Abstract
Description
Technical Field
[0001] This application relates to the field of food fermentation equipment technology, and in particular to a microbial fermentation device for processing beef jerky. Background Technology
[0002] In the processing of beef jerky, microbial fermentation is a crucial step in improving product quality. Through the fermentation action of probiotics, not only can the taste and flavor of beef jerky be improved, but it can also break down proteins and other components, increasing the product's nutritional value and digestibility. As the core equipment in this process, the performance of the microbial fermentation device directly affects the fermentation effect and the final quality of the beef jerky. Currently, there are many types of beef jerky fermentation devices on the market; however, in actual production, precise control of the fermentation process still faces many challenges, especially the maintenance of probiotic activity and uniform distribution in the fermentation environment, which has become a significant factor restricting fermentation efficiency and product quality.
[0003] Currently, most beef jerky fermentation on the market is regulated by fixed temperature parameters. However, a constant temperature cannot accurately match the peak activity requirements of probiotics during the logarithmic growth phase, resulting in limited bacterial proliferation efficiency and insufficient secretion of active substances. This directly leads to low probiotic activity. In addition, it not only prolongs the fermentation cycle to wait for the low-activity areas to complete the reaction, but also causes an imbalance in the generation of flavor substances due to different fermentation levels in different parts, ultimately resulting in an uncoordinated flavor in the beef jerky product. Utility Model Content
[0004] The purpose of this application is to provide a microbial fermentation device for beef jerky processing, which has the advantages of precisely controlling the temperature of the front, middle and rear sections of the material conveying pipe, matching the peak growth activity of probiotics, and improving the proliferation efficiency and activity of the microbial community, thus solving the problems mentioned in the background art.
[0005] This application provides a microbial fermentation device for beef jerky processing, employing the following technical solution: It includes a material conveying pipe, which is divided into three parts: a front section, a middle section, and a rear section. A feed pipe is fixedly installed on the outer side of the front section, and a discharge pipe is fixedly installed on the outer side of the rear section. Three sets of heating components are arranged on the outer side of the material conveying pipe, evenly distributed across the front, middle, and rear sections. Each heating component includes a heat-insulating shell fixedly connected to the outer side of the material conveying pipe, a heating tube arranged on the inner side of the heat-insulating shell, and a heater fixedly installed on the outer side of the heat-insulating shell. Three temperature sensors are fixedly installed on the outer side of the material conveying pipe. A rotating shaft is rotatably connected to the inner side of the material conveying pipe, and a spiral conveying blade is fixedly connected to the outer side of the rotating shaft. A drive motor is fixedly embedded on the outer side of the material conveying pipe, with the output end of the drive motor fixedly connected to one end of the rotating shaft. An atomizing spray assembly is arranged on the outer side of the middle section of the material conveying pipe.
[0006] By adopting the above technical solution and setting up the coordinated action between the heaters and heating tubes in the three sets of heating components, the front, middle and rear sections of the material conveying pipe can be heated in sections. At the same time, with the temperature monitoring of three temperature sensors, the temperature in each section can be precisely controlled to ensure that the temperature matches the peak activity of probiotics, improve the efficiency of bacterial proliferation and probiotic activity, avoid the imbalance of flavor substances, and achieve precise temperature control, uniform mixing of beef jerky materials and uniform distribution of bacterial liquid during the fermentation process, effectively improving fermentation efficiency and product flavor coordination.
[0007] Preferably, the side of the insulation shell closest to the material conveying pipe is open.
[0008] By adopting the above technical solution, the opening of the insulation shell allows the heat generated by the heating tube to be transferred more directly to the material conveying tube, reducing heat loss during the transfer process, improving heating efficiency, and ensuring that the temperature inside the material conveying tube can reach the required temperature quickly and accurately.
[0009] Preferably, the heating tube is arranged in a spiral shape, and the heating tube is wound around the outside of the material conveying pipe, with the heating tube and the outside of the material conveying pipe in close contact.
[0010] By adopting the above technical solution, the spiral shape of the heating tube increases the contact area between the heating tube and the material conveying tube, so that the heat can be evenly transferred to all parts of the material conveying tube, ensuring that the beef jerky material is heated evenly during the conveying process, which is conducive to the stable fermentation of the beef jerky material.
[0011] Preferably, the three temperature sensors are evenly distributed in the front, middle and rear sections of the material conveying pipe.
[0012] By adopting the above technical solution, the three temperature sensors are evenly distributed in the front, middle and rear sections of the material conveying pipe, which can monitor the temperature changes in different sections of the material conveying pipe in real time and accurately, providing precise data support for the temperature control of the heating component, and ensuring that the temperature of each section is always within the optimal range for probiotic growth.
[0013] Preferably, a protective shell is fixedly installed on the outside of the material conveying pipe, the outside of the feed pipe and the discharge pipe extend through the outside of the protective shell to the outside, the inside of the protective shell is filled with heat-insulating aerogel, the protective shell completely covers the three sets of heating components and the three temperature sensors, and a base is fixedly connected to the outside of the protective shell.
[0014] By adopting the above technical solution, the protective shell, together with the internal thermal insulation aerogel, can effectively reduce the heat loss inside the device and maintain a stable temperature environment. At the same time, the protective shell can protect the heating components and temperature sensors, extending their service life.
[0015] Preferably, the outer side of the spiral conveying blade has a plurality of evenly arranged perforations.
[0016] By adopting the above technical solution, the perforations opened on the outer side of the spiral conveyor blades allow the beef jerky to receive temperature evenly during the process of the spiral conveyor blades rotating and conveying the beef jerky material, so that it can have more sufficient contact with the bacterial liquid, heat, etc.
[0017] Preferably, the central dimension of the spiral conveying blade along the axial direction is smaller than the dimensions on both sides, and a plurality of circumferentially arrayed flip plates are fixedly connected to the inner side of the middle section of the material conveying pipe. The flip plates are inclined and adapted to the spiral conveying blade.
[0018] By adopting the above technical solution, when the above-mentioned spiral conveyor blades convey beef jerky material through the middle section, the flipping plate can flip the beef jerky material, so that the beef jerky material continuously changes position during the conveying process, further improving the mixing uniformity of beef jerky material and atomized bacterial liquid, and ensuring that the fermentation degree of each part of the beef jerky material is consistent.
[0019] Preferably, the atomizing spray assembly includes a diverter pipe and a bacterial liquid storage tank. The outer side of the bacterial liquid storage tank is fixedly connected to the outer side of the protective shell, and the outer side of the diverter pipe is fixedly connected to the inner side of the material conveying pipe. A plurality of equidistantly arranged atomizing nozzles are fixedly connected to the bottom surface of the diverter pipe.

The output end of the pump body is fixedly connected to a connecting pipe, and the end of the connecting pipe away from the output end of the pump body extends through the outer side of the protective shell to the inner side of the diverter pipe.
[0020] By adopting the above technical solution, through the coordinated action of the diversion pipe, bacterial liquid storage tank, pump body and atomizing nozzle, the pump body transports the bacterial liquid in the bacterial liquid storage tank to the diversion pipe through the connecting pipe, and then sprays it evenly onto the inside of the material conveying pipe through the atomizing nozzle, so that the bacterial liquid can come into uniform contact with the beef jerky material, ensuring that the probiotics are evenly distributed in the beef jerky material, laying a good foundation for the subsequent fermentation process.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This microbial fermentation device for beef jerky processing, by setting up three sets of heating components and evenly distributed temperature sensors, can precisely control the temperature of the front, middle and rear sections of the material conveying pipe, matching the peak growth activity of probiotics, improving the efficiency of bacterial proliferation and probiotic activity, and avoiding the imbalance of flavor substances. The open design of the heat-insulating shell and the spiral-wound heating tube improve heating efficiency and uniformity. At the same time, the protective shell and heat-insulating aerogel reduce heat loss and protect the internal components. In conjunction with the perforation of the spiral conveying blades and their cooperation with the flipping plate, it promotes the mixing of beef jerky materials.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5This application will be described in further detail below.
[0025] Example 1: A microbial fermentation device for beef jerky processing, please refer to... Figure 1 , Figure 2 and Figure 4 The system includes a material conveying pipe 1, which is divided into three sections: a front section, a middle section, and a rear section. A feed pipe 2 is fixedly installed on the outer side of the front section of the material conveying pipe 1, and a discharge pipe 3 is fixedly installed on the outer side of the rear section. Three sets of heating components 4 are evenly distributed across the front, middle, and rear sections of the material conveying pipe 1. The coordinated action of the heater 403 and the heating pipe 402 in these three sets of heating components 4 allows for zoned heating of the front, middle, and rear sections of the material conveying pipe 1. Each heating component 4 includes a heat-insulating shell 401 fixedly connected to the outer side of the material conveying pipe 1. A heating pipe 402 is installed inside the heat-insulating shell 401, and a heater 403 is fixedly installed on the outer side of the heat-insulating shell 401. Three temperature sensors 5 are fixedly installed on the outer side of the material conveying pipe 1. The temperature monitoring by these three temperature sensors 5 allows for precise temperature control within each section, ensuring that the temperature matches the peak activity of probiotic growth, improving bacterial proliferation efficiency and probiotic activity, and preventing flavor imbalance.
[0026] Please refer to Figure 2 and Figure 3 A rotating shaft 6 is rotatably connected to the inner side of the material conveying pipe 1, and a spiral conveying blade 7 is fixedly connected to the outer side of the rotating shaft 6. Multiple evenly arranged perforations 701 are opened on the outer side of the spiral conveying blade 7. These perforations 701 allow the beef jerky to receive temperature evenly during the rotation and conveying of the beef jerky by the spiral conveying blade 7, ensuring more thorough contact with the bacterial solution and heat. The central dimension of the spiral conveying blade 7 along the axial direction is smaller than the dimensions on both sides. Multiple circumferentially arrayed flipping plates 13 are fixedly connected to the inner side of the middle section of the material conveying pipe 1. The rotating plate 13 is inclined and is adapted to the spiral conveying blade 7. When the spiral conveying blade 7 conveys the beef jerky material through the middle section, the rotating plate 13 can flip the beef jerky material, so that the beef jerky material continuously changes position during the conveying process, further improving the mixing uniformity of the beef jerky material and the atomized bacterial liquid, and ensuring that the fermentation degree of each part of the beef jerky material is consistent. The outer side of the material conveying pipe 1 is fixedly embedded with a drive motor 8, and the output end of the drive motor 8 is fixedly connected to one end of the rotating shaft 6. The outer side of the middle section of the material conveying pipe 1 is provided with an atomizing spray assembly 9.
[0027] Example 2: A microbial fermentation device for beef jerky processing, please refer to... Figure 2 and Figure 4The heat insulation shell 401 has an opening on the side near the material conveying pipe 1. The opening of the heat insulation shell 401 allows the heat generated by the heating tube 402 to be transferred more directly to the material conveying pipe 1, reducing heat loss during the transfer process, improving heating efficiency, and ensuring that the temperature inside the material conveying pipe 1 can reach the required temperature quickly and accurately. The heating tube 402 is spirally arranged and wrapped around the outside of the material conveying pipe 1, with the heating tube 402 in close contact with the outside of the material conveying pipe 1. The spiral shape of the heating tube 402 increases the contact area between the heating tube 402 and the material conveying pipe 1, allowing heat to be evenly transferred to all parts of the material conveying pipe 1, ensuring that the beef jerky material is heated evenly during the conveying process, which is beneficial to the stable fermentation of the beef jerky material.
[0028] Please refer to Figure 1 and Figure 2 Three temperature sensors 5 are evenly distributed in the front, middle and rear sections of the material conveying pipe 1. These three temperature sensors 5 can monitor the temperature changes in different sections of the material conveying pipe 1 in real time and accurately, providing precise data support for the temperature control of the heating components 4, and ensuring that the temperature of each section is always within the optimal range for probiotic growth. A protective shell 11 is fixedly installed on the outside of the material conveying pipe 1. The outside of the inlet pipe 2 and outlet pipe 3 extends through the outside of the protective shell 11 to the outside. The inside of the protective shell 11 is filled with heat-insulating aerogel 10. The protective shell 11 completely covers the three sets of heating components 4 and the three temperature sensors 5. A base 12 is fixedly connected to the outside of the protective shell 11. The protective shell 11, together with the heat-insulating aerogel 10 inside, can effectively reduce the heat loss inside the device and maintain a stable temperature environment. At the same time, the protective shell 11 can protect the heating components 4 and the temperature sensors 5 and extend their service life.
[0029] Please refer to Figure 2 and Figure 5The atomizing spray assembly 9 includes a diversion pipe 901 and a bacterial liquid storage tank 903. The outer side of the bacterial liquid storage tank 903 is fixedly connected to the outer side of the protective shell 11. The outer side of the diversion pipe 901 is fixedly connected to the inner side of the material conveying pipe 1. A plurality of equidistantly arranged atomizing nozzles 902 are fixedly connected to the bottom surface of the diversion pipe 901. A pump body 904 is fixedly installed on the outer side of the bacterial liquid storage tank 903, and the input end of the pump body 904 extends through the outer side of the bacterial liquid storage tank 903 into the interior of the bacterial liquid storage tank 903. The output end of the pump body 904 is fixedly connected to a connecting pipe 905. One end of 905, away from the output end of the pump body 904, extends through the outer side of the protective shell 11 to the inner side of the diversion pipe 901. Through the coordinated action of the diversion pipe 901, the bacterial liquid storage tank 903, the pump body 904, and the atomizing nozzle 902, the pump body 904 transports the bacterial liquid in the bacterial liquid storage tank 903 to the diversion pipe 901 through the connecting pipe 905, and then evenly sprays it onto the inner side of the material conveying pipe 1 through the atomizing nozzle 902, so that the bacterial liquid can evenly contact the beef jerky material, ensuring that the probiotics are evenly distributed in the beef jerky material, laying a good foundation for the subsequent fermentation process.
[0030] It should be noted that the three temperature sensors 5 and the heaters 403 in the three sets of heating components 4 are all electrically connected to the external controller. At this time, the temperature sensors 5 can monitor the temperature of each segment in real time and feed the temperature back to the external controller to adjust the heating components 4 so that the temperature of each segment can accurately match the needs of different growth stages of probiotics.
[0031] The implementation principle of this application embodiment is as follows: When using the microbial fermentation device, the beef jerky material enters the front section of the material conveying pipe 1 from the feed pipe 2. At this time, the drive motor 8 drives the spiral conveying blades 7 on the rotating shaft 6 to rotate, conveying the beef jerky material forward along the material conveying pipe 1. Then, three sets of heating components 4 heat the front, middle and rear sections of the material conveying pipe 1 respectively. The heating tube 402 spirally winds and closely contacts the material conveying pipe 1 to ensure stable temperature transmission. Then, in conjunction with the heat insulation shell 401 and the heat-insulating aerogel 10 inside the protective shell 11, the temperature of each section is ensured to be stable and can be controlled independently. At the same time, the temperature sensor 5 can monitor the temperature of each section in real time and feed it back to the external controller to adjust the heating components 4, so that the temperature of each section is precisely matched to the needs of different growth stages of probiotics. Then, when the beef jerky material is conveyed to the middle section, the pump body 904 conveys the bacterial solution in the bacterial solution storage tank 903 to the diversion pipe 901. After that, it is atomized by the atomizing nozzle 902 and evenly sprayed onto the beef jerky material, promoting full contact between the probiotics and the beef jerky material. At the same time as the atomizing spray, the perforation 701 on the outer side of the spiral conveyor blade 7 and the flipping plate 13 in the middle section work together to flip the beef jerky material, so that the bacterial solution and the beef jerky material are evenly mixed and the beef jerky material is evenly heated. At the same time, the perforation 701 makes it easy for the beef jerky material to receive the temperature evenly. After that, the beef jerky material experiences a suitable temperature environment in the front, middle and rear sections, so that the probiotics can remain in an active state during the growth period. Finally, the fermented beef jerky material is discharged from the discharge pipe 3.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
