SmartLine Grader

Superior accuracy minimizes giveaway and maximizes value

  • Industry-leading technology minimizes giveaway and maximizes throughput
  • Unique open-frame design maximizes uptime and food safety
  • Multiple configurations and applications give optimal flexibility
  • Quality build ensures better return on investment


The SmartLine Grader batches fresh and frozen poultry pieces of almost any size for retail, catering and further processing. It creates simple batches based on piece weight, count or minimum weight. In addition, it can intelligently create batches with fixed weight.

Minimal giveaway, maximum value

Industry-leading technology allows the SmartLine Grader to give a more accurate piece weight and higher throughput than any comparable system on the market. It ensures unbeatably low giveaway and creates batches that get the most value from raw material. Ultimately, the combination of speed and accuracy makes order fulfillment easier and considerably more precise.

Optimal uptime

A unique open-frame design gives full access and ensures the machine can be quickly stripped down and reassembled to make servicing quicker and easier, ensuring minimal downtime. It also significantly reduces cleaning time and maximizes hygiene during high-pressure wash-down.

Unrivaled grading flexibility

With its modular design, the SmartLine can be configured to meet virtually any grading requirement. Height, belt width, bins and receivers can be tailored for almost every need. Numerous infeed and take-away accessories are also available to assist with packing and styling into boxes and trays. When combined with the system’s wide variety of grading applications, it gives complete flexibility to meet customer requirements and respond quickly to changing market demands.

A secure investment

Precision design and quality build mean that the SmartLine Grader is built to last. This not only makes it a more sustainable investment but, when combined with industry-leading technology, ensures a better return on investment.


  • Innovative technology filters out vibration disturbance to give more accurate piece weight
  • Advanced dynamic weighing unit gives flexibility to run different sized products simultaneously if required
  • State-of-the-art tracking in discharge unit ensures better product handling during grading
  • Adjustable grading arms allow handling of both robust and fragile materials
  • Intuitive touchscreen operation


Single lane

The single-lane SmartLine Grader can be equipped with gates on both sides of its belt.

Dual Lane

The dual-lane SmartLine Grader features two belts to handle higher capacities. Each belt has its own independent row of output bins on the side.

Twin Lane

The twin lane custom configuration enables batching from two separate streams of raw material, e.g., different sizes or flocks. The two lanes work together to produce specified batches. Products are discharged into bins or chutes between the two belts. This setup has a significant impact on the batching performance as it allows the batching algorithm to select individual items from a wider selection of raw material to fulfill the required orders. The SmartLine Grader with twin lanes creates batches from two streams of products, doubling the number of pieces to choose from for each batch. One stream with lightweight products and a second stream with heavier products can be blended to create a batch with optimum yield.


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.


Marel offers a range of service solutions to prevent failures, maximize performance or in case of unexpected breakdowns remote or onsite assistance.
