Abstract: A three-way antimix valve (1) for a pourable food product packaging machine, the valve having a casing (2) in turn having a lateral wall (4) which defines a cavity (6) having an axis of symmetry (A) and communicating with a bottom drain opening (7), and has three gates (10, 11, 12) spaced 90° apart; and a rotary shutter (3) housed inside the cavity (6), rotating about the axis (A), and having a lateral surface (20) in which are formed two openings (22, 23) spaced 90° apart and communicating with each other via an inner passage (24) for connecting respective pairs (10,12; 11,12) of gates in two respective work positions (a, b) of the shutter (3); the casing (2) has two recesses (17, 18) spaced 90° apart and each located in an intermediate position between a respective pair (10,12; 11,12) of gates; and the shutter (3) has four recesses (25, 26, 27, 28) spaced 90° apart, and one (25) of which is located between the two openings (22, 23) to connect the passage (24) and the three gates (10, 11, 12)

Abstract: The invention relates to a double-seat valve, particularly for aseptic applications, having at least two line connections (3, 4, 7), between which two annular valve seats (11, 12) are disposed coaxially with one another and in series, having two closers (8, 9), which are axially closable independently of one another and which in the closed state cooperate sealingly with the valve seats (11, 12) and between them enclose a hollow chamber (34), and having at least one cleaning connection (35, 36), discharging into the hollow chamber (34), for introducing a cleaning medium.

Abstract: A method of carrying out quality control of a packaging container or packaging container blank comprises providing a package or blank having one or more poles (12) for interconnection with electric quality control equipment (24). The packaged product (20) will be directly or indirectly electrically accessible, whereby both the quality of the packed product and the tightness of the surrounding packaging container (1) may be determined in a rational and partly automated manner. This is of particular importance in the production of aseptic packaging containers for, for instance, ready-made, heat-treated soups or similar foods.

Abstract: In packing machines which have a filling pipe with two or more ducts, a rinsing of the filling pipe with cleaning fluid may lead to only one duct being properly cleaned. In order to prevent this, an arrangement is provided on packing machines which have a coupling part provided with valves with passages which are coupled in series with respective ducts in the filling pipe. The valve is adapted so that it is acted on towards the closed position by the cleaning fluid flowing past and thus limits the flow through the one duct so that the other duct too is assured of an adequate flow for effective cleaning.

Abstract: Filters for the supply of inert gas to packing machines are sterilized by passing steam and sterile air through the filters via a number of ducts, valves and governors. A simple method for achieving the sterilization is obtained by sterilizing the filter jointly with the antiseptic packing machine which may be done by connecting one side of the filter in series to the circulation system of the machine for sterilization by a chemical sterilizing agent. In this way the abovementioned arrangement is simplified considerably in that a large number of valves and ducts becomes superfluous.
