The invention discloses a circulating dryer for cereals. The circulating dryer for cereals comprises a radiation drying section, a grain discharging section, a hot air drying section and a grain storing section, which are arranged on a base in sequence from the bottom up; a material circulating conveyer is arranged between the radiation drying section and the grain storing section; one side of the radiation drying section is communicated with a heat source that can produce a heat medium; an induced draft fan and an air mixing chamber are respectively arranged on two sides of the hot air drying section; the inlet of the air mixing chamber is communicated with a heat medium outlet of the radiation drying section; the outlet of the air mixing chamber is communicated with the induced draft fan through the hot air drying section. The circulating dryer has the advantages that not only can hot air drying be realized individually, but also hot air drying is organically combined with radiation drying, so that heat of the high-temperature heat medium is sufficiently used in high level and low level, the heat efficiency is high, the energy consumption is low, the drying is sufficient and uniform, the drying cost is low, the temperature is uniform, and the safety is good.
