Description

Technical Field

[0001] This utility model relates to the field of konjac flour production, specifically to a konjac flour mixing and stirring device. Background Technology

[0002] Traditional puffing tanks present several significant problems in the processing of konjac flour, primarily concerning cleaning difficulty and production efficiency. During puffing, the mixture of konjac flour and warm water tends to adhere to the inner wall of the tank. This adhesion not only leads to material waste but also increases the difficulty and time required for cleaning. Cleaning necessitates manual scraping or the use of high-pressure water guns, which is time-consuming, labor-intensive, and ineffective in completely removing all residues.

[0003] In traditional manufacturing processes, mixing and extrusion molding are typically performed as two separate steps. Materials need to be mixed in one tank before being transferred to another machine for extrusion molding. This separation results in intermediate material transfers and equipment changes, increasing production cycles and the need for manual intervention. Utility Model Content

Detailed Implementation

[0027] like Figures 1-6 As shown, a konjac flour mixing and stirring device includes an extrusion tank 1, a storage tank 2, a mixing tank 5, and an alkaline water tank 4; multiple extrusion tanks 1 are connected to the storage tank 2 through pipes and pumps, and the storage tank 2 and the alkaline water tank 4 are connected to the mixing tank 5 through pipes and a metering pump 3;

[0028] A relatively movable insert plate 510 is provided in the middle of the mixing tank 5, which divides the mixing tank 5 into a mixing chamber and an extrusion chamber. A rotating second main shaft 506 is provided in the mixing tank 5. A paddle 507 is fixed on the upper part of the second main shaft 506 and a spiral blade 508 is fixed on the lower part. The insert plate 510 is sealed against the second main shaft 506. The paddle 507 is located in the mixing chamber and the spiral blade 508 is located in the extrusion chamber. A perforated plate 509 is provided at the discharge port at the bottom of the mixing tank 5. The end of the second main shaft 506 abuts against the perforated plate 509 and rotates. The spiral blade 508 is located above the perforated plate 509.

[0029] Konjac flour is fed into puffing tank 1 and mixed with warm water for puffing. Multiple puffing tanks 1 are used alternately for puffing. The puffed konjac is then stored in storage tank 2. Alkali water tank 4 contains alkali water. The puffed konjac paste and alkali water are metered into mixing tank 5 via metering pump 3. In the upper mixing chamber, the mixture is stirred by paddles 507. Then, by opening the insert plate 510, the konjac enters the lower extrusion chamber. The rotating spiral blades 508 extrude the konjac through the perforated plate 509 to form vermicelli, which is then cooked and shaped. Multiple puffing tanks 1 alternately perform puffing and cleaning operations to ensure the storage amount of konjac in storage tank 2. Mixing tank 5, through upper mixing and lower extrusion, enables continuous production. This structure achieves efficient puffing, precise mixing, and continuous extrusion molding of konjac flour, suitable for industrial production of konjac vermicelli. In addition, the design of this device takes into account the needs of cleaning and maintenance, effectively improving production efficiency and product quality.

[0030] Preferably, the puffing tank 1 includes a first tank body 101, a first top cover 103 fixed on the first tank body 101, a heater 102 provided on the outer wall of the first tank body 101, a rotating first main shaft 105 provided inside the first tank body 101, scrapers 106 that move relative to each other on both sides of the first main shaft 105, the scrapers 106 abutting against the inner wall of the first tank body 101, and a three-way valve 107 provided at the discharge port at the bottom of the first tank body 101, the three-way valve 107 being connected to the sewage pipe and the storage tank 2 connecting pipe respectively.

[0031] The temperature during puffing is adjusted by heater 102. After puffing is completed, the material is discharged by connecting the storage tank 2 through the three-way valve 107. At the same time, the relatively moving scraper 106 is driven to abut against the inner wall of the first tank 101 to remove the material adhering to the inner wall. After the material is discharged, the three-way valve 107 switches to connect with the sewage pipe to clean the puffing tank 1.

[0032] Extrusion Process: Konjac flour and warm water are added to the first tank 101, and the mixture is stirred and extruded using heat provided by the heater 102. Discharge Operation: After extrusion, the three-way valve 107 is controlled to connect to the storage tank 2, thereby discharging the extruded material into the storage tank for later use. Cleaning Operation: To keep the equipment clean, when cleaning is required, the three-way valve 107 switches to connect to the drain pipe, and simultaneously drives the scraper 106 to move along the inner wall of the tank to remove residual material and discharge it.

[0033] This design not only improves production continuity and efficiency, but also simplifies the cleaning process and reduces downtime, making it suitable for industrial environments that require high-frequency, high-quality production of konjac products.

[0034] Preferably, a first motor 104 is fixedly mounted on one side of the first upper cover 103. The first motor 104 is connected to the first main shaft 105 for transmission through a transmission mechanism 108. The end of the first main shaft 105 rotates against the first upper cover 103 through a bearing 109.

[0035] The first motor 104 drives the first main shaft 105 to rotate through the transmission mechanism 108, which is either a sprocket and a chain, or a synchronous pulley and a synchronous belt.

[0036] Preferably, the first spindle 105 is provided with a plurality of connected sleeves 116, the sleeves 116 and the first spindle 105 are arranged in a cross shape, the sleeves 116 are provided with a rotating double-ended lead screw 114, the two ends of the sleeves 116 are provided with sliding connecting rods 117, the ends of the connecting rods 117 are connected to the scraper 106, and the two ends of the double-ended lead screw 114 are threadedly connected to the threaded holes 118 at the ends of the connecting rods 117.

[0037] The threads at both ends of the double-ended lead screw 114 turn in opposite directions. By rotating the double-ended lead screw 114, the connecting rods 117 on both sides and the scraper 106 can be moved relative to each other, so that the scraper 106 abuts against the inner wall of the first tank 101.

[0038] Through the coordinated design of the double-ended lead screw 114 and connecting rod 117, the scraper 106 can closely adhere to the inner wall of the first tank 101, effectively removing adhering materials and ensuring thorough cleaning. The mechanical structure design ensures the stability and reliability of equipment operation, reduces downtime, and improves production efficiency.

[0039] Preferably, a sliding pull rod 111 is provided inside the first main shaft 105, and a plurality of racks 115 are fixed on the pull rod 111. A gear 113 is fixed in the middle of the double-ended lead screw 114, and the gear 113 meshes with the racks 115.

[0040] The inner wall of the first main shaft 105 is provided with a groove, the pull rod 111 slides against the groove, and limit blocks are provided on both sides of the pull rod 111. The gear 113 is located between the limit blocks.

[0041] The first spindle 105 has positioning sleeves 110 fixed at both ends. The two ends of the pull rod 111 slide against the positioning sleeves 110. The upper positioning sleeve 110 is fixed with a locking mechanism 112. The end of the pull rod 111 is located in the locking mechanism 112. The locking mechanism 112 is used to lock and fix the pull rod 111.

[0042] The drive rod 111 moves up and down, which causes the rack 115 to drive the gear 113 to rotate, so that the double-ended lead screw 114 rotates and drives the scrapers 106 at both ends to move; the locking mechanism 112 is a clamp-type structure, which clamps the rod 111 by bolts, thereby fixing it.

[0043] The rotation of the double-ended lead screw 114 can be precisely controlled by the cooperation of the pull rod 111 and the rack 115, thereby flexibly adjusting the position of the scraper 106. The locking mechanism 112 makes the adjustment and fixing of the position of the pull rod 111 very convenient, facilitating daily maintenance and cleaning of the equipment. This design not only optimizes the mixing effect during the puffing process but also significantly improves cleaning efficiency, providing convenience for continuous production and maintenance.

The insert plate 510 abuts and seals against the second tank 501 and the second main shaft 506.

[0046] Preferably, a second motor 505 is fixedly mounted in the middle of the second upper cover 502, and the output shaft of the second motor 505 is connected to the second main shaft 506;
