Abstract

A crab extractor including opposed, large cylindrical rollers oriented in vertically superimposed relation with the lower roller being perforated. Cleaned, uncooked crabs which have been broken along a longitudinal center line from front to rear along the bottom are fed between the rollers with the feelers first by a belt conveyor. The rollers are driven which forces crab meat through the perforations or holes in the bottom roller which is scraped off by a doctor blade into an ager which conveys the extracted meat to a point of discharge. The shell components of the crab are not forced through the perforations and are scraped off of both rollers by doctor blades onto a conveyor. The rollers are interconnected by large meshing gears at one end thereof in order to rotate both rollers at the same speed in opposite directions. The lower roller is driven which in turn drives the upper roller and the auger which conveys the extracted meat from interiorally of the bottom roller is independently powered.
