Description

High dissolved oxygen does not have agitator fermentation cylinder

Technical Field

The utility model relates to the technical field of biological fermentation, in particular to a high dissolved oxygen stirring-free fermentation tank.

Background

Mortierella alpina is a fungus producing arachidonic acid oil, and its mycelium is fine and its intact growth state is in the form of pomace. High dissolved oxygen level is needed in the growth process, but the method for increasing the dissolved oxygen level of the fermentation liquor is to start stirring and then increase ventilation. However, when stirring is started, shearing force is formed, the mycelium morphology is destroyed, and the yield is affected; increasing ventilation can also result in poor air availability and increased energy consumption.

Disclosure of Invention

The utility model aims to provide a high dissolved oxygen stirring-free fermentation tank, which has the function of safely and effectively improving the dissolved oxygen level of fermentation liquor.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a high dissolved oxygen does not have stirring fermentation cylinder, includes the jar body, the internal fixed n type pipeline that is provided with of jar, and the lower extreme mouth of pipe of n type pipeline is unsettled in the bottom top of the jar body, every n type pipeline is staggered from top to bottom, and evenly surrounds jar body center, be provided with gas distribution subassembly in the n type pipeline, gas distribution subassembly is including being fixed in the annular pipeline on the n type pipeline inner wall, connecting annular pipeline and leading out the external gas transmission pipeline of jar, annular pipeline is located n type pipeline one side intraductal, and the bottom evenly has offered a plurality of ventholes of ventilating.

Through adopting above-mentioned technical scheme, when the internal zymotic fluid of jar needs to increase dissolved oxygen level, the gas-supply pipe will let in sterile air in the annular duct to in the venthole from annular duct bottom, evenly arrange n type pipeline, simultaneously because n type pipeline is whole to soak in the zymotic fluid, the zymotic fluid in the n type pipeline will flow under the air current effect of venthole, and form the circulation flow of advancing from the one end mouth of pipe of n type pipeline, the mouth of pipe of the other end goes out, and the oxygen in the air current will fully even dissolve in the zymotic fluid of circulation flow, thereby quick promotion zymotic fluid in dissolved oxygen level.

The utility model is further provided with: the number of the n-type pipes is three, and the included angle between each n-type pipe is 60 degrees.

By adopting the technical scheme, the fermentation liquor circulation and dissolved oxygen effect are optimal.

The utility model is further provided with: one side pipe orifice of the n-type pipeline is lower than the other side pipe orifice of the n-type pipeline.

Through adopting above-mentioned technical scheme, not only can be better let the fermentation broth from top to bottom of jar body circulate flow in turn, but also can let the air of annular pipeline output stay longer in the fermentation broth, make the oxygen in the air have sufficient time to dissolve in the fermentation broth, improve the utilization ratio of air.

The utility model is further provided with: the inner side wall of the tank body is fixedly provided with a supporting frame for fixing the n-type pipeline.

Through adopting above-mentioned technical scheme, can be with n type pipeline stable fixation in the jar internal.

The beneficial effects of the utility model are as follows: through n type pipeline and gas distribution subassembly, not only make the zymotic fluid carry out the inner loop and flow, can also let the even abundant solution of oxygen in the sterile air moreover to when the dissolved oxygen level in safe promotion zymotic fluid, can also effectual improvement sterile air's utilization ratio.

Detailed Description

The technical scheme of the present utility model will be clearly and completely described in connection with specific embodiments. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

Examples: the utility model provides a high dissolved oxygen does not have agitator fermentation cylinder, as shown in fig. 1, fig. 2, including the jar body 1, the fixed three vertical n type pipeline 2 that are provided with in the jar body 1, and the lower extreme mouth of pipe of n type pipeline 2 is unsettled in the bottom top of jar body 1, every n type pipeline 2 is staggered from top to bottom arranged, and evenly around jar body 1 center, be provided with gas distribution subassembly in the n type pipeline 2, gas distribution subassembly is including being fixed in the annular pipeline 3 on the inner wall of n type pipeline 2, connect annular pipeline 3 and lead out the outer gas-supply pipe 4 ways of jar body 1, annular pipeline 3 is located n type pipeline 2 one side intraductal, and a plurality of ventholes 31 of ventilating have evenly been seted up to the bottom.

When the dissolved oxygen level of the fermentation liquid in the tank body 1 needs to be increased, sterile air is introduced into the annular pipeline 3 through the air delivery pipe 4, and is uniformly discharged into the n-type pipeline 2 through the air outlet holes 31 at the bottom of the annular pipeline 3, meanwhile, the fermentation liquid in the n-type pipeline 2 flows under the action of the air flow of the air outlet holes 31, and the circulating flow entering from the pipe orifice at one end and exiting from the pipe orifice at the other end of the n-type pipeline 2 is formed, and oxygen in the air flow is fully and uniformly dissolved in the circulating flowing fermentation liquid, so that the dissolved oxygen level in the fermentation liquid is rapidly improved. The pipe orifice on one side of the n-type pipeline 2, provided with the annular pipeline 3, is lower than the pipe orifice on the other side, so that fermentation liquid on the upper side and the lower side of the tank body 1 can flow alternately and circularly better, air output by the annular pipeline 3 stays in the fermentation liquid for a longer time, oxygen in the air is dissolved in the fermentation liquid for a sufficient time, and the utilization rate of the air is improved; the support frame 5 of fixed n type pipeline 2 is fixedly provided with to jar body 1 inside wall, can be with n type pipeline 2 stable fixed in jar body 1.
