    Re: Ultra low Temp Freezer Design

    Ok Now that I know what it is a local company here had a blast freezer working @ -80, not as large as yours mind you, they directed the cold air over the racks, the room it self tended to stay at apx (-70)+- but the tuna froze verry well.

    Re: Ultra low Temp Freezer Design

    Why going so deep in temperature?
    Is it only for speed reasons?
    You're coming close to use a nitrogen tunnel.
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
