Definitions
- the present invention relates to a modular industrial microwave oven for drying or heat treatment of products by microwave.
- the invention relates to a continuously operating device which, by its modular structure, is suitable for most industrial energy uses ranging from 10 to several hundred kilowatts.
- a microwave oven which is characterized by at least one module consisting of a metal box divided into three compartments by partitions having openings, by several microwave generators, for example 25 at 50 low power magnetrons, these generators being arranged in the external compartments such that the hot air is propagated directly in the median compartment by said openings in the partitions, the median compartment constituting the applicator oven proper.
- Several waveguides are mounted on the metal box with radiators so that the maximum amount of microwave energy is applied in the middle compartment.
- fig. 1 shows the construction of a usual industrial microwave installation.
- the reference 1 designates a microwave generator which is connected by an isolator 2 and a passive transfer part 3, for example a circulator, to a microwave applicator 4 in which the product to be treated is placed.
- Figs. 2 and 3 show a modular unit according to the invention.
- This unit 10 essentially comprises a metal box 1 divided into three compartments 11, 12 and 13 by partitions 14 and 15.
- the external compartments 11 and 13 contain the power units including a group of microwave or magnetron generators 4 and the power transformers 8; the middle compartment 12 forms the actual applicator in which the product is treated.
- the partitions 14 and 15 between the compartments have openings, 16 and 17 respectively.
- the magnetrons 4 are arranged with respect to these openings 16 and 17 in such a way that the hot air coming from the cooling of the magnetrons is propagated directly in the applicator compartment 12.
- the openings 16 and 17 are each provided with a mesh 18.
- the microwave energy of the magnetrons is applied in the compartment 12 by means of radiators 3 which are uniformly distributed along each waveguide 2.
- the location of the waveguides 2 as well as that of the radiators 3 are chosen so that the coupling between the different magnetrons can be done without losses. In this way, not only is the presence of insulators and circulators avoided, but also the efficiency is significantly increased.
- the position and distribution of the radiators 3 above the middle compartment 12 are determined in such a way that the interaction between the magnetrons is practically eliminated.
- radiators in a microwave oven project of 36 kW (18 x 2 magnetrons of 1 kW) working at the frequency of 2.450 MHz and used for drying plasticized paper has seventy-two radiators distributed over eighteen rows of four with a spacing of about twenty-five centimeters between rows, the radiators in each row being spaced from each other by about fifteen centimeters.
- the external compartments 11 and 13 are placed under a variable air pressure par. separate fans 9. Thus not only the cooling heat of the magnetrons but also that of the transformers are used in the enclosure of the compartment 12. The evacuation is done by the outputs 5.
- a conveyor belt 6 made of a flexible and non-absorbent material, for example polyethylene, which passes through the middle compartment 12 for transporting the product to be treated.
- a flexible and non-absorbent material for example polyethylene
