Ice cream manufacturer Diplom-Is has for many years delivered ice cream varieties in large volumes and is today a well-established player with strong brands and a production that never stands still. Based in Nittedal, north of Oslo, large quantities of raw materials and finished products are handled every single day – all with a focus on taste, quality, and efficiency.
When producing high-quality ice cream for thousands of customers, there’s no room for failure in production. This places high demands on both precision and hygiene. That’s why it’s very important that all technical components in the process plant work together. And this is where flexible and food-approved hose solutions play a key role – from the first ice cream to the last popsicle.
Lollipop, Krone-Is, Dream Mango & Pasjonsfrukt: How the ice cream classics are made
When Diplom-Is produces popular ice cream varieties such as Lollipop, Krone-Is, Dream Mango & Pasjonsfrukt, it does so with great precision and respect for each individual recipe. Production is automated and based on a combination of modern ice cream technology and practical experience – regardless of whether it’s juice, chocolate or creamy ice cream mixture that’s transported through the hoses.
The handling of raw liquid materials such as ice cream, juice, and chocolate places high demands on both equipment and hygiene. That’s why Diplom-Is uses flexible and pressure-resistant hose types that can withstand both temperature fluctuations and CIP cleaning – without compromising food safety. All hoses are part of a food-approved system solution with full traceability and clear marking, so that each individual component is always used correctly. This ensures both stable operation and peace of mind in everyday use.
Technical interaction all the way through
When ice cream is transported between processing plants, it’s done via Oily Food/SPL hoses, which are also available in a version with a working pressure of up to 15 bar. They ensure that the thick, fatty medium flows stably and safely through the system – even under pressure.
Dynamic hoses, which are flexible and resistant to temperature changes, are used for chocolate handling, while the transparent Plutone PU Press hose is perfect for juice production, where visual control during the process is crucial. All hose solutions are fitted with Tri-Clamp couplings, which make cleaning and maintenance quick and easy. In addition, they come with clear markings so that production employees always know exactly where they belong.
Reliable service and operational reliability in one
Once production is up and running, there should be no unnecessary stoppages. That’s why fast delivery and technical advice are a crucial part of the collaboration. We deliver quickly – even when the need is urgent – and help find the right hose solution for each process line. This applies to the choice of materials, lengths, and coupling types. The result is fewer stoppages, more uptime, and system solutions that can be easily scaled in line with production. All technical components are also adapted to food requirements and cleaning routines.
The technical insight and level of service have made our work easier – we’re very satisfied. It’s clear that we’re dealing with a supplier who understands our needs and can deliver precise hose solutions quickly. The combination of professionalism, flexibility, and availability is very important in a production like ours, where operational reliability is crucial. I also often use their online hose configurator, which makes it easy and quick to configure exactly the hose solution we need – it saves us both time and incorrect orders.
