Fouling is one of the major problems in milk heating. What will be the probability of fouling of milk in a magnetic induction-based heating system? What are the precautions to be taken in order to reduce/avoid fouling in a magnetic induction-based heating unit for milk?
Hima John, .. If we analyze the composition of foulant material collected from heating surface; principally it will be of denatured pretentious in nature . Milk fouling depends on the deposition of high surface active material (whey protein) temperature and heating surface properties. You may try preheating the milk prior to heating in the induction-based heating system. Provision of stirring the milk and while cleaning ensure complete removal of residues if any from previous batch.
I can say that the extent of fouling is less in induction heating compared to heat exchangers. Serum proteins and ca phosphate causes fouling.
