Description

Technical Field

[0001] This utility model relates to the field of puffed food processing technology, specifically a single-screw puffing machine for puffed food processing. Background Technology

[0002] Puffed foods are foods made from grains, potatoes, or beans as the main raw materials, which are puffed up by baking, frying, microwaving, or extrusion, resulting in a significant increase in volume and a certain degree of crispness. The single-screw extruder is an important piece of equipment in the puffed food production process. The single-screw extruder for puffed food processing is a processing equipment with a single screw as its core structure. During the extrusion of the puffed food raw materials by the single screw, the raw materials are heated, thereby realizing the puffing of the puffed food raw materials and finally producing the corresponding puffed food.

[0003] In existing single-screw extruders for processing puffed food, the puffed food raw materials are mixed and then enter the interior of the extrusion chamber. The single screw then heats the puffed food raw materials during the extrusion process, and then they are extruded through the extrusion plate. They then come into contact with the rotating shearing blades to achieve the shearing of the puffed food. The shearing unit is connected to the support of the puffing chamber outlet by bolts.

[0004] This type of single-screw extruder for processing puffed food has some problems. For example, the shear chamber is connected by bolts, which makes it inconvenient to install and disassemble the shear chamber. When the extrusion plate needs to be replaced, the shear chamber must be removed first, which is a cumbersome process and does not facilitate the quick replacement of the extrusion plate, thus affecting the ease of use for personnel. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a single-screw extruder for processing puffed food, which can realize the rapid and stable opening and closing of the shear chamber cover and the shear chamber, facilitate the replacement of the extrusion plate, and at the same time enable the centralized collection of puffed food, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-screw extruder for processing puffed food, including an extrusion chamber, a feeding chamber at the upper end of the extrusion chamber, and a shearing support mechanism;

[0007] The shearing support mechanism includes a shearing chamber cover, a shearing chamber, a first support, a second support, a locking handle, a pin, a slide groove, and a locking port. The front end of the shearing chamber is fixedly connected to the rear end of the outer surface of the puffing chamber. The upper end of the shearing chamber is hinged to the shearing chamber cover via evenly distributed hinges. The right end of the shearing chamber cover is fixedly connected to evenly distributed first supports. The right end of each first support is fixedly connected to a locking shaft. The right end of the shearing chamber is fixedly connected to evenly distributed second supports. The right end of each second support is fixedly connected to a pin. The outer surface of each pin is slidably connected to the slide groove at the lower end of the vertically adjacent locking handle. The upper end of each locking handle is provided with a locking port, which is installed in conjunction with the vertically adjacent locking shaft. This mechanism enables the shearing chamber cover and shearing chamber to open and close quickly and stably, facilitating the replacement of the extrusion plate and the centralized collection of puffed food.

[0008] Furthermore, the puffing chamber is rotatably connected to a rotating shaft, and the outer surface of the rotating shaft is provided with a spiral blade. The rear end of the puffing chamber is connected to an extrusion plate by evenly distributed bolts for spiral extrusion of puffed food.

[0009] Furthermore, a control box is provided on the right side of the puffing hopper, and a controller is installed inside the control box. The input terminal of the controller is electrically connected to an external power source to control various electrical appliances.

[0010] Furthermore, a drive chamber is provided at the front end of the puffing chamber, and the front end of the rotating shaft extends into the interior of the drive chamber. A driven gear is fixedly connected to the front end of the rotating shaft. A second motor is provided at the lower end of the front surface of the drive chamber. A drive gear is fixedly connected to the rear end of the output shaft of the second motor. The drive gear and the driven gear are meshed and connected. The input end of the second motor is electrically connected to the output end of the controller to provide driving force for the spiral extrusion of the puffed food.

[0011] Furthermore, the outer surface of the puffing chamber is provided with uniformly distributed heating chambers, and each heating chamber is equipped with a heater. The input end of each heater is electrically connected to the output end of the controller to provide heat for the puffing of the puffed food raw materials.

[0012] Furthermore, a motor is provided at the rear end of the shearing chamber cover. A rotating shaft is fixedly connected to the front end of the output shaft of the motor, and a connecting plate is fixedly connected to the front end of the rotating shaft. Evenly distributed shearing blades are fixedly connected to the middle of the connecting plate. The shearing blades are installed in conjunction with the extrusion plate. The input end of the motor is electrically connected to the output end of the controller to realize the shearing of the extruded puffed food.

[0013] Furthermore, a rotating column is rotatably connected inside the feeding hopper, a stirring rack is fixedly connected to the upper end of the outer surface of the rotating column, a spiral blade is fixedly connected to the lower end of the outer surface of the rotating column, a motor is installed at the upper end of the feeding hopper, the lower end of the output shaft of the motor is fixedly connected to the upper end of the rotating column, and the input end of the motor is electrically connected to the output end of the controller to perform mixing and spiral conveying of puffed food raw materials.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This single-screw extruder for processing puffed food has the following advantages:

[0015] The hinge provides support for the opening and closing of the shear chamber cover and the shear chamber. At the same time, after the locking shaft enters the locking port, the locking handle moves downward under its own weight, so that the locking shaft reaches the upper end of the locking port and the pins reach the upper end of the corresponding slide grooves. The shear chamber vertically limits the locking handle to prevent the locking handle from rotating, thereby realizing the rapid and stable locking and opening of the relative position of the shear chamber cover and the shear chamber. This facilitates the replacement of the extrusion plate and the centralized collection of puffed food, which is convenient for subsequent processing of puffed food. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a single screw extruder for processing puffed food, including an extrusion chamber 1, a feeding chamber 2 at the upper end of the extrusion chamber 1, a control box 18 on the right side of the extrusion chamber 1, a controller 19 inside the control box 18, the input end of the controller 19 being electrically connected to an external power supply, and also including a shearing support mechanism 3.

[0023] Shearing support mechanism 3: It includes a shearing chamber cover 31, a shearing chamber 32, a first support 33, a second support 34, a locking handle 35, a pin 36, a sliding groove 37, and a locking port 38. The front end of the shearing chamber 32 is fixedly connected to the rear end of the outer surface of the puffing chamber 1. The upper end of the shearing chamber 32 is hinged to the shearing chamber cover 31 by evenly distributed hinges 12. The right end of the shearing chamber cover 31 is fixedly connected to evenly distributed supports 33. The right end of each support 33 is fixedly connected to a locking shaft. The right end of the shearing chamber 32 is fixedly connected to evenly distributed supports 34. The right end of each support 34 is fixedly connected to a pin 36. The outer surface of each pin 36 is slidably connected to the interior of the sliding groove 37 at the lower end of the vertically adjacent locking handle 35. The upper end of each locking handle 35 is provided with a locking port 38. The locking port 38 is connected to the vertically adjacent locking handle 35. The shear chamber cover 31 is flipped to the right and installed in conjunction with the adjacent locking shaft. The shear chamber cover 31 is then fastened to the upper end of the shear chamber 32, thereby aligning the central axes of the extrusion plate 8 and the rotating shaft 9. Then, the locking handle 35 is rotated from bottom to top. The locking handle 35 rotates around the central axis of the corresponding pin 36. When the locking shafts are all inside the corresponding locking openings 38, the rotation of the locking handle 35 is stopped, and the holding of the locking handle 35 is ended. The locking handle 35 moves down under its own weight, and the locking shaft slides to the upper end of the locking opening 38. The pins 36 slide relative to the corresponding slide grooves 37. The pins 36 reach the upper end of the slide grooves 37. The shear chamber 32 limits the locking handle 35 to prevent it from rotating, thereby achieving a rapid and stable locking of the relative position of the shear chamber cover 31 and the shear chamber 32.

[0024] The puffing chamber 1 is internally connected to a rotating shaft 4. The outer surface of the rotating shaft 4 is provided with a spiral blade 5. The pitch of the spiral blade 5 in the middle is smaller than the pitch of the front and rear ends of the spiral blade 5. The rear end of the puffing chamber 1 is connected to an extrusion plate 8 by evenly distributed bolts. According to the type of puffed food to be produced, an extrusion plate 8 with a corresponding shape of through hole is selected, and then the extrusion plate 8 is connected to the rear end of the puffing chamber 1 by bolts. The front end of the puffing chamber 1 is provided with a drive chamber 13. The front end of the rotating shaft 4 extends into the interior of the drive chamber 13. The front end of the rotating shaft 4 is fixedly connected to a driven gear. The lower end of the front surface of the drive chamber 13 is provided with a motor 15. The rear end of the output shaft of the motor 15 is fixedly connected to a drive gear 14. The drive gear 14 and the driven gear are meshed and connected. The input end of the motor 15 is electrically connected to the output end of the controller 19.

[0025] Wherein: The outer surface of the puffing chamber 1 is provided with uniformly distributed heating chambers 6, and each heating chamber 6 is provided with a heater 7. The input end of the heater 7 is electrically connected to the output end of the controller 19. The controller 19 enables the motor 15 to operate. The output shaft of the motor 15 rotates, which drives the drive gear 14 to rotate, which in turn drives the driven gear to rotate. The driven gear rotates, which drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates, which drives the spiral blade 5 to rotate. Because the pitch in the middle of the spiral blade 5 is smaller than the pitch at the front and rear ends of the spiral blade 5, the conveying speed of the puffed food raw material decreases when it reaches the middle of the puffing chamber 1 during the movement of the puffing food raw material in the cavity. At the same time, it is accompanied by strong shearing, kneading and friction. Meanwhile, the controller 19 enables the heater 7 to operate, which provides heat for the puffing of the puffed food raw material. The puffed food raw material is extruded through the extrusion plate 8.

[0026] Among them: a motor 11 is provided at the rear end of the shearing chamber cover 31. A rotating shaft 9 is fixedly connected to the front end of the output shaft of the motor 11. A connecting plate is fixedly connected to the front end of the rotating shaft 9. A uniformly distributed shearing blade 10 is fixedly connected to the middle of the connecting plate. The shearing blade 10 is installed in conjunction with the extrusion plate 8. The input end of the motor 11 is electrically connected to the output end of the controller 19. The controller 19 realizes the operation of the motor 11. The rotation of the output shaft of the motor 11 drives the connecting plate to rotate, which in turn drives the uniformly distributed shearing blade 10 to rotate, thereby realizing the cutting of the extruded puffed food. The cut puffed food is discharged centrally under the action of the collection hopper at the lower end of the shearing chamber 32.

[0027] The feeding hopper 2 is internally connected to a rotating column 16. A stirring rack is fixedly connected to the upper end of the outer surface of the rotating column 16, and a spiral blade is fixedly connected to the lower end of the outer surface of the rotating column 16. A motor 17 is installed at the upper end of the feeding hopper 2. The lower end of the output shaft of the motor 17 is fixedly connected to the upper end of the rotating column 16. The input end of the motor 17 is electrically connected to the output end of the controller 19. The raw materials corresponding to the puffed food are added into the feeding hopper 2. At the same time, the controller 19 enables the motor 17 to operate. The output shaft of the motor 17 rotates, which drives the rotating column 16 to rotate. The rotation of the rotating column 16 drives the stirring rack to rotate, thereby realizing the mixing of the puffed food raw materials. At the same time, the rotation of the rotating column 16 drives the spiral blade to rotate, realizing the spiral conveying of the mixed puffed food raw materials. The mixed puffed food raw materials enter the interior of the puffing hopper 1.

[0028] The working principle of the single-screw extruder for processing puffed food provided by this utility model is as follows: During operation, the operator first places the puffing chamber 1, the feeding chamber 2, and other mechanisms stably in a horizontal working area. After stable placement, the operator first selects the extrusion plate 8 with the corresponding through-hole shape according to the type of puffed food to be produced. Then, the extrusion plate 8 is bolted to the rear end of the puffing chamber 1. Next, the operator flips the shearing chamber cover 31 to the right, causing it to snap onto the upper end of the shearing chamber 32, thus aligning the central axis of the extrusion plate 8 and the rotating shaft 9. Then, the operator rotates the locking handle 35 from bottom to top, with the locking handle 35 rotating around the corresponding pin. When the central axis of shaft 36 rotates, and all locking shafts enter the corresponding locking ports 38, the operator stops rotating the locking handle 35 and releases their grip on it. The locking handle 35 moves downwards under its own weight, and the locking shaft slides to the upper end of the locking port 38. All pins 36 slide relative to their corresponding sliding grooves 37, reaching the upper end of the sliding grooves 37. The shearing chamber 32 limits the locking handle 35, preventing it from rotating, thus achieving rapid and stable locking of the relative positions of the shearing chamber cover 31 and the shearing chamber 32. Then, the operator adds the corresponding raw materials for the puffed food into the feeding chamber 2, while the controller 19... The controller 19 activates motor 17, whose output shaft rotates to drive rotating column 16, which in turn rotates the mixing rack, thus mixing the puffed food ingredients. Simultaneously, rotating column 16 drives spiral blade 2, conveying the mixed puffed food ingredients into the puffing chamber 1. The controller 19 then activates motor 15, whose output shaft rotates to drive drive gear 14, which in turn drives driven gear 4, which in turn drives rotating shaft 4, which in turn drives spiral blade 5. Because the pitch of the spiral blade 5 in the middle is less than... The pitch of the spiral blade 5 at both ends affects the movement of the puffed food raw material within the cavity. When it reaches the middle of the puffing chamber 1, the conveying speed decreases, accompanied by strong shearing, kneading, and friction. Simultaneously, the controller 19 activates the heater 7 to provide heat for the puffing of the puffed food raw material. The puffed food raw material is then extruded through the extrusion plate 8. At the same time, the controller 19 activates the motor 11. The output shaft of the motor 11 rotates, driving the connecting disc to rotate, which in turn drives the evenly distributed shearing blades 10 to rotate, thus cutting the extruded puffed food. The cut puffed food is then collected and discharged by the collection hopper at the lower end of the shearing chamber 32.

[0029] It is worth noting that the controller 19 disclosed in the above embodiments controls the operation of the heater 7, motor 11, motor 2 15 and motor 3 17 using methods commonly used in the prior art.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
