FIELD: process engineering.
SUBSTANCE: invention relates to solid particles processing in liquefied bed used in chemical and pharmaceutical production lines. This disc (3) consists of several top discs (7) and bottom discs (6) shaped to ring. Note here that every top disc (7) overlaps concentrically the part of one or several bottom discs (6). Barriers (13a, 13b) are arranged between said top and bottom discs (7) and (6) to make therewith the multiple passages (16) for medium (9).
EFFECT: improved process performances owing to circular displacement of material in process chamber.
