DEVICE FOR GAS DISTRIBUTION IN MINE GRAIN DRYER Russian patent published in 2012 - IPC F26B17/12 

FIELD: heating.

SUBSTANCE: device is designed for convective drying of disperse materials, for example grain, in dense layer, and can be used in agricultural and other industries. Device includes drying 1, supply 2 and discharge 3 chambers, as well as distributing ducts 4, 5 (mainly in the form of pentagon) and semi-duct 6, which are located in drying chamber so that supply duct 4 of each row alternates with discharge 5 duct; at that, open end surface 7 of supply ducts is connected to supply chamber 2, and discharge 5 ducts are connected to discharge chamber 3 located on opposite side of drying chamber 1. Vertical side walls 10 of ducts 4, 5 and semi-ducts 6 are uniformly perforated throughout their length and bent outwards through the distance providing the equality of average values of gas consumptions along them.

EFFECT: invention allows improving the uniform gas distribution along ducts of drying chamber, improving the drying quality and increasing the drying equipment efficiency.
