Technical Field

[0001] The utility model discloses a tea uniform drying machine, belonging to the field of tea processing. Background Art

[0002] Tea processing refers to the process of making finished tea after the fresh leaves of tea trees are harvested through various processes. For example, the processing technology of green tea is killing, rolling, and drying; the processing technology of black tea is withering, rolling, fermentation, and drying. Tea drying is the last process of tea processing. Its main purpose is to lose the moisture of tea leaves, shape tea leaves, and increase the aroma of tea leaves. The quality of drying directly affects the quality of tea leaves.

[0003] Existing tea drying methods are divided into manual and machine drying. Although manual drying can stir-fry tea leaves, it is time-consuming and labor-intensive. Machine drying generally uses a rolling dryer, which easily causes tea leaves to pile up into clumps. The clumped tea leaves are not easy to disperse, which easily affects the drying effect.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, a tea uniform drying machine includes a drying chamber 1 and a hot air blower 2 connected to the drying chamber 1, the drying chamber 1 includes a base 3 and a cover 4 detachably connected to the base 3, a placement component for placing materials is arranged in the base 3, the placement component includes a rotating shaft 5 rotatably arranged on both sides of the base 3 and a placement belt 6 wound on the rotating shaft 5, a driving device is arranged in the base 3, and the driving device can cause the placement belt 6 to reciprocate and deform.

[0022] When using this product, open the lid 4, then put the tea leaves to be dried on the placement belt 6, then cover the lid 4 and start the machine. After the machine is started, the hot air blower 2 will send the hot air required for drying the tea leaves into the drying chamber 1, and the driving device starts to run, causing the placement belt 6 to deform back and forth, thereby giving the tea leaves on the placement belt 6 an initial velocity, causing the tea leaves to be thrown up, achieving an effect similar to frying the tea leaves, thereby preventing uneven drying caused by accumulation of tea leaves.

[0023] For example Figure 4As shown, the driving device includes a driving motor 7 and a reciprocating mechanism 8. The driving motor 7 is installed in the base 3. The reciprocating mechanism 8 includes a support 9, a gear assembly 10 and a push rod 11. The support 9 is fixedly connected to the base 3, the gear assembly 10 is movably connected to the support 9, the push rod 11 is movably arranged in the support 9, one end of the push rod 11 is transmission-connected to the gear assembly 10, a reinforcing rib 12 is fixedly connected to the middle of the placement belt 6, and the other end of the push rod 11 is fixedly connected to the reinforcing rib 12. The gear assembly 10 includes a clamping plate 13, a first gear 14 and a second gear 15. The first gear 14 is meshed with the second gear 15, and the first gear 14 and the second gear 15 are respectively rotatably connected to the clamping plate 13. A first boss 16 is eccentrically provided on the first gear 14, and one end of the push rod 11 close to the first gear 14 is sleeved on the first boss 16. A second boss 17 is eccentrically provided on the second gear 15. One end of the support 9 close to the second gear 15 It is sleeved on the second boss 17, and the output end of the driving motor 7 is transmission connected with the second boss 17. When the driving motor 7 is running, the output end of the driving motor 7 will drive the second boss 17 to rotate. Since the second boss 17 is eccentrically arranged on the second gear 15, the second gear 15 will drive the first gear 14 to move eccentrically. Because the first boss 16 is eccentrically arranged on the first gear 14, and one end of the push rod 11 is sleeved on the first boss 16, the first boss 16 will push the push rod 11 to make it reciprocating linear motion along the support 9. Since the other end of the push rod 11 is fixedly connected to the reinforcing rib 12, the push rod 11 will pull the reinforcing rib 12 to perform reciprocating linear motion, and at the same time drive the placement belt 6 to reciprocate deformation. In the process of resetting after the placement belt 6 is deformed, an initial velocity will be given to the tea leaves, so that the tea leaves are thrown up, achieving an effect similar to frying tea leaves, preventing the tea leaves from piling up, and making the tea leaves dried more evenly.

[0024] A torsion spring is arranged between the rotating shaft 5 and the base 3 of this product. The torsion spring can drive the rotating shaft 5 to rotate and twist the torsion spring to store force when the placement belt 6 is pulled down, so that the placement belt 6 can be better wound to its original state when the placement belt 6 is reset, thereby improving the stability of the equipment operation.

[0025] like Figure 5 As shown, a plurality of fine holes 18 are provided on the placing belt 6, and a plurality of air inlets 19 are provided on the drying chamber 1. The air inlets 19 are connected to the output end of the hot air blower 2, and the air inlets 19 are symmetrically arranged relative to the placing belt 6. This design allows hot air to enter both the upper and lower parts of the placing belt 6 at the same time. When drying the tea leaves above the placing belt 6, due to the principle of hot air floating, the hot air below the placing belt 6 will also pass through the fine holes 18 provided on the placing belt 6 to dry the tea leaves from below, thereby making the drying of the tea leaves more uniform.

[0026] Finally, a partition plate 20 is provided in the base 3, and the partition plate 20 cooperates with the lower bottom of the base 3 to form a cavity. The drive motor 7 is specifically installed in the cavity. The partition plate 20 can play a heat insulating role, so that the operating environment of the drive motor 7 will not overheat, thereby improving the stability of the equipment.
