Thank you.

I work on the following:
Mass to be frozen = 30.5 Metric Tons
Product = fish Fillets
Freezing time per day = 3hr + 15min for loading and unloading

From this it worked out to be 8 cycles per day.

The weight that will be frozen at each cycle will be 3813kg/cycle.

So I will require 5 x 30 stations plate freezers (vertical plate freezers).

My refrigerant will be Ammonia that will enter the plates at -18C and the fish is +10C.

From what I calculated (which I know I made an error somewhere but do not know where) I get a total refrigerant capacity of 47.21kw. For 1 x 30 station.

The plate freezers will have headers.

According to the suppliers specifications for ammonia the pump circulation rate will be 67 litres / Hour per 1000 K Cals.

How will I know if my refrigeration capacity is adequate enough?
And how do I calculate the pump circulation rate as the litres / Hour per 1000 K Cals confuses me.
, because i know how to convert kW to kCals/h.
