Abstract: A drier for drying boards comprises at least one conduit for directing airflow towards one of the faces of the board. The drier is configured such that at least a portion of the airflow travels across the face of the board along the longitudinal axis of the drier, the longitudinal axis of the drier being the axis along which the board travels as it is dried.

Abstract: A dryer for drying objects of material has a container-like body. The body is substantially tight and material to be dried can be fed into it. The body may be substantially upright or inclined. The material to be dried is fed at the lower part of the body is discharged from the upper part thereof and drying gas is directed to the dryer substantially at the upper part of the body and taken off from the lower part thereof. This is achieved by shut-off arrangements of the feeding and discharge of the material to be dried and by the structure of the body. The drying gas circulates in the dryer in a substantially closed circulation. The drying gas taken off from the lower part of the body is heated by element of a heating device and the heated drying gas is fed to the upper part of the body.

Abstract: A drier for drying wet material includes a drying chamber receiving material to be dried. Heating fluid is flowed generally overall concurrently with the material through at least a portion of the chamber and drying fluid is flowed generally overall countercurrently relative to the material through at least part of the chamber.

Abstract: The present invention refers to a process for drying solid organic substances in aqueous phase including the steps of: feeding a continuous flow of such organic substances having a water content=50% by weight into a turbodrier having a cylindrical tubular body with horizontal axis, equipped with inlet and outlet openings, a heating jacket for bring the inner wall of the tubular body to a predetermined temperature, a bladed rotor extending inside the cylindrical tubular body (1) where it is made to rotate at speeds between 15 and 40 m/s, so as to disperse the continuous flow of organic substances into a flow of particles of organic substances; centrifuging the particles of organic substances against the inner wall of the turbodrier heated to a temperature above 130° C.

Abstract: A drier for drying wet material includes a drying chamber with a plurality of heating region regions and a plurality of drying regions, alternatively located along the path of the material through the drier. Each of the heating regions is heated with heating fluid by a heating recirculation system wherein the heating fluid overall flows in heat exchange with the material in the chamber, but wherein the heating fluid can flow in various ways within each heating region. A fluid circulation system flows drying fluid through each of the drying regions generally in countercurrent flow relative to the flow of material through the drier, although the drying fluid can flow in various ways within each drying region. The drying fluid exiting the drier is used to preheat the heating fluid exiting the drier prior to the heating fluid reentering the drier. Makeup heat is supplied to the system.

Abstract: A system and method for drying particulate material in a dual flow hopper employs multiple flow paths by which heated gas is inserted into the hopper at different levels. Gas is extracted from the hopper and is divided for flow along two flow paths, one of the flow paths receiving gas that has been dried and the other flow path receiving gas that has not been dried.

Abstract: Instead of desiccating articles of clothing by spinning the articles, the method and apparatus according to the invention removes moisture from these articles by pressing or drying them with the aid of hot air. Desiccation of the clothing articles occurs gently and with a low expenditure of energy by subjecting the articles to the action of at least one gas jet and, in particular, of a compressed air jet, which is not aligned parallel to the surface of the article of clothing to exert a force upon the article. Advantageously, the article of clothing is subjected to the action of gas jets on both sides.

Abstract: A method and apparatus for impingement of fluid onto a moving surface. The apparatus includes an asymmetric slot nozzle having an opening formed between an upstream wall and a downstream wall. The nozzle is disposed generally adjacent the surface onto which the fluid is to be impinged forming an impingement distance between each of the walls of the nozzle and the surface. The impingement distance of the upstream wall is greater than the impingement distance of the downstream wall such that at least a portion of the fluid is delivered through the nozzle in a direction that is counter to the machine direction.

Abstract: The drying assembly includes a drying apparatus with a far-infrared-ray radiator and ultraviolet irradiator. This ultraviolet irradiator is provided in the rear of the drying apparatus and the irradiation amount irradiated from the device is about 300 to about 600 mJs/cm2.

Abstract: A method and apparatus for coating and drying coated substrates without introducing significant surface imperfections while running at higher web speeds than known drying methods. The substrate is preferably coated within the drying enclosure or the coating bead may form a closure at the entrance of the drying enclosure. The substrate is moved through a first drying enclosure along a first axis. The first drying enclosure is substantially isolated from an external environment. A first low velocity, substantially laminar flow field of a drying gas is directed across the front surface of the substrate. The first flow field is generally parallel to the front surface and generally perpendicular to the first axis to minimize the formation of surface imperfections during the evaporation of the coating solvent. The substrate may then be moved to subsequent drying enclosures through transition enclosures that minimize surface imperfections due to high velocity interaction between the adjacent drying enclosures.

Abstract: In order to dry boards, the boards are guided on racks through a drier and brought into contact with drying air in two stages. In a stage A with a higher drying power, the drying air is supplied at a higher temperature and with an at least average humidity, and in the other stage B, it is supplied at an average temperature and with a low humidity. The waste heat of the outgoing air from stage A is used for preheating the drying air. This process should reduce the consumption of primary energy. For that purpose, a process is known that consists of also using the outgoing air condensation heat. This has the inconvenience, however, of requiring substantially more secondary energy, as important air mass flows are required to transfer heat because of the low condensation temperature. Primary energy should be reduced by using condensation heat without substantially increasing secondary energy requirements.
