[0023] Example Please refer to Figure 1-Figure 4 The present embodiment provides a combined sprout sorting and drying device, including a sorting mechanism and a drying mechanism. The drying mechanism includes a drying box 1, and at least one pulley conveying mechanism 2 is provided in the drying box 1. The pulley conveying mechanism 2 is folded and tilted in the drying box 1 from top to bottom. A feed port 4 is provided at the top of the drying box 1, and the feed port 4 is connected to the feed end of the pulley conveying mechanism 2 located at the top. The sorting mechanism includes an air separation component and a material receiving component. The air separation component includes a hot air source 5, a conveying pipe 6 and an air separation plate 7. The two ends of the conveying pipe 6 are respectively connected to the outlet of the hot air source 5 and the inlet of the air separation plate 7. The air separation plate 7 faces the bottom of the pulley conveying mechanism 2 at the bottom and is parallel to the conveyor belt 3 of the pulley conveying mechanism 2 at the bottom. The material receiving component includes a material receiving part located above the pulley conveying mechanism 2 at the bottom, one end of the material receiving part extends out of the drying box 1, and a screening channel 12 is formed between the material receiving part and the drying box 1. The gas discharged from the gas distributor 7 can blow up the unqualified sprouts on the pulley conveyor mechanism 2 at the bottom and drop them into the screening channel 12. A plurality of air holes 9 are evenly spaced on the conveyor belt 3 of any pulley conveyor mechanism 2; an air outlet 10 is provided on the top of the drying box 1.
[0024] The sorting mechanism is primarily used to sort the shredded sprouts. During the shredding process, a large amount of waste, such as debris (hereinafter referred to as unqualified sprouts), is present, necessitating sorting. The drying device is then used to dry the shredded sprouts.
[0025] The drying box 1 is the primary location for drying sprouts. After shredded sprouts are fed through the feed port 4, they flow down the top pulley conveyor mechanism 2 to the bottom. During this process, a hot air source 5 at the bottom outputs a hot air flow for drying. This hot air flows through the conveyor pipe 6 and along the air distribution plate 7 into the drying box 1, drying the sprouts inside. The hot air flow, which carries away moisture during the drying process, is discharged through the air outlet 10. Multiple air holes 9, evenly spaced on the conveyor belt 3 of the pulley conveyor mechanism 2, facilitate ventilation and enhance the drying effect.
[0026] During the sorting process, the hot air flow discharged from the above-mentioned gas separation plate 7 plays a role in gas separation. When the hot air flow reaches the pulley conveyor mechanism 2 at the bottom, it will blow up the unqualified sprouts and blow them into the screening channel 12. The unqualified sprouts will be discharged along the screening channel 12.
[0027] Therefore, this combined sprout sorting and drying device significantly improves efficiency compared to manual sorting. It also achieves simultaneous sorting and drying, utilizing the hot air flow from the drying process as a power source for sorting, saving energy and improving production efficiency. Furthermore, since both sorting and drying utilize hot air flow, it also reduces the space required for the equipment compared to separate sorting and drying operations.
[0028] It should be noted that in the above process, since the sprouts entering the pulley conveyor mechanism 2 at the top for drying have undergone a certain degree of drying, the unqualified sprouts have been effectively dried when they enter the pulley conveyor mechanism 2 at the bottom, and are not easy to stick to the surface of the conveyor belt 3 of the pulley conveyor mechanism 2, and are more likely to be blown away.
[0029] Please refer to Figure 1 and Figure 2 In some implementations of the present embodiment, the material receiving member is a vibrating screen 8. A protective cover 11 is provided on the top of the vibrating screen 8, and the screening channel 12 is formed between the protective cover 11 and the vibrating screen 8. The feeding end of the vibrating screen 8 is located above the pulley conveying mechanism 2 at the bottom, and the side wall of the drying box 1 is connected with a feeding channel 13. The screening channel 12 is connected to the feeding channel 13, and the feeding channel 13 is connected to the feed port 4 at the top of the drying box 1. The vibrating screen 8 can be used to further screen the unqualified sprouts blown into the screening channel 12, and the smaller unqualified sprouts are screened out through the sieve holes of the vibrating screen 8. Some of the larger sprouts re-enter the drying box 1 along the feeding channel 13 for secondary sorting. In this way, some qualified sprouts can be avoided from being discharged.
[0030] Preferably, in this embodiment, a waste recovery box 15 is provided on the discharging side of the mesh of the vibrating screen 8. The waste recovery box 15 recovers the unqualified sprouts screened out by the mesh of the vibrating screen 8.
[0031] Please refer to Figure 1In some implementations of this embodiment, a first spiral feeding mechanism 14 is provided in the feeding channel 13. The first spiral feeding mechanism 14 is used to feed the material (the unqualified sprouts discharged from the discharge end of the vibrating screen 8) into the feed port 4 at the top of the drying box 1. The first spiral feeding mechanism is mainly used to re-convey the unqualified sprouts discharged from the discharge end of the vibrating screen 8 to the feed port 4 at the top of the drying box 1. Specifically, the feeding channel 13 of this embodiment includes a vertical pipe 131 and a horizontal pipe 132 connected in sequence. The first spiral feeding mechanism 14 includes a vertical spiral feeder 141 and a horizontal spiral feeder 142. The vertical spiral feeder 141 is arranged in the vertical pipe 131, and the horizontal spiral feeder 142 is arranged in the horizontal pipe 132.
[0032] Preferably, in this embodiment, the horizontal inclination angle of the conveyor belt 3 of the above-mentioned pulley conveying mechanism 2 is 35°~45°. The specific horizontal inclination angle adopted in this embodiment is 45°. If the horizontal inclination angle of the conveyor belt 3 is too large, it is easy to cause the sprouts to slide down quickly. If the horizontal inclination angle of the conveyor belt 3 is too small, it is easy to cause the unqualified sprouts to be blown up and difficult to enter the screening channel 12. The horizontal inclination angle of the above-mentioned conveyor belt 3 of 35°~45° can facilitate the hot air flow to act evenly on the conveyor belt 3, and can effectively make the blown unqualified sprouts enter the screening channel 12. Another thing is that the horizontal inclination angle of the above-mentioned conveyor belt 3 of 35°~45° can also make the hot air flow discharged from the gas distribution plate 7 blow out obliquely, so as to avoid part of the hot air flow entering the screening channel 12 and being wasted.
[0033] Please refer to Figure 1 Preferably, in this embodiment, the discharge end of the belt conveyor mechanism 2 at the bottom is provided with a recovery funnel 17 for receiving good quality sprouts. The recovery funnel 17 is mainly used to recover good quality sprouts discharged from the discharge end of the belt conveyor mechanism 2 at the bottom.
[0034] Please refer to Figure 1 In this embodiment, the recovery hopper 17 is connected to a second spiral feeder 16. The outlet of the second spiral feeder 16 extends out of the drying box 1. The second spiral feeder 16 is used to deliver the good quality sprouts along the outlet. The second spiral feeder is primarily used to quickly discharge the good quality sprouts in the recovery hopper 17 out of the drying box 1.
[0035] In some implementations of the present embodiment, the horizontal inclination angle of the screening channel 12 is 0° to 90°. When unqualified sprouts are blown into the screening channel 12, part of the hot air flow will enter the screening channel 12 and be wasted. Therefore, the horizontal inclination angle of the screening channel 12 is 0° to 90°, which can block most of the hot air flow by the screening channel 12, thereby further reducing the hot air flow entering the screening channel 12. It should be noted that, in the present embodiment, the sieve holes of the vibrating screen 8 are only opened at the recovery funnel 17 and are connected to the recovery funnel 17. Therefore, the hot air flow can be blocked by the vibrating screen 8 in the drying box 1.
[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
