Description

Technical Field

[0001] The invention relates to the field of vermicelli processing, and in particular to a raw material crushing and pulping device and method for producing soak-free potato vermicelli. Background Art

[0002] During the crushing and pulping process, the phenolic substances in potatoes are easily exposed to oxygen in the air and undergo oxidation reactions, resulting in browning, which not only affects the appearance of the product, but may also change its flavor and nutritional content. Traditional devices lack effective anti-oxidation measures and are unable to isolate the air or create a low-oxygen environment, resulting in obvious oxidation of potatoes within a short period of time after crushing. Although traditional crushing devices create a low-oxygen or oxygen-free environment by continuously injecting inert gas into the crushing chamber, in order to ensure that the entire cavity reaches a low-oxygen or oxygen-free environment, a large gas flow rate and a long time are often required, and a relatively large amount of gas is consumed. In addition, there is a certain hysteresis in the injection of inert gas into the crushing chamber, which cannot promptly prevent the oxidation reaction at the moment of crushing.

[0003] At the same time, the traditional crushing device uses a single cutter to crush potatoes. At this time, due to the lack of continuous squeezing force on the potatoes, the potatoes will be crushed unevenly, and some large particles or lumps that are not completely broken will affect the quality and efficiency of subsequent pulping. In addition, when the traditional crushing device crushes potatoes, due to the single cutting method of the cutter, for some irregularly shaped or large potatoes, the single rotating cutter may not be able to completely cover their surface, resulting in some areas not being fully crushed, and there are still large lumps, which require secondary crushing, increasing processing time and cost. At the same time, the movement of a single cutter is not conducive to the rapid flow and dispersion of materials in the crushing chamber, and it is easy to cause the material to accumulate locally in the crushing chamber, affecting the effect of the cutter on the material, and further reducing production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] refer to Figures 1 to 11 The raw material crushing and pulping device for producing soak-free potato vermicelli comprises a crushing chamber 2 arranged at the upper end of a pulping chamber 1, and also comprises: A feed pipe 7 is arranged at the upper end of the crushing chamber 2 and communicated with the crushing chamber 2; The driving mechanism 12 is connected to the crushing chamber 2 and includes an air chamber 16, a center plate 18, a top frame 19 and a plurality of extrusion crushing mechanisms 22. The center plate 18 is coaxially connected to the upper end of the crushing chamber 2 for rotation (refer to Figure 2 ), the top frame 19 is arranged above the center plate 18 and is fixedly connected to the pulping chamber 1, the air chamber 16 is coaxially rotatably connected to the top frame 19 and is fixedly connected to the center plate 18, and a plurality of extrusion and crushing mechanisms 22 are arranged in an array at equal angles along the circumferential direction of the air chamber 16; Each extrusion crushing mechanism 22 includes a wire seat 30, a power shaft 33, a hollow crushing cone 41 and a plurality of crushing knives 42. The wire seat 30 is slidably arranged at the upper end of the center plate 18. The power shaft 33 is rotatably connected to the wire seat 30. The hollow crushing cone 41 is coaxially fixedly connected to the power shaft 33 (refer to Figure 7 ), a plurality of crushing knives 42 are arranged in an array at equal angles outside the hollow crushing cone 41; The gas injection mechanism 47 is connected to the gas chamber 16 and introduces the inert gas into the gas chamber 16 (refer to Figure 1 ).

[0020] When the device is in operation, the cleaned potatoes fall into the crushing chamber 2 from the feed pipe 7, and then the driving mechanism 12 starts and drives the air chamber 16 to rotate (the specific process is described in detail later). During the rotation of the air chamber 16, the plurality of extrusion and crushing mechanisms 22 will reciprocate through the wire seat 30 respectively, and the wire seat 30 will drive the plurality of hollow crushing cones 41 to rotate through the power shaft 33 during the reciprocating movement. When the plurality of hollow crushing cones 41 rotate, they will squeeze and cut the potatoes in the crushing chamber 2, and the gas injection mechanism 47 will introduce the inert gas into the plurality of power shafts 33 through the air chamber 16, and the plurality of power shafts 33 will spray the inert gas through the plurality of crushing knives 42, so that the potatoes will always maintain a low oxygen or oxygen-free environment during the cutting process. The crushed potatoes will fall downward into the pulping chamber 1 for further processing.

[0021] In order to supplement the specific structure of the crushing chamber 2, the following features are also specifically provided: The crushing chamber 2 is provided with a central cone 4 and a tapered inclined block 5. The central cone 4 is wide at the bottom and narrow at the top and is coaxially fixed to the bottom plate of the crushing chamber 2 (refer to Figure 2 ), the tapered inclined block 5 is annular and coaxially fixed to the inner wall of the crushing chamber 2, the side where the tapered inclined block 5 and the central cone 4 are close is a crushing chamber that is narrow at the bottom and wide at the top, and a plurality of screening holes 6 are formed in an array at equal angles along the circumferential direction at the bottom of the crushing chamber 2. When the potatoes fall into the crushing chamber 2, the central cone 4 and the tapered inclined block 5 are combined to form a crushing chamber that is wide at the top and narrow at the bottom, so that the potatoes can continue to fall under the action of gravity during the cutting process, avoiding the potato from being retained during the crushing process.

[0022] In order to supplement the specific structure of the feed pipe 7, the following features are also specifically provided: The feed pipe 7 includes a pipe body 10, a transfer cover 8 and a blanking arc block 11. The pipe body 10 is coaxially fixedly connected to the top frame 19 (refer to Figure 6 ), the adapter cover 8 is coaxially fixedly connected to the lower end of the tube body 10, and the adapter cover 8 is formed with a plurality of blanking holes 9 at equal angles along the circumferential direction (reference Fig. 9 ), the arc block 11 is coaxially fixed to the lower end of the inner wall of the adapter cover 8. When the potatoes fall through the tube body 10, the potatoes will first hit the arc block 11, and then continue to fall through the plurality of drop holes 9, thereby realizing continuous feeding of potatoes.

[0023] In order to supplement the specific structure of the gas injection mechanism 47, the following features are also specifically provided: The gas injection mechanism 47 also includes a gas guide pipe 48, a gas disk 49, a transfer plate 50 and a plurality of gas introduction pipes 51. The plurality of gas introduction pipes 51 are arranged in an array at equal angles along the upper end of the gas chamber 16 (refer to Figure 2 ), the adapter plate 50 is coaxially arranged above the air chamber 16 and is fixedly connected to the upper ends of the plurality of air ducts 51 (refer to Figure 4), the gas disk 49 is fixedly connected to the top frame 19 and is rotatably connected to the adapter plate 50, one end of the air duct 51 is connected to the air chamber 16, and the other end is connected to the gas disk 49, one end of the air guide pipe 48 is connected to the gas disk 49, and the other end is connected to the output end of the air pump. When the air pump inputs the inert gas into the gas disk 49 through the air guide pipe 48, the inert gas will flow into the gas chamber 16 through the plurality of air ducts 51. Since the adapter plate 50 and the gas disk 49 are rotatably connected, the input of the inert gas will not be interrupted even if the gas chamber 16 rotates.

[0024] In order to drive the air chamber 16 to rotate, the following features are also specifically provided: The driving mechanism 12 also includes a driving motor 13, a driving gear 14 and a driving gear ring 15. The driving motor 13 is fixedly connected to the outer wall of the crushing chamber 2 through a motor frame (refer to Figure 3 ), the driving gear 14 is coaxially fixedly connected to the output end of the driving motor 13, and the driving ring gear 15 is coaxially fixedly connected to the lower end of the air chamber 16 and meshes with the driving gear 14. After the driving motor 13 is started, the driving motor 13 drives the driving ring gear 15 to rotate through the driving gear 14, and when the driving ring gear 15 rotates, it drives the air chamber 16 fixed thereto to rotate.

[0025] In order to drive the wire holder 30 to reciprocate, the following features are also specifically provided: The driving mechanism 12 further includes a positioning gear ring 20, which is coaxially fixed to the lower end of the outer edge of the top frame 19 (refer to Figure 4 ), the extrusion crushing mechanism 22 also includes a first gear 23, a first bevel tooth 24, a second bevel tooth 25, a first pulley 26, a second pulley 27, a thread sleeve 28, a reciprocating screw 29, a third bevel tooth 31 and a fourth bevel tooth 32. The first gear 23 is rotatably connected to the upper end of the air chamber 16 and meshes with the positioning gear ring 20 (refer to Figure 4 ), the first bevel gear 24 is rotatably arranged at the upper end of the inner wall of the air chamber 16 through the bevel gear rack, the first bevel gear 24 is coaxially fixedly connected to the first gear 23, the second bevel gear 25 is rotatably connected to the bevel gear rack and meshes with the first bevel gear 24, the thread sleeve 28 is rotatably connected to the inner wall of the air chamber 16 and is threadedly connected to the reciprocating screw rod 29 (reference Figure 3 ), the wire sleeve 28 is coaxially connected to the second pulley 27, the first pulley 26 is coaxially connected to the second bevel gear 25 and is connected to the second pulley 27 through a belt, and the third bevel gear 31 is rotatably connected to the wire seat 30 through the bevel gear rack and is coaxially connected to the power shaft 33 (reference Figure 5), the fourth bevel tooth 32 is rotatably connected to the bevel gear rack and meshes with the third bevel tooth 31, and one end of the reciprocating screw rod 29 close to the center of the air chamber 16 is fixedly connected to the screw seat 30. When the air chamber 16 rotates, the air chamber 16 will drive the first gear 23 to revolve along the positioning gear ring 20. At this time, the positioning gear ring 20 will drive the first gear 23 to rotate. The first gear 23 will drive the second bevel tooth 25 to rotate through the first bevel tooth 24. The second bevel tooth 25 will drive the second pulley 27 to rotate through the first pulley 26. The second pulley 27 will drive the reciprocating screw 29 to move through the wire sleeve 28. The reciprocating screw 29 will drive the wire seat 30 fixed thereto to move (as can be seen from the foregoing, the wire seat 30 is slidably connected to the center plate 18, so the wire seat 30 will reversely limit the reciprocating screw 29 to prevent the reciprocating screw 29 from rotating without moving). After the wire seat 30 moves, it will drive the hollow crushing cone 41 to move through the power shaft 33. During the movement of the hollow crushing cone 41, the potatoes in the crushing chamber will be squeezed and crushed, thereby reducing the difficulty of subsequent potato shredding.

[0026] In order to prevent the inert gas in the crushing chamber 2 from escaping during the movement of the wire holder 30, the following features are also specifically provided: The extrusion crushing mechanism 22 further includes a bellows 40, the two ends of which are fixedly connected to the center plate 18 and the middle portion of which is fixedly connected to the lower end of the wire seat 30 (see Figure 5 ). During the reciprocating movement of the wire seat 30, the corrugated cover 40 will deform along with the movement of the wire seat 30, thereby preventing the inert gas in the crushing chamber from escaping.

[0027] In order to drive the hollow crushing cone 41 to rotate during the reciprocating movement of the wire seat 30, the following features are also specifically provided: The driving mechanism 12 also includes a central gear ring 21, which is coaxially fixed to the lower end of the top frame 19 at the center of the circle through a gear seat (refer to Figure 6 The extrusion crushing mechanism 22 also includes a central shaft 35, a central sleeve 36, a central air pipe 17, a power bevel gear 37, a central bevel gear 38 and a central gear 39. The central shaft 35 is rotatably arranged above the central plate 18 through a shaft seat (refer to Figure 5 ), the center sleeve 36 is key-connected to the center shaft 35, the center sleeve 36 is coaxially fixedly connected to the fourth bevel gear 32, the center bevel gear 38 is coaxially fixedly connected to the end of the center shaft 35 away from the air chamber 16 through the bevel gear rack, the power bevel gear 37 is rotatably connected to the bevel gear rack and meshes with the center bevel gear 38, the center gear 39 is coaxially fixedly connected to the upper end of the power bevel gear 37 and meshes with the center gear ring 21, one end of the center air pipe 17 is fixedly connected to the wire seat 30 and communicated with the power shaft 33 (reference Figure 5 ), and the other end is slidably connected to the air chamber 16 (reference Figure 3 ), the power shaft 33 has a plurality of main air holes 34 arranged in an equiangular array along the circumferential direction (refer to Figure 5 ), each crushing knife 42 is formed with a secondary air hole 43 (refer to Figure 7 ). When the air chamber 16 rotates, the air chamber 16 will drive the center plate 18 connected thereto to rotate. When the center plate 18 rotates, it will drive the center gear 39 to revolve along the circumferential direction of the center gear ring 21. Because the center gear 39 and the center gear ring 21 are meshed, the center gear 39 will rotate at this time. After the center gear 39 rotates, it will drive the center bevel gear 38 to rotate through the power bevel gear 37. After the center bevel gear 38 rotates, it will drive the center sleeve 36 to rotate through the center shaft 35. After the center sleeve 36 rotates, it will drive the third bevel gear 31 to rotate through the fourth bevel gear 32. The third bevel gear 31 will drive the hollow crushing cone 41 to rotate through the power shaft 33, ensuring that the hollow crushing cone 41 can further shred the potatoes through a plurality of crushing knives 42.

[0028] At the same time, the inert gas will flow into the power shaft 33 through the central air pipe 17, and finally be ejected from the corresponding crushing knife 42 through the main air hole 34 and the auxiliary air hole 43, so as to achieve a low oxygen environment when cutting potatoes.

[0029] In order to improve the crushing effect of materials, the following features are also set: The extrusion and crushing mechanism 22 further includes an auxiliary cutter 44 and a push plate 46. The auxiliary cutter 44 is coaxially fixedly connected to the lower end of the hollow crushing cone 41. The auxiliary cutter 44 is formed with auxiliary air holes 45 connected to the power shaft 33 in an array of equal angles along the circumferential direction. The push plate 46 is rotatably connected to the lower end of the auxiliary cutter 44 and is slidably connected to the bottom plate of the crushing chamber 2. When the hollow crushing cone 41 rotates, the auxiliary cutter 44 can further cut and crush the potatoes falling on the bottom of the crushing chamber 2. At the same time, the auxiliary air holes 45 provide a low-oxygen environment for the auxiliary cutter 44 to cut, and the push plate 46 is used to smooth the potato pieces stuck on the screen holes 6 to prevent the blockage of several drop holes 9.

[0030] The operating method of the raw material crushing and pulping device for producing soak-free potato vermicelli also includes the following use steps: S1: The operator puts potatoes into the crushing chamber 2 through the feed pipe 7, and then starts the gas injection mechanism 47 to introduce inert gas into the gas chamber 16; S2: Then the driving mechanism 12 is started, and after the driving mechanism 12 is started, the air chamber 16 is driven to rotate, and after the air chamber 16 rotates, it is rotated along the circumferential direction of the crushing chamber 2 through a plurality of extrusion crushing mechanisms 22; S3: The squeezing and crushing mechanism 22 will squeeze and crush the potatoes during the rotation process; S4: The crushed potatoes fall down into the pulping chamber 1 for further processing.

[0031] The working principle of the device is that when potatoes fall into the crushing chamber 2, the central cone 4 and the tapered inclined block 5 are combined to form a crushing chamber which is wide at the top and narrow at the bottom, so that the potatoes can continue to fall under the action of gravity during the cutting process, thereby avoiding the potato from being retained during the crushing process.

[0032] After the driving motor 13 is started, the driving motor 13 will drive the air chamber 16 to rotate. When the air chamber 16 rotates, the wire seat 30 will reciprocate and drive the hollow crushing cone 41 to move. During the movement of the hollow crushing cone 41, the potatoes in the crushing chamber will be squeezed and crushed, reducing the difficulty of subsequent potato shredding. At the same time, the rotation of the air chamber 16 will also cause the power shaft 33 to drive the hollow crushing cone 41 to rotate, ensuring that the hollow crushing cone 41 can further shred the potatoes through a number of crushing knives 42. In this process, although there is a gap between two adjacent hollow crushing cones 41, the various movement modes of the hollow crushing cone 41 cooperate with each other (rotation along its own axis, revolution along the circumference of the crushing chamber 2, and reciprocating movement along the axis of the reciprocating screw rod 29), so that the falling potatoes will not be pushed all the time and cannot be crushed. That is, the potatoes will constantly change their position and posture during the falling process, and contact different parts of the hollow crushing cone 41, thereby increasing the chance of being crushed. Even if the potatoes are in the gap at a certain moment and are not directly crushed, they will soon come into contact with the hollow crushing cone 41 again and be crushed as the material flows as a whole.

[0033] At the same time, when the air pump inputs the inert gas into the air disk 49 through the air duct 48, the inert gas will pass through a number of air ducts 51 and flow into the air chamber 16. Since the adapter plate 50 and the air disk 49 are rotatably connected, the input of the inert gas will not be interrupted even if the air chamber 16 rotates. Then the inert gas will flow into the power shaft 33 through the central air pipe 17, and finally pass through the main air hole 34 and the auxiliary air hole 43 and then be ejected from the corresponding crushing knife 42, thereby achieving a low oxygen environment when cutting potatoes.

[0034] Finally, when the hollow crushing cone 41 rotates, the auxiliary cutter 44 can further cut and crush the potatoes falling on the bottom of the crushing chamber 2, while the auxiliary air hole 45 provides a low-oxygen environment for the auxiliary cutter 44 to cut, and the push plate 46 is used to smooth the potato pieces stuck on the screen holes 6 to prevent the clogging of some screen holes 6. After the crushing, the potato pieces will fall down into the pulping chamber 1 for further processing.

[0035] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
