[0002] Internal fouling is common in dairy processing equipment. This deposited dirt can lead to reduced cleaning efficiency, pipe blockage, raw material contamination, and microbial growth. Ultra-high temperature instantaneous sterilization (UHT) (heating temperature 135-150°C, heating time 2-8 seconds) is currently one of the most commonly used sterilization processes in dairy processing. Tubular heat exchangers are often used in the UHT process. During the UHT process, tubular heat exchangers reach temperatures of approximately 140°C, generating stubborn fouling due to protein denaturation and Maillard reactions.
