[0016] See also Figure 1 , Figure 2 and Figure 3, a mushroom drying system with continuous temperature rise is provided, which can be implemented in the following manner: comprising a drying box 10 and a drying cart 20, wherein the interior of the drying box 10 is divided into a preliminary drying section 11 with a temperature maintained at 35-40°C, a uniform drying section 12 with a temperature maintained at 40-50°C, and a complete drying section 13 with a temperature maintained at 50-60°C; a plurality of trays 21 for drying mushrooms are arranged on the drying cart 20 in an overlapping manner. The continuous temperature rise drying method is adopted, with the starting temperature being 35°C and the maximum temperature not exceeding 60°C, and the continuous temperature rise method is adopted, so as to avoid the mushrooms from becoming black and burnt.
[0017] In the mushroom drying system described in the present application, a plurality of round holes 21A for inserting mushroom stems are evenly distributed on the tray 21. When loading, place the mushroom caps upward and the stems downward into the round holes 21A, and place them evenly to avoid overlapping or stacking to avoid damage to the mushrooms.
[0018] In the mushroom drying system described in the present application, a guide rail 30 is provided at the bottom of the drying box 10 for facilitating the movement of the drying cart 20, so as to facilitate the corresponding movement and movement of the drying cart 20.
[0019] In the mushroom drying system described in the present application; the preliminary drying section 11, the uniform drying section 12 and the complete drying section 13 are separated by movable doors, and multiple groups of spray nozzles 14 are installed on the side of each drying section, which can be used to spray trays 21 at different positions on the drying cart 20.
[0020] In the mushroom drying system described in the present application, a temperature detection unit and a heating unit are provided in each drying section. The temperature detection unit is used to detect the current temperature in the drying section and transmit it to the PLC control system 50. The heating unit can be an electric heating unit, and the PLC control system 50 can control the temperature increase operation.
[0021] The mushroom drying system described in the present application also includes a cooling section 40, which is located at the end surface of the complete drying section 13 and is used to cool the dried mushrooms transported out of the complete drying section 13. The cooling operation is performed in the cooling section 40 to cool the mushrooms to room temperature, and then enter the packaging stage.
