FIELD: process engineering.
SUBSTANCE: invention relates to drying of water-bearing material, for example, manure. Proposed method comprises heating air flow in first heat exchanger to get in contact with first portion of manure to be dried, dividing heated air into first and second air flows, heating second air flow in heater, drying second portion of manure in direct contact between second heated air flow and second portion of water-bearing manure, cooling down second air flow to temperature of first cooling fluid in second heat exchanger using the first cooling fluid, mixing cooled first and second air flows in mixer and cooling down mixed air flow by second cooling fluid in third heat exchanger.
EFFECT: efficient recovery of secondary heat and its reuse at minimum power consumption.
