Description

Technical Field

[0001] The present invention relates to the technical field of tea drying devices, in particular to a drying device for tea processing. Background Art

[0002] Tea processing, also known as "tea making," is the process of transforming fresh tea leaves through various steps into various semi-finished or finished teas. Depending on the processing steps, these processes can be divided into primary processing (primary processing), refining (fine processing), secondary processing, and further processing. Different processing techniques result in different types of tea, and the quality of each type of tea depends on the coordination of the processing steps. Only when high-quality fresh leaves are processed under excellent conditions can high-quality tea be produced.

[0003] Freshly picked tea leaves usually have a high water content, making them prone to mold and spoilage. Drying can significantly reduce the moisture content of tea leaves, generally controlling it to 5%-7%. Within this range, microorganisms are less likely to survive, oxidation reactions are slowed, and tea leaves can be preserved for a long time, with stable quality. The high temperature during tea drying can destroy enzyme activity, halt the oxidation process, and stabilize the quality characteristics of tea leaves at a specific stage. When drying tea leaves, they are usually placed on a screen, spread evenly, and placed in a drying oven for heating and drying. Finally, the dried tea leaves are removed. However, current drying equipment has a fixed internal heat source, and the drying speed of the outer and inner layers of tea leaves differs, which can easily lead to quality differences between the inner and outer layers.

DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] Reference Figure 1-13A drying device for tea processing comprises a heat-insulating shell 1, an equipment bin 3 is provided at the bottom end of the inner wall of the heat-insulating shell 1, and a multi-layer partition 5 is provided at the top end of the inner wall of the heat-insulating shell 1, and a drying bin 6 is provided between each layer of partition 5, an equipment bin door 9 is provided on the outside of the equipment bin 3, and a drying bin door 10 is provided on the outside of the drying bin 6, a heat source recovery mechanism 4, a hot air mechanism 2 and a hot air distribution mechanism 11 are installed in sequence inside the equipment bin 3, and the hot air mechanism 2 is installed between the heat source recovery mechanism 4 and the hot air distribution mechanism 11, the heat source recovery mechanism 4 and the hot air distribution mechanism 11 both pass through the partition 5 and extend to the inside of the drying bin 6, a telescopic carrier 8 is fixedly installed inside the drying bin 6, and a holding mechanism 7 is clamped on the top of the telescopic carrier 8, and a driving component for driving the telescopic carrier 8 to rotate is rotatably installed between the partitions 5.

[0034] The tea leaves are evenly heated by the hot air flow, and the tea leaves are evenly heated by the hot air flow.

[0035] As a further solution in the present invention, the hot air mechanism 2 includes a collector 23 connected to the heat source recovery mechanism 4, and a heater 21 connected to the heat source recovery mechanism 4. A circulating fan 22 is installed between the collector 23 and the heater 21, and a dehumidifier is installed inside the collector 23. In the present invention, the circulating fan 22 is used to construct a hot air circulation between the heat source recovery mechanism 4 and the hot air distribution mechanism 11, and the dehumidifier installed inside the collector 23 is used to control the humidity of the circulating hot air to avoid the appearance of water droplets during the hot air circulation process that affect the quality of tea. At the same time, a hot air circulation is constructed inside the device to avoid the entry of external dust and the overflow of fluff detached from the surface of the internal tea leaves, thereby protecting the working environment.

[0036] As a further solution in the present invention, the hot air distribution mechanism 11 includes a V-shaped diversion cover 111, and two air distribution pipes installed at the end of the diversion cover 111. The air distribution pipe runs through multiple drying bins 6, and a section of the air distribution pipe located inside the drying bin 6 is installed with an extension pipe 112 through a solenoid valve, and an arc-shaped dispersion cover 113 is installed at the end of the extension pipe 112. In the present invention, an arc-shaped dispersion cover 113 is installed on both sides of each holding mechanism 7. The hot air is ejected from the two sides of the bottom of the holding mechanism 7 through the setting of the dispersion cover 113, and then moves upward from the bottom of the holding mechanism 7 to pass through the internal surface of the tea leaves. The hot air dries the tea leaves through the gaps between them, ensuring that the tea leaves are heated evenly during the drying operation.

[0037] As a further solution in the present invention, the heat source recovery mechanism 4 includes two recovery pipes 42 that pass through multiple drying bins 6, and a horizontal pipe is installed between the two recovery pipes 42 in a section inside the drying bin 6. A recovery cover 43 is installed at the bottom of the horizontal pipe and is sleeved on the upper end of the holding mechanism 7. A filter 41 is installed between the bottom of the recovery pipe 42 and the hot air mechanism 2. In the present invention, the recovery cover 43 is used to form a suction negative pressure environment at the upper end of the holding mechanism 7, which accelerates the speed of hot air passing through the gaps between the tea leaves, and can absorb impurities such as dust and fluff blown up from the surface of the tea leaves, and performs impurity removal operations while recovering heat inside the device, thereby improving the quality of the tea leaves.

[0038] As a further solution in the present invention, multiple groups of filter components are plugged into the interior of the filter 41, and each group of filter components consists of two fixed filter plates 45 and a movable filter plate 46 that slide against each other. The surfaces of the fixed filter plates 45 and the movable filter plates 46 are provided with staggered arc-shaped filter holes, and a pull rod is installed between the ends of multiple movable filter plates 46, and an electric push rod 44 is installed at the end of the pull rod. In the present invention, the surfaces of the fixed filter plates 45 and the movable filter plates 46 are provided with staggered arc-shaped filter holes. When the movable filter plate 46 moves driven by the electric push rod 44, the pore size between the two staggered arc-shaped filter holes changes, and the pores on the surface of the filter components of the previous group increase and the pores on the surface of the filter components of the latter group decrease, and the tea fluff intercepted by the filter holes is rubbed and collected to prevent the fluff from clogging the filter holes.

[0039] As a further solution in the present invention, the telescopic carrier 8 includes two push rod motors 81 connected to the inner wall of the insulation shell 1, and an annular bracket 82 installed between the two push rod motors 81. The annular bracket 82 is rotatably installed inside the annular bracket 83, and the bottom of the annular carrier 83 is provided with a gear ring that is transmission-connected to the drive assembly. In the present invention, the holding mechanism 7 is clamped in the annular carrier 83, and the holding mechanism 7 is driven by the push rod motor 81 to move in and out of the drying bin 6. The staff can place and spread the tea leaves on the outside of the device, and during the drying operation, drive the holding mechanism 7 and the tea leaves inside it to rotate, further improving the heating uniformity and stability during the tea drying operation.

[0040] As a further solution in the present invention, the driving assembly includes a transmission shaft passing through multiple drying bins 6, and multiple driving gears 84 installed on the outside of the transmission shaft, the driving gear 84 is meshed with the gear ring, and the driving assembly also includes a driving motor 85 installed inside the equipment bin 3, and the output shaft of the driving motor 85 is transmission-connected to the transmission shaft. In the present invention, after the telescopic carrier 8 is retracted into the drying bin 6, the gear ring at the bottom of the annular carrier 83 is meshed with the driving gear 84, thereby driving the containing mechanism 7 inside the annular carrier 83 to rotate.

[0041] As a further solution in the present invention, the holding mechanism 7 includes a holding tray 71, and a plurality of air holes 72 are provided at the bottom of the holding tray 71, a plurality of support rods 73 are provided at the bottom of the holding tray 71, and a collecting tray 74 is installed between the support rods 73. In the present invention, the supporting rods 73 are used to prop up the holding tray 71 to prevent the tea leaves from contacting the ground through the air holes 72 when the holding tray 71 is placed. At the same time, when the tea leaves are spread out in the holding tray 71, the setting of the collecting tray 74 can effectively collect the debris existing in the tea spreading process to avoid contamination of the drying bin 6. When the tea leaves are drying, hot air flows in from the gap between the holding tray 71 and the collecting tray 74 to guide and gather the hot air, thereby improving the heat utilization rate.

[0042] As a further solution in the present invention, the collecting tray 74 is slidably connected to the support rod 73, and a plurality of springs 75 are installed between the collecting tray 74 and the holding tray 71. A magnetic block 77 is installed in the center of the bottom of the collecting tray 74, and an electromagnet 12 adapted to the magnetic block 77 is installed on the top of the partition 5. In the present invention, when the electromagnet 12 is turned on, the electromagnet 12 attracts the magnetic block 77 and the collecting tray 74 to move downward. When the electromagnet 12 is turned off, the collecting tray 74 moves upward under the action of the spring 75, thereby squeezing the hot air between the holding tray 71 and the collecting tray 74. After being compressed, the hot air is ejected from the air vent 72, thereby driving the surrounding tea leaves to vibrate, causing movement between the tea leaves, changing the gap between the tea leaves, and using vibration to increase the contact area between the tea surface and the hot air, thereby improving the tea drying efficiency. At the same time, it effectively screens out debris and impurities in the tea leaves and improves the quality of the tea leaves.

[0043] As a further solution in the present invention, a plurality of elastic rods 76 distributed in a rectangular array are provided on the top of the collection tray 74, and the elastic rods 76 correspond to the air holes 72. In the present invention, when the collection tray 74 rotates, the elastic rods 76 form an air guide structure between the collection tray 74 and the holding tray 71. When the holding mechanism 7 rotates, the position of the elastic rods 76 and the hot air risk changes, which produces different guiding effects on the hot air, further improving the hot air flow effect. Secondly, the elastic rods 76 are used to capture the debris sieved by the air holes 72, and the hot air on both sides is used to gather the debris to the middle of the collection tray 74 to prevent the debris from falling into the drying bin 6. At the same time, when the collection tray 74 moves up and down, the elastic rods 76 pass through the air holes 72 and hit the tea leaves on the bottom layer, further enhancing the movement effect of the tea leaves, and improving the heat exchange effect with the hot air through the movement of the tea leaves.

[0044] The tea leaves are evenly heated by the hot air flow, and the tea leaves are evenly heated by the hot air flow.

[0045] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
