Contract drying is a matter of trust

Customers who put their raw materials in our hands are playing safe because spray drying has been our strength and core competency for many, many years. For more than 40 years, we have been drying a broad range of products from difference product groups including protein hydrolysates, tea extracts, natural colors, flavors, soy sauces, yeast extracts, vitamins and minerals on behalf of our customers.

Specialist for spray drying of food as contract drying

Our international clients from the food and ingredients industry know us as a competent problem solving and highly specialized company. We can offer the processes needed for the processing of water-soluble extracts, aqueous solutions, multi-component mixes and emulsions. This also applies to the processing of natural products where the product properties will vary depending on the time of harvest or region of origin. With our long-term experience, we are able to meet the agreed specifications for such products as well.

Optimal preparation of the raw materials before spray drying

The optimal preparation of the raw materials before spray drying is a decisive factor for the quality of the spray-dried end product. Our supplemental services for the pre and post treatment of products comprise the optimized dissolution of the supplied solid raw materials and the treatment of liquid raw materials ranging from homogenization and emulsification to cooling and heating to the standardization of the final product. For each contract drying project, we first select the optimum individual combination of these technological possibilities at the Uelzen site in order to obtain a perfect starting point for the subsequent drying process. 

Individualized processes for spray drying of food

Our special strength is the development of an optimally suited processing process for every individual spray-dry product. Depending on the product and initial raw materials, we use various spraying technologies including centrifugal or nozzle spray drying. This allows us to control the different physical parameters of a powder precisely according to the customer requirements.The entire process of a spray drying project is accompanied by an interdisciplinary team consisting of sales, product development, laboratory and production. At the beginning there is a detailed project briefing in close consultation with the customer. This is followed by recipe development and evaluation of an optimal processing method.

Controlled production and certified processes for your contract drying

Of course we hold all major certifications - from ISO 9001 to Kosher and Halal. Our own in-house laboratories closely monitor incoming raw materials, the production process and the end products. Sophisticated cleaning processes as well as tower utilization and zoning concepts additionally ensure a maximum of safety in all production steps of the contract drying. At some of the towers we implement high-care requirements for particularly sensitive products such as vitamins and minerals for baby and special foods.

Contract drying of protein hydrolysates

The contract drying of protein hydrolysates requires special attention in terms of solubility, sensory properties and structure of the final spray-dried product.

Contract drying of tea extracts

Decisive quality parameters in the spray drying process of black or green tea extracts are solubility, structure of the powder and sensory properties of the spray-dried product.

Contract drying of natural colors

In the spray drying of vegetable colors such as carrot juice extract or beetroot extract the standardization of the products is very challenging because of the harvest-related natural fluctuations.

Contract drying of flavors

For the spray drying of flavors we develop recipes with different carrier combinations. The selection of the right carrier material ensures that the flavor-providing aroma components of the product are optimally protected by a kind of "encapsulation".

Contract drying of soy sauce powder

We dry various grades of soy sauce on carriers with different color and flavor intensities for use in the food industry. For soy sauce powders, special requirements in terms of flowability, solubility and sensory properties have to be fulfilled.

Contract drying of yeast extracts

We dry various grades of yeast from different sources for industrial food applications. A precise control of the spray drying process is used to optimize flowability, dust reduction and hygroscopicity.

Contract drying of vitamins and minerals

We spray vitamins and minerals as functional components in different ratios with various carrier systems. This facilitates amongst others the handling in industrial processing.
