A method for extruding a confectionery is provided including supplying a plurality of ingredients to a mixer. The ingredients are mixed to form a confectionery composition in said mixer. Crystals are formed in the confectionery composition while the confectionery composition is in said mixer and the confectionery composition is output from said mixer.

The present invention provides a system and method for producing gummy puffs. The system and method involves utilizing specific raw materials with specific chemical properties, manipulating vapor pressures, a low temperature dehydration process, and continuous freezing and annealing to form the gummy puffs. The gummy puffs produced by the system are dehydrated and have lower moisture content and have enhanced taste and flavors.

A method and apparatus for producing popping candy which is formed in molds. A reactor with one or more trays holds the product and one or more moveable transmission mechanisms and one or more lids provided at each end of the reactor act as inlets and outlets. One or more two way valves regulate and maintain inside pressure of the reactor and cooling and heating mechanisms are provided.

The installation (1) comprises: a vacuum expansion chamber (4), having an inlet (4a) provided with a first gas-tight valve device (5) for receiving a flow of semi-finished pieces (3) prepared starting from a confectionery compound and including particles, such as air bubbles and/or powders, capable of causing an expansion thereof under vacuum, and an outlet (4b). In chamber (4) there is provided a rotating drum (7) having a grille structure, intended to receive and transfer to the outlet (4b) of said chamber (4) a flow of said semi-finished pieces (3), in a controlled period of time sufficient to allow an expansion thereof under vacuum.

A cooling and conveying apparatus (10) under vacuum, at a controlled temperature, has an inlet coupled with the outlet of the expansion chamber (4), and an outlet having an associated second gas-tight valve device (18) for discharging the expanded and cooled confectionery products (3). This apparatus (10) includes at least one cooling and conveying unit (11-14) comprising a conduit under vacuum (11a-14a) in which there is provided a worm conveyor device (11d-14d; 11e-14e) including a flexible spiral screw (11e-14e) intended to cause a displacement of the expanded pieces (3) at a controlled speed.
