The utility model belongs to the field of baking and heating and relates to a novel circulating dehumidifying air channel. The novel circulating dehumidifying air channel comprises an evaporator, a heat pump main machine and a drying room, a first circulating fan, a second circulating fan and a dehumidifying louver are arranged in the drying room, the output end and the input end of the heat pump main machine are connected with a first condenser and a second condenser respectively via a high-pressure delivering pipe and a low-pressure backflow pipe, the first circulating fan and the second circulating fan are oppositely arranged on two sides of the drying room, the first circulating fan is arranged upwardly, and the second circulating fan is arranged downwardly. The novel circulating dehumidifying air channel has the advantages that a double-circulating hot air structure is adopted, an indoor circulating air channel is improved, and the problem of unevenness in wind power and heat quantity in the drying room is solved, so that drying effect and efficiency are improved; the circulating fans integrate with a dehumidifying function, so that equipment cost and power consumption are reduced.
