Title:
A METHOD OF ASEPTICALLY STORING A BULK STERILE PRODUCT
Document Type and Number:
WIPO Patent Application WO2003070024
Kind Code:
A8
Abstract:
The invention refers to a method of aseptically storing a bulk sterile product in stationary storing tanks or containers designed for transportation by road, fluvial and marine systems, the method comprising the steps of: cleaning the inner area of a container by applying chemical cleaning agents; filling the cleaned container (10) completely with clean, potable water, while expelling all the air contained therein; sealing and pressurizing the container (10) with an inert gas in order to expel the water and to create a pressurized inert gas atmosphere within the container; applying a liquid sterilizing agent to all inner surfaces of the container (10); removing said liquid sterilizing agent while maintaining the pressurized inert gas atmosphere; feeding the bulk sterile product into container and maintaining said container (10) sealed with an internal pressurized inert gas atmosphere. In a variant of the above method, the sterilization of the container is carried out just after the cleaning step, then the liquid sterilizing agent is drained and the container is filled with a sterile liquid to expel all the air contained in it. After-wards, the container is sealed and pressurized with inert gas whereby the sterile liquid is expelled from the container so that the latter can receive the bulk sterile product to be stored.
