Description

Technical Field

[0001] The present invention relates to the technical field of psicose fermentation, and in particular to fermentation equipment and a fermentation process for psicose processing. Background Art

[0002] Allulose is a rare sugar with many special functions such as regulating body fat accumulation, preventing nerves and treating neurological diseases. It is of great significance in the fields of health food and medical treatment. Its fermentation preparation mainly depends on the catalytic action of D-psicose-3-epimerase (DPE), which can catalyze the isomerization reaction of fructose and convert it into allulose.

[0003] For example, the patent publication number disclosed on the China Patent Network is: CN218710442U, and the patent name is: A fermentation device for batch production of D-psicose, comprising a fermentation cylinder and a sealing sleeve, wherein a second fastening bolt is installed on one side of the lower part of the fermentation cylinder, and a limiting plate is movably sleeved on the inner side of the second fastening bolt. The fermentation device for batch production of D-psicose can be used to remove the limiting plate from the lower part of the fermentation cylinder by rotating the second fastening bolt, and the second fastening bolt is rotated and taken out from the inside of the fermentation cylinder, and the sampling plate is rotated at the same time, so that an opening is formed between the sampling groove provided inside the sampling plate and the sealing sleeve, and the fermentation flow inside the fermentation cylinder flows to the inside of the sealing sleeve, and the sampling plate is pulled out downward, and the sealing sleeve is exposed to the outside, and the upper part of the sampling plate blocks the inside of the fermentation cylinder, so that when it is necessary to observe the fermentation effect of the fermented material inside the fermentation cylinder, the sealing inside the fermentation cylinder is increased.

[0004] However, the height of the stirring blades of the existing fermentation equipment is fixed, resulting in that during the stirring process, only the materials near the stirring blades can be effectively stirred. The vortex water flow generated by the high-speed rotating stirring blades is mainly concentrated in the lower layer, while the materials in the upper layer may not be fully mixed due to insufficient water flow power. Uneven stirring will lead to uneven distribution of allulose nutrients during the fermentation process, thereby affecting the growth and metabolism of allulose microorganisms and ultimately reducing the fermentation efficiency.

[0005] In addition, during the continuous high-speed rotation of the stirring blades, friction will occur with the fermentation medium, causing wear of the stirring blades. The worn stirring blades will not only reduce the stirring effect, but may also introduce impurities, affecting the quality of the fermentation product. At the same time, the high-speed rotating stirring blades require a lot of energy, increasing the operating cost of the fermentation process.

[0006] Finally, the jacket of the existing fermentation equipment can only allow one-way flow of water, resulting in insufficient temperature exchange and heat exchange. The water temperature in the jacket may be too high or too low, and the temperature difference between the water and the fermentation medium is large, which is not conducive to uniform temperature transfer. The uneven temperature distribution will affect the growth rate and metabolic activity of microorganisms, and thus affect the fermentation efficiency and product quality.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, a fermentation device and a fermentation process for processing allulose provided by the present invention include a tank body 1; A jacket 2 is welded on the surface of the tank body 1 and used for heating; A stirring structure 3 is arranged inside the tank body 1, and a spoiler structure 5 is arranged on the surface of the stirring structure 3 through a transmission structure 4. The stirring structure 3 can use the transmission structure 4 to change the spacing of the spoiler structure 5 and destroy the dynamic coordination of the stirring liquid during rotation. An oscillation structure 6 is arranged at the bottom of the tank body 1. A linkage structure 7 for connecting the oscillation structure 6 with the stirring structure 3 is arranged at the bottom of the tank body 1. During the operation of the stirring structure 3, the linkage structure 7 can be used to drive the oscillation structure 6 to vertically rise and fall and oscillate.

[0032] refer to Figure 2 The stirring structure 3 includes a transmission motor 8 fixedly connected to the top of the tank body 1, and the output end of the transmission motor 8 is fixedly connected to a transmission rod 9. The bottom end of the transmission rod 9 passes through the tank body 1 and extends to the bottom of the tank body 1. The surface of the transmission rod 9 is fixedly connected to an impeller 10 located inside the tank body 1. The transmission motor 8 can use the transmission rod 9 to drive the impeller 10 to rotate. The transmission structure 4 is arranged on the surface of the transmission rod 9, and the spoiler structure 5 is located on both sides of the transmission rod 9.

[0033] As a technical optimization solution of the present invention, the transmission motor 8 drives the transmission rod 9 and the impeller 10 to rotate, thereby achieving sufficient stirring of the fermentation liquid, improving the mixing uniformity of the fermentation liquid, and facilitating the growth and metabolism of microorganisms.

[0034] refer to Figure 3 The spoiler structure 5 includes an extension plate 11, which is arranged on both sides of the transmission rod 9 through the transmission structure 4. They move with the rotation of the transmission rod 9 and are the main components that carry the spoiler 13 for spoiler treatment. The transmission structure 4 is responsible for converting the rotational movement of the transmission rod 9 into the relative movement of the extension plate 11, so that the extension plate 11 can dynamically change its position during the stirring process, thereby enhancing the spoiler effect. Both sides of the surface of the extension plate 11 are fixedly connected with an adjustment rod 12, which not only provides a mounting point for the spoiler 13, but also allows the position of the spoiler 13 to be fine-tuned through a threaded assembly. The spoiler 13 is fixedly installed on the surface of the adjustment rod 12 through a threaded assembly, aiming to generate turbulence during the stirring process, thereby breaking the static layer of the liquid and promoting mixing between different layers of liquid.

[0035] As a technical optimization scheme of the present invention, the spoiler 13 moves toward each other under the drive of the transmission structure 4, and the stirring liquid is disturbed, which further destroys the dynamic coordination of the liquid, improves the stirring efficiency and mixing uniformity, and helps the fermentation process. The spoiler structure 5 can significantly enhance the mixing effect of the stirring liquid, so that the nutrients in the fermentation liquid are more evenly distributed. The optimized spoiler structure 5 can break the static layer and promote the full contact between microorganisms and nutrients, thereby improving the fermentation rate and product quality.

[0036] refer to Figure 3 The transmission structure 4 includes screw sleeves 15 respectively sleeved on both sides of the surface of the transmission rod 9. The surface of the transmission rod 9 is provided with a reciprocating thread groove 16. The number of the reciprocating thread grooves 16 is two sections and they are symmetrically arranged. The screw sleeve 15 sleeved on the surface of the transmission rod 9 is threadedly connected to the transmission rod 9 through the reciprocating thread groove 16. Both sides of the front and back sides of the screw sleeve 15 are movably connected with a crank 17 through a pin shaft. The crank 17 extends away from the side of the screw sleeve 15 to the outside of the extension plate 11 and is movably connected to the extension plate 11 through a pin shaft.

[0037] As a technical optimization solution of the present invention, by utilizing the threaded connection between the reciprocating thread groove 16 and the screw sleeve 15, the up and down movement of the screw sleeve 15 is realized when the transmission rod 9 rotates, and through the connection between the crank 17 and the extension plate 11, the movement of the screw sleeve 15 is converted into the movement of the spoiler structure 5, thereby realizing the adjustment of the spacing of the spoiler structure 5 and enhancing the stirring effect.

[0038] refer to Figure 3The extension structure 14 includes a swing plate 18, which is movably connected to both sides of the surface of the extension plate 11 through a pin shaft. The swing plate 18 can swing around the pin shaft at a certain angle, thereby changing its position relative to the extension plate 11. Each swing plate 18 is fixedly connected to a force-bearing rod 19 on one side close to the extension plate 11. These force-bearing rods 19 are key components for transmitting force. They transmit the force from the extrusion rod 20 of the crank 17 to the swing plate 18, causing it to swing. An extrusion rod 20 is fixedly connected to the outer side of the crank 17. This rod extends to the outer side of the force-bearing rod 19. When the crank 17 moves with the movement of the screw sleeve 15, the extrusion rod 20 will move accordingly and may come into contact with the force-bearing rod 19. When the extrusion rod 20 comes into contact with the force-bearing rod 19, When the rod 19 contacts, it will apply a force to the force-bearing rod 19, and this force will cause the swing plate 18 to swing around the pin shaft. This swinging action will change the relative position of the spoiler 13, thereby further increasing the spoiler effect. The surface of the extension plate 11 is fixedly connected to a vertical plate 21 located on the inner side of the force-bearing rod 19. This vertical plate 21 provides a stable support point for the spring plate 22. The surface of the vertical plate 21 is fixedly connected to an elastic plate 22. The side of the elastic plate 22 away from the vertical plate 21 contacts the surface of the force-bearing rod 19. The elastic plate 22 is elastic. When the force-bearing rod 19 is squeezed and moved by the extrusion rod 20, the elastic plate 22 will be compressed. When the force-bearing rod 19 is separated from the extrusion rod 20, the elastic plate 22 will use its elastic restoring force to push the force-bearing rod 19 to reset.

[0039] As a technical optimization scheme of the present invention, the expansion structure 14 is used through the swing plate 18 and the force-bearing rod 19 components to further expand the disturbance area during the movement of the crank 17, thereby improving the disturbance effect and enhancing the mixing uniformity of the stirred liquid. Through the swing of the swing plate 18, the spoiler 13 can cover a larger area, thereby more effectively stirring and mixing the fermentation liquid. The dynamically adjusted spoiler structure 5 can break the static layer in the fermentation liquid, promote mixing and exchange between fermentation liquids at different levels, and thus improve the fermentation efficiency.

[0041] As a technical optimization solution of the present invention, the support ring 23 and the guide rod 24 are provided to provide stable support and guidance for the screw sleeve 15, thereby ensuring the smooth sliding of the screw sleeve 15 on the transmission rod 9, avoiding the shaking and deviation of the screw sleeve 15 during the movement, and improving the stability and reliability of the equipment.

A driving structure 29 is arranged inside the base 25, and the driving structure 29 can control the sleeve 27 to swing and push the tank body 1 to rise and fall vertically when it contacts the ground.

[0043] As a technical optimization solution of the present invention, by setting the base 25, the movable block 26, the sleeve plate 27 and the roller 28 components, the vertical lifting and shaking of the tank body 1 is realized, which helps to promote the material exchange and microbial activity in the fermentation liquid, and improves the fermentation efficiency and product quality.

[0044] refer to Figure 8 The driving structure 29 includes a screw rod 30 movably connected to the inside of the base 25 through a bearing. The screw rod 30 is located on the inner side of the sleeve plate 27. The surface of the screw rod 30 is threadedly connected to a transmission block 31 located on the inner side of the sleeve plate 27. Both sides of the transmission block 31 are fixedly connected to a pull rod 32 located inside the sleeve plate 27. The pull rod 32 is slidably connected to the sleeve plate 27.

In addition, the structure is simple and effective, and the linkage between the stirring structure 3 and the oscillation structure 6 is achieved, thereby improving the overall performance of the equipment.

The active bevel gear 33 and the driven bevel gear 34 in the linkage structure 7 are meshed with each other. When the transmission rod 9 rotates, it will drive the screw 30 to rotate synchronously. The rotation of the screw 30 causes the transmission block 31 on its surface to move inside the sleeve plate 27, and then the sleeve plate 27 is pushed to swing through the pull rod 32. When the sleeve plate 27 swings to contact the ground, it will push the tank body 1 to perform vertical lifting and oscillation.

This structure helps to enhance the heat transfer efficiency of the jacket 2, improve the heating uniformity of the fermentation liquid, and further improve the fermentation efficiency and product quality.

[0053] The working principle and use process of the present invention are as follows: When the fermentation process starts, the transmission motor 8 is first started. As the power source of the entire stirring system, the transmission motor 8 starts to work, and the output end of the transmission motor 8 drives the transmission rod 9 to rotate, and the transmission rod 9 then drives the impeller 10 at its bottom end to rotate in the tank body 1. The rotation of the impeller 10 produces a stirring effect, so that the allulose liquid in the tank body 1 begins to mix. At the same time, the screw sleeve 15 on the surface of the transmission rod 9 starts to move up and down along the transmission rod 9 due to the threaded connection with the reciprocating thread groove 16 on the surface of the transmission rod 9. The movement of the screw sleeve 15 drives the extension plate 11 and the spoiler 13 thereon to move toward or away from each other through the crank 17. During the movement, the spoiler 13 exerts pressure on the tank body 1. The liquid in the cylinder 15 is disturbed to destroy the dynamic coordination of the liquid and improve the stirring effect. The swing plate 18 on the surface of the extension plate 11 squeezes the force-bearing rod 19 through the squeezing rod 20 during the process of the crank 17 following the screw sleeve 15 to move inward. The swing plate 18 is squeezed and swings toward each other and further expands the disturbance area to enhance the disturbance effect. The bottom end of the transmission rod 9 is fixed with an active bevel gear 33, and the active bevel gear 33 and the driven bevel gear 34 are meshed with each other. Therefore, the rotation of the transmission rod 9 will drive the multiple screws 30 to rotate synchronously. The rotation of the screw 30 causes the sleeve plate 27 to rotate through the transmission block 31 and the pull rod 32. The base 25 swings internally, and when the sleeve 27 swings, the roller 28 on its outer side contacts the ground, causing the tank body 1 to generate a vertical lifting vibration. This vibration helps to further improve the mixing effect of the liquid in the tank body 1, and can balance the flow area of ​​the heated liquid in the jacket 2, and also helps the fermentation process of allulose. When the screw sleeve 15 moves, the cross plate 39 on its top extends through the base 25 to the inner side of the driving plate 37, and the push rod 40 on the cross plate 39 is slidably connected with the groove 38 on the surface of the driving plate 37. When the screw sleeve 15 moves up and down, the cross plate 39 drives the push rod 40 to move in the driving plate 37. The moving plate 37 slides inside and squeezes the driving plate 37 through the groove 38. After the driving plate 37 is squeezed, it carries the bracket 35 and slides vertically on the surface of the tank body 1. The vertical sliding of the bracket 35 not only enhances the stability of the tank body 1, but also intermittently vibrates and knocks the jacket 2 through the knocking rod 42. This knocking helps to prevent scaling or clogging inside the jacket 2 and maintain heating efficiency. Under the combined effects of stirring, shaking and heating, the allulose liquid in the tank body 1 continues to ferment. During the fermentation process, the microorganisms use the nutrients in the liquid to carry out metabolic activities to produce the required allulose products.

[0054] In summary: the fermentation equipment and fermentation process for allulose processing provide an efficient and uniform fermentation environment for allulose processing by integrating multiple functions such as heating, stirring, turbulence and shaking. At the same time, the shaking structure 6 enhances the material exchange and microbial activity in the fermentation process, which is beneficial to improving the fermentation efficiency and product quality.
