Technical Field
[0001] The invention relates to the technical field of tea processing equipment, in particular to a continuous air drying device and method for coffee peel tea. Background Art
[0002] Coffee cascara tea is an emerging beverage, and the drying process is crucial in its production. Traditional drying equipment often uses a single drying method, such as natural air drying or simple hot air drying. Natural air drying is greatly affected by environmental factors and has a slow drying speed; the hot air drying equipment is not designed reasonably, and the heat distribution is uneven, resulting in a long drying time. Naturally dried tea may take several days to reach the appropriate dryness. If the hot air drying does not have a good air circulation design, local overheating or overcooling will greatly reduce the drying efficiency. The structure of traditional drying equipment may not ensure that the material is evenly heated or ventilated during the drying process. This will cause part of the material to be over-dried, and part of it has not yet reached the drying requirements, resulting in the outer layer being dry and cracked during the drying process, and the inner layer still containing moisture.

[0011] A continuous air drying device for coffee cascara tea and a method for using the same include the following steps: S1. Check whether all parts of the equipment are firmly installed, including the air energy heat pump, motor 1, motor 2, conveyor belt, roller, combing and cleaning components, and ensure that the connecting pipe, ventilation pipe, air nozzle, ventilation slot, air outlet 1 and air outlet 2 and other ventilation parts are not blocked and can be ventilated normally; S2, start motor 1, which drives shaft 1 to rotate, thereby rotating the auger blades, and the auger blades transport the materials in the feed hopper to the upper surface of the conveyor belt through the feed pipe; S3, start the air energy heat pump, the hot air generated by the air energy heat pump enters the ventilation slot in the baffle through the connecting pipe, and the hot air is blown out from the air nozzle of the ventilation pipe, the second air outlet hole of the roller and the first air outlet hole of the conveyor belt to dry the materials on the conveyor belt; S4, start the second motor, the second motor drives the roller to rotate, and then the conveyor belt runs, the conveyor belt conveys the material to the discharge hopper, the second motor drives the third shaft to rotate through the second pulley, the first belt, and the first pulley, the roller brush on the third shaft cleans the conveyor belt, the third pulley drives the second shaft to rotate through the second belt and the fourth pulley, and the combing teeth on the second shaft comb the material on the conveyor belt to make the material evenly distributed and better accepted for drying; S5. After drying, combing and conveying, the material reaches the discharge hopper, and the material is discharged from the box through the discharge hopper, completing the drying process.
[0012] Working principle: The air energy heat pump absorbs heat from the air and generates hot air. The hot air enters the baffle ventilation slot inside the box through the connecting pipe, and then blows out through the air nozzle on the ventilation pipe and the air outlet of the roller and the conveyor belt, forming a full-range hot air circulation to dry the materials on the conveyor belt. The material enters the shell from the feed hopper, and the motor drives the shaft to rotate, so that the auger blades convey the material to the surface of the conveyor belt through the feed pipe. The conveyor belt is driven by the motor two to drive the roller to rotate. During the conveying process, on the one hand, the motor two drives the roller brush on the shaft three through the belt drive to clean the lower surface of the conveyor belt. On the other hand, another set of belt drives the combing teeth on the shaft two to comb the materials on the conveyor belt to ensure that the materials are evenly distributed and better accepted for drying. The dried materials move with the conveyor belt to the discharge hopper and are discharged from the box through the discharge hopper. If the material falls from the conveyor belt or falls from the air outlet during the conveying process, the guide plate and the receiving hopper will guide it to the conveying device for re-drying. The baffle is fixed to the bottom of the inner wall of the box by the second leg, and the box is supported by the first leg, so as to ensure the stability of the whole equipment during operation and ensure that all parts work together to achieve continuous, efficient and uniform drying of coffee peel tea.
[0013] The present invention provides a continuous air drying device and method for coffee peel tea, which has the following beneficial effects: 1. The present invention generates hot air through an air energy heat pump, and with the help of connecting pipes, ventilation pipes, air nozzles, rollers and air outlets of a conveyor belt, a uniform and efficient hot air circulation system is constructed, so that the material can be dried uniformly in all directions during the conveyor belt transportation process, which not only ensures the high efficiency of drying, improves production efficiency, ensures the continuity of material transportation, but also ensures the consistency of drying quality. At the same time, the equipment structure is reasonably designed, which is conducive to stable operation, and provides a strong guarantee for the high-quality drying of coffee peel tea.
[0014] 2. The present invention drives the roller to rotate through motor 2, and with the help of pulley and belt transmission, drives the rotating shaft 3 and the roller brush located below the conveyor belt to clean the conveyor belt and remove impurities. At the same time, it drives the rotating shaft 2 and the combing teeth located above the conveyor belt to comb the materials on the conveyor belt to make their distribution more uniform. The two work together to ensure the good operation of the conveyor belt and improve the uniformity of material drying and the overall drying quality, which is conducive to the equipment to continuously, stably and efficiently complete the drying work of coffee peel tea.
[0015] 3. The present invention drives the auger blades to rotate through a motor-driven rotating shaft, so that the material placed in the feed hopper can be stably and orderly transported to the upper surface of the conveyor belt through the channel in the outer shell and the feed pipe, thereby realizing the continuous supply of materials, accurately controlling the material conveying amount and speed, ensuring the uniformity and continuity of the material when entering the drying link, avoiding material accumulation or insufficient supply, etc., laying the foundation for the subsequent efficient and uniform drying of coffee peel tea, and effectively improving the overall production efficiency.

DETAILED DESCRIPTION
[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0019] Please refer to the attached Figure 1 -Attached Figure 2 , Attachment Figure 4 -Attached Figure 8 The embodiment of the present invention provides a continuous air-energy drying device and method for coffee peel tea, comprising a box body 1, an air-energy heat pump 2 is arranged on one side of the upper surface of the box body 1, a connecting pipe 3 is fixedly arranged on one side of the air-energy heat pump 2, the connecting pipe 3 passes through the box body 1 and is fixedly arranged with a baffle 16, a ventilation pipe 18 is fixedly arranged on one end of the connecting pipe 3, a plurality of air nozzles 19 are arranged on the bottom end of the outer wall of the ventilation pipe 18, the top end of the outer wall of the ventilation pipe 18 is fixedly arranged on the bottom end of the inner wall of the box body 1, baffles 16 are symmetrically arranged inside the box body 1, a ventilation slot 35 is arranged inside the baffle 16, a plurality of rollers 23 are rotatably connected to the side wall of the baffle 16, a cavity is arranged inside the roller 23, a plurality of air outlet holes 24 are arranged on the outer wall of the roller 23, a conveyor belt 15 is arranged on the outer wall of the roller 23, a plurality of air outlet holes 1 22 are arranged on the outer wall of the conveyor belt 15, the cavity of the roller 23 is communicated with the ventilation slot 35 of the baffle 16, and a combing and cleaning component is fixedly arranged on one end of one of the rollers 23.
[0020] Specifically, the air energy heat pump 2, as the core heat supply unit, operates based on the reverse Carnot cycle principle. It absorbs low-grade heat energy from the surrounding air, compresses and works through the compressor, increases the temperature and pressure of the refrigerant, and then transfers the heat to the circulating air flow, generating high-temperature hot air, which is introduced into the box body 1 through the connecting pipe 3. After entering the box body, the hot air first reaches the channel of the baffle 16, and then distributes along the ventilation pipe 18. The several air nozzles 19 at the bottom of the ventilation pipe 18 can spray the hot air onto the conveyor belt 15 below in a uniform and dispersed manner, ensuring that the coffee peel and tea materials on the conveyor belt 15 can be evenly heated. At the same time, the hot air will also flow into the ventilation slot 35 provided inside the baffle 16. Since the roller 23 is rotatably connected to the side wall of the baffle 16 and the cavity of the roller 23 is connected to the ventilation slot 35, the hot air can enter the internal cavity of the roller 23 and blow out from the air outlet 24 on the outer wall of the roller 23 at multiple angles, cooperating with the hot air blown out from the air nozzle 19 to form an all-round hot air wrapped environment. In addition, the hot air will also be transmitted from the air outlet 1 22 on the outer wall of the conveyor belt 15, further enhancing the contact probability between the upper and lower surfaces of the material and the hot air, making the drying process of the material more efficient and uniform. The motor drives the roller 23 to rotate, driving the conveyor belt 15 to run. After the material enters the starting end of the conveyor belt 15 through the feeding device, it moves from the feeding end to the discharging end with the conveyor belt 15, and is continuously dried by hot air during this period. The ventilation system in the equipment discharges wet air to maintain a stable drying environment. The material conveying speed matches the hot air drying capacity, ensuring that the material reaches an ideal drying degree when it leaves the discharging end.
[0021] Through transportation and drying, the heat distribution in each area inside the box 1 is balanced, and the materials at the center or edge of the conveyor belt 15 can receive the same amount of heat in the same time, which greatly improves the continuity, efficiency and uniformity of the drying process. It effectively solves the problems of uneven hot air distribution, low and uneven static drying efficiency of materials, inability to produce continuously and unstable product quality in traditional drying equipment.
[0022] Please refer to the attached Figure 5 -Attached Figure 7The combing and cleaning component includes a motor 2 13, an output end of the motor 2 13 is fixedly arranged at one end of one of the rollers 23, a pulley 2 30 is fixedly arranged at one end of the roller 23, a belt 1 29 is connected inside the pulley 2 30, one end of the belt 1 29 is connected to a pulley 1 28, a rotating shaft 3 27 is fixedly arranged in the middle of the pulley 1 28, the rotating shaft 3 27 passes through the guide plate 21 and is rotatably connected to a fixed block 25, the top of the fixed block 25 is fixedly arranged at the bottom end of the baffle 16, a plurality of roller brushes 34 are arranged on the outer wall of the rotating shaft 3 27, the rotating shaft 3 27 is located below the conveyor belt 15, a pulley 3 31 is fixedly arranged on one side of the roller 23, a belt 2 32 is connected inside the pulley 3 31, a pulley 4 33 is connected at one end of the belt 2 32, a rotating shaft 20 is fixedly arranged in the middle of the pulley 4 33, the rotating shaft 20 passes through the baffle 16 and is rotatably connected above the conveyor belt 15, and a plurality of combing teeth 26 are fixedly arranged on the outer wall of the rotating shaft 20.
[0023] Specifically, the combing and cleaning component relies on the motor 2 13 to provide a power source. The output end of the motor 2 13 is fixedly connected to one end of one of the rollers 23. When the motor 2 13 starts to run, it directly drives the roller 23 connected thereto to rotate. One end of the roller 23 is fixedly provided with a pulley 2 30. As the roller 23 rotates, the pulley 2 30 also rotates synchronously. The pulley 2 30 is connected to the pulley 1 28 through the internally connected belt 1 29 to achieve transmission connection. In this way, the pulley 1 28 will rotate under the drive of the belt 1 29. The middle part of the pulley 1 28 is fixedly provided with a rotating shaft 3 27, and the rotating shaft 3 27 rotates with the rotation of the pulley 1 28. A pulley 3 31 is also fixedly provided on one side of the roller 23. During the rotation of the roller 23, the pulley 3 31 also rotates accordingly, and relies on the internally connected belt 2 32 to transmit power to the pulley 4 33, driving the pulley 4 33 to rotate, and the rotating shaft 2 20 fixed in the middle part of the pulley 4 33 also rotates accordingly.
[0024] The third rotating shaft 27 penetrates the guide plate 21 and is rotatably connected to the fixed block 25. The third rotating shaft 27 is located below the conveyor belt 15. The roller brushes 34 arranged on the outer wall thereof rotate with the rotation of the third rotating shaft 27. During the rotation process, the roller brushes 34 contact the lower surface of the conveyor belt 15, and can brush away dust, fine materials and other impurities contaminated by the conveyor belt 15 during the material conveying process. The second rotating shaft 20 penetrates the baffle 16 and is rotatably connected above the conveyor belt 15. The combing teeth 26 fixedly arranged on the outer wall thereof continuously comb the coffee peel and tea materials being conveyed on the conveyor belt 15 as the second rotating shaft 20 rotates, so that the materials are more evenly distributed on the conveyor belt 15, and the materials are prevented from piling up and affecting the drying effect.
[0025] The roller brush 34 driven by the rotating shaft 3 27 continuously brushes and cleans the lower surface of the conveyor belt 15, which can effectively remove various impurities accumulated during the long-term operation of the conveyor belt 15 and keep the lower surface of the conveyor belt 15 clean. The combing teeth 26 on the rotating shaft 20 are used to comb the coffee peel and tea materials on the conveyor belt 15, so that the materials are evenly dispersed on the conveyor belt 15, ensuring that all parts of the materials can receive uniform heat for drying. This solves the problem of uneven drying caused by the accumulation and uneven distribution of materials during the material transmission and drying process. The roller brush 34 of the combing and cleaning component can automatically and continuously perform cleaning work, greatly reducing the burden of manual maintenance and improving the cleanliness of the equipment.
[0026] Please see attached Figure 1 -Attached Figure 2 , Attachment Figure 5 -Attached Figure 6 The bottom end of the baffle 16 is fixedly arranged on the top end of the guide plate 21, a discharge hopper 14 is fixedly arranged at one end of the baffle 16, an outer wall of the discharge hopper 14 is arranged on the outer wall of the box body 1, a receiving hopper 7 is fixedly arranged at one end of the guide plate 21, and a conveying device is arranged on one side of the outer wall of the receiving hopper 7 that passes through the box body 1.
[0027] Specifically, when the material is being conveyed and dried on the conveyor belt 15, it is inevitable that the material will fall from the conveyor belt 15 due to the vibration of the equipment and the characteristics of the material itself, and will also fall from the air outlet 22 on the conveyor belt 15. At this time, the guide plate 21 located below the conveyor belt 15 plays a role, and its inclined design allows the fallen material to slide along the surface of the guide plate 21 into the receiving hopper 7. The receiving hopper 7 then conveys the collected material to the feed pipe 9 again through the connection channel between it and the conveying device, and then returns to the conveyor belt 15, realizing the collection and secondary drying cycle of the fallen material, ensuring that the material will not be wasted and can be fully dried.
[0028] It realizes the effective recovery and secondary drying of materials that may fall, avoids material waste, improves material utilization, improves the overall drying efficiency of the equipment, and reduces the need for re-drying due to incomplete drying of some materials, thereby achieving energy saving and efficiency improvement. It solves the problem of material waste caused by the inability to recycle materials that fall in traditional drying equipment, and the problem that some materials are discarded because they are not fully dried, thus affecting the overall drying effect and product quality.
[0029] Please see attached Figure 1 -Attached Figure 3The conveying device includes a feed pipe 9, one end of which passes through the box body 1 and is arranged on the upper surface of the conveyor belt 15, the other end of the feed pipe 9 is fixedly provided with a shell 8, the interior of the shell 8 is rotatably connected with a rotating shaft 10, one end of the rotating shaft 10 is provided with a motor 11, the bottom end of the shell 8 is fixedly provided with a base 5, the outer wall of the shell 8 is provided with a feed hopper 6, and the outer wall of the rotating shaft 10 is fixedly provided with an auger blade 17.
[0030] Specifically, the material is poured into the feed hopper 6, which serves as the initial collection container for the material and collects the material. Subsequently, the motor 11 is started to drive the rotating shaft 10 to rotate. Since the outer wall of the rotating shaft 10 is fixedly provided with an auger blade 17, the auger blade 17 will rotate synchronously with the rotation of the rotating shaft 10. Under the rotation of the auger blade 17, the material in the housing 8 is pushed by the blade and moves along the internal channel of the housing 8 toward the feed pipe 9. Finally, the material is transported to the upper surface of the conveyor belt 15 through the feed pipe 9, completing the material transportation process from the feed hopper 6 to the conveyor belt 15, so that the material can enter the subsequent drying process.
[0031] The materials can be transported at a certain speed and flow rate by the rotation of the auger blades 17, thus avoiding blockage or interruption in the material transport process, ensuring the continuous operation of the entire drying equipment, and improving production efficiency. This solves the problems of unstable material flow and uneven distribution that may occur in the material transport process of traditional drying equipment.
[0032] Please see attached Figure 1 -Attached Figure 2 , Attachment Figure 5 A plurality of legs 12 are fixedly arranged at the bottom end of the baffle 16, the bottom end of the legs 12 is arranged at the bottom end of the inner wall of the box body 1, and a plurality of legs 14 are arranged at the bottom end of the box body 1.
[0033] Specifically, the baffle 16 is connected to the bottom of the inner wall of the box body 1 through a plurality of legs 12, one end of the legs 12 is fixed to the bottom of the baffle 16, and the other end is stably placed on the bottom of the inner wall of the box body 1, thereby providing vertical support for the baffle 16, so that it can maintain a fixed position and posture inside the box body 1. At the same time, a plurality of legs 14 arranged at the bottom of the box body 1 are in contact with the ground or the supporting plane, bearing the weight of the entire box body 1 and its internal equipment components, and evenly distributing the gravity of the equipment to the supporting plane, ensuring that the equipment will not tilt, shake or shift due to uneven gravity distribution during operation.
[0034] The baffle 16 is stably supported in the box body 1 and the box body 1 is stably placed as a whole, which effectively maintains the relative position relationship between the internal components of the equipment and ensures the structural integrity and stability of the equipment during operation.
[0035] Please see attached Figure 1 -Attached Figure 8 , a continuous air drying device for coffee cascara tea and a method for using the same, comprising the following steps: S1. Check whether all parts of the equipment are firmly installed, including the air energy heat pump 2, motor 11, motor 2 13, conveyor belt 15, roller 23, combing and cleaning components, and ensure that the ventilation parts such as the connecting pipe 3, ventilation pipe 18, air nozzle 19, ventilation slot 35, air outlet 1 22 and air outlet 2 24 are not blocked and can be ventilated normally; S2, start the motor 11, the motor 11 drives the rotating shaft 10 to rotate, so that the auger blade 17 rotates, and the auger blade 17 transports the material in the feed hopper 6 to the upper surface of the conveyor belt 15 through the feed pipe 9; S3, start the air energy heat pump 2, the hot air generated by the air energy heat pump 2 enters the ventilation slot 35 in the baffle 16 through the connecting pipe 3, and the hot air is blown out from the air nozzle 19 of the ventilation pipe 18, the second air outlet 24 of the roller 23 and the first air outlet 22 of the conveyor belt 15 to dry the materials on the conveyor belt 15; S4, start the second motor 13, the second motor 13 drives the roller 23 to rotate, and then the conveyor belt 15 runs, the conveyor belt 15 conveys the material to the discharge hopper 14, the second motor 13 drives the third shaft 27 to rotate through the second pulley 30, the first belt 29, and the first pulley 28, the roller brush 34 on the third shaft 27 cleans the conveyor belt 15, the third pulley 31 drives the second shaft 20 to rotate through the second belt 32 and the fourth pulley 33, and the combing teeth 26 on the second shaft 20 comb the material on the conveyor belt 15 to make the material evenly distributed and better accepted by drying; S5. After being dried, combed and conveyed, the material reaches the discharge hopper 14, and the material is discharged from the box 1 through the discharge hopper 14, completing the drying process.
[0036] Specifically, visual inspection and manual testing of equipment components are carried out manually to check the installation and fixation of key components, rotate movable components to check flexibility, use simple methods to detect whether the airflow of ventilation components is smooth, and judge the status of each component and ventilation path. Ensure that the equipment is in good condition before startup, reduce potential faults, improve reliability and safety, and extend service life.
[0037] When the motor 11 is powered on, the magnetic field drives the rotor to rotate the shaft 10, and the auger blade 17 rotates accordingly, pushing the material in the feed hopper 6 to the surface of the conveyor belt 15 through the feed pipe 9. It realizes efficient and stable material transportation, accurately controls the transportation volume and speed, ensures stable material supply, and improves production controllability and stability.
[0038] The air energy heat pump starts to absorb energy and generate heat according to the reverse Carnot cycle. The hot air enters the ventilation slot 35 through the connecting pipe and is blown out from multiple places, surrounding the material to evaporate its moisture. This achieves efficient and uniform drying, improves drying speed and quality consistency, reduces energy consumption, improves energy utilization efficiency, and reduces costs.
[0039] The motor 2 13 drives the roller 23, drives the conveyor belt 15, and through the transmission, the roller brush 34 of the rotating shaft 3 27 cleans the conveyor belt 15, and the combing teeth 26 of the rotating shaft 20 disperse the materials. Continuous combing and cleaning of the materials is achieved, ensuring uniform distribution and cleaning of the conveyor belt 15, improving drying uniformity and stability, and improving product quality and production efficiency.
[0040] The dried material is conveyed along the conveyor belt 15 to the top of the discharge hopper 14, falls into the discharge hopper 14 under the action of gravity and is discharged from the box. The material is discharged and collected smoothly, ensuring continuous and smooth production, facilitating subsequent processing, reducing the risk of material contamination and moisture, and stabilizing product quality.
[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
