[0002] Noodles are the main food raw material in the world today. my country has a long history of noodle-making, with a wide variety of styles. Dough mixing is a key link in the processing of noodle products, and the taste of noodles is directly related to dough mixing. Dough mixing refers to the process of evenly mixing wheat flour and water under appropriate intensity stirring to form dough, which is a key process in noodle production. Factors affecting the dough mixing effect include the amount of water added, dough mixing time, stirring speed, blade shape, etc. How to mix flour and liquid, balance the relationship between dough mixing time, stirring speed and temperature rise, simulate artificial dough mixing methods, and form the best gluten network structure are difficult problems that the industry needs to solve.

[0003] In the industrial production of noodles, the types of dough mixers mainly include vertical, horizontal, high-speed continuous and vacuum dough mixers. Horizontal dough mixers are the most commonly used dough mixers in the production of dried noodles, including single-axis and double-axis types.

[0007] Preferably, the left spiral stirring shaft and the right spiral stirring shaft are arranged in reverse symmetry with the dough kneading axis as the center, and the vertical distance between each point on the left spiral stirring shaft and the right spiral stirring shaft and the dough kneading axis is consistent.

[0008] Further preferably, the left spiral stirring shaft and the right spiral stirring shaft are respectively connected to the dough kneading main shaft through the two radial connecting arms.

[0009] Preferably, the left spiral stirring shaft and the right spiral stirring shaft are spiral structures centered on the dough kneading axis, and the rotation angle between the two is 90°.

[0010] Preferably, the kneading balls penetrate the left spiral stirring shaft and the right spiral stirring shaft, and the diameter and spacing of the kneading balls are equal.

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

[0023] C. The control device in the present invention controls the rotation direction, rotation speed and kneading time of the kneading spindle by frequency conversion regulation, and controls the kneading process in stages according to the properties of the dough, and executes four kneading modes in sequence, including fast mixing of flour, medium-speed three-dimensional kneading, and slow flexible dough beating process (control of forward and reverse rotation), so as to better blend flour and water, promote the formation of the gluten network structure inside the dough, and meet the requirements of imitating artificial high water addition kneading.

[0024] D. The present application installs a left spiral stirring shaft and a right spiral stirring shaft on the dough mixing shaft in an anti-symmetrical manner, so that the dough mixing shaft is subjected to more uniform force when rotating in the dough mixing pot; a plurality of kneading balls evenly distributed on the left and right spiral stirring shafts realize kneading of local points of the dough during the process of pushing the dough through spiral extrusion, so that the dough moves from the two ends of the dough mixing shaft to the middle and from the middle to the two ends, simulating the process of human hand kicking the dough, and the fusion of water and flour allows the internal tendon structure of the dough to be quickly formed. Combined with the set dough mixing mode running time, it can be used for the processing of different special noodle products. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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-added kneading dough mixer, comprising a frame 1 and a dough mixing pot body 2, a dough mixing motor 6 and a control device 7 arranged on the frame 1. The dough mixing pot body 2 is provided with an openable and closable pot cover assembly 3, the control device is electrically connected to the dough mixing motor 6, and a dough mixing main shaft 5 arranged along its axial direction is provided inside the dough mixing pot body 2. The dough mixing main shaft 5 is connected to a transmission main shaft 8 located on the outside of the dough mixing pot body 2. Here, the dough mixing main shaft 5 can form an integral structure with the transmission main shaft 8 and be connected to the frame 1. The transmission main shaft 8 is driven and connected to the dough mixing motor 6. Of course, the dough mixing motor 6 is preferably a variable frequency motor, which can adjust the rotation speed of the dough mixing main shaft. At the same time, 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, and 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 the left spiral stirring shaft 9 and the right spiral stirring shaft 10 are installed on both sides of the transmission main shaft 8 through a radial connecting arm 20 fixed on the transmission main shaft 8, and a plurality of kneading balls 30 are respectively provided on the left spiral stirring shaft 9 and the right spiral stirring shaft 10. Figure 3 As shown, the left spiral stirring shaft 9 and the right spiral stirring shaft 10 are respectively connected to the dough kneading main shaft 5 through 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 kneading main shaft 5, and the rotation angle between the two is 90°.

[0037] The left spiral stirring shaft 9 and the right spiral stirring shaft 10 are arranged in reverse symmetry with the dough main axis 5 as the center, so that the dough main axis 5 is subjected to more uniform rotation force, and each point on the left spiral stirring shaft 9 and the right spiral stirring shaft 10 is at the same vertical distance from the dough main axis 5. Each kneading ball 30 is connected in series to the left and right spiral stirring shafts, and the diameter and spacing of each kneading ball 30 are equal, that is, the distance between each kneading ball and the dough main axis is consistent. The distance between two adjacent kneading balls 30 is 50-200mm, and the ratio of the diameter of the kneading ball to the diameter of the left and right spiral stirring shafts is 5-10.

[0038] The pot cover assembly 3 preferably adopts pneumatic adjustment, including a pot cover 31, a powder supply port 32 arranged on the pot cover 31, a water supply pipe 33, a pressure relief port 34 and a rotating mechanism 35. The rotating mechanism 35 is connected to the pot cover 31 and the dough mixing pot body 2. The pot cover 31 will rotate a certain angle under the action of the rotating mechanism 35, so that the pot cover 31 is fully opened. When the rotating mechanism 35 is controlled to rotate in the opposite direction, the pot cover 31 will seal the upper opening of the dough mixing pot body 2. Of course, the powder supply port 32 can be connected to a metering powder supply device (not shown in the figure) to inject a certain amount of flour into the dough mixing pot body 2. The water supply pipe 33 can also be connected to a water supply device (not shown in the figure) to inject a certain amount of water into the dough mixing pot body 2. The addition ratio and amount of flour and water are controlled by the control device 7. The pressure relief port 34 on the dough mixing pot body 2 is used to discharge the gas in the dough mixing pot body 2.

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

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

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

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

[0043] The specific dough kneading process is as follows: the automatic metering powder supply device and water supply device are equipped, the corresponding speed and time in each dough kneading mode are set on the operation screen, the pot cover 31 is closed under the action of the flip motor 4, the flour and water enter the dough kneading pot body 2 through the powder supply port 32 and the water supply pipe 33 on the upper part of the pot cover assembly 3 according to the proportion requirements, the internal air is discharged to the outside of the dough kneading pot body 2 through the pressure relief port 34, the dough kneading spindle 5 stirs and mixes the flour and water under the action of the dough kneading motor 6, and then goes through the steps of rapid powder mixing (after powder supply, water supply + water powder mixing), medium speed three-dimensional kneading (promoting starch hydrolysis to form gluten), slow flexible dough treading (enhancing gluten network) and forward and reverse rotation, so as to form a dough with uniform texture. After the dough kneading is completed, the flip motor 4 is controlled to operate, so that the dough kneading pot body 2 is flipped 180 degrees, the outlet of the dough kneading pot body 2 faces downward, and the dough is taken out under the reverse rotation of the dough kneading spindle 5.

[0044] Specific parameters can be set on the operation screen of the control device 7, for example:

[0045] The dough kneading capacity is 200kg / time (flour dosage), the amount of water added is 48%, the amount of salt added is 1.5%, the moisture content of the dough is 41%, the dough kneading cycle is 20 minutes (including 2 minutes for dough in and out), and the temperature rise of the dough kneading is ≤5℃.

[0046] (1) Fast 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) Flexible kicking mode: forward rotation, speed 10-15 rpm, time 3 minutes;

[0049] Reverse, speed 10-15rpm, time 3 minutes.

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

[0051] The control device 7 in the present invention controls the rotation direction, rotation speed and kneading time of the kneading main shaft 5 by frequency conversion regulation, and controls the kneading process in stages according to the properties of the dough, and executes four kneading modes in sequence, including fast mixing of flour, medium-speed three-dimensional kneading, and slow flexible dough kicking process (control of forward and reverse rotation). While the dough rotates in a spiral, part of the dough rolls from the left and right ends to the middle, accompanied by bionic actions such as kneading, pinching, and kicking, presenting a multi-dimensional three-dimensional motion state, so that the flour and water are better integrated, and the formation of the gluten network structure inside the dough is promoted, meeting the requirements of imitating artificial high water addition kneading. The amount of water added to the flour can reach 46%-52%, so that the moisture content of the dough reaches 40.3%-42.6%.

[0052] Anything not described in the present invention is applicable to the prior art.

[0053] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
