Contrast Studies on the Solar Drying Schemes of Eucalypt Timber
This research takes Eucalyptus grandis×E.urophylla timber as materials, making them drying with five kinds of schemes. Five experimental schemes are taken as follows: natural air drying, solar energy with storing heat, solar energy without storing heat, solar energy with electric heating during the day, solar energy during the day and electric heating during the night. Experiments have found that: in normal sunny weather conditions, the temperature of solar drying completely satisfies eucalyptus wood drying demand. Energy saving ratio is above 60%; In weaker solar radiation intensity conditions, drying needs to use auxiliary power. Energy saving ratio is about 47.1%. The period of Solar drying is 3/4~1/3 shorter than that of natural air drying. Dry defects were obviously reduced. It has the good prospects for development.
