Description

Technical Field

[0001] The invention relates to the technical field of mixing or kneading machines for making dough, and in particular to a digital dough mixer and a working method thereof. Background Art

[0002] The main function of a dough mixer is to mix flour and water evenly. A dough mixer generally consists of a bowl, a mixing blade, a transmission device, an electrical box, a machine base, etc. The mixing blade is driven by the transmission device to rotate in the bowl. At the same time, the mixing blade rotates at a constant speed driven by the transmission device. The flour in the bowl is constantly pushed, pulled, kneaded, and pressed, fully stirred, and mixed quickly, so that the dry flour is evenly hydrated, the gluten is expanded, and it becomes a dough with a certain elasticity, stretchability, and uniform flow. The quality of the dough will affect the quality of the food made from the dough. The quality of the dough is usually judged by the gluten expansion state of the dough.

[0003] In the process of kneading dough, the existing dough mixer requires the operator to constantly observe the gluten expansion of the dough. The dough mixer needs to be manually stopped at regular intervals to take out a small portion of the dough to observe whether the dough has reached the optimal kneading state. In the optimal state, the dough has a smooth surface and a soft feel, and the dough can be pulled into a uniform film. If it does not reach the optimal state, the dough mixer needs to be manually started again to continue kneading the dough. During each kneading process, the dough needs to be checked 2-6 times. The process is cumbersome, has high requirements for operators, and is labor-intensive. Summary of the invention

[0014] S2, the acquisition component collects the effective power P of the drive motor in real time t data, and the effective power P t The data is transmitted to the smoothing and denoising module of the controller in real time. After the data is processed by the smoothing and denoising module, the data recording module displays the effective power curve in the form of a continuous and smooth image to judge P t-1 <P t If the result is yes, proceed to the next step. If the result is no, repeat this step.

[0015] S3, when the gluten tension of the dough reaches the maximum, the resistance of the moving needle is the largest, and the effective power of the driving motor is in a suitable state, that is, the effective power is stable at the maximum value for a period of time.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown, the digital dough mixer of embodiment 1 of the present invention includes a collection component 1, a controller, a machine base 8, a bowl body 7, a stirring component and a driving device.

[0031] Among them, the stirring component is arranged on the machine base 8. In this embodiment, the stirring component includes a moving needle 10 arranged on the dough kneading head 2, and a fixed needle 11 arranged on the bowl body 7. The rotation of the dough kneading head 2 drives the moving needle 10 to rotate relative to the fixed needle 11 to knead the dough.

[0032] Specifically, the driving device drives the stirring assembly to rotate, and the driving device includes a transmission assembly 12 connected to the stirring assembly, and a driving motor 3 driving the transmission assembly 12 to move.

[0033] The acquisition component 1 acquires effective power data of the driving device. In order to reduce the influence of other power consumption on the effective power, the acquisition component 1 is connected to the driving motor 3 to acquire the effective current and effective voltage of the driving motor 3 .

[0034] At the same time, the controller is connected to the acquisition component 1 and is used to receive the data collected by the acquisition component 1. The controller controls the driving device to stop working when the effective power of the driving device is in a suitable state. The controller includes a smoothing and denoising module 4 connected to the acquisition component 1, a data recording module 5 connected to the smoothing and denoising module 4, and a control unit 6 connected to the data recording module 5 and the driving device for controlling the action of the driving device. The smoothing and denoising module 4 is equipped with data processing software, which can perform smoothing and denoising on the data, and finally display the change trend of the effective power with a continuous and smooth curve.

[0035] In this embodiment, the suitable state is that the effective power is stably at the maximum value for a period of time, that is, the smooth curve is at the maximum effective power for a period of time, and after the period of time, the effective power will decrease. The data recording module 5 records the data and displays the curve graph processed by the smoothing and denoising module 4 with time as the horizontal axis and the effective power as the vertical axis. After testing, according to different types of flour, preferably, the period of time is between 0s and 120s.

[0036] Specifically, the bowl body 7 is arranged opposite to the dough kneading head 2 of the stirring assembly, the bowl body 7 is connected to the moving mechanism 9, the moving mechanism 9 is arranged on the base 8, and the moving mechanism 9 can move toward or away from the stirring assembly.

[0037] As a convertible implementation, the collection component 1 collects the effective power of the dough mixer, and when the effective power of the dough mixer is in a suitable state, the controller controls the dough mixer to stop working. However, there are many factors that affect the effective power of the dough mixer, and there is a certain error in judging whether the dough mixer is in the best state of dough quality by collecting the effective power of the dough mixer.

[0038] The use process of the digital dough mixer of Example 1 of the present invention is as follows:

[0039] First, add appropriate amount of flour and water into the bowl body 7, fix the bowl body 7 on the moving mechanism 9, move the moving mechanism 9 upward, make the bowl body 7 contact with the dough head 2, start the drive motor 3, and the moving needle 10 on the dough head 2 starts to stir the flour in the bowl body 7, and the dough mixer starts to work; the acquisition component 1 collects the effective current and effective voltage of the drive motor 3, that is, collects the effective power data of the drive motor 3, and transmits the effective power data to the smoothing and denoising module 4 of the controller in real time. After the data is smoothed and denoised by the smoothing and denoising module 4, the data recording module 5 displays the effective power curve in the form of a continuous and smooth image; when the peak value of the effective power curve in the data recording module 5 reaches the maximum value, it indicates that the dough has reached the best dough state at this time, the control unit 6 acts on the drive motor 3, the drive motor 3 stops running, the dough mixer stops working, and the dough mixing ends; then the bowl body 7 is removed from the moving structure, the dough in the bowl body 7 is taken out, and the dough in the best dough state is obtained, and finally the dough mixer is cleaned.

[0040] In this embodiment, initialization is usually performed each time the computer is powered on.

[0041] When the gluten tension of the dough reaches the maximum, the dough has the maximum ductility and elasticity, and the dough is in the best dough state. During the dough mixing process, the resistance of the moving needle 10 on the dough head 2 is opposite to the direction of rotation of the moving needle 10, and the effective power of the drive motor 3 is positively correlated with the resistance of the moving needle 10. When the gluten tension of the dough reaches the maximum, the resistance of the moving needle 10 is the maximum, the effective power of the drive motor 3 is the maximum, and the effective power curve in the data recording module 5 reaches the maximum value. The dough will remain in this state for a period of time. If it continues to be stirred, the gluten tissue structure will be destroyed, the resistance of the moving needle 10 will decrease, and the effective power curve will decrease. Therefore, when the dough is in the stable time, the control unit 6 acts on the drive motor 3, the drive motor 3 stops running, the dough mixer stops working, and the dough mixing ends, and the dough in the best dough state can be obtained. The dough mixer automatically determines the best dough mixing state, and the operator does not need to stop / start the dough mixer many times and repeatedly observe the state of the dough to determine whether the dough has reached the best dough mixing state. This can reduce the labor intensity and workload of the operator, lower the requirements for the operator, improve work efficiency, and at the same time, obtain dough in the best dough mixing state.

[0042] Example 2

[0043] like Figure 3 As shown, the working method of the digital dough mixer of embodiment 2 of the present invention, using the digital dough mixer, comprises the following steps:

[0044] S1, add appropriate amount of flour and water into the bowl body 7, fix the bowl body 7 on the moving mechanism 9, move the moving mechanism 9 upward, make the bowl body 7 contact with the dough mixing head 2, start the driving motor 3, the moving needle 10 on the dough mixing head 2 starts to stir the flour in the bowl body 7, and the dough mixing machine starts to work;

[0045] S2, the acquisition component collects the effective power P of the drive motor 3 in real time t data, and the effective power P t The data is transmitted to the smoothing and denoising module 4 of the controller in real time. After the data is processed by the smoothing and denoising module 4, the data recording module 5 displays the effective power curve in the form of a continuous smooth image to judge P t-1 <P t If the result is yes, proceed to the next step. If the result is no, repeat this step.

[0046] S3, when the gluten tension of the dough reaches the maximum, the resistance of the moving needle 10 is the maximum, and the effective power of the driving motor 3 is in a suitable state, that is, the effective power is stable at the maximum value for a period of time. At this time, the peak value of the effective power curve in the data recording module 5 reaches the maximum value, indicating that the dough has reached the best dough state at this time, and P is judged. t+n =P t If the result is yes, proceed to the next step. If the result is no, repeat the previous step. n is a set period of time, which is between 0s and 120s.

[0047] S4, judge P t+n+1 <P t+n When the result is yes, the control unit 6 acts on the drive motor 3, the drive motor 3 stops running, the dough mixer stops working, the dough kneading is completed, and the dough in the best dough kneading state can be obtained. Then the bowl 7 is removed from the mobile structure 9 and the dough in the bowl 7 is taken out; when the result is no, repeat the previous step.

[0048] Among them, P t is the effective power at time t, P t-1 is the effective power at time t-1, P t+n is the effective power at time t+n, n is the preset value, P t+n+1 is the effective power at t+n+1.

[0049] There are many factors that affect the effective power of the dough mixer. Directly collecting the effective power of the dough mixer will result in a certain error. Real-time collection of the effective power of the drive motor 3 that directly drives the stirring assembly will result in a smaller error.

[0050] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
