Anhydro Evaporation Technologies The optimum choice of evaporation technology depends on factors such as viscosity and thermal characteristics of the product, the required output rate, and the available energy supply. Evaporation techniques include single-pass or circulation, single or multiple effect, and thermal or mechanical vapour recompression. P R I M A RY P R O C E S S – FA L L I N G F I L M E VA P O R AT I O N Falling film evaporation is widely applied for concentration of low to medium viscosity organic and inorganic products. Anhydro falling film evaporators offer: Concentrate • Low...

Beside direct steam heating Anhydro falling film evaporators apply two vapour recompression SPX FLOW can provide pre-heaters and heat treatment units techniques, to minimise the energy consumption: for all evaporation applications: Direct or indirect steam heating tubular and plate designs with or without heat regeneration. Very gentle preheating can be achieved in systems with small temperature differences such as multi-effect systems with Mechanical vapour recompression requires little or no steam and thermal or mechanical vapour recompression. delivers substantial operational cost savings...

Anhydro Drying Technologies The optimum choice of drying technology depends on the characteristics of the feed product: • High- and low-viscosity liquids and heat sensitive products are spray dried. • Cohesive and non-cohesive filler cakes are spin flash dried. • Granulates and powders are fluid bed dried.

Anhydro Spray Drying Plants For drying of solutions, emulsions, suspensions, and slurries. Spray drying is a continuous process converting a pumpable liquid into a particulate matter in a single operation. The liquid is atomized into very fine droplets in a drying chamber, where PLANT D E S IG N SPX FLOW plant design is based on experience gained from many thousands of tests and a very large number of reference plants installed within the chemical industry. evaporation takes place by contact with hot air, and a powder is Plant configurations are carefully selected to provide the required powder...

Atomization - The Heart of the Process SPX FLOW offers two basic types of Anhydro atomizers: • Centrifugal atomizers, accelerating and atomizing the liquid feed using centri­ ugal force in a spinning disc. Suitable for f many chemical appli­ ations and available for feed rates up to c 80 tons/h. • Nozzle atomizers, spraying the liquid feed under high pressure or using compressed air. High pressure nozzle atomization is used in particular when a coarse powder with narrow particle size distribution and high bulk density is required. The highly successful track record of Anhydro atomizers is based...

Anhydro Spin Flash® Drying Plants The Anhydro spin flash® drying plant is patented and widely adopted by customers within the chemical industry all over the world. Anhydro spin flash® drying solutions are designed for continuous drying of pastes and filter cakes, as well as highviscosity liquids. Anhydro spin flash® drying solutions are available with capacities ranging from a few kilos up to 40 tons powder per hour. Po w d e r outlet The continuous spin flash® drying process offers many decisive benefits: The feed material is screw-fed to the compact drying chamber • High drying efficiency providing...

Anhydro Fluid Bed Plants The Anhydro fluid bed plants are designed for a numerous applications, such as drying, cooling, agglomeration, coating, and product mixing. The process takes place by fluidizing the feed material in a controlled air flow, determined by the particle size and bulk density of the feed material. The process is very well suited for heat sensitive materials. Plugflow fluid beds with a large number of sections leading the product through a long and narrow pass are used for products with requirements of a well defined residence time. Fluid Bed Backmix fluid beds of square or...
