    Hello Jon Pall and other

    Yes, air thawing are widely used, but not enough.

    Years ago i worked for Carnitec (see www.carnitech.dk) with thawing as one
    of my jobs in the develop. dept. Ie design, testing, calculating of
    different thawing units and methods. (Carnitech is a world leader in
    seafood processing equipement, and their delivery programme also includes
    different thawing equipement and methods, incl air thawing.)

    Since i left Carnitech, i have worked as a governmental inspector, with
    approving of HACCPplans, plants, equipement in both Denmark and Greenland,
    and today i run a consultancy company.

    To my experience, a total cost-evaluation air thawing are most profitable
    in thawing "open" products as fillets, peeled shrimp ect. Whole salmon and
    tuna are also better thawed i air. 12 years ago i also worked on squid,
    but i am sorry; i cannot remember which method came out superior. If
    needed, i think i can find the papers again.

    Air thawing have a bad reputation i many industries, but to my opinion, it
    is based on experience of poorly designed equipement, or bad management of
    the equipement.

    Drying of product surfaces can be controlled, but it takes a good design and
    mangement of the equipement.
    A good air thawing unit costs, but this cost comes back as profit throug
    better yeild/less driploss, better product quality etc, but as with other
    things about seafood processing; it has to be designed and used right.
    >From my work as an authority, i have seen a lot of poorly designs,
    resulting in poor yeilds and inferior product quality. In one plant the
    thawing proces used, could cause risks regarding food safety.

    If anybody have further questions, do not hessitate to cantact me.

    Yours

    I have never heard of thawing of seafood with air. Is somebody using this
    method?

    We have used thawing machines which have given us the most control in the
    procedure (time and temperature of thawing).

    Dear members,

    Air thawing is advisable or not. Especially in cuttle fish processing.
    Please tell the advantages and disadvantages.

    With regards
