Abstract
An industrial apparatus to heat foodstuffs, particularly meat-products, including a generator of voltage oscillating at a predetermined radio frequency and an application system to generate an electromagnetic field oscillating at a predetermined radio frequency. The electromagnetic field includes electric and magnetic components which combine, both involving a food product, also a large-size one, to heat at a uniform temperature the entire mass of the food product (P) itself. The application system includes a first application device (12) connected with the generator of oscillating voltage and having the shape of a tunnel.
Claims19
Industrial apparatus to head food products, comprising a generator for generating oscillating voltage at a predetermined radio frequency, a first application device connected with the generator to generate a first electromagnetic field oscillating at the predetermined radio frequency, a second application device including at least two opposed portions between which, during a heating operation, a food product is placed, the second application device being crossed by radio frequency electric currents formed by the first electromagnetic field of the first application device to induce a second oscillating electromagnetic field which is superimposed onto the first electromagnetic field, said electromagnetic fields in combination, heating an entire mass of a food product at a uniform temperature.
Industrial apparatus to heat food products, comprising a generator for generating oscillating voltage at a predetermined radio frequency, and a tunnel-shaped inductive application device to transform the oscillating voltage generated by the generator into an electromagnetic field, and a conveyor to continually insert and extract individual containers containing food products into and from respective opposed ends of the tunnel-shaped inductive application device.
An apparatus to heat food products comprising:
- a generator for generating oscillating voltage at a predetermined radio frequency;
- a tunnel-shaped inductive application device connected with the generator to generate a first electromagnetic field oscillating at the predetermined radio frequency;
- a plurality of containers made of a conductive material, each of the containers comprising a tray containing a food product and a cover covering the food product within the tray;
- and
- a conveyor for conveying the containers through the tunnel-shaped inductive application device;
- wherein, during a heating operation, the first tunnel-shaped inductive application device generates the first electromagnetic field which provides radio frequency electric currents onto each of the containers to induce an oscillating magnetic field in each of the respective containers, which is superimposed onto the first oscillating electromagnetic field to heat the food product in each of the respective containers at a uniform temperature as the containers pass through the tunnel-shaped inductive application device.
