We have done a trolley freezer for a chicken processing factory. The capacity is 12 tons per hour freezing. We noted that when the product is Vaccum packed chicken parts, the freezing capacity is almost 16 tons, but when the 9 piece cut chicken ( i.e 9 parts of the chicken body ) are packed in a plastic bag, there is a lot of air in the bag. ( this goes fro KFC outlets) & the capacity comes down to almost 8 tons per day. The client cant do vacuum packing for these items.

It there any way of increasing the capacity, say putting holes on the platic bag- so that the air does not act as insulation & when the cold air passes over the bag, gets carried away due to pressure differential.

Or any other way?
