Abstract: The apparatus has a container which contains a first filter. During operation, this separates the first interior region containing particulate material from a second interior region. The latter is connected to a downstream dust separator. This has a housing which contains a second filter. The apparatus furthermore has a fan, at least one dust concentration sensor and a control device connected to this and to the fan. During fluidization and treatment of the particulate material in the first interior region of the container, the dust concentration in the oxygen-containing gas flowing from the first filter to the second filter and usually consisting of air is measured. If the dust concentration is at least equal to a predetermined limit below the lower explosion limit, the control device switches off the fan. This makes it possible to keep the pressures generated by any dust explosion relatively small.

Abstract: A dryer with zone temperature controls for drying thick polymer-solvent layers on a substrate. The dryer is formed with several heating elements located in an air duct. The cool air is heated a specific amount as it passes each heating element. The heated air is then applied to the polymer-solvent solution on the substrate in a continuous fashion so that the polymer-solvent solution slowly heats up as it passes through the drying apparatus. The preferred design is to ensure a zone residence time of less than 10 seconds and a web heating rate of 10.degree. F./second or less. Most preferred design is a zone residence time less than 5 seconds and a heating rate less that 5.degree. F./second. The dryer is designed to have a continuous temperature gradient, especially in the critical later stages of drying when the solvent content of the film is less than 20%.
