  • Publication number: 20200305382
    Abstract: A separator for separating raw milk into a skimmed milk phase, a cream phase and an ejection phase that comprises solid impurities is disclosed. The separator includes an ejection port arranged at a periphery of the separator to eject the ejection phase. A cyclone is connected to the ejection port to receive and decelerate the ejection phase, and a vessel in fluid communication with an ejection phase outlet of the cyclone to receive and collect the ejection phase from the cyclone. The cyclone includes a port that is open to the atmosphere, such that pressure build-up created in the cyclone when the ejection phase is ejected from the separator into the cyclone is released.

  • Patent number: 8691310
    Abstract: The invention relates to a method of extending the production time of a pasteuriser. The pasteuriser is of the type which includes a plate heat exchanger with a number of sections, of which at least one section consists of regenerative section. The method comprises raising the temperature in the downstream part of the regenerative section to a temperature above 50° C., during a certain predetermined period of time and at regular intervals. During normal production, a part quantity of the product which passes downstream of the regenerative section is shunted past the regenerative section. At the regular intervals and during the predetermined period of time, a part quantity of the product which passes upstream of the regenerative section is shunted past the regenerative section. At the same time, all product passes the downstream part of the regenerative section during the predetermined period of time.

  • Patent number: 8590579
    Abstract: The invention relates to an inlet for a tank which is intended for a liquid food product. The inlet is placed in the side wall of the tank and at the upper end of the tank. The inlet is further designed so that the inflowing product is distributed in fan-shape along the inside of the tank. The application also includes a method of supplying liquid food product to a tank.

  • Patent number: 7975529
    Abstract: A method of discovering leakage in a heat exchanger, wherein the method is carried into effect on an intact heat exchanger which, together with surrounding conduits, is filled with water. The heat exchanger preferably has requisite pressure indicators mounted between each section, as well as requisite shut-off valves. The method comprises applying in each section of the heat exchanger an excess pressure on one side which is enclosed there, while the other side is at normal pressure. The pressure is enclosed during a period of time and is monitored during this period of time.
