Embodiment Construction
[0028] The method of the present invention as described above in a general manner allows the storage of large quantities of bulk sterilized products such as "natural" orange juice for long periods of time, as well as transport to long distances, so that these products can be kept in a location adjacent to product extraction or even Located in storage tanks at a considerable distance from the extraction location. This is the case when the product is stored in tanks for transport by road, river and ship systems etc., in view of the need to maintain the high quality of the product in terms of taste and original properties supplied to the customer market, This is associated with proper equipment and under controlled operating conditions.
[0029] Although for example in the case of pharmaceutical products or the like the present invention can be used to transport different kinds of products requiring aseptic storage and transport environments, which are maintained under specific c...

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.
Description
technical field [0001] The present invention relates to a method for the aseptic storage and transport of sterile products in bulk, especially liquids such as "natural" orange juice, which are stored and transported over long distances by road, river and ship systems food product. Background technique [0002] In the handling of bulk food products to be transported to the final customer, it is necessary to store large quantities of products in storage tanks for a long time and under sterile conditions in order to guarantee their quality. This period may exceed one year. [0003] In order to meet the above conditions, it is necessary to prevent the introduction of any contaminating microorganisms in the storage tank, since even trace amounts are sufficient to contaminate the entire contents of the tank. [0004] Constantly maintaining the temperature within the desired parameters according to the characteristics of the product is extremely important to guarantee the quality...
