For the storage and processing of fresh goods we rely on ventilation technology (adding fresh air) for several reasons: discharging of the generated CO2 and ethylene, especially with fruits, oxygen supply for staff making long shifts in the processing hall, and the most extensive application: drying tubers such as onions and potatoes.

Drying tubers

For mechanical harvesting, which might damage the produce, and/or harvesting wet goods, ventilation is necessary to enable wound healing and drying. Next to that, fresh air can also be used for cooling, also known as ‘free cooling’ as one relies on freely available cooling capacity.

Discharging CO2 and ethylene

Fresh produce breathes and therefore produces CO2. Some fruits produce ethylene as part of the aging/rotting process. A minimal amount of fresh air is needed to discharge these gasses.

Oxygen for people

There is a guideline for the amount of necessary oxygen for working staff. A ventilation system should meet these requirements. If it fails to do so, people will suffer from headaches or get droopy.

Your advantages with ventilation technology by Geerlofs:

  • The best for your produce. Longstanding cooperation with leading agricultural companies has resulted in the best design for your fresh produce. Less dehydration and longer freshness, even after a longer storage time between harvests. This means higher revenue for you.
  • One control system for everything. With our Gispro® control system in combination with hardware such as fans, pressure walls, hatches, mechanical cooling and optional air heaters or ULO equipment, the storage of fresh goods can be controlled perfectly. Fans, inlet and outlet valves, mechanical cooling and auxiliary equipment can be controlled using one touch screen display.
  • User-friendly controls
  • Countless possibilities to store and analyse data
  • By combining mechanical cooling and ventilation technology, one creates the option to cool mostly with fresh air and, hence to use ‘free’ cooling energy. This, of course, saves you energy and ensures that the process is completed without much dehydration.
