Silica gel desiccant can be reused, there are two methods:
1, the Sun prolonged sun exposure (but water not drying out).
2, in theory, the silica gel desiccant (moisture beads) baked at high temperature, can be reused. Can 80-120 bake adsorbed moisture baked out, achieve the purpose of repeated use, but not recommended. Package layer is heat seal adhesives, temperature of 80-120 degrees, so the bag tore bake (most of the packaging cannot withstand the high temperatures and therefore at low temperatures and long drying. And direct the package baked materials cost is very high, and not cost-effective. Therefore, from the baking of human, material and operational costs, reuse is not recommended.
