Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a puffed corn flour mixing and adding device for baking products. Background Technology

[0002] Corn flour is rich in dietary fiber, vitamins, minerals, and functional elements, possessing abundant nutritional value and functional properties. However, due to the lack of gluten in corn, it does not easily form a network structure, resulting in a rough texture, poor palatability, and lower quality when consumed, significantly limiting its use in staple food processing. While extrusion puffing technology can effectively improve the quality characteristics of corn flour, current equipment cannot disperse or remove clumps of corn flour after moisture adjustment or the addition of other ingredients during baking production. Furthermore, the mixing shaft cannot be easily removed after use, leading to problems such as uneven mixing, inability to remove impurities, and difficulty in disassembly. Therefore, a mixing and adding device is urgently needed to solve these problems. Utility Model Content

[0003] The present invention aims to provide a puffed corn flour mixing and adding device for baking products, so as to solve the problems of uneven mixing, inability to remove impurities and inconvenience of disassembly of existing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The basic technical solution provided by this utility model is: a puffed corn flour mixing and adding device for baking products, including a mixing chamber and a feeding chamber. A mixing component is installed inside the mixing chamber. The mixing component includes a fixed frame and a stirring shaft. The top end of the stirring shaft is installed inside the fixed frame, and both ends of the fixed frame are locked in slots. The slots are opened on the mixing chamber. The bottom end of the stirring shaft is sleeved on a hexagonal column on a pulley. The stirring shaft is driven by a drive motor through a pulley and a belt. The drive motor is located on the side of the mixing chamber. Multiple sets of guide plates are installed inside the mixing chamber. A feeding chamber is installed on the top surface of the mixing chamber. A dispersing component and a sieving component are respectively installed in the feeding chamber. The dispersing component includes a fixed guide plate and a spiral shaft. The fixed guide plate is located above the spiral shaft. Two sets of spiral shafts are arranged opposite each other and are driven by gears at their ends. One set of spiral shafts is connected to the shaft of a second motor. The sieving component includes a mounting plate and a sieve plate. The sieve plate is slidably installed inside the mounting plate. One side of the sieve plate contacts a spring plate, and the other side contacts the side of a cam. The cam is connected to the shaft of a first motor, which is installed on the mounting plate.

[0006] Preferably, the feeding bin is provided with two sets of rotatable feeding guides, which are located below the screen plate. Both sets of feeding guides are provided with worm gears on their fixed shafts. The worm gears cooperate with the worms, which pass through the feeding bin.

[0007] Preferably, a fixed magnetic block is provided on the side of the feeding guide plate. The fixed magnetic block and the sliding magnetic block have opposite magnetic properties and are positioned correspondingly. The sliding magnetic block is slidably disposed in the chute. The chute is opened on the feeding bin, and the feeding bin is provided with scale lines.

[0008] Preferably, the mixing chamber is provided with an observation window, a transparent plate is provided at the observation window, and a light strip is provided on the bottom surface of the fixing frame.

[0009] The principle and beneficial effects of the basic technical solution are as follows: The added puffed corn flour is moved between two sets of spiral shafts by a fixed guide plate. A second motor drives the two sets of spiral shafts to rotate in opposite directions, compressing the clumps of corn flour and dispersing them for easier subsequent mixing. A first motor drives a cam to rotate, and the cam's protruding edge compresses and pushes the sieve plate, causing the spring plate to deform. When the cam's protruding edge stops compressing the sieve plate, the spring plate rebounds, causing the sieve plate to reset. This causes the sieve plate to vibrate reciprocally within the mounting plate, performing a secondary sieving of the corn flour and removing impurities. The finely separated corn flour falls into the mixing chamber, where a drive motor drives a stirring shaft to agitate it. Multiple guide plates further divert and agitate the corn flour, preventing clumping and effectively improving the uniformity of the mixture. After use, the feeding chamber is removed, releasing the pressure on the fixing frame. The fixing frame is then removed from the slot, allowing the stirring shaft to be taken out. This replaces the traditional fixed connection method, making the stirring shaft easy to remove and clean. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0017] like Figures 1-5 As shown: A puffed corn flour mixing and adding device for baking products includes a mixing chamber 1 and a feeding chamber 2. A mixing component is installed inside the mixing chamber 1. The mixing component includes a fixing frame 15 and a stirring shaft 17. The top end of the stirring shaft 17 is inserted into the fixing frame 15, and both ends of the fixing frame 15 are engaged in slots 6. The slots 6 are formed on the mixing chamber 1, and the fixing frame 15 is clamped in the slots 6. The feeding chamber 2 then presses and fixes the fixing frame 15, thereby fixing the stirring shaft 17 inside the mixing chamber 1. Removing the feeding chamber 2 allows the fixing frame 15 to be removed, making it easy to take out the stirring shaft 17 for cleaning. The bottom end of the stirring shaft 17 is sleeved on a hexagonal column on a pulley. The stirring shaft 17 is driven by a drive motor 4 through the pulley and belt. The drive motor 4 is located on the side of the mixing chamber 1, and the stirring shaft 17 is directly sleeved on the outside of the hexagonal column on the pulley, so that the drive motor 4 can drive the stirring shaft 17 to rotate through the pulley for mixing. The connection structure is simple and easy to disassemble. The mixing chamber 1 is equipped with multiple sets of guide plates 25. The agglomerated corn flour is diverted by the staggered sets of inclined guide plates 25, so that it can be better mixed. The top surface of the mixing chamber 1 is equipped with a feeding chamber 2. The feeding chamber 2 is equipped with a dispersing component and a screening component. The dispersing component includes a fixed guide plate 13 and a spiral shaft 14. The fixed guide plate 13 is located above the spiral shaft 14. Two sets of spiral shafts 14 are arranged opposite to each other and are driven by gears at their ends. The threads of the two sets of spiral shafts 14 are opposite and cooperate with each other. One set of spiral shafts 14 is connected to the shaft of motor 12. The threads of the two sets of spiral shafts 14 can disperse the agglomerated corn flour, so that the subsequent mixing effect is better. The screening component includes a mounting plate 7 and a sieve plate 10. The sieve plate 10 is slidably installed in the mounting plate 7. One side of the sieve plate 10 contacts the spring plate 11, and the other side contacts the side of the cam 8. The cam 8 is connected to the shaft of motor 9. Motor 9 is installed on the mounting plate 7. The vibration of the sieve plate 10 can sieve the corn flour that falls on the sieve plate 10. The finely separated corn flour passes through the sieve plate 10 and falls into the mixing chamber 1. Impurities are blocked on the sieve plate 10 to avoid affecting the mixing effect.

[0018] The specific implementation process is as follows:

[0019] In use, corn flour is added to the opening at the top of the feeding hopper 2. Guided by the fixed guide plate 13, the corn flour falls between the two sets of spiral shafts 14 through the gap in the middle of the guide plate 13. The second motor 12 and the first motor 9 are started. The second motor 12 drives one set of spiral shafts 14 to rotate. The two sets of spiral shafts 14 are connected by gears, causing them to rotate in opposite directions. The screw threads disperse any clumps of corn flour. The dispersed corn flour falls onto the sieve plate 10 through the gap between the threads on the two sets of spiral shafts 14. The first motor 9 drives the cam 8 to rotate, causing it to circulate and press against the sieve plate 10. The spring plate 11 keeps the sieve plate 10 pressed against the cam 8, causing the sieve plate 10 to reciprocate within the mounting plate 7, sieving the corn flour. The apertures on the sieve plate 10 are only wide enough for corn flour to pass through, separating impurities from the corn flour and preventing impurities from contaminating the product. The corn flour passing through the sieve plate 10 falls into the mixing chamber 1. The drive motor 4 is started, and through the transmission of the belt and pulley, the stirring shaft 17 rotates within the mixing chamber 1, mixing the corn flour. Simultaneously, as the stirring shaft 17 rotates, it pushes the corn flour against the wall of the mixing chamber 1. Multiple sets of staggered and inclined guide plates 25 guide the corn flour, pushing it back towards the stirring shaft 17, thus improving the mixing uniformity and allowing for better mixing. After use, the feeding chamber 2 is removed, freeing it from pressing against the fixing frame 15. The fixing frame 15 is then removed from the slot 6, releasing the fixation on the top of the stirring shaft 17. The stirring shaft 17 is then lifted to separate from the hexagonal column on the pulley, allowing it to be removed. The simple structure allows for quick disassembly, facilitating operation and easy maintenance and cleaning.

[0020] In this embodiment, two sets of rotatable feeding guides 20 are arranged opposite each other in the feeding bin 2. The feeding guides 20 are located below the sieve plate 10. Each set of feeding guides 20 has a worm wheel 24 on its fixed shaft. The worm wheel 24 cooperates with a worm 21, which passes through the feeding bin 2. Rotating the worm 21 causes it to drive the worm wheel 24 to rotate. The threads at both ends of the worm 21 are in opposite directions, so the two sets of worm wheels 24 rotate in opposite directions, driving the feeding guides 20 to rotate. This changes the opening and closing degree of the two sets of feeding guides 20, controlling the rate of corn flour addition, thus facilitating the operator to control the addition ratio.

[0021] In this embodiment, a fixed magnetic block 22 is provided on the side of the feeding guide plate 20. The fixed magnetic block 22 and the sliding magnetic block 23 have opposite magnetic properties and are positioned correspondingly. The sliding magnetic block 23 is slidably disposed in the slide groove 19, which is opened on the feeding bin 2. The feeding bin 2 is provided with scale lines 18. When the feeding guide plate 20 rotates, it drives the fixed magnetic block 22 to move. The fixed magnetic block 22 and the sliding magnetic block 23 are attracted by opposite magnetic properties, so that the sliding magnetic block 23 follows the fixed magnetic block 22 and moves in the slide groove 19. By observing the scale line 18 corresponding to the sliding magnetic block 23, the opening and closing degree of the feeding guide plate 20 can be clearly understood, which is convenient for the staff to adjust.

[0022] In this embodiment, an observation window 3 is provided on the mixing chamber 1, and a transparent plate 5 is provided at the observation window 3. A light strip 16 is provided on the bottom surface of the fixing frame 15. The light strip 16 provides illumination to the mixing chamber 1, and the staff can clearly observe the situation inside the mixing chamber 1 through the observation window 3 and the transparent plate 5.
