Roller grader

Designed to grade cod, hake and other fish of similar morphology.

The equipment grades the fish according to size.

It has a conveyor, inclined laterally, and a rotating roller superimposed on it.

The free space between the roller and the conveyor increases progressively along the conveyor.

Smaller fish slide down the gap between the roller and the conveyor in the initial section of the conveyor.

Larger fish continue forward until the gap is sufficient to allow them to pass.

 

Conveyor:

  • Horizontal conveyor with an open structural system. Built with AISI-316 quality stainless steel plate and profiles. Built with sheet and profiles in stainless steel quality AISI-316.
  • Conveyor belt in food-grade PVC.
  • Pulling and tensioning rollers totally manufactured in AISI-316 quality stainless steel and later vulcanized, mounted on polyamide bearings with bearings and seals in stainless steel.
  • Support rollers manufactured in PE, with AISI-316 quality stainless steel rod.
  • Fairing on the rotating elements with a protective casing, built-in AISI-316 quality stainless steel.
  • Structure and legs in plate to facilitate their installation in the ship.
  • Driven by hydraulic motor or electric gear motor, coupled to the traction shaft by means of an elastic stainless steel coupling and Vulcollan star, to give more reliability and durability to the transmission.

 

Grading roller:

  • Grading roller built with stainless steel.
  • Driven by hydraulic motor or electric gear motor, coupled to the traction shaft by means of an elastic stainless steel coupling and Vulcollan star, to give more reliability and durability to the transmission.
  • Fairing on the rotating elements with a protective casing, built-in AISI-316 quality stainless steel.
  • Regulation systems by means of threaded spindles in Stainless Steel, as well as bridges and fastening structure.
  • Water spraying system installed laterally, to facilitate the good operation of the grading system.

 

Dimensions:

  • Built to measure and according to the needs of the project.
    • Indicative dimensions (LxWxH): 4.900 x 1.100 x 700 mm.
