Vast Knowledge and Experience for Over 40 Years
Gansons Nauta as a Mixer
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 comprehensive mixing action, even 
while mixing high viscosity materials and ingredients of widely different densities. The most fragile filaments and flakes 
are safe in Gansons Nauta because of its smooth and gentle mixing action. 
Gansons Nauta in very successful in mixing pastes and plastisols. To achieve deaeration while mixing, Gansons Nauta can 
be equipped with vacuum.
Gansons Nauta as a Processor
Gansons Nauta Processor executes a variety of processes including agglomeration, coating, crystallization, drying, 
granulation, homogenizing, impregnation, instantiation, deaeration, de-dusting and solid-liquid or solid-solid 
reaction.
• Fast drying of slurries, pastes, solids, free flowing powders
• Complete closed system secures environmental protection
• Can be combined with inert gas or air percolation drying
• Easy solvent recovery
• No damage to heat sensitive products
• Important savings by combining operations such as mixing, drying and granulation
The fabricated vessels comply with international pressure vessel codes including BIS, BS, ISME and others.
Gansons Nauta as a Dryer
• Vacuum drying and simultaneously homogenizing products
• Vacuum drying of heat sensitive products
• Production of pastes and deaeration under vacuum in order to prevent formation of air bubbles in the
final product
• Reaction under vacuum or pressure of pasty products
• Mixing and reaction of products in an aqueous phase at temperatures above 100°C
• Product reactions under pressure blanketed by inert gas
