摘要： The present invention relates to a method for cooling milk in a milk storage tank of an automatic milking system comprising the steps of (i) measuring an amount of extracted milk by means of a milk flow meter; (ii) determining a cooling need for milk stored or to be stored in said milk storage tank based on said amount of milk; (iii) measuring a quantity indicative of a temperature of an inner surface area of a bottom portion of the milk storage tank; and cooling said bottom portion of said milk storage tank in consecutive periods, such that each period of cooling ( tau 1, tau 3) is followed by a respective period of non-cooling ( tau 2, tau 4), wherein the duration of each period of cooling and/or non-cooling is based on said measured quantity indicative of said inner surface area temperature, and said cooling need. The invention also relates to an arrangement for performing the method.

摘要： A method is provided for eliminating the risk of leakage from a first one to a second one of two fluid systems (123, 124) in an apparatus provided for handling a fluid for human consumption, which comprises a shut-off device including a cavity (122; 154) and a respective valve means (111, 121; 151, 152) connecting the cavity to each of the two fluid systems, each of the valve means being capable of preventing any fluid communication from the cavity to the respective fluid system. According to the method, when the valve means (111, 121; 151, 152) prevent any fluid communication from the cavity to the fluid systems, a fluid is supplied to the cavity (122; 154) and a pressure (P3) is provided in the cavity which is higher than one or each of the respective pressures (P1, P2) 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 means.

摘要： The present invention relates to a system for controlling the cooling of small milk quantities in a cooling tank (4). An agitation pipe (2) extended through a regular milk outlet (26) in a first end wall (6) of said tank is provided, having a nozzle end (32) for introducing incoming/re-circulated milk onto a milk cooling surface (14) at a predetermined position (dp). Said position (dp) being situated (l) between a first end wall (6) and a central part of the tank (4) and laterally displaced (b) relative to the perpendicular central axis of the tank. Said nozzle end (32) is directed towards a second end wall (8) of the tank (4). Agitation is performed by means of said agitation pipe (2) upon demand or when the milk quantity is insufficient for a regular agitator means (27) to work properly.

摘要： A milking plant for milking animals, such as cows, wherein milk collecting means, preferably 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 milk 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 characterised 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.

摘要： The present invention refers to an apparatus (11) and a method for milk filtration and filter regeneration. The apparatus comprises a filter vessel (13); a loose filter material (37) housed within the vessel for filtering out contaminants in the milk; and a grid (31) arranged in front of the milk flow outlet to prevent the loose filter material from leaving the vessel. The vessel includes inner walls (15, 17); a milk inlet (21); a milk outlet (23); a cleaning fluid inlet (23) arranged substantially vertically at the lowermost portion of the vessel, through which a cleaning fluid jet can be injected, and a cleaning fluid outlet (21) arranged at the upper portion of the vessel. The lower portions (17) of the inner walls of the vessel form an angle (alpha) with respect to the horizontal plane, the angle being larger than the angle of repose for the filter material in the cleaning fluid. Thus, the filter material, which is flowed vertically upwards (45) by the cleaning fluid jet, moves substantially radially outwards (45) with respect to the jet to descend downwards (47) and slide back (47) towards the jet by aid of the angled inner wall portions.
