Description

Technical Field

[0001] The invention belongs to the field of fermentation product devices, in particular to a meat product microbial fermentation device. Background Art

[0002] The meat powder fermentation process is a biotransformation technology based on microbial metabolic activities. It is widely used in fertilizer manufacturing and food production and processing. In the food processing industry, this process mixes meat powder raw materials with various auxiliary materials in a certain proportion and puts them into the fermentation tank, using the metabolic capacity of microorganisms to achieve deep conversion of the raw materials. During the fermentation process, microorganisms decompose macromolecules such as protein and fat in meat powder to generate small molecule amino acids, peptides, organic acids and flavor compounds, thereby giving the fermented products a unique flavor, rich nutritional value and excellent texture. This process can not only improve the utilization value of meat powder, but also produce food raw materials with specific functions and high quality to meet the modern food industry's demand for product diversity and nutritional value.

[0003] A patent document with publication number CN117025354B discloses a fermentation device for fermenting meat powder. The fermentation device includes a fermentation tank, a driving mechanism, a central pipe, an auxiliary material transport component, a boosting mechanism and a stirring component. An auxiliary material delivery port is provided at the top of the fermentation tank, a driving mechanism is installed at the bottom of the fermentation tank, the top of the driving mechanism is connected to the stirring component, and an annular cavity is provided on the side of the central pipe.

[0004] In the traditional meat meal fermentation process, meat meal raw materials and auxiliary materials are usually directly put into the fermentation tank for mixed fermentation. However, during the fermentation process, due to the metabolic activity of microorganisms and the dissolution and decomposition of the internal components of the meat meal, a large amount of fermentation permeate solution will be generated. This solution not only contains rich microbial flora, but also rich in various metabolites and nutrients. It is an important active ingredient in the fermentation process. However, due to the limitations of the structure and operation mode of the fermentation tank, these fermentation permeate solutions often accumulate in large quantities at the bottom of the tank, making it difficult to evenly spray or distribute them to the meat meal raw materials at different heights. This accumulation phenomenon leads to low fermentation efficiency and uneven fermentation effect of the meat meal raw materials during the fermentation process.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Figure 1-4 As shown, a meat product microbial fermentation device according to an embodiment of the present invention includes a fermentation tank body 1 and a feed inlet 12 fixedly installed above the fermentation tank body 1. The fermentation tank body 1 is covered with a top cover 13. A plurality of discharge cover plates 11 are movably installed below the fermentation tank body 1. The plurality of discharge cover plates 11 are used for discharging fermented products. A central transmission pipe 4 is installed at the center of the fermentation tank body 1. A plurality of stirring assemblies 2 are movably installed inside the fermentation tank body 1. The plurality of stirring assemblies 2 are distributed around the outside of the central transmission pipe 4. A plurality of driving components 3 are fixedly installed above the top cover 13. The number of driving components 3 corresponds to the number of stirring assemblies 2. The stirring assembly 2 includes a fixed member 21 fixedly mounted above the top cover 13 and an axial member 22 movably mounted below the fixed member 21 , and a plurality of blades 23 are fixedly mounted on the outer side of the axial member 22 ; The axial member 22 includes a fixed inner shaft 221 fixedly connected to the fixed member 21, and the outer movable sleeve of the fixed inner shaft 221 is provided with a rotating outer shaft 222. The driving member 3 is used to drive the rotating outer shaft 222 to rotate inside the fermentation tank body 1. The interior of the fixed inner shaft 221 is hollow, and a member for spraying the fermentation liquid is provided inside the bottom of the fixed inner shaft 221. The central transmission pipe 4 is used to collect the permeate that sinks to the bottom during the fermentation process inside the fermentation tank body 1 and transport the permeate to the fixed inner shaft 221.

[0025] Specifically, the meat powder raw materials and auxiliary materials are put into the interior of the fermentation tank body 1 through the feed port 12 for mixed fermentation. At this time, the multiple corresponding rotating outer shafts 222 inside the fermentation tank body 1 are driven to rotate by the drive of multiple driving components 3. At this time, the multiple fixed inner shafts 221 are fixed in position and do not rotate. The rotation of the rotating outer shaft 222 drives the multiple blades 23 to rotate to mix and stir the meat powder raw materials and auxiliary materials inside the fermentation tank body 1 to speed up the fermentation efficiency. In the process of mixing and stirring the two, due to the metabolic activity of microorganisms and the dissolution and decomposition of the internal components of the meat powder, a large amount of fermentation osmotic solution will be generated. This solution not only contains rich microbial flora, but also is rich in various metabolites and nutrients. It is an important active ingredient in the fermentation process. However, due to the setting of the fermentation tank body 1 and the action of gravity, a large amount of fermentation osmotic solution The liquid will be deposited at the inner bottom of the fermentation tank body 1, which will cause the meat powder at different heights inside the fermentation tank body 1 to be fermented unevenly. In this device, a central transmission pipe 4 is installed at the axial position of the fermentation tank body 1. The function of the central transmission pipe 4 is to suck up a large amount of fermentation permeate solution deposited at the inner bottom of the fermentation tank body 1 and transmit it to the interior of the fixed inner shaft 221. A structure for spraying is set at the inner bottom of the fixed inner shaft 221. This spraying structure can spray the meat powder raw material inside the fermentation tank body 1 through the rotating outer shaft 222. The spraying structure can be set at different heights of the fixed inner shaft 221, and then the meat powder raw materials and auxiliary materials at different heights can be mixed, sprayed, mixed and stirred inside the fermentation tank body 1 to avoid uneven fermentation. After fermentation, the meat powder is discharged through multiple discharge covers 11.

[0026] like Figure 3-4 As shown, the fixing member 21 includes a semicircular arc ring 212 fixedly installed above the top cover 13 and a fixing cover 211 fixedly installed above the semicircular arc ring 212 , and the top end of the fixed inner shaft 221 is fixedly connected to the lower axis position of the fixing cover 211 .

[0027] The driving component 3 includes a fixed motor 31 fixedly installed above the top cover 13. The fixed motor 31 is connected to a worm 32 through a shaft. One end of the worm 32 is movably connected to the semicircular ring 212. A turbine 33 is meshed and installed on the outer side of the worm 32. The turbine 33 is hollow inside and is mounted on the outer side of the top end of the rotating outer shaft 222.

[0028] The interior of the central transmission tube 4 is hollow, and an auxiliary material inlet 41 is opened at the top of the central transmission tube 4. A fixed connecting ring 42 is also fixedly installed on the top of the central transmission tube 4. A small suction pump 43 is fixedly installed inside the fixed connecting ring 42. A delivery pipe 44 is fixedly installed at the lower end of the small suction pump 43. The lower end of the delivery pipe 44 is at the bottom of the hollow interior of the central transmission tube 4. A plurality of connecting pipes 45 are fixedly installed above the small suction pump 43. One end of the plurality of connecting pipes 45 passes through the corresponding fixed cover 211 and extends to the interior of the fixed inner shaft 221.

[0029] Specifically, when it is necessary to rotate the outer shaft 222 to rotate and mobilize the blades 23 for mixing and stirring, the fixed motor 31 is used to drive the worm 32 to rotate, and the worm 32 is engaged with the turbine 33, so that the turbine 33 is driven to rotate, and the rotation of the turbine 33 drives the rotating outer shaft 222 and the multiple blades 23 provided on the rotating outer shaft 222 to rotate to perform stirring. At this time, the upper end of the fixed inner shaft 221 is fixedly connected to the fixed cover 211, so that the fixed inner shaft 221 is stationary. When a large amount of fermentation permeate solution inside the fermentation tank body 1 is deposited at the inner bottom of the fermentation tank body 1, it will be collected to the hollow bottom of the central transmission pipe 4 and driven by the small suction pump 43, so that a large amount of fermentation permeate solution at the hollow bottom of the central transmission pipe 4 is discharged from the delivery The tube 44 is transported to the interior of multiple connecting tubes 45, and then transported from the connecting tube 45 to the corresponding fixed inner shaft 221, and the supply spraying structure is operated. When the meat powder raw material and auxiliary material are fermented inside the fermentation tank body 1, it is usually necessary to continue to add a small amount of auxiliary material into the fermentation tank body 1 for secondary mixing. However, if the auxiliary material is added from the feed port 12 at this time, it can only act on the top position inside the fermentation tank body 1 in large quantities, which is not conducive to speeding up the fermentation rate. In this device, a small amount of auxiliary material required for subsequent work can be added through the auxiliary material inlet 41, and the auxiliary material is mixed with the fermentation permeate solution at the bottom of the central transmission tube 4, and then sprayed into the meat powder raw material at different heights through the spraying structure. At this time, stirring and fermentation are carried out, which can significantly improve the fermentation efficiency.

[0030] like Figure 5 As shown, a bottom plate 14 is fixedly installed on the inner bottom of the fermentation tank body 1, and a plurality of through grooves 141 are opened inside the bottom plate 14. A fixed outer ring 5 is fixedly installed on the bottom of the fermentation tank body 1, and a lifting block 52 is lifted and lowered inside the fixed outer ring 5. A plurality of lifting columns 521 are fixedly installed above the lifting block 52. The plurality of lifting columns 521 are located directly below the corresponding through grooves 141, and a through groove 2 522 is opened between two adjacent lifting columns 521.

[0031] A fixed inner ring 51 is fixedly mounted on the inner bottom of the fixed outer ring 5 , and a plurality of telescopic columns 511 are fixedly mounted above the fixed inner ring 51 . The upper ends of the plurality of telescopic columns 511 are fixedly connected to the lower side of the lifting block 52 .

[0032] A conical shell 6 is fixedly installed below the fixed outer ring 5. The interior of the conical shell 6 is hollow. The central transmission pipe 4 passes through the bottom plate 14, the lifting block 52 and the conical shell 6 and extends downward. A filter ring net 46 is fixedly installed in the bottom of the central transmission pipe 4. The filter ring net 46 is located at the bottom position within the axis of the conical shell 6.

[0033] Specifically, when stirring and fermenting is carried out inside the fermentation tank body 1, the multiple telescopic columns 511 are in an extended state. At this time, the multiple lifting columns 521 are inserted into the corresponding through-groove 141, and the top of the lifting column 521 is at the same horizontal height as the top of the through-groove 141, which does not affect the stirring and fermentation of the meat powder raw materials and auxiliary materials inside the fermentation tank body 1. After a period of fermentation, a large amount of fermentation osmotic solution will be generated due to the metabolic activity of microorganisms and the dissolution and decomposition of the internal components of the meat powder. A large amount of fermentation osmotic solution is deposited on the top of the bottom plate 14 under the action of gravity. At this time, the multiple telescopic columns 511 are contracted, so that the lifting block 52 descends, that is, the lifting column 521 descends and disengages from the through-groove 141 until the top of the lifting column 521 There is a certain distance from the bottom plate 14. At this time, the fermentation permeate solution deposited on the bottom plate 14 falls into the interior of the conical shell 6 through the through groove 1 141 and the through groove 2 522 opened on the lifting block 52. A conical space is opened inside the conical shell 6, so a large amount of fermentation permeate solution accumulates at the bottom of the conical shell 6 and enters the hollow bottom of the central transmission pipe 4 through the filter ring network 46. That is, the central transmission pipe 4 collects the fermentation permeate solution accumulated at the bottom of the fermentation tank body 1 at this time, and then transports the fermentation permeate solution to the fixed inner shaft 221 under the suction work of the small suction pump 43. Through the setting of this device, the fermentation permeate solution that has settled to the bottom can be quickly collected to avoid uneven fermentation caused by its settling to the bottom.

[0034] like Figure 6-7 As shown, an inner ring groove 2211 is opened inside the fixed inner shaft 221, and a bearing 2212 is installed inside the inner ring groove 2211. The inner ring of the bearing 2212 is fixedly connected to the inner wall of the inner ring groove 2211, and the outer ring of the bearing 2212 is fixedly connected to the inner wall of the rotating outer shaft 222.

[0035] Specifically, through the setting of the bearing 2212, when the rotating outer shaft 222 rotates, the outer ring of the bearing 2212 rotates along with it, while the fixed inner shaft 221 remains stationary. The setting of the bearing 2212 makes the rotation of the rotating outer shaft 222 smoother.

[0036] Example 2: Figure 7-8 As shown, compared with Example 1, another embodiment of the present invention is: a component annular groove 2221 is opened inside the rotating outer shaft 222, a plurality of support columns 2222 are fixedly installed inside the component annular groove 2221, a plurality of micro-spray heads 2213 are fixedly installed inside the fixed inner shaft 221, one end of the plurality of micro-spray heads 2213 is connected to the hollow position inside the fixed inner shaft 221, and the plurality of micro-spray heads 2213 are located inside the corresponding component annular groove 2221.

[0037] A plurality of paddle columns 1 231 are fixedly installed inside the blade 23 , a paddle column 232 is fixedly installed inside the blade 23 close to the rotating outer shaft 222 , and a U-shaped column 233 is fixedly installed in the middle of the paddle column 232 , and the U-shaped column 233 is inside the component annular groove 2221 .

[0038] Specifically, the interior of the fixed inner shaft 221 is hollow. When one end of the connecting pipe 45 passes through the fixed cover 211 to transport the fermentation osmotic solution settled at the bottom of the fermentation tank body 1 to the interior of the fixed inner shaft 221, it will enter the hollow interior of the fixed inner shaft 221 until the hollow interior of the fixed inner shaft 221 is full of accumulation. At this time, multiple micro-spraying heads 2213 will spray out the fermentation osmotic solution to mix it into the meat powder raw materials and auxiliary materials outside the rotating outer shaft 222. When a small amount of auxiliary materials that need to be mixed later is put into the auxiliary material inlet 41, that is, at this time, the fermentation osmotic solution at the inner bottom of the central transmission pipe 4 is mixed with a small amount of auxiliary materials, and what is sprayed out by the multiple micro-spraying heads 2213 is a mixed liquid of the fermentation osmotic solution and the auxiliary materials. The micro-spraying heads 221 set at different heights 3 The sprayed solution can act on the meat powder and auxiliary materials at different heights to prevent the meat powder and auxiliary materials at different heights from being fermented unevenly. During the spraying process of the micro-spray head 2213, the fixed inner shaft 221 is fixed, while the rotating outer shaft 222, the paddle 23, the paddle column 1 231, the paddle column 232 and the U-shaped column 233 rotate. At this time, the U-shaped column 233 is close to the outside of the micro-spray head 2213 and is inside the component ring groove 2221. During the spraying process of the micro-spray head 2213, the rotation setting of the paddle column 232 and the U-shaped column 233 can push the meat powder raw materials and auxiliary materials outside the micro-spray head 2213 to move outward, and scratch the meat powder raw materials and auxiliary materials outside the micro-spray head 2213, so as to prevent the spraying area of ​​the micro-spray head 2213 from becoming smaller.

[0039] Working principle: meat powder raw materials and auxiliary materials are put into the interior of the fermentation tank body 1 through the feed port 12 for mixed fermentation. At this time, driven by multiple driving components 3, multiple corresponding rotating outer shafts 222 inside the fermentation tank body 1 are driven to rotate. At this time, multiple fixed inner shafts 221 are fixed in position and do not rotate. The rotation of the rotating outer shaft 222 drives multiple blades 23 to rotate and mix the meat powder raw materials and auxiliary materials inside the fermentation tank body 1 to speed up the fermentation efficiency. In the process of mixing and stirring the two, due to the metabolic activity of microorganisms and the dissolution and decomposition of the internal components of the meat powder, a large amount of fermentation permeate solution will be generated. This solution not only contains rich microbial flora, but also is rich in various metabolites and nutrients. It is fermentation The fermentation tank body 1 is an important active ingredient in the fermentation process. However, due to the setting of the fermentation tank body 1 and the action of gravity, a large amount of fermentation permeate solution will be deposited at the inner bottom position of the fermentation tank body 1, which will cause the meat powder at different heights inside the fermentation tank body 1 to be fermented unevenly. In this device, a central transmission pipe 4 is installed at the axial position of the fermentation tank body 1. The function of the central transmission pipe 4 is to suck up a large amount of fermentation permeate solution deposited at the bottom of the fermentation tank body 1 and transfer it to the interior of the fixed inner shaft 221. A spraying structure is set at the inner bottom of the fixed inner shaft 221. This spraying structure can spray the meat powder raw material inside the fermentation tank body 1 through the rotating outer shaft 222. The spraying structure can be set at different height positions of the fixed inner shaft 221. Furthermore, the meat powder raw materials and auxiliary materials at different heights can be mixed, sprayed, and stirred inside the fermentation tank body 1 to avoid uneven fermentation. After fermentation, the meat powder is discharged through multiple discharge covers 11. The internal hollow structure of the fixed inner shaft 221 is fixed. When one end of the connecting pipe 45 passes through the fixed cover 211 to transport the fermentation osmotic solution that has sunk to the bottom of the fermentation tank body 1 to the fixed inner shaft 221, it will enter the hollow interior of the fixed inner shaft 221 until the hollow interior of the fixed inner shaft 221 is filled. At this time, multiple micro-spray heads 2213 will spray out the fermentation osmotic solution to mix it into the meat powder raw materials and auxiliary materials outside the rotating outer shaft 222. When a small amount of auxiliary materials that need to be mixed later are put into the auxiliary material inlet 41 At this time, the fermentation osmotic solution at the inner bottom of the central transmission tube 4 is mixed with a small amount of auxiliary materials, and the multiple micro-spraying heads 2213 spray out a mixed liquid of the fermentation osmotic solution and the auxiliary materials. The solutions sprayed by the micro-spraying heads 2213 set at different heights can act on the meat powder and auxiliary materials at different heights to avoid uneven fermentation of the meat powder and auxiliary materials at different heights. During the spraying process of the micro-spraying heads 2213, the fixed inner shaft 221 is fixed, while the rotating outer shaft 222, the paddle 23, the paddle column 1 231, the paddle column 232 and the U-shaped column 233 rotate. At this time, the U-shaped column 233 is close to the outer side of the micro-spraying head 2213 and is inside the component annular groove 2221. During the spraying process of the micro-spraying heads 2213,The rotation of the paddle column 232 and the U-shaped column 233 can push the meat powder raw materials and auxiliary materials outside the micro-spraying head 2213 to move outward, and scrape the meat powder raw materials and auxiliary materials outside the micro-spraying head 2213, thereby preventing the spraying area of ​​the micro-spraying head 2213 from being reduced.
