A device (1) for pasteurizing a mass of foodstuff comprises : a feed (3); a first tube (5), connecting to the feed, of an electrically and magnetically inert material suitable for contact with food; two plate-like electrodes (6,7) which are situated on either side of the first tube and which are connected to an RF power generator, whereby the mass present in the first tube is heated dielectrically in this first tube; a first jacket (10) filled with a heatable first liquid and extending around the first tube; a second tube (11) which connects to the first tube and in which the hot mass is held at practically constant temperature; and a second jacket (13) filled with a heatable second liquid and extending around the second tube for this purpose, at the end of which second tube the hot mass is discharged for further processing, such as cooling, portioning and packaging.
A23L 3/01 - Preservation of foods or foodstuffs, in general, e.g. pasteurising, sterilising, specially adapted for foods or foodstuffs by heating using irradiation or electric treatment using microwaves or dielectric heating
A23L 3/22 - Preservation of foods or foodstuffs, in general, e.g. pasteurising, sterilising, specially adapted for foods or foodstuffs by heating loose unpacked materials while they are progressively transported through the apparatus with transport through tubes
A23B 4/01 - Preserving by heating by irradiation or electric treatment
A device (1) for pasteurizing a mass of foodstuff comprises: a feed; at least one first tube (5), connecting to the feed, of an electrically and magnetically inert material suitable for contact with food; two plate-like electrodes (6,7) which are situated on either side of the first tube and which are connected to an RF power generator (8), whereby the mass present in the first tube is heated dielectrically in this first tube; a first jacket (10) filled with a heatable first liquid and extending around the first tube; and heating means which connect to the first tube and in which the hot mass is held at practically constant temperature; at the end of which heating means the hot mass is discharged for further processing, such as cooling, portioning and packaging.
