Specialising in contract spray drying of food ingredients and infant food components

With its newest state-of-the-art spray drying plant "Tower 12", Uelzena has once more strenghtened its competence and capacities as a leading contract spray dryer for food ingredients and infant food components such as flavours, vitamins, minerals or colouring plant extracts. A total of four spray towers of different sizes and technical layout are now available at the central production site in Uelzen for the drying of infant food components.

Spray drying under high-care conditions

Highlight of the new plant is the strict hygiene zone concept including hygiene locks for products and staff, efficient containment systems, elaborate cleaning concepts and high-performance air ventilation and filter systems. Everything is embedded in a completely self-contained separate spray drying plant, which is state-of-the-art in terms of hygiene, technology and efficiency. All processing steps are largely automated and recipe controlled to ensure a high product safety. 

Modern spray drying technology

The new plant has a 15 metre high spray tower with a flexible nozzle spraying system and a capacity of 650 - 750 kg of powder per hour. For each of the very different spray products, a separate, specifically customised processing procedure is defined in advance. This is one of the greatest challenges for all contract drying projects and at the same time one of the most valuable core competences of the experienced spray drying specialist Uelzena. 

Optimised concentrate production

The high-performance wet mixing area is equipped with various technologies for preparing the raw materials as well as dustless feeding stations for ingredients and active ingredients. All technologies can be flexibly combined with each other in order to perfectly and individually prepare the very different raw materials. This includes two separate, combinable mixing lines and high-performance high-shear mixers with a dispersing unit for mixing in powders and other raw materials. 

Automated packaging lines

Initially, the powder is filled into big bags directly under the tower. The final packaging in 5 kg to 25 kg aluminium tubular bags (bag-in-box system) then takes place decoupled and downstream on currently two largely automated, separate packaging lines. The filling of big bags and tubular bags takes place under optimum high-care conditions within the plant's strictest hygiene zone. The autonomous packaging lines could also be used for contract packaging of powders into bags.
