Abstract
Intelligent feeding-system is controlled based on pH the invention discloses one kind, including, pH input modules, for setting the pH in Zymolysis Equipment；PH detectors, control unit is transmitted to for determining the pH value in Zymolysis Equipment, and by pH value data；Frequency-variable controller, for controlling the rotating speed of feed supplement pump；Control unit, receive pH value data, and measure pH value is compared with default pH value data, if both mismatch and measure pH value is more than default pH value data, the frequency of frequency-variable controller is then adjusted, the working frequency of feed supplement pump is lowered into an increment, if both mismatch and measure pH value is less than default pH value data, the frequency of frequency-variable controller is then adjusted, the working frequency of feed supplement pump is raised into an increment.The present invention ensures that pH controls are in default scope in fermentation process.
Description
Technical field
Intelligent feeding-system is controlled based on pH the present invention relates to one kind.
Background technology
Feeding medium during fermentation employs some fed-batch techniques at present, has continuous stream to add, noncontinuum flow adds, and has constant speed stream to add, index
51) stream adds, particularly in lactic acid, citric acid, fumaric acid fermentation process, pH value influences the growth of strain, it is therefore desirable to adds alkali
Liquid controls the pH value in zymotic fluid.
The content of the invention
Intelligent feeding-system is controlled based on pH the invention provides one kind.
In order to solve the above problems, the technical solution adopted in the present invention is such, and one kind is mended based on pH control intelligence
Material system, including,
PH input modules, for setting the pH of fermentation；
PH detectors, control unit is transmitted to for determining the pH value in Zymolysis Equipment, and by pH value data；
Frequency-variable controller, for controlling the rotating speed of feed supplement pump；
Control unit, pH value data are received, and measure pH value is compared with default pH value data, if both mismatch and surveyed
Determine pH value and be more than default pH value data, then adjust the frequency of frequency-variable controller, the working frequency of feed supplement pump is lowered into an increment, such as
Both fruits mismatch and measure pH value is less than default pH value data, then the frequency of frequency-variable controller are adjusted, by the work of feed supplement pump
Frequency raises an increment.
Preferably, in addition to measure Zymolysis Equipment in temperature TEMP instrument.
Preferably, the dissolved oxygen sensing instrument of the DO values in addition in measure Zymolysis Equipment.
Preferably, in addition to single-chip microcomputer the display screen for display dissolved oxygen, pH value and the temperature of being connected
Beneficial effect：The present invention first presets the pH in each stage of fermenting, and the pH and each stage detected according to pH detectors is pre-
If pH go to compare, and then the alkali number that fills into is controlled, so as to ensure that pH controls are in default scope in fermentation process.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, the embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention..
One kind controls intelligent feeding-system based on pH, including,
PH input modules, for setting the pH of fermentation；
PH detectors, control unit is transmitted to for determining the pH value in Zymolysis Equipment, and by pH value data；
Frequency-variable controller, for controlling the rotating speed of feed supplement pump；
Control unit, pH value data are received, and measure pH value is compared with default pH value data, if both mismatch and surveyed
Determine pH value and be more than default pH value data, then adjust the frequency of frequency-variable controller, the working frequency of feed supplement pump is lowered into an increment, such as
Both fruits mismatch and measure pH value is less than default pH value data, then the frequency of frequency-variable controller are adjusted, by the work of feed supplement pump
Frequency raises an increment.
Preferably, in addition to measure Zymolysis Equipment in temperature TEMP instrument.
Preferably, the dissolved oxygen sensing instrument of the DO values in addition in measure Zymolysis Equipment.
Preferably, in addition to single-chip microcomputer the display screen for display dissolved oxygen, pH value and the temperature of being connected
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
