A centrifugal pellet dryer is provided that includes a housing accommodating a rotor surrounded by a screen, and a feeding system for feeding a water-pellet-slurry to the rotor. The feeding system includes a pre-dewatering system for separating water from the water-pellet-slurry upstream of the rotor. The pre-dewatering system may include a feeding pipe having a dewatering perforation, with the pipe being configured to be mounted in different positions to adjust the amount of dewatering.

A system for preparing a container holding radioactive waste for dry storage. In one aspect, the invention can be a system for preparing a container having a cavity loaded with radioactive elements for dry storage, the system comprising: a gas circulation system comprising a condenser module, a desiccant module, and a gas circulator module; the gas circulation system configured to form a hermetically sealed closed-loop path when operably connected to the cavity of the container; and means for adding and removing the desiccant module as part of the hermetically sealed closed-loop path.

A suction device for drying at least one plastic strand, incorporates a suction housing having a top side, a bottom side and several lateral surfaces, the top side having an inlet opening and one of the other surfaces having an outlet opening for the flow of a drying medium therethrough, and a screening element which has through apertures a base area with a maximum length and a maximum width. Each through aperture has an aperture cross-sectional area, and the sum of the aperture cross-sectional areas of all through apertures together forms a total aperture cross-sectional area. The screening element is on the top side and has its drying area above the inlet opening of the suction housing. The at least one plastic strand is moved in a process direction on the screening element, wherein the process direction is in a longitudinal direction of the screening element. The length of the drying area is at least 150 mm, and a ratio of the total aperture cross-sectional area of the through apertures to the base area of the drying area is between 30% and 45%, in particular 35% and 40%.

A drying method and to a drying device (2) for a moist material web (4) which is composed of a textile fibrous material and which has for example been compacted using liquid jets (45). The drying device (2) includes a drying chamber (22) with an aeration (ventilating) device (29) and an inlet (18), an outlet (19) and a fluid-permeable conveying device (23) for the running material web (4). The material web (4) is transported within the drying chamber (22) by the conveying device (23) and is dried using a heated gas, in particular air. The drying device (2) additionally has a suction device (5) which locally suctions and discharges liquid, in particular water, which is contained in the material web (4) by a suction flow (6) at one or more suction locations (53) at the material web (4).

A foam drying apparatus is provided. The apparatus is configured to pass air, and in some cases heated and/or dried air, through a quantity of foam. This air passing through the foam absorbs or otherwise carries moisture out of the foam, drying it. The apparatus may utilize a pressure differential on opposite sides of the foam, causing air on the higher pressure side to pass through the foam. Typical applications may include the drying of foam assemblies which use water based adhesives to accelerate drying of the adhesive and/or removal of water from the foam assembly, and packaging of the foam assembly.
