Abstract: A method for drying photographic materials from an initial moisture content to a desired final moisture content is provided. At least one side of a photographic material having an initial moisture content is heated, with a first heater stage, to achieve an intermediate moisture content in the material. The intermediate moisture content is less than the initial moisture content of the material and greater than the desired final moisture content. The intermediate moisture content of the material is measured and an output signal corresponding to the intermediate moisture content is provided to a control means. The material is then heated with a second heater stage to the desired final moisture content. The second stage heating is controlled using the output signal and the desired final moisture content.

Abstract: A technique is disclosed for drying and curing a liquid film applied to a former which is reactive to radio frequency energy so as to generate heat. A liquid film, such as latex, is applied to a metallic former which is then disposed in the proximity of an applicator which propagates radio frequency energy. In response, by a process of induction the former generates heat and thereby advantageously dries said film in an inside-to-outside manner. A superior product is produced which is substantially free of defects and blemishes.

Abstract: A drying method and a device each employ a specific range of infrared radiation which has a high transmissivity relative to a coated layer formed on a metal substrate and a high absorptivity relative to the substrate. The energy transmitted through the coated layer is absorbed in the substrate and changed into heating energy to heat the substrate surface. The backsurface of the coated layer is also heated and solidified. The surface of the coated layer is solidified at the termination of the drying process so that surface is not injured by evaporation of solvent from the coated layer. A combination of infrared radiation and a blow of hot air ensures that the coated layer will not experience irregular heating which helps to prevent the generation of pin holes in the coated layer and shortens the drying period. The blowing direction is oriented in the same or at right angles to the infrared radiation.

Abstract: A device for drying articles such as semiconductor wafers comprising a vacuum process chamber for holding articles to be dried; a vapor generator substantially isolated from the process chamber for supplying a substance such as isopropyl alcohol in vapor form to the process chamber; a heater for heating the walls of the process chamber to discourage the substance vapor from condensing on the inside walls of the process chamber. The device can also be used for rinsing and cleansing articles prior to drying.

Abstract: A fabric drying system has an exterior housing and a rotating chamber for containing fabric laden with moisture that is to be dried and uses a combination of microwave energy and an auxiliary convection air heater to heat and vaporize the moisture and expel it with exhaust air so as to dry the fabric. In addition, the fabric drying system employs energy efficiency devices that permit the system to dry the fabric using the least amount of energy. Heat energy from the exhaust air is transferred to the intake in a heat exchanger. Additionally, heat energy from the exhaust air is used by recirculating a portion of the exhaust air and mixing it with the intake air before the air is introduced into the fabric drying chamber. The system also provides for sensors that detect the temperature and/or humidity of the exhaust and the intake air.

Abstract: An embodiment of the present invention includes an open-ended, non-spinning housing, which is fitted with an inner lining that rotates within the housing at speeds sufficient to de-water material loaded from within and along the length of the inner liner. A loading conveyor system has a discharge end that can be relatively positioned horizontally at various depths within the inner liner to deposit product at continuously variable layer depths on the inner liner while it is spinning. Once loaded, the inner liner is accelerated to a drying speed and the housing is swiveled to vertical on gudgeons. Once drying is complete, the inner liner is slowed down, or stopped, and the de-watered product can fall out to land on an unloading conveyor.

Abstract: An apparatus for drying a web of roll material has two rows of comparatively low and high temperature cylinders, and a metal belt and a felt belt entrained in parallel for transporting the web on a serpentine path around the cylinders. The metal belt is pre-heated at an input side to each low temperature cylinder to a temperature from 140.degree. C. to 170.degree. C. An input press roll applies a nip pressure to the metal belt against the web, felt belt, and low temperature cylinder from 60 to 200 pli (pounds per linear inch). The surface of the low temperature cylinder is heated to an intermediate temperature from 100.degree. C. to 140.degree. C. The temperature of the heated belt at an input side is maintained only about 20.degree. C. higher than that of the low temperature cylinder. The low temperature cylinder has air pressure grooves for maintaining a negative air pressure in the range of 0.1 to 0.7 bar at its surface for lowering the vapor pressure for water evaporated from the web.
