A beverage dispenser for partially frozen beverages includes at least one bowl for storing a beverage product, with a freezing cylinder positioned in the bowl. The beverage dispenser further includes a cooling system for supplying a cooling medium to the freezing cylinder to cool the beverage product when stored in the bowl, along with a dispenser assembly for dispensing the beverage product from the bowl. The beverage dispenser includes an auger which rotates about the freezing cylinder. A driven hub is positioned on and rotates with respect to the freezing cylinder, and the driven hub engages a rear end portion of the auger. A driver hub is positioned inside of the freezing cylinder and is magnetically coupled to the driven hub, such that rotation of the driver hub causes a corresponding rotation of the driven hub, and thus, rotation of the auger.

A granita production machine includes a bowl (2) designed to receive a water solution to be transformed into granita. The bowl (2), which is provided with a cover (3) and a granita dispensing tap (4), surrounds a cooling drum (11), being arranged orthogonally to the bottom (9) of the bowl (2) and crossed by a rotating shaft (13), which is driven around an axis (y) by a first geared motor (41). The shaft (13) carries removing structure to remove crystals of iced solution from the external surface of the cooling drum (11), including a scraping element (15) and a conveying element (16) connected together. A granita stirring vane (22), being rotated around an axis (y′) by a second geared motor (23) housed in the same cover (3) is dependent inside the bowl (2).

摘要:
Apparatus for producing and dispensing an aerated product comprises a mixer which has a first inlet for receiving a fluid, a second inlet for receiving a gas, and an outlet. A relatively long continuous turbulence passage of relatively small cross section has one end positioned to receive the effluent from the mixer outlet and its other end spaced from the mixer outlet so that the effluent is subjected to confined turbulent mixing in the turbulence passage until the fluid product is discharged from the passage other end. If that product is to be cooled, the turbulence passage leads to a cooling area which cools and at least partially freezes the fluid product issuing from that passage. The invention has particular application to the making and dispensing of frozen yogurt and ice cream and allows for the service of individualized fresh portions in a variety of flavors and with little required cleaning.

The invention relates to a method of manufacturing freezing cylinders for ice cream making machines, with incorporated evaporator of the refrigerating circuit, characterized in that it comprises the steps of: forming a helical groove on the outer surface of the freezing cylinder; winding a flat strip of annealed mild steel along said groove in screw-thread fashion, and shrink-fitting a heated cylindrical steel liner on the crests of said thread.

A drum contact freezer system which reduces or eliminates a stagnant layer of refrigerant on an interior surface of the drum freezers is provided. A boiling refrigerant is sprayed into the interior of the drum freezers to scrub an interior surface thereof having the stagnant layer. This scrubbing reduces or eliminates the stagnant layer and thus provides an enhanced rate of heat transfer. The boiling refrigerant is preferably in a temperature range of approximately -100.degree. F. to -40.degree. F. at or near atmospheric pressure. Additionally, the boiling refrigerant may be circulated within the drum freezers by providing troughs on the interior surface thereof to help lift the boiling refrigerant and prolong contact between the boiling refrigerant and the interior surface of the drum freezers to provide a further enhanced rate of heat transfer. The material to be frozen may be provided on an outer surface of the drum freezers using a drop nose feed conveyor, soft sponge rollers, or a sprayer assembly depending upon the type of material to be frozen.
摘要:
In a process for producing composite confection products, comprising a plurality of superimposed confection layers formed from extruded strands, in particular of ice cream, of which at least one is wave-shaped and may overlap itself, the confection layers are extruded on to a conveyor belt and to produce the wave shape the component of movement of the extruded material is greater than the movement of the conveyor belt so that at least a first point of deposition of the leading end of the strand issuing from at least one extrusion nozzle is displaced laterally relative to the vertical movement of the extrusion strand from the outlet to the plane of deposition of the conveyor belt so that the pasty confection material is deposited laterally under its own weight due to a lateral displacement of the center of gravity of the strand, and that the conveyor belt is displaced laterally at the latest when at least one loop comprising at least two superimposed strand sections has been formed.A composite confection product produced according to the process is also described.
