  • Patent number: 8955957
    Abstract: Systems and methods for a dryer unit of a printer. In one embodiment, a dryer unit includes a light source having a plurality of lamps. The dryer unit further includes a controller that associates a target output power with each of the lamps of the light source. When in operation, the controller determines a speed of a printable medium that passes through the dryer unit. The controller is able to vary an intensity of light generated by the light source based on the speed of the printable medium by varying which of the lamps of the light source are energized to their target output power.

  • Publication number: 20100192792
    Abstract: A method of predicting at least one drying parameter for a printing press includes estimating an amount and type of an ink to be deposited on a printing surface, determining at least one of: i) a type of the printing surface, ii) a thickness of the printing surface, and iii) a speed of the printing surface moving through the printing press, and calculating, via a controller associated with the dryer, the at least one drying parameter based at least on: i) the amount and the type of the ink to be deposited on the printing surface; ii) the type of the printing surface, iii) the thickness of the printing surface, and iv) the speed of the printing surface moving through the printing press. Also disclosed herein is a method of determining if the ink established on the printing surface is dry.

  • Patent number: 6998021
    Abstract: In a paper machine which comprises process elements and a measuring beam, the measuring beam is arranged at least at one paper machine process element so that a measuring device for measuring quality properties of a paper web is arrangeable in the measuring beam. The paper machine process element is e.g. a blow box, which is arrangeable in a dryer unit of the paper machine between drying cylinders to blow air via at least one blow air channel provided in the blow box to guide the moving paper web and/or to assist drying.

  • Patent number: 6746163
    Abstract: A photographic processor and a dryer for drying photographic material. The dryer comprises a path through which the photographic material extends wherein at least one slack loop is provided in the photographic material. An adjustable roller is provided along the path to adjust a size of the slack loop and an air supply arrangement is adapted to provide drying air to the slack loop. The air supply arrangement supplies air to a frame member that has slots along at least one wall. A sliding member is provided within the frame member to open and close the slots in accordance with the size of the slack loop. This enables a supply of drying air directly on the media and further permits the automatic adjustment of the amount of air being supplied in accordance with the size of the slack loop or the length of the media being dried.

  • Patent number: 6705778
    Abstract: A photographic processing apparatus includes a photographic paper processing bath train. A drier, positioned downstream from the train, heats air and dries the photographic paper. Feeding racks feed the paper in a predetermined travel path which begins on an upstream side of the train, extends therethrough, and ends at the drier. A memory is accessed to estimate expected travel time t1 for passing of the paper through the travel path. The memory is accessed to estimate expected warmup time t2 for warming up the air in the drier to a target temperature T2. A controller compares the time t1 and the time t2, initially starts heating in the drier if the time t2 is longer than the time t1, and starts actuation of the feeding racks when a time difference (t2-t1) elapses after start of the heating to synchronize drier warmup to temperature T2 with paper reaching the drier.

  • Patent number: 6263589
    Abstract: The invention relates to a method of drying a fiber web and an arrangement in a fiber web drying apparatus, the fiber web being dried between two tight bands that move in parallel in the same direction and turn around turning rolls. The first band is heated and the second band is cooled. The fiber web is guided through a drying zone, defined by the bands, with at least one felt or wire, so that the fiber web comes into contact with the surface of the first, heated band and the felt or wire is between the fiber web and the second, cooled band. The position of the edge of the band is measured by means of a sliding block which is brought into contact with the edge of the band, the material of the sliding block being substantially harder than that of the band.

  • Patent number: 5383289
    Abstract: A drying system for drying textiles. The textile drying system includes an enclosed dryer having heating elements located therein, a feed system for continuously feeding textiles through the dryer, and a dehumidifier for directing conditioned air into the dryer. The textiles are dried in the dryer due to a combination of the heating elements located in the dryer and the conditioned air directed into the dryer by the dehumidifier. The dehumidifier conditions the ambient air to a selected temperature and relative humidity, and directs this air into the dryer. An exhaust port located in the dryer provides an opening for air within the dryer to exit to the atmosphere. The speed at which textiles are advanced through the dryer by the feed system is controlled by a moisture sensor which senses the moisture content of the textile goods exiting the dryer 12 and controls the speed of the feed system accordingly.

  • Patent number: 5377428
    Abstract: A drying control system and method for obtaining a substantially uniformly dried low moisture content web efficiently with reduced energy usage in a papermaking process is provided. The drying rate of the web in this process is precisely controlled by detecting and monitoring the web or felt low and high cross-direction temperature profiles and then actuating drying rate modulators as required to increase or decrease the drying rate to produce a substantially flat temperature profile in response to temperature profile information provided to an automatically or manually controlled central control system by web high temperature and low temperature sensors.

  • Patent number: 5341580
    Abstract: A method for drying wood strands and the like is shown and described. In a preferred embodiment, the strands are fed onto a conveyor which then moves the strands as a bed through a dryer housing. The housing may be partitioned into various zones and levels, depending on the desired configuration. A volume of drying air is heated and then passed through the bed of strands to reduce the moisture content of the strands. In a preferred embodiment, the strands are agitated to promote the even exposure of the strands to the drying heat. The strands are then conveyed through a conditioning zone before being discharged from the dryer housing.
