These air sanitizers are suitable for supermarkets, fruit and vegetables cells, for food processing industries.
In developed countries the traditional retail and distribution sector for the fruit&vegetable sector produces about 10% of vegetal waste.
A relevant portion of that waste is caused by several alterations due to the change of natural environmental, physical and chemical conditions.
The most common effects observed are the different appearance and taste – namely decrease in weight, freshness, aroma and flavour, the colour, the degree of ripening, and the presence of moulds and pathogens. The main causes of these phenomena are due to the natural physical properties of the air and to the intrinsic characteristics of these products, which produce ethylene (natural ripening hormone) in the post- harvest phase. Ethylene triggers the ripening process of the products, provoking an over-ripening and deterioration if not adequately controlled.
Nanohub developed a solution to eliminate and control the ethylene. This solution promotes an improvement in the preservation of fruit and vegetables and can be realized in two modalities:
Establishing a system for theair control directly in the sales areaof the fruit and vegetable products through a hood system filtering the air and destroying ethylene.
Installingdevices in the storage cellsand warehouses of the goods (in particular for “climacteric” fruit, which produce more ethylene)
Moreover, through the implementation of the air control directly in the sales area, besides a better preservation of the products and a consequent extension of the shelf life, it is possible toavoid moving the productsonce displayed on the shelves back into the conservation cells during the night, leading to benefits in terms of organization.
The devices developed by NANOHUB are:
Removal of ethylene, bacteria, moulds, and micro-toxins present in the air and, indirectly, on surfaces
Negligible power consumption
Possibility of fruit and vegetables preservation at higher temperatures (energy saving)
No chemical products are used
Method compatible with the “Bio” productions
No UV rays are released from the device
No decomposition waste
Only an infinitesimal emission of CO2and water vapour
