A drying apparatus includes a dryer for a textile web. The dryer includes a drying chamber and at least one air-permeable drum arranged to rotate in the drying chamber. The textile web is guidable over a partial section of the circumference of the drum and heated drying air is flowable through the textile web. The dryer further includes a device to introduce heat for heating up the drying air. The device includes an internal hot gas source and an external hot gas source. The internal hot gas source is a component of the dryer and the external hot gas source is arranged peripherally to the dryer and includes a hot gas line connected at least indirectly to the dryer.

A process for combusting a high-moisture fuel to generate steam in which the high-moisture solid fuel is first dried by contacting with an oxygen-depleted gas stream while being heated by indirect heat exchange with a recirculating thermal fluid. The dried fuel is then combusted with a combustion air stream to produce a combustion products stream whose heat first is used to generate steam, and then to preheat the combustion air stream by indirect heat exchange in which a portion of the combustion air stream and/or a portion of the combustion products stream bypasses the heat exchanger. The combustion products stream also provides heat to dry the solid fuel via the recirculating thermal fluid.

The present disclosure relates to a towel maintenance device for storing and keeping a towel and for heating and drying the towel stored and kept therein. The towel maintenance device—provides a structure in which heated air flows in a first staying space formed in a heat transfer plate and heats the heat transfer plate, thereby allowing a textile product such as a towel and the like in contact with the heat transfer plate to be heated based on thermal conduction, and the heated air discharged through a communicating hole of the heat transfer plate is discharged while passing through the textile product such as a towel and the like or flows around the textile product such as a towel and the like, thereby allowing the product to be dried to be heated based on convection. The towel maintenance device according to the present disclosure enables entire objects to be dried to be rapidly heated and dried.

There is described here a method of desiccation of aerobic granules.

In order to be able to operate a dust separator with or without a lower closure element (44), the closure element (44) is part of a separate closure unit (40) which is mounted under the dust separator if required. For this purpose, the dust separator, the closure unit (40) and optionally further components, such as a delivery flow generator, are kept available in a kit so as to be able to assemble the treatment unit as required. The dust separator can be operated in batches by means of the closure element (44).

The present invention provides a drying method to dry a to-be-dried object by allowing the to-be-dried object to contact with gas having a different temperature. The method includes comprising: an introduction process of introducing the to-be-dried object; a first heating/cooling process of heating or cooling the to-be-dried object to have a first temperature; a transportation process of transporting the heated or cooled to-be-dried object; a humidity comparison process of comparing the to-be-dried object humidity of the to-be-dried object with the gas humidity of gas used for dehumidification; an atmosphere temperature adjustment process of adjusting, when the to-be-dried object humidity is high, the temperature of the gas used for dehumidification to a second temperature lower than the first temperature and adjusting, when the gas humidity is high, the temperature of the gas used for dehumidification to the second temperature higher than the first temperature; a dehumidification process of allowing the to-be-dried object to contact with the gas of the second temperature to thereby dehumidify the to-be-dried object; and a removal process of removing the to-be-dried object.

A method and a machine for drying blood smears and an automatic smearing device are provided. In the method, a dry gas is used as a drying medium to dry a blood film on a blood smear in drying the blood smear, thus reducing drying time and the number of blood smears which are dried together. The dry gas is obtained by: first, removing a liquid from a pressurized gas, second, filtering a vapor, and finally, decompressing the dried pressurized gas to be a non-pressurized gas having lower humidity. In addition, the dry gas is further heated for further reducing the humidity of the dry gas. In order to prevent cell distortion from occurring, the heated dry gas is caused to gently flow over the blood smear in a direction which the blood film is spread.
