Question

Many cereals are made with high moisture content so that the cereal can be formed into various shapes before it is dried. A cereal product containing 58% H2O by mass is produced at the rate of 1000. kg/h. What mass of water must be evaporated per hour if the final product contains only 20.% water?

Answer 1

Answer:

475 kg/h

Explanation:

Hello,

In the attached picture, you're finding a "mass balance" in which you can see:

- Mass balance for water and the total mass, whereas X is the masic flow of the evaporated amount of water and Y the masic flow of the final product.

- Solving for X in the total balance and replacing that equation into the mass balance of water, we can calculate the masic flow of the final product.

- Finally, we place the masic flow of the final product into the eqn (3) to get the masic flow of the evaporated water.

Best regards.
