FILTERING ELEMENT FOR AIR CLEANING FROM FLOUR DUST IN LINES OF FLOUR SUPPLY TO DOUGH-PREPARATION DEVICE Russian patent published in 2013 - IPC D03D15/00 B01D39/08 

FIELD: textile, paper.

SUBSTANCE: filtering element for air cleaning from flour dust in lines of flour supply to a dough-preparation device, the main material of which is a filtering cloth, made by twill weave of warp and weft threads. The cloth is made of polyamide complex threads with linear density of 93.5 tex (g/km), providing for smooth surface. Current-conducting threads are added into the cloth structure along the warp in the amount of 1.5-2.0%. The surface density of the cloth makes 400±40 g/m², thickness - not more than 950 mcm, air impermeability - 260±40 dm³/m².s, and level of specific resistance - not more than 10⁴-10⁵ Ohm.

EFFECT: using a filtering element with the proposed filtering cloth improves quality of filtering, reduces level of specific electric resistance.
