[0002] In the processing of melon seeds, drying and screening are two crucial and broadly defined steps. The purpose of the drying process is to remove excess moisture from the food through heating to prevent mold and decay, improve taste, and facilitate storage. The screening process is to separate the melon seeds into large and small particles.
