The humidification assembly 3 includes a second rack 301, inside which a support frame 302 is installed, and a conveying pipe 303 is fixedly connected inside the support frame 302. A spray pipe 304 is fixedly connected inside the conveying pipe 303, and the spray pipe 304 is provided with a rod. The moisture content detection assembly 4 includes a third rack 401, and the bottom of the third rack 401 is equipped with... Equipped with an infrared moisture content sensor 402, a PLC controller 403 is fixedly connected to the side of the third rack 401. It adopts a hot air drying method, and the drying process of straw is achieved by adjusting the hot air temperature and air volume.

The spraying method can evenly spray water on the surface of the straw to ensure that the moisture content of each part of the straw is consistent. Spray humidification can quickly increase the moisture content of the straw in a short time to meet the requirements of subsequent processing or treatment.

[0030] Two rectangular troughs 202 are provided, and two hot air fans 203 are provided. A liquid tank 305 is fixedly connected to the top of the second trough 301. A connecting pipe 308 is fixedly connected to the side of the liquid tank 305. A liquid pump 307 is installed on the side of the connecting pipe 308.

An operation interface 404 is provided on the side of the PLC controller 403. The operation interface 404 protects the display screen, switches, and operation keys. An infrared moisture sensor 402 is used to detect the straw in real time. The moisture content of the straw is measured and transmitted to the PLC controller 403. The straw pretreatment device with moisture content regulation can accurately control the moisture content of the straw, improve the pretreatment effect, and achieve efficient and stable moisture content regulation through automated control, thereby improving the efficiency of subsequent processing and product quality. The device has a simple structure and is easy to operate, making it suitable for large-scale straw pretreatment. Using the PLC controller 403 and the operation interface 404, it can automatically adjust the working status of the drying unit and the humidification unit according to the feedback signal from the moisture content detection unit, ensuring that the moisture content of the straw is stable within the set range and improving the efficiency of moisture content monitoring.
