What causes dishwashing liquid to appear turbid after emulsification, and how to resolve it using equipment adjustments?
Turbidity is typically caused by inadequate emulsification, air bubble entrapment, or improper component dispersion. Corresponding equipment-based solutions are as follows: First, insufficient shear force: Increase the stator-rotor speed by 500-1000rpm (adjusting within 5000-6500rpm) and extend the high-shear time by 10-15 minutes to reduce particle size and improve transparency. Second, air bubble entrapment: Switch to a vacuum emulsifier or increase the vacuum degree to -0.08 to -0.09MPa during emulsification, which eliminates air bubbles. For non-vacuum equipment, reduce stirring speed during the final stage and extend low-speed mixing to allow bubbles to escape. Third, uneven temperature distribution: Check the equipment’s heating system for partial overheating or cold spots, adjust the temperature control precision to ±1℃, and ensure uniform stirring via the scraping wall device to avoid local component aggregation.
