Roller Grading Equipment


Pisces roller graders are design to separate large volumes of fish or shrimp by the width of the product. The product travels down a set of rotating rollers that gradually increase in width between them. The size of the gap and the starting width are determined by the user. The graders are normally accompanied by an infeed hopper, a stand and grade take away conveyors.


HG Series Fish Roller Graders


The HG Series roller grader use two rollers to gently separate the fish in up to four grades. Both the rollers and the grade chutes are adjustable, in order to allow for each customer to customize the grades for their needs. The machine is feed by a vibrating table which ensures the fish fall on to the grader and are not stacked on top of one another. The standard machines are offered with 5 to 13 rollers. Anchovy, Hake, Herring, Mackerel, Sardine, Smelt and other similar species are all currently being processed using the HG series roller graders.

 

PG Series Shrimp Roller Graders


The PG uses four roller with flats on the top set to separate the shrimp. The top set vibrates the shrimp to stop them from stacking up on top of one another. This stops small shrimp from riding a larger shrimp down to the wrong grade. Both the rollers and the grade chutes are adjustable in order to allow for each customer to customize the grades for their needs. The standard size of the graders is from 1 to 6 channels.
