Looking for any book about freezing tunnels (-40;-20C)

Hello everyone,

Looking for any book about freezing tunnels with temperature around -40C. ( For example used for meat freezing or ice cream freezing, where the product is inside the freezing facility for some minutes/hours).

I'm speaking about freeze tunnels with like 7x7x7 m size, containing NH3 refrigrant evaporator, and air circulating fans.

I am curious about how to maintain the proper relative humidity to prevent weight (water) loss from the product while freezing , and meanwhile also how to prevent ice build up in the evaporator plates /coils, or on fans with this high humidity and low temperature air.

I'd be happy for any suggestions!

Thanks in advance!
