Abstract
An electronic device for generating ozone is deployed within standard, perforated, plastic or cardboard distribution trays of fresh fruit or vegetables. The ozone disables ethylene and destroys airborne and surface contaminating microbial organisms, thus extending the life of the produce. The electronic unit is sized such that it sits within individual palletised trays of produce and may have dimensions of 100m x 60mm x 30mm. Ozone is supplied to the immediate local atmosphere and ensures that adequate ozone reaches all of the produce when packed in shipping containers. The ozone generating unit is portable and preferably battery-powered. It comprises a rigid polymer casing enclosing an electronic unit with discharge needle assembly and grid, which generates and passes both anions and ozone, at predetermined, controlled levels.
Description
A PRESERVATION UNIT FOR FRESH PRODUCE IN SUB-PALLET, DISTRIBUTION OUTERS DURING PROLONGED CONTAINERISED TRANSPORT.
Introduction to the lnventioQ
I Field of the Invention
2. The present invention relates to a device, controfled by an electronic circuit design for the generation of both ozone and anions, to be employed in euro-trays, or similar sub-pallet containers.
3. The device has been designed for use within fresh produce distribution containers to provide the controlled release of ozone and anions, nto the immediate headspace, which will both allow the inhibition or destruction of microbial food spoilage organ'sms present on the product and disablement of ethylene produced by the product.
4. Description of the Related Art
5. Fresh produce, such as top fruits, stone fruits and soft fruits, as weli as a wide rage of whole vegetables, delivered, out of season, into the EU markets are in the main grown in the southern hemisphere and are shipped in refrigerated, containerised loads, with journey times of several weeks.
6. Within the containers, the fresh produce is generally packed in standard, perforated, euro-sized, plastic distribution trays or their cardboard equivalents and then palletised.
7. Despite refrigeration, the high humidity within the containers combined with extended journey times promotes the development of microbial spoliage organisms, which can be the cause of a significant reduction in the commercial value of the load, 8. Also, despite refrigeration, if the fresh produce within the container is climacteric, it will generate ethylene into the headspace with the potential of promoting accelerated rpeninq leading to senescence and accelerated deterioration of the product, again leading to a significant reduction in the commercial value of the load.
9. These problems have been recognized and addressed, in the first instance, by the deployment, within the standard, perforated, euro-sized, plastic distribution trays or their card equivalents of pads containing sodium metabisulphite whicn, in tne presence of an elevated relative humidity (RH) will generate sulphur dioxide into the local ambient atmosphere to act as a microbial suppressant.
10. The use, however, of sulphites within the food industry has, on the grounds of food safety, been under review for some time, especially by the EU, where prohibition is* being sought and in some case implemented.
I
11 In the case of ethylene, its removal from the atmosphere within containerised loads has been attempted by the introduction of ozone into this atmosphere 12. Ozone is a powerful oxidising agent and is thus extremely effective, even when at comparatively ow levels, in the oxidative disabflng of ethylene.
13. Unfortunately, due to the pauetised loading of shipping containers, the abUity of ozone dehvered into a shipping container heauspace to penetrate to the product within the standard, perforated euroszed, plastic distribution trays or their cardboard equivalents, which are situated in the centre of stacked pallet loads, at levels that are stM ethylene destructive, is minimal or non-existent, without elevating the initial level of ozone within the container headspace atmosphere to one where it is certain to cause damage to the products in those trays situated on the outside of the pallet stacks.
1.4. In addition, ozone, even at levels of O.Olppm in the atmosphere of a container apart from tne oxidatre disabling of ethylene is also capable of destroying both airborne and surface contaminating, microbial spoilage and pathogenic organisms, thus dispensing with the need to deploy sulphur dioxide generating pads.
15.The device in this invention is deployed, as a portable, independent unit, with a battery operated, low voltage supply and has been designed to be of a scale that allows it to be easily accommodated, inserted amongst the fresh produce contained within the standard perforated, euro-sized (600mm x 400mm x 250mm ann size derivatives) plastic distribution trays or their card board equivalents.
16.The device has the nominal dimensions of 100mm x 60mm x 30mm.
17.The device, in the preferred deployment, is placed amongst the fresh produce concerned in a position that is central and near the top of the packed standard, perforated, euro-sized, plastic distribution trays or their cardboard equivalents.
18. The device generates and delivers ozone into the local atmosphere of the standard, perforated, euro-sized, plastic distnbution trays or their cardboard equivalents and the product contained, at levels, which will both oxidatively disable the molecules of ethylene and destroy both airborne and surface contaminating microbial spoilage and pathogenic organisms present.
