In the present embodiment, upper mounted plate 41, overhead gage 42, lower baffle plate 43, bottom plate 44 are all porous plates, select stainless steel or plastics to make.Upper mounted plate 41, overhead gage 42, lower baffle plate 43, the preferred material of bottom plate 44 are porous polyethylene plate, porous polypropylene plate and porous EFTE(polyethylene-polytetrafluoroethyl-ne alkene copolymer) plate.
The quantity of thrust-augmenting nozzle 51 is even number root, and this even number root thrust-augmenting nozzle 51 is the circumference uniform distributions around this stephanoporate round tube 22 and guide shell 21.This even number root thrust-augmenting nozzle 51 all runs through upper mounted plate 41, overhead gage 42, lower baffle plate 43 and bottom plate 44 successively.Upper mounted plate 41 is upwards run through at the top of this even number root thrust-augmenting nozzle 51, and the bottom of this even number root thrust-augmenting nozzle 51 is run through bottom plate 44 downwards.The first ventpipe 52 inserts this even number root thrust-augmenting nozzle 51 spaced reciprocally, and the thrust-augmenting nozzle 51 that is inserted with the thrust-augmenting nozzle 51 of the first ventpipe 52 and is not inserted with the first ventpipe 52 is spaced apart.The top of the first ventpipe 52 communicates with the ventage 11 of tank body 1, to import external oxygen, this bio-reactor is carried out to deep ventilation.Therefore, the height of the first ventpipe 52 end faces is higher than the height of the second ventpipe 53 end faces.
Simultaneously on the tube wall of thrust-augmenting nozzle 51, around thrust-augmenting nozzle 51, be evenly distributed in even column the first radial direction through hole (not shown), described first radial direction through hole of two row of the arbitrary neighborhood layout that is staggered.
Between the end face of the bottom surface of upper mounted plate 41 and bottom plate 44, be filled with the filler 6 that cell culture vector forms, what cell culture vector adopted conventionally is sheet-like fiber carrier.The height d of filler 6 is that h/2 is to 2h/3.Be the end face of filler 6 will be higher than lower baffle plate 43 end faces lower than the bottom surface of overhead gage 42 so that the space in tank body 1 utilized fully.
Simultaneously, the aperture of the porous plate that upper mounted plate 41, overhead gage 42, lower baffle plate 43, bottom plate 44 adopt, and on stephanoporate round tube 22 on the second radial direction through hole and thrust-augmenting nozzle 51 aperture of the first radial direction through hole be all less than the diameter of cell culture vector in filler 6, play the iris action to cell culture vector in filler 6, prevent that in filler 6 cultured cells in cell culture vector is dead because being subject to the effect of multistep speed regulation agitator 3 shearing forces.
In tank body 1, cell culture fluid flows to the back cavity 17 of tank body 1 bottom from thrust-augmenting nozzle 51 and guide shell 21, the swirling flow that cell culture fluid flows downward in each thrust-augmenting nozzle 51, guide shell 21 and the interior formation of stephanoporate round tube 22, this swirling flow flowing downward is gone out from the bottom of each thrust-augmenting nozzle 51 and stephanoporate round tube 22, enters the back cavity 17 of tank body 1 bottom.From each thrust-augmenting nozzle 51 and the swirling flow flowing downward of going out from stephanoporate round tube 22 bottoms, under the effect of multistep speed regulation agitator 3, in back cavity 17 then formed the mobile swirling flow that makes progress.
Because upper mounted plate 41, overhead gage 42, lower baffle plate 43 and bottom plate 44 are all porous plate, this mobile swirling flow that makes progress enters filler 6 from the bottom of bottom plate 44.For the cell in cell culture vector in filler 6 provides nutrition and dissolved oxygen.The continuation of this mobile swirling flow that makes progress is upwards flowed, flow through lower baffle plate 43 and overhead gage 42, then through upper mounted plate 41, be back to the top of tank body 1, complete the once circulation of cell culture fluid in tank body 1.Or from the gap around lower baffle plate 43, overhead gage 42 and upper mounted plate 41 excircles, be back to the top of tank body 1, complete the once circulation of cell culture fluid in tank body 1.
In the present embodiment, by changing the stirring velocity of multistep speed regulation agitator 3, can change the speed that this mobile swirling flow that makes progress moves upward in this filler 6.When multistep speed regulation agitator 3 is during in zero span, in the back cavity 17 of tank body 1 bottom, cannot form the mobile swirling flow that makes progress.When in lowest speed one grade of the speed of rotation of multistep speed regulation agitator 3, this mobile swirling flow that makes progress mobile speed going out a little lower than cell culture vector in filler 6 that make progress, in filler 6, cell culture vector can settle down in tank body 1, forms the training method that similar fixed bed is cultivated.In now flour filler 6, between cell culture vector, there is larger gap, and can observe described cell culture vector and carry out small rocking, this rocking contributes to make cell culture fluid being uniformly distributed in filler 6, more superior than existing fixed bed training method.
The speed of rotation of multistep speed regulation agitator 3 rises, be that the speed of rotation of multistep speed regulation agitator 3 is when N shelves the most at a high speed, this mobile swirling flow that the makes progress settling velocity of mobile speed higher than cell culture vector in filler 6 that make progress, make cell culture vector in filler 6 in suspended state, form the training method that is similar to fluidized-bed.The porous plate adopting due to upper mounted plate 41, overhead gage 42, lower baffle plate 43 and bottom plate 44, its aperture is all less than the diameter of cell culture vector in filler 6, the two-layer obstruct that is subject to overhead gage 42 and upper mounted plate 41 of cell culture vector in filler 6, and can not go out, guaranteed that the top of upper mounted plate 41 end faces is supernatant liquids.
In order to guarantee the speed governing of multistep speed regulation agitator 3, the blade that multistep speed regulation agitator 3 adopts is Ping Ye or propeller shape blade.
This bio-reactor fixed bed training method is main, intermittently change momently the speed of rotation of multistep speed regulation agitator 3, make cell culture vector in flour filler 6 in suspended state, formation is similar to the training method of fluidized-bed, and cell culture fluid and meta-bolites in bio-reactor are homogenized.This bio-reactor preferably program of cultivating can be set as: the training method of fixed bed is cultivated 1-3 hour, and the training method of fluidized-bed is cultivated 1-3 minute, stops stirring 0.5-1 minute, then restarts to utilize the training method of fixed bed to carry out cell cultures.
This bio-reactor can be realized highdensity cell cultures, and cell density can reach 10
8individual/more than ml, and can carry out long-time continuous cultivation, this is to supply with cell culture fluid and dissolved oxygen by the bottom of continuously past tank body 1, the supernatant liquor of the top of tank body 1 output is simultaneously realized.The first radial direction through hole on thrust-augmenting nozzle 51 is constantly sent into cell culture fluid filler 6.The solid product of the metabolism that in filler 6, cell culture vector inner cell produces is simultaneously constantly the second radial direction through hole discharge from stephanoporate round tube 22 under the effect of multistep speed regulation agitator 3, and from bottom plate 44, do not flow out, deposit to the bottom of tank body 1 and discharge, prevent that bottom plate 44 from being stopped up by the solid product of cellular metabolism, affect the generation of the mobile swirling flow that makes progress.On thrust-augmenting nozzle 51, the effect of the first radial direction through hole is: in the vertical direction guarantees the homogeneity of filler 6 inner cell nutrient solutions.Described the first radial direction through hole layout that is staggered, further in the vertical direction guarantees the homogeneity of filler 6 inner cell nutrient solutions.
The oxygen of extraneous input is by the first ventpipe 52, be transported to the bottom of tank body 1, this bio-reactor is carried out to deep ventilation, owing to being subject to the restriction in the aperture of the first radial direction through hole on thrust-augmenting nozzle 51, the bubble that the first ventpipe 52 produces in deep ventilation can't enter filler 6 by the first described radial direction through hole.Described bubble breaks under the stirring of multistep speed regulation agitator 3, formation is dissolved in the dissolved oxygen of cell culture fluid, and enter filler 6 by the bottom of bottom plate 44, cultured cells in cell culture vector in filler 6 is carried out to oxygen supply, to reduce the damage of described bubble to described cell culture vector inner cell.
The height of the end face of the second ventpipe 23, lower than the height of tank body 1 top supernatant liquid liquid level, so that the dissolved oxygen in supernatant liquid is carried out to deep ventilation to this bio-reactor, further guarantees the supply of the oxygen that cell cultures is required.
In filler 6, cell, in cell cultures portion's growth in vivo, has good population effect, difficult drop-off.This bio-reactor is when cultivating to solidify the mode of bed cell, and products of cellular metabolism and dead cell can be discharged by the second radial direction through hole from stephanoporate round tube 22, and are deposited on the bottom of tank body 1.Therefore,, in a kind of bio-reactor of the present utility model, the approach that cell culture fluid enters the solid product discharge filler 6 of filler 6 and cellular metabolism is different.
Because this bio-reactor is also by interior insertion the first ventpipe 52 of the first thrust-augmenting nozzle 51, when having solved the problem of deep ventilation, prevented the damage of bubble to cell in deep ventilation process.Therefore its amplification potential is good, can in this cell cultures bed, realize highdensity cell cultures, and cell density can reach 10
8individual/more than ml.This bio-reactor can also carry out the cell cultures of long-time continuous.This bio-reactor is particularly suitable for serum-free culture, long-time continuous perfusion, long-time harvested cell meta-bolites.
Because this bio-reactor has carried out highdensity cell cultures, therefore in cell cultivation process, because the respiration of cell has produced a large amount of viscous foams, viscous foam is emerged from the gap between upper mounted plate 41 end faces and upper mounted plate 41 and tank body 1 inwall.Due to the entrance of foam output tube 14 higher than the end face of upper mounted plate 41 lower than the liquid level of supernatant liquid.Therefore bubble output hole 14 can be connected with the entrance of a wet cyclone (not shown), condenser mouth 13 is connected with the outlet of this wet cyclone.Like this, can be by wet cyclone by cell cultivation process, the viscous foam producing due to the respiration of cell, and the co 2 removal containing in foam.The effect of filter screen 24 is to prevent that foam return is to the bottom of bio-reactor.
Simultaneously, in the sampling valve port 16 of tank body 1 bottom, insert sampling valve (not shown), the valve rod of described sampling valve is through bottom plate 44, cell in the cell culture vector of filler 6 is carried out to sterile sampling, every sub-sampling only samples several cell culture vectors, sampling amount is few, and the cell culture vector of sampling can carry out cell counting, observation of cell growthhabit.The discharging valve port 15 of tank body 1 bottom is for the discharging after completing in cell cultures.
This bio-reactor can be reused and reach more than 10 times simultaneously, and this greatly reduces costs for scientific effort.More than the volume of this bio-reactor also can reach 500L simultaneously.
