[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please see Figure 1-4 The present invention provides the following technical solution: a withering device for black tea processing, comprising a box 1, a servo motor 2 mounted on one side surface of the box 1, a placement box 5 disposed inside the box 1, a hinged door panel 7 disposed on the side of the box 1 perpendicular to the servo motor 2, a temperature display 6 mounted on the surface of the hinged door panel 7, a storage component 3 disposed at the bottom of the placement box 5, and a withering adjustment component 4 disposed at the top of the box 1.
[0025] Specifically, the storage component 3 includes a sealing strip 31, a door 32, an inclined plate 33, an impurity collection plate 34, a perforated plate 35, a storage box 36, and a shaping component 37. The storage box 36 is located at the bottom of the placement box 5, and the shaping component 37 is installed on the top of the storage box 36. The perforated plate 35 is located inside the storage box 36, and the impurity collection plate 34 is located at the bottom of the perforated plate 35. Inclined plates 33 are fixed to both sides of the top surface of the impurity collection plate 34. A door 32 is located on one side of the storage box 36, and a sealing strip 31 is located on the side of the door 32 closest to the storage box 36.
[0026] By adopting the above technical solution, when using the storage component 3, after the black tea has finished withering in the placement box 5, the black tea is placed in the storage box 36. The black tea is supported by the perforated plate 35. The storage capacity of the black tea in the storage box 36 can be increased by the multiple perforated plates 35. At the same time, the black tea in the box is protected from moisture by the cooperation of the box door 32 and the sealing strip 31, preventing the black tea from being damaged by moisture during storage. This improves the storage function of the device and enhances its practicality.
[0027] Specifically, the shaping component 37 includes an air outlet pipe 371, a mounting bracket 372, a jet nozzle 373, a branch pipe 374, a filter screen 375, an air guide pipe 376, and an air pump 377. The air pump 377 is located on the top of the storage box 36, and the mounting bracket 372 is located at the bottom of the air pump 377. The branch pipe 374 is located inside the mounting bracket 372. The jet nozzle 373 is located on the bottom surface of the branch pipe 374. The air outlet pipe 371 is connected between the branch pipe 374 and the air pump 377. The air guide pipe 376 is connected to the input end of the air pump 377, and the filter screen 375 is connected to the end of the air guide pipe 376 away from the air pump 377.
[0028] By adopting the above technical solution, when using the shaping component 37, after the black tea has undergone high-temperature withering in the placement box 5, it is placed on the surface of the perforated plate 35. The air pump 377 is started, and external air is introduced into the box through the action of the air pump 377 and the air guide pipe 376. At the same time, the air passes through the filter screen 375 to remove impurities, and the gas is introduced into the branch pipe 374 through the air outlet pipe 371 and finally sprayed out by the jet nozzle 373. The gas cools down the black tea, so that the black tea can be shaped more quickly after withering, which is convenient for subsequent processing. Meanwhile, the impurities in the black tea will fall onto the surface of the impurity collection plate 34 along with the perforated plate 35, which can separate the impurities in the black tea, thereby improving the functionality of the device.
[0029] Specifically, the surface of the door 32 is provided with vent holes, and the two ends of the perforated plate 35 are provided with sliding grooves at the contact points with the inner wall of the storage box 36.
[0030] By adopting the above technical solution, the gas inside the storage box 36 can be easily discharged through the vent, and the perforated plate 35 can be easily pulled out by the operator through the sliding groove, thereby improving the transfer efficiency of black tea.
[0031] In this embodiment, when using the storage component 3, after the black tea has withered in the placement box 5, it is placed into the storage box 36. The perforated plate 35 supports the black tea, and the multiple perforated plates 35 increase the storage capacity of the storage box 36. Simultaneously, the cooperation of the box door 32 and the sealing strip 31 prevents the black tea from getting damp and damaged during storage, thus improving the storage function of the device and enhancing its practicality. When using the shaping component 37, after the black tea has undergone high-temperature withering in the placement box 5, it is placed on the surface of the perforated plate 35. The air pump 377 is then activated, and air is pumped through the air pump 377 and the air guide pipe 37... Under the action of 6, external air is introduced into the box. At the same time, the air passes through the filter screen 375 to filter out impurities. The air is introduced into the branch pipe 374 through the air outlet pipe 371 and finally sprayed out by the jet head 373. The air cools the black tea, so that the black tea can be shaped more quickly after withering, which is convenient for subsequent processing. Meanwhile, the impurities in the black tea will fall onto the surface of the impurity collection plate 34 through the perforated plate 35, which can separate the impurities in the black tea, thereby improving the functionality of the device. The air outlet facilitates the discharge of gas inside the storage box 36, and the slide groove makes it easy for the operator to pull the perforated plate 35, improving the transfer efficiency of black tea.
[0032] Example 2
[0033] The difference between this embodiment and embodiment 1 is that, specifically, the wilting adjustment component 4 includes a fan 41, a fixing plate 42, a heating box 43, a heating wire 44, a filter plate 45, an air outlet 46, a threaded plate 47, and a screw 48. The fan 41 is installed on the top surface of the housing 1, the bottom of the fan 41 is connected to the heating box 43, the fixing plates 42 are provided on both sides of the heating box 43, the screw 48 is provided inside the fixing plate 42, the threaded plate 47 is threadedly connected to the surface of the screw 48, the filter plate 45 is provided inside the heating box 43, the heating wire 44 is provided at the bottom of the filter plate 45, and the air outlet 46 is fixedly connected to the bottom surface of the heating box 43.
[0034] By adopting the above technical solution, when using the withering adjustment component 4, the black tea that needs to be withered is first placed in the placement box 5, and then the fan 41 is started to draw outside air into the heating box 43. The air in the heating box 43 is first filtered by the filter plate 45 to prevent external pollutants from entering the device and contaminating the black tea. Then the heating wire 44 heats the air in the heating box 43, and finally it is discharged through the air outlet 46 to the surface of the black tea. When withering black tea with different humidity levels, the position of the heating box 43 can be adjusted to wither black tea with different humidity levels to avoid over-withering. During adjustment, the screw 48 is rotated by turning the handwheel, which in turn drives the threaded plate 47 and the heating box 43 to move, thereby adjusting the distance between the air outlet 46 and the black tea to avoid over-withering and thus improve the withering quality of the device.
[0035] Specifically, a flexible hose connects the fan 41 and the heating box 43. A guide groove is provided on the surface of the fixing plate 42 on the side of the heating box 43 away from the screw 48, and a guide block is provided in the guide groove.
[0036] By adopting the above technical solution, the air output by the fan 41 can be introduced into the heating box 43 through the hose, without affecting the position adjustment of the heating box 43. The synchronous movement of the guide block in the guide groove can guide the heating box 43, thereby improving the stability of the movement of the heating box 43.
[0037] In this embodiment, when using the withering adjustment component 4, first place the black tea to be withered into the placement box 5, then start the fan 41 to draw outside air into the heating box 43. The air in the heating box 43 is first filtered by the filter plate 45 to prevent external contaminants from entering the device and contaminating the black tea. Then, the heating wire 44 heats the air in the heating box 43, and finally, the air is discharged through the air outlet 46 to the surface of the black tea. When withering black tea with different humidity levels, the position of the heating box 43 can be adjusted to wither the tea. Black tea with the same humidity level is withered to avoid over-withering. During adjustment, the screw 48 is rotated by turning the handwheel, which in turn drives the threaded plate 47 and the heating box 43 to move. This allows the distance between the air outlet 46 and the black tea to be adjusted, avoiding over-withering and improving the withering quality of the device. Air output from the fan 41 can be introduced into the heating box 43 through a hose without affecting the position adjustment of the heating box 43. The synchronous movement of the guide block in the guide groove guides the heating box 43, improving the stability of the movement of the heating box 43.
[0038] The structure and operating principle of the housing 1, servo motor 2, placement box 5, temperature display 6 and hinge door panel 7 in this utility model have been disclosed in a withering device for black tea processing disclosed in Chinese patent application number 202421201791.X.
[0039] The working principle and usage of this utility model: This utility model adjusts a withering device for black tea processing. When using the storage component 3, after the black tea has withered in the placement box 5, it is placed into the storage box 36. The perforated plate 35 supports the black tea, and the multiple perforated plates 35 increase the storage capacity of the storage box 36. Simultaneously, the cooperation of the box door 32 and the sealing strip 31 prevents the black tea from getting damp and damaged during storage, thus improving the storage function of the device and enhancing its practicality. When using the shaping component 37, after the black tea has undergone high-temperature withering in the placement box 5, it is placed into the storage box 36. When the air pump 377 is activated on the surface of the perforated plate 35, external air is introduced into the chamber through the action of the air pump 377 and the air guide pipe 376. Simultaneously, the air passes through the filter screen 375 to remove impurities, and is then introduced through the air outlet pipe 371 into the branch pipe 374, finally being ejected from the jet nozzle 373. This air cools the black tea, allowing it to set more quickly after withering, facilitating subsequent processing. Impurities in the black tea fall onto the impurity collection plate 34 along with the perforated plate 35, separating them and improving the functionality of the device. The air outlet facilitates the discharge of gas from the storage tank 36. The chute facilitates the operator's pulling of the perforated plate 35, improving the transfer efficiency of black tea. This utility model relates to an adjustment of a withering device for black tea processing. When using the withering adjustment component 4, first, the black tea to be withered is placed in the placement box 5. Then, the fan 41 is started, drawing external air into the heating box 43. The air in the heating box 43 is first filtered by the filter plate 45 to prevent external pollutants from entering the device and contaminating the black tea. Then, the heating wire 44 heats the air in the heating box 43. Finally, the air is discharged through the air outlet 46 to the surface of the black tea. This allows for the adjustment of black tea with different humidity levels. During withering, the position of the heating box 43 can be adjusted to wither black tea with different humidity levels, avoiding over-withering. During adjustment, the screw 48 is rotated by turning the handwheel, which in turn drives the threaded plate 47 and the heating box 43 to move, thereby adjusting the distance between the air outlet 46 and the black tea, avoiding over-withering and improving the withering quality of the device. Air output from the fan 41 can be introduced into the heating box 43 through a hose without affecting the position adjustment of the heating box 43. The synchronous movement of the guide block in the guide groove can guide the heating box 43, improving the stability of the movement of the heating box 43.
