Description

Technical Field

[0001] This invention belongs to the field of oat flour processing technology, specifically a fermentation and turning device for processing fermented oat flour. Background Technology

[0002] Oat flour is a powdered product made from oat grains through processes such as cleaning, dehulling, and milling (or pulverizing). Based on processing precision and mesh size, it can be divided into coarse oat flour and fine oat flour. Oat flour fermentation is a process in which microorganisms (such as lactic acid bacteria and yeast) decompose and transform the components in oat flour. Its core purpose is to optimize the processing characteristics, nutritional quality, and eating experience of oat flour. Some nutrients in oats (such as phytic acid) can hinder the body's absorption of minerals (calcium, iron, zinc, etc.). During fermentation, phytase produced by microorganisms can decompose phytic acid, releasing the bound minerals and improving the utilization rate of nutrients. In addition, microorganisms can also break down the proteins in oat flour into small peptides and amino acids, increasing the content of free amino acids; therefore, fermentation is necessary.

[0003] Traditional equipment still has some drawbacks when fermenting oat flour: 1. Traditional screening methods are mostly single screening or static screening, which not only have low processing efficiency, but also easily cause the screening channel to be blocked due to the accumulation of impurities. At the same time, it is difficult to accurately separate impurities such as wheat bran and gravel. The residue of impurities will directly affect the quality of subsequent fermentation. Conventional sieve plates are mostly fixed installation structures, the disassembly and assembly process is cumbersome, and it is not possible to flexibly replace sieve plates with different mesh sizes, making it difficult to meet the processing needs of oat flour with different particle sizes. 2. Simply stirring or turning the oat flour can cause local accumulation of materials, making it difficult to break up clumps of oat flour and mix the bottom materials. This can lead to uneven distribution of fermentation bacteria, resulting in fermentation failure or unstable product quality. Directly adding oat flour can also impact the inner wall and components of the fermentation chamber, causing materials to splash and clump together, while also exacerbating wear and tear on components and causing jamming.

[0007] Preferably, two symmetrically arranged docking plates are fixedly installed on the side of the central cylinder away from the central cylinder. The docking plates have an insertion hole in the middle. Adjustment grooves are opened on both sides of the U-shaped frame. A snap-fit ​​bracket is slidably installed in the adjustment groove. A spring is connected between the snap-fit ​​bracket and the inside of the adjustment groove. The upper part of the snap-fit ​​bracket is L-shaped, and the snap-fit ​​bracket is inserted into the insertion hole in the docking plate under the abutment of the spring.

[0008] Preferably, a set of two sieve plates is provided with symmetrically arranged slope blocks fixed to the central cylinder, and a drop opening is provided between the two slope blocks on the central cylinder. The drop opening is sealed by a hinged plate, and a receiving groove is provided on one side of the hinged plate on the inner wall of the central cylinder for storing the hinged plate.

[0009] Preferably, the recovery section includes a movable rod rotatably mounted in the inner cavity of the central cylinder. A track groove is provided on one side of the movable rod. A connecting column corresponding to multiple opening and closing plates is slidably mounted on the track groove. A docking block is fixedly mounted on one end of the connecting column.

[0010] Preferably, a plurality of rod-shaped grooves are provided on one side of the central cylinder, and an internal rod is slidably installed in the rod-shaped groove. A spring located in the rod-shaped groove is sleeved on the outside of the internal rod, and an abutment plate for sealing one side of the central cylinder is installed at one end of the plurality of internal rods.

[0011] Preferably, a push rod is slidably mounted on one side of the central cylinder, a spring is sleeved on the outside of the central cylinder, and a cleaning plate located inside the central cylinder is fixedly mounted on one end of the push rod.

[0012] Preferably, the pushing part includes a reciprocating rod that passes through and slides on the inner wall of the fermentation box. A roller frame is provided on one side of the reciprocating rod, and a fixing member fixed to the fermentation box is provided on one side of the roller frame. A cylinder is rotatably mounted on the fixing member, and a cam is fixedly mounted on one side of the cylinder. The cam is always in contact with the roller frame.

[0013] Preferably, the linkage assembly includes a driven bevel gear fixedly mounted on the cylinder extension end, and a driving bevel gear fixed to the central rod meshing on one side of the driven bevel gear.

[0014] Preferably, the spray unit includes a spray box, with a delivery pipe on one side of the spray box for supplying fermentation liquid to the spray box, and multiple sets of symmetrically arranged spray nozzles on the central rod.

[0015] The beneficial effects of this invention are: 1. This invention features a central cylinder equipped with multiple symmetrical sieves. The central rod drives the central cylinder to rotate synchronously via a pulley system, enabling continuous feeding and sieving of oat flour. This significantly improves pre-treatment efficiency before fermentation. The sieves precisely separate bran, grit, and substandard particles from the oat flour, preventing impurities from affecting fermentation quality. Symmetrical slope blocks are provided between each set of sieves to guide the intercepted impurities. When the opening plate opens the drop outlet, impurities can smoothly slide down the slope into the central cylinder for temporary storage, preventing impurities from accumulating and clogging the sieving channel. The U-shaped frame and the connecting plate are quickly connected and fixed via a spring-driven snap-fit ​​frame. The sieves can be disassembled and assembled by manually adjusting the snap-fit ​​frame, facilitating cleaning or replacement of sieves with different mesh sizes, and adapting to oat flour processing scenarios with different particle size requirements.

[0016] 2. This invention uses a central rod to drive the rotation of a turning frame, repeatedly lifting oat flour. Combined with the horizontal movement of a swing plate driven by a horizontal frame, this creates a combined motion of "rotational turning + horizontal stirring." The filter holes on the swing plate simultaneously sieve the material, breaking up clumps of oat flour and preventing material accumulation at the bottom, ensuring uniform fermentation and preventing fermentation failure. Through the bevel gear engagement / disengagement control of the linkage group, the "rotation + horizontal combined stirring" and "single rotation stirring" modes can be flexibly switched. Strong stirring in the early stages of fermentation breaks up the material, while weak stirring in the later stages protects the activity of the fermentation bacteria, adapting to the process requirements of different fermentation stages and improving product quality stability.

[0017] 3. This invention precisely connects the internal frame's receiving interface with the fermentation chamber's inlet, guiding the falling oat flour and preventing it from directly impacting the fermentation chamber's inner wall and the turning components. This reduces the probability of material splashing and clumping, while also lowering the risk of wear and jamming on components such as the turning frame and swing plate. The recovery section inside the central cylinder can temporarily store sieved impurities. Manually pushing the push rod will cause the cleaning plate to scrape the inner wall of the central cylinder, pushing the impurities to the discharge area. While pushing the impurities, the cleaning plate can also scrape and clean the inner wall of the central cylinder, preventing impurities from adhering and accumulating. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-13As shown, this invention is a fermentation device for processing fermented oat flour, including a fermentation box 1. A central rod 12 is rotatably mounted in the middle of the fermentation box 1. One end of the central rod 12 is connected to a motor 15 installed on the side of the fermentation box 1. A turning frame 13 is fixedly mounted on the central rod 12. A T-slot 131 is formed on the turning frame 13. A guide rod 133 fixed to the turning frame 13 is fixedly mounted on the upper part of the T-slot 131. Multiple equidistantly arranged and slidably nested swing plates 132 are slidably mounted in the T-slot 131 outside the guide rod 133. A spring sleeved outside the guide rod 133 connects two adjacent swing plates 132. A horizontal frame 14 is also provided on the central rod 12, which slides along the axis of the central rod 12. Multiple sets of irregularly shaped plates 141 are fixedly installed on the upper part of the fermentation box 1, located in the middle of two adjacent swing plates 132. The fermentation box 1 is provided with a pushing part on the side away from the motor 15, which moves the horizontal frame 14 along the axis of the central rod 12. The pushing part is linked with the central rod 12 through a linkage group. A spray group is also provided on the outside of the fermentation box 1. A processing box 2 is fixedly installed on the upper part of the fermentation box 1. A central cylinder 21 is installed in the center of the processing box 2 by a motor. Multiple sets of two U-shaped frames 211 are provided on the central cylinder 21. A sieve plate 212 is detachably installed in the middle of the U-shaped frame 211. The central cylinder 21 and the central rod 12 are driven by a belt pulley group. A recycling part is embedded in the central cylinder 21. A movable abutment plate 26 is provided on one side of the central cylinder 21.

[0023] When the central rod 12 rotates, it can drive the turning frame 13 and the horizontal frame 14 to rotate and turn the oat flour in the fermentation box 1 during fermentation, so that the oat flour can be repeatedly lifted during fermentation, avoiding the accumulation of oat flour at the bottom during fermentation, which would cause uneven fermentation or fermentation failure. When the motor 15 is turned on and drives the central rod 12 to rotate, the central rod 12 drives the turning frame 13 and the horizontal frame 14 to rotate. At this time, the horizontal frame 14 is pushed by the pushing part, and the horizontal frame 14 as a whole drives multiple irregular plates 141 to move horizontally along the axis of the central rod 12. When the irregular plates 141 move, they squeeze the swing plate 132, so that the swing plate 132 slides on the guide rod 133. At this time, the multiple swing plates 132 move horizontally along the axis of the central rod 12, realizing the horizontal turning of the oat flour in the fermentation box 1 during fermentation. The swing plate 132 is provided with multiple filter holes. While the oat flour is being stirred by the swing plate 132, the filter holes can repeatedly sift the oat flour, enhancing its looseness. It should be noted that the horizontal movement of the multiple swing plates 132, together with the turning frame 13 and the horizontal frame 14, can rotate and stir the oat flour in the fermentation box 1. At the same time, the multiple swing plates 132 can also stir the oat flour horizontally during the fermentation process, spreading and dispersing the oat flour. By increasing the stirring path of the oat flour, a highly efficient stirring effect is achieved. It should be noted that during the fermentation of oat flour, the intensity of stirring can be reduced after the oat flour has fermented to a certain extent. Therefore, the present invention, through the setting of the linkage group, can cause multiple swing plates 132 to cancel the stirring and spreading of the oat flour. Specifically, the cylinder 161 is activated to retract, and when the cylinder 161 retracts, it drives the driven bevel gear 163 to move, thereby causing the driven bevel gear 163 to disengage from the driving bevel gear 162. At this time, the center rod 12 rotates, driving the flipping frame 13 and the horizontal frame. When the oat flour in the fermentation box 1 is stirred, the linkage group cancels the drive of the pushing part, so that the multiple irregular plates 141 cancel the horizontal compression of the multiple swing plates 132; the setting of the spray group enables the addition of fermentation liquid to the oat flour during fermentation in the fermentation box 1. Specifically, the external supplement liquid is pumped into the spray box 17 through the conveying pipe 171, and then the spray box 17 sprays the fermentation liquid into the oat flour through the multiple spray nozzles 172 opened on the central rod 12; When motor 15 is turned on, it drives the central rod 12 to rotate, stirring the oat flour in fermentation chamber 1. Simultaneously, the pulley system also drives the central cylinder 21 in processing chamber 2 to rotate. Before fermentation, the oat flour contains a small amount of bran and grit. If not treated, these impurities will affect the fermentation quality. Specifically, before fermentation, the top plate of processing chamber 2 is opened. Oat flour is then placed through the inlet at the top of processing chamber 2 between two sieves 212. As the central cylinder 21 rotates, the required amount of oat flour falls through the sieve holes between the two sieves 212. At this time, the arc-shaped plate at the bottom of processing chamber 2 is opened. The oat flour sifted from the sieve plate 212 can fall into the processing box 2. However, wheat bran, grit, and oat flour that do not meet the particle number requirements cannot be sifted through the sieve plate 212. Before rotating towards the arc plate at the opening formed between the two sieve plates 212, the corresponding opening and closing plate 214 is moved away. This allows oat flour, wheat bran, and grit that do not meet the particle number requirements to fall into the central cylinder 21 through the drop opening between the two slope blocks 213 for temporary storage. Since the lower part of the slope of the two slope blocks 213 is connected to one side of the drop opening, oat flour, wheat bran, and grit that do not meet the particle number requirements can smoothly fall into the central cylinder 21 through the opening and closing plate 214 between the two sieve plates 212 along the slope of the slope block 213. With multiple sets of U-shaped frames 211, oat flour can be continuously added to the placement space formed between the sieve plates 212 on each set of U-shaped frames 211 when the central cylinder 21 rotates, thereby improving the processing efficiency of oat flour before fermentation. The combined horizontal sliding and rotating motion of the swing plate 132, along with the sieving effect of the filter holes, can break up clumps of oat flour and ensure full contact between the fermentation liquid and the oat flour. This prevents the concentration of the fermentation liquid from being too high or too low in some areas, ensuring the consistency of the fermentation environment and improving the quality stability of the final fermented product. The repeated lifting and spreading of the oat flour increases its contact area with the air in the fermentation chamber 1, providing sufficient oxygen for the aerobic fermentation bacteria, promoting the metabolic activity of the bacteria, and shortening the fermentation cycle. At the same time, the "spreading" effect of the horizontal stirring can avoid the problem of anaerobic spoilage caused by local material compaction. The central rod 12 synchronously drives the central cylinder 21 of the processing box 2 through the pulley set, realizing the linkage operation of oat flour screening and impurity removal and fermentation turning. There is no need to set up an additional screening drive device, reducing equipment energy consumption and floor space, realizing the integrated operation of "pre-treatment-fermentation", improving the automation level and processing efficiency of the production line. After screening by the sieve plate 212 in the processing box 2, wheat bran, gravel and unqualified particles slide down into the central cylinder 21 through the slope block 213 for temporary storage, avoiding impurities from mixing into the fermentation material and affecting the quality. The recovered unqualified materials can be collected and then crushed and screened again to improve the raw material utilization rate and reduce production costs.

[0024] By using a linkage cylinder with bevel gears to engage or disengage, the system can flexibly switch between "rotation + horizontal compound stirring" and "single rotation stirring" modes according to the different needs of oat flour fermentation stages, such as strong stirring to disperse materials in the early stage and weak stirring to prevent damage to bacteria in the later stage. This adapts to different fermentation process parameters and enhances the equipment's adaptability to different batches and qualities of oat raw materials. The spray unit precisely replenishes the fermentation liquid through the spray nozzle 172 of the central rod 12. Combined with the turning action of the material, the fermentation liquid can be evenly distributed. At the same time, the closed structure of the fermentation box 1, together with the turning action of the material, can more stably maintain the key fermentation parameters such as temperature and humidity inside the box, and reduce external environmental interference. The sieve plate 212 adopts a detachable installation method, which is convenient for later cleaning and replacement of sieve plates 212 with different apertures to adapt to oat flour processing with different particle size requirements. The sliding nested structure of the swing plate 132 and the guide rod 133 does not require disassembling the entire turning frame 13 during disassembly and cleaning, reducing maintenance difficulty and downtime. The fermentation box 1 has a feed inlet 101 on its upper end face and a discharge port 102 corresponding to the feed inlet 101 on its lower end face. An internal frame 11 is slidably installed on the inner wall of the fermentation box 1. The upper part of the internal frame 11 has a receiving interface 112 and the lower part of the internal frame 11 has a through opening 113. The side wall of the internal frame 11 has an arc-shaped adjustment groove 103. A handle 111 fixed to the internal frame 11 is slidably installed in the adjustment groove 103.

[0025] When the oat flour falling from the processing box 2 into the fermentation box 1 is collected in the fermentation box 1 for fermentation, the handle 111 is manually pushed down to move within the adjusting groove 103. As the handle 111 moves, it causes the internal frame 11 to rotate counterclockwise along the axis of the fermentation box 1. When the receiving interface 112 on the internal frame 11 aligns with the feed inlet 101 on the fermentation box 1, the oat flour falling from the processing box 2 can enter the fermentation box 1. (See reference...) Figure 11 As shown, after the oat flour fermentation process is completed, when the oat flour in the processing box 2 is discharged from the fermentation box 1, the handle 111 is manually moved upward to slide down in the adjustment groove 103. When the handle 111 slides, it drives the internal frame 11 to rotate clockwise inside the fermentation box 1. When the through-hole 113 on the internal frame 11 rotates to coincide with the discharge port 102, the fermented oat flour in the processing box 2 can then fall. The internal frame 11 precisely connects to the feed inlet 101 via the receiving interface 112, enabling it to directionally receive and guide the oat flour falling from the processing box 2. This prevents the oat flour from directly impacting the inner wall of the fermentation box 1 or the turning components during the feeding process, reducing the probability of material splashing and clumping. It also prevents wear or jamming of components such as the turning frame 13 and the swing plate 132 due to material impact. During the oat flour fermentation stage, the internal frame 11 can be rotated to misalign the receiving interface 112 with the feed inlet 101 and the through-hole 113 with the discharge port 102, creating a relatively enclosed space inside the fermentation box 1. This enclosed space reduces the loss of temperature and humidity inside the fermentation box 1, prevents external impurities and bacteria from entering, stabilizes the fermentation environment, and ensures the activity and fermentation effect of the fermentation flora. During discharge, the internal frame 11 is rotated to align the through-hole 113 with the discharge port 102. Combined with the rotation and stirring of the flipping frame 13, the fermented oat flour can slide down the through-hole 113 in a directional manner, preventing material residue at the bottom of the fermentation box 1. At the same time, the overlapping area of ​​the through-hole 113 and the discharge port 102 can be adjusted by controlling the rotation angle of the internal frame 11, so as to achieve flexible adjustment of the discharge speed. During feeding, the receiving port 112 can guide the oat flour to the designated area in the fermentation box 1. With the subsequent rotation and horizontal stirring of the turning frame 13, the material can be spread evenly more quickly. Compared with direct feeding without guidance, this design can reduce the initial problem of local material accumulation and shorten the time cost of early stirring. Two symmetrically arranged docking plates 2120 are fixedly installed on the side of the central cylinder 21 away from the central cylinder 21. The docking plates 2120 have an insertion hole in the middle. The U-shaped frame 211 has an adjustment groove 2110 on both sides. A snap-fit ​​bracket 2111 is slidably installed in the adjustment groove 2110. The snap-fit ​​bracket 2111 and the adjustment groove 2110 are connected by a spring. The upper part of the snap-fit ​​bracket 2111 is L-shaped, and the snap-fit ​​bracket 2111 is inserted into the insertion hole in the docking plate 2120 under the abutment of the spring.

[0026] When disassembling and assembling the sieve plate 212 on the U-shaped frame 211 to replace the sieve plate 212 with a different mesh size, manually move the snap-fit ​​bracket 2111 in the adjusting groove 2110 so that it moves away from the sieve plate 212 when the spring is squeezed and moves out of the docking plate 2120. Then, pull the sieve plate 212 upward from the U-shaped frame 211 and replace it with a sieve plate 212 with a different mesh size. Then, remove the restriction on the snap-fit ​​bracket 2111 so that it resets under the action of the spring, so that the docking plate 2120 on the side of the sieve plate 212 placed in the middle of the U-shaped frame 211 can be inserted. A set of two sieve plates 212 are provided with symmetrically arranged slope blocks 213 fixed to the central cylinder 21. A drop opening is provided between the two slope blocks 213 on the central cylinder 21. The drop opening is blocked by a hinged plate 214. A receiving groove 215 is provided on one side of the hinged plate 214, which is opened on the inner wall of the central cylinder 21 and is used to store the hinged plate 214.

[0027] By setting two slope blocks 213, the bran, gravel and clumps of oat flour that are blocked by the two sieve plates 212 can be guided so that when the opening and closing plate 214 moves to open the drop outlet, the bran, gravel and clumps of oat flour located between the two sieve plates 212 can enter the central cylinder 21 for temporary storage. The recovery unit includes a central cylinder 21 with a movable rod 22 rotatably mounted inside. A track groove 23 is provided on one side of the movable rod 22. A connecting post 231 corresponding to multiple opening and closing plates 214 is slidably mounted on the track groove 23. A docking block 232 is fixedly mounted on one end of the connecting post 231. A slot is provided on the docking block 232. An insert plate 243 is installed at the lower end of the opening and closing plate 214 via an electric push rod.

[0028] Multiple rod-shaped grooves 252 are provided on one side of the central cylinder 21. An internal rod 253 is slidably installed in the rod-shaped groove 252. A spring located in the rod-shaped groove 252 is sleeved on the outside of the internal rod 253. An abutment plate 26 for sealing one side of the central cylinder 21 is installed at one end of the multiple internal rods 253.

[0029] A push rod 25 is slidably mounted on one side of the central cylinder 21. A spring is sleeved on the outside of the central cylinder 21. A cleaning plate 251 located inside the central cylinder 21 is fixedly mounted on one end of the push rod 25.

[0030] When discharging the bran, gravel, and clumps of oat flour collected in the central cylinder 21, the push rod 25 is manually pushed. When the push rod 25 is pushed, it causes the cleaning plate 251 to scrape inside the central cylinder 21, thereby pushing the bran, gravel, and clumps of oat flour collected inside the central cylinder 21. When the cleaning plate 251 moves to the side of the central cylinder 21 and squeezes the abutment plate 26, the abutment plate 26 moves away from the central cylinder 21 after being squeezed. When the central cylinder 21 moves, the built-in rod 253 in the rod groove 252 squeezes the spring and moves outward. At this time, a discharge area is formed between the abutment plate 26 and the side of the central cylinder 21, and the bran, gravel, and clumps of oat flour inside the central cylinder 21 can be discharged. When the abutment plate 26 is in contact with the outside, under the elastic force of the spring, the rod groove 252 drives the abutment plate 26 to stick to the side of the central cylinder 21, thereby completing the sealing inside the central cylinder 21 again.

[0031] The pushing part includes a reciprocating rod 165 that passes through and slides on the inner wall of the fermentation box 1. A roller frame 166 is provided on one side of the reciprocating rod 165. A fixing member 16 that is fixed to the fermentation box 1 is provided on one side of the roller frame 166. A cylinder 161 is rotatably mounted on the fixing member 16. A cam 164 is fixedly mounted on one side of the cylinder 161. The cam 164 is always in contact with the roller frame 166.

[0032] The linkage assembly includes a driven bevel gear 163 fixedly mounted on the telescopic end of the cylinder 161, and a driving bevel gear 162 fixed to the center rod 12 meshing on one side of the driven bevel gear 163.

[0033] When cylinder 161 is opened and pushed forward, it drives driven bevel gear 163 to mesh with driving bevel gear 162. When the center rod 12 rotates, the driving bevel gear 162 rotates synchronously. When the driving bevel gear 162 rotates, it meshes with driven bevel gear 163, thereby driving cylinder 161 to rotate within fixed member 16. When cylinder 161 rotates, it synchronously drives cam 164 to rotate. When cam 164 rotates, it intermittently squeezes roller frame 166 at one end of reciprocating rod 165. After being squeezed, roller frame 166 drives reciprocating rod 165 to push horizontal frame 14. When horizontal frame 14 is pushed, it can move horizontally on center rod 12. That is, center rod 12 can either rotate with center rod 12 or move horizontally on center rod 12. The spray unit includes a spray box 17, a delivery pipe 171 for supplying fermentation liquid to the spray box 17 is provided on one side of the spray box 17, and multiple sets of symmetrically arranged spray nozzles 172 are opened on the central rod 12.
