Drying technology

NIZO food research has a broad knowledge of drying fluid foods. Spray and drum drying equipment are available at pilot scale and can be combined with various computer models and analytics.

NIZO has developed a sustainable technology for the drying of a wide range of products. Do you want to reduce your energy use and costs? Without lowering your output? Then read all about the NIZO Drum Drier.

Spray drying

Spray drying is widely used in the food industry for the production of various powders such as milk or soy powder. NIZO has developed solutions to optimize the spray drying and particle agglomeration process. Therefore, we can create products with instant food properties and a constant quality. We also have expertise in drying complex products, e.g. hygroscopic products, such as protein hydrolysates, and products that cause a lot of fouling, like flavour powders.

Computer models

Application of computer models of the drying processes enables the evaluation of existing drying installations, process optimization and product quality control during the drying process. For example, we have a computer model that can predict the moisture content and energy consumption in a process. CFD models can be applied to calculate product qualities such as fouling and agglomeration.

Analytics

At NIZO, we can make use of several specialized analytics like Automatic Sorption Isotherm Analysis, an analytical tool to determine drying and wetting behaviour, and a method to measure stickiness behaviour based on pressure fluctuations (DyMonT).
