Abstract

Applicable in the preservation, ripening and maturation of fruit and the like the purpose being to maintain the levels of CO2 and ethylene in the rooms 4 within a particular margin for which it uses an automatic machine 1 which is connected to an infrared carbon dioxide analyser 3 and to several air extractors, which carry out the ventilation of the rooms 4 when the carbon dioxide concentration level is exceeded. It is characterised in that the automatic machine is connected to several electric valves 8, 9 which in turn are connected to an ethylene reservoir 11 and to a flow meter 7, which is likewise connected to the automatic machine 1 so that, when the air is extracted, it evacuates the carbon dioxide and therefore the ethylene in one of the rooms 4 there is generated the opening of the corresponding electric valve 8 or 9, dictating the entry of a flow of ethylene into said room 4 for a certain time which is a function of the evacuated flow and the flow of ethylene introduced into the room 4 which flow is in turn regulated by the automatic machine 1 acting on the electric valve 8 or 9, maintaining the levels of carbon dioxide and ethylene. The automatic machine 1 is connected to a sensor 5 for each of the rooms 4 so that, when the door of the room 4 is opened, the entry of ethylene in the corresponding room 4 is enabled.
