Hygenic Design

Regardless of whether it concerns instant drinks, baby powder or blood bags – for all applications in the food, cosmetics or pharmaceutical industry – the highest requirements for quality and purity are to be met. Especially gaining a predefined quality of the mixture which can be reliably reproduced without any crosscontamination is of utmost importance.

A homogeneous mixture of edicts with varying characteristics such as chemical composition, particle size or aggregate status is required for all processes. Which at first glance sounds trivial may turn out as being very complex especially in mixes having components with very low concentration referred to the total batch.

As an example, mixtures for pharmaceutical tablets prove the importance of reproducible set concentration of the active ingredient referred to the substrate material, as every single tablet needs to have exactly the identical composition of the recipe components within a narrow tolerance.

For mixtures consisting of solid components only the single particles have to change place with its neighbour as often as each component is homogeneously distributed throughout the mixture. Is the formulation containing liquid components, too, such transfer processes support the complete dispersion.

Maximum efficiency of the process along with very gentle treatment of the mixture are significant characteristics for the well-proved high efficiency MTI Universal Mixer model Uni tec®. These machines are operated in batch mode with volumes from 25 up to 2000 litres.

The mixing tool close to the mixer bottom provides at a three-dimensional mixing vortex a peripheral speed of 5 to 8 m/s, thus generated fluidisation expands the product volume, having positive influence on processes of transposition and mass transport. With cycle times of only 1 to 5 minutes and by mixing with very low specific energy demand of approx. 0.1 kW/kg highest mixing quality can be obtained even for most sensitive products having ingredients with different properties regarding bulk densities or surface structures.

The design of the MTI Universal Mixer almost eliminates dead spots in the processing area. The customised machine layout considers typical requirements such as surfaces with a roughness depth of Ra < 0,8 μm, seals with FDA certificate or stainless steel in high qualities.

Hygienic design combined with possible semiautomatic or fully-automatic cleaning present a practice and application oriented mixing system. Individual WIP or CIP systems – adapted to the machine and specific customer needs – are offered by partner companies.
