Description

Technical Field

[0001] This utility model relates to the field of flower tea production, specifically to a low-temperature drying and preservation device for flower tea. Background Technology

[0002] Scented tea, also known as fragrant tea, is a type of reprocessed tea unique to China, made by steeping the flowers, leaves, or fruits of plants. It utilizes tea's ability to absorb odors; fragrant fresh flowers and fresh tea leaves are steeped together, allowing the tea to absorb the aroma. The dried flowers are then removed, resulting in a mature scented tea with a rich aroma and a deep color. Scented tea can be further subdivided into herbal tea and fruit tea.

[0003] Current low-temperature drying and preservation equipment for flower tea, as described in patent CN220771749U, includes a low-temperature drying chamber. A partition plate is fixedly installed in the lower center of the chamber. A first limiting groove is formed in the middle of the top surface of the partition plate. A fixed rotating shaft is rotatably installed in the middle of the first limiting groove. A placement mechanism is rotatably installed on the top surface of the fixed rotating shaft. The top surface of the placement mechanism is connected to the rotating shaft, which is driven by a drive motor. The placement mechanism includes a placement frame. A placement frame door is rotatably installed on one side of the front surface of the placement frame via a hinge. The placement frame and the placement frame door are connected by multiple fixing mechanisms.

[0004] Regarding the aforementioned technologies, the inventors believe that since the flowers, leaves, or fruits of plants used to prepare different flower teas are of different sizes, and the spacing between two adjacent placement troughs is fixed, if the flowers, leaves, or fruits of plants used to prepare flower teas are small in size, a large amount of space between two adjacent placement troughs cannot be fully utilized. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature drying and preservation device for flower tea to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-4 A low-temperature drying and preservation device for flower tea includes a drying mechanism 1, which includes a drying chamber 101. A door 102 is rotatably connected to one side of the drying chamber 101, and the door 102 is configured to close the drying chamber 101. A heat inlet pipe 103 is fixedly installed through one side of the top of the drying chamber 101, and an exhaust pipe 104 connected to the interior of the drying chamber 101 is fixedly connected to the other side of the top of the drying chamber 101. The heat inlet pipe 103 is configured to connect to a hot air blower, so that the hot air blown by the hot air blower can be guided into the interior of the drying chamber 101 to provide a heat source for the low-temperature drying of flower tea.

[0024] The drying oven 101 has rotating frames 105 rotatably connected to both its upper and lower sides. A drive motor 106 is fixedly connected to the top of the drying oven 101, and the output end of the drive motor 106 is fixedly connected to the upper rotating frame 105. The drive motor 106 is configured to drive the upper rotating frame 105 to rotate during startup. Support plates 107 are symmetrically fixedly connected between the two sets of rotating frames 105, allowing them to rotate synchronously. Multiple support rods 109 are fixedly connected in a circular array at the bottom of the lower rotating frame 105. Each set of support rods 109 has a ball bearing 110 movably connected to its bottom. The support rods 109 and the ball bearings 110 provide auxiliary support for the lower rotating frame 105.

[0025] The adjustment mechanism 2 includes limiting grooves 201 evenly spaced on opposite sides of two sets of support plates 107. Multiple trays 108 are positioned between the two sets of support plates 107. Each tray 108 has multiple through holes 111 evenly spaced inside. The trays 108 are used to hold and contain the flower tea to be dried at low temperatures. Each set of trays 108 has a symmetrically fixed insert block 202 on its outer side. The insert block 202 is inserted into the limiting groove 201, which limits the insertion of the insert block 202, allowing it to be inserted into the limiting groove 201 at different heights, thereby adjusting the installation distance between adjacent trays 108.

[0026] The bottom of the insert block 202 is movably connected with ball bearings 203. Each set of ball bearings 203 contacts the inner wall of the limiting groove 201. The ball bearings 203 reduce the friction between the insert block 202 and the inner wall of the limiting groove 201. The bottom of the lower tray 108 is provided with a baffle 204. The baffle 204 is used to block the through holes 111 on the bottom tray 108, so that the bottom tray 108 can be used as a receiving tray to catch tea crumbs falling from the upper trays 108. The baffle 204 is symmetrically fixed with studs 205 inside, and the studs 205 pass through the through holes 111. Nuts 206 are threadedly connected to the outside of the studs 205. The nuts 206 and studs 205 are used to limit and fix the baffle 204.

[0027] A limiting plate 208 is fixedly connected to one side between the two sets of rotating frames 105. The limiting plate 208 has a through opening 210 inside. Each set of trays 108 is rotatably connected to a rotating shaft 207. Each set of rotating shafts 207 passes through the through opening 210. The through opening 210 is provided for the rotating shaft 207 to pass through, so that when the limiting plate 208 rotates with the rotating frame 105, the rotating shaft 207 and the tray 108 can be moved to rotate accordingly.

[0028] Each set of rotating shafts 207 has a stop 209 fixedly connected to one end. The stop 209 is used to limit the movement of the rotating shaft 207 and the tray 108. The width of the stop 209 is smaller than the width of the through opening 210, and the length of the stop 209 is greater than the width of the through opening 210, so that the stop 209 can pass through the through opening 210 when it is rotated to a vertical position. Each set of rotating shafts 207 has a lever 211 fixedly connected to the other end. A torsion spring 212 is fixedly connected between the lever 211 and the tray 108. The torsion spring 212 is used to drive the lever 211, the rotating shaft 207 and the stop 209 to rotate using its elasticity, thereby keeping the stop 209 in a horizontal state.

[0029] In use, the flower tea to be dried is spread evenly inside each set of trays 108. Then, the chamber door 102 is closed, and one end of the heat inlet pipe 103 is connected to the output end of the hot air blower. After that, the chamber door 102 is closed again, and the hot air blower is started, so that the hot air blower can discharge 40-60℃ into the heat inlet pipe 103 when it starts working. Then, the air is discharged into the drying chamber 101 through the guide of the heat inlet pipe 103, thereby drying the flower tea inside the drying chamber 101 at a low temperature. At the same time, the drive motor 106 can be started, so that the drive motor 106 can drive the rotating frame 105, the support plate 107 and the limiting plate 208 to rotate when it starts working. The limiting plate 208 rotates... The rotating shaft 207 and each set of trays 108 can be rotated to ensure that the flower tea on the trays 108 is heated evenly, thereby improving the effect of low-temperature drying of the flower tea. After the flower tea has been dried at low temperature, the door 102 can be opened, and then a set of levers 211 can be rotated to drive the rotating shaft 207 and the corresponding stop block 209 to rotate until the stop block 209 is adjusted to a vertical position. Then, the corresponding tray 108 can be moved away from the inside of the drying chamber 101 so that the corresponding stop block 209 passes through the through opening 210 until the corresponding tray 108 is removed from the inside of the drying chamber 101. Then, the low-temperature dried flower tea can be poured out.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
