The installation includes a microwave heater station () having a microwave applicator, and a support () suitable for supporting the receptacles () in the heater station. The support () has at least one receptacle zone () which is defined by the surface (A) of the support and by a metal band (A,B) fixed to the support. The zone () serves to support a receptacle () whose bottom stands on the surface (A) of the support and whose side wall (B) is surrounded by the band. The support can be a conveyor bringing the receptacles into the heater station.

Installation for microwave heating of a product held in containers

Container designed to contain a product having to be heated by applying microwaves, the container having a side wall () and an end wall () formed by a base or a lid and means (A) for limiting the penetration of the microwaves through the side wall (), compared with the penetration of the microwaves through a central region of the end wall (). Advantageously, the container according to the invention further comprises means (A) for concentrating the microwaves in a central region of the end wall (), the said means being formed by an excess thickness of a dielectric material, the dielectric constant of which is at least equal to 1.5, preferably greater than 2.

Microwave heating container

A microwave applicator device for continuous heat treatment of elongate products comprises an applicator housing that defines a generally rectangular waveguide cavity and at least one excitation system for exciting the cavity with microwaves propagating in TE.sub.01 transverse electric mode, the system including at least one microwave generator associated with a feed waveguide connected to the cavity via a window formed through a wall of the cavity. The front and rear walls of the feed waveguide are respectively connected to the front and rear edges of the window, and the feed waveguide is associated with a guide flap extending in the cavity in the vicinity of the rear edge of the window, and with a guide member provided substantially facing the window. The front and rear walls of the feed waveguide include respective front and rear connection portions situated in the connection zone for connection with the window, and each being curved forwards substantially in the form of an arc of a circle, the guide flap is situated substantially in line with the rear connection portion, and the excitation system includes means for adjusting wave coupling.
