Baader 487 Fish Roller Grader

This machine is used for grading herrings or mackerels, i.e. pelagic fish, as well as small to medium-sized whitefish (e.g. Alaska pollack and the like).
Inclined conical slideways are formed by rotating rollers of 3m or 4m in length. Via a chute, these slideways are continuously fed with fish which glide downward and are transferred according to their thickness (and thus their size) to separate conveyor belts or containers. Grading is possible within 4 to 5 size ranges. In order to prevent the fish from accumulating or lying in a transverse position, guide rails with knuckles are arranged above the rotating rollers so that all fish are guided in longitudinal direction through the grading system. Water spraying nozzles wet the rollers.
