FIELD: heating, transportation.
SUBSTANCE: method of flowability restoration involves placing gondola wagons in a closed room, increasing the surface of direct contact between the frozen material and heat carrier by 1.2-1.7 times; for this purpose, several boreholes 300-600 mm of diametre are made in the material on its open surface and distanced from each other and from the gondola wagon wall by approx. 300-700 mm and from the gondola wagon bottom by 200-350 mm up to the borehole bottom end; then the heat carrier, for example air, is supplied to the room under the temperature of 60-80°C.
EFFECT: reducing heat energy consumption, accelerating the process of frozen material flowability restoration and improving efficiency.
