    • A plug screw feeder (1) comprises a plug screw (10) with a thread (12) and a plug screw housing (20) surrounding the plug screw. The plug screw housing comprises an inlet opening (24) in a side of the plug screw and in a vicinity of a first axial end (18) of the plug screw. The plug screw is arranged for feeding lignocellulosic biomass material (99) from the inlet opening to a second axial end (19) of the plug screw when being rotated. The thread, in at least a part of an inlet section (15) of the plug screw, presents a jagged peripheral rim (14A) with an inwards directed leading edge. The inlet section is defined as the section of the plug screw passing the inlet opening during rotation. A feeding arrangement and system for treatment of lignocellulosic biomass material comprising such a plug screw feeder is also disclosed.
    • 插头螺旋供料器(1)包括具有螺纹(12)的插塞螺钉(10)和围绕插塞螺钉的插塞螺钉外壳(20)。 插头螺钉外壳包括在插头螺钉的侧面中并且在插头螺钉的第一轴向端部(18)附近的入口开口(24)。 插头螺杆被布置用于在旋转时将木质纤维素生物质材料(99)从入口开口供给到插头螺杆的第二轴向端部(19)。 该螺纹在插头螺钉的入口部分(15)的至少一部分中呈现具有向内定向的前缘的锯齿状周边缘(14A)。 入口部分被定义为在旋转期间通过入口开口的螺旋塞的部分。 还公开了一种用于处理木质纤维素生物质材料的供给装置和系统,其包括这种螺塞螺旋送料器。
