Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] AsFigures 1-6 As shown in the figure, the utility model provides a technical solution: a hot air continuous drying device for dehydrating and processing dehydrated vegetables, which includes a drying box body 1. One end of the drying box body 1 is rotatably connected with a sealed box door 2. The top end of the drying box body 1 is fixedly connected with a hot air blower 4, and the bottom end of the hot air blower 4 is fixedly connected with an air guiding and sealing pipe 5. The bottom end of the air guiding and sealing pipe 5 penetrates through the top end of the drying box body 1 and extends into its interior. Two pairs of air blowing pipes 6 are fixedly connected to the outer wall of the air guiding and sealing pipe 5. A collecting ring basin 7 is arranged inside the drying box body 1, and a pair of connecting plates 11 are fixedly connected between the outer wall of the collecting ring basin 7 and the inner wall of the drying box body 1. An eccentric rotation mechanism 8, a squeezing and vibrating material mechanism 9 and a heat conducting side blowing mechanism 10 are respectively arranged inside the drying box body 1. A rectangular through opening is drilled on the outer wall of the sealed box door 2, and a transparent observation plate 3 is fixedly connected to the inner wall of the rectangular through opening.

[0026] During the use of this solution, the hot air blower 4 blows hot air downward through the air guiding and sealing pipe 5 and two pairs of air blowing pipes 6, so as to dehydrate and dry the vegetables inside the drying box body 1. And the water droplets on the surface of the washed vegetables fall downward under the blowing action and can be collected by the collecting ring basin 7. The transparent observation plate 3 can facilitate the staff to observe the dehydration situation of the vegetables inside the drying box body 1 in real time.

[0027] As Figures 1-3 shown in the figure, the eccentric rotation mechanism 8 includes a rotation motor 801 fixedly connected to the inner bottom end of the drying box body 1. The output end of the rotation motor 801 is fixedly connected with an adapter radiation frame 802, and a circular ring plate 803 is fixedly connected to the outer wall of the adapter radiation frame 802. A plurality of uniformly distributed air permeable through cylinders 804 are embedded and connected to the top end of the circular ring plate 803. The circular ring plate 803 is located above the collecting ring basin 7, and the inner and outer diameters of the collecting ring basin 7 are both matched with the inner and outer diameters of the circular ring plate 803. The squeezing and vibrating material mechanism 9 includes a plurality of filter mesh plates 901. Elastic annular membranes 902 are fixedly connected to the outer walls of the plurality of filter mesh plates 901, and the outer walls of the elastic annular membranes 902 are fixedly connected to the inner walls of the air permeable through cylinders 804. Circular rods 903 are fixedly connected to the bottom ends of the plurality of filter mesh plates 901, and movable hemispheres 904 are fixedly connected to the bottom ends of the circular rods 903. A plurality of uniformly distributed arc end strips 905 are fixedly connected to the inner bottom end of the collecting ring basin 7, and the inner bottom end of the collecting ring basin 7 is in contact with the outer wall of the movable hemisphere 904.

[0028] During the use of this solution, the rotating motor 801 drives the connecting radiation frame 802 to rotate, the connecting radiation frame 802 drives the circular ring plate 803 to rotate, driving multiple air-permeable cylinders 804 and the filter screen plate 901 to rotate synchronously. The vegetables on the top of the corresponding filter screen plate 901 rotate, and under the centrifugal force, the water droplets on the surface of the washed vegetables fall off. At the same time, multiple round rods 903 and movable hemispheres 904 rotate along the inner bottom end of the collection ring basin 7, and during the rotation process, they repeatedly rotate with multiple arc-end long strips 905. Affected by the contact extrusion and separation, the movable hemisphere 904 repeatedly moves upward away from and downward contacts the inner bottom end of the collection ring basin 7, prompting the vegetables on the top of the filter screen plate 901 to move up and down repeatedly, so that the water droplets on the surface of the washed vegetables can fall off fully and are not likely to remain. And the moisture inside the corresponding vegetables is more fully and comprehensively dehydrated and dried under the action of the up-and-down movement, the moisture volatilizes faster, effectively enhancing the dehydration and drying effect.

[0029] As Figure 1 , Figure 4 and Figure 5 shown, the heat-conducting side-blowing mechanism 10 includes a pair of heat-conducting elbow pipes 1001 both fixedly connected to the inner wall of the drying box body 1. A pair of heat-conducting elbow pipes 1001 are both embedded and connected to the connecting plate 11. The close ends of a pair of heat-conducting elbow pipes 1001 are both fixedly connected with heat-conducting straight pipes 1002. The output end of the rotating motor 801 is sleeved with a turntable 1003, and two pairs of extrusion convex rods 1004 are fixedly connected to the outer wall of the turntable 1003. The inner wall of the drying box body 1 is fixedly connected with a U-shaped plate 1006, and a T-shaped rod 1007 is arranged inside the U-shaped plate 1006. A through hole is drilled in the inner wall of the U-shaped plate 1006, and one end of the T-shaped rod 1007 passes through the through hole and is fixedly connected with an arc-shaped plate 1005. Springs 1008 are sleeved on the outer walls of a pair of T-shaped rods 1007, and the two ends of the springs 1008 are respectively fixedly connected to the opposite sides of the arc-shaped plate 1005 and the U-shaped plate 1006. The outer walls of a pair of arc-shaped plates 1005 are respectively in contact with the outer walls of a pair of extrusion convex rods 1004. The ends of a pair of arc-shaped plates 1005 close to the T-shaped rod 1007 are fixedly connected with T-shaped extrusion plates 1009, and the outer wall of the T-shaped extrusion plate 1009 is slidably connected to the inner wall of the heat-conducting straight pipe 1002. Heat-conducting layers are provided on the surfaces of a pair of heat-conducting elbow pipes 1001 and the heat-conducting straight pipes 1002, and the heat-conducting elbow pipes 1001 correspond to the air-permeable cylinders 804.

[0030] During the use of this solution, when the hot air blows downward, most of the released heat accumulates on the inner bottom end and the inner wall of the drying box body 1. The heat conduction elbow pipe 1001 and the heat conduction straight pipe 1002 conduct the heat to their interiors through the heat conduction layer to heat the air inside. At the same time, the rotating motor 801 drives the two pairs of extrusion convex rods 1004 to rotate through the turntable 1003. When the two pairs of extrusion convex rods 1004 rotate, they repeatedly extrude the T-shaped extrusion plate 1009 to move reciprocally with the assistance of the T-shaped rod 1007 and the spring 1008, extruding the hot air inside the heat conduction elbow pipe 1001 and the heat conduction straight pipe 1002 to blow out laterally towards the vegetables inside the air permeable cylinder 804. Thus, it realizes blowing from the side using the released heat resources to assist in the dehydration and drying process of the vegetables, reducing the waste of heat resources, facilitating the continuous drying process of the vegetables, and enhancing the drying effect.

[0031] Working principle: First, open the sealed box door 2, and sequentially place multiple washed vegetables onto the filter plates 901 inside the multiple air permeable cylinders 804. Then, the hot air blower 4 blows hot air downward through the air guiding and sealing pipe 5 and the two pairs of air blowing pipes 6. At the same time, the rotating motor 801 drives the circular ring plate 803 to rotate through the connecting radiation frame 802, driving the multiple air permeable cylinders 804, the filter plates 901, and the vegetables to rotate synchronously, causing the water droplets on the surfaces of the washed vegetables to fall under the action of centrifugal force. And the centrifugal rotation can also drive the multiple vegetables to evenly receive the blowing of the hot air. Correspondingly, when the multiple filter plates 901 rotate, they also drive the multiple round rods 903 and the movable hemispheres 904 to rotate along the inner bottom end of the collection ring basin 7. During the rotation, they repeatedly rotate with the multiple arc-end long strips 905. Affected by the contact extrusion and separation with them, the movable hemispheres 904 move upward away from and downward contact with the inner bottom end of the collection ring basin 7 repeatedly under the elastic action of the elastic annular film 902, causing the vegetables on the top ends of the filter plates 901 to move up and down repeatedly, enabling the water droplets on the surfaces of the washed vegetables to fall fully. At the same time, the moisture inside the vegetables in the moving state is dried more fully and comprehensively. During the process of the hot air blowing downward, most of the released heat accumulates on the inner bottom end and the inner wall of the drying box body 1. The heat conduction elbow pipe 1001 and the heat conduction straight pipe 1002 conduct the heat to their interiors through the heat conduction layer to heat the air inside. At the same time, the rotating motor 801 drives the two pairs of extrusion convex rods 1004 to rotate through the turntable 1003. When the two pairs of extrusion convex rods 1004 rotate, they repeatedly extrude the T-shaped extrusion plate 1009 to move reciprocally with the assistance of the T-shaped rod 1007 and the spring 1008, extruding the hot air inside the heat conduction elbow pipe 1001 and the heat conduction straight pipe 1002 to blow out laterally towards the vegetables inside the air permeable cylinder 804. Thus, it realizes blowing from the side using the released heat resources to assist in the dehydration and drying process of the vegetables, and realizes the continuous drying process of the vegetables.
