials in the material bin are weighed in real time through cooperation with the weighing sensor. When the weight of the discharged raw materials is consistent with the set raw materials, the drive motor stops working, ensuring that the weight of the raw materials can be quantitatively put in and ensuring the modulation of food additives.

[0051] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0052] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, powdered food additive raw materials are generally sealed in vacuum packaging bags. Most powdered food additive raw materials are in powder or block form. After a long time of vacuum packaging, the powdered raw materials will also agglomerate. At this time, the agglomerated raw materials need to be crushed and ground to ensure uniform mixing of the raw materials and produce the target powdered food additive. A food additive modulation device and modulation method, including a mixing tank body 1. A turntable 15 is rotatably connected inside the mixing tank body 1. A central rod 111 is fixed on the turntable 15. A plurality of weighing sensors 151 are fixed along the circumference of the upper end of the turntable 15. By rotating the turntable 15, the raw materials are evenly scattered into the mixing tank body 1. At the same time, the raw materials in the material bin 2 are weighed in real time through cooperation with the weighing sensors 151. When the weight of the discharged raw materials is consistent with the set raw materials, the drive motor 211 stops working, ensuring that the weight of the raw materials can be quantitatively put in, guaranteeing the modulation of food additives. The materials are in the material bin 2 and are discharged from the material bin 2. The weighing sensors 151 weigh the materials before and after discharge respectively, and the difference between the two is used to obtain the weight of the discharged materials, realizing quantitative feeding,At the upper ends of the load cells 151, there are material bins 2 provided. At the upper ends of the material bins 2, mounting frames 21 are installed. At the upper ends of the mounting frames 21, drive motors 211 are fixed. The output ends of the drive motors 211 are in transmission connection with transmission rods 212. On the transmission rods 212, spiral blades 22, grinding discs 23, wind blades 25 and scraping rods 24 are fixedly connected in sequence from top to bottom. By the cooperation of the grinding discs 23 and the inner walls of the material bins 2, the caked raw materials are extruded, so that the caked raw materials are crushed and ground, and the caked raw materials are preliminarily crushed and ground. The scraping rods 24 are in contact with the inner walls of the material bins 2. At the lower ends of the scraping rods 24, there are cross bars 241 facing the transmission rods 212. After the raw materials entering the interior of the material bins 2 are first ground and crushed by the grinding discs 23, they come to the lower part of the grinding discs 23. At the same time, the transmission rods 212 drive the wind blades 25 and the scraping rods 24 to rotate. The conveying wind blades 25 generate wind to blow the raw materials up in the interior of the material bins 2, so that the raw materials are blown and circulated in the interior of the material bins 2. And by the contact of the scraping rods 24 with the inner walls of the material bins 2, the raw materials are agitated to prevent the raw materials from piling up. At the same time, the raw materials attached to the inner walls of the material bins 2 are scraped off. At the lower ends of the transmission rods 212, there are grinding pressing discs 3 slidably connected. At the lower ends of the grinding pressing discs 3, there are grinding rotating discs 4 fixedly connected to the transmission rods 212. The grinding pressing discs 3 and the grinding rotating discs 4 cooperate to perform secondary crushing and grinding on the raw materials, grinding the raw materials into powder, which is convenient for subsequent mixing and blending of the raw materials. At the lower ends of the grinding rotating discs 4, there are V-shaped plates 41 fixed. The V-shaped plates 41 are used to collect the crushed and ground raw materials, scrape the raw materials to the center and scrape them into the material pipes 6. At the lower ends of the V-shaped plates 41, there are fixed rings 5 fixedly connected to the turntables 15. A plurality of material pipes 6 are slidably connected to the fixed rings 5. The lower ends of the material pipes 6 are connected with a plurality of sealing caps 66 arranged in a ring. The sealing caps 66 are rotatably connected to the fixed rings 5. The sealing caps 66 are used to seal the material pipes 6 to prevent the material pipes 6 from being in a communicating state all the time, resulting in water vapor entering the material pipes 6.,

[0053] Please refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8, to prepare different food additives, the ratio of raw material ingredients is very important. Different amounts of materials put in will produce different tastes of prepared food additives. Therefore, it is necessary to strictly control the ratio of the mixed food additive raw materials. The above scheme cannot weigh and quantitatively put the raw materials. The raw materials can only be weighed one by one through existing external devices to achieve the ratio. The operation steps are relatively complicated. A plurality of weighing sensors 151 are fixed along the circumference of the upper end of the turntable 15. The processing device outside the weighing sensor 151 cooperates to obtain the weight of the raw materials in the material bin 2, thereby achieving the effect of quantitative discharge of the raw materials in the material bin 2, preventing excessive addition of raw materials, resulting in the prepared additives not meeting the requirements. The upper end of the weighing sensor 151 is provided with a material bin 2, and the material bin 2 is in the shape of a silo. The bin 2 is used to hold raw materials. A mixing motor 11 is fixed to the upper end of the mixing tank body 1. The output end of the mixing motor 11 is transmission-connected to the center rod 111. A feed port 13 is provided at the upper end of the mixing tank body 1. The feed port 13 corresponds to the material bin 2. A discharge pipe 12 is connected to the lower end of the mixing tank body 1. A valve is provided on the discharge pipe 12. A plurality of legs 14 are fixed along the circumference of the outer wall of the mixing tank body 1. The legs 14 are installed on an existing platform. The mixing motor 11 is an existing equipment. The mixing motor 11 provides power to rotate the center rod 111 and cooperates with other components to mix the raw materials inside the mixing tank body 1. The feed port 13 is used to place the raw materials into the material bin 2, and the legs 14 are used to fix the mixing tank body 1.

[0054] See also Figure 1 , Figure 2 , Figure 10 and Figure 11, considering that when mixing powdered raw materials, the raw materials will be lifted up, but the raw materials will still gather at the bottom, resulting in uneven mixing of the powdered raw materials. When the raw materials are liquid, a vortex will appear when the liquid is stirred during mixing, causing the liquid to rotate, affecting the mixing effect. A fixing frame 16 is fixed inside the mixing tank body 1, and the center rod 111 is rotatably connected to the fixing frame 16. The fixing frame 16 is used to limit the center rod 111 to prevent swinging and shaking after the center rod 111 rotates. Two symmetrically arranged mixing blades 17 are fixed on the center rod 111. The two mixing blades 17 are located at the upper and lower ends of the fixing frame 16. The center rod 111 drives the two mixing blades 17 to rotate, and the two mixing blades 17 blow air relative to each other. When the mixing tank body When there is powder inside, the wind force generated by the two mixing blades 17 drives the powder to move toward each other and mix, and at the same time, the stirring blade 181 rotates to make the powder mixed more evenly. The opposite sides of the two mixing blades 17 are provided with floating plates 18 that are slidably connected to the central rod 111, and the upper ends of the floating plates 18 are provided with stirring blades 181 that are slidably and transmission-connected to the central rod 111. The stirring blades 181 are in a cross shape, and a stirring wheel 19 is fixed at the lower end of the central rod 111. A plurality of trapezoidal rods 191 are fixed inside the stirring wheel 19 along its circumference. The trapezoidal rods 191 are convenient for lifting the powdered raw materials upward. After the liquid material enters the mixing tank body 1, the floating plate 18 floats up and will rise against the stirring blade 181, and at the same time, the stirring blade 181 and the stirring wheel 19 are coordinated to stir and mix the materials.

[0055] See also Figure 3 , Figure 4 , Figure 5 and Figure 6, considering that after the powdery raw materials are placed in the material bin 2, it is necessary to convey the raw materials to the bottom of the material bin 2 for quantitative discharge, and at the same time prevent the raw materials from adsorbing on the inner wall of the material bin 2. The diameter of the spiral blade 22 increases sequentially from top to bottom. The outer wall of the grinding disc 23 is in the shape of a slope. The upper end of the grinding disc 23 gradually protrudes from the outside to the inside, and the height of the protrusion gradually increases. The spiral blade 22 conveys the raw materials downward, conveys the agglomerated raw materials to the edge of the grinding disc 23, and the spiral blade 22 continuously conveys the raw materials. Therefore, the raw materials at the back will squeeze the raw materials in front toward the grinding disc 23 under the action of the spiral blade 22. There is a spacing between the wind blade 25 and the grinding disc 23, which is convenient for the generated wind force to form a circulating flow between them. Symmetrically arranged mounting grooves 152 are provided on the turntable 15. A limiting plate 31 corresponding to the mounting groove 152 is fixed on the outer wall of the grinding and pressing disc 3. The limiting plate 31 is connected to the turntable 15 through a spring. At the same time, the grinding rotating disc 4 is driven to rotate by the rotation of the transmission rod 212. The top block 42 at the upper end of the grinding rotating disc 4 cooperates with the trapezoidal groove 33 on the grinding and pressing disc 3. After the grinding and pressing disc 3 is lifted, the spring on the grinding and pressing disc 3 is compressed. When the top block 42 coincides with the trapezoidal groove 33, the spring pushes the grinding and pressing disc 3 to impact the grinding rotating disc 4. After the grinding and pressing disc 3 and the grinding rotating disc 4 rotate a certain angle, they are lifted again, which is convenient for impact crushing and rotation grinding of the raw materials, turning the agglomerated raw materials into powder. The rotation not only mixes the materials, but also evenly distributes the materials, preventing the materials from being heavy on one side and light on the other side, and can perform weighing more accurately. The impact grinding is an intermittent process, and there will be a stable grinding process after the impact. After the impact, the weighing sensor 151 will show a large fluctuation. When grinding, the value measured by the weighing sensor 151 is stable, and the weighing value is taken as the value in the stable state.

[0056] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9, Considering the crushing and grinding of agglomerated powdery raw materials, it is necessary to impact-crush the massive raw materials and also grind them. A plurality of feeding holes 32 are provided along the circumference at the upper end of the grinding lower platen 3, and a plurality of trapezoidal grooves 33 are provided along the circumference at the lower end of the grinding lower platen 3. The trapezoidal grooves 33 are right trapezoids. The trapezoidal grooves 33 correspond to the top blocks 42 on the grinding rotating disk 4, causing the grinding lower platen 3 to repeatedly rise and fall, squeezing and crushing the raw materials between the grinding lower platen 3 and the grinding rotating disk 4. At the same time, when the grinding lower platen 3 drops, it contacts the grinding rotating disk 4, and the grinding rotating disk 4 rotates. Grinding is carried out through the grinding lower platen 3 and the grinding rotating disk 4. After the grinding rotating disk 4 rotates a certain distance, it lifts the grinding lower platen 3. A plurality of top blocks 42 are fixed along the circumference at the upper end of the grinding rotating disk 4. The top blocks 42 correspond to the trapezoidal grooves 33. The top blocks 42 are right trapezoids. The overall volume of the trapezoidal grooves 33 is larger than that of the top blocks 42 to achieve the effect of extrusion grinding. A plurality of V-shaped plates 41 are fixed along the circumference at the lower end of the grinding rotating disk 4. The V-shaped plates 41 are used to scrape and collect the crushed raw materials, collecting the raw materials at the bent portion. A plurality of arc-shaped buffer pads 43 are fixed at the lower end of the grinding rotating disk 4. The buffer pads 43 are used to buffer the impact of the material pipe 6, reduce the impact sound between them, and at the same time can cause the grinding rotating disk 4 to vibrate slightly, facilitating the rapid fall of the raw materials on the fixing ring 5. The buffer pads 43 correspond to the material pipe 6 on the fixing ring 5. The width of the buffer pads 43 is larger than the diameter of the material pipe 6. The bent portion of the V-shaped plates 41 corresponds to the material pipe 6. An inclined opening is provided at the upper end of the material pipe 6. The lowest end of the opening is lower than the upper end surface of the fixing ring 5. The opening of the material pipe 6 faces the V-shaped plates 41. When the buffer pads 43 move the collected raw materials to the position of the material pipe 6, due to the opening, the raw materials will enter the interior of the material pipe 6. At the same time, the V-shaped plates 41 will also rotate and press down on the material pipe 6, gradually moving the raw materials collected at the bent portion of the V-shaped plates 41 into the interior of the material pipe 6.

[0057] Please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10, when modulating food additives, powdery and liquid raw materials are also mixed together. After the two raw materials are added to the mixing device and stirred, water vapor will appear in the liquid. The water vapor will adhere to the position where the materials are put in, causing the powdery raw materials in the bin to get damp, affecting the falling of the powdery raw materials. An electromagnet 61 is slidably connected to the outer wall of the material pipe 6. The electromagnet 61 is fixed on the fixed ring 5. A base 64 is fixed on the outer wall of the material pipe 6. One end of a compression spring 62 is fixed to the lower end of the electromagnet 61. The other end of the compression spring 62 is fixedly connected to the base 64. A delay contact sensor 63 fixedly connected to the fixed ring 5 is provided at the upper end of the base 64. The delay contact sensor 63 controls the electromagnet 61 to be energized after the base 64 has left the delay contact sensor 63 for a certain period of time. After the material pipe 6 moves downward, the base 64 leaves the delay contact sensor 63 and is no longer in contact. At this time, the electromagnet 61 is powered off, and at the same time, the compression spring 62 is stretched. At the same time, the base 64 pushes the connecting rod 65 downward, and the connecting rod 65 pushes the cover 66 to rotate, and the materials in the material pipe 6 are discharged. After the V-shaped plate 41 leaves the material pipe 6, at the same time, after the delay contact sensor 63 has elapsed for a certain period of time, the electromagnet 61 is energized to adsorb the base 64, and the material pipe 6 is driven to move upward in cooperation with the restoration of the compression spring 62, so that the material pipe 6 moves upward quickly. The upper end of the material pipe 6 hits the fixed ring 5. A plurality of connecting rods 65 are hinged to the lower end of the base 64 along its circumference. The lower end of the connecting rod 65 is slidably and rotatably connected to the cover 66. The connecting rods 65 correspond to the covers 66 one by one. A plurality of the covers 66 enclose a closed circle. The raw materials after being ground by the grinding lower platen 3 and the grinding rotating disk 4 fall onto the fixed ring 5, and the raw materials are scraped and collected by the V-shaped plate 41, and the collected raw materials are introduced into the material pipe 6. The V-shaped plate 41 presses down on the material pipe 6. After the material pipe 6 is pressed down, the cover 66 is opened through the connecting rod 65. The raw materials in the material pipe 6 will be discharged into the interior of the mixing tank body 1 at this time, and in cooperation with the rotation of the turntable 15, the raw materials are evenly scattered into the mixing tank body 1. After the V-shaped plate 41 leaves, the material pipe 6 will move upward and impact the grinding rotating disk 4, prompting the raw materials on the grinding rotating disk 4 to fall onto the upper end of the fixed ring 5. At the same time, after the material pipe 6 moves upward, a plurality of covers 66 quickly recover, preventing the water vapor of the liquid raw materials inside the mixing tank body 1 from entering the powdery raw materials and causing the powdery raw materials to get damp.

[0058] When the present invention is in use:

[0059] First, place the additive raw materials one by one into the material bin 2 through the feed inlet 13, control the mixing motor 11 to drive the turntable 15 to rotate. After completion, close the feed inlet 13, start the drive motor 211 to work. The drive motor 211 drives the transmission rod 212 to start rotating, and the spiral blade 22 rotates to feed the materials towards the lower end of the material bin 2, sending the materials and the caked materials to the grinding disc 23. The grinding disc 23 cooperates with the inner wall of the material bin 2 to extrude and grind the caked materials. The ground materials are circulated and lifted by the air blade 25 in the space inside the material bin 2 and below the grinding disc 23. At the same time, the scraping rod 24 rotates to scrape the materials on the inner wall of the material bin 2 and stir the preliminarily ground materials, facilitating the air blade 25 to lift the materials and preventing the materials from piling up. Also, when encountering liquid materials, the air blade 25 and the scraping rod 24 stir the materials to prevent the components in the liquid materials from precipitating. The materials enter between the grinding lower pressing disc 3 and the grinding rotating disc 4 through the feeding hole 32;

[0060] Then, the transmission rod 212 rotates to drive the grinding rotating disc 4 to rotate. The top block 42 on the upper end of the grinding rotating disc 4 cooperates with the trapezoidal groove 33 on the grinding lower pressing disc 3. After the grinding lower pressing disc 3 is lifted, the spring on the grinding lower pressing disc 3 is compressed. Then, when the top block 42 coincides with the trapezoidal groove 33, the spring pushes the grinding lower pressing disc 3 to impact the grinding rotating disc 4. After the grinding lower pressing disc 3 and the grinding rotating disc 4 rotate a certain angle, they are lifted again, facilitating the impact crushing and rotational grinding of the materials to crush the materials again;

[0061] Next, the materials ground by the grinding lower pressing disc 3 and the grinding rotating disc 4 fall onto the fixed ring 5, and the V-shaped plate 41 scrapes and gathers the materials, introducing the gathered materials into the material pipe 6. The V-shaped plate 41 also presses down on the material pipe 6. After the material pipe 6 is pressed down, the cover 66 is opened through the connecting rod 65. The materials in the material pipe 6 will be discharged into the interior of the mixing tank body 1 at this time, and in cooperation with the rotation of the turntable 15, the materials are evenly scattered into the mixing tank body 1, and in cooperation with the weighing sensor 151, the materials in the material bin 2 are weighed in real time. When the discharged materials are consistent with the set materials, the drive motor 211 stops working. After the V-shaped plate 41 leaves, the material pipe 6 will move upward and impact the grinding rotating disc 4, prompting the materials on the grinding rotating disc 4 to fall onto the upper end of the fixed ring 5;

[0062] Finally, after the materials fall into the mixing tank body 1, the powdery materials are lifted and mixed inside the mixing tank body 1 under the influence of the mixing blades 17 and the stirring wheel 19. At the same time, in cooperation with the rotation of the stirring blade 181, the powdery materials are mixed. After the liquid materials enter the mixing tank body 1, the floating plate 18 floats up and pushes the stirring blade 181 to rise. At the same time, in cooperation with the stirring blade 181 and the stirring wheel 19, the materials are stirred and mixed. The mixed materials will be discharged through the discharge pipe 12.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
