Characterisation of the Mechanical Properties of Heat-Induced Protein Deposits in Immersed Cleaning Systems

During heat treatment in dairy production, the rapid formation of heat-induced fouling deposits on the plant surface leads to reduced efficiency of heat transfer. Therefore, a regular cleaning process is required to soften the heat-induced protein deposits and then remove them from the plant surface...
