Abstract:

A novel method for automated extraction of crawfish tail meat comprises placing cooked crawfish on a tray having a bottom slot, applying a downward pressure to the cooked crawfish, extending a rotating brush through the bottom slot to urge the cooked crawfish into a horizontally exposed position, extending a rotating blade through the bottom slot to an incision, then applying a vacuum force to the bottom slot simultaneous to an increase in the downward pressure, causing the cooked crawfish to bulge and the tail meat to be extracted through the slot, after which the carcass is ejected. A plurality of trays can either be rotated in a circular path or conveyed along a linear path above the various tools as cooked crawfish are loaded and carcasses are ejected.
