How to Make Garlic Powder

Can you tell me how to make and dry garlic for powder?

Starting with fresh garlic bulbs, the cloves must be separated and cut into small pieces, about 3-5 millimetres across. These are dried in sun or in low heat (50 degrees Celsius). Once throughly dried, the pieces are run through a pulverizer (can be an electric coffee grinder permanently deployed for herb processing). It may be necessary to sieve the skin fragments out from the final product.
