We made a multi-layer conveyor sterilizing system using UV rays to prolong a storage period of dried marine products. The system is composed of 5 layer conveyor belt of 3 m long each, thus 15 m long in total. It is designed to radiate UV rays for 10 minutes the dried marine products, and can process 300 kg/hour. Eight UV lamps of 30 cm long and 15 W of power with 254 nm wave length are installed in parallel, 15 cm high above in each belt, and 40 lamps in total. The whole system is covered by 1 mm thick metal plates to block the UV rays except a front side which is covered with 5 mm thick plastic plates coated with UV protection film to survey inside of the system. A sterile ratio is about 99.97% with 10 minutes sterilization using this system.
