    • A method and apparatus for drying material, especially wood particles, having moisture therein, comprising depositing the material to a selected depth onto a transport conveyor (19) at the first end (14) of a drying chamber (12). Heat is applied to the material as it is transported toward the opposite second end (16) of the drying chamber (12) so that, adjacent the second end, the material forms essentially two layers, a first layer having a first level of moisture therein and a second layer having a second level of moisture therein which is different from the moisture content of the first layer. Means (22) are provided adjacent the second end (16) for removing one of the first and second layers from the conveyor (19) and directing that layer exteriorly of the chamber (12). The layer, which has the highest remaining moisture content may be further dried to achieve the desired moisture content.
    • 一种用于干燥在其中具有水分的材料,特别是木材颗粒的方法和装置,包括在干燥室(12)的第一端(14)处将材料沉积到选定的深度到输送输送机(19)上。 当材料被传送到干燥室(12)的相对的第二端(16)时,热量被施加到材料上,使得在第二端附近,材料形成基本上两层,第一层具有第一水平的水分 以及第二层,其具有与第一层的水分含量不同的第二水分含量。 设置在第二端(16)附近的装置(22),用于从传送器(19)移除第一层和第二层中的一个,并将该层引导到室(12)的外部。 可以进一步干燥具有最高剩余水分含量的层以获得所需的水分含量。

    • An agitated bed drying apparatus (20) for particulate material (152) is provided which includes a housing (22) having an elongated, essentially imperforate, flexible bed (24) therein adapted to receive the material (152). An agitator assembly (26) made up of a series of rotatable beater bar units (70) is located below the bed (24) and oriented for repeatedly impacting the bed (24) to establish an undulating bed movement for elevation and tumbling of the particulate material (152). An infrared heating unit array (28) is located above the bed (24) so as to expose the particulate material (152) to IR radiation for most effective drying thereof. Alternately, the bed (24) may be in the form of a length of material (58) mounted in tension and against translation within housing (22), or as a continuous belt (136).
    • 提供了一种用于颗粒材料(152)的搅拌床干燥装置(20),其包括其中适于接纳材料(152)的具有细长的,基本上无孔的柔性床(24)的壳体(22)。 由一系列可旋转的搅拌棒单元(70)组成的搅拌器组件(26)位于床(24)下方并定向成反复冲击床(24)以建立起伏的床运动,用于提升和翻转颗粒 材料(152)。 红外线加热单元阵列(28)位于床(24)上方,以将微粒材料(152)暴露于红外线辐射,以实现其最有效的干燥。 或者,床(24)可以是一定长度的材料(58)的形式,其被安装成在壳体(22)内的张力和平移,或者作为连续带(136)。
