FrymaKoruma Vacuum Processing Unit, type Dinex

Innovative vacuum processing technology for the manufacture of emulsions and suspensions over a wide viscosity range.

Key Advantages

• Internal and external homogenising (short loop)
• Pump over/discharge of the product without additional pump
• CIP function via pumping features of the homogeniser (no additional
  booster pump necessary)
• Product hygiene and aseptic design at all stages (GMP)
• Minimization of process/cleaning time due to sophisticated mixing and homogenising technology
• Space-saving temperature control (option)
• Optimum heating/cooling time due to improved macro mixing
• Various homogenisers available
• Excellent product reproducibility
• Smooth processing of the product with low shearing force
• Fine distribution range 10 – 1 µm
• Innovative scraper system for left/right running, easy to clean
• Low minimum batch size
• 100% residue discharge
• Process automation system (PAS 1 can be upgraded as an option)

Functional Description
The homogeniser installed vertically underneath the mixing vessel operates in accordance with the rotor-stator principle. The homogeniser allows the product
to be dispersed or pumped either internally (short loop) or via the external circulation pipeline.

In the rotor/stator, the product is accelerated to a tangential speed of 35 m/sec
by the rotation of the rotor and then braked within a distance of 1 mm back down to 0 m/sec. The shear and transverse forces thus generated in the shear gap
effect a droplet size reduction right down to 1 µm in the case of emulsions.

Liquids and powders are drawn in under vacuum to the homogenizer, where
they are wetted and dispersed. The product is returned to the mixing vessel
for macromixing via the internal or external circulation pipeline.

Compared with other designs, the special design of the spiral mixer has the advantage that dependent on the rotational direction of the stirrer, the product
is transported along the inside walls of the mixing vessel either upwards or downwards. An optimum temperature exchange takes place on the surface of
the walls.

The contour scrapers fitted in the spiral mixer are laid out for both left-hand
and right-hand rotation, and scrape product away from the vessel walls and
accelerate the product in the centre of the mixing vessel.
