A dryer adapted for use in an asphalt plant. The dryer comprises a drum having an inner wall and a plurality of flights, each of which is disposed on the inner wall of the drum and each of which has a proximal end and a distal end spaced apart from the proximal end. At least one of the plurality of flights comprises a V-shaped notch. A method for drying components of asphalt comprising drying the components of asphalt in the drum of such a dryer.

A dryer for a textile web includes a drying chamber having at least one air-permeable drum arranged in the drying chamber to rotate, wherein the drum includes an end face constituting an axially arranged suction side, the textile web is wrapable at least partially around the drum and heated drying air is flowable through the textile web. A hot gas source provides heated gas. A ventilator forms a suction draft via the suction side of the drum with drying air from inside of the drum and drying air that recirculates back into the drying chamber. At least one hot gas feeding ring encloses the suction draft and is configured to permit the hot gas from the hot gas source to flow essentially completely into the suction draft.

A method for controlling a garbage disposer that includes a crushing unit, a housing that includes an inlet port and an outlet port, a storage body, a communication hole, and an agitation unit is disclosed. The method includes the actions of connecting the communication hole with the inlet port by rotating the storage body. The method further includes opening the communication hole by rotating the agitation unit. The method further includes crushing, by the crushing unit, garbage. The method further includes supplying garbage to the inlet port. The method further includes closing the communication hole by rotating the agitation unit. The method further includes dehydrating garbage stored in the storage body by rotating the agitation unit and the storage body at a first rotation speed while maintaining the communication hole in a closed state.

A drum washing machine having an improved air circulation structure thereof. The drum washing machine includes a cabinet, a tub arranged within the cabinet, a drum rotatably arranged within the tub, a drying unit which heats and circulates air discharged from the tub so as to dry laundry within the drum, the drying unit including a drying duct equipped with a heater to heat air therein, a circulation passage provided such that air circulates between the tub and the inside of the drying duct, and a suction member which is coupled to one side of the drying duct and introduces air outside the tub onto the circulation passage, and a discharge member which is coupled to one side of the tub and discharges part of the air in the circulation passage to the outside of the cabinet.

A washing machine using an air discharge part disposed next to a detergent container to reduce humidity of the air flow exiting from the tub during a drying process. Both the air discharge part and the detergent container are contained in an accommodation part. The air discharge part can be maintained at a low temperature by washing water passing through the detergent container. The air discharge part includes rows of ribs on which water vapor in the air flow can condense due to the low temperature. The air discharge part is disposed on an opposite side of the washing machine to the electrical supplying component, thereby preventing water condensation on the electrical supplying component when the air flow is exhausted from the air discharge part.

An improved geometry for flights used in rotary drums of aggregate dryers in the manufacture of asphalt causes the aggregate to shower in an even veil across the full width of the drum under all loading conditions. An opening in the flight having a narrow bottom and wider top allows more aggregate to shower early, especially when flights are lightly loaded, on the uplift side of the drum to complete the aggregate veil and prevent hot gases from bypassing. The opening is oriented with its narrow bottom nearest the inner surface of the drum and its wider top farthest therefrom. The opening does not extend through the full height of the flight, which would form an undesired gap allowing an excessive volume of aggregate to flood out of fully loaded flights on the uplift side of rotation. Such flooding discharge causes a similar imbalance of drying to that caused by too little discharge from light loaded flights. The size and shape of the opening can be varied to adjust the amount of aggregate discharged from each flight to form the veil and to adjust the shape of the veil.

A rotary dryer for resin dehydration, comprising: a cylindrical body which rotates about an axis perpendicular to a diameter of the cylindrical body; an air filter located outside the cylindrical body; coils located outside the cylindrical body, wherein the coils are oriented vertically and oriented parallel to the diameter of the cylindrical body, wherein the coils do not comprise horizontal surfaces; and lifters located within the cylindrical body.

A cylindrical drum having a plurality of vanes which extend radially into the drum and extend axially substantially the length of the drum rotates about its axis such that the plurality of vanes convey vegetable material from a lowest point in the interior of the drum to a highest point in the interior of the drum, there, to drop the vegetable matter downward within the interior of the drum. A plenum feeds air through a nozzle opening in a rectangular slot extending in its longest dimension substantially the length of the drum. The plenum and nozzle being housed to form a Coand{hacek over (a)}-effect nozzle body having a tear-shaped housing. Two Coand{hacek over (a)} surfaces are situated in opposed relation terminating at the nozzle. The Coand{hacek over (a)} surfaces to guide air into a combined flow. A hopper plate cooperates with the housing to form a hopper directing vegetable matter to collide with the combined flow.

An exhaust quenching system is provided for use in connection with an asphalt concrete production plant having a dryer for drying aggregate material, an exhaust gas outlet conduit for discharge of exhaust gases from the dryer, and a dust collection assembly that is adapted to receive exhaust gases and entrained dust from the dryer via the exhaust gas outlet conduit. The exhaust quenching system is adapted to effect evaporative cooling of the exhaust gases in the exhaust gas outlet conduit upstream of the dust collection assembly.

A method of drying hemp plants using a rotary drying system that dries the plants without damaging the cannabidiol in the plants.
