Exalant process: Advanced drying technology for optimal efficiency

Advanced drying technology

The Exalant process contains several components to build the complete drying solution. The technology is built on liquid evaporation by heat energy and a gas to carry the moisture away. Most commonly used is air to carry the heat energy and the moisture, but other gas types can be used, such as superheated steam, inert gas, depending on the specific requirements of the material being dried.

Optimized moisture removal for efficient drying

Once the moisture has evaporated, a carrier gas, typically air, is used to remove the water vapor from the drying chamber. This gas is either blown through or passed over the material, picking up the moisture and carrying it away. The flow rate and temperature of the gas is adjusted to control the drying rate, ensuring that the material is dried efficiently and uniformly.

Precision drying for diverse industrial applications

The choice of parameters depends on the specific material being dried, the desired moisture content, and the application for which the dried material is intended. By adjusting these parameters, a drying system can be optimized for a wide range of industrial processes, from food production to pharmaceuticals and chemical processing.

The Exalant process

AIR SUPPLY

The inlet air passes a filter where particles are separated to avoid contamination of the product.

HEAT EXCHANGER / PRE HEATER

If heat recovery is installed the air continues though a heat exchanger where it is pre heated. Other resources of pre heating can also be used such us residual steam, flue gas etc.

HOT AIR GENERATOR

In the hot air generator the air is heated to selected drying temperature. Normally gas or oil is used as fuel but steam or electricity can also be used. Indirect or direct heating can be used.

EXAFLASH™ DRYER

Product to be dried is feed into a feeding bin. A screw feeds the product into the drying chamber. The drying chamber is equipped with a rotor to disintegrate the wet product.

PRODUCT SEPARATION

The dry product is separated from the moist air by cyclones or filter.

PRODUCT COOLER

Product is discharged from the cyclones/filter into a cooling system to lower the temperature and avoid problems with handling and condensation in downstream process. Cooling system is of pneumatic type and air is used as media.

HEAT RECOVERY

Filtered exhaust air leaves the product separation and passes a heat exchanger to recover heat energy.

EXHAUST AIR TREATMENT

The air could optionally pass an air treatment system to prevent odour and emissions. Several types of air treatment is available such as filter, scrubber, biofilter, ozon etc.
