Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a twin-screw extruder for producing self-cooking dough. Background Art

[0002] The twin-screw extruder for self-cooking dough production is a device specially used for producing self-cooking dough. Its working principle is to mix, knead and heat the materials (usually flour and water) in the extruder through the rotation and extrusion of two screws to form dough. The advantages of the twin-screw extruder are that it can realize automated production, improve production efficiency, and adjust the thickness and taste of the dough as needed. At the same time, due to the high temperature and high pressure during the extrusion process, it can also kill bacteria and microorganisms to ensure the hygiene and safety of the dough.

[0003] When using a twin-screw extruder to produce self-cooking dough, high-quality flour needs to be mixed with water, then left to rest, and then processed into dough through an extruder, and finally cut, collected and packaged. However, in order to fully extrude and knead the dough, the existing twin-screw extruders use longer screws, which require a larger power motor to provide power, resulting in increased production costs. In addition, the twin-screw extruders need to be regularly maintained and serviced. The existing twin-screw extruders are inconvenient to disassemble and are not conducive to maintenance. For this reason, we propose a twin-screw extruder for the production of self-cooking dough. Utility Model Content

In addition, the existing twin-screw extruders are inconvenient to disassemble and are not conducive to maintenance.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

A motor shaft is arranged inside the motor 10, and one end of the motor shaft is movably inserted into the reducer 9. Two gear shafts 11 are movably inserted on the reducer 9, and a gear set is arranged inside the reducer 9. The motor shaft is connected to the two gear shafts 11 through the gear set.

[0030] Two docking plates 12 are fixedly installed on one side of the two gear shafts 11, four connecting shafts 13 are fixedly plugged on the two docking plates 12 on the two gear shafts 11, and docking wheels 14 are movably plugged on the eight connecting shafts 13. Connecting rods 8 are fixedly installed on one end of the two screw rods 3, and the two connecting rods 8 are movably plugged between the two docking plates 12 on the two gear shafts 11, and the eight docking wheels 14 are respectively arranged on both sides of the two connecting rods 8.

[0031] An extrusion column 15 is provided inside one end of the extrusion tube 2, and a plurality of support plates 16 are fixedly installed on the outer surface of the extrusion column 15. The plurality of support plates 16 are movably abutted against the inner wall of the extrusion tube 2. A mounting groove 17 is provided at one end of the extrusion tube 2, and a sleeve 18 is movably installed inside the mounting groove 17. The extrusion column 15 is movably inserted into the interior of the sleeve 18, and a dividing knife 27 is fixedly installed at one end of the extrusion column 15 by screws.

[0032] Two bolt connection blocks 20 are fixedly installed on the extrusion tube 2, and the two bolt connection blocks 20 are movably inserted with second fixing bolts 23.

[0035] It should be noted that the utility model is a twin-screw extruder for self-cooking dough production. When in use, first, place the device on a horizontal ground, and connect an external power supply to a controller 28. Then, the user needs to control the controller 28 to energize the motor 10 and a plurality of heating coils 25.
