An apparatus for drying material for an asphalt mixing facility includes a rotary kiln rotatably drivable about an axis of rotation, in which the material is dried, wherein the rotary kiln has a material inlet and a material outlet, a heating unit coupled to the rotary kiln for feeding heat to the rotary kiln, wherein the heating unit is designed with a burner which has a burner housing having a longitudinal axis, an air duct arranged at the burner housing for feeding air, a swirling element for swirling the air in the burner housing relative to the longitudinal axis, a hydrogen gas line connected to the burner for feeding hydrogen gas into the burner, wherein a hydrogen gas nozzle is connected to the hydrogen gas line for discharging the hydrogen gas, a burner head arranged at the burner housing for generating a burner flame.

The dryer comprises a dryer receptacle having an inner space for receiving herbaceous material and a driving device for rotating the dryer receptacle about a rotation axis of the dryer receptacle. Vanes for engaging herbaceous material received in the inner space of the dryer receptacle extend from an inner surface of the dryer receptacle into the inner space of the dryer receptacle. In a cross-section with a sectional plane perpendicular to the rotation axis, the vanes are inclined with respect to the radial direction. Vane heating elements are incorporated into the vanes.

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.

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 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.

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

The continuous process of the present invention is intended to obtain dry biomass from two treatment steps by drying organic waste. The waste previously sieved and crushed waste are dumped into a first dryer, inside of which temperatures are between 280° C. and 300° C. at the inlet thereof and between 90° C. and 100° C. at the outlet, then passing to a conveyor belt where at room temperature a partial cool-down occurs and the waste is dumped into a second dryer inside of which the temperatures are between 180° C. and 200° C. at the inlet and between 75° C. and 85° C. at the exit, completing the process, during which the interior of the dryers is maintained in negative pressure through exhaust flow and the oxygen content is kept between 5 and 7%.

A magnetic field thermal generator has one or more heat elements comprised of rotating pipes placed so they travel across the magnetic field generated by the magnetic field chamber, with said magnetic field being generated by either permanent magnets or electromagnets. The relative motion of the heat element to the magnetic flux from the magnetic field magnets results in heat generation, as well as in the generation of Oxyhydrogen (HHO). An optional hydrogen separator may be used to separate the HHO into the Hydrogen and Oxygen components.

A dryer adapted for use in an asphalt plant. The dryer includes a drum having an inner wall and a flight having a proximal end connecting the flight to the inner wall of the drum and a distal end that is spaced apart from the proximal end. A first profile extends from the proximal end to the distal end of the flight and defines a flight shape. A notch is formed in the distal end of the flight, which notch includes a notch shape that is defined by a second profile. The second profile has a length L, a center point, and a portion that substantially approximates a conic section.
