Probably washing the Sweet potato with high pressure may help, alternatively you may use the vibrating machine having pores so that small stones if attached to the sweet potatoes can be removed along with the water. *Cheers*
I'd like to know the whole process in order to understand the chain and implementation of new step to reduce your problem.
Since potatoes can grow around stones, you won't be able to shake all stone contaminants off. It would help to get more details about your line, but for now, I suggest looking into dual energy x-ray inspection, which is optimized to find low density contaminants like stones.
Actually we are washing by machine under high pressure, but can not remove all. Can not apply vibrating machine because it will be damage skin of sweet potato.Probably washing the Sweet potato with high pressure may help, alternatively you may use the vibrating machine having pores so that small stones if attached to the sweet potatoes can be removed along with the water. *Cheers*

Our process: washing>> cutting into pieces>> steaming>>> freezing by iqf>>> packing>>> xray inspection.
Please give me your idea

How can xray remove all by xray inspection?

x-ray system can detect stones and reject product if it has stones. dual energy x-ray will perform better for stone detection. with bulk inspection system, you may inspect product prior to packing.
