Using spray drying and fluidised bed technology we find the right solution for your drying needs. We also use our expertise to find solutions before market launch of your products.
Contract drying and contract manufacturing
inprotec AG relies on two different technologies to fulfil all our customers’ requirements as a contract dryer and contract manufacturer: spray drying and fluid bed technology.
- Spray drying technology
In classic spray drying, solutions, suspensions or emulsions are processed into fine-grained, free-flowing powders. The respective product is first finely atomised at the top of the spray tower. The resulting spray mist is dried by the hot air stream within seconds during free fall (convection).
- Fluidised bed technology
When fluidised bed technology is used, a gas medium flows through the feedstock and raw materials. This flow puts the particles into a fluidised state - they mix with the medium. The result is a flowable, loosened mass of fine-grained particles, a so-called fluidised bed. In the fluidised bed process, the raw materials are also rapidly dried or refined when processes such as spray granulation, coating or spray agglomeration are used.
In the fluid bed systems of inprotec AG, different process steps can be combined. Our customers can choose between continuous and discontinuous operation, also known as batch operation. In this way, the physical properties of the materials to be processed can be specifically influenced. The result: particle systems of precisely defined size and shape, homogeneous and dust-free. We are happy to fulfil special requests, whether it is taste masking, the controlled delayed release of ingredients or particularly demanding protective coatings.
Our partner concept
And if there is no suitable process yet? Then we develop it together with our customers, whether with spray drying or fluidised bed technology. We have developed our partner concept for this purpose. Its goal: to keep the time span from the idea to the market launch of the product as short as possible through close exchange. Our partners make the decisions together with us and benefit from our many years of in-house expertise.
