Processing Natural Products

A frequent application is drying and cooling of amino acids or proteins. Protein processing is used in the food sector for confectionery, seasoning or health drinks. The number of applications requires a high flexibility in terms of process layout. It can be generally said that not only cooling, drying and heating are important process steps, but also the product changes taking place simultaneously. As a result, the amino acids are chemically changed or modified in the paddle dryer, creating new desired characteristics.

Crystallizing Polymers

A further application for paddle dryers is to heat material that is then kept at a constant temperature for a certain period of time. The plastics industry uses this process to allow polymers to crystallize further, for example. At an advanced stage of crystallization, the characteristics of the monopolymer, copolymer or terpolymer change, enable new, improved products to be manufactured with these modified substances.

Keeping the Temperature

In addition to drying, the heat transfer area can also be used for other temperature dependent procedures. For example, materials can be reacted in the dryer or modified in terms of their chemical structure. The latter can be a crystallization process, but also a destructive process. The powder’s initial structure is destroyed — a substance that irritates the skin is treated in such a way that its irritant effect is reduced or allayed while retaining its effectiveness.
