The twin-shaft Pegasus® Mixer has established its reputation as a veritable workhorse in the product range supplied by Dinnissen Process Technology. Dinnissen is a specialist in precisely mixing and dosing raw ingredients in quantities ranging from very small to very large as well as doing so in accordance with very strict hygienic requirements with the help of the Pegasus® Mixer. Dinnissen is now introducing a new line of Sustainable Pegasus® Mixers which make energy savings of up to 60% possible for mixing processes. In doing so, Dinnissen is responding to client demand for process technology which is sustainable and economical.

The Pegasus® Mixer is an accurate and efficient mixer which is fitted with a twin-shaft mixing mechanism rotating in the opposite direction. As a result, a unique fluidized zone is created during the mixing process which lies at the heart of the entire mixing concept. The twin-shaft mixing mechanism throws the raw ingredient particles lightly and loosely upwards with a vertical acceleration equal to the force of gravity (Froude number = ca 1). The process of causing the particles to float in air is extremely energy-efficient. This principle is the first step towards realizing overall energy savings of 60%. In addition, a situation in which the raw material particles are floating gently through the mixer is ideally suited to spraying powders and liquids onto the particles. As a result, the raw materials which need to be added and mixed in are distributed over the floating particles as soon as they are fed into the mixer.
The new series of Sustainable Pegasus® Mixers makes it possible to reduce mixing times to one third of the mixing times that can be realized using traditional ribbon mixers or single-shaft mixers. Reducing the mixing time further reduces energy consumption by 30% to 40%. In addition, the short mixing time makes it possible to increase capacity by 15% to 20%.
