The utility model discloses a cabin hopper type efficient food material drying device with a two-way alternate cross flow function. The cabin hopper type efficient food material drying device comprises a heat supply device and a drying device, wherein a two-way direction conversion device is arranged between the heat supply device and the drying device, and comprises a box body, an executing mechanism, a linkage shaft, an upper circulation air pipe and a lower circulation air pipe, an upper circulation air valve and a lower circulation air valve are respectively arranged in the upper circulation air pipe and the lower circulation air pipe, the upper circulation air valve and the lower circulation air valve are mutually vertical and are coaxially arranged on the linkage shaft, the linkage shaft is connected with the executing mechanism, and a discharging hopper of the drying device is provided with a cross flow air hole. The cabin hopper type efficient food material drying device has the advantages that the goal of cyclically drying the materials from top to bottom or from bottom to top is achieved through the alternate opening and closing of the upper and lower circulation air valves of the double-path direction conversion device, afterheat air is exhausted from the drying device and returns to the heat supply device for continuously heating and drying the materials, the air supplementing and moisture discharge quantity of each stage in the drying process can be precisely controlled through an air supplementing moisture discharge valve device arranged on a drying air outlet pipe, and the drying efficiency, the quality and the heat energy utilization rate are improved.
