Heat Pump Grain Dryer Features
Heat pump grain dryers are used for drying agricultural products: corn,maize,wheat,peanuts,oil seed,etc.
The drying process is to remove humidity and prevent the products from fungi or mildew,which provides the possibility of longer time storage.
· The grain dryer equipment has a simple structure; Small volume after dismantling,easy for transportation and movement.
· Equipped with online moisture meter,automatic moisture control to prevent over-drying and weight loss.
· Automatic temperature control system:the hot air temperature and air volume can be adjusted during drying process automatically to ensure the top drying quality.
· Highly automated operation with microcomputer control to reduce labor and improve working efficiency.
· Increased drying area and the drying speed is accelerated.
· Variety of heat sources can be applied,including biomass,fuel,gas,coal,etc.
