The present invention is a microwave heating device and has a microwave guide tube, two microwave transmitting modules, and a transmission module. The microwave guide tube forms a wave travelling path and has at least one conveying opening pair and at least one waveguide plate pair. The at least one conveying opening pair has two conveying openings respectively disposed on two opposite walls of the microwave guide tube along a conveying direction. The at least one waveguide plate pair is disposed in the microwave guide tube and has two waveguide plates parallel with the wave travelling path. The two microwave transmitting modules are disposed on two opposite ends of the microwave guide tube. The transmission module extends through the at least one conveying opening pair along the conveying direction.

Apparatuses, systems, and methods for heating a fluid or other material. The apparatuses may include a container (e.g., tube) in which a susceptor material is disposed. The susceptor material may convert microwave energy to heat, which may increase the temperature of a fluid or material in or adjacent the tube.

An applicator for thermal treatment of a product in which the product is exposed to electromagnetic microwave radiation in an exposure waveguide, in which the microwaves are coupled and propagate according to a single-mode propagation mode. The applicator includes a system for transporting the product in a continuous flow following the longitudinal direction of the cavity of the exposure waveguide between the inlet opening and the outlet opening. A product treatment device includes at least one applicator and at least one continuous wave generator CW. The product, heated by continuous microwave radiation CW in device, is subjected to a thermal treatment method in line with a temperature curve as a function of time, resulting in particular from a speed of movement of the product in the exposure waveguide and from a power of the microwave radiation coupled into the exposure waveguide at each coupling point.

A system for processing animal-based material is disclosed that includes at least one microwave generator, at least one microwave guide operatively connecting the at least one microwave generator to at least a first conveyor unit. The first conveyor unit is provided in a first housing that includes at least one opening configured to receive microwave energy via a first microwave guide and the first conveyor unit is configured to receive and process a quantity of animal-based material, which includes heating the animal-based material to a first temperature by applying microwave energy to the animal-based material within the first housing.

The present invention relates to a processing apparatus, in which a flying oil is heated, disinfected and/or pasteurized, sterilized. The present invention further relates to a method to treat a flying oil with radio-frequency wave.

A system for processing precursor material, including at least one microwave generator, at least one microwave guide operatively connecting the at least one microwave generator to at least a first conveyor unit, and the first conveyor unit provided in a first housing that comprises at least one opening configured to receive microwave energy via a first microwave guide. The first conveyor unit is configured to receive and process a quantity of precursor material, which includes heating the precursor material to a first temperature by applying microwave energy to the precursor material within the first housing.

A portable, sustainable, and efficient system and apparatus for breaking down processed solid plastic waste and other polymer-based feedstock into fuel oil, sustainable energy, carbon char, and other useful products. With minor modifications, biomass can also be treated. Distributed microwave heating sources and mechanical mixing effectively mix heat in a highly insulated reactor that protects the microwave components, makes fast pyrolysis possible, and thereby enables scaling down to compact and highly portable systems. Products include diesel, gasoline, propane, butane, and char. Product materials are distributed using tight temperature control and mechanical routing.

Systems and processes for use in heating articles include passing a carrier loaded with an article through a vessel inlet and into a first vessel portion and moving the loaded carrier in a first direction through the first vessel portion away from the inlet. During at least a portion of the movement through the first vessel portion, the article is contacted with a first fluid medium. The loaded carrier is moved carrier in a second direction opposite the first direction through a second vessel portion toward a vessel outlet. During at least a portion of the movement through the second vessel portion, the articles is contacted with a second fluid medium. In certain implementations, each of the first direction and the second direction are vertical.

A microwave heat converter includes a cylindrical waveguide cavity, a non-conductive conduit, and a microwave waveguide. The non-conductive conduit is arranged to carry liquid flowing through a central area of the cylindrical waveguide cavity. The microwave waveguide is configured to deliver microwave power along the cylindrical waveguide cavity in a TE(1,1) mode to heat the liquid. The heat converter may be used in various systems such as heaters, combi boilers, and absorption refrigeration systems.

A continuous asphalt mix system for using a microwave heating vessel at the point of production that includes a microwave energy suppression tunnel with one or more mesh flaps for substantially reducing or preventing the leakage of microwave energy from a microwave system, while having a continuous flow of product through the vessel and suppression tunnels. The suppression tunnels are installed on the inlet and/or the outlet side of the system and are sized to suppress leakage.
