Detailed Implementation

[0030] like Figures 1-5 As shown, a konjac flour puffing device includes a tank 1, a rotating shaft 4 inside the tank 1, and movable scrapers 7 on both sides of the rotating shaft 4. The scrapers 7 move and abut against the inner wall of the tank 1.

[0031] The rotating shaft 4 is provided with multiple connected sleeves 401 in the axial direction inside the tank body 1. The sleeves 401 and the rotating shaft 4 are arranged in a cross shape. Multiple connecting rods 701 are fixed on one side of the scraper 7. The connecting rods 701 slide against the sleeves 401.

[0032] The sleeve 401 is equipped with a rotating double-ended lead screw 13. The end of the double-ended lead screw 13 is threadedly connected to the connecting rod 701. The rotating shaft 4 is equipped with a pull rod 9. A gear 14 is fixed in the middle of the double-ended lead screw 13. Multiple racks 901 are fixed on the pull rod 9. The racks 901 mesh with the gears 14.

[0033] By driving the pull rod 9 to move, the gear 14 and the double-ended lead screw 13 are driven to rotate, which in turn drives the scrapers 7 on both sides to move relative to each other.

[0034] Konjac flour is added to tank 1, and warm water is added. The rotating shaft 4 is used to stir the mixture so that the konjac flour and water are fully mixed and in contact, causing the konjac flour to expand into a paste. Then, the material is discharged. The drive rod 9 is used to open the scrapers 7 on both sides of the rotating shaft 4 and press them against the inner wall of tank 1, thereby scraping off the material adhering to the inner wall during discharge.

[0035] The position of the scraper 7 is indirectly controlled by the movement of the lever 9, thus automating the cleaning process, improving production efficiency, and ensuring product quality. Furthermore, this device is also applicable to other materials requiring similar processing, demonstrating versatility and flexibility.

[0036] The threads at both ends of the double-ended lead screw 13 turn in opposite directions. The rotation of the double-ended lead screw 13 can drive the connecting rods 701 at both ends to move relative to each other, so that the scraper 7 abuts against the inner wall of the tank 1.

[0037] Preferably, a connecting pipe 101 is provided on one side of the tank body 1, and the connecting pipe 101 is used to connect to the vacuum pump;

[0038] The bottom of the tank 1 is provided with a discharge port 102, and a three-way valve 8 is provided on the discharge port 102 for switching between discharge and cleaning operations.

[0039] During the puffing and mixing process, the tank 1 is evacuated by a vacuum pump to achieve the best puffing effect. After puffing is completed, the three-way valve 8 is opened to allow the material to flow from the outlet 102 to the discharge pipe. After the material is discharged, the three-way valve 8 is switched to allow the cleaned material to be discharged from the cleaning pipe.

[0040] Vacuum processing significantly improves the puffing effect of konjac flour, making it more uniform and delicate. The three-way valve design allows for quick switching between discharge and washing operations, improving work efficiency. The scraper 7 design effectively reduces material residue, and combined with the washing system, ensures the hygiene standards of the equipment. This improvement not only enhances the functionality of the device but also improves production efficiency and product quality, making it a highly practical design for production processes requiring high-quality puffing.

[0041] Preferably, a heating device 3 is provided on the outer periphery of the tank body 1;

[0042] Heating device 3 is a resistance heating device or a hot circulating water heating device.

[0043] Resistance heating device: Heats the tank by generating heat through the passage of electric current through a resistive material. This heating method has a fast response time and precise temperature control, making it suitable for scenarios requiring rapid heating or precise temperature control.

[0044] Hot circulating water heating device: This device uses circulating hot water as the heat transfer medium to heat the tank. This method provides uniform heating with minimal temperature fluctuations, making it suitable for processes requiring long-term maintenance of stable temperatures.

[0045] Proper heating can significantly improve the puffing effect of konjac flour, making it more uniform and delicate. Whether using resistance heating or hot water circulation heating, precise temperature control can be achieved to meet different process requirements. The two heating methods can be flexibly selected according to actual production conditions, increasing the equipment's applicability and operational flexibility. Combined with vacuum treatment, a three-way valve, and an automated cleaning system using scraper 7, the cleanliness of the equipment's interior is ensured, improving production hygiene standards.

[0046] Preferably, the cover plate 2 is provided with a feed inlet 201 and a motor bracket 202, and a motor 5 is fixed on the motor bracket 202. The motor 5 is connected to the rotating shaft 4 for transmission through the transmission structure 6.

[0047] The cover plate 2 has a mounting base 203 in the middle. The boss 402 at the end of the cover plate 2 abuts against the mounting base 203 through a bearing. A pressure plate 204 is fixed on the mounting base 203. The pressure plate 204 is used to fix the bearing.

[0048] In this example, the transmission structure 6 consists of a sprocket and a chain. The sprocket is fixed to the ends of the motor 5 and the shaft 4, respectively, and the sprockets are connected by a chain for transmission.

[0049] The sprocket and chain drive structure is simple and efficient, reducing energy loss and improving work efficiency while ensuring power transmission. A well-designed mounting base and pressure plate ensure stable operation of the shaft 4 and bearings, reducing equipment failure rates.

[0050] Preferably, an upper positioning sleeve 11 and a lower positioning sleeve 12 are fixed at both ends of the rotating shaft 4, and the two ends of the pull rod 9 inside the rotating shaft 4 move against the upper positioning sleeve 11 and the lower positioning sleeve 12 respectively.

[0051] A locking device 10 is fixed on the upper positioning sleeve 11, and the pull rod 9 slides within the locking device 10.

[0052] The locking device 10 is a clamp-type structure, which is tightened with bolts to clamp the pull rod 9, thereby fixing it. The two ends of the pull rod 9 are slidably positioned by the upper positioning sleeve 11 and the lower positioning sleeve 12.

[0053] The upper positioning sleeve 11 and the lower positioning sleeve 12 are fixed at both ends of the rotating shaft 4, respectively, to provide guidance and support for the sliding of the pull rod 9 within it. They ensure that the pull rod 9 can move smoothly within the rotating shaft 4, avoiding deviation or jamming.

[0054] The locking device 10 is fixed to the upper positioning sleeve 11 and adopts a clamp-type structure design. The pull rod 9 passes through the locking device 10 and is clamped and fixed by bolts. The main function of the locking device 10 is to clamp the pull rod 9 with the clamp, thereby fixing it when needed and preventing it from moving or loosening accidentally.

[0055] Preferably, the rotating shaft 4 has a groove, the pull rod 9 slides against the groove, and limit blocks are provided on both sides of the pull rod 9, with the gear 14 located in the limit blocks.

[0056] The pivot 4 has a special groove inside to guide and support the sliding of the pull rod 9. This design not only improves the smoothness of the pull rod 9's movement but also reduces friction and extends the service life of the components.

[0057] Gear 14 is located inside the limiting block and is fixed on the pull rod 9. It is located between the limiting blocks, which ensures that the meshing between gear 14 and rack 901 is more precise and stable.

[0058] With this structure, the gear 14 can rotate smoothly under the drive of the pull rod 9, thereby driving the double-ended lead screw 13 to rotate, and thus controlling the movement of the scraper 7.

[0059] Preferably, the scraper 7 matches the contour of the inner wall of the tank 1. The scraper 7 fits more closely against the inner wall of the tank 1.

[0060] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
