Efficient material cooling device

The utility model relates to an efficient material cooling device which comprises a cooling outer tube and a cooling inner tube arranged in the cooling outer tube, wherein a plurality of vertically arranged material channel straight tubes are arranged between the inner and outer walls of the cooling inner tube, and cooling passages inside and outside the material channel straight tubes are arranged between the cooling outer tube and the cooling inner tube. The efficient material cooling device provided by the utility model has the advantages that 1) the material channel is arranged in form of the straight tube, so that materials in the straight tube are not easy to block and circulate smoothly; and 2) the cooling passages are arranged inside and outside the material channel, the material channel is smaller in size, and meanwhile the cooling liquid in the cooling passages circulates smoothly to ensure that compact heat exchange can be performed between lower cooling liquid and materials, so that the cooling ef
