A system for drying moist, particulate material includes a steam dryer having a container containing superheated steam. Upper and lower heat exchangers, with a channel extending through them, are located in the container. An impeller generates a flow of steam upward in the container outside the heat exchangers and downward through the channel. Guide plates around the heat exchangers guide the moist, particulate material from an inlet in the lower part of the container around the heat exchangers, subjecting the material to the flow of the steam, thereby drying the material. A steam conduit supplies a primary steam flow to the lower heat exchanger, which condenses the primary steam flow into a flow of hot water that is directed to a flow generator that generates a fluid flow from the hot water flow. A fluid conduit leads the fluid flow to the upper heat exchanger.

Disclosed is a slurry drying plant (1) comprising a slurry extruder (3) including a slurry inlet (2) and conveying means (4) arranged to convey the slurry through the slurry extruder (3) and force the slurry out of a plurality of exit openings (5) of the slurry extruder (3) to form a plurality of slurry strings (7), wherein the slurry strings (7) are forced out into a drying chamber (8) in which the plurality of slurry strings (7) is dried. The slurry drying plant (1) further comprises slurry heating means (6) comprising flow means for passing superheated steam past the slurry strings (7) in the drying chamber (8), and inlet pressure detection means (9) for detecting a slurry inlet pressure at the slurry inlet (2). The slurry drying plant (1) also comprises control means (17) arranged to control the conveying speed of the conveying means (4) in response to the slurry inlet pressure. Furthermore, a method for drying slurry and use of a slurry drying plant (1) is disclosed.

A shoe care device for processing shoes by air circulation includes an inner cabinet configured to accommodate shoes therein; a steam generator configured to supply steam into the inner cabinet; an inlet through which air is sucked from the inner cabinet; a nozzle installed inside the inner cabinet to be insertable into the shoe and configured to spray at least one of steam and air into the shoe; a connecting passage connected from the inlet to the nozzle; a blowing fan installed on the connecting passage to blow air from the inlet toward the nozzle; and a dehumidifying material installed on the connecting passage to dehumidify the blown air.

Serially connected heat exchange segments of a heat exchanger are stacked with ends of adjacent segments oriented oppositely. The segments have fixed pipes for heat exchange, pipe-riding shaftless auger flights for conveying feed material, and flanges for low-cost adjustment, removal and replacement of pipes and flights. Flights when arranged in arrays are arranged in pairs of counterrotating oppositely handed mutually cleaning flights. Rotary unions are unnecessary in this exchanger.

A dish dryer/warmer which is powered by steam that is exhausted from a steam kettle. A hollow inserts fits into a spout on the kettle and a hose connects the spout to the dish dryer. The steam is then funneled into the dish dryer. A set of holders inside the dish dryer are mechanically activated based on what, so that if a dish is placed into a holder then steam will be discharged directly into that holder, thereby warming the respective dish. A plurality of such holders can be present inside the dish dryer and each one is selectively activated to discharge steam when an object is placed inside a respective holder. All of the holders in the dish dryer share the same steam source (the kettle or other source).

The present invention relates to a method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof, which mainly consisting of a rotary steam tube dryer, a washing cooling tower, a coal mill, a 1st bag filter I, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. In the present invention, a drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.

The present invention relates to an apparatus for preventing, in a multi-stage dryer for drying coal using reheat steam, spontaneous ignition caused by oxidation of coal when coal is transferred to the multi-stage dryer from a fixed quantity coal supplier by way of a pulverizer. The present invention relates to an apparatus for drying coal using reheat steam, the apparatus being configured so that coal which has been dried primarily in a first coal dryer is inputted into a second coal dryer and thus is secondarily dried, wherein reheat steam generated from a reheater is supplied through a reheat steam supply pipe; a nitrogen supplier supplies nitrogen through a nitrogen supply pipe; saturated steam generated from a saturated steam generator is supplied through a saturated steam supply pipe; the reheat steam supply pipe, the nitrogen supplier, and the saturated steam supply pipe are connected to a 4-way valve; and the 4-way valve supplies nitrogen and saturated steam, or nitrogen or saturated steam, along with reheat steam, to first to fourth steam chambers through the steam supply pipe, and injects steam into coal which is transferred to a first transfer plate and a second transfer plate so that spontaneous ignition of coal is prevented in the course of drying and transferring coal.

A material drying plant using superheated steam includes a downwardly open chamber with an inlet for the material to be dried, an outlet for dried material to be dried, an inlet for superheated steam and an outlet for a vapour, a conveying system for introducing the material into the chamber, transporting the material in the chamber, during drying, and discharging the dried material from the chamber, a vapour compressor for compressing a first portion of the vapour recirculated from the chamber and a heat exchanger for transferring heat from the compressed first portion by condensing a volume flow of the compressed first portion supplied to the heat exchanger. A vapour atmosphere is formed in an upper region of the chamber, which vapour atmosphere floats on ambient air located in a lower region of the chamber, wherein a transition layer is formed between the upper region and the lower region.

A vacuum dryer not requiring a vacuum pump according to an embodiment of the present invention comprises: a drying chamber in which a drying rack is installed, and an exhaust valve communicating with the interior is provided on the outside of the other side; a steam generator located outside the drying chamber, having a water tank, and connected to a steam inlet; and a heat pump interlocked with the inside and outside of the drying chamber and configured by including a condenser provided in a high-temperature area, a first heat exchanger connected to the condenser outside the drying chamber, an evaporator provided in a low-temperature area, a second heat exchanger connected to the evaporator outside the drying chamber, a compressor connecting the first heat exchanger and the second heat exchanger, and an expansion valve connecting the condenser and the evaporator.
