Description

Technical Field

[0001] The utility model relates to the field of tea machines, and particularly relates to a drum tea-leaf withering machine. Background Art

[0002] The withering effect of the drum tea-leaf withering machine is closely related to the moisture exhaust performance of the equipment. Moisture exhaust means discharging the moisture generated during the withering of tea leaves from the drum, so as to ensure the color and quality of the tea leaves. The traditional moisture exhaust mechanism is to set an air supply pipe at the feeding end of the drum, and the air distributed through the air supply pipe carries the generated moisture out of the drum. Due to the traditional moisture exhaust mechanism, only one air supply pipe is provided, and its moisture exhaust performance is limited. Therefore, in order to further improve the processing quality of tea leaves, it is necessary to solve this problem. Content of the Utility Model

[0003] To solve the above problems, the utility model provides an air distribution mechanism for a drum tea-leaf withering machine, which can effectively distribute hot air into the drum and improve the withering effect of the tea leaves in the drum.

Detailed Embodiment

[0021] In order to make the purpose and advantages of the utility model more clear, the following describes the utility model in detail with reference to the embodiments. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the specific protection scope claimed by the utility model.

[0022] Such as Figure 1 、2 As shown in the figure, a drum green tea fixing machine includes a drum rotatably installed on a frame 10. A heating device for heating the drum is provided below the drum. A first air flow unit and a second air flow unit are provided at the feeding end of the drum. The first air flow unit and the second air flow unit respectively supply air flows into the drum. The first air flow unit is arranged corresponding to the material area inside the drum, and the second air flow unit is arranged corresponding to the empty material area inside the drum. The material area is the area where the tea leaves are located inside the drum during the green tea fixing process, and the empty material area is the area arranged opposite to the material area inside the drum. The air flow rate supplied by the first air flow unit is greater than that supplied by the second air flow unit. Through the reasonable distribution of the air flow, since a large amount of moisture will be generated due to the concentration of tea leaves in the material area, the first air flow unit with a larger air flow rate is used to arrange the air flow, while there is no tea in the empty material area, and the second air flow unit with a smaller air flow rate is used to arrange the air flow, so that the moisture inside the drum can be reliably discharged, improving the green tea fixing effect.

[0023] A further solution is that the air flows supplied by the first air flow unit and the second air flow unit are hot air flows. It further includes a third air flow unit for supplying air flow into the drum, and the third air flow unit is arranged corresponding to the top area inside the drum. The air flow rate supplied by the third air flow unit is less than that supplied by the first air flow unit. The specific operation is as follows: An annular mounting plate 28 is provided outside the feeding end of the drum. The first air outlet pipe 21 constituting the first air flow unit, the second air outlet pipe constituting the second air flow unit, and the third air outlet pipe constituting the third air flow unit are respectively fixedly installed on the annular mounting plate 28. The air outlet directions of the first air outlet pipe 21, the second air outlet pipe, and the third air outlet pipe are all consistent with the length direction of the drum. Two first air outlet pipes 21 are provided, and one second air outlet pipe and one third air outlet pipe are respectively provided, specifically as Figure 4 shown.

[0024] An inverted U-shaped shell is provided outside the drum. The heating device includes a heating mounting base 13 located below the drum. A clamping cavity for accommodating the hot air flow is formed by enclosing between the heating mounting base 13, the shell and the drum. The first air outlet pipe 21, the second air outlet pipe, and the third air outlet pipe are respectively connected and communicated with the clamping cavity through a first connecting air pipe 24, a second connecting air pipe 25, and a third connecting air pipe 26. A top fan 27 for blowing air into the clamping cavity is further provided on the shell. Specifically, the shell can be composed of a semi-circular upper shell 11 and side shells 12 extending downward from both sides of the upper shell 11, as Figure 3 shown, and the side shells 12 and the upper shell 11 are detachably assembled and connected. By utilizing the heat energy in the clamping cavity, more energy is saved. The hot air is used to assist in moisture removal, and the moisture removal effect is good and it will not have an adverse impact on the green tea fixing.

[0025] A further solution is as follows: The annular mounting plate 28 is fixedly mounted on the feeding end of the cylindrical shell. An observation window is provided on the annular mounting plate 28 for observing the feeding condition at the feeding end inside the drum. The observation window is provided on the annular mounting plate 28 between the second air outlet pipe and the third air outlet pipe. Since the discharge port of the feeding hopper is assembled at the vacant part in the middle of the mounting plate and the inside of the drum cannot be observed through the vacant part, the feeding condition at the feeding end of the drum can be conveniently understood through the setting of the observation window. At the same time, by setting the observation window at this position, when it is observed that there is tea accumulation at the feeding end, a blowing blower can be used. The air outlet of the blowing blower is assembled at the observation window to blow in air and push the tea for fixation treatment to ensure reliable processing of the tea. A latch plate 29 is provided at the observation window. The latch plate 29 is movably mounted along the radial direction of the annular mounting plate 28. The setting of the latch plate 29 allows it to be opened during observation and closed at other times to avoid heat dissipation. In addition, a temperature detection device 14 is provided in the middle of the side shell 12. The temperature sensor on the temperature detection device 14 extends into the clamping cavity for temperature measurement. The temperature detection devices 14 are arranged at intervals along the length direction of the drum. The temperature sensor is adjustably assembled in the horizontal direction perpendicular to the length direction of the drum. Selecting to assemble the temperature detection device 14 here, the detected temperature is the same as the temperature of the tea during fixation in the drum, and the detection accuracy is good. The temperature sensor is adjustably assembled to adapt to different situations for adjustment to ensure the reliability of temperature detection. Some ventilation holes can be provided on the annular mounting plate 28. The ventilation holes are arranged at intervals along the circumferential direction to improve the moisture discharge effect.

[0026] In summary, the above solution provided by the present utility model can effectively ensure the moisture discharge during tea fixation and improve the tea fixation effect.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special description and limitation.
