Abstract
A crab eviscerating disc is used in a crab processing machine and a method for processing a crab to a market condition. The disc is used to mill a groove along the underside of a crab body without completely cutting the crab body. Each tooth on that disc has a cut clearance angle of zero degree, and a hook angle of zero degree. Because of these teeth, the depth of the groove is limited by a bony plate and a bony ridge in the crab body. The visceral cavities of the crab body are cleaned by high pressure water sprays oriented in the groove while the crab body is still attached.

A crab processing machine for eviscerating and cleaning crabs, comprising in series;
- an infeed conveyor, a carapace removing and body grooving station, a high pressure water cleaning station and a body separating station;
- and wherein said carapace removing and body grooving station comprises an eviscerating disc being configured for milling a groove along the underside of a crab body, said disc comprising:
- a circular shape;
- a plurality of teeth extending along a circumference thereof;
- each of said teeth being formed by two radial cutting edges extending radially relative to said circular shape;
- said two cutting edges being joined by a third cutting edge extending transversely between said two radial cutting edges and defining a tip of said tooth;
- each of said teeth having a cut clearance angle of zero degree, and a hook angle of zero degree.
