Your powders and granulates in trusted hands

Whether you’re in food, nutritional supplements or pharmaceuticals, your order is in good hands with us. Since our founding in 1996 we’ve invested continuously in technologies, capacity and people. This has let us turn SternMaid into one of Europe’s leading contract manufacturers. Powders and granulates are our focus. Our services extend from raw materials sourcing, to blending and packaging, to warehousing and logistics.

Customer wishes – the basis for investments

Our production facility in Wittenburg near Hamburg is one of the most advanced of its kind, and has been expanded and upgraded several times in response to customer wishes. Today, at our 60,000 sqm site we run state-of-the-art and certified lines for a wide variety of blending orders, and lines for packaging product in different kinds of shelf-ready retail packs. There is also a special warehouse where we safely store sensitive powder blends for you for call-off orders.

The heart of our technology park is the fluidised bed plant.

We can do more than just blending. At the centre of SternMaid operations is the fluidised bed plant in which we enhance your products. It combines a wide range of technical possibilities, and is configured specifically for the many and varying requirements of contract manufacturing. Whether by drying, granulating, agglomerating or coating, we give your blend that special something, for example a functional protective coating or microencapsulation of vitamins and micronutrients so they are released only where they benefit the body. We also have a small laboratory-scale fluidised bed plant. With it, we make small sample batches for testing before going to industrial scale later on. If desired, we also offer help in developing products that make use of our fluidised bed capabilities.
