Description

Technical Field

[0001] This utility model relates to the field of tea processing and roasting technology, specifically a temperature-controlled tea processing and roasting machine. Background Technology

[0002] Temperature-controlled tea processing and roasting machines are used in the tea processing process, mainly for the drying and roasting stages of tea. By precisely controlling the temperature, this equipment can ensure that the tea obtains the best flavor, aroma, and color during processing. Its main purpose is to remove excess moisture from the tea, prevent the tea from deteriorating, extend its shelf life, and change or enhance the aroma, taste, and color of the tea through heat treatment, thereby improving the quality of the tea.

[0003] Common temperature-controlled tea processing and roasting machines often use the large amount of heat generated during the heating process only to directly heat the tea leaves to be roasted. Due to the lack of an effective heat reuse mechanism, a large amount of residual heat is wasted. Furthermore, some temperature-controlled tea processing and roasting machines are not designed with a preheating function. This means that each time a new batch of tea leaves enters the roasting chamber, it is necessary to gradually raise the temperature from room temperature. This not only increases energy consumption but also prolongs the overall roasting time. If the residual heat generated during the roasting process of the previous batch could be effectively utilized for preheating, the waste of excess heat could be avoided, and the energy required for subsequent heating could be reduced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temperature-controlled tea processing and roasting machine. Through a symmetrical layout of dual temperature-controlled chambers, when one chamber is roasting at high temperature, the excess heat generated is transported to the other chamber via an air exchange component for preheating the tea, reducing subsequent energy consumption. At the same time, the exhaust of hot air can be controlled to stabilize the temperature. This solves the problem that common temperature-controlled tea processing and roasting machines lack an effective heat reuse mechanism and cannot effectively utilize the residual heat generated during the previous batch of roasting for preheating.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a temperature-controlled tea processing and roasting machine, comprising a temperature control box, wherein two temperature control boxes are provided; and a ventilation box disposed between the two temperature control boxes, wherein a ventilation component is provided inside the ventilation box, and a sliding component is provided inside the temperature control box; The sliding assembly is equipped with a baking component. The sliding assembly is used to move the baking component outside the device. The ventilation assembly is used to transfer excess heat from the temperature control box that is baking to another temperature control box to preheat the tea. A heat recovery pipe is installed on the left side of the temperature control box. The heat recovery pipe is used to recover excess heat from the preheating temperature control box.

[0006] Furthermore, a hot gas supply pipe is connected to the rear end of the temperature control box. One end of the hot gas supply pipe extends into the temperature control box and is connected to a flow divider. Multiple nozzles are installed on the surface of the flow divider. The hot gas supply pipe is connected to the air inlet pipe of the external temperature controller. The nozzles are used to spray gas to control the temperature inside the temperature control box.

[0007] Furthermore, the sliding assembly includes two slide rails installed at the bottom of the temperature control box, a mounting plate slidably connected to the upper surface of the slide rails, two fixing plates fixed to the upper surface of the mounting plate, and a sealing door connected to the front side of the fixing plate. The mounting plate can slide along the slide rails and is used to support the movement of the upper structure.

[0008] Furthermore, the baking assembly includes a motor mounted on the right fixed plate, a mesh storage box mounted on the motor output end, and a door mounted on the top of the mesh storage box. The end of the mesh storage box away from the motor is rotatably connected to the left fixed plate. The motor is used to drive the mesh storage box to rotate, and the door can be opened to place the tea leaves to be baked.

[0009] Furthermore, two rows of air holes are respectively opened on the side of the two temperature control boxes near the ventilation box. The air holes are used to connect the gas channels of the two temperature control boxes and the ventilation components. When one temperature control box is baking, excess hot air can be transported to the other temperature control box through the air holes, which can preheat the tea in the other temperature control box.

[0010] Furthermore, the ventilation assembly includes a fixed pipe installed inside the ventilation box, a bidirectional pump installed on the outer side of the fixed pipe, sealed pipes installed at each row of air holes, a delivery pipe connected between a pair of sealed pipes, and an air supply pipe connected to the outer side of the delivery pipe, with the other end of the air supply pipe connected to the fixed pipe.

[0011] Furthermore, the bidirectional pump is used to transport excess hot air from the baking temperature control box to the fixed pipe in sequence through the air hole, sealed pipe, delivery pipe and gas supply pipe. The excess hot air then enters the preheating temperature control box in sequence through the gas supply pipe, delivery pipe, sealed pipe and air hole.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. When one temperature control chamber is in a high-temperature roasting state, a large amount of high-temperature gas is generated. Through the ventilation component, this excess heat gas is transported to another temperature control chamber for preheating and initial dehydration of the next batch of tea leaves, reducing the energy required for subsequent heating in the other temperature control chamber. By controlling the discharge of some high-temperature gas, the peak temperature inside the chamber can be reduced, making room for the circulating air delivered by the temperature controller, thereby improving the accuracy and stability of temperature control. 2. The dual temperature control chambers are arranged symmetrically. When one temperature control chamber is in the high-temperature roasting stage, the other temperature control chamber can simultaneously load, preheat, or unload the tea. After the first chamber finishes roasting, the functions of the two chambers are immediately switched. The original roasting chamber enters the cooling and loading / unloading state, while the original preheating chamber enters the formal roasting program. Through the coordinated scheduling of the ventilation components and intelligent control, the heat energy is automatically transferred from the working chamber to the standby chamber, realizing the pre-utilization of heat energy. The whole process does not require stopping the machine to wait. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 This embodiment of a temperature-controlled tea processing and roasting machine includes a temperature control box 1, and two temperature control boxes 1 are provided; it also includes a ventilation box 2 disposed between the two temperature control boxes 1, the ventilation box 2 is provided with a ventilation component, and the temperature control box 1 is provided with a sliding component.

[0017] In this embodiment, with the symmetrical layout of the dual temperature control chambers 1, when one chamber is roasting at high temperature, the excess heat generated is transported to the other chamber through the ventilation component for tea preheating, reducing subsequent energy consumption. At the same time, the heat can be controlled to discharge to stabilize the temperature. The other chamber can be loaded, unloaded or preheated simultaneously. After roasting is completed, the functions of the two chambers are switched immediately to achieve continuous operation without downtime and efficient utilization of heat energy.

[0018] Please see Figures 1-3 In this embodiment, in order to send the hot air generated by the temperature control box 1 during baking to another box to preheat the next batch of tea, a baking component is installed on the sliding component in this embodiment. The sliding component is used to move the baking component out of the device. The ventilation component is used to transfer the excess hot air in the temperature control box 1 during baking to another temperature control box 1 to preheat the tea. A heat recovery pipe 10 is installed on the left side of the temperature control box 1. The heat recovery pipe 10 is used to recover the excess hot air in the preheated temperature control box 1.

[0019] In this embodiment, the sliding assembly is used to move the entire roasting assembly outside the equipment for easy loading and unloading of tea leaves and cleaning and maintenance. The roasting assembly is used to hold the tea leaves and rotate them for roasting to ensure even heating. The ventilation assembly is used to transport excess hot air from the temperature control box 1 that is roasting to another temperature control box 1 to preheat the next batch of tea leaves and achieve heat energy reuse. The hot air recovery pipe 10 is installed on the left side of the temperature control box 1 to recover excess heat during the preheating process to prevent the temperature from getting too high and to improve energy utilization efficiency. The two temperature control boxes 1 work alternately. When one is roasting, the other is preheating or the loading and unloading is completed, and then the switch is made to achieve continuous production. The hot air is directionally transmitted through the ventilation assembly to reduce energy waste and improve temperature control stability. The entire structure achieves the purpose of waste heat utilization, convenient operation, and high production efficiency.

[0020] It should be noted that the bidirectional pump 16 is used to transport excess hot air from the baking temperature control box 1 sequentially through the air hole 11, the sealed pipe 12, the conveying pipe 13, and the air supply pipe 14 to the fixed pipe 15. The excess hot air then enters the preheating temperature control box 1 sequentially through the air supply pipe 14, the conveying pipe 13, the sealed pipe 12, and the air hole 11. The bidirectional pump 16 can automatically switch the airflow direction under intelligent control and coordination with the temperature and humidity sensors according to the real-time working status of the two temperature control boxes 1, and determine which box is currently in the baking stage (as the heat source output end) and which box is in the preheating preparation stage (as the heat receiving end), thereby realizing directional heat energy transfer with active heat dissipation from the baking box and efficient heat absorption from the preheating box, ensuring the optimal heat energy utilization path.

[0021] Please see Figures 1-3In this embodiment, to enable the two boxes to work alternately, one for baking and the other for storing tea or preparing it, the sliding assembly in this embodiment includes two slide rails 3 installed at the bottom of the temperature control box 1, a mounting plate 4 slidably connected to the upper surface of the slide rails 3, two fixing plates 5 fixed to the upper surface of the mounting plate 4, and a sealing door 9 connected to the front side of the fixing plate 5. The mounting plate 4 can slide along the slide rails 3 and is used to support the movement of the upper structure. The baking assembly includes a motor 6 installed on the right fixing plate 5, a mesh storage box 7 installed at the output end of the motor 6, and a box door 8 installed on the upper end of the mesh storage box 7. The end of the mesh storage box 7 away from the motor 6 is rotatably connected to the left fixing plate 5. The motor 6 is used to drive the mesh storage box 7 to rotate, and the box door 8 can be opened to place the tea to be baked.

[0022] In this embodiment, the slide rail 3 is used to support and guide the mounting plate 4 to slide smoothly. The mounting plate 4 is used to support the overall movement of the structure, including the fixing plate 5, the motor 6, and the mesh storage box 7. The fixing plate 5 is used to fix the rotating end of the motor 6 and support the mesh storage box 7. The sealing door 9 is used to close the front of the temperature control box 1 to maintain the internal environment during baking. The motor 6 is used to drive the mesh storage box 7 to rotate so that the tea is heated evenly. The mesh storage box 7 is used to store tea, and its mesh structure facilitates the circulation of hot air. The box door 8 is used to open the mesh storage box 7 to facilitate the insertion or removal of tea.

[0023] Please see Figures 1-5 It should be noted that a hot gas supply pipe 17 is connected to the rear end of the temperature control box 1. One end of the hot gas supply pipe 17 extending into the temperature control box 1 is connected to a diverter plate 18. Multiple nozzles 19 are mounted on the surface of the diverter plate 18. The hot gas supply pipe 17 is connected to the air inlet pipe of an external temperature controller. The nozzles 19 are used to spray gas to control the temperature inside the temperature control box 1. Two rows of air holes 11 are respectively opened on the side of each of the two temperature control boxes 1 near the ventilation box 2. The air holes 11 are used to connect the gas passages of the two temperature control boxes 1 and the ventilation assembly. When one... When the temperature control box 1 is baking, excess hot air can be transported to another temperature control box 1 through the air hole 11 to preheat the tea in the other temperature control box 1. The ventilation component includes a fixed pipe 15 set inside the ventilation box 2, a bidirectional pump 16 installed on the outer side of the fixed pipe 15, a sealed pipe 12 installed at each row of air holes 11, a conveying pipe 13 connected between a pair of sealed pipes 12, and an air supply pipe 14 connected to the outer side of the conveying pipe 13. The other end of the air supply pipe 14 is connected to the fixed pipe 15.

[0024] The working principle of the above embodiments is as follows: During use, before starting operation, one of the two temperature control chambers 1 is in standby mode, while the other is ready for high-temperature roasting. At this time, the bidirectional pump 16 is in the off state, and the air vent 11 and sealing pipe 12 system are also in the off or standby state. The operator pulls the mounting plate 4 out of the equipment by sliding out the assembly, opens the chamber door 8, loads the tea to be roasted into the mesh storage box 7, then closes the chamber door 8 and pushes the mounting plate 4 back to its original position. When one temperature control chamber 1 starts high-temperature roasting, the internal heating element starts working, generating a large amount of high-temperature moisture. The motor 6 drives the mesh storage box 7 to rotate slowly, so that the tea leaves are evenly turned over during the roasting process, ensuring uniform heating and avoiding local overheating or sticking. As the roasting progresses... As the temperature inside temperature control chamber 1 gradually increases, the humidity also increases. To maintain the optimal baking environment and prevent excessively high temperatures, some of the high-temperature, humid air is discharged through the ventilation system. The bidirectional pump 16 is activated, which transports excess hot air from temperature control chamber 1 to fixed pipe 15 through air vent 11, sealed pipe 12, conveying pipe 13, and air supply pipe 14. This hot air then enters another temperature control chamber 1 through the other side of the conveying path to preheat and initially dehydrate the tea leaves inside. The heat recovery pipe 10 is installed on the left side of temperature control chamber 1 to recover excess heat generated during the preheating process, prevent excessively high temperatures, and further improve energy efficiency. Temperature and humidity sensors monitor the temperature and humidity changes inside the two temperature control chambers 1 in real time. The intelligent control system automatically adjusts the working mode of the bidirectional pump 16 based on this data to ensure the correct and stable direction of hot air flow. When the temperature of the temperature control chamber 1 approaches the set upper limit, some high-temperature gas is discharged to reduce the temperature peak and maintain the stability of the temperature field. By precisely controlling the inlet and outlet air volume and the exhaust volume, the temperature and humidity in each temperature control chamber 1 are always kept within the ideal range, improving the accuracy and stability of temperature control. After the temperature control chamber 1 has finished baking, it immediately switches roles. This temperature control chamber 1 stops heating, the sliding assembly pulls out the mounting plate 4, and the operator opens the chamber door 8 to remove the baked gas. The tea leaves are removed and new tea leaves to be roasted are added. Then, the mounting plate 4 is pushed back into place. At the same time, another temperature control box 1 begins to roast. The bidirectional pump 16 synchronously switches the airflow direction, so that hot air is sent from the new temperature control box 1 to the new temperature control box 1. This achieves a seamless connection between the two boxes, eliminating the need to stop and wait, and achieving efficient continuous production. Through this dual-box alternating operation mode, not only is the tiered utilization of heat energy achieved, but the energy consumption of a single temperature control box 1 is also reduced. The preheating stage has already removed some moisture, reducing the time and energy consumption required for subsequent roasting, and the overall energy efficiency is significantly improved.

The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field.
