Description
Technical Field
[0001] The invention relates to the technical field of tea production, and in particular to integrated tea withering and cooling equipment and an energy-saving control process. Background Art
[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the Camellia sinensis plant; The production process of tea includes tea leaf killing, which refers to the destruction of oxidase activity in fresh leaves by high temperature, inhibiting the oxidation of polyphenols and releasing a grassy flavor. It is a key step in shaping the quality of tea. In the traditional tea processing field, there are various types of tea-fixing equipment, among which the more common ones include drum tea-fixing machines and microwave tea-fixing machines. These tea-fixing equipment play a vital role in the tea processing process. They use specific working principles and operating methods to fix the tea leaves, so that the tea leaves can maintain their due quality and flavor. After completing this key process of fixing the tea leaves, the tea leaves need to be quickly cooled. This is because if the tea leaves after fixing are not cooled in time, they will face the risk of excessive oxidation. Excessive oxidation will not only affect the taste of the tea, making it lose its original fresh taste, but also cause a large amount of tea aroma to be lost, which will seriously affect the quality of the tea. In actual operation, the two common methods of cooling tea leaves after withering are spreading and cooling with a fan. However, the two processes of withering and cooling are usually independent of each other.

DETAILED DESCRIPTION
[0017] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples. Example 1
[0018] See also Figures 1 to 8 The present invention provides a technical solution: an integrated tea leaf fixing and cooling equipment, comprising: A fixing and cooling box 1 is provided with a heat insulation board 20 inside the fixing and cooling box 1. The fixing and cooling box 1 is divided into a fixing chamber 21 and a cooling chamber 22 by the heat insulation board 20. The fixing chamber 21 is located above the cooling chamber 22. The drum 19 is rotatably disposed inside the killing chamber 21, and a hot air plate 27 is installed on the inner side wall of the killing chamber 21 at a position corresponding to the drum 19; The evaporator 23 is arranged at the bottom end of the cooling chamber 22, and the condenser 12 is installed on the outer wall of the fixing cooling box 1 at the position corresponding to the evaporator 23; A heat collection assembly is used to collect heat inside the fixing chamber 21. The heat collection assembly includes a second heat exchanger 37 disposed above the fixing chamber 21. A conveying assembly is disposed above the second heat exchanger 37 and is in communication with the drum 19. The hot air plate 27 is used to heat the tea leaves in the withering chamber 21. After the withering process, the tea leaves to be cooled are transported to the cooling chamber 22. The evaporator 23 is used to cool the tea leaves after withering. The condenser 12 is provided to cooperate with the evaporator 23 to continuously cool the interior of the cooling chamber 22. When the hot air plate 27 performs high-temperature withering in the withering chamber 21, the heat collecting component can collect the high temperature brought out by the withering exhaust gas in the withering chamber 21, and preheat the tea leaves on the conveying component, thereby shortening the heating time of the tea leaves. Example 2

The inner wall of the drum 19 is provided with a first spiral guide plate 32 and a second spiral guide plate 33. The pitch of the first spiral guide plate 32 is smaller than the pitch of the second spiral guide plate 33. The hot air plate 27 is located on one side of the first spiral guide plate 32. The cooperation of the first motor 3 and the support shaft 24 drives the drum 19 to rotate. When the drum 19 rotates, the hot air plate 27 performs high-temperature sterilization on the tea leaves inside the drum 19. At the same time, the tea leaves move toward the other end of the drum 19 with the cooperation of the first spiral guide plate 32 and the second spiral guide plate 33. The cooperation of the first spiral guide plate 32 and the second spiral guide plate 33 will prevent the tea leaves from piling up inside the drum 19. The pitch of the first spiral guide plate 32 is large, and the tea leaves are more dispersed, which can promote the diffusion of high temperature among the tea leaves. The pitch of the second spiral guide plate 33 is small, and it gradually moves away from the hot air plate 27, which can extend the residence time of the tea leaves inside the drum 19, make the tea leaves sterilized more fully, and there is no need to worry about the burnt edges of the hot air plate 27.

At a position on the side wall of one set of the brackets 6 corresponding to the position of the rotating shaft 25, a second motor 8 is installed, and the output end of the second motor 8 passes through the side wall of the bracket 6 and is connected to the corresponding rotating shaft 25; At a position below the end of the second conveyor belt 7 inside the preheating box 2, a feed pipe 17 is installed, and a feed hopper 16 is communicated and arranged above the feed pipe 17; At a position below the feed pipe 17 on the outer surface of the drum 19, an annular groove 34 is provided. There are two sets of the annular grooves 34, and the other set of the annular grooves 34 is provided at the other end of the drum 19; The outer surfaces of the two sets of the annular grooves 34 are both sleeved with collar rings 18.

At this time, the tea leaves inside the feed hopper 16 can be conveyed into the drum 19 through the collar ring 18 for tumbling and killing green treatment. Embodiment Four
[0021] As Figure 4 and Figure 8 shown, the integrated tea - killing and cooling integrated equipment and energy - saving control process disclosed in Embodiment Four of the present invention has basically the same structure as that in Embodiment Three, and the differences are as follows: At a position of the other end of the drum 19 corresponding to the collar ring 18, a discharge groove 36 is provided. The discharge groove 36 is communicated with the other set of the collar rings 18, and a discharge pipe 31 is installed at a position of the other set of the collar rings 18 corresponding to the discharge groove 36; One end of the discharge pipe 31 away from the collar ring 18 passes through the heat - insulating plate 20 and extends into the interior of the cooling chamber 22; On one side of the bottom of the discharge pipe 31, a fixing frame 44 is installed. An automatic telescopic rod 43 is installed on the fixing frame 44. A through - slot 42 is provided on the side wall of the discharge pipe 31 corresponding to the output end of the automatic telescopic rod 43. A partition plate 41 is slidably arranged inside the through - slot 42, and the side wall of the partition plate 41 is connected to the output end of the automatic telescopic rod 43; With the cooperation of the first spiral guide plate 32 and the second spiral guide plate 33, the tea leaves gradually move to the end of the drum 19. When the drum 19 rotates, the discharge chute 36 will coincide with the discharge pipe 31. At this time, the tea leaves fall into the discharge pipe 31 through the discharge chute 36 and are collected by the partition 41. The setting of the partition 41 can block the discharge pipe 31 to reduce the contact between high-temperature hot air and low-temperature cool air. After a certain period of time, the automatic telescopic rod 43 is started, and the automatic telescopic rod 43 drives the partition 41 to move out from the inside of the discharge pipe 31. At this time, the tea leaves after withering in the discharge pipe 31 can enter the cooling chamber 22 for cooling. Example 5
[0022] like Figure 3 As shown, the structure of the integrated tea leaf fixing and cooling equipment and energy-saving control process disclosed in the fourth embodiment of the present invention is basically the same as that in the third embodiment, except that: Rotating shafts 25 are rotatably provided at both ends of the cooling chamber 22, a first conveyor belt 5 is sleeved between the two sets of rotating shafts 25, and a second motor 8 is installed at the position of the outer wall of the fixing cooling box 1 corresponding to one set of the rotating shafts 25, and the output end of the second motor 8 passes through the side wall of the fixing cooling box 1 and is connected to the end of one set of the rotating shafts 25; The first conveyor belt 5 is rotatably arranged between the discharge pipe 31 and the evaporator 23 through the cooperation of the two sets of rotating shafts 25; The outer wall of the fixing and cooling box 1 is provided with a discharge port 4 corresponding to the end of the first conveyor belt 5, and one end of the first conveyor belt 5 extends to the outside of the fixing and cooling box 1 through the discharge port 4; The tea leaves entering the cooling chamber 22 will fall onto the surface of the first conveyor belt 5 for cooling.

After cooling, the tea leaves are discharged through the discharge port 4. Example 6
[0023] like Figure 3-Figure 4 As shown, the structure of the integrated tea leaf fixing and cooling integrated equipment and energy-saving control process disclosed in the sixth embodiment of the present invention is basically the same as that in the fifth embodiment, except that: A first heat exchanger 11 is installed on the side wall of the condenser 12. The output end of the first heat exchanger 11 is connected to a first connecting pipe 10. The other end of the first connecting pipe 10 is connected to an air pump 9. The outer surface of the drum 19 is provided with a spiral tube 26 at a position corresponding to the second spiral guide plate 33, and the outer surface of the spiral tube 26 is provided with blowing holes 28 distributed at intervals; A third connecting tube 30 is provided between the end of the spiral tube 26 and the output end of the air pump 9, and the spiral tube 26 is connected to the air pump 9 through the third connecting tube 30; The evaporator 23 can cool the tea leaves after withering, and the setting of the condenser 12, when cooling the evaporator 23, its own heat will also be absorbed by the first heat exchanger 11, and then heat the gas extracted by the air pump 9, and discharge the heated gas to the tea leaves inside the drum 19 through the spiral tube 26, thereby heating the tea leaves inside the drum 19 and reducing the power consumption of the hot air plate 27. Example 7
[0024] like Figure 6-Figure 7 As shown, the structure of the integrated tea leaf fixing and cooling equipment and energy-saving control process disclosed in the seventh embodiment of the present invention is basically the same as that in the sixth embodiment, except that: A heat exchange groove 38 is provided between the fixing cooling box 1 and the preheating box 2, and the fixing cooling box 1 is connected to the preheating box 2 through the heat exchange groove 38; A negative pressure suction device 39 is provided inside the heat exchange tank 38, and a second heat exchanger 37 is provided above the negative pressure suction device 39; A U-shaped heat dissipation pipe 15 is provided inside the second conveyor belt 7. A second connecting pipe 14 and a fourth connecting pipe 40 are provided between the two ends of the U-shaped heat dissipation pipe 15 and the two ends of the second heat exchanger 37, respectively. The tea leaves are transported to the inside of the drum 19 through the cooperation of the second conveyor belt 7, the feed hopper 16 and the feed pipe 17, and are subjected to high-temperature withering treatment by the hot air plate 27. During the high-temperature withering process, the tea leaves are discharged to the second heat exchanger 37 through the negative pressure suction device 39, and heat transfer is achieved through the second heat exchanger 37 to heat the water flow inside the U-shaped heat dissipation tube 15. The water inside the U-shaped heat dissipation tube 15 is heated, thereby preheating the tea leaves on the second conveyor belt 7.
[0025] Energy-saving control processes include: Tea leaf withering: The tea leaves are transported to the inside of the drum 19, and then the hot air plate 27 heats the inside of the withering chamber 21 to achieve the withering of the tea leaves; Preheating of tea leaves: When the tea leaves are being withered, the exhaust gas from the withering chamber 21 is discharged to the second heat exchanger 37 through the negative pressure suction device 39. The heat is transferred through the second heat exchanger 37 to heat the water flow inside the U-shaped heat pipe 15. The water inside the U-shaped heat pipe 15 is heated, thereby preheating the tea leaves on the second conveyor belt 7. Cooling of tea leaves: After the tea leaves are withered, the tea leaves are transported to the inside of the discharge pipe 31 through the cooperation of the first spiral guide plate 32 and the second spiral guide plate 33, and then discharged to the upper surface of the first conveyor belt 5 through the discharge pipe 31. At this time, the evaporator 23 can cool the tea leaves after withering.
[0026] This solution is specifically as follows: the second conveyor belt 7 is driven to rotate by the second motor 8 to transport the tea leaves to be withered into the feed hopper 16. When the drum 19 rotates, the feed groove 35 and the feed pipe 17 overlap. At this time, the tea leaves in the feed hopper 16 can be transported to the drum 19 through the sleeve 18. Then, the first motor 3 and the support shaft 24 cooperate to drive the drum 19 to rotate. When the drum 19 rotates, the hot air plate 27 withers the tea leaves in the drum 19 at high temperature. At the same time, the tea leaves move toward the other end of the drum 19 under the cooperation of the first spiral guide plate 32 and the second spiral guide plate 33. At the same time, the tea leaves are conveyed to the inside of the drum 19 through the cooperation of the second conveyor belt 7, the feed hopper 16 and the feed pipe 17, and are subjected to a high-temperature fixation treatment on the tea leaves by the hot air plate 27. During the high-temperature fixation process, the tea leaves are discharged to the second heat exchanger 37 through the negative pressure suction device 39. The heat is transferred through the second heat exchanger 37, heating the water flow inside the U-shaped heat pipe 15. The water inside the U-shaped heat pipe 15 is heated, thereby preheating the tea leaves on the second conveyor belt 7. When the drum 19 rotates, the discharge chute 36 will overlap with the discharge pipe 31. At this time, the tea leaves fall into the discharge pipe 31 through the discharge chute 36 and are collected by the partition 41. The setting of the partition 41 can block the discharge pipe 31 and prevent the fixing chamber 21 and the cooling chamber 22 from communicating through the discharge pipe 31. After a certain period of time, the automatic telescopic rod 43 is started, and the automatic telescopic rod 43 drives the partition 41 to move out from the inside of the discharge pipe 31. At this time, the tea leaves after withering in the discharge pipe 31 will fall onto the surface of the first conveyor belt 5 for cooling. When falling, the accumulation of tea leaves can be avoided by the rotation of the first conveyor belt 5, and the evaporator 23 in the cooling chamber 22 can cool the tea leaves after withering. The setting of the condenser 12, when cooling the evaporator 23, its own heat will also be absorbed by the first heat exchanger 11, and then the gas extracted by the air pump 9 is heated, and the heated gas is discharged to the tea leaves inside the drum 19 through the spiral tube 26, so as to heat the tea leaves inside the drum 19 and reduce the power consumption of the hot air plate 27.
