Description

Technical Field

[0001] The present invention relates to the technical field of turning devices, and particularly to a turning device for solid fermentation of probiotics. Background Art

[0002] As is well known, turning is a common and important operation in the solid or liquid fermentation of probiotics. Since the solid medium is usually a solid substrate such as bran, rice bran, etc., the materials are piled up together, and the distribution of oxygen, temperature, humidity, etc. may be uneven. Turning can make the materials fully contact with air, meet the oxygen demand of probiotics, and also helps to dissipate heat, avoiding the inhibition of probiotic growth due to excessive local temperature. It can also make the distribution of nutrients more uniform, enabling the probiotics to grow more evenly and metabolize more stably, improving the fermentation effect and product quality.

[0003] In particular, the precise control of the solid fermentation process of probiotics plays an important role in product quality, activity and stability, and the turning link is the key of the key. However, most of the existing traditional turning devices for solid fermentation of probiotics adopt simple single-paddle stirring or manual turning. The former is prone to uneven material mixing and heat accumulation, affecting the growth of probiotics; the latter is inefficient and difficult to ensure hygienic standards, especially when facing different strain characteristics and complex and changeable fermentation processes, the problems are more prominent. For example, some strains with large fluctuations in oxygen demand require intermittent turning to adapt to their special breathing rhythm; in some large-scale fermentation scenarios, continuous turning is crucial for timely dissipating heat and maintaining a stable fermentation environment; when the material is piled up thickly, the lack of the ability to precisely turn in layers leads to oxygen deficiency and caking of the bottom layer materials, and excessive disturbance of the upper layer materials.

[0004] Therefore, the present invention proposes a turning device for solid fermentation of probiotics equipped with a double-helix stirring structure and an annular conveyor belt type turning structure to ensure continuous and uniform turning of the materials, quickly dissipate heat, and can also flexibly control the material temperature by designing the stirring shaft as a hollow structure and introducing hot water or cold water as needed to ensure better solid fermentation effect of probiotics.

[0030] As Figures 2-3 shown in

[0031] As Figures 2-3Among them, the annular conveyor belt type material turning mechanism includes an annular conveyor and turning belt 502 arranged on both sides of the inner cavity of the fermentation tank 1. A plurality of turning plates 505 are fixedly arranged on the outer side of the annular circumference of the annular conveyor and turning belt 502.

[0032] As Figures 2-4 Among them, the material temperature regulating mechanism includes temperature regulating cavities with a hollow structure respectively arranged on the left spiral stirring shaft 10 and the right spiral stirring shaft 12. The bottom side of the fermentation tank 1 is fixedly connected with a first hot and cold circulating water box 17. The bottom ends of the left spiral stirring shaft 10 and the right spiral stirring shaft 12 are respectively communicated with the first hot and cold circulating water box 17. The left side of the bottom of the first hot and cold circulating water box 17 is fixedly connected with a first hot water circulating pipe 142 and a first cold water circulating pipe 152 respectively through a three-way valve 16. An instant electric water heater 14 and an air-cooled cold water machine 15 are respectively arranged on the base 2. A hot water circulating pump 141 is arranged on the instant electric water heater 14. The output end of the hot water circulating pump 141 is connected with the first hot water circulating pipe 142. The input end of the hot water circulating pump 141 is connected with the first hot and cold circulating water box 17 through a second hot water circulating pipe 143. A cold water circulating pump 151 is arranged on the air-cooled cold water machine 15. The output end of the cold water circulating pump 151 is connected with the first cold water circulating pipe 152. The input end of the cold water circulating pump 151 is connected with the first hot and cold circulating water box 17 through a second cold water circulating pipe 153. The top of the installation shell 6 is fixedly connected with a second hot and cold circulating water box 18 through a connecting seat 19. The top ends of the left spiral stirring shaft 10 and the right spiral stirring shaft 12 are respectively communicated with the second hot and cold circulating water box 18.

[0033] As Figures 4-5 Among them, a tilt - set one - way valve plate 22 is rotatably installed at the center of the inner wall of the top of the first hot and cold circulating water box 17. A spring 23 is also fixedly connected between the tilt top surface of the one - way valve plate 22 and the top - side inner wall of the first hot and cold circulating water box 17.

[0034] As Figures 3-4 Among them, first sealing bearings 21 are arranged on both sides of the inner wall of the top of the first hot and cold circulating water box 17. The bottom ends of the left spiral stirring shaft 10 and the right spiral stirring shaft 12 are sealed and rotatably installed on the first sealing bearings 21. Second sealing bearings 20 are arranged on both sides of the inner wall of the bottom of the second hot and cold circulating water box 18. The top ends of the left spiral stirring shaft 10 and the right spiral stirring shaft 12 are sealed and rotatably installed on the second sealing bearings 20.

[0035] AsFigure 2 , 4 In 4 , a plurality of turnover plates 505 are arranged equidistantly and uniformly on the circumferential circle of the annular conveyor turnover belt 502; a feed inlet 101 is provided on the left side of the top of the fermentation tank 1, and a discharge port 102 is provided on the right side of the bottom of the fermentation tank 1.

[0036] Among them, a plurality of temperature sensors 24 are provided on the inner walls on both sides of the fermentation tank 1, and a controller 25 is provided on the front of the fermentation tank 1. The controller 25 is electrically connected to the temperature sensors 24, the first motor 7, the second motor 5, the hot water circulation pump 141, the cold water circulation pump 151, the instant electric water heater 14, and the air-cooled chiller 15 for electrical control.

[0037] As Figures 1-5 shown, when the probiotic solid fermentation turnover device is used for turning over the materials in the fermentation tank 1: by setting the double-helix stirring mechanism, the driving gear 8 is driven by the first motor 7 to rotate and mesh with the driven gear 9, so as to drive the left helix stirring shaft 10 and the right helix stirring shaft 12 to rotate synchronously. The left helix stirring shaft 10 drives the left screw turnover blade 11 to rotate in a spiral manner, and the right helix stirring shaft 12 drives the right screw turnover blade 13 to move in a spiral manner. Since the spiral directions of the left screw turnover blade 11 and the right screw turnover blade 13 are set in opposite directions, when the two shafts are driven to rotate synchronously and in opposite directions, the materials will be continuously conveyed from one end of the fermentation tank 1 to the other end under the push of the spiral blades such as the left screw turnover blade 11 and the right screw turnover blade 13, and at the same time, the up-and-down spiral turning is realized to ensure that the materials are always in a moving state, which is beneficial to the uniform dissipation of the heat of the materials.

[0038] As Figures 2-4In addition, by setting up a material temperature adjustment mechanism, the spiral stirring shaft is designed as a hollow structure (i.e., there are temperature adjustment cavities inside both the left spiral stirring shaft 10 and the right spiral stirring shaft 12), so as to introduce hot water or cold water to assist in adjusting the material temperature and further optimize the fermentation environment. Specifically, when adjusting the temperature: when the temperature needs to be raised, the instant electric water heater 14 and the hot water circulation pump 141 can work. The hot water circulation pump 141 works to pump the hot water heated in the instant electric water heater 14 through the first hot water circulation pipe 142 and the three-way valve 16 into the first hot and cold circulation water box 17. Subsequently, the hot water is introduced into the temperature adjustment cavity on the left spiral stirring shaft 10 and flows into the second hot and cold circulation water box 18. Then, the hot water in the second hot and cold circulation water box 18 enters the temperature adjustment cavity on the right spiral stirring shaft 12, and finally circulates back into the first hot and cold circulation water box 17. Finally, the hot water is circulated back to the instant electric water heater 14 through the second hot water circulation pipe 143 and the hot water circulation pump 141 to achieve continuous hot water circulation heating. In this way, when the hot water passes through the hollow left spiral stirring shaft 10 and the right spiral stirring shaft 12, it can raise the temperature of the material in the fermentation tank 1. Similarly, when the temperature needs to be lowered, the air-cooled chiller 15 and the cold water circulation pump 151 can work, and with the cooperation of the first cold water circulation pipe 152 and the second cold water circulation pipe 153, the cold water refrigerated in the air-cooled chiller 15 can be introduced into the left spiral stirring shaft 10 and the right spiral stirring shaft 12 to lower the temperature of the material in the fermentation tank 1. This can assist in adjusting the material temperature and further optimize the fermentation temperature environment to ensure better fermentation effects.

[0039] As Figures 2-3 In addition, by setting up an annular conveyor belt type material turning mechanism, during fermentation, the second motor 5 can work to drive the first transmission wheel 501 to rotate. When the first transmission wheel 501 rotates, it drives the annular conveyor turning belt 502 and the second transmission wheel 503 to rotate. And since the turning plates 505 are evenly distributed on the annular conveyor turning belt 502, the material will be continuously lifted and dropped by the turning plates 505 as the annular conveyor turning belt 502 and the turning plates 505 rotate, thereby enabling continuous turning of the material. Moreover, the speeds of the annular conveyor turning belt 502 and the turning plates 505 can be adjusted according to the fermentation requirements to ensure more sufficient turning of the material during fermentation and better turning effects. Finally, the present invention can not only ensure continuous and uniform turning of the material, enabling rapid heat dissipation, but also design the spiral stirring shaft as a hollow structure and introduce hot water or cold water as needed to flexibly control the material temperature, which is beneficial to comprehensively optimizing the fermentation conditions, ensuring better fermentation effects of probiotic solids, and being suitable for popularization and application.
