Status: USED

The Marel Compact Grader 450 (CG450) is a high-speed, dynamic weighing and sorting machine designed primarily for the food processing industry. It is highly favored by small-to-medium-sized operations as a standalone piece, or by larger operations looking to manage temporary or seasonal overflow. It is widely used to sort poultry (such as chicken breast fillets or whole birds), fish (fillets or portions), and meat (like pork chops).

Key features, technical specifications, and benefits of the CG450 include:

Technical Specifications

  • Maximum Product Length: 250 mm (10 in)
  • Maximum Product Width: 250 mm (10 in)
  • Weight Range: 40 g to 3,000 g (varies up to 6,000 g depending on specific sub-configurations)
  • Maximum Throughput: Up to 160 pieces per minute (depending on product size and weight)
  • Gate Configurations: Available in 2×3 (6 gates total) or 2×4 (8 gates total) layouts, discharging to both sides.
  • Gate Division: 475 mm (18.7 in)
  • Adjustable Working Height: 850 mm to 1,250 mm via telescoping legs.

Core Capabilities

  • Dynamic Weighing: The unit features a dynamic weighing platform that filters out background vibrations or line disturbances automatically, ensuring precise weight readings on the fly.
  • Grading and Batching: It transitions seamlessly between basic weight-sorting, piece-count sorting, and «best-fit» intelligent batching. The best-fit algorithm calculates combinations of individual weights to fill a package to an exact target weight, drastically reducing product giveaway.
  • Plug-and-Play Setup: Designed with minimal user friction, the grader features a user-friendly control terminal (such as the M2400) that relies on icon-based menus rather than heavy text, reducing the training curve for operators. It supports over 50 configurable grading programs.

Hygienic Design

  • Built entirely from robust, food-grade stainless steel and plastics.
  • Features smooth, rounded edges to minimize areas where food or bacteria can become trapped.
  • Engineered to withstand the harsh, high-pressure washdowns and chemical cleanings standard in the meat and poultry industries.

Software Integration

The CG450 can be integrated with Marel’s Innova Food Processing Software. This connection enables real-time data collection, continuous performance monitoring, and detailed reporting, which helps plant managers track yield, throughput, and total giveaway.

Optional Add-ons

Depending on production line needs, the basic unit can be upgraded with optional modules:

  • Batching bins with integrated push-buttons and packing tables.
  • Batch light panels (left and right).
  • End-shelves for packing boxes.
  • Conveyor spray units and drip pans.
