Preface
45% of all beautiful crops that grow on our fields ends up wasted. This not only puts a heavy burden on our environment, but is also unacceptable in a world with a growing population and so many mouths to feed.
Dry Misting is a technology that spreads tiny drops of water in the air, creating a thin layer of mist. As the mist evaporates, the humidity rises and the temperature drops naturally. When applied on fresh products, Dry Misting results in retaining freshness, colour and nutrients. Extending the shelf life of these products up to twice as long and hereby reducing food waste.
At Contronics, we are on a mission is to reduce food waste by applying Dry Misting throughout the entire fresh food supply chain.
Thank you for your purchase and joining us on this mission!

Voorwoord
Vijfenveertig procent van alle prachtige gewassen die op onze velden groeien, worden verspild. Dat trekt niet alleen een zware wissel op ons milieu, maar is ook ontoelaatbaar in een wereld waarvan de bevolking groeit en waarin dus meer monden moeten worden gevoed.
Dry Misting is een technologie waarbij kleine waterdruppels in de lucht worden verspreid, zodat een dunne nevellaag ontstaat. Wanneer de nevel verdampt, stijgt de luchtvochtigheid en daalt de temperatuur op een natuurlijke manier. Dry Misting van versproducten zorgt ervoor dat de producten vers blijven en hun kleur en voedingswaarden behouden. Daardoor wordt de houdbaarheid van deze producten met tot wel een keer verlengd, zodat de voedselverspilling afneemt.
Contronics wil voedselverspilling verminderen door Dry Misting in de gehele toeleveringsketen voor vers voedsel toe te passen.

2.2
Beschrijving
De luchtbevochtiger is bedoeld om vochtige lucht te genereren en vervoeren. Dit gebeurt als volgt:
1
Water wordt naar een intern waterreservoir gevoerd. Overtollig water wordt afgevoerd;
2
Een ventilator zuigt lucht aan naar de luchtbevochtiger. De lucht passeert een filter dat eventuele verontreinigingen verwijdert.
3
Transducers onder het waterreservoir genereren trillingen met hoge frequentie (1,7 MHz);
4
Er worden waterdruppels (1 – 3 µ) boven het wateroppervlak uitgestoten;
5
De waterdruppels vermengen zich met de lucht;
6
De vochtige lucht wordt uit de luchtbevochtiger naar het aangesloten distributiesysteem gevoerd.

2.5
Ozongenerator
De luchtbevochtiger is voorzien van een ozongenerator. Deze component genereert vluchtig ozongas (O3) dat ziekteverwekkers doodt. De ozon wordt door de luchtbevochtiger en het distributiesysteem gevoerd om elke component te desinfecteren.
Let op
Het aantal ozongeneratormodules verschilt per model:
De EP DM4 heeft er 1;
De EP DM8 heeft er 2;
De EP DM12 heeft er 3.
|
|
Raadpleeg alinea 7.4 voor uitleg over het programmeren van de ozongenerator.
