The softgel drying machine comprises a casing, an air channel, a drying chamber, an air return channel, a tumbler and an air-drying system. The casing comprises an air circulation chamber and an air generation chamber. The drying chamber comprises at least one air supply opening and at least one air returning plate. The air-drying system comprises at least one air blower fan, a dehumidification module and an air return cooling module. The air blower fan comprises an air blower inlet port, an air blower outlet port, a chiller and an air supply duct. The chiller is coupled to the air blower outlet port. The air return cooling module comprises an air return duct, an air return inlet port and an air return outlet port. The air return inlet port is airtightly coupled to the air return channel through the air return duct.

An apparatus and a method is provided for continuously drying bulk goods, in particular wood fibers and/or wood chips, in a dryer, wherein the drying vapors are led to a dryer circuit, in which the drying vapors are indirectly heated via a heat-exchanger and are conducted to the dryer again.

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.

An air drying unit for compressed air systems is provided. The air drying unit has a precooler/reheater, a main cooler and a moisture separator. Incoming air is cooled to cause moisture within the compressed air to condense, which is then separated to dry the compressed air. The precooler/reheater, main cooler and moisture separator are designed as an integral unit that does not require pipes to connect the components together. Instead, compressed air flows through the sealed unit through passages therein between the precooler/reheater, main cooler and moisture separator.

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.

There is described here a method of desiccation of aerobic granules.

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 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.
