Abstract
A distribution unit for milk samples includes a flow passage, a valve controlled milk inlet port through which milk is delivered to the flow passage, a pump port through which a sampling pump communicates with the flow passage, and at least two valve controlled milk sampling outlet ports through which milk samples are delivered from the flow passage to a respective milk sample analyzing unit. The flow passage has a longitudinal extension between a first end and a second end, and the milk sampling outlet ports are connected to the flow passage in positions located between the connection position of the milk inlet port and the connection position of the pump port.
Claims11
A distribution unit (5) for milk samples, comprising:
- a first block element having a flow passage (19) defined by a first end (19a), an opposite second end (19b), and a longitudinal extension running therebetween, the longitudinal extension having a plurality of ports extending transversally from the longitudinal extension and each in fluid communication with the flow passage;
- a second block element, attached to the first block element and comprising a plurality of spaces;
- and
- a plate-shaped elastic gasket (20) having a first side that forms a longitudinal side surface of the flow passage (19) of the first block element and a second opposite side in contact with valve bodies located in the spaces of the second block element,
- a first of said plurality of ports constituted by a valve controlled milk inlet port (p1) through which milk is delivered to the flow passage (19),
- a second of said plurality of ports constituted by a pump port (p9) through which a sampling pump communicates with the flow passage (19), and
- a third and fourth of said plurality of ports constituted by, respectively, two valve controlled milk sampling outlet ports through which milk samples are delivered from the flow passage (19) to respective milk sample analyzing units,
- wherein said milk sampling outlet ports are connected to the flow passage (19) in positions located between the connection position of the milk inlet port (p1) and the connection position of the pump port (p9).
