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.

Method and apparatus to extract crawfish tail meat

An improved system and method for fluidizing dry powder-based additives into downhole well operations utilizes a dried, low-volume air stream and an ejector nozzle in order to disperse the powders into a liquid stream. In an embodiment, the system can be placed on a powder blending trailer in order to convey additives directly from bulk transport bins into a liquid stream, through the use of an atmospheric pressure hydration tank fitted with a cyclone separator to ensure an even dispersal into the liquid stream.
