How much cooling do i need?

[jclevenger]

Hi everyone,
I need to know how much cooling I need to cool 7500 pounds per hour of cookies from 120 degrees f to 80 degrees f. I have a conveyor running 32 feet per minute and I don't need to remove any humidity, but if I do it's ok. They are relatively dry anyways. I have a space of 30 feet to add a cooling tunnel etc.

2800 kg/h x 2.93 kJ/kg.K x 25 K = 20500 KJ/h = +/- 57 kW + fans + losses = +/- 60 kW.

Then, 2800 kg/h at a speed of 10 m/min gives +/-4.5 kg/m belt. It seems that the cookies will be stacked on each other in a thick layer.

If you can do this at your belt speed and given length can only be said after a practical trial. Theoretical calculation is one thin, practical feasibility is another thing.
