The invention relates to a high-speed humification method for realizing targeting recycling of biological heat and a device thereof. The method comprises the following steps: placing humification raw materials into a silo type compost reactor; supplying air at a low flow rate in a temperature rise period and a heat preservation stage of humification; leading out air in the silo type compost reactor from top and then conveying into a stockpile on an easily radiating surface; discharging from a bottom air outlet; supplying air at a high flow rate in the cooling period of humification; and discharging air in the silo type compost reactor from a top air outlet. The device comprises the silo type compost reactor, an air supplying mechanism and a branch mechanism, wherein the top air outlet and the bottom air outlet are respectively formed in a side wall of the silo type compost reactor up and down. Compared with the prior art, the method provided by the invention has the advantages that the periodic air supply at
