    • A grain drying tower comprises a heater and blower separating a heating plenum and a cooling plenum. The dryer is provided with a heat reclamation/heat recycling system and/or counter-flow cooling to reduce the energy requirements of the tower dryer. The heat reclamation system comprises a chamber external to the outer wall of the tower and which is and located at a point along the drying path. The bottom of the chamber is open to the atmosphere. Hot exhaust air enters the heat reclamation chamber at the top of the chamber and is drawn back into the tower by the blower as the exhaust air exits the open bottom of the chamber. In the counter-flow, the walls defining the grain path of the in the cooling section are not air permeable, and air is drawn into the cooling section through outer wall ducts which are closed at the inner wall. The entering air travels up through heated grain to be warmed, and then enters the plenum through inner wall ducts, which are closed at the outer wall of the tower.
    • 谷物干燥塔包括加热器和分离加热集气室和冷却风室的鼓风机。 干燥器具有热回收/热回收系统和/或逆流冷却以减少塔式干燥器的能量需求。 热回收系统包括在塔的外壁外部并且位于沿着干燥路径的点处的室。 房间的底部向大气敞开。 热排气进入室顶部的热回收室,当排气从室的开口底部排出时,通过鼓风机被抽回塔中。 在逆流中,限定冷却部分中的颗粒通道的壁不透气,并且空气通过在内壁处封闭的外壁管道被吸入冷却部分。 进入的空气通过加热的颗粒向上行进,以加热,然后通过在塔的外壁处封闭的内壁管道进入增压室。
