Description
Technical field
The utility model belongs to quick detection device technical field, and in particular to a kind of refractometer inductive probe.
Background technique
It is well known that, as microorganism constantly breeds, energy source (culture medium) is also in microbial fermentation production process
It is consumed constantly, if supplemented not in time, the growth and breeding of microorganism will slow down or stagnate, but be not that feed supplement is mended more
It is much better, it because feed supplement is too many, will cause overnutrition, will affect the normal breeding and metabolism of microorganism instead.Culture medium needs
How much supplement is just to know to train in fermentor according to the instant sugared content value in the fermentation liquid measured using sugared content as foundation
The amount that base is short of is supported, fills into required culture medium in time by feeding-system.The standard of feed supplement amount will be directly affected due to surveying sugar
True property, and feed supplement influences the quality of fermentation liquid, so sugared content value becomes one for fermentation success or failure in accurate detection fermentation liquid
A key point.
China's fermentation industry occupies an important position in national economy, but overall technology level is compared with developed countries also
Biggish gap, that there are raw material availabilities and conversion ratio is low, energy consumption is high, the pollution problems such as again.It is mould in soil both at home and abroad at present
It is still after using traditional timing sampling with potassium ferricyanide method, anthracene copper ratio that methods and techniques used in sugar are surveyed in plain fermentation process
Color method or fehling reagent titration.Wherein, fehling reagent titration specifically: polysaccharide generates glucose, grape after sour water solution
It can be by the Cu in fehling reagent under aldehyde radical alkaline condition in sugar2+It restores and generates copper oxidule precipitation, it is remaining in fehling reagent
Cu2+Iodine is precipitated with excessive iodate nak response in acid condition, iodine can use sodium thiosulfate standard solution direct titration, according to sulphur
The dosage of sodium thiosulfate can find out the content of total reducing sugar in sample indirectly.However this round-about way seems time-consuming and laborious, obtains
Data also can only as " out-of-date reference " cannot in time, effectively, fermentation liquid sugar amount value in true reflection tank, because according to
It is to need the regular hour that the numerical value measured in this way, which calculates the amount that culture medium in fermentor requires supplementation with, so calculating at this time
Feed supplement amount be not the amount really needed in tank in fact, this always slow half operation clapped undoubtedly will affect fermenting and producing
Quality and yield, also affect entire fermentation industry fermentation level certainly.
Intermittent sample detection exists as following drawbacks: (1) large labor intensity of personnel；(2) continuous sampling causes to expect
The waste of liquid with；(3) the sugar amount value that method measures according to this instructs feed supplement accuracy poor.So being badly in need of a kind of faster more convenient and fast method
It realizes in fermentation process to the on-line monitoring of sugar.
