Condensation Drying

In short

Condensation drying dries stored crops using electricity instead of waiting for the right weather. Moist air is drawn through the evaporator, where its moisture condenses out, then reheated with the heat released by the cooling process. An add-on module brings it to Tolsma-Grisnich indirect cooling systems.

Condensation drying is the method for drying both now and in the future.

When drying constantly depends on the weather conditions and preserving the quality of the product is paramount, a condensation drying unit is a clever purchase. An additional module enables the condensation drying to be applied to the current indirect cooling system from Tolsma-Grisnich.

In condensation drying, the moist air is sucked through the evaporator and cooled, condensing and removing the moisture in the air. By reheating the cooled air (with the heat released during the cooling process), the moisture is reabsorbed into the air. The application of condensation drying dries the product faster, prevents fungal growth and ensures that the quality of the product is preserved. Another significant advantage is the reduction in gas costs. It is even more interesting for companies that generate their own energy.

The advantages of condensation drying:

  • Improved product quality
  • Continuous drying
  • Energy-efficient drying, runs entirely on electricity
  • Drying is not weather dependent

Questions about condensation drying

How does condensation drying work?

Moist air is sucked through the evaporator and cooled, so its moisture condenses and is removed. The cooled air is then reheated with the heat released during cooling and takes up moisture from the product again.

Drying no longer depends on the weather and runs continuously, entirely on electricity. It dries the product faster, prevents fungal growth and reduces gas costs.

An additional module applies condensation drying to the current indirect cooling system from Tolsma-Grisnich. See the GCU-I on our refrigeration page.

Our onion store layouts use drying plenums and gas burners, and our gas heaters are also used for grain drying.
