Flexible all-in-one solution

Marel’s Compact Grader is designed to fulfill the needs of smaller operators and larger ones when requiring an excess capacity to handle temporary or seasonal overflows.

It consists of an infeed section, dynamic weighing and discharge with optional grading and batching processes for catch-weight and fixed-weight batching.

The Compact Grader will handle many poultry products, fresh or frozen: whole grillers, front halves, saddles, butterflies, split breasts, whole legs, thighs, drums, whole wings, breast fillets, leg meat and thigh fillets.
Featuring a wide belt and high throughput, it can grade product of up to 3 kilos [6.6 lbs] weight.

From grading to batching

When optional automatic batching bins and tables are added to the system, the Compact Grader becomes a batching solution that ensures best fit batching with minimal giveaway. Timely opening and closing of the batching bins is needed to keep batches of products together. For this, operators are supported by a batching light button on the bin. This process provides maximum throughput and doesn’t waste any time.

Advanced technology

Plug and play software is included. Processors can make the most of their Compact Grader right away, setting up multiple programs and monitoring the process. The user-friendly graphical interface of the M2400 display can control more than 50 grading programs. Connection to Innova Food Processing Software gives access to continuous data collection, real-time monitoring, easy-to-understand reporting and traceability throughout the process.

Plug and play

The Compact Grader is easy to install and operate. It includes a dynamic weighing platform that filters out disturbances and automatically adjusts the weighing process.
Thanks to its telescopic legs, the Compact Grader is adjustable in height, so that good working ergonomics are always guaranteed.
The Compact Grader comes in three versions, each with its own capacity and maximum product size. There’s also a choice of the number of gates, 2x3 or 2x4 gates.

Hygienic and robust design

To meet the most stringent food hygiene requirements, the Marel Compact Grader allows for trouble-free and effective cleaning. Smooth, rounded edges minimize areas where food can trap. The Compact Grader is also designed to withstand the high-pressure washdowns of the food processing environment. The Compact Grader is built to maximize operational efficiency and equipment uptime.

Benefits of Innova for graders

  • Real-time monitoring and control with Innova
  • Data collection gives insight to optimize grading
  • Enhances batch traceability and quality assurance

Monitor and control grading

The Innova module for grading lets you monitor and control your processing in real time. The software provides live dashboards showing data for key performance indicators such as weight distribution, giveaway and throughput. They give you a clear overview of actual production and highlight where improvements can be made or whether any corrective action needs to be taken to ensure production is running optimally. Remote program management allows you to control grader settings directly from the office. 

Get operational insight 

Information about all batches produced is collected and stored in the Innova database. Standard reports can then be created giving you an insight into operational performance on a daily, weekly or monthly basis. This statistical analysis takes away the guesswork and allows you to make data-driven decisions to optimize your batching. 

Connect your business 

Innova software can be implemented stand-alone with your Grader or it can be integrated with other Marel processing equipment across a full-line solution. Based on these valuable KPIs provided by Innova, you can make intelligent decisions on how to optimize your grading and batching results.
