Description

The Rotating Trays Weight Grader carries each piece in its own tray, weighs it and drops it into the matching discharge hopper. Because products do not run on a belt, the machine suits softer, thinner and more viscous items that are hard to grade on conventional belt graders: fruit and vegetables, poultry (chicken legs, wings and pieces), seafood (sea cucumber, giant squid, squid slices, abalone, small fish, shrimp), Chinese herbs, egg yolk and other irregular materials.

Grading capacity

Infeed hoppers come in four sizes (small, medium, large and extra large), in stainless steel or plastic. The machine can be configured with 4 to 16 grade levels and 36 to 92 hoppers, reaching up to 300 pcs/min with accuracy down to ±0.3 g.

Construction

The drum motor and the whole machine are SUS304 stainless steel, waterproof and resistant to seawater corrosion, meeting IP65 or higher. The design follows food and drug hygiene standards and helps products meet HACCP and IFS requirements as well as CE and FDA standards.

Control and reporting

  • 10-inch colour touchscreen with password protection and 100 product presets
  • Frequency-controlled motor with adjustable speed
  • Manual or automatic zero tracking
  • 365 days of production data, exportable to USB
  • Excel reports with individual and total weight for each discharge hopper
  • Standard data interface; one computer can control several graders centrally
