Description

Technical Field

[0001] This utility model relates to the field of drum-type blanching technology, and in particular to a drum-type blanching machine with grading function. Background Technology

[0002] In tea processing, the core of fixing is to destroy enzyme activity to stabilize quality, while grading is to distinguish tea grades according to particle size to improve the adaptability of subsequent processing. Both are key processes. In the traditional tea processing process, fixing and grading rely on independent equipment and lack integrated design, resulting in low processing efficiency and difficulty in quality control. Traditional processing involves two steps: First, fresh leaves are fed into a separate drum-type fixing machine to complete the fixing process. After fixing, the tea leaves are collected from the machine's outlet and placed into a transfer basket. Second, the tea leaves in the transfer basket are manually or mechanically transported to a separate grading device for grading. Throughout this process, material transfer requires multiple manual interventions, each transfer is time-consuming, and tea leaves are prone to spillage during transfer, resulting in raw material waste. At the same time, the processing rhythms of the fixing machine and the grading device are difficult to synchronize, which can easily lead to the accumulation of tea leaves after fixing, waiting for grading. This severely restricts the overall processing efficiency and cannot meet the needs of large-scale production. Therefore, these problems need to be solved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4This utility model discloses a grading-function drum-type tea-fixing machine, including a base 1, with a shell 2 fixedly connected to the top surface of the base 1. The shell 2 facilitates a closed structure to reduce heat loss and improve tea-fixing efficiency. A first drum 3 is rotatably mounted inside the shell 2, which facilitates preliminary grading and provides an installation base for the electric heating tube 13. Two rotating seats are symmetrically fixedly connected to one end of the top of the base 1, and a discharge block is fixedly connected to the other end of the top of the base 1. One side of the discharge block is welded to one end of the shell 2. A first gear 4 is fixedly connected to the outer wall of the feed end of the first drum 3, which facilitates stable rotation speed of the first drum 3 and uniform tea-fixing time. A grading component is fixedly connected to the outer wall of the discharge end of the first drum 3.

[0015] In this invention, the grading component includes a second roller 7 fixed to the outer wall of the discharge end of the first roller 3 and a third roller 9 fixed to the outer wall of the second roller 7. The outer walls of the first roller 3 and the second roller 7 are respectively provided with multiple first sieve holes 6 and second sieve holes 8 of different sizes. The grading component facilitates the formation of a gradient grading system, enabling the simultaneous classification of tea leaves of different particle sizes during the tea fixing process. The inner walls of the first roller 3, the second roller 7, and the third roller 9 are sequentially fixed with matching spiral guide plates 5. An electric heating tube 13 is sleeved on the outer wall of the other end of the first roller 3, allowing for precise control of the fixing temperature to meet the fixing requirements of different tea leaves. A discharge port is provided at the top of the discharge block. Three discharge plates 14 adapted to the grading components are sequentially fixed to the inner wall of the discharge port. The discharge plates 14 are inclined and facilitate independent zoning, guiding the tea leaves to be discharged in categories and avoiding mixing of tea leaves of different particle sizes. A motor 11 is installed on the inner wall of the other end of the outer shell 2. The output end of the motor 11 extends to the outer wall of the outer shell 2 and is coaxially fixed to a second gear 12. The second gear 12 meshes with the first gear 4. The motor 11 facilitates the driving of the first roller 3 and the grading components to rotate. A support roller 10 is rotatably provided on the rotating seat to assist in supporting one end of the first roller 3. The support roller 10 facilitates the support of the feed end of the first roller 3, reduces the friction when the roller rotates, and ensures the smooth operation of the roller.

[0016] Working Principle: In the use of this utility model, firstly, each electrical component in this application is connected to the power source. Then, according to the variety and moisture content of the tea to be processed, the heating power of the electric heating tube 13 and the rotation speed of the first drum 3 are set through the control system. The electric heating tube 13 is sleeved on the outer wall of the first drum 3. After starting, it heats the inner wall of the drum through heat conduction, raising the temperature inside the drum to the target fixing temperature. At the same time, the rotation speed of the motor 11 is adjusted to ensure that the fixing time of the tea is matched with the moving speed. Then, the operator puts the tea to be fixed into the feed end of the first drum 3 and starts the motor 11. The output end of the motor 11 drives the second gear 12 to rotate. The second gear 12 meshes with the first gear 4 at the feed end of the first drum 3, driving the first drum 3 and the second drum 7 and third drum 9 on the outer wall to rotate synchronously. The spiral guide plate 5 on the inner wall of the first drum 3 rotates with the drum, pushing the tea to move at a uniform speed along the axial direction. During the process, the tea comes into full contact with the high-temperature inner wall of the drum, achieving preliminary fixing, destroying the enzyme activity in the tea, and preventing the tea from oxidizing and deteriorating. Then, the three-stage gradient grading operation is carried out, and the tea leaves are processed. As the tea leaves move within the first drum 3, small-diameter tea leaves are sieved through the evenly distributed first screen holes 6 on the outer wall of the drum and fall into the corresponding discharge plate 14 below, completing the initial grading and preventing over-processing of small-diameter tea leaves due to prolonged heating. Tea leaves that do not pass through the first screen holes 6 enter the second drum 7 connected to the discharge end of the first drum 3 along with the spiral guide plate 5. The second drum 7 rotates synchronously, and the second screen holes 8 on its outer wall sieve out medium-diameter tea leaves, which fall into the corresponding discharge plate 14, achieving secondary grading and further distinguishing the tea leaf size. Large-diameter tea leaves that do not pass through the second screen holes 8 enter the third drum 9 on the outer wall of the second drum 7. The third drum 9 has no additional screen holes, and only the spiral guide plate 5 on its inner wall transports the large-diameter tea leaves to the end, where they fall into the corresponding discharge plate 14. Finally, the small, medium, and large-diameter tea leaves that have undergone tertiary grading slide out of the discharge port along three independent inclined discharge plates 14. Operators can place different collection containers below the discharge port to achieve classified collection of tea leaves and avoid secondary mixing of tea leaves after grading. This concludes the use of a drum-type tea-processing machine with grading function.
