Description

Technical Field

[0001] This invention relates to the field of flour processing, and in particular to a fine sieving device for processing tea flour and its working method. Background Technology

[0002] Currently, many food products are developed using tea as a raw material. The gelatinization characteristics of flour are an important factor affecting its processing quality. Adding a certain amount of tea powder can improve the shear resistance and stirring resistance of flour gelatinization. The peak viscosity, trough viscosity, final viscosity, recovery value, and gelatinization time of flour decrease with the addition of tea powder. When the added tea content is 2%-5%, the flour has the best agglomeration effect. The production method of tea flour is to grind the finished tea and flour separately, and then mix the ground tea powder and flour. In order to ensure the quality of subsequent flour products, the flour and tea need to be sieved during the mixing process to ensure the fine powder.

[0003] However, when sieving tea and flour, since tea and wheat are different substances, the mesh size they pass through after sieving will also differ. Using sieves with mesh sizes that are too large or too small cannot guarantee the quality of either the tea or the flour. Furthermore, when mixing tea and flour, the tea leaves need to be pulverized into different mesh sizes according to the shape of the finished product. Separate sieving processes are time-consuming and labor-intensive. It is advisable to ensure that the tea powder content is between 2% and 5%. If both are processed together, it becomes difficult to quantitatively control the quantity, and the quality of either the tea or the flour cannot be guaranteed.

[0004] Therefore, we propose a fine sieving device for tea flour processing and its working method. Summary of the Invention

[0005] The main objective of this invention is to provide a fine sieving device and its working method for processing tea flour, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A fine sieving device for tea flour processing and its working method include a tea grinding box and a flour grinding box. A support base is installed inside the tea grinding box. A drive roller is installed at the bottom of the support base. A support column is installed on one side of the top of the support base. A connecting column is installed at the top of the support column. A first push rod motor is installed inside the connecting column. A connecting rod is installed at the bottom of the first push rod motor. A fixed shaft is installed in the middle of the connecting rod. An adjusting roller is installed on the surface of the fixed shaft. A positioning block is installed inside the adjusting roller. The two sides of the support column... A locking block is installed on the side, and the surface of the locking block has an inlet for easy feeding of finished tea leaves. A connecting pipe is installed at the bottom of the two locking blocks to facilitate the collection of finished tea leaves. The connection between the connecting pipe and the locking block is arc-shaped, which facilitates the sliding of tea leaves and prevents them from accumulating in the arc-shaped pipe. An feeding rod is installed at the bottom of the connecting pipe to feed the collected tea leaves. The bottom of the feeding rod is arc-shaped to facilitate the feeding of tea leaves to fit the contact point between the active roller and the adjusting roller.

[0008] A further improvement of the present invention is that a first collection box is installed on one side of the support base, a filter plate is installed at the connection between the collection box and the support base, the other end of the filter plate is connected to the bottom of the connecting rod, a plurality of slots are opened on the surface of the filter plate, a spring is installed on one side of the slot, a baffle is installed on the other end of the spring, and a gap is left between the baffle and the other end of the slot. The grinding and screening of the finished tea can be achieved by adjusting the filter plate in conjunction with the provided active roller and adjusting roller.

[0009] A further improvement of the present invention is that the flour grinding box has an inlet, the flour grinding box is equipped with corresponding grinding rollers, a vibrator is installed in the middle of the inner wall of the flour grinding box, a screen is installed in the middle of the two vibrators, and a second collection box is installed at the bottom of the flour grinding box. The screen and the vibrator can vibrate and sieve the ground flour, and the sieved flour can be collected through the second collection box.

[0010] A further improvement of the present invention is that the bottom of the first collection box and the bottom of the second collection box are both funnel-shaped. A first collection tube is installed at the bottom of the first collection box, and a second collection tube is installed at the bottom of the second collection box. An opening is provided at the bottom of both the first and second collection tubes. A support rod is installed through the surface of the opening, and a blocking plug is installed at the top of the support rod. The top of the blocking plug is arc-shaped. The first collection tube can collect tea powder, and the second collection tube can collect flour. The opening and the blocking plug cooperate to facilitate the falling of tea powder or flour from the first and second collection tubes or to stop the falling of tea powder or flour.

[0011] A further improvement of the present invention is that baffles are installed on both sides of the bottom of the first and second collecting tubes, and a first and second storage cylinders are respectively installed between the two baffles. The inclination angle of the side of the first storage cylinder is smaller than that of the side of the second storage cylinder. Two first photosensitive films are installed on the inner wall of the first storage cylinder, and a second photosensitive film is installed inside the second storage cylinder. The mass of material stored between the position of the first photosensitive film and the bottom of the first storage cylinder is 50g, and the mass of material stored between the position of the second photosensitive film and the bottom of the second storage cylinder is 950g. By using the first and second storage cylinders, the first and second photosensitive films, the quantities of tea powder and flour can be determined, maintaining a good ratio between tea powder and flour, which is beneficial to the flour gelatinization characteristics in subsequent tea flour processing.

[0012] A further improvement of the present invention is that a seepage port is installed at the bottom of the support rod. During the up-and-down movement of the support rod driven by the second push rod motor, flour or tea powder can pass through the seepage port, and the tea powder or flour at both ends of the support rod are kept at the same horizontal line. A guide block is installed at the bottom of the inner end of the first storage cylinder and the bottom of the inner end of the second storage cylinder. A second push rod motor is provided at the bottom of the outer wall of the first storage cylinder and the bottom of the outer wall of the second storage cylinder. The top of the second push rod motor and the bottom of the support rod are connected to each other.

[0013] A further improvement of the present invention is that the guide block is composed of two trapezoidal bottoms connected together, the inclination angle of the top of the guide block is greater than the inclination angle of the bottom, and a gate valve is installed at the bottom of the guide block. The guide block at the top can effectively allow the material to slide down, and the guide block at the bottom can allow the material guide block to slide down from the side and inside the gate valve after the gate valve is opened.

[0014] A further improvement of the present invention is that a proportioning box is installed at the bottom of the tea grinding box and the flour grinding box, a rotating motor is installed inside the proportioning box, a stirring rod is installed at one end of the rotating motor, and a discharge port is installed on the surface of the proportioning box to uniformly mix a certain proportion of tea powder and flour, thereby ensuring the gelatinization characteristics of the flour in the subsequent dough formation.

[0015] The device operates as follows:

[0016] Step 1: Adjust the extension length of the first push rod motor according to the required tea powder sieve mesh size, and put the finished tea into the inlet.

[0017] Step 2: Turn on the equipment switch and put the finished wheat into the feed inlet;

[0018] Step 3: After a period of time, the mixture of tea powder and flour will flow out from the outlet, and you can collect it.

[0019] Compared with existing technologies, this method, through the use of a first push rod motor, adjusting rollers, and a filter plate, can control the diameter of tea powder and simultaneously control the screening of tea powder of that diameter. This avoids the need for two separate devices for grinding and screening tea powder, as is traditional methods. When a larger diameter tea powder is required (i.e., a smaller sieve mesh), the push rod of the first push rod motor moves upward, increasing the distance between the active roller and the adjusting roller's positioning block. This results in a larger diameter tea powder ground by the active and adjusting rollers. Simultaneously, as the push rod motor drives the adjusting roller upward, it also drives the filter plate upward. The filter plate rotates upward relative to the support base, causing the gravitational force of the baffle to compress the spring, increasing the distance between the baffle and the slotted side, thus filtering tea powder with a smaller sieve mesh. When a smaller diameter tea powder is required (i.e., a larger sieve mesh), the first push rod motor... The push rod of the push rod motor moves downward, reducing the distance between the positioning block of the active roller and the adjusting roller. This results in a smaller diameter tea powder ground by the active and adjusting rollers. Simultaneously, as the push rod motor drives the adjusting roller downward, it also drives the filter plate downward. The filter plate rotates upward relative to the support base, amplifying the force of gravity on the spring. The reduced distance between the baffle and the slotted side allows for the filtration of tea powder with a larger mesh size. The finished tea leaves are then placed inside the locking block. The tea leaves slide from the locking block to the connecting pipe and fall from the bottom of the feeding rod between the active and adjusting rollers for grinding. The ground tea powder falls into the first collection box. This integrated grinding and sieving process reduces the number of devices involved in the tea grinding process, saves floor space, and is simple to operate, demonstrating a certain level of innovation.

[0020] Compared with existing technologies, the first and second collection tubes can collect tea powder and flour respectively, and the first and second photosensitive films can determine the volume of tea powder and flour respectively, facilitating the subsequent ratio of tea powder and flour. This ensures that tea accounts for 5% of the total tea powder and flour, maintaining the gelatinization characteristics of the tea powder after it clumps together. Tea powder inside the first collection box falls into the first collection tube, and flour inside the second collection box falls into the second collection tube, and then falls through the opening between the two baffles. As the tea powder and flour accumulate, they block the two first and second photosensitive films respectively. When the first or second photosensitive film is completely blocked, it indicates that the weight of the tea powder or flour has reached the specified weight. The second push rod motor is then controlled to move downwards. At this time, the second push rod motor can drive the support rod to move downwards, thereby blocking the opening and preventing the tea powder and flour from falling. Then, the two gate valves are opened, allowing the tea powder or flour to fall through the gap and collect in the mixing box. Attached Figure Description

[0032] In this embodiment, a first collection box 21 is installed on one side of the support base 3. A filter plate 20 is installed at the connection between the collection box and the support base 3. The other end of the filter plate 20 is connected to the bottom of the connecting rod 18.

A gap is left between the baffle 24 and the other end of the slot 22. The grinding and screening of the finished tea can be achieved by adjusting the filter plate 20 in conjunction with the provided active roller 15 and adjusting roller 16.

[0033] In this embodiment, the flour grinding box 2 has an inlet 8 inside, and grinding rollers 25 with corresponding positions are installed inside the flour grinding box 2. A vibrator 27 is installed in the middle of the inner wall of the flour grinding box 2, and a screen 26 is installed in the middle of the two vibrators 27. A second collection box 28 is installed at the bottom of the flour grinding box 2. The screen 26 and the vibrator 27 can vibrate and sieve the ground flour, and the sieved flour can be collected through the second collection box 28.

[0034] In this embodiment, the bottom of the first collection box 21 and the bottom of the second collection box 28 are both funnel-shaped. A first collection pipe 29 is installed at the bottom of the first collection box 21, and a second collection pipe 30 is installed at the bottom of the second collection box 28. An opening 32 is provided at the bottom of both the first collection pipe 29 and the second collection pipe 30. A support rod 33 is installed through the surface of the opening 32, and a blocking plug 31 is installed at the top of the support rod 33. The top of the blocking plug 31 is arc-shaped. The first collection pipe 29 can collect tea powder, and the second collection pipe 30 can collect flour. The opening 32 and the blocking plug 31 cooperate with each other to facilitate the tea powder or flour to fall from the first collection pipe 29 and the second collection pipe 30 or to stop the falling.

[0035] In this embodiment, baffles 24 are installed on both sides of the bottom of the first collection tube 29 and the second collection tube 30. A first storage cylinder 34 and a second storage cylinder 36 are respectively installed between the two baffles 24. The inclination angle of the side of the first storage cylinder 34 is smaller than that of the side of the second storage cylinder 36. Two first photosensitive films 35 are installed on the inner wall of the first storage cylinder 34. A second photosensitive film 37 is installed inside the second storage cylinder 36. The mass of material stored between the position of the first photosensitive film 35 and the bottom of the first storage cylinder 34 is 50g, and the mass of material stored between the position of the second photosensitive film 37 and the bottom of the second storage cylinder 36 is 950g. The quantities of tea powder and flour can be determined by the first storage cylinder 34, the second storage cylinder 36, the first photosensitive film 35, and the second photosensitive film 37, maintaining a good ratio between tea powder and flour, which is beneficial to the gelatinization characteristics of flour in subsequent tea flour processing.

[0036] In this embodiment, a seepage port 38 is installed at the bottom of the support rod 33. During the process of the second push rod motor 39 driving the support rod 33 to move up and down, flour or tea powder can pass through the seepage port 38. The tea powder or flour at both ends of the support rod 33 are kept at the same horizontal line.

[0038] In this embodiment, a mixing box 10 is installed at the bottom of the tea grinding box 1 and the flour grinding box 2. A rotating motor 11 is installed inside the mixing box 10. A stirring rod is installed at one end of the rotating motor 11.

[0041] Step 2: Turn on the equipment switch and put the finished wheat into the feed inlet 8;

[0042] Step 3: After a period of time, the mixture of tea powder and flour will flow out from outlet 12, and can be collected.

[0043] Example 2

[0044] like Figure 1-6 As shown, a fine sieving device for tea flour processing and its working method include a tea grinding box 1 and a flour grinding box 2. A support base 3 is installed inside the tea grinding box 1. A drive roller 15 is installed at the bottom of the support base 3. A support column 4 is installed on one side of the top of the support base 3. A connecting column 5 is installed at the top of the support column 4. A first push rod motor 14 is installed inside the connecting column 5. A connecting rod 18 is installed at the bottom of the first push rod motor 14. A fixed shaft 17 is installed in the middle of the connecting rod 18. An adjusting roller 16 is installed on the surface of the fixed shaft 17. A positioning block 19 is installed inside the adjusting roller 16. The column 4 is equipped with locking blocks 6 on both sides. The surface of the locking blocks 6 is provided with an inlet 7, which facilitates the feeding of finished tea leaves. The bottom of the two locking blocks 6 is equipped with a connecting pipe 9, which facilitates the collection of finished tea leaves. The connection between the connecting pipe 9 and the locking blocks 6 is arc-shaped, which facilitates the sliding of tea leaves and prevents them from accumulating in the arc-shaped pipe. The bottom of the connecting pipe 9 is equipped with an feeding rod 13, which can feed the collected tea leaves. The bottom of the feeding rod 13 is arc-shaped, which facilitates the feeding of tea leaves to the contact point between the active roller 15 and the adjusting roller 16.

[0045] In this embodiment, a first collection box 21 is installed on one side of the support base 3. A filter plate 20 is installed at the connection between the collection box and the support base 3. The other end of the filter plate 20 is connected to the bottom of the connecting rod 18. Several slots 22 are opened on the surface of the filter plate 20. A spring 23 is installed on one side of the slot 22. A baffle 24 is installed on the other end of the spring 23. A gap is left between the baffle 24 and the other end of the slot 22. The grinding and screening of the finished tea can be achieved by adjusting the filter plate 20 in conjunction with the provided active roller 15 and adjusting roller 16.

[0046] In this embodiment, the flour grinding box 2 has an inlet 8 inside, and grinding rollers 25 with corresponding positions are installed inside the flour grinding box 2. A vibrator 27 is installed in the middle of the inner wall of the flour grinding box 2, and a screen 26 is installed in the middle of the two vibrators 27. A second collection box 28 is installed at the bottom of the flour grinding box 2. The screen 26 and the vibrator 27 can vibrate and sieve the ground flour, and the sieved flour can be collected through the second collection box 28.

[0047] In this embodiment, the device operates as follows:

[0048] Step 1: Adjust the extension length of the first push rod motor 14 according to the required tea powder sieve mesh size, and put the finished tea into the inlet 7.

[0049] Step 2: Turn on the equipment switch and put the finished wheat into the feed inlet 8;

[0050] Step 3: After a period of time, the mixture of tea powder and flour will flow out from outlet 12, and can be collected.

[0051] This embodiment enables the control of tea powder diameter via a first push rod motor 14, adjusting roller 16, and filter plate 20. It also allows for the control of tea powder selection based on diameter, avoiding the need for two separate devices for grinding and sieving tea powder as in traditional methods. When a larger diameter tea powder is required (i.e., a smaller sieve mesh), the push rod of the first push rod motor 14 moves upward, increasing the distance between the active roller 15 and the positioning block 19 of the adjusting roller 16. This results in a larger diameter tea powder ground by the active roller 15 and adjusting roller 16. Simultaneously, as the push rod motor drives the adjusting roller 16 upward, it also drives the filter plate 20 upward. The filter plate 20 rotates upward relative to the side of the support base 3, causing the gravitational force of the baffle 24 to compress the spring 23. This increases the distance between the baffle 24 and the side of the slot 22, filtering tea powder with a smaller sieve mesh. When a smaller diameter tea powder is required (i.e., a larger sieve mesh), the first push rod... When the push rod of motor 14 moves downward, the distance between the active roller 15 and the positioning block 19 of the adjusting roller 16 is reduced. This results in a smaller diameter tea powder ground by the active roller 15 and the adjusting roller 16. Simultaneously, as the push rod motor drives the adjusting roller 16 downward, it also drives the filter plate 20 downward. The filter plate 20 and the side of the support base 3 rotate upward. At this time, the component of gravity of the baffle 24 amplifies the force on the spring 23. The side of the baffle 24 and the slotted 22 rotate upward. The reduced distance allows for the filtering of tea powder with a larger mesh size. The finished tea is placed inside the locking block 6. The finished tea is then fed into the locking block 6, where it slides down to the connecting pipe 9 and falls from the bottom of the feeding rod 13 between the active roller 15 and the adjusting roller 16 for grinding. The ground tea powder falls into the first collection box 21. By integrating grinding and sieving, the number of devices in the tea grinding process is reduced, saving floor space. The operation is simple and innovative.

[0052] Example 2

[0053] like Figure 1-6As shown, a fine sieving device for tea flour processing and its working method include a tea grinding box 1 and a flour grinding box 2. A support base 3 is installed inside the tea grinding box 1. A drive roller 15 is installed at the bottom of the support base 3. A support column 4 is installed on one side of the top of the support base 3. A connecting column 5 is installed at the top of the support column 4. A first push rod motor 14 is installed inside the connecting column 5. A connecting rod 18 is installed at the bottom of the first push rod motor 14. A fixed shaft 17 is installed in the middle of the connecting rod 18. An adjusting roller 16 is installed on the surface of the fixed shaft 17. A positioning block 19 is installed inside the adjusting roller 16. The column 4 is equipped with locking blocks 6 on both sides. The surface of the locking blocks 6 is provided with an inlet 7, which facilitates the feeding of finished tea leaves. The bottom of the two locking blocks 6 is equipped with a connecting pipe 9, which facilitates the collection of finished tea leaves. The connection between the connecting pipe 9 and the locking blocks 6 is arc-shaped, which facilitates the sliding of tea leaves and prevents them from accumulating in the arc-shaped pipe. The bottom of the connecting pipe 9 is equipped with an feeding rod 13, which can feed the collected tea leaves. The bottom of the feeding rod 13 is arc-shaped, which facilitates the feeding of tea leaves to the contact point between the active roller 15 and the adjusting roller 16.

[0054] In this embodiment, the bottom of the first collection box 21 and the bottom of the second collection box 28 are both funnel-shaped. A first collection pipe 29 is installed at the bottom of the first collection box 21, and a second collection pipe 30 is installed at the bottom of the second collection box 28. An opening 32 is provided at the bottom of both the first collection pipe 29 and the second collection pipe 30. A support rod 33 is installed through the surface of the opening 32, and a blocking plug 31 is installed at the top of the support rod 33. The top of the blocking plug 31 is arc-shaped. The first collection pipe 29 can collect tea powder, and the second collection pipe 30 can collect flour. The opening 32 and the blocking plug 31 cooperate with each other to facilitate the tea powder or flour to fall from the first collection pipe 29 and the second collection pipe 30 or to stop the falling.

[0055] In this embodiment, baffles 24 are installed on both sides of the bottom of the first collection tube 29 and the second collection tube 30. A first storage cylinder 34 and a second storage cylinder 36 are respectively installed between the two baffles 24. The inclination angle of the side of the first storage cylinder 34 is smaller than that of the side of the second storage cylinder 36. Two first photosensitive films 35 are installed on the inner wall of the first storage cylinder 34. A second photosensitive film 37 is installed inside the second storage cylinder 36. The mass of material stored between the position of the first photosensitive film 35 and the bottom of the first storage cylinder 34 is 50g, and the mass of material stored between the position of the second photosensitive film 37 and the bottom of the second storage cylinder 36 is 950g. The quantities of tea powder and flour can be determined by the first storage cylinder 34, the second storage cylinder 36, the first photosensitive film 35, and the second photosensitive film 37, maintaining a good ratio between tea powder and flour, which is beneficial to the gelatinization characteristics of flour in subsequent tea flour processing.

[0056] In this embodiment, a seepage port 38 is installed at the bottom of the support rod 33. During the process of the second push rod motor 39 driving the support rod 33 to move up and down, flour or tea powder can pass through the seepage port 38. The tea powder or flour at both ends of the support rod 33 are kept at the same horizontal line. A guide block 40 is installed at the bottom of the inside of the first storage cylinder 34 and the bottom of the inside of the second storage cylinder 36. The bottom of the outer wall of the first storage cylinder 34 and the bottom of the outer wall of the second storage cylinder 36 are provided with the second push rod motor 39. The top of the second push rod motor 39 is connected to the bottom of the support rod 33.

[0057] In this embodiment, the guide block 40 is composed of two trapezoidal bottoms connected together. The tilt angle of the top of the guide block 40 is greater than the tilt angle of the bottom. A gate valve 41 is installed at the bottom of the guide block 40. The guide block 40 at the top can effectively allow the material to slide down. After the gate valve 41 is opened, the guide block 40 at the bottom can allow the material guide block 40 to slide down from the side and inside the gate valve 41.

[0058] In this embodiment, a mixing box 10 is installed at the bottom of the tea grinding box 1 and the flour grinding box 2. A rotating motor 11 is installed inside the mixing box 10. A stirring rod is installed at one end of the rotating motor 11. A discharge port 12 is installed on the surface of the mixing box 10 to uniformly mix a certain proportion of tea powder and flour to ensure the gelatinization characteristics of the flour in the subsequent dough formation.

[0059] This embodiment enables the collection of tea powder and flour through the first collection tube 29 and the second collection tube 30, respectively. The first photosensitive film 35 and the second photosensitive film 37 can determine the volume of tea powder and flour, facilitating subsequent determination of their proportions. This ensures that the tea content in the tea-flour mixture is 5%, maintaining the gelatinized characteristics of the tea-flour mixture after it clumps together. Tea powder inside the first collection box 21 falls into the first collection tube 29, and flour inside the second collection box 28 falls into the second collection tube 30, and then drips through the opening 32 into both collection tubes. Between the baffles 24, as tea powder and flour accumulate, they will respectively block the two first photosensitive films 35 and the second photosensitive film 37. When the first photosensitive film 35 or the second photosensitive film 37 is completely blocked, it indicates that the weight of the tea powder or flour has reached the specified weight. The second push rod motor 39 is then controlled to move downward. At this time, the second push rod motor 39 can drive the support rod 33 to move downward, thereby causing the blocking plug 31 to block the opening 32 and prevent the tea powder and flour from falling. At this time, the two gate valves 41 are opened, allowing the tea powder or flour to fall from the gap and collect inside the mixing box 10.

[0060] It should be noted that this invention relates to a fine sieving device and its working method for processing tea flour. In use, the required sieve mesh size for the tea powder is first adjusted by raising and lowering the first pusher motor 14. The adjustment method is as follows: when a larger diameter tea powder is needed (i.e., a smaller sieve mesh size), the pusher of the first pusher motor 14 is moved upwards. This increases the distance between the active roller 15 and the positioning block 19 of the adjusting roller 16. At this time, the tea powder ground by the active roller 15 and the adjusting roller 16 has a larger diameter. Simultaneously, as the pusher motor drives the adjusting roller 16 upwards, it also drives the filter plate 20 upwards. The filter plate 20 rotates upwards relative to the side of the support base 3. At this time, the gravitational force of the baffle 24 can compress the spring 23 to a certain extent, increasing the distance between the baffle 24 and the side of the slot 22, thus filtering tea powder with a smaller sieve mesh size. When a smaller diameter tea powder is needed... When the sieve mesh of the tea powder is large, the push rod of the first push rod motor 14 moves downward, which reduces the distance between the active roller 15 and the positioning block 19 of the adjusting roller 16. At this time, the diameter of the tea powder ground by the active roller 15 and the adjusting roller 16 is smaller. At the same time, as the push rod motor drives the adjusting roller 16 to move downward, it can drive the filter plate 20 to move downward. The filter plate 20 and the side of the support base 3 rotate upward. At this time, the component of gravity of the baffle 24 can amplify the spring 23 to a certain extent. The distance between the baffle 24 and the side of the slot 22 is reduced, which can filter tea powder with a larger sieve mesh. The finished tea is put into the locking block 6. The finished tea is put into the locking block 6. At this time, the tea will slide from the locking block 6 to the connecting pipe 9 and fall from the bottom of the feeding rod 13 into the space between the active roller 15 and the adjusting roller 16 for grinding. The ground tea powder will fall into the interior of the first collection box 21.During the grinding of tea leaves, wheat can be ground into flour simultaneously. A sieve 26 of the required mesh size is prepared in advance. Wheat is fed into the feed inlet 8 and ground by two grinding rollers 25. During the grinding process, the flour is sieved by the combined action of the vibrator 27 and the sieve 26, causing flour of the correct mesh size to fall into the second collection box 28. Tea powder in the first collection box 21 falls into the first collection pipe 29, and flour in the second collection box 28 falls into the second collection pipe 30, and then falls through the opening 32 between the two baffles 24. As the tea powder and flour accumulate, they respectively affect the two first collection boxes 28. The first photosensitive film 35 and the second photosensitive film 37 are blocked. When either the first photosensitive film 35 or the second photosensitive film 37 is completely blocked, it indicates that the weight of the tea powder or flour has reached the specified weight. The second push rod motor 39 is then controlled to move downwards. At this time, the second push rod motor 39 drives the support rod 33 to move downwards, thereby causing the blocking plug 31 to block the opening 32, preventing the tea powder or flour from falling. Then, the two gate valves 41 are opened, allowing the tea powder or flour to fall through the gap and collect inside the mixing tank 10. The rotating motor 11 is then turned on, causing it to drive the stirring rod to rotate, allowing the powder to flow out from the discharge port 12, completing the sieving and mixing of the tea powder and flour.
