COLD-SIDE TECHNOLOGY


“One of the most


interesting innovations in this segment was the introduction of a self-sanitation system, as a response to the ongoing problem of ice safety,” says Michele Granziera, general manager of Scotsman Industries Singapore. “All manufacturers write in their manuals to make a deep internal sanitation of their ice maker monthly, but only a few users really do it.” “We introduced a chemical-


free, natural self-sanitation system integrated inside the machine, which works automatically and prevents the growth of bacteria, mould, and slime for months,” he adds. “Te main advantage is safety, but there is also a dramatic reduction in maintenance costs, as well as an increase in sustainability through a reduction of chemicals and water usage.”


A SMARTER FUTURE Tis growing level of automation, which is tied in with the development of smart, connected equipment with simpler controls, automated programmes, and data-rich operating parameters. “With the increasing


integration of the Internet of Tings (IoT) and smart kitchens, equipment is becoming much more intelligent, connected and optimized,” Campbell explains. “Tis allows for better monitoring, control, and optimization of cold chain processes, especially in improving efficiency and reducing energy consumption.” “Innovation is heading


towards IoT, natural refrigerants, and better design to reduce costs, and the sector is responding to those changes extremely well,” he adds. Several manufacturers


are increasingly selling connected equipment that collects vast amounts of operational data, which can be used to optimize maintenance schedules of usage patterns, and which can enable operators to make smarter decisions about when and how to use equipment in the most energy efficient way. “We could see artificial


intelligence (AI) using that data to do predictive maintenance,” notes Hartman. “It could


predict when a compressor might need to be replaced, which reduces downtime.”


“Global digitalization is influencing the ice maker segment,” observes Granziera. "Te challenge is connecting the machine to the service network without increasing cost and complexity. We now have a way to connect the machine to the service technicians without the need

of expensive PC boards and complex network connections. Just with a smartphone, the user can send all the information the technician needs.” Smart refrigeration is part of


the trend towards smart kitchens. After decades of stagnation there is the suggestion of a step change in the technology responsible for the cooling process in the future. Magnetic refrigeration technology could change the game. “New technology always


has an impact and magnetic refrigeration using the magnetocaloric effect will make a huge impact on the sector,” explains Campbell. “It’s a few years away yet, but


the use of advanced materials, miniaturization, IoT integration and heat recovery technology will all combine to deliver lower operating costs and much lower environmental impacts.” “A variety of innovative


refrigeration technologies, such as magnetic and membrane- based refrigeration, are being explored and developed,” notes Llewellyn. “Tese technologies promise unique advantages for the future, but they still face significant hurdles that need to be overcome before they can be considered commercially viable.” Michael Flatow FCSI of


Flatow & Drews Consulting in Germany also agrees that magnetic refrigeration could be the next major step forward. “It is one of the most discussed potential step changes,” he says. “It uses the magnetocaloric effect to cool down or heat up a material without harmful refrigerants. If commercialized at scale, it could revolutionize the industry by offering an environmentally friendly, highly efficient alternative to conventional cooling methods." Ultimately, innovation is unstoppable, whether it is a small tweak or a ground- breaking new technology. Te consultant's job is to stay abreast of all the changes and match them to clients’ needs. “Te role of a consultant is always to put the interests of the client first, and thinking of the environment as a client always helps focus the mind,” says Campbell. With that broad mindset


perhaps the needs of operators and the planet are not so far apart after all.
