Our intelligent Innova software provides real-time monitoring and control capabilities throughout the process along with all-important traceability and tracking features.

There are two essential components in all belt grading systems:

  • Dynamic weigher—an ultra-robust, high-accuracy weigher, which can be customized to handle various weight ranges and throughput
  • Discharge unit—tailor-made to fit customer requirements. A wide range of accessories is available for example, bag holders, batching bins, and chutes.

Marel Belt Graders are equipped with a user-friendly graphical interface that greatly reduces the possibility of human error.


Real-time monitoring with Innova

Innova Food Processing Software controls the grading process by setting up grading programs. Innova provides a comprehensive real-time reporting function that gives the operator a complete overview of the production process. Real-time data generates reports on weight distribution, average weights, a packing overview and packing list, as well as the standard overview and lists. This data can be viewed via dashboards.

Based on these valuable KPIs provided by Innova, you can make intelligent decisions on how to optimize your grading and batching results.

Module losses in production are recorded with the optional Innova Overall Equipment Effectiveness (OEE). The reasons for any stoppages are then collated so that it is easy to identify and track the most common causes of lost production time.
