The present invention relates to a processing method of bay salt and a processing system therefor, which enable to reduce the time for processing bay salt with a high quality and producing a product by removing foreign substances in bay salt, washing the bay salt with foreign substances removed, dehydrating, and improving the transfer and packaging processes of the bay salt. The processing method of bay salt comprises a bay salt loading step of inputting the bay salt material； a washing step of washing the bay salt by precipitation-washing and spray-washing the input bay salt with seawater or a saturated saline solution to remove foreign substances and soil on the surface of the bay salt； a dehydration step of removing foreign substances which have not removed in the washing step by blowing the wind from the down upward with a blower equipped on the lower end of a net conveyor once the bay salt washed in the washing step is transferred via the net conveyor； a drying step of drying by blowing the wind from the down upward or from the top downward with a blower equipped on the lower end of the net conveyor once the bay salt dehydrated in the dehydration step is transferred via the net conveyor, and drying in a dryer having a sieve at 50 degree or less for 24 hours, wherein the drying efficiency is increased with a dehumidifier equipped with a heat exchanger and a cooler； and a packaging step of classifying the bay salt dried in the drying step into coarse bay salt and find bay salt in a separate packaging room installed with a dehumidifier and an air conditioner, and packaging a predetermined amount of bay salt, in which the diameter and the volume are calculated.
