    • A batch type digester for wood chips in which a stream of wood chips is delivered into the center of the top of the digester tank, while liquor is being delivered through a pair of pipes at the top of the tank. Simultaneous with the delivery of the wood chips and liquor, a steam vortex is formed in the upper part of the tank by a plurality of steam jets which are directed downwardly and tangentially and form spiral flow paths below the streams of chips and liquor. The wood chips and liquor are dispersed together and the liquor thoroughly wets the chips. The chips produce a substantially even layer as they fall to the bottom of the tank. The steam vortex maintains a negative relative pressure zone which promotes the dispersion of the stream of chips and the liquor.
    • 一种用于木片的批式蒸煮器,其中将木屑流输送到蒸煮罐顶部的中心,同时通过罐顶部的一对管道输送液体。 与木片和液体的输送同时,通过多个蒸汽喷嘴在罐的上部形成蒸汽涡流,这些蒸汽喷嘴被向下和切向地指向,并在芯片和液体流下方形成螺旋流动路径。 木屑和酒分散在一起,酒液彻底润湿碎片。 当芯片落到罐底部时,芯片产生大致均匀的层。 蒸汽涡流维持负相对压力区,促进碎屑流和液体的分散。
