Description

Technical Field

[0001] This invention belongs to the field of food processing technology and equipment, and more specifically, relates to a high-water-addition kneading and mixing machine for the kneading technology stage of processing flour products (noodles, steamed buns, dumplings, etc.). Background Technology

[0002] Noodles are a major food ingredient in the world today, and my country has a long history of noodle-based foods, with a wide variety and diverse styles. Kneading is a crucial step in noodle processing, directly affecting the taste of the noodles. Kneading refers to the process of uniformly mixing wheat flour and water under appropriate stirring intensity to form a dough; it is a key step in noodle production. Factors affecting kneading include the amount of water added, kneading time, stirring speed, and blade shape. How to achieve optimal flour-water mixing, balance the relationship between kneading time, stirring speed, and temperature rise, simulate manual kneading, and form the best gluten network structure is a challenge that the industry needs to solve.

[0003] In the industrial production of noodles, dough mixing equipment mainly comes in various forms, including vertical, horizontal, high-speed continuous, and vacuum dough mixers. Horizontal dough mixers are the most widely used type in dried noodle production, and include single-shaft and double-shaft models. Based on the combination of mixing speeds, dough mixers can be further divided into constant-speed and variable-speed types. Currently, dough mixers used for noodle processing generally add less than 36% water, while traditional handmade hollow noodles typically add more than 50% water. Developing high-water-addition dough mixers that can improve noodle quality is a current industry need. Summary of the Invention

[0004] To address the shortcomings of traditional noodle-making machines, such as insufficient water addition, poor flour-water integration, and inability to effectively promote the formation of the gluten network within the dough, this invention provides a high-water-addition kneading machine that meets the requirements of mimicking manual high-water kneading, thereby improving noodle quality.

[0005] The technical solution adopted is as follows:

[0006] A high-water-injection kneading and mixing machine includes a frame, a kneading pot body, a kneading motor, and a control device mounted on the frame. The kneading pot body is equipped with an openable and closable lid assembly. The control device is electrically connected to the kneading motor. A kneading spindle is provided in the kneading pot body along its axial direction. The kneading spindle is connected to a transmission spindle located on the outside of the kneading pot body. The transmission spindle is driven by the kneading motor. The kneading spindle is also equipped with a left-hand spiral stirring shaft and a right-hand spiral stirring shaft. The left-hand spiral stirring shaft and the right-hand spiral stirring shaft are arranged front and rear along the axial direction of the kneading spindle. The left-hand spiral stirring shaft and the right-hand spiral stirring shaft are mounted on both sides of the transmission spindle via radial connecting arms fixed on the transmission spindle. Each of the left-hand spiral stirring shaft and the right-hand spiral stirring shaft is equipped with a plurality of kneading balls.

[0007] Preferably, the left and right spiral stirring shafts are arranged symmetrically in opposite directions with the dough kneading main shaft as the center, and the vertical distance between each point on the left and right spiral stirring shafts and the dough kneading main shaft is consistent.

[0008] More preferably, the left helical stirring shaft and the right helical stirring shaft are respectively connected to the dough mixing spindle via two radial connecting arms.

[0009] Preferably, the left and right spiral stirring shafts are spiral structures centered on the dough mixing spindle, and their rotation angle is 90°.

[0010] Preferably, the kneading balls pass through the left and right helical stirring shafts, and the diameter and spacing of each kneading ball are equal.

[0011] The diameter ratio between the kneading ball and the left and right spiral stirring shafts is 5-10; the distance between two adjacent kneading balls is 50-200mm.

[0012] Furthermore, the frame is also equipped with a flipping motor connected to the dough mixing pot, and the control device is electrically connected to the flipping motor to control the flipping angle of the dough mixing pot from 0° to 180°.

[0013] Furthermore, the lid of the pot lid assembly is provided with a powder supply port, a water supply pipe and a pressure relief port that are connected to the dough mixing pot body. The powder supply port and the water supply pipe are respectively connected to a metering powder supply device and a water supply device for injecting flour and water into the dough mixing pot body. The pressure relief port is used to release the gas in the dough mixing pot body.

[0014] Preferably, the control device controls the speed, direction, and running time of the dough mixing motor to sequentially execute four dough mixing modes on the dough mixing pot: rapid powder mixing mode, three-dimensional kneading mode, gentle dough-kneading mode, and dough-extrusion mode.

[0015] Preferably, the rapid powder mixing mode is: forward rotation, speed 20-30 rpm, time 2-4 min;

[0016] The three-dimensional kneading mode: forward rotation, speed 15-20 rpm, time 8-10 min;

[0017] The flexible treading mode: forward rotation, speed 10-15 rpm, time 2-4 min;

[0018] Reverse the direction, speed 10-15 rpm, time 2-4 minutes;

[0019] The dough output mode: control the lid of the pot lid assembly to open, control the flipping motor to flip, so that the outlet of the dough mixing pot faces downward.

[0020] The technical solution of the present invention has the following advantages:

[0021] A. The high-water-addition kneading and mixing machine provided by this invention adopts a unique structural form that combines the left and right spiral stirring shafts with kneading balls with the main kneading shaft. While the dough rotates spirally in the kneading pot, some dough flakes are rolled from both ends to the middle under the action of the left and right spiral stirring shafts. When the direction is reversed, the dough rolls from the middle to both ends. The kneading balls on the left and right spiral stirring shafts squeeze and knead the local dough, making the dough present a multi-dimensional three-dimensional motion state, simulating the biomimetic actions of kneading, pinching, and kicking of manual dough kneading, thereby improving the quality of the dough.

[0022] B. This invention uses a control device to automatically control the powder supply, water supply, lid opening and closing, pot rotation, and dough mixing parameters, achieving automated dough mixing and scooping, thus changing the current situation where dough mixing relies on manual intervention. Because the entire dough mixing process takes place in a relatively enclosed environment within the mixing pot, the influence of the external environment on the dough mixing process is avoided, ensuring hygiene and safety during processing.

[0023] C. The control device in this invention controls the rotation direction, rotation speed and kneading time of the kneading spindle by frequency conversion regulation. It controls the kneading process in stages according to the characteristics of the dough, and executes four kneading modes in sequence, including fast mixing, medium-speed three-dimensional kneading and slow soft kneading process (controlling forward and reverse rotation), so that the flour and water can be better integrated, promote the formation of the gluten network structure inside the dough, and meet the requirements of imitating artificial high-water kneading.

[0024] D. This application installs a left-hand spiral mixing shaft and a right-hand spiral mixing shaft on the dough mixing main shaft in an anti-symmetrical manner, so that the dough mixing main shaft is subjected to more uniform force when rotating in the dough mixing pot; several kneading balls evenly distributed on the left and right spiral mixing shafts achieve local kneading of the dough through spiral extrusion and pushing of the dough, so that the dough exhibits a process that imitates the process of human hand kneading dough as it moves from both ends of the dough mixing main shaft to the middle and from the middle to both ends. The fusion between water and flour allows the internal gluten structure of the dough to form quickly. Combined with the set dough mixing mode running time, it can be used for processing different special-purpose dough products. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1 and Figure 2As shown, the present invention provides a high-water-injection kneading and mixing machine, including a frame 1 and a kneading pot 2, a kneading motor 6, and a control device 7 mounted on the frame 1. The kneading pot 2 is provided with an openable and closable lid assembly 3. The control device is electrically connected to the kneading motor 6. Inside the kneading pot 2, there is a kneading spindle 5 arranged along its axial direction. The kneading spindle 5 is connected to a transmission spindle 8 located on the outside of the kneading pot 2. Here, the kneading spindle 5 and the transmission spindle 8 can form an integral structure and be connected to the frame 1. The transmission spindle 8 and the kneading motor 6 form a drive connection. Of course, the kneading motor 6 is preferably a variable frequency motor, which can adjust the speed of the kneading spindle. Meanwhile, the present invention also provides a left spiral stirring shaft 9 and a right spiral stirring shaft 10 on the dough mixing main shaft 5. The left spiral stirring shaft 9 and the right spiral stirring shaft 10 are arranged front and back along the axial direction of the dough mixing main shaft 5, and are mounted on both sides of the transmission main shaft 8 via radial connecting arms 20 fixed on the transmission main shaft 8. The left spiral stirring shaft 9 and the right spiral stirring shaft 10 are each provided with a plurality of kneading balls 30. For example... Figure 3 As shown, the left spiral stirring shaft 9 and the right spiral stirring shaft 10 are connected to the dough mixing main shaft 5 via two radial connecting arms 20. The left spiral stirring shaft 9 and the right spiral stirring shaft 10 are spiral structures centered on the dough mixing main shaft 5, and their rotation angle is 90°.

[0037] The left and right spiral mixing shafts 9 and 10 are arranged symmetrically in opposite directions around the main mixing shaft 5, ensuring more even force distribution during rotation. Furthermore, the perpendicular distance between each point on the left and right spiral mixing shafts 9 and 10 and the main mixing shaft 5 remains consistent. Kneading balls 30 are connected in series on the left and right spiral mixing shafts, with equal diameters and spacing, ensuring a consistent distance between each kneading ball and the main mixing shaft. The distance between adjacent kneading balls 30 is 50-200mm, and the ratio of the kneading ball diameter to the diameter of the left and right spiral mixing shafts is 5-10.

[0038] The pot lid assembly 3 preferably employs pneumatic adjustment, including a pot lid 31, a powder inlet 32, a water supply pipe 33, a pressure relief port 34, and a rotating mechanism 35. The rotating mechanism 35 is connected to the pot lid 31 and the kneading pot body 2. Under the action of the rotating mechanism 35, the pot lid 31 will rotate at a certain angle, making the pot lid 31 fully open. When the rotating mechanism 35 is controlled to rotate in the opposite direction, the pot lid 31 will seal the upper opening of the kneading pot body 2. Of course, the powder inlet 32 ​​can be connected to a metering powder supply device (not shown in the figure) for injecting a certain amount of flour into the kneading pot body 2, and the water supply pipe 33 can also be connected to a water supply device (not shown in the figure) for injecting a certain amount of water into the kneading pot body 2. The ratio and amount of flour and water added are controlled by the control device 7. The pressure relief port 34 on the kneading pot body 2 is used to release the gas in the kneading pot body 2.

[0039] According to production needs, the present invention controls the ratio of flour to water. Before the dough is kneaded, the pot lid 31 is closed by the rotating mechanism 35 to supply flour, water and mix flour and water. The air inside the kneading pot 2 is discharged to the outside of the kneading pot 2 through the pressure relief port 34. After the dough is kneaded, the pot lid 31 is opened by the rotating mechanism 35 to take out the dough and complete the entire kneading process.

[0040] In addition, the present invention mounts the dough mixing pot 2 on the frame 1, and the frame 1 is also provided with a flipping motor 4 connected to the dough mixing pot 2. The control device 7 is electrically connected to the flipping motor 4 and is used to control the flipping angle of the dough mixing pot 2 to be 0° to 180°.

[0041] The dough kneading spindle 5 in this invention can be frequency-controlled and set to rotate forward and reverse according to different dough kneading modes under the action of the dough kneading motor 6.

[0042] The control device 7 is installed on the frame 1 and can set parameters and monitor the process of the entire dough mixer. The rotation direction of the dough mixing spindle 5 can be set to forward or reverse. The control is divided into manual mode and fully automatic mode, and the dough mixing cycle is about 20 minutes.

[0043] The specific dough kneading process is as follows: An automatic flour and water metering device is used. The speed and time for each kneading mode are set on the control panel. The lid 31 closes under the action of the flipping motor 4. Flour and water enter the kneading pot 2 according to the required proportions through the flour inlet 32 ​​and water pipe 33 on the upper part of the lid assembly 3, respectively. Internal air is discharged to the outside of the kneading pot 2 through the pressure relief port 34. The kneading spindle 5, under the action of the kneading motor 6, mixes the flour and water, sequentially going through rapid flour mixing (water supply + flour mixing after flour supply), medium-speed three-dimensional kneading (promoting starch hydrolysis to form gluten), slow-speed gentle kneading (strengthening the gluten network), and forward and reverse rotation, forming a uniform dough. After kneading, the flipping motor 4 is controlled to rotate the kneading pot 2 180°, with the outlet of the kneading pot 2 facing downwards. The dough is then removed under the reverse rotation of the kneading spindle 5.

[0044] Specific parameters can be set on the operation screen of control device 7, as shown in the following example:

[0045] The dough kneading capacity is 200kg / batch (flour usage), with 48% water and 1.5% salt added. The dough moisture content is 41%, the kneading cycle is 20 minutes (including 2 minutes for entering and exiting the dough), and the kneading temperature rise is ≤5℃.

[0046] (1) Quick mixing mode: forward rotation, speed 20-30 rpm, time 3 minutes.

[0047] (2) Three-dimensional kneading mode: forward rotation, speed 15-20 rpm, time 9 minutes.

[0048] (3) Soft treading mode: forward rotation, speed 10-15 rpm, time 3 minutes;

[0049] Reverse the direction, turn the speed to 10-15 rpm, and wait for 3 minutes.

[0050] Of course, the speed, direction, and running time can be adjusted according to the requirements of the dough products being made, which will not be elaborated here.

[0051] The control device 7 in this invention controls the rotation direction, speed, and kneading time of the kneading spindle 5 by frequency conversion regulation. It controls the kneading process in stages according to the dough properties, and executes four kneading modes in sequence, including fast mixing, medium-speed three-dimensional kneading, and slow-speed gentle kneading (controlling forward and reverse rotation). While the dough is rotating in a spiral, some dough flakes roll from the left and right ends to the middle, accompanied by biomimetic movements such as kneading, pinching, and kneading, presenting a multi-dimensional three-dimensional motion state. This allows the flour and water to blend better, promotes the formation of the gluten network structure inside the dough, and meets the requirements of artificial high-water kneading. The water content in the flour can reach 46%-52%, so that the dough moisture content reaches 40.3%-42.6%.

[0052] Any aspects not covered in this invention are applicable to existing technologies.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
