Optionally, the pipe orifice of the first branch pipe 322 may be disposed at a position close to the conveying line 600, so that the hot air entering the first branch pipe 322 is waste heat after heat exchange with the product, thereby further improving the utilization rate of the hot air while ensuring the dehumidification effect of the product.

Of course, in practical application, the first branch pipe 322 may also directly introduce the hot air blown from the second blowing pipe 350, so as to realize the function of supplying heat to a plurality of drying chambers simultaneously by using one burner 410.

Similarly, referring to fig. 5 to 7, in order to ensure the drying effect of the product in the first drying chamber 210 and reduce the waste of hot air, the nozzle of the second branch pipe 432 is located between the first blowing pipe 340 and the conveying line 600.

The second branch pipe 432 guides hot air in the first sub-drying chamber 211 into the second main pipe 431, the first air blowing pipe 340 blows hot air in the first air inlet pipe 320 to the conveying line 600, and the pipe orifice of the second branch pipe 432 is arranged between the first air blowing pipe 340 and the conveying line 600, so that the hot air blown out by the first air blowing pipe 340 enters the second branch pipe 432 after being blown to dehumidify a product, and waste heat in the first drying chamber 210 is guided into the combustor 410 on the premise of ensuring the drying and dehumidifying effects of the product, thereby realizing hot air utilization.

Optionally, the pipe orifice of the second branch pipe 432 may be disposed at a position close to the conveying line 600, so that the hot air entering the second branch pipe 432 is waste heat after heat exchange with the product, thereby further improving the utilization rate of the hot air while ensuring the dehumidification effect of the product.

In an embodiment of the present invention, referring to fig. 1 to 4, the first main pipe 321 is disposed below the conveyor line 600 and extends along an extending direction of the conveyor line 600.

It can be understood that the conveying line 600 is disposed on the rack 100, and the first main pipe 321 is disposed below the conveying line 600, so that the first main pipe 321 is disposed below the rack 100 and is disposed along the extending direction of the conveying line 600, so that the space utilization rate is increased, and the compactness of the overall structure layout is improved. On this basis, first branch pipe 322 is the extension setting from top to bottom, when reducing the pipeline route, guarantees structural stability.
