Technical field
A kind of biological fermentation device is the utility model is related to, more particularly to the defoaming in a kind of high-density biology fermentation tank
Device.
Background technology
Fermentation Engineering is to refer to the process for being manufactured or being produced some products using microorganism, and fermentation technique is that the mankind more early slap
One of production technology held.At present, substantial amounts of industrial process still needs the application of fermentation technique.In fermentation technique, fermentation tank
It is a kind of common equipment, fermentation tank is typically all the larger tank body of volume, and bubble, such as wine can be produced in actual production process
Fermentation tank in smart production process.Caused foam is the scattered dispersion in a liquid of a large amount of gases in fermentation process, its
Dispersed phase is gas, and continuous phase is zymotic fluid.
Particularly during high density fermentation produces, because yeast density is high in fermentation tank, this can compare common fermentation
Process produces more bubbles, and with a large amount of generations of bubble, tank inner volume is occupied by foam, the actually available capacity of fermentation tank
Reduce, make the volumetric efficiency of fermentation tank reduce.
A large amount of presence of foam can take strain out of, cause imbalance and the waste of strain of fermentation process.Fermentation process
Constantly stirring and ventilation so that bubble constantly rises, and causes " race liquid " phenomenon, and taking out of for liquid will increase later separation mistake
Journey is born.If a large amount of bubbles caused by fermentation process without any processing, are caused miscellaneous bacteria to be infected, product can be caused to send out
The failure of ferment process.
Currently used two kinds of debubbling methods：Waited first, stopping stirring after inlet and outlet valve is closed when foam is excessive
The disappearance of bubble, inlet and outlet valve and agitating device are reopened again after lather collapse.Another kind is to add to have gone out in fermentation tank
The defoamer of bacterium.Although two kinds of conventional debubbling methods can reach the purpose of defoaming, delay production cycle and suppression can be produced
The problem of growth processed.
Utility model content

Face and it is enclosed on outside corrugated plating group, overhead gage is located at the surface of corrugated plating group.
As a preferred embodiment, the quantity of silk screen is two, the symmetrical inwall installed in fermentation tank, and be close to send out
The inwall of fermentation tank body；Gap is between two silk screens and positioned at the position of center ofthe in fermentation tank.
As a preferred embodiment, silk screen is semicircle, and the inclined downward out of outside upper direction, 5~10 ° of angled downward from horizontal.
As a preferred embodiment, orifice plate is circular slab, the periphery of equal orifice plate is more than conical baffled lower end；On equal orifice plate
The cellular through hole run through up and down of cloth.
As a preferred embodiment, the upper and lower end face of orifice plate is uneven.
As a preferred embodiment, conical baffled upper end open is less than lower ending opening, upper end open is trapped among the outer of corrugated plating group
Wall, lower ending opening are close to the upper surface of equal orifice plate.
As a preferred embodiment, corrugated plating group is pressed into by polylith corrugated plating, it is provided with above and below undulatory and runs through between corrugated plating
Passage.
As a preferred embodiment, corrugated plating is bent at least provided with three.
As a preferred embodiment, corrugated plating group is cylinder, overhead gage is circular wave plate, overhead gage and corrugated plating group perpendicular
The upward projected area of Nogata is equal.
As a preferred embodiment, spray head is provided between corrugated plating group and overhead gage.
Principle of the present utility model is：By the method physical defoaming of multilayer barrier, a large amount of bubbles are captured by silk screen first,
Eliminate part bubble, with being on the increase for bubble, bubble is uniformly distributed by equal orifice plate, residual bubble through conical baffled capture,
Eliminated through corrugated plating group and overhead gage, overhead gage stops the bubble that the upper gas outlet of corrugated plating group is emerged, significant to reduce
The presence of bubble.
Generally speaking, the utility model has the following advantages that：
1) defoaming effect is good.It is conventional to close down into vapour, air bleeding valve and the defoaming side for adding in fermentation tank defoamer
Method, can produce preferable eradicating efficacy to a small amount of bubble in fermentation process, be produced when there is substantial amounts of bubble in fermentation process
And accumulation, conventional debubbling method are bad to the eradicating efficacy of bubble, sent out especially for high density common in the industry is showed
Ferment process, conventional debubbling method effect can be hindered.The utility model defoaming device is during the fermentation successively
By semicircle silk screen, wavy rough circular orifice plate, conical baffled, corrugated plating group and circular overhead gage to fermentation
During caused bubble eliminated.It is disappeared before bubble overflows tank body by inertia and surface contact action
Remove, so as to reduce the race liquid phenomenon of fermentation process, improve defoaming effect.
2) the longer work period.The utility model defoaming device, using baffle plate, equal orifice plate and silk screen by simply propping up
Frame is arranged on the top of fermentation tank, effectively prevent suppression of the addition to thalli growth of defoamer, will not be delayed fermentation week
Phase, and can be cleaned automatically by the spray head of installation so that the defoaming device has the longer work period.
3) simple in construction and energy consumption is small.The installation that part is defoamed by multilayer reaches preferable defoaming effect, compared to conventional
Defoaming device structure it is simpler, the defoaming device does not need additional motor, reduces process energy consumption.
