The other end of the mixed flow air inlet pipe 8 is arranged on the mixed flow drying hood. The mixed flow air inlet pipe 8 is fixedly connected to the mixed flow drying hood by welding or the like. After the hot air enters the cross flow layer air inlet hood 6, a part of the air directly enters the cross flow drying layer 4 through the air inlet 16, and the other part of the hot air is extracted by the hot air blower 7 through the mixed flow air inlet pipe 8 and sent to the mixed flow layer air inlet hood 9, and then enters the mixed flow drying layer 2 through the air inlet 2 5. An angular box 12 is arranged on the side wall of the mixed flow drying layer 2, and there are 24 angular boxes 12. The angular boxes 12 are fixedly connected to the side wall of the mixed flow drying layer 2 by welding or the like. The angular boxes 12 are connected to the air inlet 2 5 by arranging a pipeline or the like, so that hot air can enter the angular box 12 through the air inlet 2 5, and then be emitted into the mixed flow drying layer 2 through the opening at the bottom of the angular box 12, so as to dry the grains entering the mixed flow drying layer 2. A triangular guide plate 13 is arranged in the grain separation layer 3, and the triangular guide plate 13 is fixedly connected to the side wall of the grain separation layer 3 by arranging welding or the like. When the grains flow downward from the mixed flow drying layer 2 into the grain separation layer 3, they pass through the triangular guide plate 13. After reaching the tip, the grains are dispersed into the cross-flow drying layer 4. A fixed bracket 15 is provided on the inner wall of the cross-flow drying layer 4. The fixed bracket 15 is fixedly connected to the side wall of the cross-flow drying layer 4 by welding or the like. A mesh 14 is provided on the fixed bracket 15.

While the mixed flow drying layer 2 heats the grains, because the mixed flow drying layer 2 is provided with a cross-flow dehumidification fan 11, the hot air enters the cross-flow drying layer 4 under the action of the negative pressure in the cross-flow drying layer 4, and the humid hot air in the mixed flow drying layer 2 is combined with the hot air in the cross-flow drying layer 4 to heat the grains again. Compared with the convective heating of dry air and grains, the humid hot air has an increased thermal conductivity, thereby further improving the drying efficiency, drying uniformity and thermal energy utilization rate.

[0022] Working principle: When in use, the mixed flow drying layer is set at the bottom of the grain slow recovery machine, close to the cross-flow drying layer 4, the grains in the slow recovery machine enter the mixed flow drying layer 2, the grains flow through the mixed flow drying layer 2 and enter the grain distribution layer 3, and the grains are guided by the triangular guide plate 13, so that the grains fall into the gaps between the meshes 14 of the cross-flow drying layer 4. At the same time, after the hot air enters the cross-flow layer air inlet hood 6, part of the wind directly enters the cross-flow drying layer 4 through the air inlet 16 to carry out cross-flow drying of the grains, and the other part of the hot air is extracted by the hot air blower 7 and sent to the mixed flow layer air inlet hood 9 through the mixed flow air inlet pipe 8, and then enters the angular box 12 through the air inlet 2 5, so as to be distributed to the mixed flow drying layer 2 to carry out mixed flow drying of the grains, and the cross-flow dehumidification fan 11 discharges the distributed moisture.
