Description

Technical Field

[0001] The present invention belongs to the technical field of mulberry tea beverage detection, and particularly relates to a mulberry tea beverage detection device. Background Art

[0002] Mulberry tea is made from precious mulberry leaves tea and more than a dozen herbal foods that are both food and medicine. It is prepared through scientific compatibility, strict raw material selection, and excellent processing. The product is rich in a large number of nutrients and trace elements beneficial to the human body, and is a natural food herbal series beverage that is convenient to carry and suitable for brewing all year round. The water leaching concentration of its raw material components is sufficient and complete. During the frying process of mulberry leaves tea, the water content in the mulberry leaves needs to be strictly controlled.

[0003] When the water content in the mulberry leaves tea exceeds the standard, aromatic substances such as dimethyl sulfide and phenylethyl alcohol that form the aroma of the new tea are sharply reduced, while volatile components that are unfavorable to the aroma increase significantly, resulting in the deterioration of the quality of the mulberry leaves tea. Therefore, to ensure the qualified taste and quality of the mulberry tea beverage, it is necessary to strictly control the water content in the mulberry leaves tea.

[0004] Existing mulberry tea beverage detection devices generally can use visual detection equipment to collect the color of the stir-fried tea leaves, and then judge the water content in the tea leaves according to the color of the tea leaves. However, during the process of stir-frying tea leaves, a large amount of water vapor evaporates into the air, which not only affects the image acquisition effect of the visual detection equipment, but also the water vapor in the air adhering to the surface of the tea leaves can affect the judgment of the water content in the tea leaves; further, during the process of stir-frying tea leaves, the tea leaves are constantly mixed, which is prone to uneven distribution, and at the same time, a large amount of broken materials adhering to the tea leaves will also affect the judgment of the water content in the tea leaves.

[0018] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0019] As Figures 1-7 shown, a mulberry tea beverage detection device provided by an embodiment of the present invention includes a tank body 1. A detection cylinder 2 is provided at the top of the tank body 1. An air inlet pipe 13 and an air outlet pipe 15 are connected between the detection cylinder 2 and the tank body 1. An air pump 14 is provided between the air inlet pipe 13 and the tank body 1. A feeding trough 10 is connected to the top of the tank body 1. A second motor 11 is connected to the bottom of the tank body 1. The output shaft of the second motor 11 is connected to a rotating pipe 12. A bottom plate 20 is provided on the rotating pipe 12. The rotating pipe 12 is connected to a heating rack 16. A plurality of conical cylinders 17 are fixedly connected to the heating rack 16 at equal intervals. A bottom plate 20 is fixedly connected to a position near the bottom of the conical cylinder 17. A cavity 18 is formed in the conical cylinder 17. A plurality of ventilation holes 9 communicating with the cavity 18 are formed in the side wall of the conical cylinder 17. A rotating assembly 4 is provided in the middle of the conical cylinder 17. A connecting mechanism 6 is connected between the rotating assembly 4 and the conical cylinder 17. The connecting mechanism 6 can make the conical cylinder 17 communicate with the heating rack 16 or the rotating assembly 4 communicate with the inside of the conical cylinder 17. The rotating assembly 4 is connected to a heating and stirring mechanism 5. The heating and stirring mechanism 5 is connected to a vibrating mechanism 7 capable of vibrating vertically. The air outlet pipe 15 is connected to a visual detection assembly 3 capable of lifting vertically. The visual detection assembly 3 can detect the water content through the color of the mulberry tea leaves in the conical cylinder 17. Solenoid valves are provided on both the rotating pipe 12 and the air outlet pipe 15. A filtering mechanism 8 capable of absorbing moisture in the air is provided in the detection cylinder 2. The filtering mechanism 8 can judge the water content of the mulberry tea leaves according to the weight of the absorbed moisture. A control system, which can adjust the rotating assembly 4, the heating mechanism 5, the connecting mechanism 6, and the air pump 14 according to the difference between the water contents of the mulberry tea leaves measured by the visual detection assembly 3 and the filtering mechanism 8 respectively.

[0020] In the embodiment of the present invention, the second motor 11 drives the rotating pipe 12 to rotate. The rotating pipe 12 drives all the conical cylinders 17 to rotate through the heating rack 16. The conical cylinders 17 are sequentially moved to the position directly below the feeding trough 10, and mulberry tea leaves are poured into each conical cylinder 17 in sequence, and then the feeding trough 10 is closed. Normal drying stage: Start the electric heating mechanism 5 in each conical cylinder 17. Each electric heating mechanism 5 heats and stirs the mulberry tea leaves in the corresponding conical cylinder 17. The moisture in the mulberry tea leaves evaporates into the air in the tank body 1. At this time, start the connecting mechanism 6 in each conical cylinder 17 to conduct the corresponding electric heating rack 16 with the conical cylinder 17; Start the air pump 14. The air pump 14 pumps the humid hot air in the tank body 1 into the detection cylinder 2. The filtering mechanism 8 in the detection cylinder 2 absorbs the moisture in the air. At this time, the solenoid valve on the rotating pipe 12 is conducted, and the solenoid valve on the air outlet pipe 15 is closed. The dried air passes through the electric heating rack 16 in the rotating pipe 12 and is led out to each conical cylinder 17. The hot air sprays into the conical cylinder 17 from each ventilation hole 9 through the cavity 18. Since the inside of the conical cylinder 17 is conical, the hot air can obliquely upward air-dry the mulberry tea leaves, and the internal space at the upper part of the conical cylinder 17 is larger, thus further increasing the dispersion effect of the mulberry tea leaves, increasing the contact area between the mulberry tea leaves and the hot air, and improving the drying effect of the mulberry tea leaves; The weight of the moisture lost by the mulberry tea leaves can be determined by the weight of the moisture absorbed by the filtering mechanism 8. The weight of the moisture absorbed by the filtering mechanism 8 divided by the original weight of the mulberry tea leaves is equal to the moisture content of the mulberry tea leaves. In order to more accurately measure the moisture content of the mulberry tea leaves, in this embodiment, the moisture content of the mulberry tea leaves is detected by the visual detection component 3: Stage of detecting the moisture content of mulberry tea leaves by the visual detection component 3: Start each conical cylinder 17 to stop rotating. At this time, a conical cylinder 17 is directly below the visual detection component 3. The visual detection component 3 moves downward to close the conical cylinder 17 directly below. At this time, the solenoid valve on the rotating pipe 12 is closed, and the solenoid valve on the air outlet pipe 15 is conducted. The rotating component 4 in the conical cylinder 17 directly below the visual detection component 3 is separately communicated with the conical cylinder 17. At this time, the dried air in the detection cylinder 2 is led out from the air outlet pipe 15. The dried air flows from top to bottom into the conical cylinder 17 directly below the visual detection component 3. At this time, the mulberry tea leaves in the conical cylinder 17 directly below the visual detection component 3 are concentrated towards the bottom of the conical cylinder 17 by the wind force, and the dried air flows through each ventilation hole 9 and the rotating component 4 into the electric heating rack 16. Then the hot air dries the mulberry tea leaves in the remaining conical cylinders 17; In this way, the dried air in the detection cylinder 2 can be concentrated to take away the moisture in the conical cylinder 17 directly below the visual detection component 3, avoiding excessive water vapor in the conical cylinder 17 directly below the visual detection component 3 from affecting the detection result, and at the same time concentrating the mulberry tea leaves in the conical cylinder 17 directly below the visual detection component 3 together, which is convenient for detecting the mulberry tea leaves in the conical cylinder 17 directly below the visual detection component 3; Start the air pump 14 to stop the wind force transportation, and at the same time start the electric heating mechanism 5 in the conical cylinder 17 directly below the visual detection component 3 to stop rotating. The visual detection component 3 collects and analyzes the color data of the mulberry tea leaves in the conical cylinder 17 directly below, so as to judge the moisture content of the mulberry tea leaves in the conical cylinder 17 directly below the visual detection component 3; The control system can adjust the rotating assembly 4, the electric heating mechanism 5, the connecting mechanism 6 and the air pump 14 according to the difference in the water content of mulberry tea leaves measured by the visual detection component 3 and the filtering mechanism 8 respectively, so as to improve the measurement accuracy of the water content of mulberry tea leaves.

[0021] As Figure 4 shown, as a preferred embodiment of the present invention, the visual detection component 3 includes a first electric telescopic sleeve 31, a sealing disc 32 and a visual detector 33; The first electric telescopic sleeve 31 is fixedly connected to the upper end surface of the tank body 1, and the first electric telescopic sleeve 31 is connected to the air outlet pipe 15. The telescopic end of the first electric telescopic sleeve 31 is fixedly connected to a sealing disc 32, and the lower end surface of the sealing disc 32 is fixedly connected to a visual detector 33.

[0022] In the embodiment of the present invention, when the first electric telescopic sleeve 31 is started to extend, the first electric telescopic sleeve 31 can drive the sealing disc 32 to move downward, and the sealing disc 32 can contact the lower conical cylinder 17. Then, the visual detector 33 can take pictures of the color of the mulberry tea leaves in the conical cylinder 17, so as to judge the water content of the mulberry tea leaves according to the color change of the mulberry tea leaves.

[0023] As Figure 3 shown, as a preferred embodiment of the present invention, the rotating assembly 4 includes a first motor 41 and a rotating shaft 42. The first motor 41 is fixedly connected to the fixed frame 19 inside the conical cylinder 17, the telescopic end of the first motor 41 is fixedly connected to a rotating shaft 42, and the lower end of the rotating shaft 42 is connected to the electric heating frame 16.

[0024] In the embodiment of the present invention, when the first motor 41 is started, the first motor 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the electric heating mechanism 5 to rotate. The electric heating mechanism 5 can stir and heat the mulberry tea leaves in the conical cylinder 17.

[0025] As Figure 5 shown, as a preferred embodiment of the present invention, the electric heating mechanism 5 includes a rotating rod 51, a scraping bar 52, a connecting rod 53, an electric heating and dividing rod 54 and a second electric telescopic sleeve 55; The rotating rod 51 is fixedly connected to the rotating shaft 42. Scraping bars 52 are rotatably connected to both ends of the rotating rod 51. Connecting rods 53 are rotatably connected to the scraping bars 52. The fixed frame 19 is fixedly connected to a second electric telescopic sleeve 55. The telescopic end of the second electric telescopic sleeve 55 is rotatably connected to one end of the connecting rod 53. A number of electric heating and dividing rods 54 are distributed along the length direction of the electric heating and dividing rod 54.

[0026] In the embodiment of the present invention, during the normal drying stage, the second electric telescopic sleeve 55 is started to contract. At this time, the second electric telescopic sleeve 55 pulls the scraping bar 52 through the connecting rod 53. At this time, the scraping bar 52 drives each electric heating material distributing rod 54 to be in the middle of the conical cylinder 17. Since the wind force in the conical cylinder 17 is sprayed obliquely upward from different heights through each ventilation hole 9 at this time, the rotating shaft 42 drives each electric heating material distributing rod 54 to further disperse and mix the mulberry tea leaves, so that the mulberry tea leaves at different depths and different heights can be effectively dried; During the moisture content detection stage of the mulberry tea leaves by the visual detection component 3, in the conical cylinder 17 below the visual detection component 3: the second electric telescopic sleeve 55 is started to extend, and the second electric telescopic sleeve 55 pushes the scraping bar 52 to fit with the inner wall of the conical cylinder 17 through the connecting rod 53. At this time, each connecting rod 53 is simultaneously in contact with the inner wall of the conical cylinder 17; on the one hand, the scraping bar 52 can scrape off the mulberry tea leaves in the conical cylinder 17 below the visual detection component 3, so that the mulberry tea leaves can be concentrated towards the bottom of the conical cylinder 17. On the other hand, the connecting rod 53 can heat the conical cylinder 17, so that the moisture remaining on the inner wall of the conical cylinder 17 and the moisture in the cavity 18 are fully evaporated, increasing the dryness in the conical cylinder 17 and avoiding the influence of water vapor on the shooting effect of the visual detector 33 during detection, thereby affecting the detection result of the moisture content of the mulberry tea leaves.

[0027] As Figure 3 shown, as a preferred embodiment of the present invention, the connection mechanism 6 includes a connecting pipe 61, a stop valve 62, a guide hole 63 and a third electric telescopic sleeve 64; A connecting pipe 61 is fixedly arranged at a position near the bottom of the rotating shaft 42. A stop valve 62 is arranged on the connecting pipe 61. The connecting pipe 61 is communicated with the cavity 18. A guide hole 63 and a third electric telescopic sleeve 64 are arranged on the rotating shaft 42. The telescopic end of the third electric telescopic sleeve 64 can close the guide hole 63, and a net is arranged on the guide hole 63.

[0028] In the embodiment of the present invention, during the normal drying stage: the stop valve 62 is opened, and the third electric telescopic sleeve 64 extends to close the guide hole 63. At this time, air enters the electric heating frame 16 through the rotating pipe 12, and then is transported by the electric heating frame 16 to the cavity 18 inside each conical cylinder 17. The electric heating frame 16 heats the air, and the hot air disperses and dries the mulberry tea leaves obliquely upward through each ventilation hole 9 in the conical cylinder 17; The visual detection component 3 conducts the moisture content detection stage of mulberry tea leaves: The cut-off valve 62 in the conical cylinder 17 below the visual detection component 3 is closed, and the third electric telescopic sleeve 64 in the conical cylinder 17 below the visual detection component 3 contracts to conduct the guide hole 63. At this time, the dried air flows through the air outlet pipe 15 into the conical cylinder 17 below the visual detection component 3. The air enters the electric heating rack 16 through the respective ventilation holes 9 and the guide hole 63 in the conical cylinder 17 below the visual detection component 3, and then is dispersed to the other conical cylinders 17 by the electric heating rack 16. During this process, since the conical cylinder 17 is conical, when the air flows downward in the conical cylinder 17 below the visual detection component 3, the wind pressure increases, causing the mulberry tea leaves in the conical cylinder 17 below the visual detection component 3 to concentrate towards the bottom of the conical cylinder 17.

[0029] As Figure 6 shown, as a preferred embodiment of the present invention, the vibration mechanism 7 includes a vertical rod 71, a push plate 72, a spring 73, and a transmission rod 74; The electric heating rack 16 is vertically slidably connected with a vertical rod 71. The upper end of the vertical rod 71 is fixedly connected with a push plate 72. A spring 73 is connected between the push plate 72 and the electric heating rack 16. The bottom of the vertical rod 71 is fixedly connected with a transmission rod 74. A guiding gear 75 is fixedly connected to the bottom plate 20. When the height of the vertical rod 71 decreases, the transmission rod 74 elastically abuts against the guiding gear 75.

[0030] In the embodiment of the present invention, during the moisture content detection stage of the mulberry tea leaves by the visual detection component 3, in the conical cylinder 17 below the visual detection component 3: At this time, the wind blows from top to bottom, and at the same time, the mulberry tea leaves concentrate towards the bottom of the conical cylinder 17. The push plate 72 in the conical cylinder 17 is forced to move downward. The push plate 72 squeezes the spring 73, and at the same time, the push plate 72 drives the transmission rod 74 to engage with the guiding gear 75. When the rotating rod 51 drives the push plate 72 to move in a circular motion around the rotating shaft 42, at this time, under the guiding of the guiding gear 75 and the elastic force of the spring 73, the vertical rod 71 drives the push plate 72 to continuously vibrate vertically. The push plate 72 precipitates the debris in the mulberry tea leaves downward, preventing the debris in the mulberry tea leaves from adhering to the surface of the mulberry tea leaves, thereby affecting the detection of the visual detector 33, and at the same time preventing the mulberry tea leaves from blocking at the guide hole 63, affecting the flow of the air current in the conical cylinder 17.

[0031] As Figure 7 shown, as a preferred embodiment of the present invention, the filtering mechanism 8 includes a filter plate 81, a weighing device 82, and a fixing rod 83; A plurality of filter plates 81 are vertically slidably connected in the detection cylinder 2. All the filter plates 81 are commonly connected with a weighing device 82. The bottom of the detection cylinder 2 is fixedly connected with a fixing rod 83. The lower end of the weighing device 82 abuts against the fixing rod 83. A temperature controller is provided in the detection cylinder 2.

[0032] In the embodiment of the present invention, each filter plate 81 can absorb the moisture entering the detection cylinder 2, and then the dried air flows out into the tank body 1. The temperature in the detection cylinder 2 is regulated to prevent the moisture in the detection cylinder 2 from evaporating back into the air. The weight change of all the filter plates 81 is detected by the weighing device 82, so as to determine the weight of the moisture absorbed by the mulberry tea leaves in the weighing device 82.

[0033] In the embodiment of the present invention, the regulation system includes a data processor and a PLC controller. The data processor is used to compare the difference between the moisture contents measured by the visual detection component 3 and the filtering mechanism 8 with the preset moisture content difference threshold in the data processor, and form a judgment message; the PLC controller is used to receive the judgment message and regulate the rotating component 4, the electric heating mechanism 5, the connecting mechanism 6 and the air pump 14.

[0034] In the embodiment of the present invention, the average value between the moisture contents measured by the visual detection component 3 and the filtering mechanism 8 is used as the final measured value of the moisture content of the mulberry tea leaves. When the difference between the moisture contents measured by the visual detection component 3 and the filtering mechanism 8 exceeds the preset moisture content difference threshold in the data processor, it indicates that the error of the detection result of the moisture content of the mulberry tea leaves is relatively large at this time. When the moisture content of the air in the tank body 1 is relatively large, it will affect the detection result of the moisture content of the mulberry tea leaves measured by the filtering mechanism 8 at this time. At the same time, when the visual detection component 3 is detecting, if there is more moisture in the air in the conical cylinder 17 below the visual detection component 3, it will affect the detection result of the visual detector 33 at this time; Therefore, in the normal drying stage, the heating effect of the electric heating mechanism 5 and the electric heating frame 16 is improved, and at the same time, the pumping effect of the air pump 14 on the air is improved, so as to improve the absorption effect of the filtering mechanism 8 on the moisture in the air and increase the accuracy of the detection result of the filtering mechanism 8; in the stage of detecting the moisture content of the mulberry tea leaves by the visual detection component 3: increasing the rotation speed of the rotating component 4 can improve the stirring and heating effect of the electric heating mechanism 5 on the mulberry tea leaves in the conical cylinder 17 below the visual detection component 3, and at the same time improve the concentration effect of the mulberry tea leaves in the conical cylinder 17 below the visual detection component 3. The electric heating mechanism 5 drives the vibration mechanism 7 to improve the precipitation effect of the debris on the mulberry tea leaves, increase the detection accuracy of the moisture content of the mulberry tea leaves in the visual detection component 3, and finally improve the detection accuracy of the moisture content of the mulberry tea leaves.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
