FIELD: drying solid materials. ^ SUBSTANCE: method comprises cooling the exhaust drying agent thus transporting heat from it to the main heat transfer agent by means of contact heat exchange and heating incoming air with transporting heat to it from the additional heat transfer agent by means of contact heat exchange. The additional heat transfer agent is heated by means of main heat transfer agent using surface heat exchange, and mean heat transfer agent is cooled by transporting heat to the coolant by means of surface heat exchange and additional heating of the incoming air by means of the cooling agent with the use of surface heat exchange. The main heat transfer agent is made of water, and additional heat transfer agent is made of oil. When the exhaust drying agent is cooled, dust may be removed from the main hear transfer agent. ^ EFFECT: reduced sizes and material consumption. ^ 1 dwg |
