ABSTRACT:
An apparatus for producing dried and dehumidified cooling air for bulk stored grains and other produce from which moisture evaporates comprising a multiplicity of narrow elongate beds 2 of desiccant between which a multiplicity of heat exchange channels 3 providing heat exchange surfaces 4 in contact with each bed 2 of desiccant are provided. Air to be treated is passed through the beds 2 of desiccant while secondary air is forced through the heat exchange channels 3 to cool and remove the heat of sorption collected by the desiccant from the air being treated. desiccant can be regenerated by passing heated air through the beds.
