Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a low-sugar biscuit raw material mixing and fermentation device. Background Technology

[0002] With the popularization of healthy eating concepts, the demand for low-sugar biscuits continues to grow in the snack food market due to their low calorie and low sugar content. In the production of low-sugar biscuits, the uniformity of raw material mixing and the stability of the fermentation environment are the core processes that determine the quality of the product. During the mixing stage, raw materials such as flour, sugar substitute, yeast, oil, and dietary fiber need to be fully integrated. During the fermentation stage, the temperature needs to be precisely controlled to ensure yeast activity and ensure that the dough has the appropriate fluffiness and flavor after fermentation. After the fermentation is completed and the finished product is taken out, the container needs to be thoroughly cleaned before new raw materials can be put in.

[0003] An existing patent (publication number: CN221749500U) discloses a wafer biscuit raw material mixing and fermentation device, including a tank body, a tank cover at the top of the tank body, a motor at the top of the tank cover, a stirring shaft below the motor, stirring rods on both sides of the stirring shaft, a telescopic rod at the bottom of the tank body, a tray at the top of the telescopic rod, a scraper at the top of the tray, rotating shafts on both sides of the tank body, support legs on the outer sides of both sets of rotating shafts, a base at the bottom of the support legs, and an adjustment component at the connection between the rotating shaft and the support leg.

[0004] The aforementioned patent, during use, incorporates a tray and scraper. After the raw materials are mixed, the tank is rotated 180° using an adjusting component. During this process, the raw materials inside the tank flow downwards. Since the tray and scraper are positioned above, they slide downwards under their own weight and scrape away any remaining raw materials on the inner wall of the tank, effectively improving the cleaning efficiency of the tank and reducing the labor intensity of workers. However, because the raw materials are rich in flour and oil, residues will adhere to the inner wall of the tank, and cleaning the inner wall of the tank using only the tray and scraper is not thorough. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a low-sugar biscuit ingredient mixing and fermentation device, which has the advantage of more thorough cleaning of the inner wall of the tank, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-sugar biscuit raw material mixing and fermentation device, comprising a stirring component for stirring and fermentation and a cleaning component for cleaning. The stirring component includes a tank and a top cover. A rotating shaft sleeve is inserted into the upper surface of the top cover. A rotating shaft is fixed to the upper surface of the rotating shaft sleeve. The rotating shaft passes through the rotating shaft sleeve. Two mounting rings are fixed to the outer surface of the rotating shaft. Multiple mounting frames arranged in a circular pattern are fixed to the outer surfaces of the two mounting rings. A stirring frame is inserted between two corresponding mounting frames. The stirring frame is fixed to the mounting frame by bolts. A rubber strip is installed on the side of the stirring frame. The rubber strip is in contact with the inner wall of the tank.

[0007] The cleaning assembly includes multiple fixed frames fixed to the bottom surface of the rotating shaft sleeve. A swing arm is hinged to the end of each fixed frame. Multiple nozzles are installed on the bottom surface of the swing arm. A groove is formed on the upper surface of the rotating shaft. A connecting pipe is installed inside the groove of the rotating shaft. The bottom end of the connecting pipe passes through the rotating shaft and is connected to the nozzles through a pipe.

[0008] Furthermore, the tank body has an internal chamber, and a heating pipe is installed inside the tank body. The heating pipe is in contact with the tank body and is connected to an external heating device.

[0009] Through the above scheme, the heating pipe can uniformly heat the raw materials in the tank to maintain the appropriate temperature environment required for fermentation, avoid local temperature being too high or too low, which would affect yeast activity, and ensure the stability and consistency of the fermentation process of low-sugar biscuit raw materials.

[0010] Furthermore, a limiting block is fixed at the hinge position between the fixed frame and the swing arm, a slot is provided at the other end of the fixed frame, a corresponding locking block is fixed on the side of the swing arm, and a limiting plate is hinged to the inner wall of the fixed frame.

[0011] With the above scheme, when the stirring and fermentation operation is carried out, the swing arm retracts into the fixed frame and is engaged with the fixed frame by the locking block. When the cleaning operation is carried out, the locking block is pressed to make the swing arm fall. The limiting block restricts the falling angle of the swing arm, so that the nozzle on the swing arm is angled downwards and aligned with the inner wall of the tank. The limiting plate falls due to its own weight and locks the inner wall of the swing arm, preventing the swing arm from rotating due to the recoil force of the nozzle during operation.

[0012] Furthermore, a base is provided below the tank body, a fixing frame is fixed on the upper surface of the base, a chuck and a support shaft are fixed on the side of the tank body, a plug rod is inserted into the side of the fixing frame, and the other end of the plug rod is inserted into the chuck.

[0013] The above scheme uses the insertion of the rod and the chuck to limit the rotation of the tank, making it easier to maintain the stability of the tank during material feeding or cleaning.

[0014] Furthermore, a vertical plate is fixed to the upper surface of the base, a top plate is provided on the side of the vertical plate, a track groove is opened on the side of the vertical plate, a track block is fixed to the side of the top plate, the track block is slidably connected to the track groove, a drive motor is installed at the top of the vertical plate, a threaded rod is installed at the output end of the drive motor, and the threaded rod passes through the track block and is threadedly connected to the track block.

[0015] The above scheme drives the drive motor to rotate the threaded rod, causing the track block to slide up and down along the track groove, thereby driving the top plate to rise and fall synchronously.

[0016] Furthermore, the top plate has a cavity inside, the top end of the rotating shaft is located in the cavity, a gear ring is fixed on the outer surface of the rotating shaft, a gear is rotatably connected to the inner wall of the top plate cavity, the gear meshes with the gear ring, a stirring motor is installed on the inner wall of the top plate cavity, and the output end of the stirring motor is connected to the gear.

[0017] With the above scheme, when the stirring motor is running, it drives the gear to rotate. The gear meshes with the gear ring, thereby driving the rotating shaft to rotate. The rotating shaft drives the stirring frame to rotate inside the tank through the mounting ring and mounting frame.

[0018] Furthermore, a pump is installed in the cavity inside the top plate, and the output end of the pump is inserted into a connecting pipe.

[0019] Through the above scheme, the pump can pressurize and deliver external cleaning fluid or clean water to the connecting pipe, and then distribute it to each nozzle through the pipeline, so that the nozzle can rinse the inner wall of the tank at a higher pressure. Combined with the residual material pre-scraped off by the rubber strip, it can achieve deep cleaning of the inner wall of the tank, effectively remove the attached flour and grease residue, and improve the cleaning effect of the tank.

[0020] Furthermore, a pressure relief valve is provided on the upper surface of the top cover, a positioning groove is provided on the upper surface of the top cover, and a positioning block is fixed on the upper surface of the tank body.

[0021] With the above solution, the positioning block and the positioning groove are adapted to each other. When the top cover is closed on the top of the tank, the positioning block is embedded in the positioning groove, which can quickly achieve accurate alignment between the top cover and the tank, and avoid collision between the stirring component or cleaning component and the inner wall of the tank due to installation deviation.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0023] This low-sugar biscuit ingredient mixing and fermentation device uses heating pipes to evenly heat the tank, maintaining a suitable fermentation temperature to ensure yeast activity. After fermentation, when the raw materials are removed and the tank is cleaned, the heating pipes heat the inner wall of the tank, causing any remaining dough to dry and clump together quickly, making it easy to scrape off the dough residue with tools. For any attached grease, the stirring motor drives the rubber strips on the side of the stirring frame to scrape the inner wall of the tank. The rubber strips adhere tightly to the inner wall, separating the flour residue and grease mixture. At the same time, the nozzles continuously spray high-pressure cleaning fluid to wash the inner wall, separating any remaining impurities and grease from the inner wall of the tank, thus completing the cleaning of the tank.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1 - Figure 8 This embodiment of a low-sugar biscuit raw material mixing and fermentation device includes a stirring component 1 for stirring and fermentation and a cleaning component 2 for cleaning. The stirring component 1 includes a tank body 101 and a top cover 102. A rotating shaft sleeve 103 is inserted into the upper surface of the top cover 102. A rotating shaft 104 is fixed to the upper surface of the rotating shaft sleeve 103. The rotating shaft 104 passes through the rotating shaft sleeve 103. Two mounting rings 105 are fixed to the outer surface of the rotating shaft 104. Multiple mounting frames 106 arranged in a circle are fixed to the outer surface of each of the two mounting rings 105. A stirring frame 107 is inserted between two corresponding mounting frames 106. The stirring frame 107 is fixed to the mounting frame 106 by bolts. A rubber strip 108 is installed on the side of the stirring frame 107. The rubber strip 108 is in contact with the inner wall of the tank body 101.

[0038] Please see Figure 4 , Figure 5 and Figure 6 The cleaning component 2 includes multiple fixed frames 201 fixed to the bottom surface of the rotating shaft sleeve 103. The ends of the fixed frames 201 are hinged to the swing arms 202. Multiple nozzles 203 are installed on the bottom surface of the swing arms 202. The upper surface of the rotating shaft 104 is provided with a groove. A connecting pipe 204 is installed inside the groove of the rotating shaft 104. The bottom end of the connecting pipe 204 passes through the rotating shaft 104 and is connected to the nozzles 203 through the pipe.

[0039] Please see Figure 5 , Figure 7 and Figure 8The tank 101 has an internal chamber, and a heating pipe 109 is installed inside the tank 101. The heating pipe 109 is in contact with the tank 101 and is connected to an external heating device. The heating pipe 109 can uniformly heat the raw materials in the tank 101 to maintain a suitable temperature environment for fermentation, avoid excessively high or low local temperatures affecting yeast activity, and ensure the stability and consistency of the fermentation process of the low-sugar biscuit raw materials. A limit block 205 is fixed at the hinge position between the fixed frame 201 and the swing arm 202. A slot is provided at the other end of the fixed frame 201. The side of the swing arm 202 is fixed. There is a corresponding locking block 206 for the slot. The inner wall of the fixed frame 201 is hinged with a limiting plate 207. When the stirring and fermentation operation is carried out, the swing arm 202 retracts into the fixed frame 201. The swing arm 202 is locked to the fixed frame 201 through the locking block 206. When the cleaning operation is carried out, the locking block 206 is pressed to make the swing arm 202 fall. The limiting block 205 restricts the falling angle of the swing arm 202, so that the nozzle 203 on the swing arm 202 is angled downward and aligned with the inner wall of the tank 101. The limiting plate 207 falls due to its own weight and locks the inner wall of the swing arm 202 to prevent the recoil of the nozzle 203 from causing the swing arm 202 to rotate.

[0040] Please see Figure 1 , Figure 2 and Figure 3 A base 3 is provided below the tank body 101. A fixing frame 4 is fixed on the upper surface of the base 3. A chuck 5 and a support shaft 6 are fixed on the side of the tank body 101. A plug rod 7 is inserted into the side of the fixing frame 4. The other end of the plug rod 7 is inserted into the chuck 5. The plug rod 7 and the chuck 5 limit the rotation of the tank body 101, so that the tank body 101 can maintain its stability when unloading or cleaning. A vertical plate 8 is fixed on the upper surface of the base 3. A top plate 9 is provided on the side of the vertical plate 8. A track groove is opened on the side of the vertical plate 8. A track block 10 is fixed on the side of the top plate 9. The track block 10 is slidably connected to the track groove. A drive motor 11 is installed at the top of the vertical plate 8. A threaded rod 12 is installed at the output end of the drive motor 11. The threaded rod 12 passes through the track block 10 and is threadedly connected to the track block 10. The drive motor 11 drives the threaded rod 12 to rotate, so that the track block 10 slides up and down along the track groove, thereby driving the top plate 9 to rise and fall synchronously.

[0041] Please see Figure 4 , Figure 5 and Figure 7The top plate 9 has an internal chamber, and the top end of the rotating shaft 104 is located in the chamber. A gear ring 13 is fixed to the outer surface of the rotating shaft 104. A gear 14 is rotatably connected to the inner wall of the chamber of the top plate 9, and the gear 14 meshes with the gear ring 13. A stirring motor 15 is installed on the inner wall of the chamber of the top plate 9. The output end of the stirring motor 15 is connected to the gear 14. When the stirring motor 15 is running, it drives the gear 14 to rotate. The gear 14 meshes with the gear ring 13, thereby driving the rotating shaft 104 to rotate. The rotating shaft 104 drives the stirring frame 107 to rotate inside the tank 101 through the mounting ring 105 and the mounting frame 106. A pump 16 is installed in the internal chamber of the top plate 9. The output end of the pump 16 is inserted into the connecting pipe 204. The pump 16 can pressurize and deliver external cleaning liquid or clean water to the connecting pipe 204. The liquid is then distributed through pipes to each nozzle 203, allowing the nozzles 203 to rinse the inner wall of the tank 101 at a higher pressure. Combined with the residual material pre-scraped off by the rubber strip 108, this achieves deep cleaning of the inner wall of the tank 101, effectively removing attached flour and grease residues and improving the cleaning effect of the tank 101. A pressure relief valve 17 is provided on the upper surface of the top cover 102, and a positioning groove 18 is provided on the upper surface of the top cover 102. A positioning block 19 is fixed on the upper surface of the tank 101. The positioning block 19 is adapted to the positioning groove 18. When the top cover 102 is closed on the top of the tank 101, the positioning block 19 is embedded in the positioning groove 18, which can quickly achieve precise alignment between the top cover 102 and the tank 101, avoiding collision between the stirring component 1 or the cleaning component 2 and the inner wall of the tank 101 due to installation deviation.

[0042] It should be noted that during the cleaning operation, the heating pipe 109 heats the inner wall of the tank 101, causing the remaining fabric to dry and clump together quickly. After using tools to scrape off the fabric residue, the residue is cleaned up, and then the top cover 102 is closed and the pump 16 is started to carry out the rinsing operation.

[0043] The working principle of the above embodiment is as follows: Flour, sugar substitute, yeast, oil, dietary fiber and other raw materials are put into the inside of the tank 101. The stirring motor 15 is started and drives the rotating shaft 104 to rotate through the meshing of the gear 14 and the gear ring 13 on the rotating shaft 104. The rotating shaft 104 drives the stirring frame 107 to rotate synchronously through the mounting ring 105 and the mounting frame 106. The rubber strip 108 on the side of the stirring frame 107 is tightly attached to the inner wall of the tank 101. During the stirring process, the raw materials such as flour, sugar substitute, yeast, oil and other raw materials are fully mixed, and the raw materials initially attached to the inner wall are scraped off at the same time, which reduces the burden of subsequent cleaning.

[0044] During the mixing process, the heating pipe 109 is connected to an external heating device, and heat is supplied evenly by contacting the inner wall of the tank 101, stabilizing the temperature inside the tank within a suitable range for yeast activity. The top cover 102 is sealed to the tank 101, and the pressure relief valve 17 balances the air pressure inside the tank in real time, providing a stable micro-pressure fermentation environment for the dough, ensuring that the dough has a fluffy texture and uniform flavor after fermentation.

[0045] After fermentation, the top plate 9 rises, causing the top cover 102 to separate from the tank 101. The insert rod 7 is pulled out to release the chuck 5, and the tank 101 is flipped over to remove the finished product. Then, the heating pipe 109 restarts, heating the inner wall of the tank 101 to quickly dry and clump the remaining flour. Large pieces of residue are manually removed with tools. The locking block 206 on the side of the swing arm 202 is pressed, releasing the swing arm 202 from the fixed frame 201. The limiting block 205 restricts the falling angle of the swing arm 202, and the limiting plate 207 falls and locks due to its own weight. Hold the swing arm 202 to prevent shaking during rinsing. After the top cover 102 is reset, the stirring motor 15 drives the stirring frame 107 to rotate at low speed. The rubber strip 108 scrapes the inner wall again to remove residual grease and fine flour. At the same time, the pump 16 starts and pressurizes the external cleaning liquid, which is then transported to each nozzle 203 through the connecting pipe 204 and branch pipes. The high-pressure water flow precisely rinses the inner wall, and the scraping of the rubber strip 108 forms a dual action of mechanical peeling and water impact, which thoroughly removes the attached grease and residual impurities.
