Description

Technical Field

[0001] The utility model relates to the field of white tea processing equipment, in particular to a withering device for tea processing. Background Art

[0002] The withering of white tea is the most core link in its production process, which determines the unique color, fragrance, taste and shape characteristics of white tea. The traditional withering form is mainly natural withering, emphasizing the maximum retention of the natural flavor of tea. After the fresh tea leaves are picked, they are usually spread thinly on bamboo plaques, withering racks or withering curtains, and placed in a ventilated, rainproof, sunny but not too strong place for drying. However, due to the bad outdoor weather, bad environment or too long withering time, withering machines are also used for auxiliary withering. For example, there is a tea withering machine disclosed in CN207269775U in the prior art, which includes a temperature-controlled withering chamber, and the temperature-controlled withering chamber includes a feed port arranged at the upper part and a discharge port at the lower part. After the tea leaves are discharged from the discharge port, they are conveyed to the feed port again by a conveying device for cyclic withering. The withering temperature is pre-set in the temperature-controlled withering chamber, and the tea leaves are placed from the feed port. After the withering is completed from top to bottom, they are discharged from the discharge port. This solution is similar to most of the existing technologies that use conveyor belts for differential layer transmission, and uses the different transmission directions of each layer of conveyor belts to achieve walking withering. However, this solution requires the installation of multiple conveyor belts and multiple power sources. Moreover, if the withering is not in place after one movement, it is necessary to consider sending the lower layer of white tea back to the first layer for withering again. The lifting device is not easy to set in the warehouse body, and it is also difficult to set outside. Therefore, it may still be necessary to manually send the white tea from a low position to a high position, which is not convenient for the continuous withering of the white tea.

[0003] Therefore, the utility model proposes a withering device for tea processing, so as to achieve the problem of continuous withering. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a withering device for tea processing.

[0005] The solution of the utility model provides a withering device for tea processing, comprising:

[0006] A withering room, a pushing assembly used inside the withering room, and a rotating assembly used to assist the white tea in rotating at a uniform speed in the withering room;

[0007] The interior of the withering room is divided into a withering chamber, a liquid accumulation chamber and an isolation chamber. A material receiving tray is provided at the bottom of the withering chamber. The material receiving tray is driven to rotate slowly by a motor in a rotating assembly. A plurality of evenly distributed water permeable holes are provided on the material receiving tray. A plurality of circumferentially distributed material pushing assemblies are provided above the material receiving tray. The material pushing assemblies include a cylinder provided outside the withering room, a moving rod is connected inwardly to the cylinder, and a push plate is fixedly installed at one end of the moving rod facing inward.

[0008] A blast pipe is provided on the top of the withering room, which blows air inwards. A liquid outlet pipe is provided at the bottom of the withering room, which is installed at the lowest point of the liquid accumulation chamber. The liquid accumulation chamber and the isolation chamber are separated by a liquid partition plate. Waterproof heating lamps are distributed inside the liquid accumulation chamber, and the irradiation light of the heating lamps is set upwards.

[0009] Furthermore, the push plate is a push plate with an inwardly curved arc, and each push plate is set with an equal arc length; when in a non-assembled state, the push plate is set on the periphery of the receiving tray, so as to avoid affecting the rotation of the internal white tea when not in use.

[0010] Furthermore, a rotating shaft is connected to an upward end of the motor, and the top of the rotating shaft is locked with the bottom of a receiving tray, and the receiving tray divides the withering room into a withering chamber and a liquid accumulation chamber.

[0011] Furthermore, the liquid isolation plate is arranged to be tilted downward, and a liquid outlet hole is provided at the lowest point of the liquid isolation plate. The liquid outlet hole is directly connected to the external liquid outlet pipe, and an electric control valve is installed on the liquid outlet pipe.

[0012] Furthermore, the liquid isolation plate divides the isolation cavity into a triangular structure, and the rotating shaft is arranged in the isolation cavity and is limited by the bearing, so that the rotating shaft can appear to be arranged vertically upward.

[0013] Furthermore, a circle of limiting nozzles is arranged on the outer circumference of the receiving plate, and the limiting nozzles are arranged in an arc-shaped outward curved hook shape; after assembly, the top of the limiting nozzles is close to but not in contact with the moving rod, which, on the one hand, does not affect the horizontal operation of the moving axis, and on the other hand, can effectively limit the white tea to prevent it from falling into the liquid accumulation cavity, thereby reducing the risk of withering again.

[0014] Furthermore, a temperature sensor and a humidity sensor are respectively provided on the side walls of the withering chamber, and the temperature sensor and the humidity sensor are respectively connected to the control end, so as to facilitate better real-time monitoring of the temperature and humidity in the withering chamber, better overall adjustment, and convenient use of the withering room.

[0015] Furthermore, the withering room is supported by pillars, and the liquid outlet pipe is arranged on the inner side of the pillars.

[0016] Furthermore, the heating lamp is a white light lamp.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the utility model separates the withering chamber into a withering chamber, a liquid accumulation chamber and an isolation chamber, so that each chamber can achieve the corresponding working purpose. The white tea withers in the withering chamber, wherein the heat brought upward by the heating lamp heats up the entire upper cavity, thereby increasing the temperature of the withering environment of the white tea. The hot air sent into the blast pipe evenly disperses the internal heat. At the same time, the temperature sensor and the humidity sensor synchronously monitor and control the heat energy of the heating lamp. Since a rotary fan is arranged at the bottom of the receiving tray, the temperature of the heating lamp is increased. The dynamic component drives the receiving tray to rotate slowly through the motor, so as to evenly distribute the heat to the white tea in all directions, realize the effect of continuous withering, and avoid the situation in the prior art that the tea is withered halfway and then transported and withered again. At the same time, a push plate is arranged on the periphery of the circumference of the receiving tray to solve the problem that the white tea in the middle moves to the edge due to centrifugal force and returns to the middle again under the action of the push plate. In this process, the distribution of the white tea can also be re-dispersed, so that the withering effect is more uniform and sufficient. A limit nozzle is arranged on the periphery of the receiving tray to effectively prevent the white tea from falling during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Specifically, Figure 1-Figure 4As shown, the embodiment of the utility model provides a withering device for tea processing, comprising:

[0029] A withering room 1 supported by a support 15, a pushing assembly 2 used inside the withering room 1 and a rotating assembly 3 used to assist the white tea in the withering room 1 to rotate at a uniform speed;

[0030] The withering room 1 is internally divided into a withering chamber 11, a liquid accumulation chamber 12 and an isolation chamber 13. A material receiving tray 33 is provided at the bottom of the withering chamber 11, wherein the withering chamber 11 and the liquid accumulation chamber 12 are mainly separated by the material receiving tray 33, because white tea is placed on the material receiving tray 33, and its main function is to achieve the withering effect of the white tea, and the white tea may partially dehydrate and drip during the withering process, so the bottom is separated into the liquid accumulation chamber 12, and in addition, the liquid accumulation chamber 12 and the isolation chamber 13 are separated by a liquid partition plate to prevent water vapor from indirectly affecting the service life of the internal rotating components, and the design and distribution are reasonable;

[0031] The receiving tray 33 is driven by the motor 31 in the rotating assembly 3 to rotate slowly, wherein the purpose of the slow rotation is to prevent the white tea from being thrown out during the rotation process.

[0032] Specifically, the upward end of the motor is connected to a rotating shaft, and the top of the rotating shaft is locked with the bottom of the receiving tray. In addition, it can effectively sense the heat from below and the heat from above. In order to prevent excessive withering of white tea, we also set a temperature sensor and a humidity sensor in the withering room 1. The temperature sensor and the humidity sensor are respectively connected to the control end, and the control end monitors in real time, so as to effectively adjust the temperature of the heating lamp 4 set at the bottom. The heating lamp 4 is a waterproof heating lamp 4, and the irradiation light of the heating lamp 4 is set upward;

[0033] The material receiving tray 33 is provided with a plurality of evenly distributed water-permeable holes, through which excess water vapor can be conveniently discharged. It should be noted that there is not much water vapor here, so the heating lamp 4 only needs to be waterproof and does not affect its functional use. A plurality of circumferentially distributed pushing components 2 are provided above the material receiving tray 33. The function of the pushing component 2 is mainly to push the pushing plate 23 inwardly through the cylinder 21, so that the tea leaves at the edge are pushed back into the middle after a period of time, so as to achieve the effect of re-breaking and fully withering and heating. Therefore, the pushing component 2 includes a cylinder 21 arranged outside the withering room 1, and the cylinder 21 is connected inwardly with a moving rod 22, and the pushing plate 23 is fixedly installed at the inward end of the moving rod 22. Of course, in order to effectively match the shape of the material receiving tray 33, the pushing plate 23 is also specially shaped, and the pushing plate is a pushing plate with an inward bending arc. Figure 2, each of the push plates is set with equal arc length; in the non-assembled state, the push plates are arranged on the periphery of the receiving tray, that is, when not in use, there is no effect on the automatic rotation of the internal white tea. It should be noted that the external shape formed by the plurality of push plates 23 as a whole is larger than the shape of the receiving tray 33;

[0034] In order to facilitate the equal distribution of heat in the withering room 1, a blast pipe 14 is provided on the top of the withering room 1, and the blast pipe 14 blows air inwardly. In order to facilitate the collection of the liquid after withering, a liquid outlet pipe 16 is provided at the bottom of the withering room 1, wherein the liquid outlet pipe 16 is arranged on the inner side of the support 15, and the liquid outlet pipe 16 is installed at the lowest point of the liquid accumulation chamber 12. The liquid accumulation chamber 12 and the isolation chamber 13 are separated by a liquid partition plate, and the liquid partition plate is arranged downwardly. The lowest point of the liquid partition plate is provided with a liquid outlet hole, and the liquid outlet hole is directly connected to the external liquid outlet pipe, and an electric control valve is installed on the liquid outlet pipe;

[0035] See Figure 2-4 In order to reduce the white tea from falling outwards during the continuous withering process, a circle of limiting nozzles is arranged on the outer circumference of the receiving tray. The limiting nozzles are arranged in an arc-shaped hook shape facing outwards. At the same time, in order to reduce the interference of the limiting nozzle with the moving rod, the top of the limiting nozzle is close to but not in contact with the moving rod, and a safety distance is provided.

[0036] When the utility model is in use, the door of the room is opened (not shown in the figure), the white tea to be withered is placed on the receiving tray, and then the white tea is spread out, the door of the withering room is closed, and then the heating lamp is turned on. It should be noted that the heating lamp mentioned here is a white light lamp and is not a common heating lamp source in the prior art. Then the motor is turned on, and the receiving tray is driven by the motor to rotate slowly, thereby driving the white tea to rotate slowly. During the rotation, the pushing component is not operated, and the blower is turned on synchronously. Hot air is slowly introduced through the blower. The control personnel observes the temperature and humidity in the withering room at the control end, so as to regulate the heat released by the heating lamp; after withering for a period of time, the rotating component is stopped, the pushing component is turned on, and the cylinder in the pushing component drives the moving rod to move inward, so that the push plate pushes the edge white tea inward, thereby rearranging the white tea to achieve sufficient withering and continuous withering.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
