A rotary vacuum drum drying system is described. The system may include a plurality of sensors and a control system operatively coupled with the plurality of sensors. The control system includes a processing device to receive, from the plurality of sensors, a plurality of parameters of the rotary vacuum drum drying system and transmit, to a client device, the plurality of parameters of the rotary vacuum drum drying system. The processing device is further to receive, from the client device, a message comprising an adjustment one or more parameters of the plurality of parameters and adjust the one or more parameters of the plurality of parameters based on the received message.

A smart oven includes a box body unit, a heating unit and a feed unit. The box body unit includes a box body that has a first inner wall surface, two second inner wall surfaces, two third inner wall surfaces, and a heating chamber having a chamber opening that faces downward. The heating unit includes a plurality of upper radiation heating lamps disposed above the chamber opening, and a plurality of outer radiation heating lamps disposed in proximity to the second and third inner wall surfaces. The feed unit includes a carrier platform that is movable relative to the box body between a material-placing position and a material-operating position, in which the carrier platform is distal from and closes the chamber opening, respectively.

An apparatus for a thermal treatment of a textile web includes at least one drum with a perforated casing surface around which a material web can be at least partially wrapped, at least one connecting element, and a patterning shell with a plurality of openings separated by ridges fitted onto the casing of the drum. The patterning shell includes at least two segments detachably connected with aid of the at least one connecting element. The at least one connecting element is arranged on or integrated into a ridge.

Embodiments provide a conveyor for conveying loads of lumber through a lumber kiln or other structure without the use of lumber carts or pushers. The conveyor may include a plurality of rollers arranged to form a flow path through the lumber kiln. Groups of the rollers may be driven by separate drives that are configured to rotate the rollers in opposite rotary directions and/or at variable speeds. Some or all of the drives may be operable independently of the other drives to transport loads of lumber at different speeds/directions in adjacent areas of the lumber kiln. In the event of a fire or a shut-down, the rollers in the proximal half of the kiln and those in the distal half of the kiln can be rotated in opposite directions to evacuate loads quickly from both ends.
