Drying and cooling device and technology for damp and hot imported barley leftovers

The invention relates to a drying and cooling device and technology for damp and hot imported barley leftovers. The device comprises a vertical thermal insulation container, an airflow filter device and a centrifugal fan, wherein a raking distributor, hot air branch pipes and a turning plate discharging mechanism are arranged in the vertical thermal insulation container, a feeding inlet, a material level sensor, a hot air inlet and a cold air inlet are sequentially formed in the wall of the vertical thermal insulation container from top to bottom, the airflow filter device is arranged right above the vertical thermal insulation container, light barley bran, dust and the like carried by airflow are blocked on the outer surface of a filter bag and shaken off under pulse jetting of circulating compressed air to fall into the vertical thermal insulation container, wet airflow is cooled in an air channel and the fan to separate out part of condensed water and then is discharged into atmosphere, and the airflow pen
