Oyster Grader

Precisely size-graded oysters

Lizotte has successfully developed the optimal lighting chamber to acquire high-resolution images in order to precisely grade oysters by size without being affected by the product’s shadow.



The Lizotte Oyster Grader uses custom-developed artificial vision software to provide reliable grading results based on size. Software and equipment design may be modified to suit the specific needs of a particular customer. It processes 3 pieces per second per lane and rejects the defective oyster to ensure that only top quality product is sent to the market. This system is fully food grade and ready for harsh wash-down environment.

Lizotte specializes in custom-built equipment. Hence, we would be pleased to supply a personalized system that would fulfill your operational requirements.
