Optimation of ozone capacity produced by DBD plasma reactor: dedicated for cold storage

The optimation of ozone production generator that used for cold storage has been done. Ozone generator was constructed by using Dielectric Barrier Discharge Plasma Reactor with single pyrex dielectic. Plasma was generated by HV AC with voltage from 0.5 kV to 11 kV, and frequence of 1 kHZ. This research was conducted in two treatment namely control treatment and ozone treatment by tuna fish, milkfish and shrimp. Ozone treatment are stored into Cold Storage (2 m x 2 m x 2.5 m), temperature (2°C-8°C) with average concentration of ozone distributed into the cold storage for 24 points is 6.2 ppm ± 0,14 ppm. The result showed that the optimum to generate ozone by using variations of power input, air flow rate. we obtained that the highest efficiency of 320 grams / kWh and ozone capacity of 65 grams / hour at 15 L / min flow rate with an input power of 210 watts. The concentration of dissolved ozone in the water containing fish and shrimp is almost the same that is equal to 2 ppm ozone flow for 60 minutes with ozone generator production capacity of 65 gram/hour. We test proximate of milkfish, tuna fish, and white shrimp that storaged in cold room (2°C-8°C), and we found that until days 15 still meet SNI 01-2729.1-2006, as fresh fish and shrimp. (paper)
