Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a cooling device for tea production and processing. Background Art

[0002] Tea is a famous drink unique to my country and is sold both at home and abroad. Tea is mainly made by brewing tea leaves. During the production and processing of tea leaves, it needs to go through several processing steps. After the tea leaves are withered, they need to be cooled to ensure that the tea has good quality.

[0003] At present, a cooling device is needed to cool the tea leaves after withering. Workers will put the withered tea leaves into a screening cylinder, which will slowly pour out the tea leaves. A fan will then be used to cool the slowly poured tea leaves. This will not only cool the tea leaves, but will also screen the tea leaves and remove impurities from the tea leaves. However, when cooling the tea leaves in this way, the tea leaves blown out by the fan will cause the leaf buds and impurities to be graded according to weight. However, it is not easy to store the tea leaves after cooling in this way. When using a fan to cool the tea leaves, the tea leaves in the screening cylinder cannot be cooled quickly, which is time-consuming. Therefore, we propose a cooling device for tea production and processing to solve the above problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-3 A cooling device for tea production and processing includes a support platform 1 and a screening cylinder 2, a vertical plate 3 and two fixed plates 4 fixedly arranged on the top of the support platform 1, the tops of the two fixed plates 4 are fixedly connected to the same metal sealing protective cylinder 5, and the outer wall of the metal sealing protective cylinder 5 is provided with two rotation holes 6;

[0019] The screening cylinder 2, the metal sealing protective cylinder 5 and the rotating hole 6 are coaxially arranged. The metal sealing protective cylinder 5 is made of metal. The metal has strong thermal conductivity, which is more conducive to the cooling of the tea leaves in the screening cylinder 2. The metal sealing protective cylinder 5 is made of metal with good thermal conductivity, which is more convenient for cooling and dissipating heat from the tea leaves.

[0020] The outer wall of the screening cylinder 2 and the inner walls of the two rotating holes 6 are rotatably connected. The vertical distance between the bottom of the screening cylinder 2 and the supporting platform 1 is gradually shortened from high to low. The shape and position of the screening cylinder 2 and the metal sealing protective cylinder 5 are as follows: Figure 1 As shown, a plurality of vent holes 7 are opened on the outer wall of the screening cylinder 2, and a connecting pipe head 8 communicating with the screening cylinder 2 is fixedly connected to the outer wall of the metal sealing protection cylinder 5, and the outer wall of the screening cylinder 2 and the inner wall of the connecting pipe head 8 are rotatably connected;

[0021] A feed funnel 9 is fixedly connected to the outer wall of the connecting pipe head 8, a discharge limit frame 10 connected to the screening cylinder 2 is fixedly connected to the top of the vertical plate 3, a motor 11 is fixedly connected to the top of the metal sealing protective cylinder 5, a gear ring 12 is fixedly sleeved on the outer wall of the metal sealing protective cylinder 5, and a gear 13 meshing with the gear ring 12 is fixedly sleeved on the output shaft of the motor 11. The motor 11 is a common means in the prior art and will not be described in detail here.

[0022] An annular cavity 14 is formed inside the connecting pipe head 8. An air injection pipe 15 and a plurality of air outlet nozzles 16 are fixedly connected to the outer and inner walls of the connecting pipe head 8, both of which are connected to the annular cavity 14. The distance between two adjacent air vents 7 is the same, and the plurality of air outlet nozzles 16 are distributed in an annular array on the inner wall of the connecting pipe head 8.

[0023] The top of the metal sealing protective tube 5 is fixedly connected to the air inlet pipe 17. One end of the air injection pipe 15 and the air inlet pipe 17 are connected to the same fan. Figure 1 As shown in FIG. 1 , the fan can inject cooling air into the air injection pipe 15 and the air inlet pipe 17 for cooling. The fan for injecting cooling air is a common method in the prior art and will not be described in detail here.

[0024] The bottom of the metal sealing protective cylinder 5 is provided with an exhaust and impurity discharge integrated port 18, and the inner wall of the screening cylinder 2 is fixedly connected with a plurality of semicircular material blocking plates 19. The shape of the semicircular material blocking plates 19 is as follows: Figure 3 As shown, the top of the support platform 1 is slidably connected to a tea collection frame 20 and a debris collection frame 21, which are respectively located directly below the discharge limit frame 10 and the exhaust and debris discharge integrated port 18. The tea collection frame 20 and the debris collection frame 21 can respectively collect the cooled and screened tea leaves and collect the miscellaneous leaves and debris screened from the tea leaves.

[0025] The functional principle of the present invention can be explained through the following operation mode: when using the device to cool tea leaves, tea leaves to be cooled are poured into the feeding funnel 9, the tea leaves enter the connecting pipe head 8, and finally the tea leaves are allowed to stay on the semicircular material blocking plate 19 at the top of the screening cylinder 2;

[0026] By starting the fan connected to the air injection pipe 15 and the air inlet pipe 17, the fan injects air into the annular cavity 14 through the air injection pipe 15, and then allows the cooling air to pass through the annular cavity 14 and be ejected to the multiple air outlet nozzles 16. The cooling air ejected from the air outlet nozzles 16 is sprayed into the screening drum 2, and the cooling air will flow in the screening drum 2 and finally be discharged from the bottom of the discharge limit frame 10.

[0027] At the same time, the cooling air will enter the metal sealed protective cylinder 5 through the multiple vent holes 7 on the multiple screening cylinders 2. At the same time, the cooling air will also enter the metal sealed protective cylinder 5 from the air inlet pipe 17, and the cooling air will be discharged through the exhaust and impurity discharge port 18. When the cooling air passes through the tea leaves in the screening cylinder 2, the cooling air will cool the tea leaves.

[0028] The motor 11 is started, and the output shaft of the motor 11 engages the gear ring 12 through the gear 13 thereon, thereby driving the screening drum 2 to rotate. The screening drum 2 drives the tea leaves therein to rotate, thereby causing the tea leaves in the screening drum 2 to be turned over. The cooling air cools the turned tea leaves as it passes through them, and the tea leaves are turned over in the screening drum 2. The cooled tea leaves are discharged from the discharge limit frame 10 into the tea collection frame 20.

[0029] When the tea leaves are turned over in the screening cylinder 2, smaller impurities will enter the metal sealing protective cylinder 5 through the vent 7 and eventually fall into the debris collection frame 21 from the exhaust and impurity discharge port 18 for accumulation until all the tea leaves are cooled and processed. When the tea leaves in the screening cylinder 2 are processed, the motor 11 and the fan are turned off to complete the cooling process of the tea leaves.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
