The Most Versatile Processor of All Time
The Nauta Conical Screw Mixer/Processor is legendary for its brilliant engineering that successfully achieves intimate blending of powders or pastes in a short mixing time. Despite its long history, the Nauta's measured superiority makes it an outstanding performer in current processing environments.
As one of only three global official licensees of Nautamix B.V. (Holland), Gansons has been manufacturing Nauta Processors for over 40 years. With over 1000 Nauta Mixers/Processors sold, we have developed vast knowledge and experience across the broad range of applications that this wonderful machine can easily execute.
With our knowledge, experience, quality, and outstanding customer service, Gansons is the best choice for your next Nauta Conical Screw Mixer/ Processor.
The Gansons Nauta as a mixer
The Gansons Nauta Mixer achieves desired results in an exceptionally short time, mixing as much as 2000 kilograms of materials to a complete homogeneity. Unsurpassed for precision, it blends trace additives to accuracies up to one part in 10,000.
The unique screw flight agitator, rotating on its own axis while orbiting the periphery of the conical tank, sets up three distinct intermixing currents in the batch at the same time. The result is the most thorough blending action obtainable, even in mixing high viscosity materials and ingredients of widely different densities.
No other mixer achieves such complete emulsification of creams, pastes and jellies. Yet the most fragile filaments and flakes are safe in the Gansons Nauta because of its smooth and gentle mixing action. The Gansons Nauta is very successful in mixing pastes, creams, doughs and plastisols, achieving complete emulsification with minimal agitation and practically no aeration. When equipped for vacuum, de-aeration is accomplished while mixing.

But the Nauta does more...a lot more...
The Gansons Nauta as a Versatile Processor
The Gansons Nauta Processor is extremely flexible--various operations can be carried out in equipment effecting considerable savings in labour and investment.
The Gansons Nauta Processor executes variety of processes including agglomeration, coating, crystallization, drying, granulation, homogenizing, impregnation, instantiation, de-aeration, de-dusting, and solid-liquid or solid-solid reaction.
These operations are carried out within short process times and with great energy efficiency.
One of the most favoured unit operations is contact drying either atmospheric or vacuum for a wide range of bulk drugs, dyestuffs, food material, etc. The major advantage and successful application is because of:
- Fast drying of slurries, pastes, solids, to free flowing powders.
- Complete closed system secures environmental protection.
- Low energy consumption.
- Can be combined with inert gas or air percolation drying
- Easy solvent recovery.
- No damage to heat sensitive products.
- Important savings by combining operation like mixing, drying, granulation etc.
- Fast and complete discharge.
- Capacities from 50 liters to 30,000 liters.
- Chemical reactions.
The Nauta can be fabricated with contact parts made out of stainless steel of various grades and carbon steel with or without the inside surface lined with corrosion resisting material in accordance to process requirement. Based on particular process requirements, vessels can be provided with jackets or limpet coils for heating by circulating steam or oil and also cooling. For control and regulation of temperature, thermometers or thermocouples can be placed at any point on the container or the jacket. Vessels are fabricated in accordance to BIS, BS, ASME and other international codes of pressure vessels.
FeaturesA range of vacuum filters is available specially designed to operate in conjunction with Gansons Nauta vacuum dryers. Size and specifications are dependent on product, solvent and volume of vapours to be handled. Automatic reverse jet cleaning systems are standard. Filter body and over are jacketed to avoid condensation of vapours passing through the filter.A ball segment valve of special design is fitted to the bottom or in the wall of the vessel.
For installation into the vessel wall enabling product samples to be taken when the vessel is under full operating conditions.For the elimination of agglomerates and lumps which can occur in certain phases of a process, a lumpbreker can be installed in the wall of the vessel.For addition of liquids to powders or moistening of dry solids, spray nozzles can be installed inside the vessel. The liquid is fed to the nozzle through the hollow shaft of the drive assembly for direct spraying on to the surface of the product.A bacteriologically clean vessel can be obtained when C.I.P. cleaning systems are used for the internal cleaning of the vessel. Available are troll balls, lances and/or spray nozzles fitted in the walls or cover of the vessel.The electrical panel controls all process functions. Available are semi-automatic panels, pushbutton controlled, or when required automatic PLC controlled systems with recorders. For accurate measurement and control of product temperature and process conditions, pressure switches and temperature probes are included as part of the drying system. Conditions for these processes are usually dependent on the physical specification of initial and final product desired and can be determined in our test laboratory by experiment.For process conditions of vacuum or pressure, a domed cover is welded on top of the vessel. Vessel and cover can be designed to withstand bursting pressure of up to 150 psi often required when processing hazardous products. The vessel is jacketed or supplied with limpet coil for heating the product dependent on temperature and pressure, conditions of the heating and medium used.
- Closure against flow of product is possible.
- Sanitary design with inner surfaces polished if required.
- Suitable to operate under full vacuum and pressure condition up to 6 bars.
- Easy to clean.
- Minimum product retention.
Gansons has 8 different models of Nauta Mixers and Processors ranging from a working volume capacity of 5 liters upto 20,000 liters.
