Abstract
A method and apparatus for the salting and drying of cleaned and prepared fish, or for the drying of salted fish, by means of a fluidized bed of salt particles suspended within heated and dried air. Split fish, fish fillets, shaped portions of minced fish or whole fish are placed in apertured enclosures which are suspended within a chamber in which a fluidized salt bed has been established, and are conveyed through the fluidized salt bed across the interior of the chamber and exposed to the fluidized salt bed until the desired degree of drying and salting of the fish has been achieved.
Claims19
A method of drying and salting fish in the form of split fish, fish fillets, shaped portions of minced fish, or whole fish, comprising the steps of:
- (a) washing and draining said fish;
- (b) wrapping the fish in fabric material permeable to water;
- (c) arranging said fish with suitably exposed surfaces one next to another in two or more apertured enclosures;
- (d) establishing a fluidized bed of salt particles in a gaseous working fluid within a chamber operative to receive successively at one end thereof a series of said apertured enclosures for vertical suspension within said fluidized bed, said chamber being provided along its interior with means for horizontally advancing apertured enclosures suspended within said chamber through said fluidized bed to the other end of said chamber, where said apertured enclosures are successively removed;
- (e) suspending a first apertured enclosure containing wrapped fish within said chamber at one end thereof so that salt particles within a fluidized bed of salt particles can impinge on a substantial portion of the surface of said wrapped fish in said last-mentioned apertured enclosure when such enclosure holding said wrapped fish is immersed within said fluidized salt bed and advancing said enclosure through said chamber sufficiently to permit the suspension of a second apertured enclosure;
- (f) suspending a second apertured enclosure within said chamber at said one end thereof so that salt particles within a fluidized bed of salt particles can impinge on a substantial portion of the surface of said wrapped fish in said last-mentioned apertured enclosure when such enclosure holding said wrapped fish is immersed within said fluidized salt bed and continuing with the advancement of enclosures through said fluidized salt bed to the other end of said chamber and the introduction of subsequent apertured enclosures into said one end of said chamber until said chamber is fully charged with apertured enclosures of wrapped fish;
- (g) maintaining said enclosures within said chamber until the desired degree of treatment of the fish within said first apertured enclosure has been achieved.
- (h) removing said first enclosure and advancing the remaining enclosures suspended within the chamber one position towards said other end thereof;
- (i) successively removing apertured enclosures from the chamber in the order of their introduction into said chamber by repeated steps similar to step (h), so that each enclosure of wrapped fish has undergone a similar degree of treatment within said fluidized salt bed.
