Benefits of a conical screw mixer
The most important benefits of our Vrieco-Nauta® mixer are:
A perfect mixing quality and accuracy for a wide range of powders and liquids
A very gentle mixing with a minimum of product distortion
Flexibility in process with a constant mixing quality in charges from 15 up till 100%
All dynamic and static seals in the product zone are made of food grade materials
(FDA approved)
Cantilevered execution of the mixing screw without bottom bearing
Bottom discharge valve to guarantee a full discharge of the mixer, avoid manual cleaning and minimize the risk of cross contamination between different batches
The design is very suitable for wet cleaning
Wide variety of processes
Vrieco-Nauta® mixers are suitable for a wide range of processing activities, such as:
Mixing of free flowing powders
Moistening of powders
Coating
Granulation
Drying of powders
Mixing of slurries
Expert in mixing technologies
We constantly kept on developing this mixer on aspects as mixing quality, reliability and cleanability which resulted in the
Vrieco-Nauta® conical mixer still being the number one mixer long after its introduction!
Besides low shear mixing, we are also you competent partner in mid shear and high shear mixing technologies.

Convective mixing
The Vrieco-Nauta® conical mixer is a convective mixer with a high mixing efficiency which treats your product gently and guarantees the highest level of mixing accuracy without product distortion.
The Typical speed of the screw is around 70 Rpm and of the arm 1 to 2 Rpm. The Tip speed of the screw can fluctuate between 0.5 and 2m/s, so it is appropiate for all ATEX zones. This insures a good overall movement of the particles and a good mixing without segregation and product damage.
Convective mixing effect
The convective mixing effect is created by the following 3 factors:
Axial mixing by the screw
Radial mixing by shape of the cone
Tangential mixing by the arm
Main features of the Vrieco Nauta® mixer
Mixing accuracy: Materials are mixed to the highest level of accuracy, even if some of the components are only present in minor quantities at a ratio of 1 to 100.000.
Mixer design: Product lines available especially for Pharma and food application in cantilevered execution up till 40.000 litre.
Segregative powders: Due to the mass flow discharge characteristics the Vrieco Nauta is the mixer for segregative powders.
Flexibility in process: The Vrieco Nauta mixer has a flexible working capacity from 10 - 100% of filling rate without loosing its mixing accuracy.
Fragile components: The mixing process is accomplished with a minimal energy input and without generation of heat and without damaging product structures.
Fast and full discharge: Discharge rates up to 45.000 litres/hr are possible. Depending on product characteristics, levels of residues after discharge up till 0.001% can be achieved.
References: Hosokawa offers you their experience of 15.000 successful references.
Cleaning: These conical mixers are easy cleanable either in a dry way using special extra large doors on the vessel or in a wet way using spraying devices.
