Dried sea cucumbers are highly value-added products. Currently, solar radiation is mainly used to produce the dried sea cucumber, but solar radiation drying requires more than 5 days under suitable environment. Such a long drying period causes sanitation problems as well as more cost to produce the dried sea cucum- ber. Our study showed that the far infrared radiation drying (FIRD) dramatically shortens the drying time. The quality of dried sea cucumber using FIRD was better than that of the air drying, because the surface hardening of the sea cucum- ber was minimized by the radiation heating mechanism. FIRD might be a good technology to replace the solar drying as well as the air drying to produce the dried sea cucumber.
