Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a chopping and mixing device. Background Technology

[0002] Flour products account for a large share of the snack market and are generally packaged in small portions. However, during the cutting process, food processing equipment may not be able to precisely control the cut length, resulting in significant variations in length within the same batch. This affects the uniformity of adding seasonings during subsequent chopping. For example, longer pieces may have less seasoning, while shorter pieces may have too much, leading to inconsistent flavors. Furthermore, during chopping, seasonings and other ingredients may not be evenly distributed throughout the flour products. This could be due to factors such as the mixing method and speed of the chopping equipment, meaning some flour products may not have sufficient contact with the seasonings, affecting the overall texture. Therefore, this application provides a chopping device. Utility Model Content

[0038] Please see Figure 1-8 Flour products account for a large share of the snack market, and are generally packaged in small portions. However, during the cutting process, food processing equipment may not be able to precisely control the cutting length of the food, resulting in significant differences in length within the same batch. This affects the uniformity of the addition of auxiliary ingredients during subsequent chopping. For example, longer foods may have less seasoning, while shorter foods may have too much, leading to inconsistent product flavors. For instance, during chopping, auxiliary ingredients such as chili peppers and seasonings may not be evenly distributed in the flour products. This may be due to factors such as the mixing method and speed of the chopping equipment; some flour products may not have sufficient contact with the auxiliary ingredients, affecting the overall taste. Therefore, this application provides a chopping device, comprising a conveying trough 2 for conveying, a chopping component 1 combined with the conveying trough 2, and a conveying and mixing component 3 installed at the bottom of the chopping component 1, for processing the food to be processed.

[0039] The cutting assembly 1 includes a main body 11, the top of the main body 11 is inclined at a preset angle to one end of the conveying groove 2, and a cutting blade 12 is provided on the inner side of the main body 11, and the cutting blade 12 is driven by a motor to cut the food to be processed.

[0040] The conveying and mixing assembly 3 includes a frame 32, the top of which is disposed on the conveyor belt 31. A feeding port 34 is provided at one end of the conveyor belt 31 away from the main body 11. A mixing chamber 35 is provided below the feeding port 34 for mixing the food to be delivered.

[0041] The cutting component 1 includes a main body 11, the top of which is inclined at a preset angle to one end of the conveying trough 2. This preset angle can be adjusted according to actual production needs, and is generally suitable between 30° and 60°, such as 45°. This inclination helps the food to be processed to smoothly enter the main body 11 from the conveying trough 2 for cutting.

[0042] A cutting blade 12 is provided on the inner side of the main body 11, and the cutting blade 12 is driven by a motor to cut the food to be processed. The cutting blade 12 can be a circular blade, and the number of blades can be set according to the production scale and cutting requirements, for example, 3-5 blades. The motor can be a speed-regulating motor, and the cutting speed of the cutting blade 12 can be controlled by adjusting the speed of the motor to adapt to different types and textures of food to be processed. In order to ensure the cutting effect and service life of the cutting blade 12, the blade material can be made of high-hardness, high-strength alloy steel, and the blade surface is coated to improve the wear resistance and corrosion resistance of the blade.

[0043] The conveying and mixing assembly 3 includes a frame 32, the top of which is disposed on the conveyor belt 31. A feeding port 34 is provided at one end of the conveyor belt 31 away from the main body 11. A mixing chamber 35 is provided below the feeding port 34 for mixing the food to be processed.

[0044] The conveyor belt 31 can be a belt-type conveyor belt 31, and its surface can be provided with anti-slip texture to prevent the food to be processed from slipping during the conveying process. The conveying speed of the conveyor belt 31 can be adjusted by a speed regulating device to match the cutting speed of the chopping component 1.

[0045] The feeding port 34 can be designed as a funnel to facilitate the accurate addition of auxiliary materials such as chili peppers and seasonings into the mixing chamber 35. A metering device can be installed at the feeding port 34 to precisely control the amount of auxiliary materials added, ensuring that the amount of auxiliary materials added is consistent for each batch of products.

[0046] The mixing chamber 35 is equipped with a stirring paddle, which can be a propeller-type structure. The shape and number of its blades can be optimized according to the mixing effect. The stirring paddle is driven by a motor, which can be located outside the mixing chamber 35 and connected to the stirring paddle via a drive shaft. To make the mixing more uniform, baffles can be installed on the inner wall of the mixing chamber 35 to increase the contact opportunity between the auxiliary materials and the food to be processed.

[0047] Working principle

[0048] The food to be processed is conveyed through the conveyor trough 2 into the main body 11 of the cutting assembly 1. The motor drives the cutting blade 12 to cut the food into appropriate lengths. The cut food falls onto the conveyor belt 31 of the conveying and mixing assembly 3 and is conveyed to the feeding port 34 as the conveyor belt 31 runs. At this time, the amount of auxiliary materials added is precisely controlled by the metering device and added from the feeding port 34 into the mixing chamber 35. The mixing paddle in the mixing chamber 35 rotates under the drive of the motor, thoroughly mixing the food to be processed and the auxiliary materials, so that the auxiliary materials are evenly distributed in the food, and finally a product with a consistent taste is obtained.

[0049] By organically combining the conveying trough 2, the chopping component 1, and the conveying and mixing component 3, the problems of uneven addition of auxiliary materials and inconsistent product taste during food chopping in existing technologies are solved. The inclined setting and adjustable cutting speed of the chopping component 1 can ensure more precise cutting length of the food to be processed; the metering device and optimized mixing paddle design of the conveying and mixing component 3 can ensure uniform addition and thorough mixing of auxiliary materials, improving product quality and consistency of taste, and has high practical value and market promotion prospects.

[0050] A control box 33 is provided on one side of the mixing chamber 35 to control the rotation speed of the cutting tool 12.

[0051] The stirring chamber 35 includes a chamber 351, a separation tank 352 is installed inside the chamber 351, an inner cavity 353 is provided inside the separation tank 352, a through hole is provided at the center of the bottom of the inner cavity 353, and a positioning ring 356 is installed thereon.

[0052] A rotating shaft 358 is installed on the inner side of the positioning ring 356. The rotating shaft 358 has a plug hole 3511 at one end that passes through the through hole at the bottom of the separation barrel 352.

[0053] A drive unit 3510 is provided at the center of the bottom of the cavity 351, and the output shaft of the drive unit 3510 is adapted to the insertion hole 3511 at the bottom of the rotating shaft 358.

[0054] A control box 33 is located on one side of the mixing chamber 35. The main function of the control box 33 is to control the rotation speed of the cutting blade 12. The control box 33 integrates an advanced electronic control system, and the required rotation speed parameters can be input via the operation buttons on the control panel or the touch screen. For example, for harder flour products, the rotation speed of the cutting blade 12 can be increased to 2000 rpm; while for softer products, the speed can be reduced to 1500 rpm. The control box 33 also has a speed feedback adjustment function. It monitors the actual rotation speed of the cutting blade 12 in real time through sensors and compares it with the set value. If a deviation occurs, it can automatically adjust the power of the drive motor to ensure that the cutting blade 12 operates stably at the set speed.

[0055] The mixing chamber 35 includes a chamber 351, which provides a relatively enclosed space for the entire mixing process, effectively preventing material from splashing out. A separation tank 352 is installed inside the chamber 351. The function of the separation tank 352 is to isolate the material from other components inside the chamber 351, preventing the material from contaminating the chamber 351, and also facilitating centralized mixing of the material.

[0056] The inner side of the separating tank 352 is provided with an inner cavity 353, which is the main area for material mixing. A through hole is provided at the center of the bottom of the inner cavity 353, and a positioning ring 356 is installed thereon. The positioning ring 356 is made of high-strength engineering plastic, which has good wear resistance and corrosion resistance. Its inner diameter is precisely matched with the rotating shaft 358, providing stable support and positioning for the rotating shaft 358, ensuring that the rotating shaft 358 will not wobble or shift during high-speed rotation.

[0057] A rotating shaft 358 is installed inside the positioning ring 356. The rotating shaft 358 is a key component for driving the material to be stirred. The rotating shaft 358 is made of high-quality alloy steel and has undergone precision machining and heat treatment processes, giving it high strength and hardness. A insertion hole 3511 is provided at one end of the rotating shaft 358 that passes through the through hole at the bottom of the separation tank 352.

[0058] A drive unit 3510 is located at the center of the bottom of the cavity 351. The drive unit 3510 is typically a high-performance servo motor, and its output shaft is fitted with a insertion hole 3511 at the bottom of the rotating shaft 358. When the drive unit 3510 is activated, its output shaft inserts into the insertion hole 3511 of the rotating shaft 358, transmitting power to the rotating shaft 358 via a keyed or splined connection. This causes the rotating shaft 358 to rotate at high speed, thereby agitating the material in the inner cavity 353. During the installation of the rotating shaft 358 and the drive unit 3510, precise alignment can be ensured using locating pins or locating slots, guaranteeing efficient and stable power transmission.

[0059] Working principle

[0060] The food to be processed enters the chopping assembly 1 through the conveyor trough 2. The control box 33 precisely controls the rotation speed of the cutting blade 12 according to the characteristics of the food, cutting the food into appropriate lengths. The cut food falls onto the conveyor belt 31 of the conveying and mixing assembly 3, and then enters the inner cavity 353 of the mixing chamber 35 through the feeding port 34. The drive unit 3510 is started, and its output shaft drives the rotating shaft 358 to rotate. The rotating shaft 358 can be equipped with mixing blades and other mixing components to fully mix the food and added auxiliary materials in the inner cavity 353. The separation tank 352 and the positioning ring 356 ensure the stable operation of the rotating shaft 358, making the mixing process more uniform and efficient, thus solving the problems of uneven addition of auxiliary materials and inconsistent product taste in the existing chopping process.

[0061] The control box 33 precisely controls the rotation speed of the cutting blade 12, improving the accuracy of food cutting length and reducing uneven addition of auxiliary materials due to length differences. The unique structural design of the mixing chamber 35, including the separating tank 352, positioning ring 356, and rotating shaft 358, ensures the stable operation of the rotating shaft 358, allowing auxiliary materials to be evenly mixed with the food. This effectively improves the consistency of the product's taste and quality stability, resulting in significant economic benefits and promising market application prospects.

[0062] One or more stirring rods 367 bent at a preset angle are provided on the outer side of the rotating shaft 358. The stirring rods 367 are used to stir the food inside the loading separation tank 352.

[0063] A spraying assembly 359 is provided on the top of the rotating shaft 358 for auxiliary processing of the food to be processed.

[0064] The outer side of the separation barrel 352 is provided with a mirror-image hanging ear 354, and the inner side of the cavity 351 is provided with a slot 355 corresponding to the hanging ear 354, and the slot 355 is adapted to the hanging ear 354.

[0065] The spraying assembly 359 includes a ring 3591, the bottom center of which is adapted to the top of the rotating shaft 358. A filling cavity 3593 is provided on the inner side of the ring 3591, and a sealing groove 3594 is provided on the top of the filling cavity 3593 for sealing the filling cavity 3593 in conjunction with a sealing plate.

[0066] The outer side of the ring body 3591 is provided with injection holes 3592 in a ring array. The injection holes 3592 are connected to the inner side of the filling cavity 3593 and are used to discharge the auxiliary material to be sprayed.

[0067] The conveying trough 2 includes a trough body 21, and an adjustment component 22 is provided on the back of the trough body 21 and one side of the main body 11 for adjusting the angle of the trough body 21.

[0068] One or more stirring rods 367, bent at a preset angle, are provided on the outer side of the rotating shaft 358. These stirring rods 367 are used to stir the food loaded inside the separating tank 352. The preset angle can be adjusted according to actual stirring needs, and is generally suitable between 30° and 60°. For example, when set to 45°, the stirring rods 367 can more effectively agitate the food during rotation, increasing the contact area between the food and auxiliary materials. The number of stirring rods 367 can be selected according to the size of the separating tank 352 and the production scale. If the diameter of the separating tank 352 is small, 2-3 stirring rods 367 can be provided; if the diameter of the separating tank 352 is large, 4-6 stirring rods 367 can be provided. The stirring rods 367 are made of high-strength, corrosion-resistant stainless steel, with a smooth surface that does not easily adhere to food and auxiliary materials, making them easy to clean and maintain.

[0069] A spraying assembly 359 is provided on the top of the rotating shaft 358 for auxiliary processing of the food to be processed. The spraying assembly 359 can evenly spray the auxiliary materials during the mixing process, further improving the uniformity of mixing between the auxiliary materials and the food.

[0070] The outer side of the separator 352 is provided with mirror-image hanging ears 354, and the inner side of the cavity 351 is provided with a corresponding slot 355, which fits the hanging ears 354. This design allows the separator 352 to be securely installed inside the cavity 351, while also facilitating disassembly and cleaning. To install the separator 352, simply align the hanging ears 354 with the slot 355 and gently push it in; disassembly is done in the reverse order.

[0071] The spraying assembly 359 includes a ring 3591, the bottom center of which is fitted to the top of a rotating shaft 358, ensuring that the ring 3591 can rotate with the rotating shaft 358. A filling cavity 3593 is formed on the inner side of the ring 3591 for storing the excipients to be sprayed. A sealing groove 3594 is provided on the top of the filling cavity 3593 to cooperate with a sealing plate to seal the filling cavity 3593 and prevent excipient leakage. Spray holes 3592 are arranged in a ring array on the outer side of the ring 3591, communicating with the inner side of the filling cavity 3593 to discharge the excipients to be sprayed. When the rotating shaft 358 rotates, the ring 3591 rotates accordingly, using centrifugal force to evenly spray the excipients in the filling cavity 3593 onto the food through the spray holes 3592. The size and number of spray holes 3592 can be designed according to the spray volume and spray range of the auxiliary material. For example, for cases with a large spray volume, the diameter of the spray holes 3592 or the number of spray holes 3592 can be appropriately increased.

[0072] The conveying trough 2 includes a trough body 21. An adjustment component 22 is provided on the back of the trough body 21 and one side of the main body 11 for adjusting the angle of the trough body 21. The adjustment component 22 can be implemented using an electric push rod or a manual adjusting screw. By adjusting the angle of the trough body 21, the speed and angle at which the food to be processed enters the cutting component 1 can be controlled, thereby improving the accuracy and efficiency of cutting. For example, when it is necessary to speed up the food entry speed, the angle of the trough body 21 can be increased; when it is necessary to more precisely control the cutting length, the angle of the trough body 21 can be appropriately decreased.

[0073] The food to be processed enters the chopping assembly 1 through the conveying trough 2. The angle of the trough 21 of the conveying trough 2 is adjusted by the adjusting assembly 22, allowing the food to enter the chopping assembly 1 at a suitable speed and angle for cutting. The cut food falls into the separation tank 352 of the conveying and mixing assembly 3. The rotating shaft 358 rotates under the drive of the drive component 3510, and the stirring rod 367 installed on the outside of the rotating shaft 358 stirs the food. At the same time, the auxiliary materials are pre-loaded into the filling cavity 3593 of the spraying assembly 359, and the sealing plate is sealed. As the rotating shaft 358 rotates, the ring 3591 of the spraying assembly 359 also rotates, using centrifugal force to evenly spray the auxiliary materials onto the food through the spray holes 3592, so that the auxiliary materials and food are fully mixed. The separation tank 352 is securely installed inside the cavity 351 by the engagement of the hanging ear 354 with the slot 355 of the cavity 351, ensuring the stability of the mixing process.

[0074] The chopping device of this invention, by incorporating a stirring rod 367 bent at a preset angle, can more effectively stir food and increase the contact area between food and auxiliary materials. The spraying component 359 at the top of the rotating shaft 358 can evenly spray auxiliary materials during stirring, further improving mixing uniformity. The connection between the separating tank 352 and the cavity 351 via hooks 354 and slots 355 facilitates installation and disassembly, as well as cleaning and maintenance. The adjusting component 22 of the conveying trough 2 can flexibly adjust the angle of the trough 21, improving cutting accuracy and efficiency. In summary, this device effectively solves problems such as uneven addition of auxiliary materials and inconsistent product flavor in existing chopping processes, improving the quality and efficiency of food processing.
