A system for reducing moisture content of a wet waste product includes a drying surface; a dispenser that deposits the wet waste product onto the drying surface; an air moving device (AMD) that induces a flow of ambient air over the wet waste product on the drying surface to produce a dried waste product from the wet waste product; a collection area that transports the dried waste product away from the drying surface; and an agitator that moves the dried waste product from the drying surface to the collection area after the dried waste product has been dried to have a predetermined moisture content. A corresponding method for reducing moisture content of the wet waste product comprises using the system to convectively dry the wet waste product to produce the dry waste product. The wet waste product can be from a swine lagoon.

A dryer includes a dehumidification filter containing a temperature responsive material with an upper critical solution temperature, a fan sending gas through the dehumidification filter, a heater heating the dehumidification filter, and a controller controlling the fan and the heater and switching an operation mode of the fan and the heater between a drying mode and a regeneration mode, wherein, in the drying mode, an object to be dried is dried with the fan sending the gas through the dehumidification filter that is heated by the heater to temperature higher than or equal to the upper critical solution temperature, and in the regeneration mode, the dehumidification filter is regenerated with the fan sending the gas through the dehumidification filter at temperature lower than the upper critical solution temperature.

A low-energy drying system and method including a drying bed having at least four edges for holding the material to be dried, walls connected to the edges of the drying bed, a cover encompassing the drying bed and the wall, the cover having air permeable side walls, and air flow directors for directing air over the material in the drying bed.

Lumber drying kilns are provided that can include a ceiling member supported by opposing wall members and a pair of complimentary baffles extending vertically from about a junction of the wall and ceiling. Drying kilns are also provided that can include a junction between a wall and a ceiling above material to be dried within the drying kiln and at least one baffle extending vertically along the side of the material to be dried. Methods for retrofitting existing drying kilns are provided that can include extending vertical baffles from about a junction of a wall and ceiling of the drying kiln. Methods for drying material within a drying kiln are also provided that can include placing material to be dried within a drying kiln and drying the material within the kiln while a pair of vertical extending baffles hang along opposing walls of the kiln.

A drying system for drying an agriculture product is disclosed. The drying system includes an enclosure having one or more wall structures and defining a chamber for receiving and storing the agricultural product. Each wall structure includes an inner wall having a plurality of wood panels and an outer wall. Each wood panel is a treated wood panel and is adapted to absorb moisture from an air circulating inside the chamber. Each wood panel is treated with a solution of calcium chloride to enhance a moisture absorbing capacity. The outer wall is disposed substantially parallel and spaced apart from the inner wall and defines a gap therebetween. The enclosure further includes one or more moisture absorbing materials disposed inside the gap to absorb moisture received from the inner wall.
