Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a multi-stage dehumidification and drying device for tea. Background Technology
[0002] Tea is an important economic crop in my country, and its processing quality directly determines the commodity value of the product. Dehumidification and drying are key processes in tea processing. Fresh tea leaves have a high moisture content after picking. If the moisture is not removed in a timely and proper manner, it will not only lead to mold and rot, causing economic losses, but also cause excessive enzymatic reactions, damaging the aroma substances, tea polyphenols, and other core components of the tea, thus affecting the color, aroma, and taste of the final product.
[0003] However, existing tea dehumidification and drying devices still have certain shortcomings. For example, traditional devices are mostly single-stage drying structures, which only complete dehumidification by heating and blowing air once, resulting in low drying efficiency and difficulty in completely removing moisture from the tea leaves. Although multi-stage drying can be achieved by manually repeatedly turning the leaves over, it is labor-intensive and cumbersome to operate. Secondly, the devices have limited functions and can only perform drying operations. They cannot simultaneously separate impurities such as broken leaves and dust mixed in during tea picking and initial processing, requiring an additional sorting process, which increases the complexity of the production process.

The inner diameter of the through hole 15 is larger than the outer diameter of the bolt 16, which facilitates the installation and fixing of the filter screen 13. The through hole 15 corresponds to the threaded hole 17, which facilitates the installation of the filter screen 13.
[0029] Reference Figure 2 and Figure 3 The conveying assembly includes a connecting box 20 fixedly connected to the outer surface of the processing box 1, a material conveying hole 21 opened on the outer surface of the connecting box 20, a motor B22 fixedly connected to the outer surface of the connecting box 20, a conveyor roller A23 fixedly connected to the output end of the motor B22, a conveyor roller B24 rotatably connected to the inside of the connecting box 20 via bearings, a conveyor belt 25 drivingly connected to the outer surfaces of the conveyor roller A23 and the conveyor roller B24, and multiple inclined plates 26 fixedly connected to the outer surface of the conveyor belt 25. The outer surface of the processing box 1 is also provided with two symmetrically distributed material conveying holes 21 that communicate with the material conveying hole 21 on the outer surface of the connecting box 20 to facilitate the conveying of tea leaves.

[0030] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0031] Working principle: During operation, the power is turned on, and the heating element 9 is heated by the temperature controller 10. Then, motors A5 and B22 are started. Under the action of motor A5, the rotating shaft 6 drives the fan blades 7 to blow air onto the heating element 9, thereby drawing in external air through the air hole 3 and blowing it onto the heating element 9 for heating. Then, the air is blown horizontally into the processing chamber 1. The tea leaves to be dried are poured into the processing chamber 1 through the opening at the top of the processing chamber 1 and slide down the guide plate 11. When the tea leaves pass through the area blown by the horizontal hot air, the moisture on the surface of the tea leaves is carried away, thereby achieving the drying operation. When the tea leaves fall onto the filter screen 13 inside the processing chamber 1, the impurities and debris in the tea leaves will fall into the drawer 19 for collection under the filtering effect of the filter screen 13. The tea leaves on the filter screen 13 will slide down the inclined surface of the filter screen 13 to the lower feed hole 21 and finally enter the conveying chamber inside the connecting box 20. Under the action of motor B22, the conveyor rollers A23 and B24 are driven to rotate the conveyor belt 25. The conveyor belt 25 then drives multiple inclined plates 26 to transmit the tea leaves that have fallen into the conveying chamber of the connecting box 20 to the upper feeding hole 21. Under the inclination of the inclined plates 26, the tea leaves slide back into the processing box 1. Then, guided by the guide plate 11, they slide back into the processing box 1 for drying again. This process is repeated to effectively remove moisture and impurities from the tea leaves. When the tea leaves have reached the required dryness, the power is turned off, the drawer box 19 is pulled out along the inside of the dropping trough 18 and the internal impurities and debris are poured out. Then, the cleaned drawer box 19 is reinserted into the dropping trough 18. At the same time, the bolts 16 are loosened and removed to release the restriction on the limiting plate 14. Then, the filter screen 13 is pulled out along the inside of the slot 12, allowing the dried tea leaves to fall into the drawer box 19 for collection and storage.
