Systems and methods for preparing and dispensing food contents, typically molten chocolate. In one aspect, a method for treating chocolate includes placing a quantity of chocolate defining a chocolate surface in a vacuum chamber, heating the quantity of chocolate to a temperature sufficient to substantially liquefy the quantity of chocolate, decreasing the pressure of the vacuum chamber to a predetermined pressure, wherein the chocolate surface is subjected to a partial vacuum and wherein substantially all trapped gases are outgassed from the quantity of chocolate, holding the pressure of the vacuum chamber at the predetermined pressure for a predetermined period of time, and increasing the pressure of the vacuum chamber to room pressure. The chocolate comprises cacao, cacao butter, and sugar. During treatment, the temperature of the chocolate is maintained sufficiently high to maintain the chocolate as a liquid.

The food dispenser is a configured for use with a viscous foodstuff. The food dispenser is an extrusion device. The food dispenser extrudes the viscous foodstuff. The food dispenser is a temperature controlled device. The food dispenser maintains the viscous foodstuff at a set temperature during the extrusion of the viscous foodstuff. The food dispenser comprises a piping gun, a heating element, and a thermal control. The piping gun contains and extrudes the viscous foodstuff. The heating element heats the viscous foodstuff contained within the piping gun. The thermal control turns the heating element on and off to control the temperature of the viscous foodstuff during extrusion.

Content containers and vessels, one aspect including a deformable fluid-tight container shell defining an internal volume and separating the internal volume from an external environment; a room-temperature semi-solid content contained within the internal volume; and a valve operationally connected to and disposed at least partially without the deformable container shell; where the semi-solid content is a hydrophobic matrix with at least partially emulsified hydrophilic components; where the container shell is substantially fluid-tight; where the valve has open state(s) and a closed state; where the valve may be actuated between the open state(s) and the closed state; where the valve is self-cleaning; where during the open state(s), the internal volume is in fluidic communication with the external environment; where during the closed state, the internal volume content cannot fluidically communicate with the external environment; and where the content remains moisture-stable while the valve is in the closed state.

Systems for dispensing chocolate, in one aspect including a generally fluid-tight exterior housing with first volume; a vertical support member; a base support member; a dispenser guiding member within the first volume; an extruder connection member extending through the housing and having a first end within the housing and a second end outside of the housing, defining a pivot axis; an extruder member connected to the first end; a lever connected to the second end; at least one extruder guide member within the first volume and connected to the extruder member; and at least one extruder guide rail connected to the housing within the first volume and capable of receiving the at least one extruder guide member; and where manual actuation of the lever pivots the extruder member in cooperation with the at least one extruder guide member.

Methods for treating and preparing chocolate. In one aspect, a method includes heating a quantity of chocolate to a temperature of about 46 degrees Celsius; decreasing the pressure of in a pressure-controllable environment to about 25 Torr; holding the pressure of the pressure-controllable environment at about 25 Torr for a first predetermined period of time; decreasing the pressure of the pressure-controllable environment to about 5 Torr; and holding the pressure of the pressure-controllable environment at about 5 Torr for a second predetermined period of time. Other aspects include ceasing heating the quantity of chocolate; decreasing pressure occurs at an average rate of about 150 Torr per minute; decreasing pressure occurs at an average rate of about 4 Torr per minute; and others.

Apparatus and systems for melting and liquefying chocolate. In one aspect, a system includes a generally fluid-tight exterior housing defining a first volume; a bulkhead positioned within the housing and dividing the first volume into separate second and third volumes; at least one vertical support member operationally connected to the exterior housing; a base support member operationally connected to the vertical support member; a dispenser guiding member disposed within the first volume and operationally connected to the exterior housing; and a heating element in thermal communication with the first volume, wherein energization heats the first volume to 37 to 46 degrees Celsius. Other aspects include where the liquid chocolate contains less than 3% water; where the liquid chocolate is solid at room temperature; a multiple pivot hinge; and a noninterfering interdigitating hinge.

A three dimensional printer extruder, comprising: a heating member comprising two or more heating member tunnels, each tunnel adapted for receiving a filament; and a nozzle comprising: a single extrusion aperture for extruding material; and two or more nozzle tunnels each connecting to one of the two or more heating member tunnels, and each having an output end at most 1.5 mm from the single extrusion aperture, wherein each filament is melted in a separate space comprising a heating member tunnel and a corresponding nozzle tunnel.

An apparatus (1) for producing cores (33) of a fat-containing confectionery mass includes a molding apparatus (20) and a separate cooling apparatus (5). The molding apparatus (20) is cooled and serves to mold the cores (33). The molding apparatus (20) includes two molding rollers (23, 24) including a multitude of impressions (25). The molding rollers (23, 24) are driven in opposite directions. The impressions (25) hold the liquid confectionery mass flowing into the impressions (25) to form the cores (33). The cooling apparatus (5) includes a cooling roller (6) and is arranged upstream of the molding apparatus (20).
