[0002] A farinograph is a core instrument for detecting the rheological properties of flour. Wheat flour milled in a test mill is mixed with water in the farinograph. As the dough forms and decays, its consistency changes continuously. A force gauge and recorder measure and automatically record the resistance changes corresponding to the consistency during dough kneading. Based on the amount of water added and the farinograph curve recording the kneading performance, the water absorption of wheat flour is calculated, and evaluation indicators such as dough formation time, stability time, and weakening degree are evaluated. The physical properties of wheat are comprehensively evaluated, providing key data support for wheat milling processes and baking quality.

[0020] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: A cleaning device for a farinograph mixer includes a cleaning tank 1, a collection tank 23, a kneading bowl mounting mechanism, a cleaning mechanism, a stirring blade mounting mechanism, an electrical control system, a drying device, and a filtering mechanism. The components work together to achieve automatic cleaning, drying, and waste filtration of the kneading bowl 2 and stirring blade 7 of the farinograph mixer.

[0022] like Figure 3 and Figure 4As shown, the cleaning tank 1, collection tank 23, and rear protective shell 38 form the basic mounting carrier of this cleaning device. To ensure the stability of the entire device, shock-absorbing feet are provided at the bottom of the cleaning tank 1, collection tank 23, and rear protective shell 38. Simultaneously, both the cleaning tank 1 and collection tank 23 have doors on their front sides, each equipped with an observation glass. Workers can observe the internal cleaning and drying process in real time through the observation glass of the cleaning tank 1, and check the residue collection status through the observation glass of the collection tank 23, facilitating timely detection and handling of problems. The cleaning tank 1, as the core cleaning area, has a kneading bowl mounting mechanism at its upper end. This mechanism securely mounts the kneading bowl 2 to be cleaned in an inverted manner, preventing it from falling off or shaking during the cleaning process and ensuring the cleaning effect. In some other exemplary embodiments, the rear protective shell 38 not only provides protection but also has a partition near its lower end, forming a wastewater collection pool between it and the rear wall of the collection tank 23. This pool can be used to collect wastewater from the bottom of the cleaning tank 1 and discharge it through a drain connector and drain pipe.

[0023] like Figure 3 , Figure 4 and Figure 7 As shown, the kneading bowl mounting mechanism includes a mounting plate 9, mounting bolts 10, plug-in posts 11, sealing plug-in plates 12, and sealing strips 13. The mounting plate 9 is fixed to the upper end face of the washing box 1. A water passage hole 3 is formed through the top wall of the washing box 1. This water passage hole 3 is connected to the kneading groove of the kneading bowl 2 after it is installed upside down, providing a channel for the flow of washing water and ensuring that the washing water can smoothly enter the kneading groove. To achieve detachable installation of the kneading bowl 2 and facilitate subsequent disassembly and maintenance, the mounting plate 9 has threaded holes corresponding to the ear plates of the kneading bowl 2. The screw of the mounting bolt 10 passes through the ear plates of the kneading bowl 2 and engages with the threaded holes, so that the kneading bowl 2 is detachably and sealed upside down and fixed to the mounting plate 9. Considering that the side of the kneading bowl 2 has an opening, in order to prevent the washing water from overflowing from the opening, two plug-in posts 11 are also fixed on the mounting plate 9. The two plug-in posts 11 are located on the same side of the opening of the side of the kneading bowl 2, and the side closest to each other has a plug-in groove. The two ends of the sealing plug-in plate 12 can be inserted into the plug-in grooves of the two plug-in posts 11 respectively. A hollow sealing strip 13 is pasted on the sealing plug-in plate 12. When the sealing plug-in plate 12 is fully inserted into the plug-in groove, the sealing strip 13 is pressed between the sealing plug-in plate 12 and the opening of the side of the kneading bowl 2, forming a reliable waterproof sealing structure to prevent the washing water from overflowing and polluting the environment and affecting the normal operation of the device.

[0024] like Figure 4 , Figure 5 and Figure 8As shown, the cleaning mechanism mainly consists of a water pump 4, a water supply pipe 5, and a rotating nozzle 6. The rotating nozzle 6 is connected to the water pump 4 via the water supply pipe 5. The water pump 4 draws and pressurizes the cleaning water before supplying it to the rotating nozzle 6 via the water supply pipe 5. The rotating nozzle 6 is a self-rotating nozzle that can rotate 360° to spray water. The rotating nozzle 6 is located inside the cleaning tank 1 and directly below the water passage hole 3. During operation, the rotating nozzle 6 can rotate while spraying water, spraying high-pressure water through the water passage hole 3 into the kneading trough of the kneading bowl 2, thus achieving a thorough rinse of the inner wall of the kneading trough. Figure 1 As shown, the kneading bowl 2 has two kneading troughs arranged side by side. Correspondingly, the cleaning mechanism is also equipped with two rotating nozzles 6. The two rotating nozzles 6 are arranged one-to-one directly below the two kneading troughs to ensure that the two kneading troughs can be thoroughly cleaned at the same time.

[0025] like Figure 4 and Figure 5 As shown, the stirring blade mounting mechanism includes a drive assembly and two rotating shaft seats 8. The two rotating shaft seats 8 are used to mount two stirring blades 7, and the two stirring blades 7 are positioned directly below two rotating nozzles 6, allowing the high-pressure water sprayed from the rotating nozzles 6 to simultaneously rinse the surface of the stirring blades 7, improving cleaning efficiency. The drive assembly drives the rotating shaft seats 8 to rotate, thereby causing the stirring blades 7 to rotate, thus achieving thorough cleaning of the stirring blades 7. Specifically, the drive assembly includes a first motor 14, a driving bevel gear 15, a driven bevel gear 16, two pulleys 17, and a first transmission belt 18, all housed in the rear protective housing 38. The driving bevel gear 15 is mounted on the shaft of the first motor 14, and the driven bevel gear 16 meshes with and is connected to the driving bevel gear 15. The driven bevel gear 16 is mounted on one of the rotating shaft seats 8. The two pulleys 17 are mounted on the two rotating shaft seats 8 in a corresponding manner. The first transmission belt 18 is wound around the two pulleys 17. During operation, the first motor 14 starts and drives the driving bevel gear 15 to rotate. The driving bevel gear 15 drives the driven bevel gear 16 to rotate, which in turn drives one of the rotating shaft seats 8 to rotate. This rotating shaft seat 8 drives the other rotating shaft seat 8 to rotate synchronously through the pulleys 17 and the first transmission belt 18, ultimately achieving synchronous rotation of the two stirring blades 7. Combined with the high-pressure water rinsing of the rotating nozzle 6, this ensures that the dough residue on the surface of the stirring blades 7 can be thoroughly cleaned.

[0026] like Figure 4 , Figure 5 and Figure 8As shown, to achieve the drying function after cleaning, this cleaning device is also equipped with a drying device, which includes a hot air blower 19, an air supply pipe 20, and an air outlet 21. The air outlet 21 is connected to the hot air blower 19 through the air supply pipe 20. The air outlet 21 is located in the cleaning chamber 1 and between the two rotating nozzles 6. The air outlet 21 is cylindrical with a sealed end and multiple air outlet holes on its wall. After cleaning, the hot air blower 19 is started, and the generated hot air is delivered to the air outlet 21 through the air supply pipe 20. The air outlet 21 blows the hot air evenly onto the kneading groove and stirring blades 7 of the kneading bowl 2, achieving rapid drying of both.

[0027] like Figure 4 , Figure 6 and Figure 8 As shown, in order to treat the waste liquid containing dough residue generated during the washing process and avoid direct discharge that could cause sewer blockage and odor, this washing device is also equipped with a filtration mechanism. The filtration mechanism mainly consists of three layers of screens 22, a collection box 23, a residue passage hole 24, a residue basket 25, a guide plate 26, a vibration drive assembly, and a tensioning wheel assembly. The three layers of screens 22 are arranged sequentially from top to bottom inside the washing box 1, with each layer of screens 22 inclined in the same direction. The mesh size of each layer of screens 22 gradually decreases from top to bottom. This layered arrangement... The filtration structure plays a crucial role in removing dough residue as much as possible. If only the top layer of large-mesh filter screen is used, some fine residue will fall directly into the waste liquid and cause foul odors when discharged into the sewer. If only the bottom layer of small-mesh filter screen is used, larger particles of residue will clog the mesh, leading to poor drainage and affecting the washing effect. The three-layer screen 22 design allows for the thorough filtration of dough residue by filtering larger particles through the upper large mesh, medium particles through the middle medium mesh, and fine particles through the bottom small mesh. The collection box 23 is located on one side of the washing box 1, at the lower end of the screen 22. A slag passage hole 24 penetrates the wall between the washing box 1 and the collection box 23. A guide plate 26 is inclined and passes through the slag passage hole 24, with its higher end below the lower end of the bottom screen 22 and its lower end extending into the collection box 23 and above the residue basket 25. This guide plate helps guide the residue sliding off the screen 22 into the residue basket 25. The residue basket 25 is located in the collection box 23 and collects the filtered dough residue. The waste residue in the basket 25 flows to the bottom of the collection box 23 and is eventually discharged into the sewer, achieving separation of waste liquid and residue, preventing sewer blockage and odor generation.

[0028] like Figure 5 , Figure 9 and Figure 10As shown, in order to prevent the screen 22 from being clogged by residue during the filtration process and to ensure smooth filtration, the filtration mechanism is also equipped with a vibration drive component. This vibration drive component is used to drive the screen 22 to vibrate, so that the residue on the screen 22 can slide smoothly onto the guide plate 26. In this embodiment, each layer of screen 22 is connected to two connecting rods 37. The connecting rods 37 are arranged sequentially at intervals along the inclined direction of the screen 22. The vibration drive assembly includes connecting rods 37, rotating wheels 27, a second motor 28, a driving pulley 29, a driven shaft 30, a driven pulley 31, and a second transmission belt 32. The rotating wheels 27 are connected to the connecting rods 37 in a one-to-one correspondence, and the connecting rods 37 are eccentrically mounted on the rotating wheels 27. The driven shafts 30 are located on the outside of the cleaning tank 1 and are horizontally rotatably mounted on the rear wall of the cleaning tank 1. The number of driven shafts 30 is the same as that of the rotating wheels 27. The rotating wheels 27 are mounted on the driven shafts 30 in a one-to-one correspondence. The driven pulleys 31 are mounted on each driven shaft 30 in a one-to-one correspondence. The second transmission belt 32 connects the driving pulley 29 and each driven pulley 31. The driving pulley 29 is mounted on the shaft of the second motor 28. During operation, the second motor 28 starts and drives the drive pulley 29 to rotate. The drive pulley 29 drives each driven pulley 31 to rotate synchronously through the second transmission belt 32. The driven pulleys 31 drive the driven shaft 30 to rotate, which in turn drives the rotating wheel 27 to rotate. Since the connecting rod 37 is eccentrically mounted on the rotating wheel 27, the rotating wheel 27 will drive the connecting rod 37 to reciprocate when it rotates, which will cause the screen 22 to vibrate, thereby achieving self-cleaning of the screen 22 and preventing the mesh from clogging.

[0029] like Figure 5 and Figure 9 As shown, to ensure the transmission stability of the second transmission belt 32 and prevent slippage or loosening during operation, the filter mechanism is also equipped with a tensioning wheel assembly. This tensioning wheel assembly includes a mounting base 33, a tensioning shaft 34, a tensioning wheel 35, and an adjusting bolt 36. The mounting base 33 is fixedly mounted on the rear wall of the cleaning tank 1. The tensioning shaft 34 is slidably mounted in the mounting base 33. The tensioning wheel 35 is rotatably mounted on the tensioning shaft 34 and presses against the second transmission belt 32 to adjust the tension of the second transmission belt 32. The adjusting bolt 36 is threaded onto the mounting base 33, with its screw end abutting against the tensioning shaft 34. Operators can rotate the adjusting bolt 36 to drive the tensioning shaft 34 to slide within the mounting base 33, thereby adjusting the pressure of the tensioning wheel 35 on the second transmission belt 32, achieving flexible adjustment of the tension of the second transmission belt 32 and ensuring a stable and reliable transmission process.

[0030] The electrical control system of this cleaning device controls the operating status of each component, ensuring the orderly progress of the entire cleaning, drying, and filtration process. This system includes a touchscreen and a controller. The touchscreen is electrically connected to the controller. The water pump 4, drive assembly (first motor 14), hot air blower 19, and second motor 28 are all electrically connected to the controller and uniformly controlled by it. The touchscreen features a one-button cleaning module and a parameter setting module. The one-button cleaning module displays a one-button cleaning icon on the touchscreen; operators can simply click this icon to issue an automatic cleaning command. The parameter setting module allows operators to set the cleaning water pressure, cleaning duration, and output speed of the drive assembly according to actual cleaning needs. It also allows setting the operating time of the hot air blower 19 and the speed of the second motor 28. The controller is configured to respond to touch signals from the one-button cleaning icon, simultaneously activating water pump 4, drive assembly, hot air blower 19, and second motor 28. It also adjusts the output power of water pump 4 according to the water pressure value set by the parameter setting module to ensure the cleaning water pressure meets requirements. Furthermore, it controls the running time of water pump 4, drive assembly, hot air blower 19, and second motor 28 according to a set duration value, automating the cleaning, drying, and filtration processes. The controller also adjusts the output speed of the drive assembly according to a set rotation speed value, thereby adjusting the rotation speed of the stirring blades 7. Finally, it adjusts the operating speed of the second motor 28 according to a set speed value, ensuring the vibration frequency of the vibration drive assembly meets filtration requirements. This coordinated operation of all components enhances the automation level and cleaning effect of the device.

[0031] In summary, this invention, by setting up a cleaning box 1, a collection box 23, a kneading bowl installation mechanism, a cleaning mechanism, a stirring blade installation mechanism, an electrical control system, a drying device, and a filtration mechanism, with each component working together, can achieve automatic cleaning, drying, and waste slag filtration of the kneading bowl 2 and stirring blade 7 of the powder mixer. This effectively solves the problems of low efficiency and high labor intensity of manual cleaning, and the easy clogging of sewers and generation of odors by waste slag discharge.
