People often enquire about the purpose a wood pellet dryer. A dryer is used to dry up the moisture content inside any materials and it consists of two parts; one is furnace or the heat stove and the other is rotary dryer. A furnace or heat dryer provides heat source to the materials to dry it whereas a rotary dryer uses the hot air from the furnace to dry up the materials moisture to 15%. The sawdust is crushed into smaller particles with the help of a hammer mill and then passed through the dryer. Before passing to the dryer, these particles are subjected in midair with a passage of hot air from the furnace.
From the way the dryer looks like, one will say the dryer is a cylinder which is held up slightly in a slanted position and its rotator speed can be adjusted. The wet raw materials are driven into the dryer where the materials are well spread and dispersed with the help of shoveling plate so that the hot air is introduced well within the dryer. There are certain technical parameters that you need to look out for, before you start operating it. Once the materials are dried, it has to be cooled and then packed so that you get the desired output. Drying is the main part in preparing wood residues for pelleting with desired moisture content in it.
