[0002] Food additives are artificial or natural substances added to food to improve the color, aroma, taste and other qualities of food, as well as for the needs of preservation and processing technology. At present, there are 23 categories and more than 2,000 varieties of food additives in my country, which are widely used in various fields of food production. During the preparation process of food additives, various raw materials need to be mixed together and stirred thoroughly.

[0003] Chinese patent application No. CN201921746517.X discloses a rapid preparation device for food additives for food production, which belongs to the field of food production technology, including a chassis, a feed port is opened on one side of the top of the chassis, a first motor is installed in the middle position of the top of the chassis, and the bottom of the first motor is detachably connected to a transmission shaft, the power output end of the first motor is connected to the power input end of the transmission shaft, and the first motor drives the first stirring rod to rotate through the first transmission shaft, and the first stirring rod rotates horizontally, and a roller and a second stirring rod are installed at the bottom of the chassis, and the second stirring rod rotates vertically inside the chassis. 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. The modulation device for food additives for food production, by providing a modulation box, a chute, a slider, a modulation frame, a handle, a connecting rod, a threaded hole, a threaded groove and a sealing door, can take out the modulation frame from the modulation box for cleaning after stirring and modulating the food additive raw materials, so as to avoid the sticky raw materials inside the modulation device from being unable to be cleaned and causing bacterial growth, thereby ensuring the next stirring and modulation work of the food additives, thereby improving the quality of the finished product after the food additives are modulated, and also ensuring the quality of the food after production.

[0005] The above solution may cause the following problems during use: Powdered food additive raw materials are generally sealed in vacuum packaging bags. Powdered food additive raw materials are mostly in powder or block form. After a long period of vacuum packaging, the powdered raw materials will also clump. At this time, it is necessary to crush and grind the agglomerated raw materials to ensure that the raw materials are evenly mixed to make the target powdered food additives. However, the above scheme does not have the grinding effect and cannot ensure that the agglomerated raw materials are evenly mixed.

[0006] When preparing food additives, powdered and liquid raw materials are also mixed together. These two raw materials are added to a mixing device and stirred. During stirring, water vapor will appear in the liquid, and the water vapor will adhere to the position where the materials are added, causing the powdered raw materials in the silo to become damp and affecting the falling of the powdered raw materials.

[0007] When preparing different food additives, the ratio of raw material ingredients is very important. Different amounts of materials added will result in different flavors of the 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 add the raw materials, and the raw materials can only be weighed one by one through existing external devices to achieve the ratio, and the operation steps are relatively complicated.

[0017] A method for preparing food additives, according to the above-mentioned device for preparing food additives, comprises the following steps: S1: Through the feed port, the mixing motor is controlled to drive the turntable to rotate, and the additive raw materials are placed in the material bin one by one. After completion, the feed port is closed, the drive motor is started to work, and the drive motor drives the transmission rod to start rotating; S2: The spiral blade rotates to feed the material to the lower end of the material bin, and the material and the agglomerated material are sent to the grinding disc. The ground material is inside the material bin, and the material enters between the grinding lower pressure plate and the grinding rotating disc through the feeding hole, impacting and crushing the material and rotating and grinding it to crush the material again; S3: The materials ground by the grinding lower pressure plate and the grinding rotating plate fall onto the fixed ring, and are scraped and collected by the V-shaped plate, and evenly scattered into the mixing tank body through the material pipe. The materials in the material bin are weighed in real time in cooperation with the weighing sensor. When the discharged material is consistent with the set material, the drive motor stops working; S4: After the V-shaped plate leaves, the material pipe will move upward and impact the grinding rotating disk, causing the material on the grinding rotating disk to fall to the upper end of the fixed ring; S5: After the material falls into the mixing tank body, the powder material is mixed with the stirring blade. After the liquid material enters the mixing tank body, the floating plate floats up and cooperates with the stirring blade and the stirring wheel to stir and mix the material. After the mixing is completed, the material will be discharged through the discharge pipe.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The raw materials are transported downward by the spiral blades, and the agglomerated raw materials are transported to the edge of the grinding disk. The spiral blades continue to transport the raw materials, so the raw materials at the rear will squeeze the raw materials in front toward the grinding disk through the action of the spiral blades. The grinding disk cooperates with the inner wall of the material bin to squeeze the agglomerated raw materials, so that the agglomerated raw materials are crushed and ground. The agglomerated raw materials are preliminarily crushed and ground. At the same time, the grinding rotating disk is driven to rotate by the rotation of the transmission rod. The top block at the upper end of the grinding rotating disk cooperates with the trapezoidal groove on the grinding lower pressure plate. After the grinding lower pressure plate is lifted up, the spring on the grinding lower pressure plate is compressed. When the top block overlaps with the trapezoidal groove, the spring pushes the grinding lower pressure plate to hit the grinding rotating disk. After the grinding lower pressure plate and the grinding rotating disk rotate at a certain angle, they are lifted up again, which is convenient for impact crushing and rotating grinding of the raw materials, and the agglomerated raw materials are powdered.

[0019] 2. The raw materials ground by the grinding lower pressure plate and the grinding rotating plate fall onto the fixed ring, and are scraped and collected by the V-shaped plate, and the collected raw materials are introduced into the material pipe. The V-shaped plate presses down the material pipe. After the material pipe is pressed down, the cover is opened by 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 with the rotation of the turntable, the raw materials will be evenly scattered into the mixing tank body. After the V-shaped plate leaves, the material pipe will rise and move and impact the grinding rotating plate, causing the raw materials on the grinding rotating plate to fall to the upper end of the fixed ring. At the same time, after the material pipe moves up, multiple covers are quickly restored to prevent the water vapor of the liquid raw materials inside the mixing tank body from entering the powdered raw materials, causing the powdered raw materials to become damp.

[0020] 3. Through the rotation of the turntable, the raw materials are evenly spread 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 delivered and the modulation of food additives can be guaranteed.

After a long period of vacuum packaging, the powdered raw materials will also clump. At this time, it is necessary to crush and grind the agglomerated raw materials to ensure that the raw materials are evenly mixed to make the target powdered food additives. A food additive preparation device and preparation method include a mixing tank body 1, a rotating disk 15 is rotatably connected to the inside of the mixing tank body 1, a center rod 111 is fixed on the rotating disk 15, and the upper end of the rotating disk 15 is fixed along its circumference. There are multiple weighing sensors 151. Through the rotation of the turntable 15, the raw materials are evenly spread into the mixing tank body 1. At the same time, the raw materials in the material bin 2 are weighed in real time through the cooperation with the weighing sensor 151. When the weight of the discharged raw materials is consistent with the set raw materials, the driving motor 211 stops working, ensuring that the weight of the raw materials can be quantitatively added and the modulation of food additives can be ensured. The materials are in the material bin 2 and discharged from the material bin 2. The weighing sensor 151 weighs the materials before and after discharge respectively. The weight of the discharged materials is obtained by subtracting the two to achieve quantitative delivery.The upper end of the weighing sensor 151 is provided with a material bin 2, and the upper end of the material bin 2 is installed with a mounting frame 21, and the upper end of the mounting frame 21 is fixed with a driving motor 211, and the output end of the driving motor 211 is connected to a transmission rod 212, and the transmission rod 212 is fixedly connected with a spiral blade 22, a grinding disc 23, a fan blade 25 and a scraper rod 24 in sequence from top to bottom. The grinding disc 23 cooperates with the inner wall of the material bin 2 to squeeze the agglomerated raw materials, so that the agglomerated raw materials are crushed and ground. The agglomerated raw materials are initially crushed and ground, and the scraper rod 24 is fitted with the inner wall of the material bin 2. The lower end of the scraper rod 24 is provided with a cross bar 241 facing the transmission rod 212. The raw materials entering the material bin 2 are first ground and crushed by the grinding disc 23 and then come to the bottom of the grinding disc 23. At the same time, the transmission rod 212 drives the fan blade 25 and the scraper rod 24 to rotate, and the conveying fan blade 25 generates wind force to blow the raw materials inside the material bin 2 to lift them up, so that the raw materials are blown up and circulated inside the material bin 2, and the raw materials are blown up and circulated through the scraper rod 24 and the material bin 2. 2, stir the raw materials to prevent the raw materials from piling up, and scrape off the raw materials attached to the inner wall of the material bin 2. The lower end of the transmission rod 212 is slidably connected to a grinding lower pressure plate 3, and the lower end of the grinding lower pressure plate 3 is provided with a grinding rotating disk 4 fixedly connected to the transmission rod 212.

The lower end of the grinding rotating disk 4 is fixed with a V-shaped plate 41, and the V-shaped The plate 41 is used to collect the crushed and ground raw materials, scrape the raw materials to the center, and scrape the raw materials into the material pipe 6. The lower end of the V-shaped plate 41 is provided with a fixed ring 5 fixedly connected to the turntable 15. The fixed ring 5 is slidably connected to a plurality of material pipes 6. The lower end of the material pipe 6 is connected to a plurality of annularly arranged covers 66. The covers 66 are rotatably connected to the fixed ring 5. The covers 66 are used to close the material pipe 6 to prevent the material pipe 6 from being in a connected state all the time, causing water vapor to enter the material pipe 6.

[0025] See also 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.

[0026] See also Figure 1 , Figure 2 , Fig.10 and Fig.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.

[0027] See also Figure 3 , Figure 4 , Figure 5 and Figure 6, considering that after the powdered raw materials are placed in the material bin 2, the raw materials need to be transported to the bottom of the material bin 2 and discharged quantitatively, while preventing the raw materials from being adsorbed on the inner wall of the material bin 2, the diameter of the spiral blade 22 increases from top to bottom, the outer wall of the grinding disc 23 is sloped, and the upper end of the grinding disc 23 gradually bulges from the outside to the inside, and the height of the bulge gradually increases. The raw materials are transported downward by the spiral blade 22, and the agglomerated raw materials are transported to the edge of the grinding disc 23. The spiral blade 22 continues to transport the raw materials, so the raw materials at the rear will squeeze the raw materials in front toward the grinding disc 23 through the action of the spiral blade 22. A spacing is provided between the fan blade 25 and the grinding disc 23, so that the generated wind force forms a circulating flow therebetween. The turntable 15 is provided with symmetrically arranged mounting grooves 152, and the outer wall of the grinding lower pressure plate 3 is fixed with a limit plate 31 corresponding to the mounting groove 152.

The top block 42 at the upper end of the grinding rotating disk 4 cooperates with the trapezoidal groove 33 on the grinding lower pressure plate 3. After the grinding lower pressure plate 3 is lifted up, the spring on the grinding lower pressure plate 3 is compressed. When the top block 42 overlaps with the trapezoidal groove 33, the spring pushes the grinding lower pressure plate 3 to hit the grinding rotating disk 4. The grinding lower pressure plate 3 and the grinding rotating disk 4 rotate a certain angle and are lifted up again, which is convenient for impact crushing and rotation grinding of the raw materials, and the agglomerated raw materials are powdered. The rotation not only mixes the materials, but also distributes the materials evenly to prevent the materials from being heavy on one side and light on the other side, so that they can be weighed more accurately. Impact grinding is an intermittent process. There will be a stable grinding process after the impact. After the impact, the weighing sensor 151 will have a large fluctuation. The value measured by the weighing sensor 151 is stable during grinding, and the weighing value is taken as the value in the stable state.

[0028] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9Considering that the agglomerated powdered raw materials need to be crushed and ground, the blocky raw materials need to be impact-crushed and ground at the same time. The upper end of the grinding lower pressing plate 3 is provided with a plurality of feeding holes 32 along its circumference, and the lower end of the grinding lower pressing plate 3 is provided with a plurality of trapezoidal grooves 33 along its circumference. The trapezoidal grooves 33 are right-angled trapezoids. The trapezoidal grooves 33 correspond to the top blocks 42 on the grinding rotating plate 4, so that the grinding lower pressing plate 3 repeatedly rises and falls, and the raw materials between the grinding lower pressing plate 3 and the grinding rotating plate 4 are squeezed. The grinding rotating disk 4 is rotated, and the grinding lower platen 3 and the grinding rotating disk 4 are used for grinding. After the grinding rotating disk 4 rotates a certain distance, the grinding lower platen 3 is lifted up. The upper end of the grinding rotating disk 4 is fixed with a plurality of top blocks 42 along its circumference. The top blocks 42 correspond to the trapezoidal grooves 33. The top blocks 42 are right-angled trapezoids. The overall volume of the trapezoidal grooves 33 is larger than the top blocks 42, so as to achieve the effect of extrusion and grinding. The lower end of the grinding rotating disk 4 is fixed along its circumference. A plurality of V-shaped plates 41 are fixed around the grinding disk 4, and the V-shaped plates 41 are used to scrape and collect the crushed raw materials, and collect the raw materials at the bend. A plurality of arc-shaped buffer pads 43 are fixed at the lower end of the grinding rotating disk 4, and the buffer pads 43 are used to buffer the impact of the material pipe 6 and reduce the impact sound therebetween. At the same time, the grinding rotating disk 4 can vibrate slightly, so that the raw materials on the fixing ring 5 can fall quickly. The buffer pads 43 correspond to the material pipe 6 on the fixing ring 5, and the width of the buffer pads 43 is greater than the width of the material pipe 6. The diameter of the V-shaped plate 41 is corresponding to the material pipe 6. The upper end of the material pipe 6 is provided with an inclined opening. 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 plate 41. When the buffer pad 43 moves the collected raw materials to the material pipe 6, the raw materials will enter the interior of the material pipe 6 due to the opening. At the same time, the V-shaped plate 41 will also rotate to press down the material pipe 6, and gradually move the raw materials collected at the bending part of the V-shaped plate 41 to the interior of the material pipe 6.

[0029] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10When preparing food additives, powdered and liquid raw materials are also mixed together. After the two raw materials are added to the mixing device, they are stirred. During stirring, water vapor will appear in the liquid, and the water vapor will adhere to the position where the materials are put in, so that the powdered raw materials in the silo are damp, which affects the falling of the powdered raw materials. The outer wall of the material pipe 6 is slidably connected with an electromagnet 61, and the electromagnet 61 is fixed on the fixing ring 5. The outer wall of the material pipe 6 is fixed with a base 64, and the lower end of the electromagnet 61 is fixed with one end of a compression spring 62, and the other end of the compression spring 62 is fixedly connected to the base 64. The upper end of the base 64 A delayed contact sensor 63 fixedly connected to the fixing ring 5 is provided. After the base 64 leaves the delayed contact sensor 63 for a certain period of time, the delayed contact sensor 63 controls the electromagnet 61 to be energized. After the material pipe 6 moves downward, the base 64 leaves the delayed contact sensor 63 and is no longer in contact. At this time, the electromagnet 61 is powered off, and the compression spring 62 is stretched. At the same time, the base 64 moves downward against the connecting rod 65, and the connecting rod 65 pushes the sealing cover 66 to rotate, so that the material in the material pipe 6 is discharged. After the V-shaped plate 41 leaves the material pipe 6, the delayed contact sensor 63 energizes the electromagnet 61 after a certain period of time. The base 64 is adsorbed, and the compression spring 62 is restored to drive the material pipe 6 to move up, so that the material pipe 6 moves up quickly, and the upper end of the material pipe 6 hits the fixed ring 5. The lower end of the base 64 is hinged with multiple connecting rods 65 along its circumference. The lower end of the connecting rod 65 is slidably and rotatably connected with the cover 66. The connecting rod 65 corresponds to the cover 66 one by one. The multiple covers 66 form a closed circle. The raw materials ground by the grinding lower pressure plate 3 and the grinding rotating plate 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 and presses down 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 cooperate with the rotation of the turntable 15 to evenly spread the raw materials into the mixing tank body 1. After the V-shaped plate 41 leaves, the material pipe 6 will rise and move and impact the grinding rotating disk 4, causing the raw materials on the grinding rotating disk 4 to fall to the upper end of the fixed ring 5. At the same time, after the material pipe 6 moves up, multiple covers 66 are quickly restored to prevent the water vapor of the liquid raw material inside the mixing tank body 1 from entering the powdered raw material, causing the powdered raw material to become damp.

[0030] When the present invention is used: First, the additive raw materials are placed in the material bin 2 one by one through the feed port 13, and the mixing motor 11 is controlled to drive the turntable 15 to rotate. After completion, the feed port 13 is closed, and the drive motor 211 is started to work. The drive motor 211 drives the transmission rod 212 to start rotating, and the spiral blade 22 rotates to feed the material to the lower end of the material bin 2, and the material and the agglomerated material are sent to the grinding disk 23. The grinding disk 23 cooperates with the inner wall of the material bin 2 to extrude and grind, and the agglomerated material is ground. The ground material is circulated and lifted in the space inside the material bin 2 and the lower end of the grinding disk 23 by the fan blade 25. At the same time, the scraper rod 24 rotates to scrape the material on the inner wall of the material bin 2, and stirs the material after preliminary grinding, so that the fan blade 25 can lift the material to prevent the material from piling up. At the same time, when encountering liquid material, the fan blade 25 and the scraper rod 24 stir the material to prevent the components in the liquid material from precipitating. The material enters between the grinding lower pressure plate 3 and the grinding rotating disk 4 through the discharge hole 32; Then, the transmission rod 212 rotates to drive the grinding rotating disk 4 to rotate, and the top block 42 on the upper end of the grinding rotating disk 4 cooperates with the trapezoidal groove 33 on the grinding lower pressure plate 3. After the grinding lower pressure plate 3 is lifted up, the spring on the grinding lower pressure plate 3 is compressed. Then, when the top block 42 and the trapezoidal groove 33 overlap, the spring pushes the grinding lower pressure plate 3 to hit the grinding rotating disk 4. After the grinding lower pressure plate 3 and the grinding rotating disk 4 rotate at a certain angle, they are lifted up again, which is convenient for impact crushing and rotation grinding of the material, and the material is crushed again; Next, the material ground by the grinding lower pressure plate 3 and the grinding rotating plate 4 falls onto the fixed ring 5, and is scraped and collected by the V-shaped plate 41, and the collected material is introduced into the material pipe 6, and the V-shaped plate 41 presses down the material pipe 6. After the material pipe 6 is pressed down, the cover 66 is opened by the connecting rod 65, and the material in the material pipe 6 is discharged into the interior of the mixing tank body 1 at this time, and cooperates with the rotation of the turntable 15 to evenly spread the material into the mixing tank body 1, and cooperates with the weighing sensor 151 to weigh the material in the material bin 2 in real time. When the discharged material is consistent with the set material, the driving motor 211 stops working. After the V-shaped plate 41 leaves, the material pipe 6 will rise and move and impact the grinding rotating plate 4, causing the material on the grinding rotating plate 4 to fall to the upper end of the fixed ring 5; Finally, after the material falls into the mixing tank body 1, the powdered material will be lifted up and mixed inside the mixing tank body 1 by the influence of the mixing blades 17 and the stirring wheel 19, and at the same time, the powdered material will be mixed by the rotation of the stirring blades 181. After the liquid material enters the mixing tank body 1, the floating plate 18 will float up and lift up against the stirring blades 181, and at the same time, the stirring blades 181 and the stirring wheel 19 will stir and mix the material. After mixing, the material will be discharged through the discharge pipe 12.
