Driver drives axis and foad hindering blade rotation, on the fine porosity of foam on pulpboard that emit be refined into little foam, and crowded penetrating sprays on the plate of back from the fine porosity, the back realization solution-air first time of breaking is separated, gas after the decomposition, and do not beaten at the retort internal perisporium from centrifugal the getting rid of of the opening periphery of foad hindering blade by the disruptive foam, breaking foam realizes that gas for the second time--liquid separates once more, the gas that is decomposed out from the emission by exhaust pipe of retort top outside jar, liquid after decomposing then drops in the reaction solution, and the foam that impacts once more on the reaction solution is realized gas for the third time--and liquid separates.
Purpose of the present invention can also reach by following approach.
Pulpboard in the foad hindering blade preferably is vertical and axis is affixed.
Fine porosity on the pulpboard can be a kind of oblique circular hole that is raised to the pulpboard inwall from the pulpboard outer wall obliquely; Also can be made up of the R-joining crack between the page or leaf plate that evenly gathers with the blind window form on pulpboard, this R-joining crack is raised to the pulpboard inwall obliquely along the pulpboard outer wall.
This oblique circular hole and R-joining crack can be guaranteed by wherein being impacted on the back plate of foad hindering blade by the foam after the refinement.
This oblique Circularhole diameter and R-joining gap length degree are preferably 8～12 millimeters.
The preferably following expansion of back plate, the upward relative pulpboard inclination of shrink form.
Like this, form between back plate and the pulpboard big little cavity, gas, liquid and the foam be convenient in this cavity spread as early as possible, leave.
In the foad hindering blade on the top board plane to the distance at retort top more preferably greater than 900 millimeters.
The foad hindering blade lower plane is preferably 400～600 millimeters to the distance of retort liquid level.
It is uniform along the axis periphery preferably to have three～six foad hindering blades.
The foad hindering blade turning diameter is preferably 1/4～1/2 of retort internal diameter.
In sum, has following advantage among the present invention compared to existing technology: do not suppressing the foam generation, when making microorganism obtain good growing environment, mechanically stoping foam to emit on continuing near the position at retort top, thereby both effectively stoped the generation of " escaping to overflow " phenomenon that causes fluid loss, for retort has been eliminated a microbiological contamination approach, increase considerably again the retort jar hold in the reaction solution volume take per-cent, test shows, the reaction solution volume can increase more than 30% compared to existing technology, meanwhile, since chemical foam killer subtract with or need not, cause the fermentation unit in reaction solution quality and the reaction solution significantly to improve, thereby under the situation that does not increase any input, tiring of gained reaction solution greatly improves.Be enzyme or microorganism field, especially the antibiotic manufacturing increases income, saves and props up, and increases output, improves the quality, and reducing cost provides a good approach and the corresponding equipment of producing.
