Description

Technical Field

[0001] The present invention relates to the technical field of puffed food processing, and specifically provides a two-color extrusion device for puffed food processing. Background Art

[0002] Puffed food is a kind of snack food mainly made of grains, potatoes or beans, etc., and is made by puffing processes such as baking, frying, microwave or extrusion, etc., with a significantly increased volume and a certain puffing degree. Usually, after adding a small amount of water to the starchy raw material and mixing evenly, it is continuously pressurized and heated by an extruder, so that the raw material is extruded from the nozzle and rapidly expanded, and then cut appropriately according to needs and seasoned to make it.

[0003] There are still the following problems in the processing of two-color puffed food: 1. In the process of processing two-color puffed food, the two processing channels for traditional production of two-color puffed food are generally placed in parallel. The parallel processing channels will form a relatively long pipeline, reducing the fluidity of the two-color puffed food raw material in the processing channel, and then the phenomenon of condensation and blockage of the two-color puffed food raw material will occur. At this time, it is necessary to waste a certain amount of time for dredging, which will affect the processing efficiency of two-color puffed food.

[0004] 2. In the process of processing two-color puffed food, after the two-color puffed food raw materials of different colors are fed and discharged through the two processing pipelines, the two-color puffed food raw materials of the two colors will gather together. Traditionally, the pressure of the two-color extruder is generally used to mix and bond the gathered two-color puffed food raw materials, and then the phenomenon of loose bonding will occur, thus affecting the processing quality of two-color puffed food.

[0005] Therefore, in order to avoid affecting the processing efficiency and processing quality of two-color puffed food, the present invention provides a two-color extrusion device for puffed food processing. Summary of the Invention

Detailed implementation mode

[0031] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention in conjunction with the attached drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Refer to Figure 1 , an extrusion device for processing two-color puffed food, including a feeding mechanism 1, the left end face of the feeding mechanism 1 is connected to a two-color puffing machine, a discharging mechanism 2 is arranged on the right side of the feeding mechanism 1, and two groups are arranged below the feeding mechanism 1 and one group is arranged below the discharging mechanism 2 for supporting the feeding mechanism 1 and the discharging mechanism 2.

[0033] Refer to Figure 1 , Figure 2 and Figure 3, the feeding mechanism 1 includes two circular pipes 11. The left sides of the two circular pipes 11 are connected to a two-color puffing machine. The right sides of the two circular pipes 11 are placed crosswise and commonly fixedly installed with a communicating placement pipe 12. The diameter of the placement pipe 12 gradually decreases from left to right, and the right end face of the placement pipe 12 is fixedly installed with a communicating annular pipe 13. A heating rack 14 with an annular structure is arranged on the outer side wall of the annular pipe 13 near one end of the placement pipe 12. A mixing assembly 15 for mixing two-color puffing food raw materials is arranged in the placement pipe 12. A moving assembly 16 for controlling the mixing assembly 15 is also arranged on the placement pipe 12. A driving assembly 17 for controlling the movement of the moving assembly 16 is also arranged on the annular pipe 13.

[0034] In the original state, first, the two-color puffing machine is used to make puffing food raw materials of different colors enter the two circular pipes 11 respectively in a threaded feeding manner, and at the same time, the fed two-color puffing food raw materials enter the mixing assembly 15. After entering the mixing assembly 15, the driving assembly 17 is used to make the moving assembly 16 drive the mixing assembly 15 to extrude and mix the puffing food raw materials of different colors, so that the puffing food raw materials of different colors are extruded and mixed together, avoiding poor adhesion and affecting the processing quality of two-color puffing food. The heating rack 14 arranged on the annular pipe 13 can further heat the mixed two-color puffing food raw materials, further enhancing the adhesion of the two-color puffing food raw materials. And through the cross-set two-in-one circular pipes 11, it also prevents the problem of reduced fluidity caused by the long pipes formed by the traditional parallel processing channels, and then the two-color puffing food raw materials will condense and block. At this time, a certain amount of time needs to be wasted for dredging, which will affect the processing efficiency of two-color puffing food.

[0035] Refer to Figure 3 , Figure 4 and Figure 6 , the mixing assembly 15 includes a first annular plate 151 fixedly installed on the left side of the inner side wall of the placement pipe 12, and a second annular plate 152 is also fixedly installed on the right side of the inner side wall of the placement pipe 12. One end of the second annular plate 152 close to the first annular plate 151 is evenly connected in a circumferential direction by hinged arc-shaped swing plates 153. A conical structure with a gradually decreasing diameter from left to right is formed between the multiple swing plates 153. The right end face of the first annular plate 151 is fixedly installed with limit plates 154 corresponding to the swing plates 153 one by one. A placement groove is opened at one end of the limit plate 154 close to the center of the first annular plate 151. The placement groove is fixedly connected to the side wall of the swing plate 153 through a first spring rod 155. A flexible bag body 156 located inside the swing plate 153 is fixedly installed between the first annular plate 151 and the second annular plate 152.

[0036] After the two-color puffing machine uses the threaded feed port to make the fed two-color puffed food raw materials enter the circular pipe 11, at this time (as Figure 3 shown), under the action of the first spring rod 155, a plurality of swing plates 153 are driven to contact the side wall of the limiting plate 154, so that the left ends of the plurality of swing plates 153 are in an open state with a large diameter. Under the action of the two-color puffing machine, the two-color puffed food raw materials enter the flexible bags 156 on the first annular plate 151 and the second annular plate 152 through the two circular pipes 11 at the same time. After the two-color puffed food raw materials enter the flexible bags 156 at the same time, the moving component 16 is arranged to keep the opening of the swing plate 153 in a reciprocating extrusion state, so as to extrude and mix the puffed food raw materials of different colors, so that the puffed food raw materials of different colors are extruded and mixed together, avoiding poor adhesion and affecting the processing quality of the two-color puffed food.

[0037] Refer to Figure 3 , the moving component 16 includes rectangular through grooves symmetrically opened on the front and rear sides of the placing pipe 12. A push plate 161 is slidably arranged in the rectangular through grooves. One end of the push plate 161 located in the placing pipe 12 is fixedly installed with an annular sleeve plate 162 in a conical structure. The inner side wall of the annular sleeve plate 162 is in contact with the outer side walls of the plurality of swing plates 153. And the inner side wall of the annular sleeve plate 162 is evenly provided with semi-circular grooves at the end in contact with the swing plate 153. Rolling beads for reducing friction are arranged in the semi-circular grooves in a rolling manner. The front and rear side walls of the placing pipe 12 are fixedly installed with structural plates 163 in a U-shaped structure. Moving grooves are opened on the opposite surfaces of the horizontal sections of the front and rear two structural plates 163. The push plate 161 is slidably arranged in the moving grooves. A moving plate 164 is arranged on the horizontal section on the right side of the structural plate 163 in a sliding connection manner. The left end surface of the moving plate 164 is fixedly connected with the push plate 161. A moving spring is fixedly connected between the push plate 161 and the horizontal section on the right side of the structural plate 163.

[0038] Refer to Figure 2 , the driving component 17 includes a U-shaped plate 171 with an open bottom fixedly installed on the right sides of the front and rear two moving plates 164. A first motor fixedly installed on the right side of the heating rack 14 on the annular pipe 13. The output shaft of the first motor is fixedly installed with a cam 172 for controlling the movement of the U-shaped plate 171.

[0039] After the raw materials of the two-color puffed food enter the flexible bag body 156 simultaneously under the action of the two-color puffing machine, start the first motor. The first motor drives the rotating cam 172 to drive the U-shaped plate 171 to move, so that the moving plate 164 pushes the push plate 161 to move leftward in the rectangular through groove. The push plate 161 drives the annular sleeve plate 162 to move on the swing plate 153. By arranging rolling beads on the inner side wall of the annular sleeve plate 162, the friction can be reduced, so that the annular sleeve plate 162 can move smoothly on the swing plate 153. During the movement, a plurality of swing plates 153 can be quickly contracted inward simultaneously, and extrude the raw materials of the two-color puffed food in the flexible bag body 156, so that the raw materials of the two-color puffed food in the flexible bag body 156 are quickly pressed and bonded. After the cam 172 rotates one week, under the action of the moving spring, the moving plate 164 drives the right end surface of the U-shaped plate 171 to always contact the cam 172.

[0040] Refer to Figure 2 , the discharging mechanism 2 includes a flexible conical discharging pipe 21 fixedly installed on the right end surface of the annular pipe 13. The right end surface of the conical discharging pipe 21 is fixedly installed with an annular block 22 connected in communication. The right end surface of the annular block 22 is detachably provided with an extrusion nozzle 23 by means of threaded connection. The outlet shapes of the right sides of the plurality of extrusion nozzles 23 are different, and an extrusion assembly 24 for controlling the rapid discharging of the raw materials of the two-color puffed food after mixing is arranged on the conical discharging pipe 21. A clamping assembly 25 is further arranged on the extrusion assembly.

[0041] First, quickly replace the extrusion nozzles 23 with different outlet shapes according to actual needs. When the raw materials of the two-color puffed food after mixing enter the conical discharging pipe 21 simultaneously, by the cooperation of the arranged clamping assembly 25 and extrusion assembly 24, the extrusion assembly 24 can make the raw materials of the two-color puffed food after mixing in the conical discharging pipe 21 be quickly discharged, avoiding the phenomenon that the raw materials of the two-color puffed food cause condensation and blockage of the conical discharging pipe 21, thereby improving the processing efficiency of the two-color puffed food.

[0042] Refer to Figure 3 , Figure 5 and Figure 7, the extrusion assembly 24 includes mounting plates 241 in a U-shaped structure symmetrically and fixedly installed on the front and rear sides of the conical discharge pipe 21. The horizontal section of the mounting plate 241 is inclined and parallel to the side wall of the conical discharge pipe 21. Displacement grooves are provided on the opposite surfaces of the horizontal sections of the front and rear mounting plates 241. A moving block 243 is slidably connected in the displacement groove through a return spring 242. One end of the moving block 243 close to the conical discharge pipe 21 is fixedly installed with an arc-shaped block 244. One end of the arc-shaped block 244 close to the conical discharge pipe 21 is fixedly installed with an arc-shaped extrusion plate 246 through a plurality of second spring rods 245. Vertical plates 247 are fixedly installed on the lower end surfaces of the front and rear moving blocks 243. The two vertical plates 247 are fixedly connected through a connecting plate 248. A threaded rod 249 that cooperates with the clamping assembly 25 is rotatably arranged between the support blocks 31 on the annular pipe 13 and the annular block 22. The support block 31 on the annular pipe 13 is fixedly installed with an intermittent motor through a motor base, and one end of the intermittent motor is fixedly connected to the threaded rod 249.

[0043] When the extrusion nozzle 23 is replaced according to actual needs and the mixed two-color puffed food raw materials enter the conical discharge pipe 21 at the same time, at this time, the clamping assembly 25 and the threaded rod 249 are in a cooperative state, and the moving block 243 is located at the leftmost side in the displacement groove. Next, start the intermittent motor to rotate. Under the limitation of the clamping assembly 25, the threaded rod 249 makes the connecting plate 248 drive the vertical plate 247 to move to the right. The vertical plate 247 drives the moving block 243 to slowly move to the right in the displacement groove. During the movement, under the action of the second spring rod 245, the arc-shaped extrusion plate 246 extrudes the conical discharge pipe 21, so that the mixed two-color puffed food raw materials in the conical discharge pipe 21 are quickly discharged. When the threaded rod 249 makes the vertical plate 247 drive the moving block 243 to be located at the rightmost side in the moving groove, at this time, the clamping assembly 25 and the threaded rod 249 are no longer in a cooperative state, and under the action of the return spring 242, the moving block 243 drives the vertical plate 247 to quickly return to the original state, and thus will not affect the mixed two-color puffed food raw materials in the conical discharge pipe 21. Repeating the above steps can complete the quick discharge of the mixed two-color puffed food raw materials.

[0044] Refer to Figure 7 and Figure 8, the clamping assembly 25 includes a circular through groove opened at the center position of the connecting plate 248. Sliding grooves connected to the circular through groove are symmetrically opened on the front and rear sides of the connecting plate 248. A rectangular block 251 is slidably connected in the sliding groove. One end of the rectangular block 251 close to the center of the threaded rod 249 is fixedly installed with an arc-shaped clamping plate 253 through a square block 252. Thread grooves matching the threaded part of the threaded rod 249 are opened on the inner side walls of the two clamping plates 253. A clamping block 254 is fixedly installed on the clamping plate 253 at the rear side. A clamping groove corresponding to the clamping block 254 is opened on the clamping plate 253 at the front side. One end of the clamping block 254 close to the groove is in an eight-shaped structure. A limiting block 255 slidably connected to the square block 252 is fixedly installed at one end of the inner side wall of the circular through groove away from the rectangular block 251. The limiting block 255 and the rectangular block 251 are fixedly connected by a compression spring 256. Electromagnets 257 with the same magnetism are fixedly installed in the sliding groove and at one end of the rectangular block 251 away from the compression spring 256.

[0045] In the original state, the electromagnets 257 are energized. During the energization process of the electromagnets 257 with the same magnetism, the two electromagnets 257 are in a repulsive state, so that the rectangular block 251 on the electromagnet 257 compresses the compression spring 256 on the limiting block 255. The rectangular block 251 drives the square block 252 to slide on the limiting block 255, and then the square block 252 drives the front and rear clamping plates 253 to move synchronously inward. During the clamping process, the eight-shaped clamping block 254 provided can play a role in guiding and limiting, so that the clamping block 254 can be quickly clamped into the clamping groove. At this time, the thread groove on the inner wall of the clamping plate 253 is matched with the threaded rod 249, which can facilitate the rapid discharge of the mixed two-color expanded food raw materials in the conical discharge pipe 21. When the thread groove on the inner wall of the clamping plate 253 does not need to be matched with the threaded rod 249, the electromagnets 257 are powered off. Under the action of the compression spring 256, the square block 252 on the rectangular block 251 can drive the front and rear clamping plates 253 to move synchronously outward.

[0046] The supporting mechanism 3 includes supporting blocks 31 arranged below the placing pipe 12, the annular pipe 13 and the annular block 22. Semi-circular plates 32 for supporting the placing pipe 12, the annular pipe 13 and the annular block 22 are fixedly installed on the tops of the supporting blocks 31. Anti-slip pads are fixedly installed on the inner side walls of the semi-circular plates 32.

[0047] The semi-circular plates 32 arranged on the supporting blocks 31 can play a role in supporting and limiting the placing pipe 12, the annular pipe 13 and the annular block 22. The anti-slip pads arranged on the semi-circular plates 32 can increase the friction to avoid the sliding of the placing pipe 12, the annular pipe 13 and the annular block 22, which will affect the processing of the two-color expanded food.

[0048] During specific operation:

[0049] First step: First, quickly replace the extrusion nozzle 23 with different outlet shapes according to actual needs. After replacement, use the set two-color puffing machine to make puffing food raw materials of different colors enter the two circular pipes 11 respectively in a threaded feeding manner, and at the same time make the fed two-color puffing food raw materials enter the mixing component 15.

[0050] Second step: At this time, start the first motor. The first motor makes the rotating cam 172 drive the U-shaped plate 171 to move, and then makes the moving plate 164 push the push plate 161 to move leftward in the rectangular through groove. The push plate 161 drives the annular sleeve plate 162 to move on the swing plate 153, so that the annular sleeve plate 162 can move smoothly on the swing plate 153. During the movement, multiple swing plates 153 can be quickly and simultaneously contracted inward, and the two-color puffing food raw materials in the flexible bag body 156 are squeezed, so that the two-color puffing food raw materials in the flexible bag body 156 are quickly pressed and bonded. After the cam 172 rotates one week, under the action of the moving spring, the right end face of the moving plate 164 drives the U-shaped plate 171 to always be in contact with the cam 172, so that the opening of the swing plate 153 is always in a reciprocating extrusion state, and the puffing food raw materials of different colors are extruded and mixed.

[0051] Third step: At this time, under the action of the two-color puffing machine, the mixed two-color puffing food raw materials enter the conical discharge pipe 21 at the same time. At this time, the clamping component 25 and the threaded rod 249 are in a matching state, and the moving block 243 is located at the leftmost side in the displacement groove. Next, start the intermittent motor to rotate. Under the limit of the clamping component 25, the threaded rod 249 makes the connecting plate 248 drive the vertical plate 247 to move to the right. The vertical plate 247 drives the moving block 243 to move slowly to the right in the displacement groove. During the movement, under the action of the second spring rod 245, the arc-shaped pressing plate 246 presses the conical discharge pipe 21, so that the mixed two-color puffing food raw materials in the conical discharge pipe 21 are quickly discharged. When the threaded rod 249 makes the vertical plate 247 drive the moving block 243 to be located at the rightmost side in the moving groove, at this time, the clamping component 25 and the threaded rod 249 are no longer in a matching state, and under the action of the return spring 242, the moving block 243 drives the vertical plate 247 to quickly return to the original state, so as not to affect the mixed two-color puffing food raw materials in the conical discharge pipe 21. Repeating the above steps can complete the quick discharge of the mixed two-color puffing food raw materials.
