Description

Technical Field

[0001] This utility model belongs to the field of black tea production and processing technology, and specifically relates to a cooling machine for black tea production. Background Technology

[0002] Black tea is a fully fermented tea, one of the six major tea categories in China. It is made from the buds and leaves of the tea plant, refined through typical processes such as withering, rolling, fermentation, and drying, with fermentation being the key step in its processing. It gets its name from the predominantly red color of its dry leaves and brewed tea. Cooling devices are required during the production and processing of black tea.

[0003] Chinese patent application number 202323109391.4 discloses a cooling machine for black tea production, including a cooling cylinder and an adjusting mechanism. The cooling cylinder has a control box at its front end, a cooling pipe at the left end of the front surface of the control box, a cooling fan in the middle of the cooling pipe, and adjusting columns fixedly connected to the rear ends of the outer surfaces of both sides of the cooling cylinder. The ends of the adjusting columns furthest from the cooling cylinder are rotatably connected to the upper ends of laterally adjacent supports. The supports are fixedly connected to a bracket via a mounting plate. The upper end of the bracket is fitted with the front end of the cooling cylinder. A fixed seat is located at the lower end of the cooling cylinder, a feed hopper is located at the upper end of the cooling cylinder, and a discharge port is located at the rear end of the cooling cylinder. The adjusting mechanism is located between the fixed seat and the mounting plate. The cooling machine also includes a control switch assembly located at the left end of the bracket. This cooling machine for black tea production effectively improves the efficiency of black tea cooling and makes black tea storage and retrieval more convenient.

[0004] The aforementioned patent describes a method of using multiple structures to stir black tea and accelerate cooling.

The cooling cylinder 1 and the cylinder cover 3 are connected by the auxiliary assembly 76.

[0024] By adopting the above technical solution, the forward and reverse stirring motor 72 is started to rotate forward. The forward and reverse stirring motor 72 drives the rotating shaft 73 to rotate. The rotation of the rotating shaft 73 will drive the horizontal stirring rod 74 and the vertical stirring rod 75 to rotate, thereby stirring the black tea.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is as follows: Specifically, the filter assembly 8 includes a filter tube 81, a support seat 82, a protective mounting cover 83, a filter cartridge 84, a positioning seat 85, a fastening screw 86, a rubber fastening block 87, and a rotating block 88. The filter tube 81 is fixedly connected above the cooling fan 5. The support seat 82 is fixedly connected to the lower part of the filter tube 81. The protective mounting cover 83 abuts against the upper part of the filter tube 81. The filter cartridge 84 is threadedly installed below the protective mounting cover 83, and the lower part of the filter cartridge 84 abuts against the support seat 82. The positioning seats 85 are fixedly connected to both sides of the protective mounting cover 83. One side of the positioning seat 85 abuts against the filter tube 81. The fastening screw 86 is threadedly connected to the middle of the positioning seat 85. One end of the fastening screw 86 is rotatably connected to the rubber fastening block 87. The rubber fastening block 87 and the positioning seat 85 are slidably connected. One side of the rubber fastening block 87 abuts against the filter tube 81. The other end of the fastening screw 86 is fixedly connected to the rotating block 88.

[0032] By adopting the above technical solution, when the cooling fan 5 is working, the air enters through the protective mounting cover 83 above the filter pipe 81, is filtered by the filter cartridge 84 to remove dust and impurities, and then enters the cooling fan 5. Finally, it is discharged into the cooling cylinder 1 to cool the black tea inside the cooling cylinder 1. Finally, the air is discharged from the feed hopper 4. When it is necessary to remove, clean or replace the filter cartridge 84, the rotating block 88 is turned. The rotating block 88 drives the fastening screw 86 to rotate. The rotation of the fastening screw 86 causes the rubber fastening block 87 to slide inside the positioning seat 85, so that the rubber fastening block 87 and the filter pipe 81 are separated. Then, the protective mounting cover 83 can be removed, and the filter cartridge 84 connected by the thread below the protective mounting cover 83 can be unscrewed for cleaning or replacement.

[0033] Specifically, the surface of the rotating block 88 is surrounded and fixedly connected with rubber protrusions, and the protective mounting cover 83 has a hole in the middle.

[0034] By adopting the above technical solution, the rubber protrusions facilitate the rotation of the rotating block 88, providing an anti-slip function, while the holes allow wind to enter through the protective mounting cover 83.

[0035] In this embodiment, when the cooling fan 5 is working, the air enters through the protective cover 83 above the filter pipe 81, is filtered by the filter cartridge 84 to remove dust and impurities, and then enters the cooling fan 5. Finally, it is discharged into the cooling cylinder 1 to cool the black tea inside the cooling cylinder 1. Finally, the air is discharged from the feed hopper 4. When it is necessary to remove, clean, or replace the filter cartridge 84, the rotating block 88 is turned. The rotating block 88 drives the fastening screw 86 to rotate. The rotation of the fastening screw 86 causes the rubber fastening block 87 to slide inside the positioning seat 85, so that the rubber fastening block 87 and the filter pipe 81 are separated. Then, the protective cover 83 can be removed, and the filter cartridge 84 connected to the thread below the protective cover 83 can be unscrewed for cleaning or replacement.

[0036] The structure and operating principle of the cooling cylinder 1, the feeding hopper 4, and the cooling fan 5 in this utility model have been disclosed in a cooling machine for black tea production disclosed in Chinese patent application number 202323109391.4. Its working principle is that the operator controls the operation of the cooling fan 5 by controlling the switch group. The cooling fan 5 introduces cold air into the interior of the cooling cylinder 1 through the cold air pipe to cool the black tea. Finally, the air is discharged through the feeding hopper 4.

[0037] The working principle and usage process of this utility model: This utility model is used in black tea production for cooling. During use, black tea is added to the cooling cylinder 1 through the feed hopper 4. The operator controls the cooling fan 5 via a switch assembly. The cooling fan 5 introduces cold air into the cooling cylinder 1 through a cold air pipe to cool the black tea. Finally, the air is discharged through the feed hopper 4. During cooling, the stirring assembly 7 stirs the black tea to accelerate the cooling rate. After cooling is complete, the valve of the discharge pipe 6 is opened to discharge the black tea. While the cooling fan 5 is working, the tea passes through a filter assembly... Component 8 filters the intake air. When the stirring assembly 7 is in use, the forward and reverse stirring motor 72 is started to rotate forward. The forward and reverse stirring motor 72 drives the rotating shaft 73 to rotate, which in turn drives the horizontal stirring rod 74 and the vertical stirring rod 75 to rotate, thereby stirring the black tea. In conjunction with the cooling fan 5, the black tea is cooled. By unscrewing the fixing screw 762, the cylinder cover 3 can be lifted through the handle 763 to remove the stirring component for inspection and maintenance. The positioning rod 761 facilitates the positioning of the cylinder cover 3 during installation. When the reversible stirring motor 72 rotates forward, it drives the spiral conveyor roller 764 to rotate forward via the rotating shaft 73, which can convey the black tea in the discharge pipe 6 upward for easy cooling. When the reversible stirring motor 72 rotates in reverse, it drives the spiral conveyor roller 764 to rotate in reverse via the rotating shaft 73, which can facilitate material discharge. This makes the device easy to stir and cool the black tea during use. The structure is simple and practical, which is beneficial to production. When the filter assembly 8 is in use, the cooling fan 5 is working. The air enters through the protective mounting cover 83 above the filter pipe 81 and is filtered by the filter cartridge 84 to filter out dust and impurities. Then it enters the cooling fan 5 and is finally discharged into the cooling cylinder 1 to cool the black tea in the cooling cylinder 1. Finally, the air is discharged from the feed hopper 4. When you want to remove, clean or replace the filter cartridge 84, turn the rotating block 88. The rotating block 88 drives the fastening screw 86 to rotate. The rotation of the fastening screw 86 causes the rubber fastening block 87 to slide inside the positioning seat 85, so that the rubber fastening block 87 and the filter tube 81 are separated. Then, the protective mounting cover 83 can be removed, and the filter cartridge 84 connected to the thread below the protective mounting cover 83 can be unscrewed for cleaning or replacement.
