Powder agglomeration for easier handling and excellent dispersibility

At GEA we supply various agglomeration plants for food ingredients. All plants are designed to meet the industry's strictest requirements for product quality, plant performance and hygienic design.

Key requirements of any food ingredient are that it must be easy to handle within an automated process and rapidly dispersed within the finished product. Agglomeration transforms the fine powders produced in a spray dryer making them ‘instant’ by ensuring faster dispersion and dissolution during processing. Agglomeration also reduces the bulk density of the powder, makes it flow more easily, and helps to reduce dust thereby lowering maintenance and cleaning costs. We have many years of experience during which we have perfected the art of spray drying and agglomeration to meet product requirements, economic demands and the needs of our customers’ plant. Our product specialists and plant designers build these factors into the process when designing plants to meet your needs. 

Single step agglomeration

Our FSD® Spray Dryer combines spray drying and fluid-bed drying to create agglomerated powders from a liquid feed, ready to be dissolved in water. This is achieved by recirculating the fine particles to collide with the feed spray from the nozzles until the required level of agglomeration is achieved.

Two step agglomeration

Powders from traditional spray dryers producing single particles can be ’made instant’ in a special agglomeration plant. The REWET AGGLOMERATOR® converts fine powders from a spray dryer into coarse, instant, free-flowing and dustless agglomerated powders. Agglomeration is achieved through the application of steam and a binder in a controlled environment according to the desired properties of the end product. Any powder that is below the required particle size is sieved and returned to the powder feed system.

Test facilities

We provide test facilities to you for product and process development and validation. This allows you to reduce both process risk and time to market. Through a feasibility study we can help you establish whether a product can be successfully agglomerated. In addition, a product sample can be analyzed with the aim of making a draft proposal for an industrial production process. Pilot tests are used to obtain the basic design data needed for drying a new or existing product and/or optimizing production processes. At our dedicated analytics laboratory, product characteristics such as solids content and particle size distribution can be analyzed.
