A drying apparatus includes a drying furnace which a medium to be conveyed enters, a heater configured to heat the medium in the drying furnace, an exhaust section configured to exhaust air from the drying furnace, and a movable section configured to move, wherein an intake port through which air flows from an outside of the drying furnace into the drying furnace opens in the drying furnace, the exhaust section includes a duct extending from the drying furnace and a fan configured to exhaust the air from an inside of the drying furnace toward the outside of the drying furnace through the duct, and the movable section moves to thereby adjust at least one of an intake volume of the air inflowing through the intake port and an exhaust volume of the air discharged from the drying furnace.

A decompression drying device includes, in addition to a conventional release valve for introducing external air to restore the inside of a drying chamber to a normal pressure after drying has been completed, a separate external air introduction means for introducing external air into the drying chamber when the pressure inside the drying chamber has reached near a target pressure during a decompression drying process. The decompression drying device is used for drying a pharmaceutical product and, in particular, is used for manufacturing a botulinum toxin dried cake. By introducing external air while finely adjusting its inflow amount when the pressure inside the drying chamber reaches near the target pressure during the decompression drying process, it is possible to prevent a phenomenon in which the pressure inside the drying chamber, particularly the pressure around a vial containing a liquid sample, rises and decreases significantly.

A method and a device for monitoring the energy management of dryer systems for plastic granules as well as a method and a device for drying plastic granules. Both the energy input and the energy requirement are continuously determined so that operation of the corresponding systems is optimized both in terms of product quality and energy consumption.

A dryer for ceramic products, such as for example slabs or tiles, comprising: a drying chamber (1): at least one drying channel (10), comprising a shelf (11) for one or more ceramic products: at least two manifolds (20), positioned respectively above and below the shelf (11), each of which is connected to a source of conditioned air. The manifold (20) located above the shelf (11) has an extended shape and is provided with a flat lower surface (21a), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of lower openings (22a) for emitting the conditioned air into the drying channel (10). The manifold (20) located below the shelf (11) has an extended shape and is provided with a flat upper surface (21 b), which in the plan view covers at least a portion of the shelf (11) and is provided with a plurality of upper openings (22b) for emitting the conditioned air into the drying channel (10).

A facility for processing CO2 from a high-output CO2 source includes at least one CO2 distribution system having a supply circuit comprising an inlet end connected to the high-output CO2 source for collecting and storing the CO2, and an outlet end; drying means for drying in a CO2 atmosphere, connected to the CO2 distribution system, and configured to process said CO2 thus distributed during a drying operation and comprising storage means connected on the one hand to the outlet end of the supply circuit and on the other hand to the drying means, said storage means being configured to temporarily store the CO2 from the high-output CO2 source for later processing of said CO2.
