ABSTRACT:
Apparatus and method are disclosed for continuously processing seafood products, to rapidly chill such products for subsequent freezing or for fresh shipment. Container means are provided for receiving the food product together with an aqueous bath for enveloping such product. The container means, which may comprise a plurality of trays or buckets, are carried by a conveyor belt means from the input to output end of the apparatus. Means overlying the moving containers deposit a frozen CO.sub.2 cloud into the aqueous enveloping bath to thereby render such bath an ice-water slurry. Means are further provided for agitating the ice-water slurry in the container means during movement through the apparatus, to promote uniformity in the enveloping bath and to promote cooling contact between the food product and the enveloping slurry. Food products are thereby chilled at typical rates in the range from about 1.degree. F per half-second to 1.degree. F per 8 seconds, with e.g. a relatively optimal rate of about 1.degree. F per 4 seconds being achieved for a typical food product, such as a medium size oyster.
