[0022] This utility model discloses a drying device for wheat variety selection. The inner wall of the dehumidification chamber 2 is provided with waterproof aluminum foil 15. The dehumidification chamber 2 is provided with two silicone dehumidification layers 16, which are coarse-pore silicone particles and fine-pore silicone particles, respectively. An airflow channel 17 is provided between the two silicone dehumidification layers 16 to facilitate dehumidification of the air.
[0023] This utility model discloses a wheat variety breeding and drying device. The inner wall of the heating chamber 3 is provided with an aluminum silicate heat insulation layer 18.

The surface of each PTC ceramic heating element 19 is provided with a honeycomb stainless steel protective mesh 20 to facilitate heating of the air.
[0024] This utility model discloses a wheat variety breeding and drying device.

[0025] This utility model discloses a wheat variety breeding and drying device. Each of the two guide rails 4 is provided with a limiting groove 23 on one side, and each of the multiple fixing blocks is threaded with a locking bolt 24 on one side. The multiple locking bolts 24 are slidably connected to the two limiting grooves 23 respectively, so as to facilitate the adjustment of the distance between the partitions 6.
[0026] This utility model discloses a drying device for wheat variety selection. Multiple drying chambers 7 are each fixedly equipped with a temperature and humidity sensor 25 and a moisture sensor 26. A humidity sensor is fixedly installed at the bottom of the dehumidification chamber 2. A thermocouple temperature sensor 28 is fixedly installed inside the heating chamber 3.

After starting the device, the circulating fan 12 starts working, and the hot and humid air in the drying chamber 7 is drawn to the dehumidification chamber 2. The hot and humid air is dehumidified by the gradient adsorption of the coarse-pore silica gel dehumidification layer 16 and the fine-pore silica gel dehumidification layer 16 in the dehumidification chamber 2, and then enters the heating chamber 3. It is heated to the set temperature by the PTC ceramic heating element 19, and the heated dry hot air is delivered to the corresponding drying chamber 7 through the air guide pipe 13. At the same time, the vibration motor... 21 drives the eccentric wheel 22 to rotate, which, in conjunction with the bottom spring 9, causes the breathable material carrier plate 10 to produce slight flexible vibration, preventing seed clumping and ensuring uniform contact between the seeds and the hot air. Temperature and humidity sensors 25 and moisture sensors 26 monitor the internal state of each drying chamber 7 in real time, the humidity sensor monitors the dehumidification effect of the dehumidification chamber 2, and thermocouple temperature sensor 28 controls the temperature of the heating chamber 3. All data are fed back to the controller 30, which dynamically adjusts the power of the PTC ceramic heating element 19, the opening of the solenoid valve 14, and the working status of the vibration motor 21. When the seed moisture in a certain drying chamber 7 reaches the preset threshold, the controller 30 closes the solenoid valve 14 of the corresponding air duct 13 and the vibration motor 21 associated with that chamber, stopping the drying process. After all drying is completed, the device is turned off, and the seeds can be removed.
