Description

Technical Field

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

[0002] Tea drying plays multiple roles in tea production, primarily including the following: First, removing moisture is one of the main purposes of tea drying. Tea contains a high moisture content, and without drying, it is prone to mold growth, affecting its preservation and aging. Drying can significantly reduce the moisture content of tea, extending its shelf life. Second, altering the chemical composition is also an important function of drying. During the drying process, the enzyme activity in tea decreases. Furthermore, drying can improve the aroma and taste of tea, making it fuller and sweeter.

[0003] In existing technologies, tea leaves are generally placed in a vertical dryer, and the leaves are dried by the horizontal rotation of a turntable inside the dryer. Although this method improves the uniformity of drying to some extent, the tea leaves themselves do not tumble when the turntable rotates, so the effect of drying the tea leaves evenly is not ideal.

[0004] In view of this, the present invention provides a drying machine for tea production to solve the above problems. Utility Model Content

[0005] To solve the above problems, this utility model provides the following technical solution: a dryer for tea production, including a base, a roller rotatably connected to the base, and a drive assembly installed on one side of the base for driving the roller to rotate. The roller has a hollowed-out wall structure for loading the material to be dried. When it rotates, the material to be dried tumbles at the bottom inside the roller. The base is equipped with a hot air generator whose output end faces the axis of the roller. During drying, the hot air generator blows hot air to dry the material to be dried tumbling inside the roller.

[0006] As a preferred embodiment of the dryer for tea production according to this utility model, an air guide tube is also provided between the hot air generating device and the drum to guide the hot air into the drum.

[0007] As a preferred embodiment of the present invention for a drying machine used in tea production, the base has opposing uprights, the roller is rotatably connected between the uprights, and the side of the upright has a transverse through hole, the inside of which a bearing is fitted for connection with both ends of the roller.

[0008] As a preferred embodiment of the dryer for tea production according to this utility model, the surface of the base is also equipped with a control panel, which is electrically connected to the hot air generating device and the drive assembly.

[0009] As a preferred embodiment of the dryer for tea production according to this utility model, the two ends of the drum are respectively provided with a first connecting shaft and a second connecting shaft. The first connecting shaft and the second connecting shaft are coaxially arranged with the drum and are used to be inserted and fixed with the inner ring of the bearing.

[0010] As a preferred embodiment of the dryer for tea production according to this utility model, the drive assembly includes: a motor and a reducer connected to the output end of the motor.

[0011] As a preferred embodiment of the dryer for tea production according to this utility model, the reducer is installed on one side of the upright frame, and its output end is keyed to the second connecting shaft.

[0012] As a preferred embodiment of the dryer for tea production according to this utility model, the surface of the drum body is also provided with a material inlet for the material to be dried to enter and exit. A drum door is hinged inside the material inlet, and a lock is provided between the drum door and the material inlet. The drum door is fixed to the material inlet by the lock to close the material inlet.

[0013] As a preferred embodiment of the dryer for tea production according to this utility model, the inner wall of the drum is connected with axially arranged lifting ribs, which are evenly distributed axially on the inner wall of the drum.

[0014] As a preferred embodiment of the dryer for tea production according to this utility model, the lifting ribs are further provided with arc-shaped protrusions on the opposite surface of the roller axis. The protrusions are inclined and arranged at axial intervals.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention uses a rotating drum to allow the tea leaves to tumble inside the drum during drying, thereby increasing the contact area between each tea leaf and the hot air and improving the uniformity of drying.

[0017] Secondly, by setting up lifting ribs and protrusions, the tea leaves can be lifted to a certain height when the drum rotates, and then the protrusions will scatter the tea leaves and let them fall, thereby further ensuring that each tea leaf is fully in contact with the hot air and further improving the uniformity of tea drying.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model relates to a drying machine for tea production, such as... Figure 1 As shown, it includes: a base 1, a hollow roller 2 rotatably connected to the base 1, and a drive assembly 3 installed on one side of the base 1 for driving the roller 2 to rotate. At least one hot air generator 4 is vertically embedded inside the base 1. The output end of the hot air generator 4 is directly opposite the axis of the roller 2 to better output hot air. In this embodiment, the hot air generator 4 is preferably an electric heating fan.

[0028] Among them, such as Figure 2 As shown, a control panel 15 is mounted on the surface of the base 1. The control panel 15 is connected to an external power source and electrically connected to the drive assembly 3 and the hot air generator 4 to control the operation of the drive assembly 3 and the hot air generator 4. Support legs 14 are provided at the four corners of the bottom surface of the base 1. The support legs 14 support the base 1, creating a gap between the bottom surface of the base 1 and its placement surface to allow for high-intensity air intake of the hot air generator 4.

[0029] The base 1 also has a support frame 11 arranged opposite to each other. A through hole 12 is opened on the side of the support frame 11, and a bearing 13 is also fitted in the through hole 12. The two ends of the roller 2 are respectively fixedly connected to a first connecting shaft 21 and a second connecting shaft 22. The first connecting shaft 21 and the second connecting shaft 22 are respectively inserted into the inner ring of the bearing 13 fitted in the through hole 12, so that the roller 2 is horizontally and rotatably mounted between the two supports 11.

[0030] Furthermore, the drive assembly 3 includes a motor 31 and a reducer 32 connected to the output end of the motor 31. The reducer 32 is installed on one side of the stand 11 and its output end is keyed to the second connecting shaft 22. When the motor 31 is running, the reducer 32 can drive the second connecting shaft 22 to rotate circumferentially, thereby driving the roller 2 to rotate.

[0031] Furthermore, the surface of the drum 2 is provided with a feed inlet (not marked in the figure), and a drum door 23 is hinged inside the feed inlet. By opening the drum door 23, the items to be dried can be placed inside the drum 2 or taken out from the drum 2. A lock (such as a bolt, a latch, etc.) is installed between the hinged opposite side of the drum door 23 and the feed inlet. The drum door 23 can be closed by the lock to prevent the items to be dried from falling out of the feed inlet when the drum 2 rotates.

[0032] Furthermore, such as Figures 3-4 As shown, the inner wall of the drum 2 is also connected with an axially arranged lifting rib 24. In this embodiment, the lifting rib 24 is square and perpendicular to the tangent direction of the inner wall of the drum 2, thus forming an "L"-like structure with the inner wall of the drum 2. When the drum 2 rotates, the lifting rib 24 can conveniently lift part of the material to be dried inside the drum 2 to a certain height.

[0033] In addition, such as Figure 5 As shown, on the surface opposite to the axis of the lifting rib 24 and the roller 2, there are arc-shaped protrusions 25 arranged axially evenly. When the lifting rib 24 lifts the item to be dried, the item can be broken up by the protrusions 25 during its descent, thereby further increasing the contact area between the item and the hot air, achieving efficient and uniform drying. Figure 6 As shown, the protrusion 25 is inclined inward from both ends of the lifting rib 24, so that when the protrusion 25 disperses the material to be dried, it can further gather the material to be dried towards the center of the bottom surface of the drum 2 for better heating.

[0034] Furthermore, in order to enable the hot air blown out by the hot air generator 4 to act directly on the drum 2, an air guide duct 5 can be installed between the hot air generator 4 and the drum 2. One end of the air guide duct 5 is connected to the air outlet of the hot air generator 4, and the other end is close to the bottom of the drum 2. When the hot air is blown out, the air guide duct 5 can directly guide the hot air into the inside of the drum 2, effectively reducing the consumption of hot air.

[0035] In use, taking tea production as an example: pour the tea leaves into the drum 2, and then start the hot air generator 4 and motor 31 through the control panel 15. At this time, the drum 2 rotates, causing the tea leaves to tumble at the bottom of the drum 2 and continuously come into contact with the hot air. At the same time, under the action of the lifting ribs 24, the tumbling action of the tea leaves is further improved, so that the tea leaves can better come into full contact with the hot air. Under the action of the protrusions 25, the tea leaves fall alternately and are fully dispersed, thereby achieving fast, efficient and uniform drying of the tea leaves.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
