DECONTAMINATION EQUIPMENT USING OZONE IN AQUEOUS SOLUTION

The invention relates to a horticultural product decontamination equipment using ozone in aqueous solution, intended to reduce the number of pathogenic germs from the external surfaces of such products and to extend their shelf-life. According to the invention, the equipment consists of a framework (1) having mounted thereon the transport system (2), the collecting table (3), the supply tank (4), the ozone treatment tunnel (5), the collecting basin (6), the ozone discharge system (7), the ozone generation system (8) and the system (9) for ozone distribution in aqueous solution, consisting of a plurality of nozzles (10) with conical distribution and square footprint, connections (11) and pipes (12) to be coupled to the outlet connection of the generator of ozone in aqueous solution by means of a quick coupling (13), the ozone treatment tunnel (5) consisting of a metal enclosure having a product inlet zone and a product outlet zone, an air-pressure equalizing system (15), a screen (16) with round meshes for homogenizing air currents needed to entrain ozone vapours for discharging them from the equipment, and the ozone discharge system (7) consisting of a gauze-like metallic filter (17), a connection (18) as a passage from a rectangular cross-section to a circular cross-section, the ventilation piping (19), the centrifugal fan (20) for corrosive medium together with some connecting elements (21), allowing variable intake flow-rates to be reached due to the frequency variation of the fan supply current, by using the frequency converter (22) it is provided with. Invenţia se referă la un echipament pentru decontaminarea cu ozon în soluţie apoasă a produselor horticole, în vederea reducerii numărului de germeni patogeni existenţi pe suprafeţele exterioare ale acestor produse şi prelungirii duratei de păstrare. Echipamentul conform invenţiei este constituit dintr-un cadru (1) pe care se montează sistemul (2) de transport, masa (3) de colectare, cuva (4) de alimentare, tunelul (5) de tratare cu ozon, bazinul (6) de colectare, sistemul (7) de evacuare a ozonului, sistemul (8) de generare a ozonului şi sistemul (9) de distribuţie a ozonului în soluţie apoasă, alcătuit din mai multe duze (10) cu distribuţie conică şi amprentă pătrată, racorduri (11) de legătură şi conducte (12) care se cuplează la racordul de ieşire al generatorului de ozon în soluţie apoasă prin intermediul unei cuple (13) rapide, tunelul (5) de tratare cu ozon fiind alcătuit dintr-o incintă metalică
