Abstract
Abstract The installation comprises a static mixer (1) connected to receive yoghurt from a yoghurt store (4) and a flavoring from a selected flavoring store (8 to 10). The amount of yoghurt and flavoring dispensed is measured by appropriate metering pumps (11 to 14). The static mixer has a bottom outlet (1a) under which a beaker (20) is placed to receive a portion of flavored yoghurt. The beaker stands over a waste funnel (19) to catch drips and spills. A wash tank (22) is provided together with various feeds for rinsing and/or cleaning materials (27 to 28). The wash tank is connected via a pump (33) and a duct (31) to a spray head (34) in the yoghurt store (4). A thorough automatic rinse-wash-rinse cycle can be performed, whenever necessary. The rinse cycles are preferable open circuit cycles, and the wash cycle is preferably a closed circuit cycle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
274 words
An installation for automatically dispensing, upon request, individual portions of drinking yoghurt in selected flavors, said installation comprising: a store of liquid yoghurt having duct means leading therefrom and yoghurt control means for causing a portion of yoghurt to flow from said store; at least one flavoring store having respective flavoring duct means leading therefrom and respective flavoring control means for causing a portion of flavoring to flow from said at least one flavoring store; a static, free flow mixer comprising a body which defines an inside chamber having an inlet terminating therein and connected to the yoghurt store via said duct means and said yoghurt control means, a plurality of inlet ducts connected to respective ones of the at least one flavoring store via respective ones of said flavoring duct means and said flavoring control means, said inside chamber further having a plurality of outlet orifices, wherein said inlet, said inlet ducts and said outlet orifices are arranged so that the yoghurt and flavoring entering the chamber are mixed together before leaving the chamber through one of said outlet orifices; means for supporting a beaker in a position in which it can receive the yoghurt and flavoring mixture leaving the outlet orifices of said mixer; and a device for cleaning the installation, said device comprising a wash tank having an outlet connected to said yoghurt store and an inlet connected to the outlet orifices of the mixer, means for supplying said wash tank in a controlled manner with cleaning material, means for pumping said cleaning material from the tank to the yoghurt store, and means for connecting the tank to waste disposal means.
Claim 2
Dependent Claim
274 words
An installation for automatically dispensing, upon request, individual portions of drinking yoghurt in selected flavors, said installation comprising: a store of liquid yoghurt having duct means leading therefrom and yoghurt control means for causing a portion of yoghurt to flow from said store; at least one flavoring store having respective flavoring duct means leading therefrom and respective flavoring control means for causing a portion of flavoring to flow from said at least one flavoring store; a static, free flow mixer comprising a body which defines an inside chamber having an inlet terminating therein and connected to the yoghurt store via said duct means and said yoghurt control means, a plurality of inlet ducts connected to respective ones of the at least one flavoring store via respective ones of said flavoring duct means and said flavoring control means, said inside chamber further having a plurality of outlet orifices, wherein said inlet, said inlet ducts and said outlet orifices are arranged so that the yoghurt and flavoring entering the chamber are mixed together before leaving the chamber through one of said outlet orifices; means for supporting a beaker in a position in which it can receive the yoghurt and flavoring mixture leaving the outlet orifices of said mixer; and a device for cleaning the installation, said device comprising a wash tank having an outlet connected to said yoghurt store and an inlet connected to the outlet orifices of the mixer, means for supplying said wash tank in a controlled manner with cleaning material, means for pumping said cleaning material from the tank to the yoghurt store, and means for connecting the tank to waste disposal means.
Claim 3
Dependent Claim
41 words
An installation as defined in claim 1, wherein said device for cleaning the installation further comprises a manifold having an inlet connected to the wash tank and having at least one outlet connected to respective ones of said flavoring duct means.
Claim 4
Dependent Claim
84 words
An installation as defined in claim 1, wherein said mixer body further comprises two circularly symmetrical parts which are releasably secured one above the other, the first of said parts defining a recess having a flared surface leading to a cylindrical surface and an opening, said inside chamber being formed when the second of said parts, a closure member, is applied to the opening of the recess, said second part comprising a central conical projection extending into the inside chamber coaxial with said opening.
Claim 5
Dependent Claim
60 words
An installation as defined in claim 3, wherein said inlet comprises an axial bore in said first part, opening into the recess, coaxial with and opposite the apex of the conical projection, and said inlet ducts comprise angular bores distributed around said axial bore and opening into the flared surface of the recess opposite the surface of the conical projection.
Claim 6
Dependent Claim
33 words
An installation as defined in claim 4, wherein said outlet orifice comprise sloping bores disposed in said second part around the conical projection, each outlet orifice being substantially diametrically opposite an inlet duct.
Claim 7
Dependent Claim
