Description

Technical Field

[0001] The present application relates to microbial fermentation technology, and in particular to a microbial mixed fermentation device. Background Art

[0002] The culture medium is used to create suitable fermentation conditions for microorganisms in the fermentation tank, so that the microorganisms can ferment in the fermentation device. The fermentation conditions of microorganisms require not only sufficient nutrients and appropriate acid-base conditions, but also a stable ambient temperature.

[0003] However, heat is usually released during the fermentation process of microorganisms, and if it is not controlled and adjusted in time, the fermentation efficiency and effect will be affected. Therefore, it is necessary to continuously adjust the ambient temperature in the tank during the fermentation process of microorganisms.

[0004] In the existing fermentation device, circulating water is poured into the jacket outside the tank body, and the ambient temperature inside the tank body is adjusted by heat exchange between the circulating water and the tank body. Although it has a certain control effect, the heat exchange between the jacket and the side wall of the tank body is inefficient and slow, and the temperature of the culture environment inside the tank body cannot be adjusted in time. In addition, due to the low efficiency of heat conduction of the culture medium, only heat exchange of the side wall of the tank body cannot timely adjust the temperature of the center of the culture medium in the tank body. Utility Model Content

[0007] Optionally, a vacuum jacket is fixedly mounted on the outer wall of the fermentation barrel.

[0008] Optionally, a floating plate capable of sliding up and down is horizontally provided in the fermentation barrel, a plurality of exhaust holes are provided on the floating plate, a one-way valve for exhausting air upwards is installed in the exhaust holes, and an exhaust pipe is provided on the cover body.

[0011] Compared with the prior art, the beneficial effects of the microbial mixed fermentation device provided in this application are:

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0021] like Figure 1-Figure 4 As shown, an embodiment of the present application provides a microbial mixed fermentation device, including a fermentation barrel 1, wherein a cover body 3 is provided on the top of the fermentation barrel 1, and a discharge pipe 4 is provided on the bottom thereof. An agitator 6 and a temperature monitoring device 13 are installed in the fermentation barrel 1, and an air distribution plate 7 is installed on the bottom wall of the fermentation barrel 1. A plurality of air outlet holes 8 are evenly distributed on the top surface of the air distribution plate 7. The air distribution plate 7 is connected to an external oxygen production device through a connecting pipe 10. The connecting pipe 10 is arranged to pass through a temperature control box 9 and is folded and distributed inside the temperature control box 9. Circulating water is injected into the temperature control box 9 through the inlet and outlet pipes.

[0022] When in use, the microorganisms are mixed with the culture medium and then injected into the fermentation barrel 1, the cover body 3 is closed to seal the microorganisms for fermentation, and the microorganisms are stirred regularly by the stirrer 6 to make them evenly distributed and conducive to fermentation. During the fermentation process, the oxygen production equipment supplements oxygen into the fermentation barrel 1 through the air outlet 8 through the connecting pipe 10, and the oxygen can be evenly dispersed into the fermentation barrel 1 through the air distribution plate 7. According to the requirements of the fermentation conditions, circulating water for temperature control is injected into the temperature control box 9 through the inlet and outlet pipes on the temperature control box 9, and the circulating water contacts the outer wall of the connecting pipe 10 for heat exchange. When oxygen passes through the connecting pipe 10 in the temperature control box 9, the oxygen in the connecting pipe 10 is heated or cooled by the temperature control box 9, and the fermentation temperature in the fermentation barrel 1 is quickly adjusted by controlling the temperature of the oxygen entering the fermentation barrel 1.

[0023] In this embodiment, during the fermentation and cultivation of the microorganisms in the fermentation barrel 1 through the culture medium, oxygen is produced by the oxygen production equipment, and then the oxygen is supplemented to the fermentation barrel 1 from the air outlet 8 through the connecting pipe 10. According to the requirements of the fermentation conditions, the temperature of the oxygen entering the fermentation barrel 1 is adjusted by controlling the temperature of the circulating water in the temperature regulating box 9. The oxygen entering the fermentation barrel 1 has the advantages of wide distribution and sufficient contact. After rapid diffusion, it can quickly exchange heat with the culture medium in the fermentation barrel 1, and quickly adjust the ambient temperature in the fermentation barrel 1.

[0024] In a possible implementation, a vacuum jacket 2 is fixedly mounted on the outer wall of the fermentation barrel 1 .

[0025] The vacuum jacket 2 can play a role of heat insulation, reduce the influence of the external room temperature on the fermentation temperature in the fermentation barrel 1, and reduce the fluctuation of the fermentation temperature.

[0026] In a possible implementation, a floating plate 11 capable of sliding up and down is horizontally disposed in the fermentation barrel 1 , a plurality of exhaust holes 12 are disposed on the floating plate 11 , a one-way valve for exhausting air upwards is installed in the exhaust hole 12 , and an exhaust pipe 5 is disposed on the cover body 3 .

[0027] During fermentation, the floating plate 11 floats on the liquid surface of the culture medium. The excess oxygen and waste gas discharged upward rise to the liquid surface and are discharged through the exhaust holes 12 on the floating plate 11, so that the waste gas is separated from the culture medium. The excess oxygen and waste gas at the upper end of the fermentation barrel 1 are pumped out through the exhaust pipe 5.

[0028] In a possible implementation, the temperature monitoring device 13 is installed on the floating board 11 , and a sensor thereof passes through the center of the floating board 11 vertically downward.

[0029] The temperature monitoring device 13 installed at the center of the floating plate 11 can more accurately measure the temperature at the center of the culture medium and improve the accuracy of the regulation.

[0030] In a possible implementation, a plurality of limiting blocks 14 distributed in a ring shape are fixed on the inner wall of the fermentation barrel 1 , and the limiting blocks 14 are arranged below the floating plate 11 .

[0031] The limiting block 14 disposed below the floating plate 11 can limit the floating plate 11 and prevent the floating plate 11 from pressing on the agitator 6 when the liquid level of the discharged culture medium drops.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
