Patent number: 8286653Abstract: A method is provided for eliminating the risk of leakage from a first one to a second one of two fluid systems in an apparatus for handling a fluid for human consumption, with a shut-off device including a cavity and a respective valve element connecting the cavity to each of the two fluid systems, each valve means being capable of preventing any fluid communication from the cavity to the respective fluid system. When the valve element prevents any fluid communication from the cavity to the fluid systems, a fluid is supplied to the cavity and a pressure is provided in the cavity which is higher than one or each of the respective pressures in the two fluid systems, thereby eliminating the risk of leakage from a first one to a second one of two fluid systems in case of failure of the valve element.Type: GrantFiled: February 5, 2008Date of Patent: October 16, 2012Assignee: DeLaval Holding ABInventors: Magnus Lidman, Staffan Persson

Patent number: 8191507Abstract: The invention relates to a solution for cleaning a milking plant, which includes a milk line system (MLS), connectable to a collecting means, and is adapted to deliver milk that has been withdrawn from animals to a milk storage means (250). The milking plant also includes milk storage valve means (100; 235, 240), arranged between the milk line system (MLS) and the milk storage means (250). The valve means (240) are selectively adjustable to prevent fluid communication between the milk line system (MLS) and the milk storage means (250) during cleaning of the milk line system (MLS). Moreover, the valve means (100; 235, 240) are associated with a monitoring arrangement (275, EPS), which is adapted to determine an amount of leakage through the valve means (100; 235, 240) during the cleaning of the milk line system (MLS), and produce a valve health status signal (Sv) reflecting the amount of leakage. Hence, the functionality status of the valve means (100; 235, 240) may be qualitatively evaluated.Type: GrantFiled: October 29, 2007Date of Patent: June 5, 2012Assignee: DeLaval Holding ABInventors: Staffan Persson, Magnus Lidman

Patent number: 6852172Abstract: A milking plant for milking animals, such as cows, wherein milk collecting means, prefeably in the form of teat cups, are attached to the teat of the animal whereafter milk is taken from the animal by use of vacuum. The milk is transported by a milk line system (31) to milks storage means comprising a cooling tank (30). For cleaning purposes the milk line system from each milk collecting means can be shut off from the milk tank by valve means (32) in order for separate cleaning of the milk line system. The invention is characterized by preventing any possible leakage of detergent from a cleaning fluid to the milk that has been collected in the milk tank, by providing a pressure difference between the two fluids. The pressure difference between the fluids is preferably achieved by connecting the cleaning fluid to the vacuum supply (4) of the milking plant.Type: GrantFiled: September 12, 2000Date of Patent: February 8, 2005Assignee: DeLaval Holding ABInventor: Magnus Lidman

Patent number: 5928702Abstract: Continuous production of milk with a predetermined fat content wherein whole milk is divided into a cream fraction and a skim milk fraction in a centrifugal separator. A part of the cream fraction is remixed into the skim milk fraction in order to obtain a mixed fraction of milk with desired fat content. The whole flow of cream fraction which has been obtained from an outlet from the centrifugal separator is remixed with a flow of skim milk fraction from a second outlet from the centrifugal separator by way of a valve in the outlet for cream fraction during a certain period. During a second intermediate period the whole flow of cream fraction is discharged by the valve for separate collection. The periods mentioned above are so short that the fat content and the flow per time unit of the mixed fraction may be regarded as homogenous.Type: GrantFiled: January 16, 1995Date of Patent: July 27, 1999Assignee: ALFA Laval Agri ABInventors: Magnus Lidman, Guido Marzotto

Patent number: 5207177Abstract: A pulsator has two valve devices (1, 2), each of which is adapted to alternately subject a pulsation space to two different pressures. In order to avoid the two valve devices (1, 2) from disturbing each other during the alternations between the two pressures a third valve device (23) is arranged, for closing communication between one of the valve devices and the lower one of said two pressures, when the other valve device is operated to alternate the pressure in the pulsation space from the lower one to the higher one of said two pressures.Type: GrantFiled: January 7, 1992Date of Patent: May 4, 1993Assignee: AB ManusInventor: Magnus Lidman

Patent number: 4997662Abstract: When continuously heat treating a liquid the flow of which varies, incoming liquid is preheated by already heated liquid and is then heated to a predetermined temperature-time-effect by a medium giving off heat in a second step. The flow of incoming liquid is sensed and controlled by a pump (1) with a variable capacity. The amount of heat needed to obtain the desired heating effect is influenced by a control unit (9). The heating effect is adjusted to the liquid flow by increasing/decreasing the temperature of the medium giving off heat or increasing/diminishing the flow of this medium from a heat store (6).Type: GrantFiled: November 29, 1989Date of Patent: March 5, 1991Assignee: Alfa-Laval ABInventors: Magnus Lidman, Kare Eilertsen, Alf Karlsson
