The newly developed superheated steam dryer is based on the world renowned HDT. The HDT-FX retains the unique feature of combining expansion and drying in one unit. High filling power ...
In Steam Rotary Dryers steam is used as heating medium steam is conveyed inside a series of tubes. The heat transfer occurs from the tubes wall to the product by radiation and conduction even if the temperature of metal surfaces is generally low, as a result of the saturation temperature of steam which depends on its inlet pressure. Saturated steam is preferred type of medium, since heat is transferred to product by steam condensing and negligible effect is given by superheated steam.
The IBUS Superheated Steam Dryer combines the advantages of a rotary drum dryer with the advantages by drying with pressurized superheated steam. Both rotary drum dryers and pressurized superheated steam dryers are well- established technologies with a number of industrial applications.
The Superheated Steam Dryer SSD is a closed loop pneumatic conveying type dryer. The wet solids are fed into the flow of pressurized superheated transport steam by means of a pressure tight rotary valve, plug screw or similar. The Superheated Steam Processor SSP can be used for drying andor heat treatmentofmanyproducts.
by plants with high energy demand. Flue gas dryers such as the rotary and the most recently pneumatic and cyc-lonic dryers have been the favored technologies for dry-ing bagasse to a moisture content of 30 - 40 2-4. The fluid bed pressurized superheated steam dryer Fig-ure 1, which is successfully used to dry beet pulp, offers

Jan 30, 2018 The standard practice is to mix the superheated steam with cooling water in the desuperheater to produce saturated steam. In this paper, an investigation is made into the improvement of the cogeneration process by replacing desuperheater with superheated steam dryer.
The ecoDry destroys odors and meets emission guarantees by using a partially-closed circuit rotary dryer with integrated thermal oxidizer operating at over 1600F 870C. The basis of the ecoDry system is an indirect heated drying process using a partially-closed steam drying loop with process-integrated thermal oxidation.
A rotary dryer according to claim 1, in which there are provided means in the drying cylinder for superheating steam, means for injecting steam adjacent the superheating means, means for conveying steam leaving the injection means at one end of the drying cylinder to the superheating means, and ducting for conveying superheated steam from said ...

In the current paper, the drying of brown coal in a pilot scale superheated steam rotary dryer developed by Keith Engineering is investigated. It is illustrated that the dryer is able to significantly reduce the moisture content of Australian brown coals, with moisture reductions of up to ninety per cent achievable.
during the warm-up period of superheated steam drying. Moreover, the paper by Stroem 5 evaluates the drying behaviour of Brewers spent grain in a pilot-scale rotary superheated steam dryer. The evaluation is based on product moisture content, measurements of sticking and energy consumption.
