摘要:
Kiln design that uses a series of at least two subsections with airflow in constant but alternating directions instead of using bi-directional fans that periodically reverse directions. The uninterrupted alternating air flow may be used in continuous drying kilns (CDK) with two sets of carriages carrying spaced stacks of lumber travel in opposite directions through a sequence of chambers. The uninterrupted alternating air flow may be used with a set of at least one pathway for carriages carrying lumber to be dried where all carriages move from a first end of the kiln to a second end of the kiln.
摘要:
The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.

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.
摘要:
The present invention provides a water-based coating and/or coating system used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions as primer coats on substrates, and methods for applying the same to substrates. The method includes steps of applying a water-based paint to the interior surfaces of a substrate and drying the substrate by continuously forcing heated air onto the substrate as it moves through a drying chamber. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
摘要:
A method of painting a five-sided container, which includes applying a water-based paint to the interior surfaces and the exterior surfaces of the container, and forcing heated air into the open side of the container to at least partially dry the paint on the interior surfaces and the exterior surfaces of the container.
摘要:
In order to dry or ripen foodstuffs giving off humidity, a processing room (1) with air inlets (7) on its lower side is disclosed. The air inlets are formed by the peripheral openings of textile hoses (6) suspended above the surface of the floor (2). Aisles and/or traffic lanes (10, 11) are provided between the hoses (6).

Herein disclosed is an improved method of kiln drying architectural grade plywood and lumber which has been treated with a water borne agent. The improved method utilizes coated wire mesh as the kiln stickers. Use of the coated wire mesh stickers greatly reduces the incidence of sticker marks on the decorative faces of the plywood and lumber.
摘要:
A method of loading a plurality of formed ceramic products preparatory to baking thereof comprises positioning the products adjacent to one another in a plurality of superposed layers. The layers are formed in a plurality of successive loading steps, each of which is followed by a drying step operative to dry the uppermost layer, and to further dry previously formed underlying layers, to an extent sufficient to permit placement of a further layer on the uppermost layer without deformation of the uppermost layer or toppling of the stacked layers.
