[0002] Postbiotics refer to preparations of inanimate microorganisms and / or their components that are beneficial to the health of the host, including inactivated complete bacterial cells, bacterial cell wall components, extracellular polysaccharides and / or their metabolites. Postbiotics have high heat resistance, storage resistance, acid and alkali resistance, good safety, long shelf life, and are more suitable for various high-temperature and high-pressure processing environments. They have a wide range of applications. Solid-state fermentation postbiotics retain the beneficial metabolites of microorganisms to the greatest extent, have a high concentration of effective substances, and are richer in metabolites, and have unique effects and advantages in applications;

[0003] Continuous sterilization equipment is a sterilization device widely used in many industries such as food and pharmaceuticals. It can effectively sterilize materials in a continuous production process. Compared with intermittent sterilization equipment, it greatly improves production efficiency. It can process a large amount of materials, and the sterilization time is relatively fixed, which can better adapt to the rhythm of large-scale industrial production.

[0004] Continuous sterilization equipment belongs to the continuous sterilization system of solid-state fermentation medium. The solid-state fermentation medium system is a technical system that uses solid-state medium for microbial fermentation. Solid-state fermentation is a process of culturing microorganisms on a wet solid matrix with no or almost no free water. In the process of producing and preparing solid-state fermentation postbiotics, sterilization equipment is required to perform high-temperature and high-pressure sterilization and maturation treatments on the components of the medium.

[0005] At present, when using continuous sterilization equipment, when continuously sterilizing the postbiotic culture medium, a rotary cooking pot is usually used to sterilize the components of the culture medium at high temperature and high pressure, and then cooling, inoculation, packaging and other multiple processing steps are carried out. Not only are there many steps and a long processing cycle, but also the energy consumption is high, the sterilization efficiency is low, and it is easy to cause contamination by miscellaneous bacteria during inoculation, and it is difficult to achieve high efficiency and environmental protection effects. Therefore, a solid-state fermentation postbiotic culture medium sterilization equipment and a method of use thereof are proposed, so that the culture medium mixing, sterilization, cooling and inoculation, packaging design can be combined, and the culture medium mixing sterilization, cooling inoculation and packaging processing steps can be realized simultaneously, which can not only simplify the traditional multiple processing steps and use them more efficiently and reliably, but also the steam heat energy generated by high-temperature sterilization can be recycled and reused, reducing resource waste, and is also conducive to further improving sterilization efficiency and reducing energy consumption.

[0051] For example, Figure 1-7 As shown, the present invention also includes step 1: medium loading: first, various components of the solid-state fermentation postbiotic medium are added to the loading trough 6 of the pretreatment box 3 through the first feeding port 301 and the second feeding port 302 respectively through the external conveyor belt, and the medium components fall into the receiving trough 603 of the receiving rack 602 through the first feeding port 301 and the second feeding port 302 in sequence, and a preliminary medium mixing treatment is performed, and at the same time, the chain conveyor 601 drives the receiving rack 602 to perform a flip feeding action, so that the postbiotic medium after the preliminary mixing enters the high-temperature sterilization tank 7;

[0052] Step 2: Mixing of culture medium and high temperature sterilization treatment; the culture medium entering the high temperature sterilization tank 7 is driven by the driving motor 707, and follows the rotating rod 701 and the spiral blade 702 to flip, mix, and move to one side of the discharge port, and at the same time, the steam generator 4 is turned on to transport steam to the culture medium in the high temperature sterilization tank 7 through the steam pipe 703 and the steam nozzle 704 to perform high temperature sterilization treatment simultaneously;

[0056] When the present invention is used, firstly, various components of the solid-state fermentation postbiotic culture medium are added to the loading trough 6 of the pretreatment box 3 through the first loading port 301 and the second loading port 302 respectively through the external conveyor belt, and the culture medium components fall into the receiving trough 603 of the receiving rack 602 through the first loading port 301 and the second loading port 302 in sequence, and a preliminary culture medium mixing treatment is performed. At the same time, the chain conveyor 601 is manually opened, and the receiving rack 602 is driven by the chain conveyor 601 to perform a flipping and loading action, so that the postbiotic culture medium after the preliminary mixing enters the high-temperature sterilization tank 7;

[0057] Then, the culture medium enters the high-temperature sterilization tank 7, and under the drive of the driving motor 707, follows the rotating rod 701 and the spiral blade 702 to flip, mix, and move to one side of the discharge port, thereby realizing the mixing treatment of the culture medium. At the same time, the steam generator 4 is turned on, and steam is transported to the culture medium in the high-temperature sterilization tank 7 through the steam pipe 703 and the steam nozzle 704 to perform high-temperature sterilization treatment simultaneously. At the same time, the steam after the high-temperature sterilization treatment is recovered to the steam recovery tank 8 through the steam collection pipe 802, and is sent to the culture medium in the receiving rack 602 through the air outlet 801.

[0058] Then, after completing the high-temperature sterilization, the culture medium enters the cooling inoculation tank 201 of the cooling inoculation box 2, and the external pumping coolant passes through the spiral guide groove 202 of the cooling jacket 202 to take out the heat in the culture medium after the high-temperature sterilization, and quickly dissipate the heat. At the same time, the motor 207 drives the screw rod 205 to rotate, and the ball slider 206 drives the sliding sleeve 901 to reciprocate horizontally. The stirring seat 902, the stirring blade 903 and the micro motor 904 are used to stir the material to increase the cooling speed. When the temperature sensor shows that the value reaches the expected value, it is then passed through the inoculation storage box 2 09 and inoculation nozzle 208, by pumping the culture medium into the cooling inoculation tank 201 for inoculation processing, the displacement and flipping of the turning component 9 are used again to improve the uniformity of the culture medium inoculation, and the condensate collection port, filter plate 705, reflux water tank 706, condensate water tank 607 and guide cover 606 of the cooling inoculation tank 201 can collect the condensate generated during the sterilization of the culture medium into the water storage tank 608, and the condensate recovered in the water storage tank 608 is pumped into the steam generator 4, which can further reduce the waste of resources and make the use more energy-saving and efficient;

[0059] Finally, after the cooling and inoculation treatment is completed, the control valve of the cooling and inoculation tank 201 feed port is manually opened to allow the postbiotic culture medium after cooling and inoculation to enter the filling machine 5, and then the culture medium is packaged and processed by the filling machine 5. The overall structure is simple and the use is more flexible and efficient. By simultaneously realizing the culture medium mixing sterilization, cooling and inoculation and packaging processing steps, it can not only simplify the traditional multi-step processing steps, but also recover the steam heat energy generated by high-temperature sterilization for reuse, reduce resource waste, and help further improve sterilization efficiency and reduce equipment energy consumption.
