Digital Transformation in Food Sorting and Processing

In the spotlight: digital transformation

Though digital technologies are still young, they are already improving operational efficiencies and have the power to help improve profitability in other ways too. Felix Flemming, Head of Digital at TOMRA Food and Recycling, explains.

Some food processors and packhouses might think that “digital transformation” has nothing to do with them. That it’s something for higher-tech businesses or for a time that hasn’t yet arrived. But the reality is changing fast. In fact, digital transformation is already taking place in processing and packing and delivering competitive advantages.

But what, exactly, is digital transformation? Why is it a mistake to ignore it? And how can it improve day-to-day operational efficiencies and higher-level decision-making?

A journey to greater rewards

When we talk of digital transformation, we mean the process of using digital technologies to change the way business is done. And when we speak of digital technologies, we mean electronic tools or automated systems that generate store, and process data. These technologies are developing so quickly that a “second wave” of digital transformation is currently sweeping through industries, bringing robotics, big data, artificial intelligence, and machine learning.

These technologies are transformational because they can change business processes, business agility, customer relationships, and – of greatest immediate value to processors and packhouses – production efficiency.

There is more to digital transformation, however, than technology. It’s also a cultural change. A mindset. A willingness by businesses to recognize that they could be doing some things better and openmindedness to digital technologies to enable the targeted improvements.

It is also important to understand that digital transformation is a journey. Because technologies and solutions are constantly evolving, progress never ceases. Many digital solutions, for example, will periodically benefit from software updates. This means that digital transformation continually helps businesses futureproof themselves.

A moment of change

Food processors face a moment of change. The industry is poised to take its biggest step forward since automated sorting machines replaced manual sorting. Once again, it is automated sorters that are making the leap possible. These machines routinely collect masses of data about the product they are sorting and grading. This machine data was previously buried, but digitalization makes it accessible and useable, producing useful information about a wide range of factors such as equipment availability, machine uptime, predictive maintenance requirements, throughput, and product quality.

Product quality is of most interest to food processors because this is where their greatest operational challenges are. As well as the headaches caused by significant quality variations from one batch of infeed product to another, there can also be variations within the same batch. Manual sampling methods can misread true batch quality because they only examine a tiny part of the product flow, sometimes missing imperfections and defects clustered in hotspots – but the sorter sees everything and reports precisely on what it finds.

First digital tools for processing

The industry leader in sorting, grading, and packing solutions, TOMRA Food, has been on its digital transformation journey for five years. Knowing that digital solutions will be a key enabler of efficient food production – and that reducing food waste is becoming increasingly important, both for economic and environmental reasons – TOMRA has committed considerable effort to build the foundations of its first digital technologies to support customers. This has resulted in TOMRA’s Digital Operations Center; TOMRA Remote Assist for technical support; and the TOMRA Visual Assist Augmented Reality tool. This foundation also serves as the basis to offer artificial intelligence and deep learning solutions for TOMRA Food’s sorting and grading equipment.

TOMRA’s Digital Operations Center can remotely monitor equipment to provide customers feedback if unusual behavior is observed. Taking this one step further, TOMRA Remote Assist enables TOMRA service engineers to log into the customer’s machine remotely to provide faster technical support, eliminating or reducing downtime. And going another step further, TOMRA Visual Assist is an easy-to-use app that enables TOMRA’s remote experts to provide specialist support to a customer or service engineer just as if they were standing in front of the customer’s machine. This makes it possible to solve broad-ranging problems of different complexity remotely.

No special equipment is needed for TOMRA Visual Assist, only a mobile phone with a camera. The TOMRA expert sends an invitation to the on-site customer technician, or one of TOMRA’s on-site Field Service Engineers, to initiate the session. Then the app seamlessly links the technician or engineer to a call with the TOMRA expert best suited to help with the specific problem. The technician or engineer can choose to use Smart Glasses for Augmented Reality remote intervention, which leaves them hands-free for working on the machine. TOMRA Visual Assist is also a valuable training tool.
