Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a konjac flour drying device. Background Technology

[0002] Potato flour, also known as konjac powder or konjac mannan, is a natural high-molecular-weight polysaccharide extracted and processed from konjac tubers. Drying konjac flour is an important step in the konjac processing process, and proper drying can ensure the quality and shelf life of konjac flour.

[0003] Traditional konjac processing powder drying equipment generally uses static drying. During the drying process, konjac powder is prone to uneven heating, and there may be differences in different locations. Uneven heating of konjac powder results in poor drying effect and affects the quality of konjac powder products.

[0004] For example, statically placed konjac powder generally has a certain thickness. The lower the layer of konjac powder, the less heat it receives. The upper layer of konjac powder is prone to over-drying, which may cause it to darken in color, become brittle, or even burn, affecting the product's appearance and taste. Utility Model Content

[0005] This utility model discloses a konjac flour drying device, which aims to solve the technical problem that konjac flour drying devices generally use static drying, which makes the konjac flour prone to uneven heating during the drying process, with differences in different locations. This uneven heating of the konjac flour results in poor drying effect and affects the quality of konjac flour products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A konjac flour drying device includes a base and further includes:

[0008] Auxiliary mechanism used to improve the flowability of konjac flour;

[0009] A drying cylinder is installed on the top outer wall of the base, and a hopper is installed on the top outer wall of the drying cylinder. A guide plate is connected to the outer wall of the drying cylinder near the bottom. The inner wall of the drying cylinder and the inner wall of the base are connected to the same rotating cylinder through a bearing. Four equally spaced levers are installed on the outer wall of the rotating cylinder. A rotating rod is connected to the inner wall of the rotating cylinder through a bearing. Spiral blades are connected to the outer circumference of the rotating rod. Several air holes are opened on the outer circumference of the rotating rod. A transmission mechanism is also provided at the bottom of the base.

[0010] The transmission mechanism includes a motor mounted on the outer wall of the bottom of the base. A connecting rod is mounted on the output end of the motor. A first gear is sleeved on the outer wall of the connecting rod and the outer wall of the rotating cylinder. A second gear is sleeved on the outer wall of the connecting rod and the outer wall of the rotating rod. The rotating rod and the spiral blade are both hollow structures, and the rotating rod and the spiral blade are in communication. The drying cylinder is a double-layer vacuum structure. The deflector is a spiral structure. The first gear and the second gear mesh, and the diameter of the first gear is smaller than the diameter of the second gear.

[0011] In this design, the hollow rotating rod and spiral blades, along with the air vents, work together to dry the konjac powder. The first and second gears drive the rotating drum and rod to rotate. Because the diameter of the first gear is smaller than that of the second gear, the rotating rod's rotation speed is lower than that of the drum. The slower-rotating spiral blades slowly transport the konjac powder from the top of the drying drum to the bottom, while the relatively faster-rotating lever pushes the dried konjac powder to the edge of the drying drum, where it is finally conveyed away from the guide plate. The konjac powder tumbles continuously under the transport of the spiral blades and is dried together by the hot airflow blown out by the spiral blades and air vents, resulting in more uniform heating and better drying, which is beneficial for improving the quality of the konjac powder product.

[0012] In a preferred embodiment, the auxiliary mechanism includes a stirring rod and an elastic strip mounted on the outer wall of the rotating rod, and a plurality of equally spaced protrusions are installed on the inner wall of the drying cylinder. The elastic strip is used in conjunction with the protrusions, and the stirring rod is in contact with the inner wall of the hopper.

[0013] The stirring rod rotates along with the rotating rod, which can enhance the fluidity of the konjac powder in the hopper and prevent the hopper from clogging. During the rotation, the elastic strip hits the protrusion and generates vibration. On the one hand, it drives the hopper to vibrate, which is conducive to the feeding of the hopper. On the other hand, it drives the spiral blade to vibrate, which intensifies the tumbling of the konjac powder and helps to improve the drying effect of the konjac powder.

[0014] As can be seen from the above, a konjac flour drying device includes a base and also includes:

[0015] Auxiliary mechanism used to improve the flowability of konjac flour;

[0016] A drying cylinder is installed on the top outer wall of the base, and a hopper is installed on the top outer wall of the drying cylinder. A guide plate is connected to the outer wall of the drying cylinder near the bottom. The inner wall of the drying cylinder and the inner wall of the base are connected to the same rotating cylinder through a bearing. Four equally spaced levers are installed on the outer wall of the rotating cylinder. A rotating rod is connected to the inner wall of the rotating cylinder through a bearing. Spiral blades are connected to the outer circumference of the rotating rod. Several air holes are opened on the outer circumference of the rotating rod. A transmission mechanism is also provided at the bottom of the base.

[0017] The transmission mechanism includes a motor mounted on the outer wall of the base bottom. A connecting rod is installed at the output end of the motor. A first gear is sleeved on the outer wall of the connecting rod and the outer wall of the rotating cylinder. A second gear is sleeved on the outer wall of the connecting rod and the outer wall of the rotating rod. The rotating rod and the spiral blades are both hollow structures, and the rotating rod and the spiral blades are interconnected. The drying cylinder is a double-layer vacuum structure, and the deflector is a spiral structure. The first gear meshes with the second gear, and the diameter of the first gear is smaller than the diameter of the second gear. The konjac flour drying device provided by this utility model has the technical effect of improving the drying effect and improving the quality of konjac flour products. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The konjac flour drying device disclosed in this utility model is mainly applied to scenarios where traditional konjac flour drying devices generally use static drying, and the konjac flour is prone to uneven heating during the drying process, with differences in different locations. Uneven heating of the konjac flour results in poor drying effect and affects the quality of the konjac flour product.

[0025] Reference Figure 1 , Figure 2 and Figure 3 A konjac flour drying device, comprising a base 1, and further comprising:

[0026] Auxiliary mechanism used to improve the flowability of konjac flour;

[0027] A drying cylinder 2 is fixedly installed on the top outer wall of the base 1. A hopper 3 is fixedly installed on the top outer wall of the drying cylinder 2. A guide plate 15 is fixedly connected to the outer wall of the drying cylinder 2 near the bottom. The inner wall of the drying cylinder 2 and the inner wall of the base 1 are movably connected to the same rotating cylinder 10 through bearings. Four equally spaced lever plates 11 are fixedly installed on the outer wall of the rotating cylinder 10. A rotating rod 5 is movably connected to the inner wall of the rotating cylinder 10 through bearings. A spiral blade 6 is fixedly connected to the outer circumference of the rotating rod 5. Several air holes 7 are opened on the outer circumference of the rotating rod 5. A transmission mechanism is also provided at the bottom of the base 1.

[0028] The transmission mechanism includes a motor 4 fixedly installed on the outer wall of the bottom of the base 1. A connecting rod is fixedly installed at the output end of the motor 4. A first gear 8 is sleeved on the outer wall of the connecting rod and the outer wall of the rotating cylinder 10. A second gear 9 is sleeved on the outer wall of the connecting rod and the outer wall of the rotating rod 5. The first gear 8 and the second gear 9 mesh with each other, and the diameter of the first gear 8 is smaller than the diameter of the second gear 9.

[0029] The rotating rod 5 and the spiral blade 6 are both hollow structures, and the rotating rod 5 and the spiral blade 6 are connected to each other for drying konjac flour. The drying cylinder 2 is a double-layer vacuum structure with heat preservation effect. The grating plate 11 is a spiral structure to improve the feeding effect.

[0030] It should be noted that the bottom end of the rotating rod 5 is connected to an air pipe for conveying hot air (this structure is not shown).

[0031] In actual use, hot air enters from the bottom of the rotating rod 5, continuously heating the rotating rod 5 and the spiral blade 6. Finally, the hot air is discharged from the air hole 7. The motor 4 drives the first gear 8 and the second gear 9 on the connecting rod to rotate, which in turn drives the rotating drum 10 and the rotating rod 5 to rotate through the other first gear 8 and the second gear 9 respectively. The konjac powder slowly falls from the hopper 3 to the top of the drying drum 2 in small amounts. As the spiral blade 6 rotates slowly, the konjac powder slowly moves towards the bottom of the drying drum 2. It is dried during the tumbling and moving process. After reaching the bottom of the drying drum 2, it is pushed to the edge of the drying drum 2 by the relatively fast rotating plate 11, and finally discharged from the guide plate 15.

[0032] Reference Figure 2 and Figure 4 In a preferred embodiment, the auxiliary mechanism includes a stirring rod 12 and an elastic strip 13 fixedly installed on the outer wall of the rotating rod 5. Several equally spaced protrusions 14 are fixedly installed on the inner wall of the drying cylinder 2. The elastic strip 13 works in conjunction with the protrusions 14. The stirring rod 12 is in contact with the inner wall of the hopper 3.

[0033] Specifically, when the hopper 3 is discharging material, the stirring rod 12 rotates along with the rotating rod 5, which can enhance the fluidity of the konjac powder in the hopper 3 and prevent blockage at the outlet of the hopper 3. During the rotation of the rotating rod 5, the elastic strip 13 is obstructed by the protrusion 14, bends and deforms, and then straightens, thereby hitting the protrusion 14 and generating vibration. On the one hand, it drives the hopper 3 to vibrate, which is beneficial for discharging material from the hopper 3, and on the other hand, it drives the spiral blade 6 to vibrate, which intensifies the tumbling of the konjac powder.

[0034] Working principle: During use, hot air enters from the bottom of the rotating rod 5, continuously heating the rotating rod 5 and the spiral blades 6. Finally, the hot air is discharged from the air hole 7. The motor 4 drives the first gear 8 and the second gear 9 on the connecting rod to rotate, which in turn drives the other first gears 8 and second gears 9 to rotate the rotating drum 10 and the rotating rod 5 respectively. The konjac powder slowly falls from the hopper 3 in small amounts to the top of the drying drum 2. As the spiral blades 6 slowly rotate, the konjac powder slowly moves towards the bottom of the drying drum 2, where it is dried during the tumbling process. After reaching the bottom, the powder is pushed to the edge of the drying cylinder 2 by the relatively fast rotating plate 11, and finally discharged from the guide plate 15. When the powder is discharged from the hopper 3, the stirring rod 12 rotates with the rotating rod 5, which can enhance the fluidity of the konjac powder in the hopper 3 and prevent blockage at the discharge port of the hopper 3. During the rotation with the rotating rod 5, the elastic strip 13 is obstructed by the protrusion 14, bends and deforms, and then straightens, thereby hitting the protrusion 14 and generating vibration. On the one hand, it drives the hopper 3 to vibrate, which is beneficial for the discharge of the hopper 3, and on the other hand, it drives the spiral blade 6 to vibrate, which intensifies the tumbling of the konjac powder.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
