VIBRATION DRYER WITH SPIRAL CHUTES Russian patent published in 2008 - IPC F26B17/26 

FIELD: drying engineering.

SUBSTANCE: vibration dryer comprises charging device for damp material, device for discharging, drying chamber, and vibrator. The drying chamber is made of a housing that is connected with the bearing plate via a flexible suspension. The heating steam is supplied to the chutes from above, and the condensate is removed from bellow. The drier has sectional locators that receives chutes, heating pipes that are mounted in the heating chamber, and cyclone connected with the device for discharging. The heat is supplied to the material from the heating pipes. The locators are mounted within a heat-insulating sectional casing connected with the housing. The top section of the housing receives the dust deflector. The hopper for collecting the dust is interposed between the spirals in the central part of the housing. The vibrator has driving shaft connected with the electric drive. The outlet of the dust deflector is provided with acoustical plant for trapping moderately dispersed particles and is connected with the cyclone.

EFFECT: enhanced efficiency of drying.
