Embodiments provide a multi-pass kiln with two or more chambers, an entrance and an exit at a proximal end of the kiln, and a reciprocal flow path extending through the kiln from the entrance to the exit. Lumber charges traveling along the reciprocal flow path may travel in a first direction along one side of the heated second chamber before traveling in a substantially opposite second direction along the opposite side of the second chamber. The distal end of the kiln may be substantially sealed, and a pressure differential between the distal end and the proximal end may draw moist heated air from the heated chamber toward the exit and entry to preheat and/or condition lumber charges traveling through the first chamber.

A system for drying wet food articles (such as produce) is disclosed herein. The system can comprise a turntable capable of rotating multiple barrel stations. The system can comprise various loading, drying, dumping, and cleaning positions, and the barrel stations can be rotated to each of these positions. The present disclosure also describes various methods for drying wet food articles utilizing such systems.

A biomass-derived protein compound has a high concentration of protein and can be made to have a very low concentration of fat and water; even when the biomass feedstock has a high fat concentration. The biomass-derived protein compound may be a whole protein that is non-denatured and enzymatically digestible. This unique protein compound can be produced from molecules from more than one source organism, including various animals and/or plant feedstocks. The unique protein compound is derived from a unique biomass method and apparatus for the treatment of a biomass stream to extract and separate an essentially solvent-free product from the biomass stream. In this unique method the solids content of the biomass stream is increased by bringing the biomass stream into contact with a moderately pressurized liquefied gas solvent, to create a high solids content biomass stream and introducing the high solids content biomass stream to an extraction apparatus.

An apparatus and method for cooking, heating, or drying in which, as items or materials are conveyed through a heating chamber by a linear, spiral, or other type of conveyor, hot combustion product gases are delivered upwardly through an upwardly extending first annulus or other flow gap which is closest to the conveyor. The hot combustion product gases are then delivered downwardly through the heating chamber into contact with the items or materials on the conveyor. Next the combustion product gases are delivered from the lower portion of the heating chamber into the lower portion of a second annulus or other flow gap or passage. The second flow gap or passage is separated from the heating chamber by the first annulus or other flow gap. Subsequently, the combustion product gases are delivered upwardly through the second flow gap or passage.
