Abstract
System and method for processing raw shrimp. A head-on shell-on shrimp is first back-slit to expose the vein. Next, the head and some or all of the vein is removed in a hydraulic deheader. The headless, back-slit shrimp is then peeled in a roller-type peeling machine to remove the shell and any residual vein and provide high-quality, peeled and deveined shrimp meat.
Claims4
A method for processing a raw shrimp, comprising:
- cutting a slit in the back of a raw, head-on shrimp through the shell only deep enough to expose the vein to produce a head-on, back-slit shrimp;
- subjecting the head-on, back-slit shrimp to a turbulent flow of water to remove the head and at least some of the vein from the head-on, back-slit shrimp to produce a headless shrimp with residual shell;
- removing residual shell and vein from the headless shrimp in a roller-type peeler.
A shrimp-processing system comprising:
- a back cutter cutting a slit in the back of a raw, head-on shrimp only deep enough to expose the vein;
- a hydraulic deheader receiving the raw, head-on shrimp and subjecting it to a turbulent flow of water to remove the head and at least some of the vein from the head-on, back-slit shrimp to produce a headless shrimp with residual shell;
- a roller-type peeler receiving the headless shrimp and peeling residual shell and vein from the headless shrimp.
