Can the competent members calculate once - crosscheck for me - the needed capacity for a tunnel for fresh french fries, 5.000 kg/u, entering at 25°C, leaving condition of 1°C.

Glycol in at -2°C en 0°C out, air in 5°C, out 1°C. Inside the tunnel 8 fans of 3 kW but motors are outside the tunnel.

We also need to cool down the stainless steel belt which is constantly re-warmed by the warm entering french fries I suppose.

Lenght of the belt? Giving a belt width of 1,5 m.?

Gross guess of me was 80 kW but saw now a proposal of 220 kW with ammonia.
What do you think?
Someone experience with tunnels for french fries?
