Technical Field
[0001] This utility model relates to the field of potato starch processing technology, and in particular to a drying drum for drying potato starch. Background Technology
[0002] In modern food processing, potato starch production is crucial. As a basic raw material widely used in food, papermaking, textiles, and many other industries, the quality of potato starch directly affects the quality of downstream products. With the continuous development of the food industry and the increasing market demand for high-quality potato starch, the drying process has become a critical step. Traditional methods for drying potato starch vary, but most suffer from low efficiency and uneven heating. Early, simple drying equipment relied solely on natural ventilation or simple hot plate heating, which was not only time-consuming but also failed to guarantee the quality of starch drying. However, with technological advancements, a drying drum specifically designed for drying potato starch has emerged.
[0003] Most drying drums used for drying potato starch typically consist of a drying drum, a feed pipe, a filter screen, and a drive source. In operation, the heating tank is started, and the potato starch slurry to be dried enters the rotating drying drum through the feed inlet and is filtered through the filter screen. Inside, it is repeatedly lifted and scattered by the internal lifting plates, fully dispersing in the hot airflow. Once the set dryness level is reached, it is collected from the discharge outlet, completing the drying process.
[0004] In existing technologies, some drying drums typically use a filter screen to screen potato starch during feeding. After screening, the impurities remain on the filter plate. During subsequent starch screening, the impurities move with the starch to the later drying steps. Moreover, since only one screening is performed, it is difficult to completely remove the impurities. Consequently, the residual impurities affect the contact between the starch and the hot air, resulting in poor drying effect. Therefore, to address the above shortcomings, a drying drum for drying potato starch is proposed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying drum for drying potato starch. This invention aims to improve the problem that impurities follow the starch into the drying step during the screening process and that it is difficult to completely screen out impurities in a single screening, resulting in poor drying effect.

A drying assembly is fixedly connected to the right side of the housing 1. The drying assembly includes a support frame 2, the left end of which is fixedly connected to the right end of the housing 1. A drying cylinder 3 is rotatably connected to the top of the support frame 2 to ensure the stability of the drying cylinder 3 during operation. Multiple lifting plates are fixedly connected inside the drying cylinder 3. An inlet hole 4 is provided at the top of the housing 1 to introduce the potato starch slurry to be dried into the housing 1. Two telescopic rods 5 are fixedly connected to the left side of the top of the housing 1. A telescopic spring 6 is sleeved on the outside of the telescopic rods 5 to provide buffering and restoring force.
[0026] One end of the telescopic spring 6 is fixedly connected to the inside side of the box 1, and the other end of the telescopic spring 6 is fixedly connected to the top left side of the inclined filter plate 7. The bottom ends of the two telescopic rods 5 are fixedly connected to the inclined filter plate 7, which is responsible for screening impurities in potato starch. The outside of the inclined filter plate 7 is movably connected to the inside of the box 1. Two gathering blocks 8 are fixedly connected to the top left side of the inclined filter plate 7, which will initially gather the starch slurry flowing from the feed hole 4 on the inclined filter plate 7, so that the starch flows to the area with the best filtration effect, speeding up the filtration process and improving the overall working efficiency. The inside right end of the box 1 is fixedly connected to the rotating rod 9, which provides the rotation fulcrum of the inclined filter plate 7 and ensures the stability of the inclined state of the inclined filter plate 7 during the filtration process.
[0027] The right side of the inclined filter plate 7 is rotatably connected to the outside of the rotating rod 9. The left side of the box 1 is fixedly connected to a temporary storage compartment 10 to provide a temporary storage space. The left side of the box 1 is fixedly connected to a receiving block 11. A transmission pipe is provided on the side of the receiving block 11 near the feed hole 4. The top of the receiving block 11 is fixedly connected to a drive motor 12 to provide driving force. The drive end of the drive motor 12 is fixedly connected to an auger rod 13 to provide transmission.
[0028] The bottom end of the receiving block 11 is rotatably connected to the driving bevel gear 14 to provide a transmission effect. The external part of the auger rod 13 is rotatably connected to the inside of the receiving block 11. The bottom end of the auger rod 13 is fixedly connected to the top of the driving bevel gear 14. The left bottom end of the housing 1 is rotatably connected to the driven bevel gear 15. The driving bevel gear 14 and the driven bevel gear 15 are meshed to ensure stable transmission. The right end of the driven bevel gear 15 is fixedly connected to the auger rod 16. The left side of the auger rod 16 is rotatably connected to the left side of the bottom end of the housing 1.
[0029] Reference Figure 1 , Figure 2 and Figure 4 A rotating motor 17 is fixedly connected to the rear end of the housing 1. An agitating roller 18 is fixedly connected to the drive end of the rotating motor 17. The agitating roller 18 is rotatably connected to the inside of the feed hole 4 to ensure that the starch slurry can flow in stably and smoothly. A drive wheel 19 is fixedly connected to the front end of the agitating roller 18. The rear end of the drive wheel 19 is rotatably connected to the top front end of the housing 1. A transmission rod 20 is rotatably connected to the bottom end of the housing 1 to transmit the power from the drive wheel 19. The transmission rod 20 is rotatably connected to the bottom end of the housing 1. A driven wheel 21 is fixedly connected to the front end of the transmission rod 20. A belt 22 is sleeved on the outside of the drive wheel 19 and the driven wheel 21. Two cams 23 are fixedly connected to the rear end of the transmission rod 20. The outside of the cams 23 contacts the bottom end of the inclined filter plate 7 to give the inclined filter plate 7 a vibration effect.
[0030] Working principle: First, the heating system is started to preheat the drying cylinder 3 to prepare the drying environment. At the same time, the potato starch slurry to be dried is transported to the feed hole 4 at the top of the box 1. At this time, the rotating motor 17 is started. The rotating motor 17 drives the stirring roller 18 to rotate inside the feed hole 4. The rotation of the stirring roller 18 breaks the accumulation of the potato starch slurry with a certain viscosity, ensuring that the starch slurry can flow in stably and smoothly, and avoiding blockage of the feed hole 4.
[0031] As the rotating motor 17 operates, the drive end causes the driving wheel 19 to rotate synchronously. The driving wheel 19 drives the driven wheel 21 at the front end of the transmission rod 20 to rotate via the belt 22, causing the two cams 23 at the rear end of the transmission rod 20 to rotate accordingly. During the rotation, the cams 23 continuously strike the bottom end of the inclined filter plate 7, giving the inclined filter plate 7 a vibration effect. This not only makes the starch flowing into the inclined filter plate 7 from the feed hole 4 more evenly distributed and speeds up the filtration speed, but also effectively prevents impurities from clogging the filter holes.
[0032] Impurities filtered by the inclined filter plate 7 slide naturally into the temporary storage bin 10 on the left side of the housing 1 due to the natural tilt of the filter plate 7, preventing them from accumulating on the filter plate and mixing with subsequent starch materials. The filtered starch is then sent to the drying cylinder 3 by the auger rod 16, while the starch and impurities in the temporary storage bin 10 naturally fall into the auger rod 13. At this time, the drive motor 12 is started, which drives the auger rod 13 to rotate. The rotation of the auger rod 13 sends the starch back to the inclined filter plate 7 for secondary screening, allowing some starch that might have been discarded due to impurities to re-enter the screening process, reducing starch waste.
[0033] The starch that reaches the drying drum after passing through the auger rod 16 will be repeatedly lifted and scattered by multiple lifting plates rotating in the drying drum 3, so that the starch is fully dispersed in the hot air flow. As the drying drum 3 continues to rotate, the starch gradually moves towards the discharge port. When the set degree of dryness is reached, it is collected from the discharge port, completing the drying process. When it is necessary to clean the impurities accumulated in the temporary storage bin 10, simply place the container under the transmission pipe set on the side of the receiving block 11 near the inlet hole 4, and the impurities in the temporary storage bin 10 will naturally fall into the container. The operation is convenient and the equipment is easy to maintain.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
