Regarding the cleaning of pH meters in protein factories
Thread Content
The pH probe in our factory gets clogged with protein solution every few hours, requiring manual cleaning. It’s very time-consuming and labor-intensive. Is there a good way to modify it to achieve better long-term performance?
1) For greasy substances, use raw cotton dipped in acetone or soapy water to remove dirt from the surface of the electrode membrane. (2) If the electrode membrane dries out, immerse the electrode tip in a 0.1 mol/L HCl solution and leave it there for one night. (3) If protein accumulates in the diaphragm, immerse the electrode in an HCL/pepsin solution to remove the deposits. (4) If the electrode is contaminated with silver sulfide, immerse it in a thiourea solution to remove the deposits. Please recalibrate after electrode treatment. Note: Please handle the cleaning fluid or filling liquid in accordance with the regulations for dealing with toxic or corrosive substances; clean it multiple times
An online scrubbing and water spraying system can be installed below the probe
We added flushing water in front of a valve, and that’s what happened in our workshop
Simply put, it involves creating a cleaning bracket, along with a cleaning agent and a control unit. If you also require a sanitary standard, you will likely have to purchase the original bracket from the manufacturer. Some manufacturers have a pH self-cleaning system.
Just add an instrument air timer to blow it periodically
It comes with a self-cleaning bracket, but an air supply source is required on-site; for examples from E+H, models such as CPA475 and 450 can be referenced. . .
How long does it take for the electrode to get clogged with proteins? Could an insertable electrode sleeve be used, one that can be removed online?
The environment for producing electrodes is too poor
