[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses an air-source dehumidifying and drying room for fruits, vegetables, and medicinal herbs. The air-source dehumidifying and drying room mainly includes a drying chamber 1, a protective shell 2, an air inlet duct 3, a return air duct 4, a dehumidifying fan 5, a partition 6, an air inlet fan 7, a material trolley 8, an external rotor fan 9, an evaporator 10, a compressor 11, a condenser 12, a regenerator 13, and a controller 14. The drying chamber 1 has a hollow internal structure with a movable door 15 at the front. An air inlet is located at the top of the side wall of the drying chamber 1, and a return air inlet is located at the bottom of the side wall. The protective shell 2 is installed at the end of the drying chamber 1. The bottom of the air inlet duct 3 is connected to the top of the protective shell 2, and the top is connected to the air inlet of the drying chamber 1. One end of the return air duct 4 is connected to the protective shell 2, and the other end is connected to the return air inlet of the drying chamber 1. The dehumidifying fan 5 is installed at the return air inlet. The partition 6... Plate 6 is installed inside the drying chamber 1, dividing the drying chamber 1 into an air intake chamber 16 and a drying chamber 17. The rightmost side of the air intake chamber 16 is connected to the drying chamber 17. The air intake fan 7 is installed inside the air intake chamber 16. The material trolley 8 is installed inside the drying chamber 17. The external rotor fan 9 is installed at the end of the protective shell 2. The evaporator 10, compressor 11, and condenser 12 are installed inside the protective shell 2. The condenser 12 is located at the air inlet of the air intake duct 3. The inlet and outlet of the compressor 11 are connected to the piping system of the condenser 12 and the evaporator 10 through copper pipes. The regenerator 13 is installed on the side wall of the protective shell 2 and is located at the air outlet of the return air duct 4. The controller 14 is installed on the side wall of the protective shell 2. The dehumidifying fan 5, air intake fan 7, external rotor fan 9, evaporator 10, compressor 11, condenser 12, regenerator 13 and controller 14 are electrically connected.

[0021] like Figure 5 As shown, a temperature sensor 18 and a humidity sensor 19 are installed in the drying chamber 17. The temperature sensor 18 and humidity sensor 19 are electrically connected to the controller 14. The controller 14 automatically adjusts the frequency of the compressor 11 and the speed of the fan according to the preset drying parameters. The temperature sensor 18 and humidity sensor 19 monitor the temperature and humidity data in the drying chamber 17 in real time and transmit the data to the controller 14. The controller 14 compares the actual data with the preset parameters. If the actual data exceeds the preset range, the controller 14 automatically adjusts the frequency of the compressor 11 and the speed of the fan to restore the temperature and humidity in the drying chamber 17 to a suitable range.

[0022] like Figure 3-5As shown, the drying chamber 1 is also equipped with an airflow equalization plate 20, which is installed at the connection between the air intake chamber 16 and the drying chamber 17. The material cart 8 located at the connection between the air intake chamber 16 and the drying chamber 17 is also equipped with an airflow equalization plate 20, which is used to make the airflow entering the drying chamber 17 more evenly distributed. When the airflow entering the drying chamber 17 from the air intake chamber 16 passes through the airflow equalization plate 20, the airflow equalization plate 20 disperses the airflow, making the airflow more evenly distributed in the drying chamber 17, fully contacting the material, avoiding excessive or insufficient airflow in local areas, ensuring uniform heating of the material, and improving the consistency of drying effect.

[0023] like Figure 3-5 As shown, the material trolley 8 includes a support frame 21, casters 22, and trays 23. The casters 22 are installed at the bottom of the support frame 21. The trays 23, used for placing fruits, vegetables, and medicinal materials, are placed at equal intervals on the support frame 21. The trays 23 have a perforated plate structure and are equipped with handles for easy handling. Materials are placed on the trays 23, and then the trays 23 are placed at equal intervals on the support frame 21. The casters 22 are used to move the material trolley into the drying chamber 17 for drying. After drying, the trays 23 can be easily removed using the handles. This design facilitates the handling and placement of materials. The perforated plate structure of the trays 23 promotes air circulation, allowing the materials to better contact with hot air and improving drying efficiency. The handles 23 facilitate the removal and replacement of the trays.

[0024] The drying chamber 1 is equipped with polyurethane insulation panels on the outside to reduce heat loss inside the drying chamber 1 and improve energy efficiency. The insulation panels wrap around the outside of the drying chamber to keep it warm, prevent heat from being transferred outward, and maintain the temperature stability inside the drying chamber, which is conducive to improving drying quality and effectively retaining the heat inside the drying chamber.

[0025] The inner walls of the air inlet duct 3 and the air return duct 4 are both equipped with a heat insulation layer. The heat insulation layer is made of heat-insulating rock wool, and the surface of the rock wool is bonded with moisture-proof aluminum foil, which can effectively reduce the heat exchange between the inside and outside of the duct and ensure the drying effect. The heat insulation layer is located on the inner wall of the air inlet duct and the air return duct, so that the heated air maintains a high temperature during the transportation process and the discharged hot and humid air remains stable during the transportation process.

[0026] A sealing strip is provided between the movable door 15 and the main body of the drying chamber 1, which can enhance the sealing performance of the movable door 15 and prevent heat and moisture leakage. When the movable door is closed, the sealing strip is squeezed and fills the gaps, ensuring the stability of the environment inside the drying chamber, improving drying efficiency and quality, and reducing energy waste.

[0027] Work process: Workers first evenly place the fruits, vegetables, and medicinal herbs to be dried on the trays 23 of the material trolley 8. The trays 23 have a perforated structure to facilitate air circulation. Using the casters 22, the material trolley 8 is easily moved into the drying chamber 17 of the drying room 1. The movable door 15 is closed, and the sealing strip between the movable door 15 and the main body of the drying room 1 is compressed to fill the gap, ensuring good airtightness of the drying room and preventing heat and moisture leakage. The controller 14 starts the device, and the external rotor fan 9 operates, introducing outside air into the protective shell 2. The air first passes through the evaporator 10, where it absorbs heat from the air, lowering the air temperature. The water vapor in the air liquefies upon contact with the cold air, achieving dehumidification. The compressor 11 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas, which is then delivered to the condenser 12. As the air passes through the condenser 12, it absorbs the heat released by the condenser, raising its temperature and becoming dry, hot air. The heated dry air enters the drying chamber 1 through the air inlet duct 3. The heat insulation layer on the inner wall of the air inlet duct 3 prevents heat loss during transportation. The hot air enters the air intake chamber 16 from the air inlet at the top of the side wall of the drying chamber 1. The air intake fan 7 accelerates the air flow, so that the hot air is evenly distributed in the air intake chamber 16. The hot air in the air intake chamber 16 enters the drying chamber 17 through the connection between the air intake chamber 16 and the drying chamber 17. When the airflow passes through the airflow equalization plate 20, it is dispersed and more evenly distributed in the drying chamber 17, making full contact with the fruits, vegetables and medicinal materials on the material cart 8, removing the surface moisture and achieving the drying effect. During the drying process, the dehumidifying fan 5 is started to draw the hot and humid air in the drying room 1 out through the return air vent. Since the inner wall of the return air duct 4 has a heat insulation layer composed of heat-insulating rock wool and moisture-proof aluminum foil, it can effectively reduce heat loss and allow the hot and humid air to be stably transported through the return air duct 4 to the protective shell 2. The regenerator 13 is installed at the air outlet of the return air duct 4 to recover and utilize the heat in the return air and reduce energy consumption.

[0028] Temperature sensor 18 and humidity sensor 19 inside drying chamber 17 monitor the temperature and humidity inside drying chamber 17 in real time and feed the data back to controller 14. Controller 14 compares the actual data with preset parameters. If the actual data exceeds the preset range, controller 14 automatically adjusts the frequency of compressor 11 and the speed of fan to restore the temperature and humidity inside drying chamber 17 to a suitable range. When the temperature and humidity inside drying chamber 17 reach the preset drying standard, controller 14 controls the dehumidifier fan 5, air inlet fan 7, external rotor fan 9, compressor 11 and other equipment to stop running. The operator removes the tray 23 from the material trolley 8 using the handle on the tray 23 and moves the material trolley 8 out of drying room 1 using casters 22.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
