<p>Vacuum differential pressure in connection with disinfection is obtained following end vacuuming in a vacuum-tight packing material through atmospheric pressure and volume reduction. The apparatus includes an exhaust air filter comprised of a germicidal filter. When the vacuum differential pressure reaches e.g. 300 mbar, disinfectant in liquid or gas form is added such that a pressure of 500 mbar for disinfection is ensured in all corners. The packing material is closed by volume reduction after a retention time upon increase in negative pressure until maximum negative pressure is reached.</p> |
