| Abstract: | The automatic controlling systems of syrup, brix in the evaporation and pH valves inside the neutralization tube in sugar plants which can be solved by using pressure difference as indirect index of syrup brix,combining with the liquid level regulation of every evaporation pan are introduced. To measure pH, a pair of stibium-calomel detective electrodes are used. The deposition of indisolvable calcium and magnesium salts and other problems existed in pH regulation system off neutralization has been eliminated with appropriate technical measures. |
