The invention discloses a material concurrent flow drying device and a process, which can be widely applied in the fields of chemical industry, coals, building materials, metallurgy and the like. The drying device consists of a housing wrapped with an insulating layer, and a feed hopper, a discharge hopper, a hot air inlet, a hot air outlet, a flow-guide block or a flow-guide strip and a flow-guide plate, which are arranged on the housing. The process mainly comprises the steps that: a material to be dried is fed to the device to meet with the hot air fed from the hot air inlet at once for heat exchange, water evaporation and hot air temperature reduction in the area provided with the flow-guide block or the flow-guide strip and then continues performing the heat exchange at material falls formed by the flow-guide plate till the material achieves the drying standard, wherein the material and the hot air leave the system from the bottom of the system and the whole device is in a negative pressure state.
