INDUSTRY COMPONENT

Internal Baffles

Internal baffles are structural components inside rotary blanching drums that control product movement and heat distribution during vegetable and fruit processing.

Component Specifications

Definition
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.
Working Principle
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.
Materials
Food-grade stainless steel (AISI 304 or 316), polished to Ra ≤ 0.8 μm surface finish. Thickness: 2-4 mm. Must withstand temperatures up to 120°C and resist corrosion from acidic produce and cleaning chemicals.

Frequently Asked Questions

How do baffle design affect blanching efficiency?

Baffle height and angle determine product lift height and residence time. Optimal design ensures complete product turnover without excessive mechanical damage.

What maintenance do internal baffles require?

Regular inspection for wear, corrosion, and weld integrity. Cleaning after each batch to prevent biofilm formation and cross-contamination.
