Description

Technical Field

[0001] The invention relates to the technical field of bread production equipment, in particular to prebiotic compounding equipment for steamed cakes. Background Art

[0002] The main ingredients of prebiotic steamed cake are flour, yeast, eggs, oil, sugar and an appropriate amount of salt. On this basis, prebiotic powder is mixed in. The low sweetness of prebiotic powder, the improvement of intestinal environment, the lowering of blood sugar and other physiological effects make the prebiotic steamed cake not only satisfy the taste, but also bring many health benefits to consumers. Prebiotic steamed cake can effectively promote the growth of beneficial bacteria in the intestines, improve the intestinal microecological environment, and thus improve the body's ability to absorb nutrients. In addition, the dietary fiber rich in the cake helps to enhance satiety, reduce overeating, and reduce the burden on the stomach after eating steamed cake. Its low sugar and low fat characteristics help reduce the risk of obesity and prevent chronic diseases such as diabetes, which meets the needs of modern healthy diet.

[0003] However, the amount of prebiotics mixed in and the type of prebiotics have become important factors affecting the quality of steamed cakes. The amount of prebiotic powder added is added in percentage to the weight of flour added, and is mixed with multiple prebiotics. In the prior art, after weighing the flour mass, the theoretical amount of prebiotics added is obtained manually or by using a calculator, and then weighed manually. This process is not only time-consuming and labor-intensive, but also prone to errors due to human factors, and has a low degree of automation. In the actual production process, the actual amount of flour may change due to various reasons, and the method of manual calculation and then weighing cannot make timely corrections to the amount of prebiotics added according to the actual amount of flour, resulting in low accuracy of the amount of prebiotics added. The inaccurate amount of prebiotics added will directly affect the taste, nutritional value and health benefits of the steamed cake, causing fluctuations in the production quality of prebiotic steamed cakes.

[0040] Embodiment 1: A preparation process of a prebiotic steamed cake, comprising the prebiotic steamed cake in Embodiment 1, comprising the following steps:

[0041] S1. Raw material preparation: weigh the raw materials according to weight fraction and place them separately;

[0042] S2. Beating the egg liquid: Beat the egg liquid weighed in S1 for a beating time of T1;

[0043] S3. Fat whipping: whip the fermented cream weighed in S1 for a whipping time of T2

[0044] S4. Adding prebiotics: The prebiotics weighed in S1 and the whipped cream fermented cream in S3 are added to the whipped egg liquid in S2 and stirred evenly to obtain a composite slurry, and the stirring time is T3;

[0045] S5. Making cake batter: uniformly stirring the composite slurry in S4 and the remaining raw materials in S1 to obtain a cake batter;

[0046] S6. Pre-fermentation of cake batter: The dough in S5 is placed in an environment with a temperature of 5 to 6°C and a relative humidity of 58 to 62% and fermented for 16 hours;

[0047] S7. Cake batter injection molding: The cake batter in S6 is injected into the mold plate, and then placed in a tunnel-type bread fermentation chamber for fermentation, controlling the temperature at 38 to 40°C and the relative humidity at 75 to 80%, and fermenting for 135 to 145 minutes;

[0048] S8. Steaming cake batter: Put the cake batter in S7 into a steaming device, control the heating temperature to 100-110° C., steam time T4=10-14 minutes, perform steam heating, and demould after cooling to form a steamed cake.

[0049] Among them, the raw material preparation in S1 adopts the following formula by weight fraction, 69-70 parts of flour, 11.4 parts of white sugar, 6.9-7 parts of prebiotics, 6.5-6.9 parts of egg liquid, 6.1-6.3 parts of milk fat fermented cream, 2.4-2.5 parts of milk powder, 1.35-1.37 parts of yeast, 1.3 parts of trehalose, 0.11-0.13 parts of salt, and 11.5-12 parts of drinking water. The actual amount of the prebiotics added is 1% of the actual amount of the flour added, and the prebiotics are added at a ratio of 1% of the amount of flour added, that is, 1g of prebiotics is added for every 100g of flour added. Since oligosaccharide prebiotics can affect the rheological properties and processing properties of the dough, and have physiological effects such as low sweetness, improving the intestinal environment, and lowering blood sugar, by adding prebiotics, the edible health of the steamed cake is improved, and the steaming quality of the cake is improved.

[0050] Among them, prebiotics are added to S4 using the following weight fraction formula: 10% xylooligosaccharide, 20% cyclodextrin, 30% fructo-oligosaccharide and 40% galacto-oligosaccharide, and are added after compounding.

[0051] Example 2: Figure 1-10 As shown, a prebiotic compounding device for steamed cakes is used for preparing the prebiotic steamed cakes in Example 1, comprising a weighing mechanism 1, a arranging mechanism 2, a stirring mechanism 3, a stirring barrel 4, a machine base 5, and a control module. The stirring barrel 4 is located on one side of the machine base 5. The arranging mechanism 2 and the weighing mechanism 1 are both assembled with the machine base 5, and the arranging mechanism 2 is located above the stirring barrel 4. The control module is electrically connected to the weighing mechanism 1, the arranging mechanism 2, and the stirring mechanism 3 respectively. The weighing mechanism 1 comprises a first weight sensor and a containing box 102. The machine base 5 is provided with a detection cavity 501, and the detection cavity 501 is located below the arranging mechanism 2. The containing box 102 is used to contain flour and is placed in the detection chamber 501. The first weight sensor is installed in the detection chamber 501 to measure the weight m0 of the flour and input the weight m0 into the control module. The control module calculates f(m0)=A according to m0, and instructs the arranging mechanism 2 to discharge the prebiotics of A weight into the mixing barrel 4. The stirring mechanism 3 is used to stir the prebiotics in the mixing barrel 4 under the instruction of the control module. The arranging mechanism 2 is provided with N groups for respectively discharging N kinds of prebiotics. The N groups of arranging mechanisms 2 are electrically connected to the control module. The weights of the prebiotics discharged by the N groups of arranging mechanisms 2 are a1~a N ; Where f(m0) = e × m0, e is a pre-entered fixed value, 0.5% ≤ e ≤ 1.5%; Where A = a1 + ... + aN , a1=b1%×A、…、a N =b N %×A, b1%~b N % is the fixed value of the prebiotic weight percentage input in advance, b1%+…+b N %=100%.

[0052] By providing a control module, after the actual weight of the flour is weighed by the weighing mechanism, the weight of the prebiotics to be added is calculated, and the prebiotics are transported to the mixing barrel 4 for mixing through the discharging mechanism, thereby improving the degree of automation of prebiotic compounding and the precision and controllability of the amount of prebiotics added, thereby ensuring the quality of the prebiotic cake. Of course, the first weight sensor needs to be reset to zero before detection, that is, when the containing box 102 is not filled with flour, its weight is detected by the first weight sensor and then reset to zero.

[0053] Among them, the stirring mechanism 3 includes a stirring motor 301, a stirring blade 302, a cutting blade 303, and a stirring roller 304. The stirring blade 302 and the cutting blade 303 are connected to the stirring roller 304 and are alternately arranged along the axis of the stirring roller 304. The stirring blade 302 is provided with multiple groups for stirring the prebiotic powder in the stirring barrel 4. The cutting blade 303 is provided with multiple groups for crushing the prebiotic powder in the stirring barrel 4. The stirring roller 304 is rotatably assembled with the stirring barrel 4. The stirring motor 301 is assembled above the stirring barrel 4 and is used to rotate the stirring roller 304. The control module is electrically connected to the stirring motor 301 and is used to input rotation and stop instructions of the stirring motor 301. A discharge pipe 401 is connected to the bottom of the stirring barrel 4 for discharging prebiotics, and the discharge pipe 401 is connected to a valve 402.

[0054] Among them, the stirring blade 302 is arranged in an arc shape, and there are two groups of stirring blades 302. The stirring blade 302 located at the top is provided with two arc parts, and the two arc parts are symmetrically arranged up and down. The stirring blade 302 located at the bottom is provided with an arc part with an arc mouth facing upward, and the arc part is adapted to the inner wall of the stirring barrel 4. The cutting blade 303 is provided with a contraction part, and the contraction part is gradually contracted from the cutting blade 303 close to the axis of the stirring roller 304 to both ends, thereby improving the compounding and stirring quality of the prebiotic powder. Of course, four groups of stirring blades 302 are arranged in the same radial direction, and the stirring blades 302 are arranged at equal angles along the axis of the stirring roller 304. Four groups of cutting blades 303 are arranged in the same radial direction, and the cutting blades 303 are arranged at equal angles along the axis of the stirring roller 304, so that the prebiotic powder can flow from the gaps between the stirring blades 302 and the gaps between the cutting blades 303 and the cutting blades 303, and thus be discharged from the discharge pipe 401 of the stirring barrel 4.

[0055] In terms of the specific connection structure of the control template controlling the fixed row mechanism 2 to discharge prebiotics, the fixed row mechanism 2 includes a support seat 201, a discharge barrel 202, a fixed row member 203, a lead screw 204, a slider 205, and a fixed row motor 206. A discharge chamber 2021 is provided on the side wall of the discharge barrel 202. The fixed row member 203 is adapted to the inner wall of the discharge chamber 2021 and is used to push out the prebiotics in the discharge chamber 2021. The lead screw 204 is rotatably assembled with the support seat 201. The slider 205 is threadedly connected to the lead screw 204 and moves along the axis of the lead screw 204. The fixed end of the fixed row motor 206 is assembled on the support seat 201 and its rotating end is axially connected to the lead screw 204. The side of the fixed row member 203 close to the slider 205 is connected to the slider 205 through a connecting rod. The fixed row motor 206 is used to rotate an angle θ under the command of the control module.

[0056] Among them, the fixed displacement motor 206 is a servo motor, which can accurately control the rotation angle and speed. The support seat 201 is provided with a limiter for limiting the slider 205. There are two groups of limiters and they are respectively located on both sides of the slider 205, which are used to limit the movement of the slider 205 along the axis of the screw 204.

[0057] The control module is pre-input with the cross-sectional area S of the discharge chamber 2021, the pitch P of the lead screw 204, and the material density ρ of the prebiotics. The control module calculates the rotation angle θ of the fixed row motor 206 according to the weight A = (A×360°) / (S×P×ρ), and instructs the fixed row mechanism 2 to discharge the prebiotics of weight A into the mixing barrel 4; wherein the control module is pre-input with the material densities ρ1~ρ N , the rotation angle θ1 of the first group of the arranging mechanism 2 corresponding to the first prebiotic is = (a1×360°) / (S×P×ρ1), the rotation angle θ1 of the first group of the arranging mechanism 2 corresponding to the Nth prebiotic is N =(a N ×360°) / (S×P×ρ N ), according to weight = volume × density, volume = cross-sectional area × height, by controlling the rotation angle of the fixed row motor 206, the slider 205 moves on the lead screw 204, and the moving distance is the height of the above-mentioned calculated volume, so that the added amount of prebiotics is converted into the rotation angle of the fixed row motor 206, which is convenient for controlling the added amount of prebiotics through the control module, and improving the controllability of the added amount of prebiotics. Of course, in order to improve the addition accuracy, the smaller the pitch P of the lead screw 204, the smaller the controllable minimum unit, and the higher the accuracy. The lead screw 204 pitch P used in this embodiment is 1 mm.

[0058] In order to facilitate the replenishment of the prebiotics in the discharge barrel 202, the cross-section of the discharge chamber 2021 is set in a trapezoidal shape, and the length of the upper bottom is smaller than the length of the lower bottom. The top wall of the discharge barrel 202 is provided with a feeding port connected to the discharge chamber 2021, and the feeding port is extended along the moving direction of the fixed row member 203. When the slider 205 moves to the end of the lead screw 204 close to the fixed row motor 206, the side wall of the fixed row member 203 is flush with the side wall of the feeding port. If the prebiotic powder is added into the discharge chamber 2021 from the feeding port, until the prebiotic powder completely fills the entire discharge chamber 2021, the control module controls the fixed row member 203 to push the fixed row member 203 to reduce the pressure. The weight of the prebiotic powder discharged may be less than the actual weight, thereby improving the accuracy. The discharge chamber 2021 is arranged in a trapezoidal shape, so that when the prebiotic powder is added, it is accumulated in the discharge chamber 2021 into a shape that matches the inner wall of the discharge chamber 2021, thereby improving the filling degree of the inner wall of the discharge chamber 2021 by the prebiotic powder. Of course, the trapezoidal shape of the inner wall of the discharge chamber 2021 can be obtained through multiple tests to obtain the most suitable shape for the addition of prebiotic powder, or the prebiotic powder enters the discharge chamber 2021 through the feeding port, and the operator uses a flattening tool to scrape the prebiotics in the discharge chamber 2021 flat to reduce the error.

[0059] In order to facilitate the addition of prebiotics through the feeding port, the arranging mechanism 2 also includes a blocking piece 211, a blocking cylinder 212, and a feed barrel 213 arranged in an inverted trapezoid and used to hold prebiotic powder. The feed barrel 213 is assembled above the discharge barrel 202, and an opening is arranged at the upward end of the feed barrel 213, and the downward end of the feed barrel 213 is connected to the feeding port. A sliding hole is arranged at the end of the feed barrel 213 close to the arranging motor 206, and the blocking piece 211 is slidably assembled with the sliding hole and is used to open and close the feeding port. The bottom wall of the blocking piece 211 is flush with the inner top wall of the discharge chamber 2021, the blocking cylinder 212 is connected to the support seat 201 and is used to push the blocking piece 211 to move back and forth, and the control module is electrically connected to the blocking cylinder 212 to control the blocking cylinder 212 to push the blocking piece 211 to move back and forth, and the arranging member 203 moves to the prebiotics in the discharge chamber 2021 When the powder is pushed out for discharge, the blocking piece 211 is in a state of closing the feeding port, that is, at this time, the discharge barrel 202 is not connected to the feed barrel 213. When the fixed row member 203 moves to the end of the screw 204, the prebiotic powder in the discharge barrel 202 is completely emptied. At this time, it is necessary to add prebiotic powder to the discharge chamber 2021. The operator operates, and the control module controls the blocking cylinder 212 to control the blocking piece 211 to contract, so that the discharge barrel 202 is connected to the feed barrel 213. The prebiotic powder in the feed barrel 213 fills the entire discharge chamber 2021 under the action of its own weight. At this time, the operator operates, and the control module controls the blocking cylinder 212 to control the blocking piece 211 to extend, so that the discharge barrel 202 is not connected to the feed barrel 213. At the same time, the blocking piece 211 has a certain leveling effect on the prebiotic powder in the discharge chamber 2021 during the movement.

[0060] After the fixed arrangement member 203 pushes the prebiotic powder in the discharge barrel 202 to move a preset distance, the discharge of the prebiotic powder is completed. In order to prevent the prebiotic powder in the discharge chamber 2021 from being abnormally discharged from the opening of the discharge barrel 202, the present embodiment further includes a sealing mechanism 7 for opening and closing the opening of the discharge chamber 2021. The sealing mechanism 7 includes a sealing plate 701 and a sealing cylinder 702. The sealing plate 701 moves up and down along the opening of the discharge chamber 2021 and is used to open and close the discharge chamber 2021. The sealing cylinder 702 is located below the discharge barrel 202 and is used to push the sealing plate 701 to move up and down. The control module is electrically connected to the sealing motor and is used to output the push rod extension and retraction instructions of the push cylinder. The fixed end of the sealing cylinder 702 is connected to the support seat 201, and the pushing end of the sealing cylinder 702 is connected to the bottom wall of the sealing plate 701. When the control module wants to control the feeding piece to move forward, it first controls the sealing cylinder 702 to move down and open the sealing plate 701, so as to facilitate the discharge of the prebiotic powder in the discharge chamber 2021. When the control module controls the fixed discharge mechanism 2 to complete the discharge of the prebiotic powder in the discharge chamber 2021, the control module controls the sealing cylinder 702 to move up and close the sealing plate 701.

[0061] In order to improve the sealing performance of the sealing plate 701 to the opening of the discharge chamber 2021, the sealing plate 701 is arranged in a square shape, and a convex edge strip 7011 is arranged on the side of the sealing plate 701 facing the discharge chamber 2021. The edge strip 7011 is arranged in a U shape. When the push rod of the sealing cylinder 702 is in an extended state, the bottom wall of the edge strip 7011 abuts against the bottom wall of the discharge cylinder 202. When the sealing cylinder 702 pushes the sealing plate 701 to move, the two side walls of the edge sealing strip 7011 slide along the two side walls of the discharge barrel 202, which limits the sliding of the sealing plate 701. The bottom wall of the edge sealing strip 701 abuts against the bottom wall of the discharge barrel 202, reducing the risk of prebiotic powder overflowing from the gap between the discharge chamber 2021 and the sealing plate 701, and improving the airtightness of the sealing plate 701 to the opening of the discharge chamber 2021.

[0062] In order to improve the accuracy of the amount of prebiotic powder added, the present embodiment further includes a detection mechanism 8 for weighing the prebiotic powder discharged by the arranging mechanism 2. The detection mechanism 8 is assembled on the support seat 201. The detection mechanism 8 includes a hopper 801, a second weight sensor, and a buzzer. The buzzer is electrically connected to the control module. The second weight sensor is electrically connected to the control module and is used to detect the weight D of the prebiotics in the hopper 801. The control module calculates the motor rotation angle compensation coefficient ε of the lead screw 204 according to (AD) / A, and issues the following command:

[0063] When 10%≤(AD) / A<0, the control module instructs the control to adjust the rotation angle of the lead screw 204 motor of the next arrangement mechanism 2 to θ-ε;

[0064] When 0<(AD) / A≤10%, the control module instructs the control to adjust the rotation angle of the lead screw 204 motor of the next arrangement mechanism 2 to θ+ε;

[0065] When 10%<(AD) / A, the control module instructs the sealing cylinder 702 to shrink, driving the sealing plate 701 to move downward, and the control module instructs the rotation angle of the lead screw 204 motor of the arranging mechanism 2 to be adjusted to θ+θ0, and the control module instructs the rotation angle of the lead screw 204 motor of the arranging mechanism 2 to be adjusted to θ+ε next time;

[0066] When (AD) / A<10%, the control module instructs the buzzer to operate and sound an alarm;

[0067] Wherein, ε=[(AD)×360°] / (S×P×ρ).

[0068] By setting the rotation angle compensation coefficient ε, the discharge of the fixed discharge mechanism 2 is fed back to improve the discharge accuracy of the prebiotic powder and reduce the error. Of course, the weight signal detected by the second weight sensor is the weight of the prebiotic, that is, when the hopper 801 is not filled with prebiotic powder, the second weight sensor is reset to zero.

[0069] The detection mechanism 8 is provided with N groups relative to the arrangement mechanism 2, and the weights detected by the N groups of second weight sensors are d1 to d2. N The control module is pre-input with N different prebiotic material densities ρ1~ρ N The rotation angle compensation coefficient ε1 of the first group of arrangement motor 206 of the first prebiotic group is [(a1-d1)×360°] / (S×P×ρ), and the rotation angle compensation coefficient εN of the Nth group of arrangement motor 206 of the Nth prebiotic group is [(a1-d1)×360°] / (S×P×ρ). N -d N )×360°] / (S×P×ρ).

[0070] In order to facilitate the delivery of the prebiotic powder in the discharge barrel 202 to the hopper 801, and the delivery of the prebiotic powder in the hopper 801 to the mixing barrel 4, the sealing mechanism 7 also includes an inclined plate 703. The sealing mechanism 7 is provided with an inclined plate 703 connected to the top wall of the sealing plate 701 and located on the side away from the sealing strip. The inclined plate 703 is inclined from top to bottom, and the angle between the inclined plate 703 and the sealing plate 701 is 45° to 60°. When the sealing plate 701 moves downward and opens, the inclined plate 703 is connected to the bottom wall of the discharge chamber 2021 and the hopper 801. The stirring tank is provided with a feed port 404, the detection mechanism 8 also includes a rotating motor 804, the hopper 801 is rotatably assembled with the support seat 201, the rotating motor 804 is assembled on the support seat 201, and is used to rotate the hopper 801 to pour the prebiotic powder into the feed port 404, the feed port 404 is connected to the feed manifold 4031, and the feed manifold 4031 is provided with N groups of manifolds, and the openings of the manifolds correspond to the N groups of detection mechanisms 8 respectively, which are used to collect the prebiotic powders of the N groups of detection mechanisms 8 and then enter the stirring barrel 4 through the feed port 404.

[0071] In order to reduce the amount of prebiotic powder remaining on the inclined plate 703 and scattering under the up and down movement of the sealing cylinder 702, thereby increasing the cleaning workload of the compounding equipment and reducing the waste of prebiotic powder, the inclined plate 703 is provided with a baffle portion and a rotating shaft 7032. The baffle portion 7031 is rotatably assembled with one end of the inclined plate 703 close to the hopper 801. The rotating shaft 7032 is penetrated through the middle of the baffle portion and is used to rotatably assemble the baffle portion 7031 and the inclined plate 703. The rotating shaft 7032 forms the fulcrum of the baffle portion, and the baffle portion is exposed on the top surface of the inclined plate 703. The hopper 801 is provided with a push block 8011, which is located below the inclined plate 703 and on one side of the rotating shaft 7032. When the sealing plate 701 moves downward to open, the push block 8011 abuts against one side of the baffle portion. The top surface of the baffle portion is flush with the top surface of the inclined plate 703, so that the prebiotic powder is smoothly transported from the discharge chamber 2021 to the hopper 801. When the control module issues an instruction to control the sealing cylinder 702 to move upward, the inclined plate 703 moves away from the hopper 801, so that the baffle portion 7031 is separated from the push block 8011. When there is no external force, the baffle portion 7031 is exposed on the top surface of the inclined plate 703, thereby blocking the prebiotic powder remaining on the inclined plate 703 to prevent it from being scattered due to force during the movement of the sealing cylinder 702. When the baffle portion 7031 is exposed on the top surface of the inclined plate 703 without the action of external force, it can be achieved by controlling the gravity difference on both sides of the fulcrum. This is a conventional method and will not be described in detail.

[0072] In order to realize the normal rotation of the barrier part 7031, an activity space 7033 for the barrier part 7031 to rotate needs to be opened on the inclined plate 703. The opening of the activity space 7033 will cause the prebiotic powder to slide from the inclined plate 703 into the activity space 7033, which will cause blockage. In order to solve the above technical problems, the barrier part 7031 is arranged in an L shape, and the sealing mechanism 7 also includes a spacer 704 and a spring 7041. The spacer 704 is provided with two groups, and is respectively located on the left and right sides of the barrier part 7031. Two groups of corresponding spacers 704 are provided, one end of the spring 7041 is connected to one end of the spacer 704, and the other end of the spring 7041 is connected to the side wall of the activity space 7033, and the other end of the spacer 704 is abutted against the barrier part 7031. The first spacer 704 is located on the left side of the barrier part 7031, and the second spacer 704 is located on the right side of the barrier part 7031. When the barrier part 7031 is When there is no external force, when the barrier part is exposed on the top surface of the inclined plate 703, the spring 7041 of the first barrier 704 is in a reset state. Of course, at this time, the spring 7041 still has enough elastic force to make the first barrier 704 abut against the side wall of the barrier part 7031, and the spring 7041 of the second barrier is in a compressed state. When the push block 8011 lifts the barrier part 7031, the spring 7041 of the first barrier 704 is in a compressed state, and the spring 7041 of the second barrier is in a reset state. Similarly, at this time, the spring 7041 still has enough elastic force to make the second barrier 704 abut against the side wall of the barrier part 7031, so that when the barrier part rotates, the prebiotic powder will not fall into the activity space 7033. It is worth mentioning that, in the absence of external force, the barrier part 7031 can offset the elastic force of the spring 7041 of the second barrier 704, so that the barrier part is exposed on the top surface of the inclined plate 703.

[0073] Among them, there are 4 kinds of prebiotics, namely N=4, namely 10% of the weight of the fabric xylooligosaccharide a1, the corresponding density is ρ1, 20% of the weight of the fabric cyclodextrin a2, the corresponding density is ρ2, 30% of the weight of the fabric oligofructose a3, the corresponding density is ρ3, 40% of the weight of the fabric galacto-oligosaccharide a4, the corresponding density is ρ4, the pitch P of the 4 groups of lead screws 204 are all 1mm, and the cross-sectional area of ​​the 4 groups of discharge cavities 2021 are all S.

[0074] During use, in step 1, the operator inputs the addition ratio b1-b4 of the prebiotics, the density of the prebiotics, the pitch of the lead screw 204, and the cross-sectional area of ​​the discharge chamber 2021 into the control module in advance. Of course, the preset can also be completed in advance before the equipment leaves the factory; step 2, add the prebiotics into the corresponding feed barrel 213, and add them in sequence according to the prebiotic density preset in the control module. Of course, the equipment can be marked to avoid wrong addition; step 3, the operator operates the control module so that the blocking cylinder 212 pushes the blocking sheet 211 away, so that the prebiotics in the discharge barrel 202 can flow smoothly into the discharge barrel 202. At this time, the sealing cylinder 702 is in an extended state, and the sealing plate 701 makes the discharge barrel 202 in a closed state. Of course, the operator can use a compacting tool to flatten the prebiotic powder, but it will not compress the prebiotic powder into blocks to avoid block-shaped discharge. To cause a greater error, the operator operates the control module to close the blocking piece 211, separate the feed barrel 213 from the discharge barrel 202, and continue to add prebiotic powder to the discharge barrel 202, thereby reducing the frequency of adding prebiotic powder during normal operation of the equipment; Step 4, the flour is placed in the container 102 and transported to the detection chamber 501 for weight detection. At this time, the control module performs calculations and controls the fixed discharge mechanism 2 to discharge a fixed amount of prebiotic powder into the mixing barrel 4. The four prebiotics are added according to a preset ratio and enter the mixing barrel 4 through the feed manifold 4031; Step 5, the control module controls the stirring motor 301 to rotate, thereby stirring and compounding the prebiotics in the mixing barrel 4. After the stirring is completed according to the preset stirring time, the control module controls the stirring motor 301 to stop, and the operator opens the valve 402 of the discharge pipe 401 to discharge the compounded prebiotic powder.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
