Pressure sealed high temperature elevating conveyor

A pressure sealed elevating conveyor for non-ambient temperatures to move a material, comprising:

• an elevating conveyor, comprising:
• a rotatable lift tube;
• a drive shaft coupled to the rotatable lift tube allowing material discharging from a top end of the lift tube to pass into a discharge head;
• a static screw disposed within the rotatable lift tube, the static screw comprising a static screw shaft with attached screw flights, wherein a diameter of the rotatable lift tube and a diameter of the static screw are selected to be operable to move a material within the lift tube upward as the rotatable lift tube rotates, wherein the pressure sealed elevating conveyor for non-ambient temperatures further comprises:
• a shroud tube surrounding the rotatable lift tube of the elevating conveyor;
• a feed hopper coupled to a lower end of the shroud tube, wherein a coupling between the feed hopper and the shroud tube is pressure sealed;
• the discharge head having a discharge head top, the discharge head coupled an upper end of the shroud tube and wherein a coupling between the discharge head and the shroud tube is pressure sealed;
• an input port in the feed hopper, the input port operable to receive the material;
• and
• an output port in the discharge head.
