An end gate cleanout apparatus which includes a plurality of slidable trays that can be connected end to end and moved into the bottom of a grain dryer or other apparatus and including driving means for removing or inserting such removable troughs so as to allow material to fall from the dryer.

End gate positive cleanout

An annunciator readout unit for continuously monitoring and indicating to an operator of a machine such as a grain dryer, the condition and stage of the grain drying process and further including warnings and unusual conditions including a grid structure surrounding a plurality of indicating lights with sealing material between the backing plate and the grid structure and further including composite layers of masks, opaque sheets, a thick clear plastic sheet and a top indicating sheet including a mask portion mating with the grid structure and including clear and colored panels overlying the various indicator lights with printed material formed thereon and wherein due to the structure of the composite sheets light from a particular light source does not fringe into adjacent chambers.

Annunciator readout unit

A grain dryer is disclosed in which a blower forces air past a burner and then through a duct into a bin made of oppositely curved columns of grain defining between them and an end wall a plenum chamber for drying the grain in the bin. The invention resides in the use of a plurality of spaced baffles of particular configuration designed to take a stream of air of non-uniform pressure and temperature over a cross section of the stream, and transforming said stream into a stream in the plenum chamber of substantially uniform pressure and temperature over any cross section thereof, said stream, if desired, having a predetermined temperature gradient lengthwise of the bin which compensates for a lengthwise dryness gradient in the grain in the bin.
