Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a drying device for the production of refined tea. Background Technique

[0002] Refined tea is a tea-making process. Tea is a food with nutrition, rich fragrance and health-care functions, and is widely consumed by people. Some consumers drink raw tea, and some drink refined tea. Which one is more hygienic and safe, raw tea or refined tea? This experiment compares and analyzes refined tea and raw tea to distinguish their advantages and disadvantages.

[0003] In the production process of tea, the drying of tea is an important process in the production process. The main purpose is to use high temperature to destroy enzymes, stop enzymatic oxidation, evaporate moisture, shrink tea strips, fully dry the raw tea, prevent non-enzymatic oxidation, and facilitate maintaining the quality. It can emit the green odor and further improve and develop the aroma. Therefore, the drying device for the production of refined tea is essential.

[0004] The existing patent (publication number: CN214582331U) discloses a drying device for tea production and processing, including a main drying box body. Inside the main drying box body, two symmetrically distributed heating blocks are fixedly installed. Inside the main drying box body, four groups of evenly distributed bearings are fixedly installed. Inside two of the bearings, a driving roller is fixedly sleeved. For this drying device for tea production and processing, a conveying mechanism composed of a driving roller, a driven roller and a conveyor belt is fixedly installed inside the main drying box body, and a plurality of support plates for supporting a sieve frame are fixedly installed outside the conveyor belt. Driven by the power output of the motor, the conveying mechanism will convey the tea inside the sieve frame from the bottom to the top of the drying box. All tea raw materials experience the same drying process, avoiding placing sieve frames at different heights inside the drying box to dry tea, which may lead to problems such as difficult control of the drying time and easy confusion. The inventor found the following problems in the prior art during the implementation of the present utility model: 1. Most of the waste heat inside the traditional drying device is directly discharged outside the drying box, and the waste heat inside the drying box cannot be recycled, resulting in heat loss inside the drying box and causing the problem of insufficient utilization of energy; 2. The traditional drying device cannot turn the tea laid flat on the placement plate, resulting in the heating plate only being able to dry the tea on the surface of the placement plate, while the tea piled up at the bottom end inside the placement plate has a poor drying effect, resulting in uneven drying of the tea, and further significantly reducing the drying efficiency of the tea.

[0022] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a drying box body 101 , air suction covers 102 are arranged on both sides of the top of the drying box body 101 , and support seats 103 are arranged at the four corners of the bottom of the drying box body 101 .

[0023] In this embodiment, Figure 1 As shown, the two suction hoods 102 and the exhaust fan 14 are connected by a connecting pipe, so that the waste heat emitted from the drying box body 101 is absorbed and re-transmitted to the drying box body 101, which solves the problem of insufficient energy utilization caused by heat loss inside the drying box body 101, thereby realizing the recycling of the heat generated when the refined tea is dried.

[0024] In this embodiment, Figure 2 As shown, the toggle rod 13 and the positioning plate 12 are symmetrical about the central axis of the connecting shaft 10, which greatly improves the drying efficiency of the fine tea and makes the tea leaves evenly heated during the drying process, thus meeting the drying requirements for the production of fine tea.

[0025] In this embodiment, Figure 3 As shown, the sliding seat 7 and the slider 8 are provided with a sliding connection, so that the placement rack 9 can be quickly installed, and the convenience of the placement rack 9 during placement is greatly improved.

[0026] In this embodiment, Figure 3 As shown, the inner bottom end of the placement rack 9 is configured as a grid-like structure, so that the tea leaves at the inner bottom end of the placement rack 9 are heated more evenly, thereby greatly improving the drying effect of the fine tea.

[0029] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, first place the drying box main body 101 at the designated position through the support base 103, then lay the refined tea to be dried flat on the top of the placement rack 9. After closing the box door, preheat the heating plate 4 through the controller, so that the heat emitted by the heating plate 4 dries the refined tea at the top of the placement rack 9. At this time, start the motor 5 to drive the connecting shaft 10 to rotate. The connecting shaft 10 drives the two positioning plates 12 to rotate through the mounting seat 11. At this time, the two positioning plates 12 respectively drive the three toggle rods 13 to rotate synchronously. At the same time, the toggle rods 13 turn the tea leaves at the top of the placement rack 9, solving the problem that the tea leaves piled up at the bottom inside the placement rack 9 have poor drying effect, resulting in uneven drying of the tea leaves, thereby greatly improving the drying efficiency of the refined tea. The moisture absorption plate 2 can absorb the moisture in the hot air inside the drying box main body 101, greatly improving the dryness of the air inside the drying box main body 101. Then start the exhaust fan 14 to work through the controller, so that the dry hot air is transported to the inside of the air duct 15 through the connecting pipe under the action of the exhaust fan 14, and then is discharged back into the drying box main body 101 from the air outlet 16, realizing the absorption of the waste heat emitted inside the drying box main body 101 and re-transporting it to the inside of the drying box main body 101, solving the problem that the heat inside the drying box main body 101 is lost and the energy cannot be fully utilized, thereby realizing the recycling of the heat generated during the drying of the refined tea, and further meeting the drying requirements for refined tea production.
