FIELD: roasting.
SUBSTANCE: device comprises horizontal metallic perforated plate mounted in the cylindrical housing. The plate is perforated with openings made of overturned trancated cone. The difference of the diameters of the top and bottom bases of the cone is (0.2-2.15)h, where h is the thickness of the plate. The plate is provided with the peripheral non-perforated ring secured in the ring-shaped member having C-shaped cross-section. The member is made of three coincident metallic rings that abut against the housing and can move with respect to the bottom and top rings and with respect to the intermediate ring of the member within the temperature gap. The top bearing ring is mounted for permitting movement with respect to the housing. The ring is provided with the metallic cylindrical insert that points upward and abuts against the lining. The perforated section of the plate between the openings is provided with stiffening ribs directed downward.
EFFECT: expanded functional capabilities.
