Equipment

Four technologies, one decision: which of them fits your product.

Spray dryer — WSD Series

Turns a liquid, a suspension or a slurry into powder in seconds, atomised by rotary disc or nozzle. It sets final moisture, bulk density and particle size.

Typically · milk powder, whey, coffee, extracts, ceramics, pigments

See the data sheet →

Falling film evaporator

Concentrates the product before drying, removing most of the water at a fraction of the energy. One, two or three effects, with thermal vapour recompression (TVR).

Typically · milk, whey, juices, extracts, brines, effluents

See the data sheet →

Flash dryer

Dries filter cakes and wet solids in seconds, conveyed pneumatically in a stream of hot air. Small footprint, continuous operation.

Typically · lithium carbonate, sulphates, starches, kaolin, pigments

See the data sheet →

Rotary dryer

Rotating drum for granular solids and minerals at large scale, direct or indirect contact. Robust, continuous and low maintenance.

Typically · salts, granular minerals, fertilisers, sands

See the data sheet →

Upgrading existing equipment

Is your dryer or evaporator many years old? We upgrade installed machines, ours or anyone else’s: on-site diagnosis with a mass and energy balance, mechanical uprating, automation and replacement of the components that cap output or drive consumption. Less energy and more production, without buying a new plant.

Applications

Drying and evaporation calculator

How much water you have to evaporate, how much powder you get and how much you save by concentrating first. No sign-up.
