[0002] Bio-based products mainly refer to lignocellulosic agricultural and forestry wastes such as straw other than grain, such as corn, sugarcane or cellulose. Laminar flow is a flow state of fluid. Bio-based materials are usually transported in a laminar flow manner. During the processing of bio-based materials, the raw materials need to be dried and dried for subsequent processing.

[0003] However, most of the existing drying devices use a hot air blower to dry the materials. During the drying process, the bio-based materials are often in a piled state, which makes it difficult for the bio-based materials in the inner layer of the pile to contact with the high-temperature air and be dried, reducing the material drying efficiency of the device. In addition, the generated hot air can only be delivered in one direction, resulting in uneven distribution, affecting the drying effect. Therefore, a laminar flow drying device for bio-based materials is proposed to address the above problems. Utility Model Content

[0026] Furthermore, the first flap 3 is fixedly connected to the drive shaft 2, and the first flap 3 is arranged in six groups. The six groups of first flaps 3 are evenly distributed along the outer wall of the drive shaft 2, and the second flap 5 is in an arc shape. The second flap 5 is fixedly connected to the connecting rod 4, and the drive shaft 2 is rotated by the motor on the outside of the fixed plate 6, so that the second flap 5 in an arc shape fixedly connected to the end of the connecting rod 4 is rotated along the inner wall of the drying body 1 for drying, which can ensure that the material is evenly turned and mixed during the drying process, thereby avoiding material agglomeration or adhesion, and improving the drying efficiency. The material is continuously thrown up and scattered inside the drying body 1, increasing the contact area between the material and the hot air flowing through, and then the first flap 3 is rotated and turned by the second flap 5 through the driving shaft 2, so that the material is more comprehensively turned and stirred inside the drying body 1. The coordinated use of the first flap 3 and the second flap 5 can ensure that the material is more evenly heated and ventilated during the drying process, thereby improving the drying effect.

[0027] Furthermore, the second through hole 10 forms a circulation structure with the hot air blower 7 through the first through hole 8 and the installation cavity 9. The second through holes 10 are evenly distributed along the inside of the installation cavity 9. The hot air blower 7 is heated by an electric heating element. There is a fan or blower inside the hot air blower 7. When the fan is started, it will inhale cold air from the surrounding environment. The inhaled cold air is then heated to the required temperature through the heat source. This can be achieved by guiding the air through the heating element or burner. The heated air is then sent out through the air outlet of the hot air blower 7. This hot air can be guided into the drying chamber of the laminar flow drying device for bio-based materials for drying the materials. This belongs to the prior art and will not be elaborated in detail.

[0028] The set hot air is sent into the interior of the installation cavity 9 through the first through hole 8, and then can be evenly distributed to each position inside the drying body 1 by setting six groups of second through holes 10, avoiding the problem that the hot air is too concentrated in some areas and insufficient in other areas, thereby improving the uniformity and consistency of drying. The hot air can evenly cover each position, and the material can get sufficient heat in each area, thereby accelerating the drying process. Embodiment 2

The material is constantly thrown up and scattered inside the drying body 1, increasing the contact area between the material and the hot air flowing through. Then the first flap 3 is rotated and turned by the second flap 5 through the driving shaft 2 to rotate and turn the internal center, so that the material is more comprehensively turned and stirred inside the drying body 1.
