FIELD: transport. ^ SUBSTANCE: proposed conveyor device comprises protective casing (1) working member arranged inside said casing and representing consecutively fitted rotors (3) with concave-surface vanes (4) with their radii of curvature equal to the rotor radius. The casing is enveloped by adiabatic enclosure (2) communicating with vacuum main line incorporating needle-type leak valves controlling the feed of rarefaction into the said adiabatic enclosure the feed of air into the said vacuum main line. The rotor perforated vanes form, with nearby rotor vanes and the casing wall, the chambers communicating the vacuum main line with needle-type leak valves controlling the feed of rarefaction into the said adiabatic enclosure the feed of air into the said vacuum main line. ^ EFFECT: setting and maintaining preset temperature and rarefaction. ^ 1 dwg |
