Systems and methods in accordance with the present invention provide for the efficient distillation of ethanol in an ethanol plant including a beer column. Heat is captured in the distillation process and utilized to drive operations in the ethanol plant.

A continuous feed lyophilizer drying chamber that has an overall internal volume, a primly drying stage portion having a primary drying stage internal volume, a secondary drying stage portion having an internal volume, a frozen formulation feed inlet that provides frozen formulation droplets into the internal volume of the primary drying stage of the drying chamber and a dried particle outlet proximate an end of the continuous feed lyophilizer drying chamber configured to provide dried formulation droplet particles. The primary drying stage typically makes up from about 65-75% of the overall internal volume of the drying chamber and the secondary drying stage makes up from 25 to 35% of the overall internal volume of the drying chamber. The drying chamber dries frozen formulation droplets received into the primary drying stage internal volume via the frozen formulation feed inlet.

The device for drying or heating and cooling bulk material in accordance with the invention consists of a rotatable drum comprising means for receiving the bulk material in a first region and means for discharging the bulk material from a second region, wherein a central region is arranged between the first and second regions, said central region consisting of an annular structure with a first and a second diaphragm with central diaphragm apertures each, which form substantially two diaphragm planes parallel to each other, and comprise a plurality of transport channels closed toward the central region for transporting the bulk material from the first region to the second region of the rotatable drum through the central region, wherein the transport channels extend from the first to the second diaphragms at a non-90 angle relative to the two diaphragm planes.

The invention discloses a straw brick dehumidifying and drying device, which includes a machine body, wherein a molding cavity is provided in the body, a sealing device is provided on the front side of the molding cavity, the sealing device includes a sealing plate, and the rotating device There is a rotating shaft, and a rotating wheel is fixed on the rotating shaft. Seven groups of storage devices are arranged on the outer periphery of the rotating wheel with the rotating shaft as the center. The storage device can place straw bricks. The rotatable rotating wheel drives the straw brick to rotate slowly, and the placement direction of the straw brick is always upward to maintain the stability of its placement. Secondly, the hot air is blown to the molding cavity through the rotation of the fan blades, and the hot air can be converted by the condensation device. It is discharged in a liquid state, and has the function of dehumidifying the molding cavity, thereby keeping the air in the molding cavity dry and improving the efficiency of preparing straw bricks.

A single pass, multiple stage, rotary drum heat exchange dryer (22) is provided for drying products such as distillers grains and includes a tubular shell (64) with a moist product inlet (66), an opposed dried product outlet (70), and an internal drying chamber (78). The chamber (78) includes a convection drying first stage (80), and conductive drying final curing stage (82) an intermediate stage (84); the intermediate stage (84) is subdivided into a plurality of contiguous drying zones (86-92). The zones (86-92) include individual flighting assemblies (164) which are of substantially the same density and heat transfer ratios.

A rotary drum dryer includes a shell, an apertured rotary drum disposed within the shell and positioned to define a plenum between an interior surface of the shell and an exterior surface of the rotary drum, the plenum being divided into a plurality of zones by at least one separator plate disposed in the shell, and a plurality of drying air inlet nozzles disposed along the shell, each of the plurality of drying air inlet nozzles being positioned to direct drying air into a corresponding one of the plurality of zones.

A method for drying bulk goods, in particular wood fibers and/or wood chips, wherein the bulk goods is continuously dried in a dryer (1), in particular a drum dryer. The vapor-gas mixture flows through the drum dryer (1) in a dryer circuit and is indirectly heated via at least one heat exchanger (4) by a burner waste gas that is heated in at least one burner (5). The drying vapors are supplied to the at least one heat exchanger (4). Upstream, downstream and/or within the at least one heat exchanger (4), at least a partial flow of the drying vapors are branched off to be conducted into the burner (5). The remaining partial flow is conducted to the dryer (1) again. The partial flow of drying vapors to the burner (5) is driven by at least one regulable partial vapor fan (10).

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 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 seed drying system for positioning a manifold in a seed treater includes a seed treater that contains a plurality of seeds that have been coated with a liquid treatment. A manifold is positioned within the seed treater and a fan is provided to selectively urge air. The fan is fluidly coupled to the manifold to direct the air over the seeds thereby facilitating the liquid treatment to dry on the seeds. A mounting unit is provided and the manifold is coupled to the mounting unit such that the mounting unit retains the manifold in a horizontal orientation. The mounting unit is releasably coupled to the housing such that the manifold is retained in the drum. Moreover, the mounting unit centrally positions the manifold in the aperture.
