Which one of the following heat exchanger is suitable for continuous production of rice puddings or chocolate-based puddings? A. Plate type heat exchangers B. Scraped surface heat exchangers C. Tubular heat exchangers D. None of the above
Answers
Answer:
Tubular heat exchange.........
The heat exchanger suitable for rice pudding or chocolate-based puddings is Scraped surface heat exchanger (option B).
A scraped surface heat exchanger is used when in a situation when either there is fouling causing the heat transfer rates to drop or there is the presence of viscous fluids which have very low heat transfer rates. Scraped surface heat exchangers can also be used when both of these difficulties occur together.
Rice pudding, chocolate pudding, or other such sweet chocolate-based puddings can be produced using these scraped surface heat exchangers. These exchangers are designed carefully for such applications and also increase the quality of production. These exchangers lead to the continuous production of such puddings.
