Comparison of Surfactant Performance Using D-LIMONENE According to EO (Ethylene Oxide) Mole Number for Cleaning the Fish Cake Production Process

摘要

The cleaning efficiency of EO (ethylene oxide) 8～9 mole was about 78-80%, it is the best. The highest cleaning efficiency for each EO mole concentration is as follows. The cleaning efficiency was 97% in the surfactant of 4.8% EO 5 mole, the cleaning efficiency was 97% in the surfactant of 7.7% EO 8 mole, and 68% in the surfactant of 7.7% EO 10 mole. The cleaning efficiency was measured using a surfactant with various EO mole. All detergents were tested at 20% surfactant concentration and EO 8 and EO 9 showed the highest cleaning power. In experiments using 8 mole of EO surfactant NPE8, the highest cleaning power was obtained at surfactant concentration of 7.7%. To determine the cause of this, the electrical conductivity of the solution was measured at the concentration of NPE8 at 1.6%, 4.8%, 7.7%, 14.4% and 20%, respectively. After washing the test plate with NPE8, the detergent remaining on the surface of the test plate was analyzed by FT/IR, and it was found that the detergent did not remain.
