A deveining brush having a substantially v-shaped cross sectional profile removes a vein from a processed shrimp. The cutting assembly of the machine is provided with a leaf spring which is aligned with the cutter arm of the assembly to ensure that the cutter arm is biased toward the drive wheel, but is done so in a manner which avoids off-axis loading of the cutter arm.

Abstract: A shrimp processing machine and method of processing shrimp are disclosed. The machine uses a reciprocating meat picking assembly which employs power generated by a main drive wheel of the machine to rotate a cam wheel positioned to cause a cam arm of the meat picking assembly to reciprocate relative to the drive wheel. Since meat picking tines are mounted to the cam arm, the meat picking tines move toward and away from, and thus retrieve a shrimp from, the drive wheel upon each rotation of the cam wheel. The machine further includes a deveining brush having a substantially v-shaped cross sectional profile to optimize the operation of removing a vein from a processed shrimp. Moreover, the cutting assembly of the machine is provided with a leaf spring which is aligned with the cutter arm of the assembly to ensure that the cutter arm is biased toward the drive wheel, but is done so in a manner which avoids off-axis loading of the cutter arm.
