FIELD: medicine. ^ SUBSTANCE: invention is designed to manufacturing wrappings for packaging and transportation of foodstuff: milk, juice and other beverage foods. The device (1) for bacterial purification of packing-sheet fabric (2) contains a bath (6), contact rollers (12), distributing rollers (13), power supply unit (16) and transportation system (5, 7, 9, 17), which contains transfer tank (5) and transfer unit which is the first pump (9) for transportation sterilising fluid from transfer tank (5) into the bath (6). The bath (6) is equipped with device of self-draining (11) for return of sterilising fluid into the transfer tank (5) when the fabric (2) is still in the bath (6). The way of bacterial purification of fabric is characterised by the process when sterilising fluid is conveyed into the transfer tank, then into the bath with the first pump (9), thereby the bath (6) is designed as self-draining for return of sterilising fluid into the transfer tank (5) when the fabric (2) is still in the bath (6). Hydrogen peroxide is used as sterilising fluid. ^ EFFECT: invention of more reliable device, avoidance of risk of adsorption sterilising fluid by fabric edge also during short stops and power outage. ^ 15 cl, 2 dwg |
