Description

Technical Field

[0001] This utility model belongs to the field of konjac food production, and in particular relates to a drying equipment for konjac food production. Background Technology

[0002] As a representative of healthy foods, the drying process in konjac food production is crucial to product quality. The drying step in konjac food production is a key step determining the final product quality. After being washed, sliced, or shaped, konjac raw materials need to be dried to remove excess moisture, achieving the ideal texture and storage requirements. Traditional drying methods include natural sun-drying and hot air drying. A proper drying process not only preserves the nutritional components of konjac but also improves its taste and shelf life.

[0003] Comparing with Chinese Patent CN218097040U, a tunnel-type konjac food drying production line is disclosed, including a drying box, an inlet on the top wall of the drying box, and an outlet at the bottom of the drying box. Several receiving plates located below the inlet are rotatably connected inside the drying box. The receiving plates are used to flip the incoming konjac food downwards sequentially. The receiving plates are arranged vertically inside the drying box. A motor is installed on the drying box to drive the rotation of the receiving plates. Heating equipment is provided inside the drying box to dry the konjac food on the receiving plates. By rotating the receiving plates, the konjac food flips on the plates as it falls, allowing the position of the konjac food inside the drying box to change and enabling multi-angle drying, thus improving the drying efficiency of the konjac food.

[0004] However, the aforementioned patented raw materials are flipped and fall too quickly and only flipped two or three times, making it difficult to ensure that the materials are fully exposed to the hot airflow during the drying process. This can easily cause clumping or localized overheating, reducing the uniformity of drying. Therefore, a new type of equipment needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for konjac food production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drying device for konjac food production includes a frame device for supporting the inlet and outlet of raw materials, and a box-shaped device disposed in the middle of the frame device for rotating and continuously conveying the raw materials. A gas circulation device is disposed at the top of the frame device for circulating hot air to dry the materials at both ends. The frame device includes a frame body with two fixed frames symmetrically disposed in the middle, and inlet and outlet components disposed at both ends of the frame body. The box-shaped device includes a rotating cylinder with a spiral pusher plate disposed on its inner wall and a power component for driving rotation disposed on its outer side. The gas circulation device includes a gas supply pipe, on which a drying chamber, a crossflow fan, and a heating chamber are sequentially mounted.

[0008] Furthermore: the feeding and discharging assembly includes a feeding cover and a discharging cover, a feeding hopper is fixedly provided on the feeding cover, and a discharging pipe is fixedly provided at the bottom of the discharging cover.

[0009] Furthermore: the feed hopper is inclined downwards, and the discharge pipe is cylindrical.

[0010] Furthermore: the power assembly includes a passive gear ring disposed on the outer periphery of the tilting cylinder, a drive gear meshing on one side of the passive gear ring, and an electric motor disposed in the middle of the drive gear.

[0011] Furthermore: the tilting cylinder and the fixed frame are connected by bearings, and the motor and the fixed frame are connected by bolts.

[0012] Furthermore, the spiral pusher plate has a thickness of 1 mm and a height of 5 cm.

[0013] Furthermore, the heating chamber contains a number of heating wires evenly distributed inside.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The rotating drum drives the raw material to rise and fall repeatedly, combined with the continuous advancement of the spiral pusher plate (optimized design with a thickness of 1mm and a height of 5cm), so that the material is fully exposed to the hot airflow during the drying process, avoiding clumping or local overheating and improving the uniformity of drying.

[0016] 2. The air circulation device (drying box + heating box + crossflow fan) forms a closed-loop airflow. The hot air is dried and dehumidified and then reheated for reuse, which significantly improves thermal efficiency and shortens drying time. The airflow circulation design reduces heat loss. The air heated by the heating wire is dehumidified in the drying box and then reheated, which reduces energy consumption. The low-energy fan maintains the airflow circulation, which is more energy-efficient than traditional drying equipment.

[0017] 3. The inclined feed hopper and the circular discharge pipe, together with the spiral push plate, realize the automatic feeding, turning and drying and discharging of raw materials in a continuous process, reduce manual intervention and improve production efficiency; the motor drives the turning drum through the gear set (drive gear + driven gear ring), and the fixed bearing ensures smooth operation, which is suitable for long-term continuous operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 A drying equipment for konjac food production includes a frame device for supporting the inlet and outlet of raw materials, a box device in the middle of the frame device for rotating and turning the raw materials and continuously conveying them, and an air circulation device at the top of the frame device for connecting the two ends to circulate and convey hot air for drying.

[0026] In this embodiment: the frame device includes a frame body 101, with two fixed frames 106 symmetrically arranged in the middle of the frame body 101, and feeding and discharging components at both ends of the frame body 101; the feeding and discharging components include a feeding cover 102 and a discharging cover 104, a feeding hopper 103 is fixedly arranged on the feeding cover 102, and a discharging pipe 105 is fixedly arranged at the bottom of the discharging cover 104; the feeding hopper 103 is inclined downward, and the discharging pipe 105 is a cylindrical tube; the raw material is poured in from the feeding hopper 103, and the raw material passes through the feeding cover 102 supported by the frame body 101 and enters the rotating drum 201; the dried raw material moves towards the discharging cover 104 as pushed by the spiral pusher plate 202 on the inner wall of the rotating drum 201, and is discharged from the discharging pipe 105; the fixed frames 106 are used to support the rotating drum 201 to rotate flexibly;

[0027] In this embodiment: the box-shaped device includes a tilting cylinder 201, a spiral pusher plate 202 is provided on the inner wall of the tilting cylinder 201, and a power component for driving rotation is provided on the outer side of the tilting cylinder 201; the power component includes a passive gear ring 203 provided on the outer periphery of the tilting cylinder 201, a drive gear 204 meshing on one side of the passive gear ring 203, and a motor 205 provided in the middle of the drive gear 204; the tilting cylinder 201 and the fixed frame 106 are connected by bearings, and the motor 205 and the fixed frame 106 are connected by bolts; the spiral pusher plate 202 is 1 mm thick and 5 cm high; the motor 205 drives the drive gear 204 to mesh with the passive gear ring 203 to rotate, causing the tilting cylinder 201 to rotate under the support of the fixed frame 106. During the rotation of the tilting cylinder 201, the raw material is driven to rise and fall freely. The dried raw material moves towards the discharge cover 104 as pushed by the spiral pusher plate 202 on the inner wall of the tilting cylinder 201.

[0028] In this embodiment, the air circulation device includes an air supply pipe 301, on which a drying chamber 302, a crossflow fan 303, and a heating chamber 304 are sequentially installed. Several heating wires 305 are evenly distributed inside the heating chamber 304. The crossflow fan 303 drives the air flow in the air supply pipe 301, so that the airflow in the rotating drum 201 first enters the drying chamber 302 from the feed cover 102 along the air supply pipe 301 for drying, then flows into the heating chamber 304 to be heated by the heating wires 305, and then flows back into the rotating drum 201 from the discharge cover 104, forming a circulating airflow to dry the raw materials.

[0029] Working principle: Raw materials are poured into the feed hopper 103 and pass through the feed cover 102 supported by the frame 101 into the tilting drum 201. The fixed frame 106 supports the motor 205, which drives the active gear 204 to mesh with the passive gear ring 203 to rotate, causing the tilting drum 201 to rotate under the support of the fixed frame 106. During the rotation of the tilting drum 201, the raw materials are lifted and fall freely. At the same time, the crossflow fan 303 pushes the air in the air supply pipe 301 to flow, so that the airflow in the tilting drum 201 first enters the drying chamber 302 from the feed cover 102 along the air supply pipe 301 for drying, and then flows into the heating chamber 304 to be heated by the heating wire 305. Then it flows back into the tilting drum 201 from the discharge cover 104, forming a circulating airflow to dry the raw materials. After drying, the raw materials are pushed towards the discharge cover 104 by the spiral pusher plate 202 on the inner wall of the tilting drum 201 and are discharged from the discharge pipe 105.
