Onion and seed drying and storage with desiccant dehumidifiers is very effective. When storing any agricultural product you will need constant temperatures and humidities. A desiccant dehumidifier can provide this for you. A refrigerant dehumidifier would not be able to work effectively below 70º. So a desiccant dehumidifier which would not freeze since it removes the moisture in the form of a gas would be the best most efficient choice. |
