The invention relates to a treatment device for treating food products using conditioned treatment fluid, comprising a housing (10), which defines a treatment space (18) and is provided with an inlet (12) for introducing products to be treated into the treatment space, and an outlet (14) for discharging treated products from the treatment space, with the treatment space (18) being in open communication with the environment, a conveying means (16, 20) for conveying the food products from the inlet through the treatment space to the outlet, with the conveying means (16; 20) between the inlet and outlet following a helical conveying path (26) comprising several turns one above the other, circulation means (40) for circulating treatment fluid through the treatment space, conditioning means (56; 57) for conditioning the treatment fluid.
Treatment device for treating food products using conditioned treatment fluid, comprising a housing, which defines a treatment space and is provided with an inlet for introducing products to be treated into the treatment space, and an outlet for discharging treated products from the treatment space, with the treatment space being in open communication with the environment, a conveying means for conveying the food products from the inlet through the treatment space to the outlet, with the conveying means between the inlet and outlet following a helical conveying path comprising several turns one above the other, circulation means for circulating treatment fluid through the treatment space, conditioning means for conditioning the treatment fluid, with at least one of the inlet and outlet comprising a duct extending through the housing and being positioned in such a manner that, during operation, there is essentially no pressure difference between an end of the duct in the treatment space and an end of the duct outside the housing.
Assembly of several treatment devices for treating food products with conditioned treatment fluids, comprising a first treatment device and at least one additional treatment device, in which the first treatment device comprises a first housing which defines a first treatment space and is provided with a first inlet for introducing products to be treated into the first treatment space, and a first outlet for discharging treated products from the first treatment space, with the first treatment space being in open communication with the environment, a first conveying means for conveying the food products from the first inlet through the first treatment space to the first outlet, with the first conveying means between the first inlet and first outlet following a first helical conveying path comprising several turns one above the other, first circulation means for circulating a first treatment fluid through the first treatment space, first conditioning means for conditioning the first treatment fluid, and with a second treatment device comprising a second housing which defines a second treatment space and is provided with a second inlet for introducing products to be treated into the second treatment space, and a second outlet for discharging treated products from the second treatment space, with the second treatment space being in open communication with the environment, a second conveying means for conveying the food products from the second inlet through the second treatment space to the second outlet, second conditioning means for conditioning a second treatment fluid, with either the first outlet of the first treatment device and the second inlet of the second treatment device, or the second outlet of the second treatment device and the first inlet of the first treatment device being connected to one another by a connecting duct which extends through the first and the second housing with the ends of the connecting duct being positioned in the first and second treatment space, respectively, in such a manner that there is essentially no pressure difference between the end of the connecting duct in the first treatment space and the end of the connecting duct in the second treatment space during operation.
