PURPOSE:To inexpensively obtain granular agar having large grain size and high granular strength and capable of readily dissolving by feeding air to powdery agar to allow the agar to flow and spraying an aqueous solution of agar into powdery agar kept in the flow state. CONSTITUTION:Air is fed from a blower to powdery agar fed from an agar- supplying device 4 into a flow tank 5 to allow the powdery agar to flow and then an aqueous solution of agar kept to a temperature causing no solidification is sprayed from a sprayer 10 into the powdery agar 8 kept in the flow state to granulate the powdery agar. |
