Abstract
The utility model discloses an automatic pH value control system for the fermentation process of a fermentation tank, which comprises a first pH electrode, the first pH electrode is arranged in the fermentation tank and connected to a controller, which comprises a comparison unit for internally setting a target value (i.e. an ideal pH value) and a control unit, the comparison unit is used for comparing the output value of the first pH electrode and the set target value, and the control unit can feed a moderate amount of neutralizer into the fermentation tank according to the result of the comparison unit. The automatic pH value control system can always control the pH value in the fermentation tank within an appropriate range, thus greatly increase the output of a single tank.
Description
Technical field
The utility model relates to a kind of ferment tank process pH value automatic control device.
Background technology
Traditional zymotic process substratum generally by culture medium raw material add sheet alkali, light calcium carbonate is prepared.Thereby cause the earlier fermentation material liquid pH value higher, generally come the buffer pH value with lime carbonate.Next fermenting process pH value is uncontrollable, depends on the metabolic condition of bacterial classification fully.Its drawback is apparent: early stage, higher pH obviously suppressed the normal growth of bacterial classification, and along with the prolongation in cycle, the organic acid that metabolism produces could reduce the pH value of fermented liquid, but the pH value is difficult to be controlled in the optimum range.This is the deficiencies in the prior art.
The utility model content
The technical problems to be solved in the utility model provides a kind of ferment tank process pH value automatic control device, and the pH value in the automatic control device control fermentor tank is in the suitable scope, has guaranteed the normal growth of bacterial classification, has improved bacterial classification output.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of ferment tank process pH value automatic control device, comprise the pH electrode one that is arranged in fermentor tank, it is characterized in that: described pH electrode one is connected to controller, described controller comprises the comparing unit and the control unit of target setting value, described comparing unit is used for comparison pH electrode one output valve and target setting value, and described control unit is controlled an amount of neutralizing agent according to the comparing unit result and is transported to described fermentor tank.
As the technical program is further limited, described controller also comprises display unit, is used to show pH electrode one output valve.
As the technical program is further limited, described pH electrode one outer setting has the pH electrode sheath.
Compared with prior art, advantage of the present utility model and positively effect are: the pH value of pH electrode one test fermentor tank, test value is sent to controller to be shown, the controller comparing unit is used for comparison pH electrode one output valve and target setting value, and the controller control unit is controlled an amount of neutralizer according to the comparing unit result and is transported to fermentor tank.PH value in the utility model automatic control device control fermentor tank is in the suitable scope all the time, has guaranteed the normal growth of bacterial classification, has improved bacterial classification output.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Among the figure, 1, fermentor tank, 2, pH electrode 1, controller, 4, the neutralizing agent jar, 5, magnetic valve.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is done further to describe in detail.
Referring to Fig. 1, the utility model comprises the pH electrode 1 that is arranged in fermentor tank 1, and described pH electrode one 2 outer setting have the pH electrode sheath.PH electrode 1 is provided with the pH electrode sheath, pH electrode 1 is connected to controller 3, controller 3 comprises comparing unit and control unit, comparing unit is used for comparison pH electrode one 2 output valves and target setting value, and control unit is controlled an amount of neutralizing agent according to the comparing unit result and is transported to fermentor tank 1.Controller also 3 also comprises display unit, is used to show the measured value of pH electrode one.Fermentor tank 1 and neutralizing agent jar 4 are controlled conductings by magnetic valve 5 or are closed.
Workflow of the present utility model is: substratum ferments in fermentor tank 1, pH electrode one is transported to controller 3 with the pH value that records and shows by display unit, when the pH value that records when pH electrode one reaches a certain value, open controller 3, by the comparing unit in the controller 3 pH value in the fermentor tank 1 and target setting value are compared, according to comparative result by the conducting of control unit control magnetic valve 5 with close, thereby utilize the neutralizing agent in the neutralizing agent jar 4 to adjust the interior pH value of fermentor tank.PH value in the fermentor tank is in the proper range all the time, has guaranteed the growth of bacterial classification, and actual output is improved largely.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited only to above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also belong to protection domain of the present utility model.
