Abstract

Characterization of the reactor Dielectric Barrier Discharge Plasma (DBDP) has performed as a generator of ozone (O3) and as sources of input air. Ozone was measured on a variation of the voltage (4-8 kV) with the speed of air flow of 0,5, 1, 1, 3, 4, 5, 6, 8 and 10 L/min. Plasma reactor was used as ozone generators with spiral-cylinder configuration. Spiral electrodes were made of copper wire diameter of 1,2 mm,  coil length 50  mm  and diameter cylindrical electrodes while 10,3 mm of cooper sheets with thickness 0,25 mm. Dielectric material used is pyrex with diameter 2 cm and 1,1  mm for its thickness. The AC voltage was used as plasma generators with frequency of 16 kHz. This Research used plasma reactor with three  length variations that are 5, 10 and 15 cm . Results showed voltage, the length reactor and air flow rate input  affects the ozone concentration.  Ozone concentration increased while increasing voltage,  the length of  reactor  and the flow rate used is small. Amino acids  quality  in short bodied mackerel (Rastrelliger sp.) fed ozone for  12 days of storage showed that ozone could maintain the quality of short bodied mackerel amino acids . Key Words: Spiral-cylinder Electrodes, Ozone Concentrations

Abstract

Analysis of spiral-cylinder DBDP reactor on atmospheric pressure was done to explain spiral electrode impedance influence on ozone production. Variation of coil number (N): 10, 20, 30, 40, and 50 coil spiral applied to the spiral electrodes. Spiral electrode made of a copper wire with 0.4 mm in diameter and the inner and outer coils of each was 20 mm and 20.4 mm. Pyrex Tubing in diameter 3 cm and a thickness of 1 mm serves as a dielectric barrier cover spiral electrode. Cylindrical electrodes made from a copper plate with a length of 13.70 cm and thickness of 0.47 mm. a High voltage of AC has been used with a voltage up to 10 kV with frequency of 16 kHz. Free air supplied into the reactor with air flow rate of 6 L/minute. The results showed that at a constant N, ozone concentration decreased with the increasing value of the impedance (Z). Reactor DBDP most effective in terms of electricity consumption is on the DL = 20 mm, DK = 0.4 mm, and the number of coil N = 10 coils of wire with a power that is as high as 177.60 Watt and  Z=3,60x105Ω. Keywords : Number of coil, Spiral-cylinder electrodes, Ozone concentrations
