Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a tea rolling hot air fixing machine. Background Art

[0002] The main structure of the existing tea drum withering machine includes a frame, a control box, a horizontally arranged drum, a driving device, etc. One end of the drum is a feed port, and the other end is a discharge port; the driving device can drive the drum to rotate; the main structure of the drum is a sandwich structure, the sandwich structure is mainly hollow between the outer wall and the inner wall, the ends of the outer wall and the inner wall are connected by an end plate, an electric heating device is arranged inside the sandwich, which can heat the inner wall of the drum, and the sandwich structure has the function of maintaining temperature; a spiral tea guide plate is arranged on the inner wall of the drum. The working mode of the tea drum withering machine is: first preheat the drum through an electric heating device, that is, heat the inner wall of the drum to a moderate temperature, and then put the tea leaves to be withered from the feed port into the rotating drum. During the rotation of the drum, the tea leaves are constantly turned over and heated by the temperature of the inner wall of the drum to wither. During the process, the tea leaves will continue to move towards the discharge port under the guidance of the tea guide plate, and finally the tea leaves are discharged from the discharge port to complete the tea withering process.

[0003] However, the above-mentioned tea drum withering machine has some problems in actual use. According to the analysis of technicians, since the drum is relatively sealed and there is almost no air flow inside, the water evaporated from the tea leaves cannot be effectively discharged as the tea leaves are withered. When the humidity in the drum reaches a certain level, the adhesion of the tea leaves will increase, and some of the tea leaves in the drum will easily accumulate into small clumps, resulting in uneven withering of the tea leaves, affecting product quality. In addition, since the internal tea withering environment is relatively "stuffy", the tea leaves that come out of the withering process are not green enough and are slightly yellow.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] Embodiment 1, a tea drum hot air fixing machine.

[0027] In order to solve the problem that the water evaporated from the tea leaves inside the tea drum withering machine cannot be discharged in time and effectively, the technicians considered the technical means of ventilating the drum. With the action of wind, the moisture in the drum can be blown out. Because blowing cold air will cause the heat of the tea leaves that have been heated by the inner wall of the drum to be lost, affecting the withering effect, so the hot air withering method was thought of. It is proposed to use the high temperature that already exists in the hollow interlayer of the drum to heat the gas and introduce it into the drum to form gas circulation. In this way, hot air withering is combined with drum withering to achieve a better withering effect. For this reason, a design is designed. Figure 2 The drum hot air fixing machine of the structure is compared with the present embodiment, and the spherical wind direction diffuser 8 is not provided in the implementation structure. After implementation, Figure 2The effect of the drum hot air fixing machine with the structure is not good, because the hot air blown out is too concentrated, the wind speed is relatively fast, and the hot air blows directly to the discharge port, so the effect of this hot air assisted fixing is extremely limited, and under the action of the drum tea guide plate, when the tea leaves fall from a high place, the hot air will also blow the tea leaves forward for a distance during the falling process, which greatly reduces the time for the drum to fix the tea leaves, but will reduce the overall fixing effect. For this reason, the tea drum hot air fixing machine is further modified to obtain the present implementation structure.

[0028] The structure of this implementation refers to Figure 3-4 , including a drum 1 which is arranged horizontally and has a hollow sandwich structure; including a blower 2 connected to the hollow sandwich in the middle of the drum 1 and an air outlet pipe 3 connected to the hollow sandwich at the end of the feed port of the drum 1, the air outlet pipe 3 is connected to the pipe fitting 4, the pipe fitting 4 is connected to the ventilation pipe 5, the ventilation pipe 5 is connected to the elbow 6, the elbow 6 is connected to the air inlet pipe 7, the air inlet pipe 7 is connected to a spherical wind direction diffuser 8 arranged at the feed port of the drum 1, and a plurality of ventilation holes 9 are arranged on the spherical wind direction diffuser 8.

[0029] The spherical wind direction diffuser 8 is arranged at the center of the feed port to ensure that the hot air acts evenly on the tea leaves in various places in the drum as much as possible, thereby ensuring the consistency of the quality of the tea leaves after withering.

[0030] The pipe fitting 4 and the elbow 6 are both 90° elbows. This structure is simple and the transformation cost is low.

[0031] The air outlet pipe 3 and the pipe fitting 4, the pipe fitting 4 and the ventilation pipe 5, the ventilation pipe 5 and the elbow 6, the elbow 6 and the air inlet pipe 7, and the air inlet pipe 7 and the spherical wind direction diffuser 8 are all connected by threads. The threaded connection method is simple and easy to maintain.

[0032] The use of the tea drum hot air fixing machine is carried out on the existing drum fixing machine. The inner wall of the drum is first heated to the fixing temperature, and then tea leaves are put in and the drum fixing is carried out normally. During the process, the blower 2 is started, and the blower 2 ventilates the hollow interlayer of the drum 1. The temperature in the hollow interlayer and the electric heating device play a role in heating the air. The hot air is blown out from the air outlet pipe 3, and passes through the pipe fitting 4, the ventilation pipe 5, the elbow 6, the air inlet pipe 7 and the spherical wind direction diffuser 8 in sequence, and then blown out from each ventilation hole 9. The ventilation hole 9 is covered with the spherical wind direction diffuser 8 and faces the tea leaves at various positions in the front of the drum 1. The hot air in the air inlet pipe 7 passes through the spherical wind direction diffuser 8 to form a divergent wind flow, which effectively avoids the problem of wind flow concentration, and can carry out hot air fixing on the tea leaves that are being drum fixed in the drum 1. The hot air blown into various parts of the drum 1 will also move toward the discharge port as a whole, and will be discharged from the discharge port with the water vapor evaporated from the tea leaves during the process.

[0033] Embodiment 2, a tea drum hot air fixing machine.

[0034] Since the heat source for forming hot air in Example 1 is the electric heating device in the drum 1, hot air can only be used after the temperature in the drum 1 rises, and the temperature of the hot air is not easy to control, and it is impossible to adjust and maintain the hot air temperature at the optimal hot air fixing temperature. For this reason, the technicians further considered modifying the tea drum hot air fixing machine of Example 1, and proposed adding a temperature-adjustable hot air blower 10 next to the fixing machine, referring to Figure 6 As shown, however, in this solution, the hot air blower next to the fixing machine occupies more processing space, and the original pipe fittings 4, ventilation pipes 5, etc. are not utilized. Therefore, it is necessary to redesign and transform a more practical implementation structure.

[0035] This implementation structure is carried out on the basis of Example 1, and further, the pipe fitting is replaced by a tee, the tee is connected to the hot air duct 17, the hot air duct 17 is connected to the hot air blower 10, and the hot air blower 10 is arranged on the mounting seat 11, and the mounting seat 11 is arranged on the top of the drum 1.

[0036] The mounting seat 11 comprises a seat body 12, a mounting groove 13 is provided on the top of the seat body 12, and an arc groove 14 matching the outer wall of the drum 1 is provided on the bottom. The mounting groove 13 is used to place the hot air blower 10.

[0037] The left and right sides of the seat body 12 are provided with brackets 15, respectively. The brackets 15 play the role of anti-slip support.

[0038] There are two brackets 15 on the left and right sides respectively, and the bottom ends of the brackets 15 are set as arc-shaped end surfaces matching the outer wall of the drum 1.

[0039] The air outlet pipe 3 is provided with a valve 16. By opening and closing the valve 16, the heat of the drum 1 can be used to generate hot air and the hot air blower 10 can be used synchronously or only the hot air blower 10 can be used to generate hot air. The staff can flexibly operate according to the processing needs.

[0040] The hot air drying machine for tea leaves in a drum arranges the hot air blower 10 on the top of the tea drying machine through the mounting seat 11, which does not occupy any additional processing space. Furthermore, through the structure of the bracket 15 and the seat body 12, the modification can be completed by simply placing the seat body 12 on the drum 1 and then placing the hot air blower 10 in the mounting groove 13. The modification is quick and low-cost, and is easy to load and unload and maintain.

[0041] The existing drum tea-killing machine uses a heated drum to kill tea leaves. Due to the large heat capacity of the drum, it responds slowly to temperature changes, so it is still relatively slow to start killing tea leaves in a timely manner. After adding a hot air blower 10 in this embodiment, the hot air (which can block the discharge port) cooperates with the electric heating device in the drum to speed up the temperature increase efficiency in the drum and quickly enter the processable state; during use, the double killing of hot air + drum can speed up the killing efficiency, and the hot air can be properly adjusted to significantly improve the killing effect; it can also complete other processing operations such as rotating the drum but not heating it, and drying the tea leaves in the drum by hot air.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
