Abstract

Automatic machine for manufacturing ice creams consisting of a creamy mass or ice block joined to a stick or a cone of edible biscuit material, comprises elastomer moulds deformable under cold conditions to assume two symmetrical concave and convex configurations, and the means for accomplishing said deformation.

Claims

1. Process for manufacturing ice cream of the type consisting of a hardened creamy mass and in which a support stick is embedded, comprising the following operations in succession:

feeding one or more different types of creamy material by known proportioning devices into suitable deformable elastomer recesses,

inserting a stick into said recesses in succession,

introducing said recesses into a chamber at very low temperature of the order of 40°

- 45°

C below zero, for a time of approximately 40 - 46 minutes;

withdrawing said recesses from said chamber and feeding them inverted to a suitable discharge station;

deforming said recesses by acting on them externally from above with a suitable pressure to make them assume an inverted symmetrical configuration, with the consequent expulsion of the hardened creamy mass;

subsequently deforming said recess in the opposite direction to make them assume their initial configuration.

2. Process for manufacturing ice cream of the type consisting of a hardened creamy mass and which is supported and stably fixed at the top of a hollow cone of edible biscuit material, comprising the following operations in succession:

feeding one or more different types of creamy material by known proportioning devices into suitable deformable elastomer recesses;

making a hollow cone of edible biscuit material fall onto said recesses;

introducing said recesses into a chamber at very low temperature of the order of 40°

- 45°

C below zero, for a time of approximately 40 - 46 minutes;

withdrawing said recesses from said chamber and feeding them inverted to a suitable discharge station;

deforming said recesses by acting on them externally from above with a suitable pressure to make them assume an inverted symmetrical configuration, with the consequent expulsion of the hardened creamy mass;

subsequently deforming said recesses in the opposite direction to make them assume their initial configuration.

3. Automatic machine for manufacturing blocks of ice cream and the like comprising a refrigerated chamber, a conveyor which travels along part of its path of travel in the open air and part of said path within said chamber, transverse members on said conveyor, each consisting of a plate of elastomeric material defining recesses having walls thinner than said plate, feed means for a creamy material, spray means for material in aqueous suspension and feeder means for a wooden stick or cone of edible material upstream of said refrigerated chamber, and means located on opposite sides of said conveyor downstream of the refrigerated chamber for causing said recesses to assume an inverted configuration symmetrical with respect to their initial configuratiion and then returning them to their initial configuration.

4. Automatic machine for manufacturing blocks of ice cream and the like comprising a refrigerated chamber, a conveyor which travels along part of its path of travel in the open air and part of said path within said chamber, transverse members on said conveyor, each consisting of a plate of elastomeric material defining recesses having walls thinner than said plate, means located on opposite sides of said conveyor downstream of the refrigerated chamber for causing said recesses to assume an inverted configuration symmetrical with respect to their initial configuration and then returning them to their initial configuration and a transverse conveyor below the means for causing said elastomeric recesses to assume an inverted configuration, said transverse conveyor comprising cavities into which said means cause said blocks to fall when said recesses are deformed.
