Description
Technical Field
[0001] This utility model relates to the field of processing equipment technology, and in particular to a continuous processing equipment for steamed green tea with adjustable temperature. Background Technology
[0002] Steaming is a crucial step in green tea processing. Its main function is to use high-temperature steam to deactivate the enzymes in the tea leaves, thus stopping the fermentation process and preserving the unique color, aroma, and flavor of green tea. In the industrial production of steamed green tea, continuous processing equipment has become the mainstream equipment because it enables continuous feeding, steaming, and discharging of tea leaves, significantly improving production efficiency.
[0003] However, most equipment uses fixed steam generators and steam jet structures, with steaming temperatures typically set to a fixed value. This makes it difficult to adjust the temperature flexibly and precisely according to different varieties of tea leaves, varying degrees of freshness, and actual processing needs. In actual production, this lack of temperature adjustment easily leads to excessively high temperatures during steaming. Excessive temperatures can severely damage the tea's internal substances, such as tea polyphenols and amino acids. These substances are crucial components for the taste and nutritional value of green tea; excessive loss results in a weak flavor, insufficient aftertaste, and reduced nutritional value. High temperatures also damage chlorophyll and other pigments, causing the tea to become dull and lose its characteristic bright green luster, affecting its appearance. Furthermore, excessively high temperatures can cause scorching and burning of the tea leaves, producing unpleasant flavors and further reducing its commercial value. Therefore, this invention proposes a continuous steaming green tea processing device with adjustable temperature. Utility Model Content
[0004] The purpose of this invention is to address the problem in the prior art that existing continuous processing equipment for steamed green tea often has a fixed steaming temperature that is difficult to adjust flexibly and accurately, leading to the destruction of the tea's internal substances and pigments, as well as scorching and burning of the tea leaves, thus reducing the quality and commercial value of the tea.

[0009] Optionally, the steaming assembly includes a synchronization cylinder fixedly connected to the bottom of the material plate. The synchronization cylinder has air inlet pipes connected to its interior on both sides. The end of the air inlet pipe away from the synchronization cylinder is connected to a first flexible hose, and the end of the first flexible hose away from the air inlet pipe is connected to a steam source.
[0010] Optionally, two sets of vertically arranged mounting plates are fixedly connected to the inner wall of the synchronization cylinder. The mounting plates are L-shaped, and fan blades are respectively installed on the top of the two sets of mounting plates.
[0011] Optionally, a guide plate is fixedly connected to the bottom of the synchronization cylinder. The guide plate is inclined and located below the air inlet pipe.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example like Figure 1 As shown, the adjustable temperature continuous processing equipment for steamed green tea proposed in this utility model includes a base plate 1 and two sets of support frames 2 mounted on the base plate 1. The positions of the base plate 1 and the support frames 2 are fixed. Two sets of flexible vibration motors 3 are respectively installed on the top of the two sets of support frames 2.
[0024] Furthermore, the aforementioned processing equipment also includes a material plate 4 mounted on top of four sets of flexible vibration motors 3. The four sets of flexible vibration motors 3 are located at the four corners of the material plate 4. The four sets of flexible vibration motors 3 drive the material plate 4 to vibrate, and simultaneously move the tea leaves along the material plate 4. This utilizes the same existing technology as the flexible vibrating disc, which will not be elaborated upon here. Multiple sets of through holes 41 are provided on the material plate 4, allowing steam to pass through and contact the tea leaves. Two sets of baffles 42 are also fixedly connected to the top of the material plate 4, located on either side of the through holes 41. The baffles 42 prevent tea leaves from falling off the sides of the material plate 4.
[0025] For further details, please refer to Figure 1 and Figure 3The aforementioned processing equipment also includes a limiting mechanism 5 mounted on the material plate 4. The limiting mechanism 5 is used to confine the tea leaves to the position of the through hole 41 for steaming. The limiting mechanism 5 includes two sets of push rod motors 51 installed at the bottom of the material plate 4. The two sets of push rod motors 51 are located on opposite sides of the two sets of baffles 42. The output ends of the two sets of push rod motors 51 pass through the material plate 4 and are respectively fixedly connected to a top plate 52. After starting, the push rod motors 51 drive the top plates 52 to move up and down. Two sets of partitions 53 are fixedly connected between the two sets of top plates 52. When the top plates 52 move, they drive the partitions 53 to move synchronously. The partitions 53 are located between the two sets of baffles 42. The two sets of partitions 53, together with the two sets of baffles 42, surround the through hole 41, allowing the tea leaves to remain at the position of the through hole 41, facilitating contact between the steam and the tea leaves for steaming. Simultaneously, the vibration of the flexible vibration motor 3 turns the tea leaves over. After steaming, the partition 53 moves upward, and the tea leaves are moved to one side by the vibration of the flexible vibration motor 3. The tea leaves on the other side enter the through hole 41, realizing continuous processing. Multiple sets of limiting cylinders 54 are fixedly connected to the bottom of the two sets of top plates 52. Limiting rods 55 are slidably connected in the limiting cylinders 54. The limiting rods 55 are fixedly connected to the top of the material plate 4. Through the limiting action of the limiting cylinders 54 and the limiting rods 55, the movement of the top plates 52 is stable, thereby ensuring the smooth movement of the two sets of partitions 53.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the above-mentioned processing equipment includes a steaming assembly 6 located below the material plate 4, which is used to steam the tea leaves. The steaming assembly 6 includes a synchronization cylinder 61 fixedly connected to the bottom of the material plate 4. Air inlet pipes 62, communicating with the interior of the synchronization cylinder 61, are connected to both sides of the synchronization cylinder 61. A first flexible hose 63 is connected to the end of the air inlet pipe 62 away from the synchronization cylinder 61, and a steam source is connected to the end of the first flexible hose 63 away from the air inlet pipe 62. Steam provided by the steam source enters the synchronization cylinder 61 through the first flexible hose 63 and the air inlet pipe 62, and the steam contacts the tea leaves through the through hole 41. Two sets of vertically arranged mounting plates 64 are fixedly connected to the inner wall of the synchronization cylinder 61. The mounting plates 64 are L-shaped, and fan blades 65 are respectively installed on the top of the two sets of mounting plates 64. The fan blades 65 rotate when the steam passes through, thereby mixing the steam and avoiding uneven steam temperature. A guide plate 66 is fixedly connected to the bottom of the synchronization cylinder 61. The guide plate 66 is inclined and located below the air inlet pipe 62. A liquid outlet pipe 67 is connected to the side of the synchronization cylinder 61. The liquid outlet pipe 67 is located on the inclined side of the guide plate 66, so that the condensate flows to the side of the guide plate 66 and is discharged through the liquid outlet pipe 67.
[0027] Furthermore, the aforementioned processing equipment also includes a temperature control mechanism 7 installed in the steaming assembly 6, which is used to regulate the steam temperature. The temperature control mechanism 7 includes a condenser pipe 71 installed in the base plate 1. The condenser pipe 71 is inclined to facilitate the condensate that encounters the condenser pipe 71 to slide to one side. The inlet and outlet ends of the condenser pipe 71 both pass through and are fixedly connected to the synchronization cylinder 61. The inlet and outlet ends of the condenser pipe 71 are respectively connected to an inlet hose 72 and an outlet hose 75. The end of the inlet hose 72 away from the condenser pipe 71 is connected to a T-shaped pipe 73, and the end of the T-shaped pipe 73 is connected to a second hose 74. The second hose 74 and the outlet hose 75 are connected to the cooling water circulation system to facilitate the flow of circulating water in the condenser pipe 71 and reduce the temperature when the steam passes through the condenser pipe 71. One end of the T-shaped pipe 73 is connected to a third flexible hose 77, which is connected to a water pump. The water pump is connected to a hot water source, and the water pump delivers hot water through the T-shaped pipe 73 and the inlet hose 72 into the condenser pipe 71. At the same time, cold water from the cooling water circulation system enters the condenser pipe 71 through the second flexible hose 74, the T-shaped pipe 73, and the inlet hose 72. The cold water and hot water mix at the T-shaped pipe 73, thereby increasing the temperature of the condenser pipe 71 and adjusting the range of steam temperature regulation. A solenoid valve 76 is installed at the connection section between the T-shaped pipe 73 and the third flexible hose 77 to adjust the inflow of hot water, thereby regulating the temperature of the condenser pipe 71.
[0028] Multiple temperature sensors 8 are installed on the side of the synchronization cylinder 61, located above the fan blades 65. These sensors detect the temperature of the steam in contact with the tea leaves. A control box 9 is also installed on the top of the base plate 1. The flexible vibration motor 3, push rod motor 51, solenoid valve 76, and temperature sensors 8 are all electrically connected to the control box 9. The control box 9 controls the two sets of push rod motors 51 to work synchronously, ensuring that the two sets of top plates 52 move synchronously and preventing the two sets of partitions 53 from tilting. The control box 9 controls the opening and closing of the solenoid valve 76, thereby adjusting the temperature of the condenser pipe 71 and thus the steam temperature.
[0029] In this embodiment, firstly, when the flexible vibration motor 3 operates, it drives the material plate 4 to vibrate. Utilizing the same existing technology principle as the flexible vibrating disc, the tea leaves on the material plate 4 move towards the through hole 41 area along the vibration direction. The baffles 42 on both sides of the material plate 4 prevent the tea leaves from falling off during the movement. When the tea leaves move to the position of the through hole 41 on the material plate 4, the control box 9 controls the two sets of push rod motors 51 at the bottom of the material plate 4 to start. The output ends of the push rod motors 51 push the top plate 52 downward. At this time, the multiple sets of limiting cylinders 54 at the bottom of the top plate 52 slide along the limiting rods 55 to ensure that the top plate 52 moves smoothly, thereby driving the two sets of partitions 53 to move downward synchronously. The two sets of partitions 53 and the two sets of baffles 42 cooperate to surround the through hole 41, confining the tea leaves in the area directly above the through hole 41. At the same time, the flexible vibration motor 3 continues to vibrate, which can cause the tea leaves in the confined area to turn slightly, ensuring that the tea leaves are heated evenly.
[0030] Steam generated by the steam source then enters the synchronization cylinder 61, fixed to the bottom of the material plate 4, through the first hose 63 and the air inlet pipe 62. As the steam rises within the synchronization cylinder 61, it flows over the fan blades 65 on top of the two sets of L-shaped mounting plates 64. The steam flow drives the fan blades 65 to rotate, stirring and mixing the steam to prevent uneven local temperature from affecting the steaming effect. The mixed steam then passes through the through-holes 41 on the material plate 4 and fully contacts the tea leaves within the defined area above, achieving the steaming process. The condensate generated during steaming falls onto the inclined guide plate 66 at the bottom of the synchronization cylinder 61, flows along the inclined direction of the guide plate 66 to the liquid outlet pipe 67, and is discharged outside the synchronization cylinder 61 through the liquid outlet pipe 67. Multiple temperature sensors 8 monitor the temperature of the steam in contact with the tea leaves in real time and transmit the temperature data to the control box 9. When control box 9 detects that the steam temperature is higher than the preset target temperature, control box 9 controls the solenoid valve 76 on the connection section between T-tube 73 and third hose 77 to reduce its opening degree, thereby reducing the hot water inflow from the hot water source. Simultaneously, the cooling water circulation system delivers cold water to T-tube 73 through second hose 74. The cold water mixes with a small amount of hot water within T-tube 73 and then flows into the inclined condenser pipe 71 through inlet hose 72. The low-temperature mixed water in condenser pipe 71 exchanges heat with the rising steam in synchronous cylinder 61, lowering the steam temperature until temperature sensor 8 detects that the steam temperature has reached the preset value. Control box 9 then adjusts solenoid valve 76 to maintain its current opening degree, stabilizing the steam temperature within the target range. If the steam temperature is lower than the preset value, control box 9 increases the opening degree of solenoid valve 76, increasing the hot water inflow, raising the temperature of the mixed water in condenser pipe 71, and reducing the cooling effect on the steam, thus achieving precise temperature control.
[0031] After the tea leaves have completed steaming in the through-hole 41 area, the control box 9 controls the push rod motor 51 to drive the top plate 52 and partition 53 to reset upwards, releasing the restriction on the tea leaves. At this time, the vibration of the flexible vibration motor 3 continues to drive the steamed tea leaves to move towards the material plate 4 and discharge them. Meanwhile, the tea leaves to be steamed later enter the through-hole 41 area under the action of vibration, repeating the above-mentioned restriction, steaming and temperature control process, thereby realizing the continuous steaming and processing of tea leaves.
[0032] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
