4. Inclusions

At the output of the freezer or low-temperature extruder, a fruit feeder can be integrated into the line. The purpose of this device is to continuously dose and introduce not only solid fragments (dried or candied fruit, caramel chips, mini candies, etc.), but also liquid products (chocolate sauce, various fruit coulis and purées, etc.). This device requires precise dosing of liquid or solid inclusions, taking into account the flow rate of the frozen dessert. Incorporation pumps are volumetric gear pumps which must respect the integrity of the inclusions' shape. To innovate in the visual presentation of the product, grouts are injected through small, possibly rotating nozzles, to produce marbling effects and seduce consumers.
