摘要:
Apparatus and methods for deheading and peeling shrimp hydraulically using the Venturi Effect. A shrimp-laden fluid is pumped through a conduit system including one or more venturi tubes. The acceleration of the fluid through the venturis detaches the heads and loosens or detaches the shells from the shrimp. The venturis may be used in conjunction with a roller peeler to increase peeling quality. An inspection station receives shrimp from the roller peeler and directs incompletely peeled shrimp back to the peeler or one or more of the venturis.

The invention relates to an apparatus (1) for peeling shrimp (S) comprising (i) a supporting surface(2) for supporting shrimp to be peeled wherein the supporting surface is provided by an endless belt (3) moving through at least a peeling zone (4) of the apparatus, (ii) positioning means for positioning shrimp in a predefined orientation on the endless belt, and (iii) a press member (6) which, for the peeling operation, can exert a pressure force on a supported shrimp. The invention also relates to a method for peeling shrimp.

L'invention se rapporte à un appareil qui sert à extraire la chair de la queue de crustacés comme la crevette. Un exemple de réalisation de l'appareil décrit comprend un bâti (10) sur lequel est placée une bande transporteuse (12), laquelle achemine des organes de support constitués par des cartouches amovibles (26) vers des cylindres d'application de pression (20, 22) entre lesquels passent les cartouches. Le cylindre inférieur (22) est de préférence creux et ajouré, pour que la chair provenant des queues des crevettes fixées aux cartouches soit pressée hors des carapaces des queues et puisse passer à travers le cylindre (22) pour être ensuite recueillie.
摘要:
Shrimp peeling machine (1) including a closed chain (3) including cylindrical rolls (4,5,6), (7) and includes first rolls (4), second rolls (5) and third rolls (6) and where at least the first (4) and second (5) rolls in a limited area—the peeling area (8)—are designed to turn by an activation element (9). The shrimp peeling machine (1) includes a first motor device (10), which drives the activation element (9) and another motor device (11), which drives the chain (3) forwards in the shrimp peeling process direction (7). The activation element (9) includes at least one toothed belt (12) with a first action surface (13) and another action surface (14). The first action surface (13) is with first items (15) in mesh with the first roll (4) and the second action surface (14) is with second items (16) in mesh with the second roll (5).
摘要:
Roller-type peeling apparatus and crowned rollers in the peeling channels of the peeling apparatus. Each peeling channel includes small-diameter insert rollers frictionally counterrotated by simultaneous contact with two large-diameter, rotating powered rollers separated across a gap. Holddowns at spaced locations along the length of the insert rollers hold the insert roller against the two powered rollers and into the mouth of the gap. The insert roller or the powered rollers are crowned between consecutive holddowns to compensate for the tendency of the insert roller to deflect and to provide uniform contact pressure between the insert roller and the powered rollers along the insert roller's length.

The invention relates to apparatus for the extraction of meat from the tails of crustacea such as prawns. An example of the apparatus described comprises a frame (10) supporting a conveyor means (12) which carry support means in the form of releasable cartridges (26) towards pressure applying rollers (20, 22) between which the cartridges pass. The lower roller (22) is preferably hollow and apertured so that the meat from prawn tails secured to the cartridges is pressed out of the tail shells and passes through the roller (22) for collection.

L'appareil décrit, qui sert au décortiquage de crustacés tels que notamment des crevettes, se compose d'une chambre de dosage (3) et d'une chambre de traitement thermique (5) séparées par un clapet coulissant (11) et fermées hermétiquement par des clapets à membranes cylindriques (7, 9). Les crustacés tombent depuis un entonnoir (31) dans la chambre de dosage (3), dont le clapet (7) est fermé. Le clapet coulissant (11) s'ouvre et une partie des animaux tombent dans la chambre de traitement thermique (5), dont le fond est fermé par un autre clapet à membrane (9). Le clapet coulissant (11) se ferme et de la vapeur à pression et à température élevées est amenée dans la chambre de traitement thermique (5). Le clapet à membrane (9) est dépressurisé, après quoi la surpression regnant dans la chambre (5) éjecte les crustacés par l'ouverture de déchargement (19) vers une plaque de séparation par rebondissement (35), grâce à laquelle la chair et les écailles ou la carapace des crustacés se séparent.
