A process for the production of acetylated wood elements, a cooling system and a wood acetylation plant are described. A process for the production of acetylated wood elements comprises acetylating wood elements and cooling the acetylated wood elements wherein the cooling comprises supplying liquid water to the acetylated wood elements to provide wetted wood elements and exposing the wetted wood elements to a gas flow.

A dryer for ceramic products, such as for example slabs or tiles, comprising: a drying chamber (1); at least one drying channel (10), comprising a shelf (11) for one or more ceramic products; at least two manifolds (20), positioned respectively above and below the shelf (11), each of which is connected to a source of conditioned air. The manifold (20) located above the shelf (11) has an extended shape and is provided with a flat lower surface (21a), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of lower openings (22a) for emitting the conditioned air into the drying channel (10). The manifold (20) located below the shelf (11) has an extended shape and is provided with a flat upper surface (21b), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of upper openings (22b) for emitting the conditioned air into the drying channel (10).

A system and method for drying individual biomass units. Turbine exhaust heats ambient air to produce heated air, which passes through a conveyor system that carries a quantity of biomass product to an endpoint collection area. Heated air with fine product particles is ducted to a series of cyclonic particle separators and collected.

Embodiments provide a unidirectional multi-path kiln with two or more chambers and generally parallel flow paths extending through the kiln, on opposite sides, from charge entry portals at a first end of the kiln to charge exit portals at a second end of the kiln. Moist heated air flowing from the second heated chamber is received in the first chamber and circulated around the lumber charges with one or more fans. The lumber charges proceed in the same direction on the flow paths through the heated second chamber, which may be an existing kiln. Charge exit portals at the distal end of the kiln and/or intermediate charge portals between the second chamber and a third chamber may be provided with insulating members configured to reduce airflow from the second chamber through the charge exit portals.
