Description

Technical Field

[0001] This invention relates to the field of jujube processing, and in particular to a fermentation and enzymatic hydrolysis device for jujube. Background Technology

[0002] Sour jujubes are rich in various vitamins, minerals, and active ingredients, possessing high nutritional and medicinal value and broad application prospects in the food and health product industries. To enhance the flavor of sour jujube products, fermentation and enzymatic hydrolysis can effectively break down some of the complex components in sour jujubes, thereby producing a unique flavor, improving the bioavailability of nutrients, and enhancing product quality.

[0003] However, the techniques commonly used for enzymatic hydrolysis of jujube fermentation often have some problems in daily use. With the development of science and technology, technicians in related fields have also made a lot of optimizations to the techniques used for enzymatic hydrolysis of jujube fermentation. For a more accurate comparison, Chinese patent CN118240655A discloses a fermentation enzymatic hydrolysis device and method, including a motor, processing box, fermentation box, collection box, feed inlet, and gravity sensor. In use, the gravity sensor can calculate the difference between the current weight of the fermentation reaction vehicle and the gravity when fully loaded. When the gravity difference is less than the amount that the crushing tank can process at one time, the feed inlet will deliver an amount close to the gravity difference. When the gravity difference reaches the full load, the device will stop running and release an alarm signal. After the staff replaces the fermentation reaction vehicle, the device will be restarted. At the same time, the gravity sensor will also control the enzyme storage box to deliver a quantitative amount of enzyme according to the amount of jujubes delivered at one time, so that the staff does not need to replace the fermentation reaction vehicle according to the release of the alarm signal, increasing the flexibility of the device.

[0004] However, the above-mentioned techniques for enzymatic hydrolysis of jujube fermentation have some shortcomings in practical application: The above-mentioned device crushes the jujubes that enter the crushing tank by cooperating with the crushing tank and the crushing agitator. After crushing, the crushing tank is driven to rotate so that the feed port becomes the discharge port. In other words, the above technology fails to guide the crushed jujubes in the crushing tank in time so that the jujubes can be discharged. In particular, the crushed jujubes located in the corner of the crushing tank are difficult to detach from the crushing tank by themselves, which can easily cause blockage in the crushing tank.

[0005] Secondly, the above-mentioned technology drives the collection box and the enzymes and jujubes inside to slide back and forth horizontally to drive the jujubes and enzymes to mix thoroughly. However, since it only drives the jujubes and enzymes to shake and mix by sliding back and forth horizontally in the collection box, as the jujubes and enzymes in the collection box gradually approach full capacity, the space in the collection box for shaking the jujubes and enzymes will also gradually shrink accordingly, resulting in a decrease in the shaking efficiency of the jujubes and enzymes, and thus a decrease in the mixing efficiency.

[0006] Therefore, based on the above-mentioned viewpoints, there is still room for improvement in the existing technologies used for the enzymatic hydrolysis of jujube fermentation. Summary of the Invention

[0013] Preferably, the drive assembly includes a rotating shaft that passes through the crushing disc, grinding disc, and rotating block. After the rotating shaft rotates out of the pretreatment chamber, it connects to a drive unit located within the reactor.

[0014] Preferably, the reaction end includes a mixing cylinder located at the end of the guide tube away from the pretreatment chamber. The bottom of the mixing cylinder and the reaction vessel are hinged together by a ball joint. An upwardly extending driven guide rod is connected to the mixing cylinder, and a drive lever connected to the rotation of the guide tube is sleeved on the driven guide rod.

[0015] Preferably, the mixing cylinder is spaced apart from the guide tube at one end, and a guide groove is formed on the drive plate corresponding to the driven guide rod. An adjusting spring is connected between the driven guide rod and the guide groove.

[0016] Preferably, the guide tube is inclined downward and extends upward to form a branch tube. The guide tube and the branch tube extend downward together to connect with the mixing cylinder. The branch tube is connected to an enzyme storage chamber fixed on the reaction vessel.

[0017] Preferably, the mixing cylinder, the guide pipe, and the branch pipe are all limited by a stirring shaft, and the stirring shaft is limited by an auger blade located between the guide pipe and the branch pipe. The auger blade slides and fits against the inner wall of the common extension section of the guide pipe and the branch pipe.

[0018] Preferably, a driven gear connected to a drive lever is rotatably sleeved on the guide tube, a drive gear meshes with the driven gear, and a transmission shaft with a rotation limit on the guide tube is connected to the middle of the drive gear. The transmission shaft and the rotating shaft are connected by a synchronous belt.

[0019] In summary, this application includes at least one of the following beneficial technical effects: I. This invention achieves further refinement of crushed jujubes through the cooperation of the crushing disc, the fixing sleeve, and the grinding disc, which helps to increase the contact area between the jujubes and the reaction enzymes. At the same time, the rotating block and several cleaning blades at the bottom of the pretreatment chamber can guide and discharge the crushed jujubes falling to the bottom of the pretreatment chamber in a timely manner, avoiding the problem of blockage caused by failure to discharge them in time in the pretreatment chamber.

[0021] Third, this invention drives the mixing cylinder to rotate in both forward and reverse directions through the mutual cooperation between the driving gear, the transmission gear and the driven gear, thereby guiding the jujube and enzyme mixture in the mixing cylinder to continuously form vortices in both forward and reverse directions, effectively improving the mixing efficiency of jujube and enzyme.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 The embodiments of the present invention will be described in detail below.

[0033] This application discloses a fermentation enzymatic hydrolysis device for jujubes. This device is mainly used in the fermentation enzymatic hydrolysis process of jujubes, achieving the effect of crushing the jujubes and thoroughly and uniformly mixing the crushed jujubes with the enzymes. Specifically, during the crushing process, multi-layer crushing further refines the jujubes, increasing the contact area between the jujubes and the enzymes, effectively improving the contact and mixing efficiency between them. Furthermore, this application also guides the crushed jujubes and enzymes to contact and mix earlier through the cooperation between the pretreatment end and the reaction end, further enhancing the contact and mixing efficiency between them.

[0034] Example 1: Refer to Figure 1As shown, a fermentation and enzymatic hydrolysis device for jujube includes a hollow reactor 1. The reactor 1 contains a pretreatment end 2 for crushing jujube particles and a corresponding reaction end 3. After a measured quantity of jujubes is fed into the reactor 1, the jujubes first come into contact with the pretreatment end 2, where they are crushed and pretreated. Then, the jujubes are guided by the pretreatment end 2 to the reaction end 3 for fermentation and enzymatic hydrolysis.

[0035] Reference Figure 2 and Figure 3 As shown, this is the pretreatment end 2 used for crushing jujube granules; specifically, the pretreatment end 2 includes: The pretreatment chamber 20 is fixedly located within the reactor 1, and the pretreatment chamber 20 contains at least the following components, arranged sequentially from top to bottom: A crushing component 21 is used to crush several jujubes that have entered the pretreatment chamber 20.

[0036] Discharge assembly 22 guides the crushed jujubes out of pretreatment chamber 20.

[0037] And a drive assembly 23 for driving the crushing assembly 21 and the discharge assembly 22.

[0038] After the jujubes to be processed enter the pretreatment chamber 20, they will pass through the crushing component 21 and the discharge component 22 in sequence. During the rotation of the driven component 23, the crushing component 21 applies extrusion and shearing forces to the incoming jujubes to guide them to be crushed. After the crushed jujubes fall to the discharge component 22, the rotating discharge component 22 applies centrifugal force to drive them out of the pretreatment chamber 20 in a timely manner, so as to avoid the jujubes remaining in the pretreatment chamber 20 after crushing, which can easily cause blockage.

[0039] Reference Figure 2 and Figure 3 As shown, the crushing component 21 is used to crush a number of jujubes entering the pretreatment chamber 20. Specifically, the crushing component 21 includes a crushing disc 210 that is rotatably limited within the pretreatment chamber 20. The outer edge of the crushing disc 210 is fitted with a fixed sleeve 211 that is fixedly connected to the pretreatment chamber 20. Corresponding toothed surfaces are formed between the opposite sides of the crushing disc 210 and the fixed sleeve 211. When the jujubes fall into the pretreatment chamber 20 between the two toothed surfaces of the crushing disc 210 and the fixed sleeve 211, the crushing disc 210 will be driven by the driving component 23 to rotate relative to the fixed sleeve 211, applying a rotational shearing force to the jujubes between the crushing disc 210 and the fixed sleeve 211, causing the jujubes to move between the two toothed surfaces, so as to squeeze and shear the jujubes to crush them.

[0040] Reference Figures 2 to 4As shown, a grinding disc 212 is coaxially connected to the lower side of the crushing disc 210. The outer edge of the grinding disc 212 is also set as a toothed surface corresponding to the fixing sleeve 211. The outer diameter of the grinding disc 212 gradually increases from top to bottom, and the gap between it and the fixing sleeve 211 gradually decreases accordingly. During the process of the grinding disc 212 being driven by the driving component 23 to rotate in the fixing sleeve 211, it has closer contact with the jujube, which can further increase the fineness of the jujube, facilitate the close contact between the enzyme and the jujube, and improve the fermentation and enzymatic hydrolysis rate.

[0041] Reference Figures 2 to 4 As shown, the discharge component 22 is used to guide the crushed jujubes out of the pretreatment chamber 20. Specifically, the discharge component 22 includes a rotating block 220 coaxially connected to the lower side of the grinding disc 212. The rotating block 220 is spaced a certain distance from the pretreatment chamber 20 to facilitate the crushed jujubes falling to the bottom of the pretreatment chamber 20. At the same time, the outer edge of the rotating block 220 is connected to a cleaning blade 221 that abuts against the inner wall of the pretreatment chamber 20. During the rotation of the rotating block 220 and the cleaning blade 221, the jujubes at the bottom of the pretreatment chamber 20 are rotated and displaced. The centrifugal effect generated by the rotating block 220 and the cleaning blade 221 allows the jujubes to be discharged from the pretreatment chamber 20 in a timely manner. A guide pipe 222 is installed on the lower side of the pretreatment chamber 20 corresponding to the rotating block 220 and the cleaning blade 221, and the pretreated jujubes are guided to the reaction end 3 for fermentation and enzymatic hydrolysis through the guide pipe 222.

[0042] Reference Figures 2 to 4 As shown, this is the drive assembly 23 used to operate the crushing assembly 21 and the discharge assembly 22. Specifically, the drive assembly 23 includes a rotating shaft 230 that passes through the crushing disc 210, the grinding disc 212, and the rotating block 220. The rotating shaft 230 rotates out of the pretreatment chamber 20 and connects to a drive unit 231 located within the reactor 1. The drive unit 231 drives the rotating shaft 230 to rotate, which in turn causes the rotating block 220, the grinding disc 212, and the crushing disc 210 to rotate within the pretreatment chamber 20. This process crushes and pre-treats the jujubes entering the pretreatment chamber 20 and guides the crushed jujubes out, preventing them from accumulating in the pretreatment chamber 20 and causing blockages.

[0043] Reference Figure 5 and Figure 6As shown, the reaction end 3 is used to guide the pretreated jujube and enzyme to mix and react. Specifically, the reaction end 3 includes a mixing cylinder 30 located at the end of the guide tube 222 away from the pretreatment chamber 20. Both the mixing cylinder 30 and the bottom of the reaction vessel 1 have discharge channels, which are normally closed. A ball-head rod is connected to the bottom of the mixing cylinder 30. The ball end of the ball-head rod is fitted with a base that is fixedly connected to the reaction vessel 1. An upwardly extending driven guide rod 31 is connected to the upper end of the mixing cylinder 30. A drive plate 32 is sleeved on the driven guide rod 31. A rotating sleeve is rotatably sleeved on the guide tube 222.

[0044] In use, the jujubes are crushed and refined in the pretreatment chamber 20 and then transported to the mixing drum 30 through the guide pipe 222. During the process of transporting the crushed jujubes to the mixing drum 30, the enzymes to be reacted are simultaneously transported to the mixing drum 30. The rotation of the drive plate 32 drives the driven guide rod 31 and the mixing drum 30 to rotate, generating a centrifugal effect. During the rotation of the mixing drum 30 and the driven guide rod 31, the centrifugal effect guides the jujubes and enzymes in the mixing drum 30 to rotate synchronously, so as to promote their uniform mixing and complete the fermentation and enzymatic hydrolysis process of the jujubes.

[0045] Furthermore, referring to Figure 5 and Figure 6 As shown, the mixing cylinder 30 is spaced apart from the guide tube 222 at one end. A guide groove is formed on the drive plate 32 corresponding to the driven guide rod 31. An adjusting spring 33 connects the driven guide rod 31 and the guide groove, allowing the mixing cylinder 30 and the driven guide rod 31 to slide along the guide groove during rotation. In use, after the mixing cylinder 30 and the driven guide rod 31 are rotated, the bottom of the mixing cylinder 30 is rotatably connected to the base via a ball joint. During rotation, it is constantly affected by centrifugal force, causing the driven guide rod 31 and the entire mixing cylinder 30 to slide away from the central guide tube 222 along the guide groove, with the ball joint as the axis. The swinging and sliding of the driven guide rod 31 synchronously causes the adjusting spring 33 to continuously deform under force (first under the centrifugal force of the rotating mixing cylinder 30 towards the direction away from the guide tube 222). The stretched deformation generates a rebound force that drives the mixing cylinder 30 to swing back towards the guide tube 222. Then, the centrifugal force of the rotating mixing cylinder 30 drives the stretched deformation again, and so on. Under the combined action of centrifugal force and the elastic restoring force of the adjusting spring 33 after deformation, the mixing cylinder 30 is driven to swing continuously during the rotation. Through the combined motion of rotation and swing of the mixing cylinder 30, the enzyme and jujube in the mixing cylinder 30 are guided to mix quickly and evenly, which helps to improve the fermentation and enzymatic hydrolysis effect of jujube.

[0046] Furthermore, referring to Figures 5 to 8As shown, at least two drive levers 32, driven guide rods 31, guide chutes, and adjusting springs 33 are provided, symmetrically distributed on both sides of the guide tube 222. During the process of the mixing drum 30 swinging to either side along the guide chutes under centrifugal force (it should be noted that this is the process where the direction of the tangential force exerted by the centrifugal force on the mixing drum 30 during rotation is in the same radial direction as the paths of the two guide chutes), the adjusting spring 33 on one side of the guide tube 222 will be in a state of tension deformation, while the other side will be in a state of compression deformation. After both adjusting springs 33 are deformed, they will generate elastic restoring force, driving the driven guide rod 31 and the mixing drum 30 to swing back as a whole. This makes the continuous reciprocating oscillation motion of the mixing drum 30 during rotation more stable, thereby promoting thorough mixing of the materials within.

[0047] Reference Figures 5 to 7 As shown, the guide pipe 222 is inclined downwards and extends upwards to form a branch pipe 34. The guide pipe 222 and the branch pipe 34 extend downwards together to connect with the mixing cylinder 30. The branch pipe 34 is connected to an enzyme storage chamber 35 fixed on the reaction vessel 1. After the crushed and refined jujubes are discharged from the pretreatment chamber 20 and enter the guide pipe 222, they will automatically fall downwards along the inclined guide pipe 222 to the reaction end 3 due to their own gravity. During this process, the reaction enzymes (usually pectinase, cellulase, etc.) in the enzyme storage chamber 35 are controlled by existing technologies such as metering valves to fall from the branch pipe 34 into the guide pipe 222 and fall synchronously with the jujubes to the reaction end 3, guiding the refined jujubes and reaction enzymes to come into natural contact and mix.

[0048] After the refined jujubes and the reaction enzyme are initially mixed in the guide tube 222, they enter the mixing cylinder 30. Due to the inclined design of the guide tube 222, the crushed and refined jujubes can slide naturally into the mixing cylinder 30 at a relatively uniform speed. During this process, the enzyme in the enzyme storage chamber 35 is also introduced into the guide tube 222 through the branch tube 34, guiding the crushed and refined jujubes and enzymes to come into contact and mix in advance, thereby improving the mixing efficiency of jujubes and enzymes.

[0049] Reference Figure 7 As shown, a stirring shaft 36 is provided between the mixing cylinder 30, the guide pipe 222, and the branch pipe 34. An auger blade 360 ​​is positioned between the guide pipe 222 and the branch pipe 34. The auger blade 360 ​​slides and fits against the inner wall of the common extension section of the guide pipe 222 and the branch pipe 34, and extends a portion to the connection port of the guide pipe 222 and the branch pipe 34. A transmission frame 372 connected to the stirring shaft 36 is connected to the rotating sleeve to drive the stirring shaft 36 and the auger blade 360 ​​to rotate synchronously with the drive plate 32, thereby driving the crushed and refined jujube and enzyme in the guide pipe 222 to contact and mix evenly beforehand.

[0050] Reference Figure 7 and Figure 8 As shown, a driven gear 37 is coaxially connected to the rotating sleeve and rotatably mounted on the guide tube 222. A drive gear 370 meshes with the driven gear 37. A transmission shaft 371, which is rotatably limited on the guide tube 222, is connected to the middle of the drive gear 370. The transmission shaft 371 and the rotating shaft 230 are connected by a synchronous belt. The rotation of the rotating shaft 230 drives the transmission shaft 371 and the drive gear 370 to rotate synchronously via the synchronous belt. The rotation of the drive gear 370 drives the driven gear 37 to rotate, thereby driving the entire mixing cylinder 30 to rotate and guide the jujube and enzymes inside to fully contact and mix.

[0051] Example 2: Refer to Figures 5 to 8 As shown, based on Embodiment 1, in order to improve the mixing effect of the crushed jujube and enzyme in the mixing cylinder 30, the drive gear 370 is configured as an incomplete gear. The driven gear 37 is also meshed with transmission gears 38 symmetrically distributed on both sides of the guide tube 222, corresponding to the drive gear 370. The transmission gears 38 are also configured as incomplete gears corresponding to the drive gear 370. The transmission gears 38 are limited to the lower side of the enzyme storage chamber 35 by a rotating wheel rod 380. The end of the rotating wheel rod 380 away from the transmission gear 38 is rotatably limited to the enzyme storage chamber 35 by a spiral spring 381. One end of the spiral spring 381 is connected to the limiting position of the rotating wheel rod 380, and the other end is connected to the limiting position of the enzyme storage chamber 35. Initially, the toothed sections on the drive gear 370 and the transmission gear 38 are simultaneously engaged with the driven gear 37, while the spiral spring 381 is in its normally extended state.

[0052] In use, since both the transmission gear 38 and the drive gear 370 are incomplete gears and symmetrically distributed relative to the guide tube 222 (that is, the tooth segments on the drive gear 370 and the transmission gear 38 will intermittently drive the driven gear 37 to rotate and adjust), when the drive gear 370 drives the driven gear 37 to rotate, the transmission gear 38 will also be driven to rotate synchronously. The rotation of the transmission gear 38 drives the rotating wheel rod to rotate, and drives the spiral spring 381 to coil and tighten. After the drive gear 370 and the driven gear 37 disengage, the coiled spiral spring 381 needs to return to normal extension, which will drive the rotating wheel rod 380 and the transmission gear 38 to rotate in the opposite direction. The reverse rotation of the transmission gear 38 drives the driven gear 37, the drive plate 32, the driven guide rod 31, the mixing cylinder 30, the stirring shaft 36, and the auger blade 360 ​​to rotate synchronously. During this process, since the mixing cylinder 30 The materials (jujubes and enzymes) inside the mixing drum 30 initially form a positive vortex due to the centrifugal force exerted by the forward rotation of the mixing drum 30. Even after the drive gear 370 and the driven gear 37 disengage, the materials inside the mixing drum 30 still tend to rotate in the forward direction. When the mixing drum 30 is driven to rotate in the opposite direction by the transmission gear 38, the materials rotating in the forward direction will first generate relative displacement with the mixing drum 30 rotating in the opposite direction, and then be driven by the mixing drum 30 to rotate in the opposite direction. This process is repeated, and by repeatedly driving the mixing drum 30 to rotate in the forward and reverse directions, relative displacement is generated between the materials inside the mixing drum 30 and the inner wall of the mixing drum 30. This effectively avoids the problem of jujubes not being able to contact the enzymes in time due to continuous mixing in the same direction, leaving the area in the corner of the mixing drum 30. This improves the contact efficiency of jujubes and enzymes, allowing them to be fully and evenly mixed, which helps with the subsequent fermentation and enzymatic hydrolysis of jujubes and enzymes, and improves product quality.

[0053] Furthermore, to improve the mixing efficiency of the materials inside the mixing drum 30, the stirring shaft 36 extends downward into the mixing drum 30, and a stirring frame 373 located inside the mixing drum 30 is connected thereon. During the process of the mixing drum 30 being driven to rotate in the opposite direction, the transmission frame 372, the stirring shaft 36, and the stirring frame 373 are simultaneously driven to rotate in the opposite direction, so that the stirring frame 373 rotates in the opposite direction relative to the forward-rotating vortex inside the mixing drum 30 in advance, thereby breaking the inherent path of the forward-rotating vortex and increasing the mixing efficiency of the materials inside the mixing drum 30.

[0054] During operation: First, a quantitative amount of jujubes is fed into the pretreatment chamber 20 for crushing and pretreatment. After the jujubes are crushed, they are promptly discharged from the pretreatment chamber 20 by the discharge component 22 to avoid excessive accumulation of jujubes at the bottom of the pretreatment chamber 20.

[0055] Step 2: After the jujube is crushed and refined, it is transported to the reaction end 3 by the guide tube 222. During this process, the reaction enzyme is driven to contact and mix in advance in the guide tube 222.

[0056] Step 3: After crushing, the jujube and the enzyme are transported to the reaction end 3 through the guide tube 222. The jujube and the enzyme are then guided to contact and mix again through the reaction end 3, so that the crushed jujube and the enzyme are fully and evenly mixed together.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and not restrictive.
