  • Publication number: 20130177679
    Abstract: A method for adjusting or controlling the temperature of water released for product pasteurization, by taking into consideration the heat transfer into the products for the control of the water temperature. Further, a method for adjusting or controlling the water temperature for the water released for product pasteurization in several superimposed decks, by taking into consideration the water temperature in at least one deck located below the upper deck for the control of the water temperature. Also, corresponding pasteurization tunnels as well as a pasteurization tunnel with at least three superimposed decks, where the water for at least three decks is released to the products in the uppermost deck.

  • Patent number: 7644654
    Abstract: A continuous flow pasteurization apparatus for a liquid product includes a pasteurization area divided into plural pasteurization zones, each with a connection for heating and/or cooling the product, so that if production stops, it is possible to hold the temperature below the pasteurizing temperature. Upon restarting, the product is reheated to a temperature close to the pasteurizing temperature. The apparatus provides for the control and monitoring of pasteurization units (PU's).

  • Patent number: 6647867
    Abstract: A pasteurizer (1) comprising an endless circulating transport conveyor (3) guided around deflection rolls (7, 8) and used for transporting through the pasteurizer (1) the products (18) to be pasteurized, and having a feed conveyor (5) and/or a discharge conveyor (9) oriented essentially transversely to the conveying direction of the transport conveyor (3) and having a smaller width than the transport conveyor (3), feed conveyor (5) and/or discharge conveyor to and away from the respective end face of the transport conveyor (3), and a transfer surface (4, 19) for bridging a distance between the conveying surface(s) of the feed conveyor (5) and/or of the discharge conveyor (9) and the conveying surface of the transport conveyor (3). The feed conveyor (5) and/or the discharge conveyor (9) is arranged so close to the respective end face of the transport conveyor (3) that the lateral boundary (K) thereof, which face the transport conveyor (3), is arranged above the contour of the respective deflection roll (7, 8).

  • Patent number: 5772958
    Abstract: The method and the apparatus according to the invention relate to pasteurization of products in a tunnel pasteurizer. In the application of heating systems comprising water/steam heat exchangers in the zones for heating of sprinkling water, the pipelines and the valves for controlling the water and the steam become very complex and vulnerable, and the number of analog valves for steam become equal to the number of heat exchangers as a minimum. Leakages in analog valves for steam are frequent after some time in operation. According to the invention this problem is eliminated in that hot water is taken out under low pressure from a heating source (7) comprising a heat-insulted storage tank and a shared source of heat, where the water is circulating constantly, said hot water being supplied in a controlled amount directly to each zone (14b, . . .
