Description

Technical Field

[0001] The present invention belongs to the field of mixing and stirring devices, and particularly relates to a mixing and stirring device for puffed food raw materials. Background Art

[0002] Puffed foods are mainly made from grains, tubers or beans, etc., and are made by puffing processes such as baking, frying, microwave or extrusion, etc., to have a significantly increased volume and a certain puffing degree, and are a kind of crispy, fragrant and variously flavored snack foods.

[0003] In the production process of puffed foods, various raw materials need to be mixed. Among all the raw materials, some raw materials are inevitably agglomerated due to moisture absorption. During the mixing process, these agglomerated raw materials are not easily dispersed for mixing; the conventional method generally screens these agglomerated raw materials first, and adopts a method of roller pressing and heating to disperse the agglomerated raw materials, and then pours them into the mixing and stirring device for mixing.

[0004] The above method requires the raw materials to be first put into a screening device for screening, which not only increases the processing steps of the raw materials, but also directly roller presses the agglomerated raw materials. The water content of the raw materials inside the agglomerated raw materials is relatively large, and it is easy to stick to the roller pressing device after roller pressing, thus causing another cleaning step, and the steps are cumbersome.

[0008] Further technical solution: The material distributing assembly includes a filter plate and a second motor. The filter plate is rotatably connected to the rectangular frame. A guiding hole is communicated at the position where the connecting sleeve is connected to the rectangular frame. The second motor is fixedly connected to the outer wall of the connecting sleeve, and the output shaft of the second motor is fixedly connected to the rotation central axis of the rectangular frame.

[0009] Further technical solution: The feeding mechanism includes a third motor and a first electric heating grid plate. A support frame is fixedly connected to the bottom of the mixing drum. The support frame is fixedly connected with a third motor, and a first electric heating grid plate is spirally arranged along the length direction on the output shaft of the third motor.

[0010] Further technical solution: The material scattering mechanism includes a second electric heating grid plate, a spring and a gear sleeve; The second electric heating grid plate is vertically slidably connected to the inner wall of the mixing drum. A mixing drum air flow circulation system is fixedly connected to the sleeve pipe. A spring is arranged between the second electric heating grid plate and the spring baffle. A gear sleeve is fixedly connected to the bottom of the crushing disc. Meshing teeth are arranged on the upper end surface of the second electric heating grid plate, and the gear sleeve meshes with the meshing teeth on the upper end surface of the second electric heating grid plate.

[0011] Further technical solution: The hot air mechanism includes an air guide cylinder, an air duct, a fourth motor, a gear disc and a bevel gear; The air guide cylinder is fixedly connected to the upper end surface of the mixing drum. A plurality of air ducts are rotatably connected to the side wall of the air guide cylinder. A fourth motor is fixedly connected to the top of the air guide cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The sleeve drives all the stirring mechanisms to mix and stir the materials; during this process, the material distributing component in the stirring mechanism guides the agglomerated materials into the sleeve. Then, the feeding mechanism heats and conveys the agglomerated materials upward. The materials with smaller volume in the sleeve fall into the shoveling plates, and the materials with smaller volume are discharged from the back of the shoveling plates to the outside of the sleeve. At the same time, the sleeve drives all the shoveling plates to shovel the materials at the bottom of the mixing drum upward, so as to continuously mix the materials accumulated at the bottom of the mixing drum with the upper materials; 2. The fourth motor drives the toothed disc to rotate. Under the cooperation of the toothed disc and all the bevel gears, all the air guide pipes rotate synchronously, and the blowing directions of all the air guide pipes are adjusted to be opposite to the rotation direction of the crushing disc. The air guide pipes blow the materials on all the crushing discs to roll. At this time, the agglomerated materials continuously rub against the entrance of the strip holes, so as to continuously heat and differentiate the surface of the materials. While crushing the materials, the internal moisture of the agglomerated materials is relatively large. This method can avoid the situation that the materials will stick to the surface of the crushing disc when directly crushed; 3. When a large amount of materials are blocked and accumulated on the second electric heating grid plate, adjust the blowing directions of all the air guide pipes to be vertically downward, so that the wind power of all the air guide pipes is concentrated downward. All the strip holes on the crushing disc guide the hot air. Under the rotation of the crushing disc, the hot air in the air guide pipes uniformly dries the materials accumulated on the second electric heating grid plate; 4. When the sleeve drives the connecting sleeve to rotate, under the oblique thrust of the filter plate, the materials with larger agglomeration are pushed into the sleeve by the filter plate through the material guiding holes. The materials with smaller volume pass through the filter plate, and under the guiding action of the material guiding plate, the materials with smaller volume are mixed with the lower materials; adjusting the angle between the filter plate and the rectangular frame can change the collection speed of the materials with larger agglomeration. When there are more materials in the crushing disc or the second electric heating grid plate, the situation that the materials in the crushing disc or the second electric heating grid plate are blocked can be avoided by reducing the angle between the filter plate and the rectangular frame.

Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0025] As Figures 1-7As shown in the figure, a mixing and stirring device for puffed food raw materials provided by the present invention includes a stirring cylinder 1. The upper and lower ends of the stirring cylinder 1 are respectively communicated with a feeding trough 11 and a discharging trough 12. Cut-off valves are arranged on both the feeding trough 11 and the discharging trough 12. A sleeve 13 is rotatably connected to the center position of the inner bottom surface of the stirring cylinder 1. A driving assembly 2 for driving the sleeve 13 to rotate is arranged outside the stirring cylinder 1. A plurality of stirring mechanisms 3 are connected to the outer wall of the sleeve 13. The stirring mechanisms 3 are used for mixing and stirring the materials in the stirring cylinder 1. A material distributing assembly 4 is arranged in the stirring mechanisms 3. The material distributing assembly 4 can introduce the agglomerated materials into the sleeve 13. A feeding mechanism 5 is arranged in the sleeve 13. The feeding mechanism 5 can push the agglomerated materials upward and heat them. A plurality of shoveling plates 10 are communicated with the position of the sleeve 13 near the bottom. The shoveling plates 10 are inclined relative to the horizontal plane, and a filter screen is arranged at the position of the shoveling plates 10 close to the bottom surface of the stirring cylinder 1; The upper end of the sleeve 13 is fixedly connected with a crushing plate 14. A plurality of strip-shaped holes 15 are obliquely arranged on the bottom surface of the crushing plate 14. A hot air mechanism 7 is arranged at the top of the stirring cylinder 1. The hot air mechanism 7 can perform hot air treatment on the materials on the strip-shaped holes 15 from the upper side of the crushing plate 14, and the hot air mechanism 7 can change the blowing angle. An air flow circulation system 8 is arranged between the hot air mechanism 7 and the stirring cylinder 1; A material scattering mechanism 6 is vertically slidably connected to the inner wall of the stirring cylinder 1. The material scattering mechanism 6 can oscillate and heat the agglomerated materials.

[0026] In this embodiment, all the materials are poured into the stirring cylinder 1 through the feeding trough 11, and then the driving assembly 2 is started. The driving assembly 2 drives the sleeve 13 to rotate, and the sleeve 13 drives all the stirring mechanisms 3 to mix and stir the materials; during this process, the material distributing assembly 4 in the stirring mechanism 3 introduces the agglomerated materials into the inside of the sleeve 13, and then the feeding mechanism 5 heats and conveys the agglomerated materials upward. The materials with smaller volume in the sleeve 13 fall into the shoveling plates 10, and the materials with smaller volume are discharged from the back of the shoveling plates 10 to the outside of the sleeve 13. At the same time, the sleeve 13 drives all the shoveling plates 10 to shovel up the materials at the bottom of the stirring cylinder 1, so as to continuously mix the materials accumulated at the bottom of the stirring cylinder 1 with the upper materials; After the agglomerated materials are conveyed to the crushing plate 14, the agglomerated materials perform circular motion along with the crushing plate 14. During this process, the hot air mechanism 7 applies a reverse hot air force to the materials. The agglomerated materials roll relative to the surface of the crushing plate 14. At this time, the agglomerated materials continuously rub against the entrance of the strip-shaped holes 15, so as to continuously heat and differentiate the surface of the materials. While crushing the materials, the internal moisture of the agglomerated materials is relatively large. This method can avoid the situation that directly crushing the materials will cause the materials to stick to the surface of the crushing plate 14; When the material is reduced to a certain volume, the material falls from the strip-shaped hole 15 onto the bulk material mechanism 6. The bulk material mechanism 6 can oscillate and heat-differentiate the agglomerated material. Finally, the agglomerated material falls into the mixing drum 1 and is further mixed and stirred with the remaining materials.

[0027] As Figure 6 shown, a mixing and stirring device for puffed food raw materials provided by the present invention. The stirring mechanism 3 includes a connecting sleeve 31, a rectangular frame 32, and a guiding plate 33. The connecting sleeve 31 is fixedly connected to the side wall of the sleeve 13, and the connecting sleeve 31 is in communication with the sleeve 13. The connecting sleeve 31 is fixedly connected with a rectangular frame 32. Both sides of the rectangular frame 32 are fixedly connected with a plurality of guiding plates 33. All the guiding plates 33 are inclined relative to the vertical direction.

[0028] In this embodiment, the sleeve 13 drives all the rectangular frames 32 to rotate. All the guiding plates 33 in the rectangular frames 32 mix and stir the materials. Under the guiding action of all the guiding plates 33, all the materials at different heights in the mixing drum 1 are continuously mixed.

[0029] As Figure 6 shown, a mixing and stirring device for puffed food raw materials provided by the present invention. The material distribution component 4 includes a filter plate 41 and a second motor 42. The filter plate 41 is rotatably connected to the rectangular frame 32. A guiding hole 17 is provided at the position where the connecting sleeve 31 is connected to the rectangular frame 32. The second motor 42 is fixedly connected to the outer wall of the connecting sleeve 31. The output shaft of the second motor 42 is fixedly connected to the rotation central axis of the rectangular frame 32.

[0030] In this embodiment, the second motor 42 drives the filter plate 41 to rotate, so that the filter plate 41 maintains a certain angle with respect to the rectangular frame 32 in the vertical direction. When the sleeve 13 drives the connecting sleeve 31 to rotate, under the oblique thrust of the filter plate 41, the materials with larger agglomeration are pushed into the sleeve 13 by the filter plate 41 through the guiding hole 17. The materials with smaller volume pass through the filter plate 41, and under the guiding action of the guiding plates 33, the materials with smaller volume are mixed with the lower materials. Adjusting the angle between the filter plate 41 and the rectangular frame 32 can change the collection speed of the materials with larger agglomeration. When there is more material in the crushing tray 14 or the bulk material mechanism 6, the blockage of the material in the crushing tray 14 or the bulk material mechanism 6 can be avoided by reducing the angle between the filter plate 41 and the rectangular frame 32.

[0031] As Figure 4As shown in the figure, a mixing and stirring device for puffed food raw materials provided by the present invention, the feeding mechanism 5 includes a third motor 51 and a first electric heating grid plate 52. The bottom of the stirring cylinder 1 is fixedly connected with a support frame 16, the support frame 16 is fixedly connected with a third motor 51, and the output shaft of the third motor 51 is spirally provided with a first electric heating grid plate 52 along the length direction.

[0032] In this embodiment, when the third motor 51 is started, the third motor 51 drives the first electric heating grid plate 52 to rotate. The first electric heating grid plate 52 pushes the agglomerated materials upward, and the smaller-volume materials fall downward until they are discharged from the back of the shoveling plate 10.

[0033] As Figure 5 shown in the figure, a mixing and stirring device for puffed food raw materials provided by the present invention, the material scattering mechanism 6 includes a second electric heating grid plate 61, a spring 62 and a gear sleeve 63; The second electric heating grid plate 61 is vertically slidably connected to the inner wall of the stirring cylinder 1. An air circulation system 8 of the stirring cylinder 1 is fixedly connected to the sleeve 13. A spring 62 is arranged between the second electric heating grid plate 61 and the spring baffle 9. The bottom of the crushing plate 14 is fixedly connected with a gear sleeve 63. The upper end surface of the second electric heating grid plate 61 is provided with meshing teeth, and the gear sleeve 63 meshes with the meshing teeth on the upper end surface of the second electric heating grid plate 61.

[0034] In this embodiment, when the crushing plate 14 rotates, under the cooperation of the gear sleeve 63 and the meshing teeth on the upper end surface of the second electric heating grid plate 61, the gear sleeve 63 pushes the second electric heating grid plate 61 downward. The second electric heating grid plate 61 moves downward along the inner wall of the stirring cylinder 1. At this time, the spring 62 is compressed. Under the elastic thrust of the spring 62, the second electric heating grid plate 61 vibrates vertically reciprocally. When the materials fall from the strip-shaped holes 15 onto the second electric heating grid plate 61, the second electric heating grid plate 61 heats and differentiates the materials and evenly scatters the materials.

[0035] As Figure 7 shown in the figure, a mixing and stirring device for puffed food raw materials provided by the present invention, the hot air mechanism 7 includes an air guide cylinder 71, an air guide pipe 72, a fourth motor 73, a gear disk 74 and a bevel gear 75; The air guide cylinder 71 is fixedly connected to the upper end surface of the stirring cylinder 1. The side wall of the air guide cylinder 71 is rotatably connected with a plurality of air guide pipes 72. The top of the air guide cylinder 71 is fixedly connected with a fourth motor 73. The output shaft of the fourth motor 73 is fixedly connected with a gear disk 74. The end of each air guide pipe 72 is fixedly connected with a bevel gear 75, and the gear disk 74 meshes with all the bevel gears 75.

[0036] In this embodiment, the fourth motor 73 is started to rotate, and the fourth motor 73 drives the toothed disc 74 to rotate. Under the cooperation of the toothed disc 74 and all the bevel gears 75, all the air ducts 72 rotate synchronously, and the blowing directions of all the air ducts 72 are adjusted to be opposite to the rotation direction of the crushing plate 14. The air ducts 72 blow the materials on all the crushing plates 14 to roll, and at this time, the bonded materials are constantly rubbed against the entrance of the strip holes 15, so that the surface of the materials is continuously heated and decomposed; When the No. 2 electric heating mesh plate 61 is clogged and a lot of materials are piled up, the blowing direction of all the air ducts 72 is adjusted vertically downward, so that the wind force of all the air ducts 72 is concentrated downward, and all the bar holes 15 on the crushing plate 14 guide the hot air. Under the rotation of the crushing plate 14, the hot air in the air duct 72 evenly dries the materials piled up on the No. 2 electric heating mesh plate 61.

[0037] like Figure 2 As shown, a mixing and stirring device for puffed food raw materials provided by the present invention is provided, wherein the air circulation system 8 includes an air pump 81, an air pipe 82 and a filter box 83; An air pump 81 is fixedly connected to the upper end surface of the mixing drum 1, and a filter box 83 is connected to the side wall of the mixing drum 1. The filter box 83 is arranged at the lower side of the bulk material mechanism 6. An air pipe 82 is connected between the air pump 81, the air guide cylinder 71 and the filter box 83. A filter screen is arranged at the filter box 83, and activated carbon is arranged in the filter box 83.

[0038] In this embodiment, the air pump 81 is started, and the air pump 81 delivers wind to the air guide cylinder 71 . Meanwhile, the hot air in the mixing cylinder 1 is delivered to the air pump 81 after passing through the filter box 83 .

[0039] like Figure 4 As shown, a mixing and stirring device for puffed food raw materials provided by the present invention is provided, wherein the driving assembly 2 includes a first motor 21, a fixed shaft 22 and a gear transmission pair 23; The first motor 21 is fixedly connected to the bottom surface of the mixing drum 1 , a fixed shaft 22 is fixedly connected to the bottom of the sleeve 13 , and a gear transmission pair 23 is transmission-connected between the fixed shaft 22 and the first motor 21 .

[0040] In this embodiment, the first motor 21 is started, the first motor 21 drives the fixed shaft 22 to rotate through the gear transmission pair 23, and the fixed shaft 22 drives the sleeve 13 to rotate.

[0041] Working principle: All materials are poured into the mixing drum 1 through the feeding chute 11. Then, the driving assembly 2 is started. The driving assembly 2 drives the sleeve 13 to rotate, and the sleeve 13 drives all the stirring mechanisms 3 to mix and stir the materials. During this process, the feeding component 4 in the stirring mechanism 3 guides the agglomerated materials into the interior of the sleeve 13. Then, the feeding mechanism 5 heats and conveys upward the agglomerated materials. The materials with smaller volume in the sleeve 13 fall into the shoveling plate 10, and the materials with smaller volume are discharged from the back of the shoveling plate 10 to the outside of the sleeve 13. At the same time, the sleeve 13 drives all the shoveling plates 10 to shovel up the materials at the bottom of the mixing drum 1, so as to continuously mix the materials accumulated at the bottom of the mixing drum 1 with the upper materials. After the agglomerated materials are conveyed to the crushing plate 14, the agglomerated materials perform circular motion along with the crushing plate 14. During this process, the hot air mechanism 7 applies a reverse hot air force to the materials. The agglomerated materials roll relative to the surface of the crushing plate 14. At this time, the agglomerated materials continuously rub against the entrance of the strip-shaped holes 15, so as to continuously heat and differentiate the surface of the materials. While crushing the materials, the internal moisture of the agglomerated materials is relatively large. This method can avoid the situation that directly crushing the materials will cause the materials to stick to the surface of the crushing plate 14. When the materials are reduced to a certain volume, the materials fall from the strip-shaped holes 15 onto the scattering mechanism 6. The scattering mechanism 6 can oscillate and heat and differentiate the agglomerated materials. Finally, the agglomerated materials fall into the mixing drum 1 to be further mixed and stirred with the remaining materials.

[0042] Specifically, the second motor 42 drives the filter plate 41 to rotate, so that the filter plate 41 maintains a certain angle with respect to the rectangular frame 32 in the vertical direction. When the sleeve 13 drives the connecting sleeve 31 to rotate, under the oblique thrust of the filter plate 41, the agglomerated materials with larger size are pushed into the sleeve 13 by the filter plate 41 through the guide holes 17. The materials with smaller volume pass through the filter plate 41, and under the guiding action of the guide plate 33, the materials with smaller volume are mixed with the lower materials. Adjusting the angle between the filter plate 41 and the rectangular frame 32 can change the collection speed of the agglomerated materials with larger size. When there are more materials in the crushing plate 14 or the second electric heating grid plate 61, the materials in the crushing plate 14 or the second electric heating grid plate 61 can be prevented from being blocked by reducing the angle between the filter plate 41 and the rectangular frame 32. The fourth motor 73 drives the gear disk 74 to rotate. Under the cooperation of the gear disk 74 and all the bevel gears 75, all the air guide pipes 72 rotate synchronously. The blowing direction of all the air guide pipes 72 is adjusted to be opposite to the rotation direction of the crushing plate 14. The air guide pipes 72 blow the materials on all the crushing plates 14 to roll. At this time, the agglomerated materials continuously rub against the entrance of the strip-shaped holes 15, so as to continuously heat and differentiate the surface of the materials. When there is a lot of material blocked and accumulated on the second electric heating grid plate 61, adjust the blowing directions of all the air ducts 72 vertically downward, so that the wind power of all the air ducts 72 is concentrated downward. All the strip holes 15 on the crushing tray 14 guide the hot air. Under the rotation of the crushing tray 14, the hot air in the air duct 72 evenly dries the material accumulated on the second electric heating grid plate 61 with hot air.
