Question

Which of the following is best suited for evaporating tomato puree?

• A. Jacketed open kettle evaporator
• B. Climbing film evaporator
• C. Falling film evaporator
• D. Plate type evaporator

Hint:

While film evaporators are more efficient for water-like liquids, thick purees require the mechanical handling provided by kettles or forced-circulation evaporators.

Answer 1

The Correct Option is A

Tomato puree is thick and viscous, and thin film equipment like climbing or falling film evaporators struggle to spread such a heavy product evenly across their surfaces without it scorching. A jacketed open kettle avoids this problem because it comes with built in agitation, keeping the thick puree constantly moving so it heats evenly and does not stick or burn at the edges. This makes the jacketed kettle the practical choice for evaporating something as viscous as tomato puree.
