Internal Baffles

Internal baffles are engineered plates or vanes installed radially along the inner surface of rotary blanching drums. They create controlled turbulence and cascading action for uniform blanching by lifting and tumbling produce as the drum rotates, ensuring consistent exposure to steam or hot water while preventing product clumping and optimizing heat transfer efficiency.

As the drum rotates, baffles lift produce from the bottom and release it in a cascading motion, creating continuous mixing. This action ensures all surfaces receive equal thermal treatment, prevents localized overheating or under-processing, and maintains consistent product flow through the drum.
