ansonbb,
I also did it at home by myself. Do you have blender at home? If you have, you soak the 淮山 a while first, so that the dirty and sour taste will come out, then let it dry (if you have oven, you can put it in the oven to make it dry), when they are totally dry, then you can use the blender to make them as powder.
