Abstract
The utility model discloses a novel sampling device among bacterium liquid fermentation, include steam conduit, sampling channel who is connected through the tee bend and the check valve that communicates with the fermentation cylinder, be provided with the air intake valve on the steam conduit, be provided with the sample connection bottom the last sample cock that is provided with of sampling channel, sampling channel, the check valve bottom is provided with the bleed valve. The beneficial effects of the utility model are that: the utility model discloses the sample of being convenient for, effective anti -pollution sample connection adopts steam sterilization simultaneously, and the risk of microbiological contamination very easily when having reduced fermented sample reaches and sterilizes completely, has characteristics easy and simple to handle simultaneously.
Description
Technical field
The utility model relates to the Novel sampling device in the fermentation of a kind of bacterial liquid.
Background technology
At present in microbial liquid industrial fermentation, fermentation liquor sampling detection is an important link, is also the link that in whole sweat, a gnotobasis contact is extraneous.In the prior art, fermentation tank sample position has two kinds usually: a kind of sample position, at fermenter base, is called " lower sampling "; Another kind of sample position, on fermentation tank top, is called " upper sampling ".Time employing " lower sampling ", sealing is poor, vulnerable to pollution; When adopting " upper sampling ", stopple coupon is inserted therein from fermentation tank top, utilizes the gaseous tension that in fermentation tank, fermentation is formed fermentation liquor to be extruded sampling from stopple coupon, although this kind of structure is easy to operate, but the fermentation broth sample vulnerable to pollution extruded can not reuse, causes larger waste.In addition, because stopple coupon inserts fermentation liquor depths from top to bottom, also fermentation liquor is left in stopple coupon after sampling, this fermentation liquor rests in stopple coupon, fully can not mix with fermentation liquor in tank, the truth of fermentation liquor in fermentation tank can not be represented again, therefore, during sampling, all will say that this Partial fermentation liquid bleeds off.The sampling frequency of major part fermentation is all higher, and the fermentation liquor capacity bled off is comparatively large, causes larger waste, strengthens production cost.
How therefore a kind of integral asepsis be provided, sampler easy and simple to handle is the problem that those skilled in the art need solution badly.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of integral asepsis, easy and simple to handle, the Novel sampling device wasted in less bacterial liquid fermentation.
The utility model is realized by following measures:
Novel sampling device in a kind of bacterial liquid fermentation of the present utility model, comprise the jet chimney, sampling pipe and the non-return valve that is communicated with fermentation tank that are connected by threeway, described jet chimney is provided with air intake valve, described sampling pipe is provided with sample cock, be provided with sample connection bottom sampling pipe, bottom described non-return valve, be provided with air release.
Above-mentioned sampling pipe is positioned at below jet chimney.
The material of above-mentioned jet chimney, sampling pipe and sample connection is food-grade stainless steel.
The beneficial effects of the utility model are: the utility model is convenient to sampling, and effective anti-pollution sample tap, adopts steam sterilizing simultaneously, decrease the risk of very easily microbiological contamination when fermentation samples, reach complete sterilizing, have feature easy and simple to handle simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 be jet chimney, 2 be air intake valve, 3 be threeway, 4 be sample cock, 5 be non-return valve, 6 be air release, 7 be fermentation tank, 8 be sampling pipe, 9 for valve switch, 10 sample connections.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, Novel sampling device in a kind of bacterial liquid fermentation of the present utility model, comprise the jet chimney 1, sampling pipe 8 and the non-return valve 5 that is communicated with fermentation tank 7 that are connected by threeway 3, jet chimney 1 is provided with air intake valve 2, sampling pipe 8 is provided with sample cock 4, be provided with sample connection 10 bottom sampling pipe 8, bottom non-return valve 5, be provided with air release 6.Sampling pipe 8 is positioned at below jet chimney 1.The material of jet chimney 1, sampling pipe 8 and sample connection 10 is food-grade stainless steel.
Its course of work is:
In a, sweat, open the air intake valve 2 on jet chimney 1, the sample cock 4 of sampling pipe 8 and the air release 6 of non-return valve 5 lower end all the time.
B, sampling start, and place the container collecting discarded fermentation liquor at sample connection 10.
The air release 6 of c, first closedown non-return valve 5 lower end.
Gas admittance valve on d, steam off pipeline 1.
E, turn on the valve switch 9 of non-return valve 5 upper end.
F, discard just start flow out the fermentation liquor with residual moisture in pipeline.
G, until fermentation flow velocity stable and pure after collect fermentation liquor in cleaning sterile container.
H, sampling terminate, and close the sample cock 4 of sampling pipe 8.
I, tighten the valve switch 9 of non-return valve 5 upper end.
J, open the air release 6 of non-return valve 5 lower end, open the sample cock 4 of sampling pipe 8.
K, open the gas admittance valve of jet chimney 1, make vapours carry out steam sterilizing by sampling pipe 8, sample tap, non-return valve 5 and air release 6.
The discarded fermentation liquor that l, process are collected.
The utility model, by jet chimney 1 and fermentation tank 7 non-return valve 5, by the steam sterilizing adopted, decreases the risk of very easily microbiological contamination when fermentation samples, reaches complete sterilizing, have feature easy and simple to handle simultaneously.The material of jet chimney 1 is food-grade stainless steel, has the advantage of corrosion-and high-temp-resistant.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
