Application of microwave in food preservation

Food preservation has become nowadays a major priority. Classical methods of storing food relies on controlling the temperature and humidity in storage areas. The present work is proposed another method which relies on complete air purification storage space. It is known that leading to food spoilage is the presence of bacteria and microorganisms. The presented method is based on purifying the air by destroying them using three tools: air is passed through a chamber where they are generated electromagnetic waves in the microwave range, knowing that they are destroying microorganisms and is then exposed to ultraviolet light and last through a process of ozonization. In this work the command of the magnetron that generates microwaves and ozone generator are presented. The device has been designed to allow a control them more flexible that they can be tested as many dosages microwave, ozone or ultraviolet light so they can be experienced as many scenarios in order to obtain a storage times as long as possible and also power consumption reduction.
