Combined mechanical, electrical and electromagnetic device allowing optimised drying of corks or another product by the association of ventilation and the application of microwaves

摘要

The present invention relates to a combination including a mechanical, electrical and electromagnetic device allowing optimised drying of corks or another product by the association of air ventilation. The device comprises a motorised circuit, for conveying the corks to be treated, it is set out with tunnels judiciously installed in the system, these are equipped with several generators and microwave applicators in accordance with the standards in force. The drying treatment takes place, during a passage at controlled speed through the tunnels equipped with an agitator system, capable of homogenising the product. The proportion of microwave energy is reduced to the useful minimum to create a migration of water from the inside to the outside of the corks through the existence of a heat gradient between the core of the stopper and its periphery. The water which has reached the surface of the corks is discharged by the dehumidified hot air. This air is recycled using a heat pump or any other source of energy. IMAGE
