The mixing process, developed by the British company Dena Systems, produces nanometric-scale particles of benefit to a number of industries. Aqueous or organic liquids, polymers and even solids can be processed to complete homogeneity within a single pass through the machine.
A series of interchangeable reactors linked by pipework are designed to carry out the mixing functions including shearing, homogenising, blending and emulsifying. Elements within the reactors flex and recoil rapidly when the process material enters, ensuring thorough mixing and consistent particle size reduction. Once material is pumped through the reactors it enters a bead mill where particles are given a polished and rounded surface which inhibits re-agglomeration. Ultrafine particles are of particular benefit to certain industries. A main advantage for pharmaceutical companies are cost savings as a reduced amount of active ingredient is required in each treatment and because the completely enclosed system minimises the need for clean-room facilities. Machines are available in three categories: laboratory scale, pilot scale, and production scale.
