Sorry, about that.
Here is a for instance,
Turkey Legs, Cooked to 168F, moved to a blast chill, pre-cooled to appox 18F. Product is smoked on screens, about 12 legs to a screen, each screen is loaded on racks which hold about 8 screens, 12 racks total. No packaging at this point. continuous Ammonia chiller. Racks are loaded and unloaded into the room manually, manual doors as well.
Dear kmerian,
Thks for above but where is the condensation ? what is approx. final product temp ? 4degC ? (some people call -18degC chilling), how long for one cycle ?
It sounds like a batch (ie static) freezer as against a continuous,(eg conveyor fed in/out) system. latter is typically much faster so less side-effects.
I am mainly familiar with seafood / 3 types of batch freezer - (a) basic, empty room with/without fan-driven air flow directed onto product (b) same but additional piping with ammonia cooling so as to speed up freezing, product (in trays) laid onto pipes © railroad design where product is on (racked) trolleys fed in one end in a "line" and removed from opposite.
All 3 have some problems due leakage / opening-closing door interface but condensation mainly on floor / door surround at entrance. usual solution is underfloor heating / automation /plastic curtains /education.
room Insulation problems typically manifest ice condensation at walls, ceilings.
So where is condensation ? . On the product surface? IMEX for freezing, significant condensation / long cycle / overloading > excess ice on product. If no previous problem, suggests change in usual cooling parameters, eg air velocity (if fan-driven system), input temperature, cycle time , product dimensions?
