There is provided a process for manufacturing a granular igniter, which facilitates control of the igniter preparation, handling of the granule igniter and improvement in manufacturized yield. The present invention also provides a process for manufacturing a granular igniter which is free from toxic gas generation when burned and which has excellent fluidity. The present invention moreover reduces the number of manufacturing process facilitating the production process, and reducing production costs. An igniter containing boron and potassium nitrate are mixed together with water in a homogenizer to form a homogeneous slurry. The mixing ratio of the igniter to the water is set in the range of 1.0:0.6 to 1.0:1.6 in terms of weight ratio. The slurry is sprayed in a spray dryer where it is dried and granulated. Micropowder, which failed to be collected as the granule, is recovered through a cyclone, and recirculated as the raw material. |
