[0002] Starch is a polysaccharide and can be regarded as a polymer of glucose. Plants store energy by producing starch. In addition to being eaten directly, starch can also be used to make dextrin, maltose, glucose, alcohol, etc. It is also used to prepare printing paste, sizing of textiles, gluing of paper, pressing of pharmaceutical tablets, etc. Starch is generally extracted from starch-containing substances such as corn, sweet potato, wild acorn and kudzu root.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Example 1

[0032] See Figures 1 to 8In an embodiment of the present invention, a drying device for starch production includes a fixed base 1, a support plate 2 is fixedly installed on the rear side of the upper end of the fixed base 1, and the support plate 2 is a trapezoidal plate structure. A fixed bevel gear 14 is fixedly installed on the support plate 2, and a power shaft is rotatably installed at the center position of the fixed bevel gear 14. A rotating frame 5 is fixedly installed at the front end of the power shaft, and a clearance groove 32 is symmetrically provided on the rotating frame 5. A rotating shaft 30 is rotatably installed on the clearance groove 32, and a rotating bevel gear 31 that meshes with the fixed bevel gear 14 is installed on the rotating shaft 30, so that when the power shaft drives the rotating frame 5 to rotate, the rotating bevel gear 31 will mesh with the fixed bevel gear 14, and finally the rotating shaft 30 rotates. One end of the outer side of one rotating shaft 30 is connected to a rotating shaft arranged between the rotating frame 5 through a pulley group a24. The drying box 4 is provided with a rotating shaft 30, so that the rotating shaft 30 drives the drying box 4 to rotate synchronously while rotating. The outer end of the other rotating shaft 30 is connected to the drying shaft 28 rotatably arranged inside the drying box 4 through a pulley group b29, so that the rotating shaft 30 also drives the drying shaft 28 located inside the drying box 4 to rotate synchronously while rotating. The outer end of the rotating frame 5 is provided with a knocking mechanism for knocking the outer wall of the drying box 4, thereby knocking the agglomerated starch attached to the inner wall of the drying box 4 when the drying box 4 rotates, further improving the drying quality. The fixed base 1 is provided with a hot air mechanism for inputting hot air into the drying box 4, thereby achieving the purpose of rapid drying of the starch. The support plate 2 is provided with a power mechanism for driving the power shaft to rotate back and forth, thereby further improving the drying quality of the starch.

[0033] In one case of this embodiment, the power mechanism includes a power frame 11 fixed on the support plate 2, and a power motor 10 is fixedly installed on the power frame 11. The output end of the power motor 10 is connected to the crank frame 9, and a movable rack 12 is hinged on the crank frame 9. The outer side of the movable rack 12 is engaged with a reciprocating gear 13 fixed to the end of the power shaft. Specifically, when working, the power motor 10 drives the crank frame 9 to rotate, and then the movable rack 12 moves back and forth along the outer side of the reciprocating gear 13, and then the reciprocating gear 13 performs clockwise and counterclockwise reciprocating motion, and finally realizes the synchronous movement of the power shaft.

[0034] In one case of this embodiment, a limit frame 34 is further provided between the reciprocating gear 13 and the movable rack 12. The limit frame 34 is rotatably provided on the power shaft. By providing the limit frame 34, the movable rack 12 is always engaged with the reciprocating gear 13 when moving, thereby further improving the movement reliability of the power mechanism.

[0035] In one case of this embodiment, the hot air mechanism includes a hot air box 7 fixed on a fixed base 1, the hot air box 7 is connected to a hot air pipe 6, the hot air pipe 6 is connected to an air guide cylinder 19 fixed on a rotating frame 5, a drying shaft 28 is passed through the inside of the air guide cylinder 19, and an air guide hole 33 is provided on the drying shaft 28 located inside the air guide cylinder 19. The interior of the drying shaft 28 is a hollow structure. Specifically, hot air is generated inside the hot air box 7, and then enters the inside of the air guide cylinder 19 with the cooperation of the hot air pipe 6, and then the hot air enters the inside of the drying shaft 28 through the air guide hole 33.

[0036] In one case of this embodiment, a plurality of drying blades 26 are installed on the outside of a drying shaft 28 located inside the drying box 4. The drying blades 26 are provided with a plurality of drying holes 27. The drying blades 26 are connected to the interior of the drying shaft 28. Specifically, the hot air entering the interior of the drying shaft 28 is discharged through the drying holes 27 on the drying blades 26, and then cooperates with the rotating drying blades 26 to achieve the purpose of rapid drying of the starch inside the drying box 4.

[0037] In one case of this embodiment, the drying box 4 is provided with an inlet and outlet hopper 18, which makes it convenient for the staff to introduce the starch to be dried into the drying box 4 and take out the dried starch.

[0038] In one case of this embodiment, a reinforcing rib plate 8 is further installed between the support plate 2 and the fixed base 1, thereby improving the mechanical connection performance between the support plate 2 and the fixed base 1.

[0039] In one case of this embodiment, the knocking mechanism includes a fixed frame 3 installed on a rotating frame 5, a transmission shaft 22 is rotatably installed on the fixed frame 3, a knocking shaft 17 is installed on the transmission shaft 22 through a telescopic part, a knocking pad 15 is installed on the end of the knocking shaft 17, and a guide plate 23 arranged between the fixed frames 3 is connected on the knocking shaft 17. Specifically, during operation, the transmission shaft 22 rotates, and then with the cooperation of the telescopic part, the knocking shaft 17 drives the knocking pad 15 to knock on the outer wall of the drying box 4 in a rotating state, thereby causing the starch attached to the inner wall of the drying box 4 to fall, further improving the drying quality.

[0040] In one case of this embodiment, the telescopic part includes a telescopic crank 20 arranged on a transmission shaft 22, a crank sleeve 21 is hingedly mounted on the telescopic crank 20, a telescopic rod 16 is installed on the crank sleeve 21, and the telescopic rod 16 is hingedly connected to the knocking shaft 17. Specifically, the transmission shaft 22 rotates to rotate the telescopic crank 20, and then the crank sleeve 21 drives the telescopic rod 16 to move synchronously, and then the knocking shaft 17, under the cooperation of the guide limit of the guide plate 23, achieves the purpose of knocking on the drying box 4.

[0041] Example 2

[0042] In another embodiment of the present invention, this embodiment differs from the above embodiment in that one end of the transmission shaft 22 passes through the fixed frame 3 and is coaxially connected to the drying box 4 through the pulley group c25. Specifically, the pulley group c25 is set so that the rotating shaft 30 can drive the transmission shaft 22 to rotate, ultimately ensuring that one power source can drive multiple technical components to rotate, further reducing the operating cost of the device.

[0043] The working principle of the present invention is as follows: when working, the starch to be dried is first placed inside the drying box 4 through the inlet and outlet hopper 18, and then the hot air box 7 and the power motor 10 are started, so that the drying box 4 revolves and rotates at the same time. At the same time, the drying shaft 28 located inside the drying box 4 also sprays hot air while rotating, thereby achieving the purpose of rapid drying of the starch inside the drying box 4. At the same time, the knocking pad 15 also periodically knocks the outer wall of the drying box 4 to prevent the starch from adhering to the inner wall of the drying box 4, thereby further improving the drying quality.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
