Description

Technical Field

[0001] The utility model relates to the technical field of tea drying, in particular to energy-saving continuous tea drying equipment. Background Art

[0002] The tea processing process usually includes multiple steps such as withering, rolling, fermentation, and drying. Tea drying refers to the appropriate heat treatment of the newly picked tea leaves to make them lose some of their moisture and reduce the humidity in the tea leaves, thereby achieving the purpose of drying. In the process of tea drying, drying equipment is required.

[0003] The utility model patent with the authorization announcement number CN218034099U discloses a tea drying tower, which includes a tower box, the bottom four corners of the tower box are fixedly connected with supporting feet, a side of the tower box is provided with a plurality of notches in the vertical direction, the inner walls on both sides of the tower box are fixedly connected with support bars perpendicular to the notches and flush with the top surface, and a drying plate, the drying plate is supported and connected with the support bars after being inserted from the notches, the opposite side walls of the tower box are respectively provided with a plurality of air inlets and a plurality of air outlets, the outer side of the tower box is fixedly connected with an air inlet duct and the air inlet duct is connected with the air inlet duct, the outer side of the tower box is fixedly connected with an exhaust duct and the exhaust duct is connected with the air outlet duct. The utility model uses a drying plate to hold tea leaves to be dried, the drying plates are vertically distributed in the tower box, and after hot air is introduced, the tea leaves are dried in layers and sections, the drying efficiency is high, damage to the tea leaves can be avoided, the drying effect is good, and it can ensure that the tea leaves of each layer can be dried at the same time, ensuring that the tea leaves of each layer are dried evenly.

[0004] Although the tea drying tower is convenient for drying multiple layers of tea at the same time and can improve the efficiency of tea drying, the device still has the following problems in actual use: Specifically, when the tea leaves are placed on the drying tray, they tend to form a stacked state. During the drying process, the hot air follows the principle of natural rise, resulting in the bottom layer of tea receiving too much heat, while the top layer of tea is not heated enough. This uneven heat distribution phenomenon not only makes the drying effect of the tea uneven and affects the final quality, but also increases the overall energy consumption because additional time or heat energy is required to ensure that all tea leaves are dried evenly. In view of this, we propose an energy-saving continuous tea drying equipment. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] This embodiment provides a technical solution:

[0032] Please refer to Figures 1 - 5 As shown, the energy-saving continuous tea drying equipment includes two symmetric drying boxes 1. Two symmetric drying chambers 10 are provided in the drying box 1. A slag discharge port 101 is provided on one side wall of each drying chamber 10. A horizontally movable frame 11 is installed inside each drying chamber 10, and a screen 111 is installed inside the opening of the frame 11. An inclined guide plate 14 is also installed below the frame 11 in the drying chamber 10, and the end of the guide plate 14 extends to the slag discharge port 101. A plurality of drying tubes 4 are installed on the inner top of the drying chamber 10. A driving plate 15 is installed between the two frames 11 on the same horizontal plane. The end of the driving plate 15 is fixedly connected to the frame 11 by bolts. A main gear 16 is provided at the center of the driving plate 15. A driving shaft 161 is fixed on the main gear 16, and the bottom end of the driving shaft 161 is rotatably connected to the driving plate 15. Two sub-gears 17 are engaged on both sides of the main gear 16, and the two sub-gears 17 are parallel. A driven shaft 171 is fixed on the sub-gear 17, and the driven shaft 171 is rotatably connected to the driving plate 15. A motor 18 for driving the rotation of the driving shaft 161 is installed above the main gear 16;

[0033] Furthermore, collection boxes 3 for collecting residues are installed on the outer walls of the drying boxes 1 at the positions of the slag discharge ports 101. A connection groove 30 communicating with the slag discharge port 101 is provided on one side wall of the collection box 3, and a detachable cover plate 31 is installed at the top of the connection groove 30. The collection box 3 facilitates the collection of tea residues and is conducive to the subsequent treatment of tea residues.

[0034] In this embodiment, a protective cover 19 is fixedly connected between the two drying boxes 1 by bolts. The bottom of the protective cover 19 is open, and the driving plate 15 is located inside the protective cover 19. The protective cover 19 plays a protective role for the main gear 16, the sub-gears 17, and the driving plate 15.

[0035] In this embodiment, a rotatable door 2 is installed on the front end face of the drying box 1, and the door 2 is hinged to the drying box 1 through a hinge. The setting of the door 2 facilitates the closing of the drying box 1 and is conducive to maintaining heat during drying.

[0036] In this embodiment, side plates 12 are installed at both ends of the bottom of the frame 11; two guide rods 13 are fixed in the drying chamber 10, and the guide rods 13 pass through the side plates 12 and are slidably connected to the side plates 12. The arrangement of the guide rods 13 plays a guiding role in the horizontal movement of the frame 11, ensuring the smoothness and stability of the horizontal movement of the frame 11.

[0037] In this embodiment, the cross-sectional shape of the frame 11 is in a square shape with an opening in the middle, and the frame 11 is fixedly connected to the screen 111 by bolts. The bolt fixation method ensures the reliability of the installation of the frame 11 and the screen 111, and the square shape with an opening in the middle is convenient for installing the screen 111.

[0038] In this embodiment, the material guiding plate 14 is fixedly connected to the drying box 1 by bolts, and the material guiding plate 14 is inclined towards the slag discharge port 101. The bolt fixation method ensures the reliability of the installation of the material guiding plate 14, and the inclined design facilitates the convergence of tea residues into the collection box 3.

[0039] In this embodiment, a protrusion is provided at the front end of the material guiding plate 14, and the protrusion and the material guiding plate 14 are of an integrally formed structure. The provision of the protrusion can prevent tea residues from falling from the front end of the material guiding plate 14, avoiding the scattering of tea residues to the outside. The integrally formed structure has better structural strength, ensuring the service life of the material guiding plate 14.

[0040] It should be added that the main gear 16 and the driving shaft 161 in this embodiment are eccentrically installed, and the secondary gear 17 and the driven shaft 171 are eccentrically installed. When the main gear 16 rotates, the main gear 16 will drive the secondary gears 17 on both sides to rotate, and the secondary gears 17 will perform circular motion with the driven shaft 171 as the center. At this time, the driving plate 15 can be driven to perform horizontal reciprocating motion, thereby facilitating the driving of the frames 11 on both sides to perform continuous horizontal motion.

[0041] It is worth noting that the motor 18 involved in this embodiment is an existing conventional technology and will not be elaborated here.

[0042] During specific use, the user first turns on the power supplies of the motor 18 and the drying lamp tubes 4. The motor 18 and the drying lamp tubes 4 start to work. The output shaft of the motor 18 rotates to drive the driving shaft 161 and the main gear 16 to rotate. Since the main gear 16 meshes with the secondary gears 17 on both sides, the secondary gears 17 rotate. As the secondary gears 17 rotate, the driving plate 15 synchronously performs horizontal reciprocating motion. The driving plate 15 simultaneously drives the frames 11 on both sides to perform horizontal reciprocating motion. As the frames 11 move, the tea leaves roll on the screen 111. At the same time, the tea residues fall onto the material guiding plate 14 and enter the collection box 3 through the slag discharge port 101. At the same time, the drying lamp tubes 4 dry the tea leaves on the screen 111.
