[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] In this embodiment, front, back, left, right, up and down are represented by Figure 1 Describes the datum. Figures 1-6 , the utility model provides a technical solution:

[0024] A high-yield probiotic fermentation device for protease comprises a stirring barrel 1, in which an active stirring rod 2 and two driven stirring rods 3 are rotatably mounted, a linkage mechanism being provided between the active stirring rod 2 and the driven stirring rod 3, a stirring motor 21 being fixedly mounted on the upper surface of the stirring barrel 1, an output end of the stirring motor 21 being fixedly connected to the top end of the active stirring rod 2, a ventilation cavity being provided on the upper surface of each of the driven stirring rods 3, and a plurality of one-way exhaust valves 31 connected to the ventilation cavity being fixedly mounted at equal intervals on the outer surface of each of the driven stirring rods 3, a pipeline rotary joint body 4 being fixedly mounted on the top end of each of the two driven stirring rods 3, and a fixing frame 41 being fixedly mounted between the pipeline rotary joint body 4 and the stirring barrel 1;

[0025] A heat shield 11 is fixedly mounted on the outer surface of the mixing barrel 1. A mounting cavity 12 is formed between the heat shield 11 and the mixing barrel 1. An air inlet 121 is provided on the left side of the mounting cavity 12. A constant temperature electric heating pipe 13 is coiled inside the mounting cavity 12. An air supply device 5 is installed between the mounting cavity 12 and the air inlet end of the pipeline rotary joint body 4. A circulation pipe 14 is installed between the mounting cavity 12 and the inner cavity of the mixing barrel 1.

[0026] Combine Figure 1 and Figure 2 As shown, after starting the air supply device 5, external air can be drawn into the installation cavity 12 from the air inlet end, and then after being heated by the constant temperature electric heating tube 13, the air is supplied to the two driven stirring rods 3 respectively through the pipeline rotary joint body 4 by the air supply device 5. As the driven stirring rod 3 stirs, the air is discharged into the stirring barrel 1 through the one-way exhaust valve 31 at different heights above and below, and the probiotics are evenly supplied with oxygen and heat, thereby achieving uniform oxygen supply, ensuring the consistent growth rate of the probiotics, thereby ensuring the fermentation quality, and improving the efficiency of probiotic fermentation.

[0027] It should be noted that if Figure 3 As shown, the linkage mechanism includes two driven gears 32 and a driving gear 22. The two driven gears 32 are respectively sleeved on the outer surface of the upper end of the corresponding driven stirring rod 3, and the driving gear 22 is sleeved on the outer surface of the upper end of the active stirring rod 2, and the driving gear 22 is meshed with the driven gear 32. When the stirring motor 21 drives the active stirring rod 2 to rotate, the driven stirring rods 3 on both sides can respectively drive the two driven stirring rods 3 to rotate under the linkage of the driving gear 22 and the driven gear 32, thereby realizing the movement of the three stirring rods to stir and mix the probiotics of the protease in the stirring barrel 1, so as to achieve the purpose of promoting the fermentation reaction of the probiotics and improving the fermentation efficiency and quality.

[0028] Combine Figure 1 and Figure 2As shown, the air supply device 5 includes an air pump 51, the air inlet end of the air pump 51 is connected to the installation cavity 12 (the connection here can be through an external air pipe, or the air inlet and exhaust ends of the two can be directly connected by threaded connection or other methods, as long as it can ensure that the air pump 51 can extract the gas in the installation cavity 12 and supply it to the air pipe 52), and the exhaust end of the air pump 51 is connected to the air pipe 52, and the end of the air pipe 52 away from the air pump 51 is connected to a three-way pipe 53, and the two exhaust ends of the three-way pipe 53 are respectively connected to the pipeline The air inlet ends of the rotary joint body 4 are connected. After the air supply device 5 is started, the gas in the installation cavity 12 can be supplied to the two pipeline rotary joint bodies 4 through the air pipe 52 and the three-way pipe 53, and finally poured into the ventilation cavity of the driven stirring rod 3 and discharged from the one-way exhaust valve 31. In this way, uniform oxygen and heat supply in the stirring barrel 1 is achieved, creating suitable environmental conditions for the probiotic fermentation process in the stirring barrel 1, which helps to improve the efficiency and quality of probiotic fermentation and ensure the stability and reliability of the fermentation process.

[0029] In order to avoid the entry of dust particles into the process of oxygen supply to probiotic fermentation, Figure 2 As shown, a filter cover 122 is screwed and installed at the air inlet 121.

[0030] like Figure 2 As shown, a discharge pipe 15 with a valve is fixedly installed on the lower surface of the mixing barrel 1. After fermentation, the discharge pipe 15 with a valve can be opened to discharge the fermented material from the mixing barrel 1.

[0031] like Figure 2 As shown, a feed pipe 16 with a sealing cap screwed on the top is fixedly installed on the upper surface of the mixing barrel 1. After unscrewing the sealing cap, fermentation raw materials and reaction materials can be added into the mixing barrel 1 through the feed pipe 16.

[0032] Finally, in order to prevent the raw materials from splashing onto the gears during the fermentation and stirring process, thereby causing adverse effects on the transmission effect, such as Figure 2 As shown, a partition 6 is fixedly installed in the mixing barrel 1, and the active stirring rod 2 and the driven stirring rod 3 both pass through the partition 6. The driving gear 22 and the driven gear 32 are both arranged above the partition 6. This can isolate the gears from the stirring area to avoid contact between the two, thereby ensuring the transmission effect of the gears, maintaining the stable operation and efficient transmission of the fermentation device during the stirring process, and providing reliable power support for probiotic fermentation.
