The shaft of the rice miller can be pulled out to check whether the sand roller and the main shaft of the rice machine are offset. That is, whether the air hole of the sand roller is aligned with the nozzle hole of the main shaft; whether the main shaft blow hole is accumulated or not, resulting in clogging of the spray hole.
