The invention discloses a uniform-
heat energy-saving type grain dryer. The dryer comprises a dryer box body, wherein a feeding bin is communicated with an upper part of the dryer box body, a discharging
barrel communicated with the feeding bin is mounted at the top in the dryer box body, a heating base is fixedly mounted at a lower part in the discharging
barrel, a plurality of channels are evenlyformed in the heating base and located on the periphery of a semicircular protruding part, a device cavity is formed in the middle of the interior of the heating base, a heating
pipe is installed inthe device cavity, a spiral conveying rod is movably inserted into the channel, an air draft end of a draught fan is communicated with an air inducing
pipe, the other end of the air inducing
pipe is communicated with the discharging
barrel, and the other end of the air outlet pipe is communicated with the
air cavity. The dryer is advantaged in that the heating base is heated through the heating pipe, grains in the channels can be evenly heated and dried, the hot air generated in the heating process is exhausted into the
drying box through the draught fan to be dried and then enters the
air cavity, the grains can be dried again, the
drying effect is improved, and heat waste is avoided.
