Continuous machines for the instantaneous production of whipped cream

Claim 2

A machine according to claim 2, wherein the said core and the said bore of the emulsifying homogenizer are conical, at least in their middle section.

Claim 3

A machine according to claim 3, wherein the conical bore of said emulsifier shell is smooth while the surface of the corresponding conical core is provided with annular ribs; spring means in the larger end of said shell pressing the corresponding wider head end of the core against the walls of the shell bore, the whole being so arranged that when a mixture of liquid cream and air is pumped under pressure into said inlet of the emulsifier, it shifts axially said core, against the action of said spring means, and slightly spaces said annular ribs from the corresponding shell bore, thus generating a plurality of subsequent annular slits of increasing diameter and flow area.

Claim 4

A machine according to claim 4, wherein the said bore of the shell is conical in its intermediate section, but is cylindrical at its ends, and the corresponding core has cylindrical end sections, provided with annular ribs composed of separate segments, leaving between subsequent segments a narrow passage, the narrow passages of each segment being not in alignment with the passages of adjacent segments; the whole so as to permit the flow of the cream-and-air mixture at the inlet and outlet ends, through the said narrow passages, and in the intermediate conical section, between the ribs on the conical part of the core and the corresponding shell walls.

Claim 5

A machine according to claim 1, wherein the conical bore of said shell is substantially smooth, while the surface of the corresponding conical core is provided with annular ribs, means being provided for slightly spacing said ribs from the corresponding surface of the conical bore of said shell.

Claim 6

A machine according to claim 1 wherein the said bore of the emulsifier shell is conical and the corresponding core comprises a supporting rod, pairs of washerlike discs either of which Has a central bore fitting exactly on said rod, while its diameter is substantially less than the diameter of the corresponding section of the shell bore and the other of which discs has a diameter which corresponds to the diameter of the corresponding shell section, when the core is exactly mounted, while its central bore is substantially wider than the section of the said supporting rod, whereby either of the contacting faces of the discs present fine indentations leaving between the adjacent disc faces a plurality of intersecting very fine flow slits, by passing through which the said mixture is finely emulsified while its volume may increase by proceeding from the central part of the discs towards their periphery.

Claim 7

A machine according to claim 1, wherein the said emulsifier comprises a shell having a cylindrical bore and a plurality of sleevelike core members concentrically arranged in said shell bore and fitted upon a central tube acting as feed tube for the mixture to be emulsified and as supporting rod; rough or indentated surfaces on said concentrical core members and on said central tube for forming between adjoining cylindrical surfaces a large number of fine intersecting slits and overflow passages at the ends of alternate core sections for permitting the flow of the mixture from any one of the slitted passages between each pair of adjoining cylindrical surfaces and the subsequent passage, whereby said subsequent cylindrical passages, being of greater diameter, permit a stepwise increase of the flow area of cream-and-air emulsion.
