A shrimp deveining apparatus includes a housing with an entrance opening f or receiving a shrimp and an exit opening for ejecting the shrimp from the housing after having the shell cut and deveined. Within the housing, a partition extends upwardly from a base and has an arcuate surface for slidably receiving a shrimp thereon. Opposing lever arms are rotatably attached to and carried on opposing sides of the partition for rotation about an axis. Each of the lever arms have their dist al end radially extending beyond the arcuate surface of the partition for cradling the shrim p onto the arcuate surface. As the distal ends are rotated downstream the entrance opening, the distal ends are biased against the shrimp for securing the shrimp therebetwe en while the shrimp slides along the arcuate surface past dorsal and ventral cutting blades. The shrimp continues to be secured within the distal ends while the shrimp is carried past a brush positioned for sweeping of the vein from the now cut shell and thus exposed body of the shrimp. Once the vein has been swept from the severed shrimp, the biasing is reduced and the cut and deveined shrimp is ejected from the housing through the continued action of rotating the lever arm. Using a handle attached to the lever arms, they returned to a starting position for repeating the process with another shrimp.
