<p>The invention relates to an installation and process for treating the apples with ozone with a view to storing the same. According to the invention, the installation comprises an ozone generator (2), of low capacity (0,75...5 g O3/h), a compressor (1), an ozone flowmeter (3), taps (4, 5, 6, 7), an air filter (8), a pressure regulator (9), an air flowmeter (10) and an apparatus for measuring the ozone concentration (12). The installation comprises a treating chamber (11), supported on the legs (23) and having metal walls, of which a movable wall (20) that is sealed with siliconic polymer , and a wall (21) made up of glass, a mixing chamber (17) wherein there is mixed the air with ozone, said chamber being provided with the inlet nozzles (14 and 15), with a fan (18) and with a toroidal static disperser (19) and also with a safety module (13) through which passes the residual gas, before being discharged into the atmosphere. through the discharging nozzle (24). According to the invention, the process consists in treating the apples with ozone placed into standard boxes, in the treating chamber, for 0,5...1,5 h, the treating mixture containing air with an ozone content of 10...50 ppm.</p> |
