[0029] The upper and lower parts of the connection surface between the equipment room 2 and the drying room 1 are respectively provided with a return air vent 22 and a drying air vent 21. A heat exchange coil 7 is inclinedly arranged below the return air vent 22 in the equipment room 2. The heat exchange coil 7 divides the equipment room 2 into upper and lower parts. At least one fan 8 is arranged in the lower part of the equipment room 2. A heating coil 6 is arranged between the air outlet of the fan 8 and the drying air vent 21.

[0030] The inlet end of the heating coil 6 is connected to a hot water pipe 62. The hot water pipe 62 extends out of the equipment room 2 and is connected to a hot water inlet pipe 61. The hot water inlet pipe 61 is connected to the outlet end of an external hot water supply device. The outlet end of the heating coil 6 is connected to the inlet end of the heat exchange coil 7 through a hot water outlet pipe 63. The outlet end of the heat exchange coil 7 is connected to a drain pipe 71. The drain pipe 71 extends out of the equipment room 2 and is connected to a drain pipe 72. The drain pipe 72 is connected to an external waste hot water recovery device.

[0031] The roof 4 is equipped with an exhaust assembly 5 for discharging moisture from the drying process, and the drying room 1 has a material door 3 on the side away from the equipment room 2.

[0032] The roof 4 is provided with a double-layer guide rail 41 along its length. A fixed top plate 42 is installed at the bottom of the double-layer guide rail 41 above the equipment room 2. A sliding top plate 42 is slidably arranged on the lower guide rail of the double-layer guide rail 41. The exhaust assembly 5 is slidably arranged on the upper guide rail of the double-layer guide rail 41.

[0033] The exhaust assembly 5 includes an exhaust sliding frame 51 slidably disposed on the upper guide rail of the double-layer guide rail 41. A set of rotating shafts 56 are rotatably connected to the exhaust sliding frame 51 along its length. A set of opening and closing plates 57 are fixedly connected to each of the two rotating shafts 56. A cylinder 52 is installed on the exhaust sliding frame 51 at one end of the rotating shaft 56. The output end of the cylinder 52 is connected to the bottom surface of the connecting rod 54 through a first guide rod 53. The two ends of the connecting rod 54 are respectively hinged to second guide rods 55. The two second guide rods 55 are respectively fixedly connected to the rotating shafts 56.

[0034] The exhaust sliding frame 51 is equipped with several seated bearings 58, and the rotating shaft 56 is rotatably mounted on the seated bearings 58.

[0035] The drying room 1 and the equipment room 2 are equipped with several temperature sensors 10, the drying room 1 is equipped with a humidity sensor, the equipment room 2 is equipped with an electrical cabinet 9 on its outer wall, the temperature sensors and humidity sensors are electrically connected to the electrical cabinet 9, and the electrical cabinet 9 is electrically connected to a fan 8.

[0036] The equipment room 2 has an openable air vent located at one end of the air inlet of the fan 8. This air vent opens to supply air to the fan when drying begins, opens again to supply air to the fan after the exhaust assembly exhausts air, and closes after the air in the equipment room has been circulated.

[0037] The hot water pipe 62 is connected to a hot water pump 64 and a first hand valve, and a second hand valve is connected in parallel to the hot water pipe 62 at the hot water pump 64.

[0039] The working principle of this invention is as follows: In use, open the material door and place the bamboo mat to be dried inside the drying chamber. Then close the material door. (Alternatively, the sliding top plate and exhaust assembly can be slid above the fixed top plate, and then the bamboo mat to be dried can be lowered into the drying chamber from above the roof using a gantry crane.) After the bamboo mat is placed, hot water (or other heating fluid) is introduced into the heating coil through the hot water inlet pipe and hot water conduit. Then, a fan blows air through the heating coil, turning the blown air into hot air. This hot air is then blown into the drying chamber through the drying air vents. The bamboo mats are heated and dried. The hot air returns to the upper part of the equipment room through the return air vent. During this process, the residual hot water discharged from the heating coil enters the heat exchange coil and heats the return air. The residual hot air returns to the air inlet of the fan to form a circulation. This makes full use of the residual heat in the drying room and the residual heat from the water discharged from the heating coil. After the humidity in the equipment room reaches a certain level, the opening and closing plate is opened by the cylinder of the exhaust component, and the moisture is discharged from the exhaust component above. The drying continues until the bamboo mat reaches the standard for drying, and then the bamboo mat is removed.
