Description

Technical Field

[0001] The present invention relates to the field of food additive production, and specifically to a production process of compound food additives. Background Art

[0002] Compound food additives refer to composite products formed by mixing two or more single food additives (meeting national standards) in a certain proportion, aiming to improve food processing performance, quality or stability through synergistic effects. Compound additives need to be scientifically proportioned to ensure safety and effectiveness and comply with regulatory requirements. Among them, the relatively common one is compound leavening agents, which are special compound additives for food leavening. They generate gases (such as CO2) through chemical reactions, causing the dough or batter to expand when heated, forming a porous structure. They are commonly found in baked foods (cakes, bread) or fried foods (deep-fried dough sticks). However, in the current preparation process of existing compound leavening agents, the mixing degree of raw materials mostly fails to meet the requirements, and there are many phenomena of uneven local mixing, resulting in an imbalance in the acid-base ratio, abnormal gas production, and uneven bubble distribution. This may cause some parts of the baked food to expand and some parts to collapse, or the internal structure to be rough (such as large holes in cakes and uneven thickness of biscuits). Especially when compound leavening agents are prepared in batches in factories, this phenomenon of uneven mixing will be doubled, leading to a large number of unqualified products and huge losses. Summary of the Invention

[0003] The purpose of the present invention is to provide a production process of compound food additives, which performs secondary directional processing on the raw materials initially mixed and processed according to the detection data, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A production process of compound food additives includes a terminal control system and a production module integrated with multi-level induction monitoring of processing raw materials. The production module includes a machine body, a processing chamber is arranged in the machine body, a sensor module for detecting the characteristics of the raw materials during processing is arranged in the processing chamber, a processing module for adjusting the processing position area according to the detected characteristic data is arranged between the top of the machine body and the processing chamber. The sensor module detects the characteristics of the raw materials in different vertical and horizontal directions, and at the same time sends the detection data to the terminal control system. The terminal control system analyzes the processing degree of different regions of the raw materials through the characteristic data in the vertical and horizontal directions, and at the same time locates according to the characteristic data in the vertical and horizontal directions, and adjusts the processing module to perform centralized processing on the area with the lowest processing degree.

[0005] Preferably, the processing module includes a central disk and a main ring body. A number of arc-shaped connecting rods are fixedly installed between the inner side wall of the main ring body and the inner ring of the central disk. A sliding ring is slidably connected to each arc-shaped connecting rod. An extension column is fixedly provided at the top end of each sliding ring. The lower end face of the central disk is fixedly connected to a key shaft. The bottom end of the key shaft is spline-connected to a sleeve. The bottom end of the sleeve is fixedly connected to a fixed end head. An elastic mixing member is fixedly connected between the bottom end of the fixed end head and the bottom end of each sliding ring. The elastic mixing member spirally surrounds the sleeve. A longitudinal adjustment assembly for the up-and-down contraction adjustment of the elastic mixing member and the heat dissipation of the processed raw material is provided at the bottom end of the fixed end head. A transverse adjustment assembly is provided on the upper end face of the main ring body. The transverse adjustment assembly drives the sliding ring to slide along the arc-shaped connecting rod for adjustment.

[0006] Preferably, the longitudinal adjustment assembly includes a bottom platform part and a telescopic airbag member. The bottom platform part is rotatably installed at the bottom of the processing cavity. An inner concave cavity is provided in the bottom platform part. The telescopic airbag member is installed in the inner concave cavity. The upper end face of the telescopic airbag member is fixedly connected to the bottom end face of the fixed end head. A number of air outlet blocks are equidistantly distributed and installed on the upper end face of the telescopic airbag member. Each air outlet block is in communication with the air outlet end in the telescopic airbag member. The air outlet blocks surround the outer end face of the fixed end head. The air inlet end at the bottom of the telescopic airbag member is communicated with a trachea. The trachea is communicated with an external air source. By controlling the amount of gas introduced into the telescopic airbag member, the rising distance of the fixed end head is controlled to achieve the longitudinal adjustment of the elastic mixing member. At the same time, when resetting, the gas is released to dissipate the heat of the processed raw material. When the elastic mixing member is longitudinally contracted and adjusted, the pitch of the elastic mixing member can be shortened, and thus the density of the elastic mixing member is greater, and the incomplete processing area can be further deeply processed twice.

[0007] Preferably, the transverse adjustment assembly includes an adjustment disk two fixedly installed on the upper end face of the main ring body. A number of chute two corresponding to the position and quantity of the arc-shaped connecting rods are distributed in the adjustment disk two. Each extension column slidably passes through the corresponding chute two. The upper end face of the adjustment disk two is rotatably connected to an adjustment disk one. A number of chute one corresponding to the chute two are equidistantly distributed in the adjustment disk one. Each extension column penetrates into the chute one. Driving the adjustment disk one to rotate drives the extension column to move along the chute two towards the center direction for horizontal adjustment of the elastic mixing member, so that the elastic mixing member can reciprocally contract and expand in the horizontal direction, and the raw material can be fully and efficiently mixed and processed.

[0008] Preferably, the sensor module includes an inclined mounting table, a detection mounting rod, and sensors. The detection mounting rod is fixedly mounted on the central disk, the inclined mounting table is fixedly mounted on the side wall of the processing cavity, the sensors are distributively mounted on the detection mounting rod and the inclined end surface of the inclined mounting table. The sensors on the detection mounting rod and the sensors on the inclined mounting table are located on the same horizontal plane in the horizontal position. The characteristic data detected by the sensors is transmitted to the terminal control system, and the terminal control system adjusts the intake air volume in the telescopic airbag member and the rotation angle of the second adjusting disk according to the data.

[0009] Preferably, a top cover is fixedly mounted on the upper end surface of the machine body. An extension portion is provided at the bottom edge of the main ring body. An inner ring groove is provided at the position of the extension portion on the inner end surface of the top cover. The extension portion is slidably connected in the inner ring groove. A connection cover is provided on the extension portion. A connection portion is fixedly provided at the bottom of the connection cover, and a fixed connection is made between the connection portion and the upper end surface of the extension portion.

[0010] Preferably, a connection column is fixedly mounted on the upper end surface of the second adjusting disk, and a mounting cylinder is fixedly mounted on the upper end surface of the first adjusting disk. The mounting cylinder is hollow inside and penetrates the lower end surface of the first adjusting disk. The connection column is rotatably connected in the inner space of the mounting cylinder. A second servo motor is fixedly mounted on the lower end surface of the connection cover, and the output end of the second servo motor is fixedly connected to the upper end surface of the mounting cylinder.

[0011] Preferably, a control adjustment method for the processing module to perform centralized processing on the area with the lowest processing degree specifically includes the following steps: S1: After the preliminary processing is completed, the sensors on the inclined mounting table and the detection mounting rod respectively perform characteristic detection on the raw material, and upload the detected characteristic data to the terminal control system; S2: The terminal control system projects the characteristic data detected by each sensor onto a two-dimensional coordinate system according to the position in the processing cavity. Among them, the sensors located on the detection mounting rod are set from bottom to top as: {A1(0, y1), A2(0, y2), A3(0, y3), A4(0, y4)……, An(0, yn)}, and the sensors located on the inclined mounting table are set from bottom to top as: {B1(x1, y1), B2(x2, y2), B3(x3, y3), B4(x4, y4)……, Bn(xn, yn)}, and each point carries corresponding characteristic data; S3: Analyze the characteristic data of each point. If the characteristic data in more than half of the points deviates from the set standard range, re-perform the preliminary processing. If the characteristic data in more than half of the points is within the set standard range, then enter S4; S4: Extract the point M with the largest deviation of characteristic data from the set standard range, and the adjacent point N in the horizontal direction. Compare and analyze the characteristic data of the two points adjacent to M in the vertical direction, select the point C with the largest difference in characteristic data from point M, and at the same time extract the point D adjacent to point C in the horizontal direction; S5: Analyze the characteristic data among the four extracted points M, N, C, and D, analyze the area with the lowest processing degree, and perform directional secondary processing on the area with the lowest processing degree: S6: Loop the above steps until the characteristic data of each point is within the set standard range.

[0012] Preferably, the analysis of the characteristic data between the extracted points in step S5 specifically includes the following methods: If the characteristic data of three or more points including M deviate from the set standard range among the four points, the raw material area of the vertical distance between M and N is determined as the area with the lowest processing degree. At this time, the terminal control system controls the air intake volume in the telescopic airbag component to move the fixed end to the vertical distance position closest to the bottom of the processing cavity among the four points; If the characteristic data of M and N both deviate from the set standard range, and the characteristic data of C and D do not deviate from the set standard range, then calculate the vertical distance △y between C and N, the difference value K between the characteristic data of C and D closest to the standard range and the characteristic data of M and N most deviated from the standard range, and the difference value Q between the characteristic data of the standard range and the characteristic data of M and N most deviated from the standard range. Then the offset distance Y = (△y * Q) / K; If M is above C, the terminal control system controls the air intake volume in the telescopic airbag component to move the fixed end above C, with a vertical distance of Y from C; If M is below C, the terminal control system controls the air intake volume in the telescopic airbag component to move the fixed end below M, with a vertical distance of Y from M; If only the characteristic data of M deviates from the set standard range, first, according to the above steps, the terminal control system controls the air intake volume in the telescopic airbag component to move the fixed end to the corresponding position, and then controls the second servo motor to drive the first regulating disc to make the slip ring slide along the arc-shaped connecting rod towards the center area, so that the elastic mixing component moves to the center position in the horizontal direction between M and N.

[0013] Preferably, during the preliminary processing, the terminal control system controls the second servo motor to drive the first regulating disc to rotate uniformly in a reciprocating manner, and controls the elastic mixing component to uniformly reciprocate and contract and expand from the outside to the inside during the preliminary processing to achieve comprehensive processing of the raw materials.

[0014] In summary, the beneficial effects of the present invention are: In the mixing and processing process of the present invention, first, the raw materials are preliminarily mixed and processed. After a period of time, the sensor is activated to detect the particle size distribution data and humidity of the raw materials after preliminary mixing and processing at different points. At the same time, according to the particle size distribution data, a processing degree of the preliminary processing is judged. If there are uneven areas in the raw materials after preliminary mixing and processing, then according to the detected data, the area with the lowest processing degree is planned, and at the same time, the processing module is controlled to adjust the processing position area to perform directional secondary deep processing on the uneven areas that appear in the preliminary processing process, ensuring the uniformity of raw material mixing in all directions. It can also reduce the density difference between particles, avoid layering phenomena caused by vibration or gravity during transportation or storage, and maintain the long-term stability of the compound food additive.

[0023] The following combinationFigures 1-9 A detailed description of the present invention is given. For the convenience of description, the following directions are defined as follows: The up-down, left-right, front-back directions mentioned below are the same as the up-down, left-right, front-back directions of the Figure 3 viewing direction, Figure 3 which is the front view of the device of the present invention, Figure 3 and the directions shown are the same as the up-down, left-right, front-back directions of the front view direction of the device of the present invention.

[0024] Please refer to Figures 1-9 , an embodiment provided by the present invention: A production process of a compound food additive, preparing a compound leavening agent, which is an additive commonly used in food processing, mainly used in baking products to help the dough or batter expand, increase the volume and softness of the product. The proportion of its product formula is:

[0025] The first step: Raw material pretreatment All raw materials need to pass through an 80-mesh sieve to remove lumps and impurities.

[0026] The acidic salts (sodium acid pyrophosphate, glucono-δ-lactone, potassium bitartrate) and the basic salt (sodium bicarbonate) are stored separately to avoid moisture absorption and pre-reaction.

[0027] Precautions: The moisture content of the raw materials needs to be <0.5% (detection standard). If the humidity exceeds the standard, it needs to be dried first (vacuum drying at 60°C for 2 hours).

[0028] The humidity of the screening environment is controlled below 40% to prevent moisture absorption and caking.

[0029] The second step: Mixing and processing procedure Key steps in the preparation process, including a production module and a terminal control system. The production module includes a body 10, in which a processing chamber is provided. In the processing chamber, a sensor module for detecting the characteristics of the raw materials during processing is provided. Here, the detection of the characteristics of the raw materials includes the humidity and the particle size distribution degree during the raw material processing. The particle size distribution data is the main data, and the humidity data is the auxiliary data to ensure the mixing uniformity of the acidic salt and the alkaline salt, thereby ensuring the chemical activity and the use effect of the leavening agent. The humidity and the particle size distribution degree are used as the raw material characteristic data of the raw materials. In the processing chamber, a processing module is installed. The processing module can be adjusted according to whether the humidity and the particle size distribution degree detected by the sensor module are within the set standard range, so as to adjust the processing position area to perform directional secondary processing on the uneven areas that appear during the preliminary processing. The sensor module detects the characteristics of the raw materials in different vertical and horizontal directions, and at the same time sends the detection data to the terminal control system. The terminal control system analyzes the processing degree of different areas of the raw materials through the characteristic data in the vertical and horizontal directions, and at the same time locates according to the characteristic data in the vertical and horizontal directions, and adjusts the processing module to perform centralized processing on the area with the lowest processing degree, so as to ensure that the humidity and the particle size distribution degree of the raw materials during the mixing process are maintained within the set standard range at each position, and ensure the chemical activity and the use effect of the leavening agent. It is worth mentioning that in this embodiment, the processing module includes a central disk 27 and a main ring body 26. A plurality of arc-shaped connecting rods 28 are fixedly installed between the inner side wall of the main ring body 26 and the inner ring of the central disk 27. According to the inner diameter of the main ring body 26, six are selected here. Each of the arc-shaped connecting rods 28 is slidably connected with a sliding ring 34. The top of each sliding ring 34 is fixedly provided with an extension column 35. The lower end surface of the central disk 27 is fixedly connected with a key shaft 30. The bottom end of the key shaft 30 is spline-connected with a sleeve 31. The bottom end of the sleeve 31 is fixedly connected with a fixed end 33. An elastic mixing member 29 is fixedly connected between the fixed end 33 and the bottom end of each sliding ring 34. The elastic mixing member 29 spirally surrounds the sleeve 31. The spirally surrounding elastic mixing member 29 is used to fully mix and process the raw materials in the processing chamber. A longitudinal adjustment component for the up and down contraction adjustment of the elastic mixing member 29 and the heat dissipation of the processed raw materials is provided at the bottom end of the fixed end 33. A transverse adjustment component is provided on the upper end surface of the main ring body 26. The transverse adjustment component drives the sliding ring 34 to slide along the arc-shaped connecting rod 28 for adjustment; A top cover 14 is fixedly installed on the upper end face of the body 10. An extension part is provided at the bottom edge of the main ring body 26. An inner ring groove is provided at the position of the extension part on the inner end face of the top cover 14. The extension part is slidably connected in the inner ring groove. A connecting cover 17 is provided on the extension part. A connecting part 18 is fixedly provided at the bottom of the connecting cover 17. The connecting part 18 is fixedly connected to the upper end face of the extension part. A servo motor 15 is installed on the upper end face of the top cover 14. The output end of the servo motor 15 passes through the top cover 14 and is fixedly connected to the connecting cover 17; When preliminary processing is carried out, the servo motor 15 starts to drive the connecting cover 17 to rotate, thereby driving the entire main ring body 26 to rotate, so that the elastic mixing part 29 fully mixes and processes the raw materials in the processing cavity.

[0030] It is also worth mentioning that, in this embodiment, the longitudinal adjustment assembly includes a bottom table part 36 and a telescopic airbag part 37. The bottom table part 36 is rotatably installed at the bottom of the processing cavity. An inner concave cavity is provided in the bottom table part 36. The telescopic airbag part 37 is installed in the inner concave cavity. The upper end face of the telescopic airbag part 37 is fixedly connected to the bottom end face of the fixed end 33. A plurality of air outlet blocks 38 are equidistantly distributed and installed on the upper end face of the telescopic airbag part 37. Each air outlet block 38 is in communication with the air outlet end in the telescopic airbag part 37. The air outlet blocks 38 surround the outer end face of the fixed end 33. The air inlet end at the bottom of the telescopic airbag part 37 is communicated with a trachea 11, and a one-way valve is provided at the communication position. The trachea 11 is communicated with an external air source, and nitrogen is selected here; When it is necessary to adjust the upward movement of the fixed end 33, the terminal control system controls nitrogen to enter the telescopic airbag member 37, and uses the control amount to control the extension distance of the telescopic airbag member 37, so as to realize the control of the rising distance of the fixed end 33, so that the elastic mixing member 29 contracts longitudinally, the pitch of the elastic mixing member 29 becomes shorter, making the elastic mixing member 29 denser and the mixing of raw materials more delicate and sufficient. After the fixed end 33 rises, the raw materials at the bottom part cannot form mixing and stirring, and thus cannot dissipate heat. As time goes by, the temperature of the raw materials at the bottom part will gradually increase, which will have a certain impact on the raw materials. At this time, after the longitudinal adjustment and secondary directional processing, the nitrogen in the telescopic airbag member 37 is controlled to be discharged for contraction and reset. When the nitrogen is discharged, the fixed end 33 continuously descends, and the discharged nitrogen overflows into the raw materials at the bottom part through the air outlet block 38. The discharged nitrogen is filled into the raw materials at the bottom part to take away the heat contained in the raw materials at the bottom part, realizing the heat discharge of the processed raw materials, and further ensuring the quality of the processed raw materials. Since the elastic mixing member 29 at the top continuously mixes and stirs the raw materials, it will continuously dissipate heat from the raw materials, avoiding heat accumulation.

[0031] It should be noted that in this embodiment, the horizontal adjustment assembly includes an adjustment disk two 23 fixedly installed on the upper end surface of the main ring body 26. The adjustment disk two 23 is provided with sliding grooves two 24 corresponding to the positions and quantities of the arc-shaped connecting rods 28. Each extension column 35 slides through the corresponding sliding groove two 24 respectively. The upper end surface of the adjustment disk two 23 is rotatably connected with an adjustment disk one 21. The adjustment disk one 21 is equidistantly provided with sliding grooves one 22 corresponding to the sliding grooves two 24. Each extension column 35 respectively penetrates into the sliding groove one 22. Driving the adjustment disk one 21 to rotate drives the extension column 35 to move along the sliding groove two 24 towards the center direction to horizontally adjust the elastic mixing member 29. The upper end surface of the adjustment disk two 23 is fixedly installed with a connecting column 25. The upper end surface of the adjustment disk one 21 is fixedly installed with an installation cylinder 20. The installation cylinder 20 is hollow inside and penetrates the lower end surface of the adjustment disk one 21. The connecting column 25 is rotatably connected in the internal space of the installation cylinder 20. The lower end surface of the connecting cover 17 is fixedly installed with a servo motor two 19. The output end of the servo motor two 19 is fixedly connected with the upper end surface of the installation cylinder 20; The terminal control system is used to control the drive of the second servo motor 19, so as to control the rotation angle and rotation speed of the first adjustment disk 21, and then use the rotation of the first adjustment disk 21 to drive the sliding of the extension column 35, so that the slip ring 34 slides along the arc-shaped connecting rod 28, and the elastic mixing member 29 is adjusted to contract from the outside to the inside, adjusting the lateral distance of the elastic mixing member 29. Cooperating with the longitudinal adjustment assembly, the elastic mixing member 29 can perform directional secondary processing on the raw materials with low processing degree in the processing cavity.

[0032] In addition, in one embodiment, the sensor module includes an inclined mounting table 16, a detection mounting rod 32 and a sensor 40. The sensor 40 can be an NIR sensor for detecting the humidity and particle size distribution degree of the raw materials. The detection mounting rod 32 is fixedly installed on the central disk 27, close to the key shaft 30. The inclined mounting table 16 is fixedly installed on the side wall of the processing cavity. The sensors 40 are distributed and installed on the detection mounting rod 32 and the inclined end surface of the inclined mounting table 16. The sensor 40 at the bottom end of the inclined mounting table 16 is close to the fixed end 33. The sensors 40 on the detection mounting rod 32 and the sensors 40 on the inclined mounting table 16 are located on the same horizontal plane in the horizontal position. The sensors 40 on the detection mounting rod 32 are used to detect the raw material characteristic data at different depth positions in the processing cavity, while the sensors 40 on the inclined mounting table 16 are used to detect the raw material characteristic data at different horizontal positions in the processing cavity. At the same time, a comparison is made with the sensors 40 on the detection mounting rod 32 at the depth position. If the raw material characteristic data detected by the sensors 40 on the detection mounting rod 32 are all within the set standard range, while the data detected by the sensors 40 on the inclined mounting table 16 are different, it can be judged that the raw materials in the horizontal transverse direction are unevenly mixed and processed. If the detection data of the sensors 40 on the inclined mounting table 16 and the detection mounting rod 32 at the same horizontal position are all within the set standard range, but are indeed not within the standard range in the longitudinal direction, it can be judged that the raw materials are unevenly mixed and processed in the longitudinal depth.

[0033] The characteristic data detected by the sensor 40 are transmitted to the terminal control system, and the terminal control system adjusts the air intake volume in the telescopic airbag member 37 and the rotation angle of the second adjustment disk 23 according to the data, and controls the elastic mixing member 29 to contract to the position area with the lowest processing degree for secondary mixing and processing.

[0034] When specifically mixing and processing the raw materials, first mix the acidic salt and starch, and finally add sodium bicarbonate. Gradually add the raw materials into the processing cavity through the feeding hopper 13. First, use the terminal control system to control the start of the first servo motor 15 for preliminary processing, drive the main ring body 26 to rotate, so that the elastic mixing part 29 rotates to mix and process the raw materials. During the preliminary processing, the terminal control system controls the second servo motor 19 to drive the first adjusting disk 21 to rotate at a constant speed in a reciprocating manner, and controls the elastic mixing part 29 to uniformly and reciprocally contract and expand from the outside to the inside during the preliminary processing, so as to achieve comprehensive processing of the raw materials; After the preliminary processing is completed, the inclined surface mounting table 16 and the sensor 40 on the detection mounting rod 32 respectively perform characteristic detections on the humidity and particle size distribution degree of the raw materials, and upload the detected characteristic data to the terminal control system; The terminal control system projects the characteristic data detected by each sensor 40 onto a two-dimensional coordinate system according to its position in the processing cavity. Among them, the sensors 40 on the detection mounting rod 32 are arranged from bottom to top as: {A1(0, y1), A2(0, y2), A3(0, y3), A4(0, y4)}, and the sensors 40 on the inclined surface mounting table 16 are arranged from bottom to top as: {B1(x1, y1), B2(x2, y2), B3(x3, y3), B4(x4, y4)}, and each point position carries corresponding characteristic data; Analyze the characteristic data of each point position. If the characteristic data in more than half of the point positions deviates from the set standard range, re-perform the preliminary processing until the characteristic data in more than half of the point positions is within the set standard range; for example, set a standard range of characteristic data, the humidity is (37%±2%)RH, and the average particle size of the particle size distribution is (80±5)μm.

[0035] When the characteristic data in more than half of the point positions is within the set standard range, extract the point position M with the largest deviation of the characteristic data from the set standard range, and the adjacent point position N in the horizontal direction. Compare and analyze the characteristic data of the two point positions adjacent to M in the vertical direction, select the point position C with the largest difference in characteristic data from the point position M, and at the same time extract the point position D adjacent to the point position C in the horizontal direction; Reference Figure 9 For example, the positions of the four point positions are: M(x3, y3), N(0, y3), C(x2, y2), D(0, y2); Analyze the characteristic data among the four extracted point positions M, N, C, and D, mainly based on the particle size distribution data and supplemented by the humidity data, analyze the area with the lowest processing degree, and perform directional secondary processing on the area with the lowest processing degree; If the characteristic data of four points deviate from the set standard range at three or more points including M, the raw material area of the layer of the longitudinal distance between M and N is recognized as the area with the lowest processing degree. At this time, the terminal control system controls the air intake volume in the telescopic airbag part 37 to move the fixed end 33 to the longitudinal distance position closest to the bottom of the processing cavity among the four points; For example: M(x3, y3), with an average particle size of 67μm and a humidity of 35%RH; N(0, y3), with an average particle size of 70μm and a humidity of 37%RH; C(x2, y2), with an average particle size of 69μm and a humidity of 35%RH; D(0, y2), with an average particle size of 80μm and a humidity of 37%RH; Only point D is within the set standard range. In the entire processing cavity, the raw materials of the layer from point D to point N are all areas with the lowest processing degree. Therefore, this part needs to be re-mixed and processed. At this time, the terminal control system controls the air intake volume in the telescopic airbag part 37 to move the fixed end 33 to the position of point D, and makes the elastic mixing part 29 shrink a part, shortening the pitch to re-mix and process the raw materials above point D. If the characteristic data of M and N both deviate from the set standard range, and C and D do not deviate from the set standard range. For example: M(x3, y3), with an average particle size of 67μm and a humidity of 35%RH; N(0, y3), with an average particle size of 70μm and a humidity of 37%RH; C(x2, y2), with an average particle size of 83μm and a humidity of 35%RH; D(0, y2), with an average particle size of 78μm and a humidity of 37%RH; Then there is an uneven mixing phenomenon in the plane layer of M and N. At this time, calculate the longitudinal distance △y = |y3 - y2| between C and N. The characteristic data of C and D closest to the standard range is 78μm, and the characteristic data of M and N most deviated from the standard range is 67μm. At this time, the difference value K between the two is 11μm. The difference value Q between the characteristic data of the standard range and the characteristic data of M and N most deviated from the standard range is 13μm. Then the offset distance Y = (△y * Q) / K = (|y3 - y2| * 13) / 11 If M is above C, the terminal control system controls the air intake volume in the telescopic airbag part 37 to move the fixed end 33 above C, with a longitudinal distance of Y from C, and re-mixes and processes the upper part of the raw materials. If M is below C, the terminal control system controls the air intake in the telescopic airbag member 37 so that the fixed end 33 moves below M, with a longitudinal distance of Y from M. If only the characteristic data of M deviates from the set standard range, for example: M(x3, y3), with an average particle size of 67 μm and a humidity of 35%RH; N(0, y3), with an average particle size of 80 μm and a humidity of 37%RH; C(x2, y2), with an average particle size of 83 μm and a humidity of 35%RH; D(0, y2), with an average particle size of 78 μm and a humidity of 37%RH; Then, first, according to the above steps, the terminal control system controls the air intake in the telescopic airbag member 37 so that the fixed end 33 moves to a position Y distance above C, first determines the longitudinal orientation, and then controls the second servo motor 19 to drive the first adjustment disk 21, so that the slip ring 34 slides along the arc-shaped connecting rod 28 towards the center area, moves the elastic mixing member 29 to the center position in the transverse direction of M and N, adjusts the transverse orientation, and aligns the tangent point of the elastic mixing member 29 on the MN transverse line with the center position of the MN transverse line. At this time, control the elastic mixing member 29 to rotate to perform secondary mixing processing on the raw materials. During the mixing process, also control the elastic mixing member 29 to reciprocate and contract uniformly between the point M and the center point of the MN transverse line, and perform secondary processing on the raw materials in the interval between the center point of the MN horizontal line and the point M, the point C, and the point on the CD horizontal line extended from the center point of the MN horizontal line. Refer to Figure 9 .

[0036] Finally, loop the above steps until the characteristic data of each point is within the set standard range, ensuring the uniformity of the raw material mixing, comprehensively controlling the functionality, safety, and stability of the compound leavening agent. Once the mixing is uneven, it will cause the reaction rate of the leavening agent to be unstable, affecting the volume and texture of the final product. During the mixing process, first, perform preliminary mixing processing on the raw materials. After a period of time, start the sensor 40 to detect the particle size distribution data and humidity of the raw materials after preliminary mixing processing at different points. At the same time, judge the processing degree of the preliminary processing according to the particle size distribution data. If there are uneven areas in the raw materials after preliminary mixing processing, plan the area with the lowest processing degree according to the detected data, and at the same time control the processing module to adjust the processing position area to perform directional secondary deep processing on the uneven areas that appear during the preliminary processing, which can also reduce the density difference between particles and avoid stratification caused by vibration or gravity during transportation or storage, maintaining the long-term stability of the leavening agent.

[0037] Ensure the uniformity of raw material mixing to avoid the following problems caused by partial excess or deficiency: 1. Unstable expansion effect: Excessive local acidic or alkaline components may cause early or delayed reactions, resulting in uneven expansion of food (such as excessive expansion in some areas and collapse in other areas).

[0038] 2. Residual odor or bitterness: Unreacted alkaline components (such as sodium bicarbonate) will leave a bad taste.

[0039] Controlling the humidity during the mixing process can effectively ensure 1. Prevent caking and moisture absorption failure Hygroscopic ingredients in leavening agents (such as certain acid salts or starch) are sensitive to humidity: Too high humidity: It is easy to cause the particles to absorb moisture and agglomerate, destroy the uniformity of mixing, and even trigger premature chemical reactions (such as sodium bicarbonate and acidic salts releasing CO2 prematurely in a humid environment).

[0040] Humidity that is too low: may increase dust generation, affecting mixing process safety (such as dust explosion risk) and worker health.

[0041] 2. Control reaction rate Humidity directly affects the activation time of the leavening agent: During the baking or cooking process of food, moisture is the key factor that triggers the reaction of the leavening agent. If the humidity inside the leavening agent is uneven, it may lead to inconsistent CO2 release rate and affect the texture of the food (such as uneven hole size inside the cake).

[0042] 3. Extend shelf life Controlling humidity can prevent the performance of the leavening agent from deteriorating due to moisture absorption or water loss during storage: Moisture absorption may trigger a slow reaction between ingredients, reducing the leavening effect; Excessive drying may render certain functional additives (such as emulsifiers) ineffective.

[0043] The synergistic effect of mixing uniformity and humidity 1. Humidity assisted mixing Appropriate humidity (such as 40%~60% RH) can reduce electrostatic adsorption of particles, promote fluidity, and indirectly improve mixing uniformity. However, excessive moisture should be avoided to prevent agglomeration.

[0044] 2. Uniform humidity distribution A well-mixed leavening agent ensures that moisture is evenly distributed among the particles, avoiding agglomeration or reaction failure caused by humidity differences in local areas.

[0045] After the overall mixing of the raw materials is completed, enter the third step: sieving and homogenizing The mixed materials are passed through a 100-mesh vibrating screen of the machine body to remove the soft lumps formed during the mixing process.

[0046] Precautions: The screen mesh needs to be regularly checked for damage to prevent metal debris from mixing in.

[0047] The materials after screening need to be immediately transferred to a closed container to reduce the exposure time.

[0048] Step 4: Drying treatment Parameters: Temperature: 50 - 55 °C (to avoid the decomposition of sodium bicarbonate, the critical temperature is 60 °C).

[0049] Time: 30 - 40 minutes (fluidized bed drying).

[0050] The final moisture content ≤ 1.0% (detected by a rapid moisture meter).

[0051] Precautions: After drying, it needs to be cooled to room temperature (below 25 °C) before packaging to prevent moisture absorption due to temperature difference.

[0052] Step 5: Sub-packaging and packaging Equipment: Automatic quantitative packaging machine (nitrogen replacement filling).

[0053] Requirements: Packaging material: Aluminum foil composite film (moisture permeability < 0.5 g / m²·24h).

[0054] Sealing strength > 50 N / 15mm (heat seal test).

[0055] Precautions: The purity of the nitrogen filled ≥ 99.9%, and the residual oxygen content < 1%.

[0056] 200 g of samples are retained for each batch and stored for 6 months after the expiration date of the shelf life.

[0057] As described above, it is only the specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any changes or substitutions that can be thought of without creative work should be covered within the protection scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
