Description

Technical Field

[0001] The utility model relates to the technical field of tsaoko drying and processing, in particular to an energy-saving drying device for tsaoko. Background Art

[0002] Amomum tsao-ko (Crevost et Lemaire) is a perennial, evergreen, clump-forming herb in the Zingiberaceae family. Its fruit has a unique aroma and medicinal properties, making it a valuable spice and traditional Chinese medicine. After harvesting, the fresh fruit has a moisture content of up to 75%. Drying is required to reduce this moisture content to less than 13% for transportation, storage, and market distribution.

[0003] At present, cardamom is usually dried using traditional earth kilns, mesh belt dryers or box dryers. These three types of equipment do not have heat recovery devices. During the drying process, when the cardamom comes into contact with hot air, the dry hot air becomes moist and hot and is directly discharged. The heat energy only heats the cardamom once and cannot be reused. This greatly wastes resources and leads to high energy consumption and high cost in cardamom processing.

[0004] Therefore, the research and development of an energy-saving drying device that can effectively recover heat and reduce energy consumption will not only help save energy and reduce costs, but also promote the sustainable development of the tsaoko industry. Furthermore, the successful development and application of such innovative technologies can provide a useful reference for the processing of other agricultural products and traditional Chinese medicines, promoting technological progress across the entire agricultural industry chain and generating significant economic and social benefits. Utility Model Content

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides an energy-saving drying device and method for tsaoko, which can evenly dry the tsaoko and recycle waste heat during the drying process. This device has the advantages of energy conservation, high thermal efficiency, low operating costs, and good economic benefits. It promotes the effective utilization of resources and environmental protection, and solves the problems of heat waste and high processing costs in current tsaoko drying equipment.

[0007] (2) Technical solution

[0008] In order to achieve the above-mentioned purpose of uniformly drying the tsaoko and recycling the waste heat during the drying process, thereby improving the utilization rate of thermal energy and saving energy, the utility model provides the following technical solutions: an energy-saving drying device for tsaoko, comprising a drying chamber, a plurality of hot air blowers are installed at the bottom of the drying chamber, a pillow plate is fixedly installed on the inner bottom surface of the drying chamber, a conveying unit is installed on the top surface of the pillow plate, an air outlet hood is installed on the top surface of the drying chamber, an air supply pipe is fixedly connected to the top of the air outlet hood, a No. 1 three-way valve is installed at one end of the air supply pipe, a dehumidification device is connected to each of the two ends of the No. 1 three-way valve, an axial flow fan is installed at the back of the drying chamber, a detection tube is fixedly connected to the outer surface of the axial flow fan, a humidity sensor is installed on the outer surface of the detection tube, a return pipe is installed at one end of the detection tube, and a No. 2 three-way valve is installed at one end of the return pipe;

[0009] The dehumidification device includes a dehumidification box, an inner tank, a filter plate, a molecular sieve, a box cover, an exhaust valve, an induction coil, a connecting pipe and an air outlet pipe. The inner tank is arranged inside the dehumidification box, the filter plate is installed inside the inner tank, and the inner tank is filled with molecular sieves. The box cover is installed on the top of the dehumidification box, the exhaust valve and the connecting pipe are installed on the top surface of the box cover, the outer surface of the inner tank is sleeved with the induction coil, and the air outlet pipe is installed at the bottom of the dehumidification box.

[0010] Preferably, a discharge port is opened through the top of the drying chamber, a discharge hopper is installed at the position of the discharge port, the interior of the discharge hopper is rotatably connected to a material distribution roller, and one end of the material distribution roller is connected to the output shaft of motor No. 1.

[0011] Through the above technical solution, the cardamom needs to go through a cleaning process before drying, and the cleaned cardamom is transported to the lower hopper for temporary storage using conveying equipment. By starting the No. 1 motor, the material dividing roller can be driven to rotate. During the rotation of the material dividing roller, the cardamom in the lower hopper can be gradually transported to a mesh belt conveyor located at the top. In this way, gradual unloading can be achieved, making it easier for the cardamom to be spread flat on the mesh belt conveyor.

[0012] Preferably, an inclined plate is installed on the inner top surface of the drying chamber by bolts, and the inclined plate is located below the material discharge port of the drying chamber. A plurality of inspection doors are installed on the front of the drying chamber.

[0013] Through the above technical solution, when the cardamom falls from the lower hopper, it will fall onto the inclined plate, which can guide the cardamom to the mesh belt conveyor, thereby preventing the cardamom from being scattered on the inner bottom surface of the drying chamber.

[0014] Preferably, the conveyor group includes at least three mesh belt conveyors, support rods are fixedly connected to the frames of the mesh belt conveyors, and a discharge port is provided at the bottom of the drying chamber.

[0015] Through the above technical solution, by turning on the hot air blower to send hot air upward from the bottom of the drying chamber, the hot air can pass through the mesh belt of the mesh belt conveyor and be transmitted upward, so that the cardamom on the mesh belt conveyor can be baked. After falling from the lower hopper, the cardamom first falls onto the mesh belt conveyor located at the top, and then falls onto the middle mesh belt conveyor after being conveyed, and finally falls onto the bottom mesh belt conveyor. In this way, the drying time of the cardamom can be maximized in a limited space, so that the cardamom can be fully dried. After drying, the cardamom falls from the discharge port, and a conveyor belt can be set below the discharge port to transport the dried cardamom.

[0016] Preferably, the conveyor unit further comprises a support plate mounted on the mesh belt conveyor frame by bolts, the outer surface of the support plate is fixedly connected to a connecting rod, and the outer surface of the connecting rod is fixedly connected to a material blocking plate.

[0017] Through the above technical solution, support rods are set up to connect and support each mesh belt conveyor. When the cardamom falls from one of the mesh belt conveyors, it will fall onto the baffle plate, and the cardamom can be guided to a mesh belt conveyor below through the baffle plate.

[0018] Preferably, both ends of the No. 1 three-way valve are connected to a connecting pipe, the top surface of the filter plate contacts the molecular sieve, and the end of the outlet pipe away from the dehumidification box is connected to the No. 2 three-way valve.

[0019] Through the above technical solution, the hot air generated by the hot air blower bakes the cardamom, and the dry hot air gradually rises to the top of the interior of the drying chamber. After heat exchange, the dry hot air still has a certain amount of heat and becomes humid hot gas and enters the air outlet hood. Then it enters the dehumidification box through the air supply pipe, No. 1 three-way valve and the connecting pipe. The humid hot gas absorbs moisture through the molecular sieve and becomes dry again. By starting the axial flow fan, negative pressure is generated in the detection tube and the return pipe, which can absorb the dry gas inside the dehumidification box and enter the drying chamber again. The overall structure can reuse the waste heat generated in the drying process, thereby saving energy.

[0020] Preferably, a spiral tube is provided on the outer surface of the detection tube, the inner thread of the spiral tube is connected to the humidity sensor, and the probe of the humidity sensor is located inside the detection tube.

[0021] Through the above technical solution, the hot and humid gas will pass through the detection tube after dehumidification, so that the humidity sensor can detect it. If the detection result exceeds the set threshold, it indicates that the adsorption of the molecular sieve is saturated. At this time, the gas flow direction is switched through the No. 1 three-way valve and the No. 2 three-way valve, so that another dehumidification device starts to dehumidify the hot and humid gas again.

[0022] Preferably, the dehumidification box further includes a controller installed on the outer surface of the dehumidification box, and two groups of dehumidification devices are provided.

[0023] Through the above technical solution, when the molecular sieve inside one of the dehumidification devices is saturated with adsorption, the hot and humid gas can be dehumidified through another dehumidification device. The controller is an electromagnetic controller, which converts low-frequency alternating current into high-frequency alternating current. By connecting to the induction coil, an alternating electromagnetic field is generated, which can generate eddy currents inside the inner tank and generate heat. After the heat is generated in the inner tank, it will be transferred to the molecular sieve inside. In this way, the molecular sieve can become dry again after rapid heating, so that the molecular sieve can be reused and the evaporated gas can be released by opening the exhaust valve.

[0024] Preferably, a No. 2 motor is installed at the bottom of the dehumidification box body, and the output end of the No. 2 motor is connected to a stirring rod, and the stirring rod is located inside the inner tank.

[0025] Through the above technical solution, when the molecular sieve is dehumidified, the stirring rod can be driven to rotate by starting the No. 2 motor. The molecular sieve is stirred during the rotation of the stirring rod, so that the molecular sieve can be evenly heated and the water absorbed inside can be quickly evaporated. This helps the molecular sieve to be evenly heated and the water inside can be quickly evaporated.

[0026] Compared with the prior art, the present invention provides an energy-saving drying device for tsaoko, which has the following beneficial effects:

[0027] 1. The utility model provides an energy-saving drying device for tsaoko, which is equipped with two sets of dehumidification devices. A hot air blower is used to send hot air into the drying chamber to bake the tsaoko. During the drying process, the hot air rises and is eventually discharged from the air outlet hood, and enters the dehumidification box through the air supply pipe and the No. 1 three-way valve. The hot and humid gas is dehumidified by the analytical sieve and becomes dry. Then, the dry hot gas is returned to the drying chamber again through the axial flow fan and the return pipe. In this way, the waste heat generated during drying can be utilized, thereby reducing energy consumption.

[0028] 2. The utility model provides an energy-saving drying device for tsaoko. When the molecular sieve inside one of the dehumidification devices is saturated with adsorption, another dehumidification device can be used to dehumidify the hot and humid gas. By starting the controller, low-frequency alternating current is converted into high-frequency alternating current, and an alternating electromagnetic field is generated by connecting to the induction coil, which can generate eddy currents inside the inner tank and generate heat. After the heat is generated in the inner tank, it will be transferred to the molecular sieve inside. In this way, the molecular sieve can become dry again after rapid heating, so that the molecular sieve can be reused and the evaporated gas can be released by opening the exhaust valve.

[0039] The dehumidification device 8 includes a dehumidification box 81, an inner liner 82, a filter plate 83, a molecular sieve 84, a box cover 85, an exhaust valve 86, an induction coil 87, a connecting pipe 88 and an air outlet pipe 89. The inner liner 82 is arranged inside the dehumidification box 81, the filter plate 83 is installed inside the inner liner 82, and the inner liner 82 is filled with molecular sieve 84. The box cover 85 is installed on the top of the dehumidification box 81, the exhaust valve 86 and the connecting pipe 88 are installed on the top surface of the box cover 85, the outer surface of the inner liner 82 is sleeved with the induction coil 87, and the air outlet pipe 89 is installed at the bottom of the dehumidification box 81.

[0040] Specifically, a discharge port is provided through the top of the drying chamber 1, and a discharge hopper 14 is installed at the position of the discharge port. The interior of the discharge hopper 14 is rotatably connected to a distribution roller 15, and one end of the distribution roller 15 is connected to the output shaft of a No. 1 motor 16. The advantage is that the tsaoko needs to go through a cleaning process before drying, and the cleaned tsaoko is transported to the discharge hopper 14 for temporary storage using a conveying device. By starting the No. 1 motor 16, the distribution roller 15 can be driven to rotate. During the rotation of the distribution roller 15, the tsaoko in the discharge hopper 14 can be gradually transported to a mesh belt conveyor 41 located at the top. In this way, gradual discharge can be achieved, making it easier for the tsaoko to be spread flat on the mesh belt conveyor 41.

[0041] Specifically, a ramp 17 is bolted to the interior ceiling of the drying chamber 1. This ramp 17 is located below the feed opening of the drying chamber 1, and a plurality of access doors 21 are installed on the front of the drying chamber 1. Advantageously, when the tsaoko falls from the feed hopper 14, it lands on the ramp 17, which guides it onto the mesh belt conveyor 41, thereby preventing the tsaoko from scattering onto the interior floor of the drying chamber 1.

[0042] Specifically, the conveyor group 4 includes at least three mesh belt conveyors 41, and the support rods 42 are fixedly connected to the frames of the mesh belt conveyors 41. The discharge port 18 is provided at the bottom of the drying chamber 1. The advantage is that by turning on the hot air blower 2 to send hot air upward from the bottom of the drying chamber 1, the hot air can pass through the mesh belt of the mesh belt conveyor 41 and be transmitted upward, so that the cardamom on the mesh belt conveyor 41 can be baked. After falling from the lower hopper 14, the cardamom first falls onto the top mesh belt conveyor 41, and then falls onto the middle mesh belt conveyor 41 after being conveyed, and finally falls onto the bottom mesh belt conveyor 41. In this way, the baking time of the cardamom can be maximized in a limited space, so that the cardamom can be fully dried. After drying, the cardamom falls from the discharge port 18, and a conveyor belt can be provided below the discharge port 18 to transport the dried cardamom.

[0043] Specifically, the conveyor assembly 4 further includes a support plate 43 mounted on the frame of the mesh belt conveyor 41 by bolts. The outer surface of the support plate 43 is fixedly connected to a connecting rod 44, and the outer surface of the connecting rod 44 is fixedly connected to a material retaining plate 45. The advantage is that by providing the support rod 42 for connecting and supporting each mesh belt conveyor 41, when the grass fruit falls from one mesh belt conveyor 41, it will fall onto the material retaining plate 45, and the material retaining plate 45 can guide the grass fruit to the mesh belt conveyor 41 below.

[0044] Specifically, each end of the No. 1 three-way valve 7 is connected to a connecting pipe 88, the top surface of the filter plate 83 contacts the molecular sieve 84, and the end of the air outlet pipe 89 away from the dehumidification box 81 is connected to the No. 2 three-way valve 13. The advantage is that, during the process of baking the tsaoko with the hot air generated by the hot air blower 2, the dry hot air gradually rises to the upper part of the drying chamber 1. After heat exchange, the dry hot air still has a certain amount of heat and becomes humid hot gas and enters the air outlet hood 5. Then, it enters the dehumidification box 81 through the air supply pipe 6, the No. 1 three-way valve 7 and the connecting pipe 88. The humid hot gas absorbs moisture through the molecular sieve 84 and becomes dry again. By starting the axial flow fan 9, negative pressure is generated in the detection tube 10 and the return pipe 12, which can absorb the dry gas inside the dehumidification box 81 and re-enter the drying chamber 1. The overall structure can reuse the waste heat generated during the drying process, thereby saving energy.

[0045] Specifically, a spiral tube is provided on the outer surface of the detection tube 10, the inner thread of which is connected to the humidity sensor 11. The probe of the humidity sensor 11 is located inside the detection tube 10. The advantage is that after dehumidification, the hot and humid gas will pass through the detection tube 10, so that the humidity sensor 11 can detect it. If the detection result exceeds the set threshold, it indicates that the molecular sieve 84 is adsorbed saturated. At this time, the gas flow direction is switched through the No. 1 three-way valve 7 and the No. 2 three-way valve 13, so that the other dehumidification device 8 begins to dehumidify the hot and humid gas.

[0046] Specifically, the dehumidification box 81 further includes a controller 810 mounted on the outer surface of the dehumidification box 81, and two groups of dehumidification devices 8 are provided. The advantage is that when the molecular sieve 84 inside one of the dehumidification devices 8 is saturated with adsorption, the other dehumidification device 8 can start to dehumidify the hot and humid gas. The controller 810 is an electromagnetic controller. The controller 810 converts low-frequency alternating current into high-frequency alternating current, and generates an alternating electromagnetic field by connecting to the induction coil 87, which can generate eddy currents inside the inner liner 82 and generate heat. After the heat generated by the inner liner 82, it will be transferred to the molecular sieve 84 inside. In this way, the molecular sieve 84 can become dry again after being rapidly heated, so that the molecular sieve 84 can be reused and the evaporated gas can be released by opening the exhaust valve 86.

[0047] Specifically, a second motor 19 is mounted at the bottom of the dehumidification housing 81. The output end of the second motor 19 is connected to a stirring rod 20, which is located inside the inner container 82. Advantageously, when dehumidifying the molecular sieve 84, the second motor 19 can be activated to drive the stirring rod 20 to rotate. During the rotation of the stirring rod 20, the molecular sieve 84 is agitated, which allows the molecular sieve 84 to be evenly heated and quickly evaporates the moisture absorbed therein. This helps the molecular sieve 84 to be evenly heated and quickly evaporate the moisture inside.

[0048] The working principle and method of the energy-saving drying device for Amomum villosum of the utility model are as follows:

[0049] S1, transport the cleaned tsaoko into the discharge hopper 14, and discharge the tsaoko onto the mesh belt of the mesh belt conveyor 41 through the No. 1 motor 16 and the material distribution roller 15;

[0050] S2, transporting the tsaoko via a plurality of mesh belt conveyors 41 and starting the hot air blower 2 to deliver hot air into the drying chamber 1 to dry the tsaoko;

[0051] S3, the hot and humid gas generated during the drying process of the tsaoko rises to the top of the drying chamber 1, then enters the inner tank 82 through the gas outlet hood 5 and the gas pipe 6, and is filtered out of moisture by the molecular sieve 84;

[0052] S4, by starting the axial flow fan 9, the dehumidified dry hot air flows back to the drying chamber 1 through the outlet pipe 89, the No. 2 three-way valve 13, the return pipe 12 and the detection pipe 10 for reuse;

[0053] S5. The humidity sensor 11 detects the dryness of the gas flowing into the detection tube 10. If the gas is moist, the No. 1 three-way valve 7 and the No. 2 three-way valve 13 are operated to switch the flow direction of the moist hot gas, so that the other dehumidification device 8 dehumidifies the moist hot gas again.

[0054] S6. The inner container 82 generates heat by starting the induction coil 87. The moisture-saturated molecular sieve 84 decomposes the moisture after being heated and is discharged through the exhaust valve 86.
