PROCEDURE FOR SEDIMENT DRYING AND DEVICE FOR REALISATION OF THIS PROCEDURE Russian patent published in 2011 - IPC F26B3/347 F26B7/00 F26B11/12 

FIELD: machine building.

SUBSTANCE: procedure for drying consists of several stages when pressure in leak-proof chamber is built to specified level by at least introduction of saturated steam and by maintaining this pressure during specified period of time. Sediment is loaded into a reservoir. The reservoir is positioned at a certain distance from internal walls of the chamber. Sediment is loaded with loading pressure maintaining devices. Superheated steam is introduced into sediment with a mixer. During operation the mixer is positioned near the wall of the reservoir most distanced from a micro-waves source. The mixer includes steam supplying facilities. When sediment is mixed, its central zone is heated with radiation of micro-waves of frequency from 400 to 2450 MHz in the direction of the reservoir. Water collected at condensation and pouring along walls of the chamber to the base of the chamber is removed by means of a valve leading outside. The device consists of the chamber including the leak-proof reservoir resistant to pressure and communicating with at least one generator of micro-waves through at least one orifice out of crystal quartz or any other material suitable for operation with micro-waves. The said chamber is communicated with the generator of saturated steam and with the input of sediment subjected to drying. The chamber is equipped with the mixer consisting of facilities for superheated steam supply. The facilities are arranged in the said chamber. The chamber has a door for dried sediment unloading.

EFFECT: optimised sediment drying without hazard of explosion; complete and fast sediment drying and reduced power consumption.
