Abstract: A process and apparatus to subject a pumpable mass of candy stock to heat, by conveying the candy stock to be heated through a heating coil (7) of a steam heated heat exchange (6). A fluid medium is added to the candy stock upon entry into the heat exchange (6) and as the candy stock leaves the heat exchanger it is guided into a receiving tank (13) which allows the medium to escape the candy stock. The medium to be added to the candy stock is steam, such that by the condensation of the steam the temperature of the candy stock is raised at least into the vicinity of its boiling point, preferably above its boiling point.

Abstract: A method of continuously producing hard-candy masses from an aqueous solution of starting ingredients by boiling and condensing the solution, subjecting it to a vacuum, condensing it further and cooling it, adding flavorings, dyes, etc., and finally cooling it again and shaping it into candy. The starting ingredients are sugar substitutes and the solution is subjected to a vacuum as early as while it is being boiled and while it is being condensed and will accordingly have a temperature that is low enough for conventional flavorings, a viscosity that is high enough for conventional cooling and tempering, and a low enough residual-water content.

Abstract: A method for producing an aerated confectionery foam from a sugar solution and a foam-promoting solution. The aerated confectionery foam is produced batch by batch using a boiler and a beater. The sugar solution is boiled in the boiler and transferred to the beater. The aerated confectionery foam is formed from the foam-promoting solution and the boiled sugar solution, and removed from the beater through pressure application. The foam-promoting solution is beaten in a vacuum either by itself or along with the boiled sugar solution. The pressure in the beater during the beating procedure is sub-atmospheric. The aerated confectionery foam is produced with small and finely distributed bubbles. The pressure during beating the foam-promoting solution differs from the pressure at which the aerated confectionery foam solidifies.

Abstract: An arrangement for batchwise production of aerated sugar masses, in which a separate cooker is connected to a pressure beating machine for boiling a sugar solution to be aerated at atmospheric pressure without subsequent vacuum treatment in the cooker. The boiled solution is transferred into the pressure beating machine where it is vacuumized by an additional boiling under vacuum to obtain a substantially viscous sugar mass. The solution in the pressure beating machine is then mixed after vacuumizing with added whipping agent solution. Thereafter, the mixed solution is beat in the pressure beating machine, and compressed air is added to produce an aerated sugar mass that consists substantially of cooked and vacuumized sugar solution, whipping agent solution, and air. The vacuumizing and the beating are carried out only in the pressure beating machine. The vacuumizing reduces the water content of the sugar mass through vaporization.

Abstract: Method of and device for heat-treating candy masses with heat exchangers. A gas, compressed air for instance, is injected subject to regulation of its pressure and volume into the mass before the latter enters the heat exchanger. The result is a regulated turbulence inside the heat exchanger that makes the heat transfer more efficient.

Abstract: The invention concerns a method for the batchwise production of aerated sweets in a pressure-beating machine, wherein--according to the invention--the sugar mass to be aerated is boiled with the omission of an underpressure treatment, is conducted to the pressure-beating container and brought in this to the required residual water content and the required further processing temperature at underpressure before the beating, whereupon a beating of the mass takes place in the pressure-beating machine.

Abstract: The invention relates to a method for continuously processing boiled and vacuumized confectinery masses, especially bonbon masses like hard and soft caramel masses, fondant masses, etc., in a mixer, which the mass being processed travels through while simultaneously being supplied with compressed air, whereby the inside of the mixer is kept pressurized in accordance with the invention by regulating the mixer outlet.

Abstract: The invention concerns a method of constructing a plastic rope used in the manufacture of hard bonbons with a stratified core that is made out of multiple layers of plastic sugar and plastic filling. The ropes are brought independently of one another to a predetermined thickness and width. Plastic filling is constantly applied to at least one of the ropes and rolled into it from the side in such a way as to produce a tube that is closed into itself and that, after being dimensioned, is pushed along laterally into the rope of plastic coating with the edges overlapping in such a way that they adhere together. The accordingly prepared ropes are then introduced together into a rope shaper (conical roller), stretched farther horizontally if necessary, and supplied to the cutting machine.
