Description

Technical Field

[0001] This utility model relates to the field of puffing machine technology, specifically a food puffing machine with uniform heating function. Background Technology

[0002] Extrusion is a processing method in which raw materials are fed into an extruder through a screw extrusion mechanism. During this process, the screw propels the raw materials to flow in the axial direction. Under the action of friction between the screw, the barrel, and the material, the raw materials are strongly squeezed, stirred, and sheared, ultimately achieving the purpose of refining and homogenizing. Of course, the pressure and temperature inside the machine will also increase accordingly, causing the already crushed raw materials inside to be cooked, turning from powder to paste and being sprayed out from the discharge port of the extruder.

[0003] Current puffing machines all produce puffed food in a single, high-temperature process within a single barrel, which is prone to over-expansion. Over-expansion results in reduced nutritional value of the raw materials and affects the texture of the puffed product. Furthermore, uneven heating leads to inconsistent quality of the puffed products. Therefore, we have proposed a food puffing machine with a uniform heating function. Utility Model Content

[0004] Existing puffing machines all produce puffs through a single high-temperature, one-time process in a single barrel, which easily leads to over-puffing. Over-puffing results in less nutrient content in the raw materials and affects the taste of the puffed product. This invention provides a food puffing machine with uniform heating function, which can achieve heating in different sections and achieve uniform heating, thereby improving the practicality of the device and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A food puffing machine with uniform heating function includes a processing box, a feeding hopper connected to the top of the processing box, a connecting pipe tightly attached to one side of the processing box, and a discharge pipe connected to the lower end of the connecting pipe on the side away from the processing box; a second rotating shaft is coaxially arranged inside the connecting pipe, and the two ends of the second rotating shaft are rotatably connected to the ends of the connecting pipe and the processing box, respectively; a second motor is coaxially connected to one end of the second rotating shaft, and spiral blades are tightly attached to the outer wall of the second rotating shaft; several sets of outer covers are equidistantly connected to the outer wall of the connecting pipe, each set of outer covers consists of two and is symmetrically connected to the outer wall of the connecting pipe, and multiple heating wires are tightly attached to the outer wall of the connecting pipe inside the outer covers, and a temperature sensor is connected to the outer wall.

[0008] Optionally, gaskets may be provided between the connecting skirts of each set of outer covers.

[0009] Optionally, a first rotating shaft is symmetrically provided at the lower end of the feed hopper and rotatably connected thereto. A rotating roller is coaxially connected to the first rotating shaft. Multiple partitions are equidistantly connected along the circumferential direction on the outer wall of the rotating roller. The partitions on the two rotating rollers are staggered. One end of the first rotating shaft is connected to the drive device.

[0010] Optionally, the drive device includes a first motor, and gears are coaxially connected to one end of each of the two first rotating shafts.

[0020] Reference Figures 1 to 3 This utility model provides a technical solution: a food puffing machine with uniform heating function, including a processing box 6, and a feeding hopper 5 connected to the top of the processing box 6, such as... Figure 3 As shown, in order to facilitate the stable falling of raw materials in the feed hopper 5, a first rotating shaft 14 is symmetrically provided at the lower end of the feed hopper 5 and is rotatably connected thereto. A rotating roller 18 is coaxially connected to the first rotating shaft 14, and multiple partitions 17 are equidistantly connected along the circumferential direction on the outer wall of the rotating roller 18.

The two gears 16 mesh with each other and coaxially connect the first motor 2 and one end of the first rotating shaft 14. Under the drive of the first motor 2, the two first rotating shafts 14 can be driven to rotate in opposite directions, which in turn can drive the multiple partitions 17 on the two rotating rollers 18 to rotate alternately, thereby enabling the raw materials in the feed hopper 5 to be discharged quickly. At the same time, in order to protect the gears 16, a protective cover 1 is fixedly attached to the outer wall of the processing box 6. The gears 16 are located inside the protective cover 1, and the first motor 2 and the protective cover 1 are fixedly connected.

[0022] like Figure 3As shown, a connecting pipe 13 is fastened to one side of the processing box 6.

A second motor 4 is coaxially connected to one end of the second rotating shaft 15, and the second motor 4 is fastened to the outer wall of the processing box 6 through the motor base 3. Spiral blades 19 are fastened to the outer wall of the second rotating shaft 15.

[0023] like Figure 3 As shown, to achieve uniform heating of the device, several sets of outer covers 7 are equidistantly connected to the outer wall of the connecting pipe 13. In actual installation, each set of outer covers 7 consists of two units and is symmetrically connected to the outer wall of the connecting pipe 13. Multiple heating wires 23 are tightly fastened to the outer wall of the connecting pipe 13 located inside the outer cover 7, and a temperature sensor 24 is connected to the outer wall. Through the detection of the temperature sensor 24, the temperature at the heating wire 23 can be detected in real time, thereby ensuring temperature controllability. In addition, to improve the stability of the installation of the heating wire 23, multiple retainers 22 are tightly fastened to the outer wall of the connecting pipe 13. The heating wire 23 is connected in the retainer 22, and the multiple sets of heating wires 23 can achieve different temperature ranges, which greatly facilitates processing.

[0024] In summary, this food puffing machine with uniform heating function, during use, to further improve the heat insulation of the outer wall of the connecting pipe 13, heat insulation cotton 21 is tightly attached to the inner wall of the outer cover 7.
