Device to apply micro-waves for the treatment of sheet or mat products

摘要

This is an applicator device for microwaves for the treatment of products (2, 15, 28, 41, 55) in sheet or mat form, comprising a housing (3, 13, 20, 40, 50) defining a parallelepipedal waveguide cavity of dimensions a x b x L in a triple right-angled reference frame Ox,Oy,Oz, the said housing being elongate along Oz and provided with slots (4, 18, 27, 42, 56) for passing the product to be treated into the cavity in a plane parallel to the plane Ox,Oz, and means (10, 17, 31) of exciting the cavity in Transverse Electric Mode (TEM), in order to create an electric field (E) inside the said cavity in a direction substantially parallel to Ox. The housing is such that the dimension a of the cavity is greater than a value substantially equal to the dimension b of the said cavity. …IMAGE…
