摘要:
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.

A radio frequency apparatus (1) for thawing food products, through the use of an oscillating electromagnetic field, comprises a continuous conveyor belt (2), on which the food products are positioned, elements (3) for supporting and for moving the conveyor belt (2) forward, an inlet section (4), for the introduction of the food products to be thawed, a central section (5), defining a tunnel in which the food products are thawed, an outlet section (6), from which the thawed food products come out, at least one oscillating voltage generator (9), for generating the oscillating electromagnetic field, and elements (21) for washing and/or sanitizing the conveyor belt (2) and/or the inlet section (4) and/or the central section (5) and/or the outlet section (6).
摘要:
Industrial apparatus for applying radio-frequency electromagnetic fields to semiconductive dielectric materials comprises a radio-frequncy voltage generator (10) and an applicator device (1) for applying radio-frequncy electromagnetic fields. The applicator device (1) comprises a plurality of electrodes (12, 13, 14, 15) electrically connected to the electrical generator (10) for generating between then a radio-frequency electromagnetic field with electrical and magnetic components arranged in a preferential direction. The applicator device (1) further comprises at least one pair of equipotential electrodes (12, 14) substantially aligned in the preferential direction and material transportation means (32) for housing and transporting semiconductive dielectric material within the applicator device (1) in a direction substantially parallel to the preferential direction.
摘要:
An apparatus and a method of drying and/or treating loose products such as food products, for example corn, flour, seeds in general, spices, tea and coffee, dried pulses, dried or shelled fruit, like hazelnuts, dry food products in general, such as dried mushrooms, etcetera, the treatment which the aforementioned loose products can be subjected to being of the type such as disinfestation, sanitization, pasteurisation, sterilisation, etcetera, wherein the aforementioned apparatus comprises a conveyor for the loose products, a treatment unit defining a treatment chamber, means for generating radio frequency electromagnetic radiation, means for applying radio frequency electromagnetic radiation and/or microwaves which act in the treatment chamber or area and designed to affect the loose products transported through the treatment chamber or area, mixing means for the loose products to be treated arranged in the treatment chamber.
