PROBLEM TO BE SOLVED: To provide a method for producing a granular detergent which is excellent in solubility and of which the solidification is excellently suppressed.SOLUTION: There is provided a method for producing a granular detergent, which has a granulation step of granulating a component (A): surfactant-containing particles, a component (B): a bicarbonate of an alkali metal, and a component (C): a binder. In the method, the granulation step has mixing operation to mix the component (A), the component (B) kept at lower than 50°C, and the component (C) kept at 50-70°C. It is desirable that in the granulation step, a kneaded product of the components (A) to (C) is obtained via the mixing operation and the kneaded product is pulverized. |
