Description

Technical Field

[0001] This utility model relates to the field of drying machine technology, specifically to a powder drying device. Background Technology

[0002] Rice noodles are a traditional Chinese food, belonging to the category of dried starch products. They are mainly made from raw materials such as rice, sweet potatoes, mung beans, and peas, and processed into long, thin strips. To remove moisture from rice noodles and extend their shelf life while maintaining their shape and texture, drying is an essential step in the production process. Currently, most rice noodle drying machines are used.

[0003] Patent CN212747196U discloses a rice noodle dryer, including a drying chamber. A motor is located at the bottom of the drying chamber, with its output shaft connected to a rotating shaft. The rotating shaft houses a rice noodle rack and rice noodle hooks. An air heating chamber is located on the side of the drying chamber, with an air inlet on its side. A blower is installed inside the air heating chamber, with heating wires on its side. The air outlet of the air heating chamber is connected to the lower end of the drying chamber. An exhaust pipe is located on one side wall of the upper end of the drying chamber. A door is hinged to the front of the drying chamber. The output shaft of the motor drives the rotating shaft, which in turn drives the rice noodle rack synchronously. Outside air is drawn into the air heating chamber by the blower, and the heating wires heat the air. The heated air then flows through the air outlet of the air heating chamber to the bottom of the drying chamber to heat and dry the rice noodles. A fan accelerates the airflow inside the drying chamber, effectively improving drying efficiency and facilitating feeding and use.

[0004] However, the rice noodle dryer mentioned above still has the following problems in actual use:

[0005] Before drying, the powder is less resilient. When the not-fully-dried powder is suspended on the racks inside the dryer, some of it may break due to its own weight and fall to the bottom of the dryer. Because undried powder is sticky, these fragments that fall to the ground will adhere tightly to the surface after drying, significantly increasing the difficulty of cleaning for workers.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-6A powder drying device includes a dryer body 1 and two boxes 2 installed on one side of the dryer body 1. A conveying mechanism is connected to the bottom surface inside the dryer body 1. A collection box 4 is fixedly connected to the bottom surface inside the dryer body 1 near the box 2. The output end of the conveying mechanism is located above the collection box 4. A rotating component is connected to the end of the collection box 4 near the box 2. A pad 8 is connected to the other end of the rotating component. The other end of the pad 8 faces the conveying mechanism. A cleaning brush is fastened to the upper surface of the collection box 4 away from the box 2 by a bolt No. 1. The bristles of the cleaning brush abut against the conveying mechanism.

[0025] like Figures 1 to 6 As shown, when using the powder drying device of this utility model, the powder to be dried is first suspended on several supports inside the dryer body 1, then the inclined frame at the door of the dryer body 1 is removed, and then the two boxes 2 are closed, so that the powder inside can be dried through the dryer body 1. During the process from hanging the powder on the internal support of the dryer body 1 to opening the door 2 after drying, a small amount of powder will fall onto the conveying mechanism. Therefore, while closing the door 2 for drying, the pad 8 needs to be rotated and raised towards the door 2 via the rotating component to prevent the pad 8 from affecting the material falling onto the conveying mechanism. Then, the conveying mechanism is turned on, and it will transport the powder that has fallen onto the surface to the collection box 4. This powder will then fall into the collection box 4 by gravity and be collected. Even if some powder does not fall, it will be scraped off by the cleaning brush. Because the conveying mechanism is continuously circulating, it can be ensured that all the powder that falls off will be scraped off, thus avoiding the situation where the powder sticks to the conveying mechanism and is difficult to clean after it is completely dry.

[0026] As a preferred embodiment of this utility model, the conveying mechanism includes a motor 3, a conveyor belt 7, and two drive rollers 6. The outer wall of the motor 3 is fixedly connected to the outer wall of the dryer body 1. The output shaft of the motor 3 is fixedly connected to one end of one of the drive rollers 6. The two drive rollers 6 are arranged in parallel. Both drive rollers 6 are located inside the dryer body 1, and both ends of the two drive rollers 6 are rotatably connected to the inner wall of the dryer body 1. The conveyor belt 7 is sleeved on the outside of the two drive rollers 6. The end of the pad plate 8 away from the collection box 4 faces the turning point of the conveyor belt 7.

[0027] More specifically, after the powder is suspended on several supports inside the dryer body 1, some of the powder will fall onto the surface of the conveyor belt 7. Since the conveyor belt 7 will continue to rotate under the action of the motor 3 and the two drive rollers 6, the powder that falls onto the surface of the conveyor belt 7 will move to the collection box 4 on its own. And since the conveyor belt 7 changes direction at this point, this part of the powder will fall into the collection box 4 on its own for collection, reducing the difficulty of cleaning later.

[0028] As a preferred embodiment of this utility model, a support plate 10 is fixedly connected to the lower end of the inner wall of the dryer body 1, and the support plate 10 is located inside the conveyor belt 7.

[0029] More specifically, by setting up the support plate 10, the overall support of the conveyor belt 7 can be improved, preventing the conveyor belt 7 from being damaged faster when workers enter the dryer body 1 and stand on the conveyor belt 7.

[0030] As a preferred embodiment of this utility model, the rotating assembly includes a rotating block 13, a rotating rod 14, and two fixed blocks 11. The lower ends of the two fixed blocks 11 are respectively fixedly connected to the upper surfaces of both ends of the collection box 4. One end of the rotating block 13 is fixedly connected to the middle of one end of the pad 8. The rotating rod 14 passes through the rotating block 13 and the two fixed blocks 11. The outer wall of the rotating rod 14 is rotatably connected to the inner wall of the passage of the rotating block 13. The outer wall of the rotating rod 14 is fixedly connected to the inner wall of the passage of the two fixed blocks 11.

[0031] More specifically, when the door 2 is opened, the pad 8 will tilt and collapse towards the conveyor belt 7 under the action of the rotating block 13 and the rotating rod 14. This can fill the gap between the door of the dryer body 1 and the conveyor belt 7, thus making it convenient for workers to freely enter and exit the dryer body 1 using trolleys or other tools.

[0032] In addition, during the drying process inside the dryer body 1, the pad 8 is erected and placed against the inner wall of the door 2, thereby preventing the pad 8 from obstructing the powder being conveyed on the surface of the conveyor belt 7.

[0033] As a preferred embodiment of this utility model, a locking strip 9 is fixedly connected to the side of the rotating block 13 away from the pad 8, and a slot 401 is opened on one side of the upper end of the collection box 4, with the outer wall of the locking strip 9 abutting against the inner wall of the slot 401.

[0034] More specifically, by setting the clip 9 and the slot 401, firstly, the pad 8 can be restricted to tilting only towards the conveyor belt 7; secondly, during the drying process, it can be squeezed onto the surface of the clip 9 through the door 2, thereby restricting the pad 8 to remain upright and prevent it from tilting towards the conveyor belt 7 due to vibration or other reasons.

[0035] As a preferred embodiment of this utility model, a magnet 12 is fixed on the side of the bayonet 401 that contacts the card strip 9, and the bayonet 401 and the magnet 12 on the card strip 9 are attracted to each other.

[0036] More specifically, by setting up the magnet 12, it is possible to easily limit the pad 8 during the process of raising the pad 8 to closing the box door 2, so as to prevent the pad 8 from falling towards the conveyor belt 7 on its own.

[0037] As a preferred embodiment of this utility model, the material collection box 4 is provided with a slag removal port through one end located outside the dryer body 1. The inner wall of the slag removal port is slidably connected to a slag removal door 5, which is fastened to the dryer body 1 by a No. 2 bolt.

[0038] More specifically, by setting up a slag removal port and a slag removal door 5, the dry powder that falls inside the collection box 4 can be discharged to the outside.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
