Description

PROCESS FOR THE DEVELOPMENT OF SOLID CARAMELS AND TABLETS Description of the invention The present invention relates to a process for the production of a vitreous smelting of a mixture of sweeteners. The elaboration of sugary doughs for confectionery purposes through an extrusion process is known. DE 24 61 543 C2 describes a process of this kind in which glucose syrup and crystallized sugar are introduced into a twin-screw extruder, and this mixture is kneaded under high temperature and high pressure, expanded and compressed. A decrystallized molten sugary mass is obtained, which can be used for the production of, for example, solid candies. US Pat. No. 5,742,733 discloses a process for the production of a vitreous foundry in which a sweetener is introduced into a twin screw extruder, the sweetener is melted and conducted through adjustable coils. It is described that by means of certain temperatures and the adjustment of certain pressure conditions, adjustable by means of a pressure valve, a vitreous smelting can be obtained. The processes described suffer from the disadvantage that the vitreous smelting obtained has comparatively high temperatures when leaving the extruder, it being therefore necessary to cool it on correspondingly long cooling bands. This requires a greater expenditure on appliances and a larger construction space of the chiller bands, as well as longer cooling intervals. In addition, the incorporation of flavors and active substances must be carried out at elevated temperatures, which in many cases is detrimental to the stability of the flavors and active substances incorporated. Accordingly, the technical problem on which the invention is based consists in providing a process for the production of a vitreous smelting suitable for confectionery purposes, preferably free of sugar, which overcomes the aforementioned disadvantages, which in particular results in a product easily elaborable. The technical problem on which the invention is based is solved by providing a process for the production of a vitreous smelting, preferably free of sugar, of a mixture of sweeteners, wherein the mixture of sweeteners is introduced into the intake zone of an extruder , in particular of a twin-screw extruder, is then extruded in a melting zone under elevated temperature, in a subsequent depression zone under reduced pressure and elevated temperature and in a subsequent cooling zone under reduced temperature, and a vitreous foundry. In other words, the process according to the invention leads to the obtaining of a vitreous smelting which, when leaving the extruder, has a lower temperature than the temperature prevailing in the melting zone, and consequently it can be cooled substantially more rapidly on strips of shorter cooling. It is also possible to incorporate aromas and / or active substances in the cooling zone, in particular pharmaceutical active substances at lower temperatures. Naturally, it is also possible to incorporate the flavors and / or the active substances in the sweetener mixture or in the sweetener before introducing it into the intake zone, if the flavors or the active substances are stable at the temperature. It is possible to dispense with the use of what are known as "in-line mixers", which are commonly used for this purpose in traditional extrusion processes. The process according to the invention is also advantageous in that the expense in apparatuses is comparatively modest, in particular in the assembly of the screw extruder. A screw extruder that can be used in accordance with the invention does not require adjustable coils or helical elements that regulate the flow of extrusion dough, and in commerce it can be obtained through the company Togum. Within the context of the present invention, a sweetener is a substance with properties that produce a sweetness sensation, which according to the specific form of its implementation finds application in foods, stimulants, drugs or the like, and which can serve as a vehicle or additive for active substances of pharmaceutical activity, flavors, flavors, flavorings or dyes. In a particularly convenient manner, the mixture of sweeteners used for the process according to the invention contains 100% of the sweeteners listed below, or a mixture of at least two of these sweeteners. However, it can also be envisaged that the sweetener mixture only contains 1-99%, preferably 50-95% of the sweeteners listed below, and additionally has flavors, active substances, minerals, salts, vehicles and substances of filling, for example polymers. The sweetener may be inulin, invert sugar, a 1: 1 mixture of 6-0-aD-glucopyranosyl D sorbitol (1.6-GPS) and 1-0-aD-glucopyranosyl D mannitol (1.1-GPM) known through the ED 25 20 173 Al, a sweetener composed of 1,6-GPS, 1,1-GPM, 1-OaD-glucopyranosyl D sorbitol (1.1-GPS), mannitol, sorbitol and oligosaccharides described in EP 0 625 578 Bl, polydextrose, Hydrolyzed starch hydrated and not hydrated, a sugar alcohol, a monosaccharide or disaccharide as well as a polysaccharide. As monosaccharide or disaccharide, xylose, ribulose, glucose, mannose, fructose, isomaltose, isomaltulose, galactose, sucrose, maltose and the like are particularly taken into account. As sugar alcohol sorbitol, xylitol, mannitol, galactitol, maltitol, 1,6-GPS, 1,1-GPS, 1,1-GPM or the like are taken into account. In the context of the present invention, an intake zone of an extruder is understood to be that zone of the extruder into which the mixture of sweeteners to be extruded is introduced. By melting zone is known that zone of the extruder in which the melting and crystallization of the sweetener mixture used takes place at an elevated temperature. By zone of depression is known that zone of the extruder in which the extrusion takes place at a reduced pressure. By cooling zone is known that zone of the extruder in which the heated extruded mass (melting) is gradually cooled during the melting process. The process according to the invention leads to a cooled vitreous smelting which is conveniently present in a stamped form. In a particularly preferred embodiment of the invention, a temperature of 130 ° C to 210 ° C, preferably 170 ° C to 210 ° C prevails in the melting zone of the extruder. It is particularly convenient to subdivide the zone of fusion in several segments that have different temperatures. According to the invention it is preferred to provide four segments in the melting zone, with a temperature of 177 ° C prevailing in the first segment, a temperature of 205 ° C prevailing in the second segment, a temperature of 50 ° C prevailing in the third segment. 188 ° C, and a temperature of 191 ° C prevails in the fourth segment. In another particularly preferred embodiment, a temperature of 120 ° C to 160 ° C, in particular 133 ° C, is set in the depression zone. The invention preferably provides for a pressure of 0.70 to 0.98 bar, in particular 0.78 bar, to be set in the depression area. According to a further development of the present invention, a temperature of 60 ° C to 130 ° C, preferably 120 ° C is set in the cooling zone. In particular, the invention provides for subdividing the cooling zone into several segments in the that there are different temperatures. According to the invention, three segments are preferred, in which a temperature of 120 ° C must be set in the first segment, a temperature of 120 ° C in the second segment, and a temperature of 80 ° C in the third segment. Indications on temperatures refer to the temperature in the extruder jacket and not in the casting. The melting temperature is approximately 20 to 30 ° C below the jacket temperature. The invention conveniently provides for making the extruder as a twin screw extruder. Naturally, the invention can be carried out with any extruders at will, as long as these can be configured according to the parameters according to the invention. In a particularly preferred embodiment, the invention provides for closing the extruder at its end and evacuating the mass extruded downwards. In accordance with this embodiment, a particularly clear casting with few bubbles results. Of course, it is also possible not to close the end of the extruder, but to provide an outlet nozzle there. The extruded mass then does not leave the extruder down, but in a straight line extension of the longitudinal axis of the screw. The invention also relates to a vitreous foundry which was produced according to a process according to the invention, a stampable rope which is suitable for the manufacture of solid candies or tablets, for example, and the products containing the casting. Conveniently during the subsequent processing prior to the casting of the casting, cooling of the casting on cooling bands is no longer required. The invention also relates to the use of a vitreous smelter according to the present invention for the manufacture of tablets, in particular by compression, or solid candies which preferably contain pharmaceutical active substances. Accordingly, the invention also relates to solids or tablets, preferably without sugar, containing the melting prepared by the process according to the invention and which can be produced from this melting by means of conventional processes. Other advantageous refinements of the invention are derived from the dependent claims. The invention will now be explained in more detail on the basis of the drawings and the corresponding embodiments. They show: FIG. 1 schematically the structure of an extruder applicable according to the invention, and FIG. 2 shows another embodiment of an extruder of this type, which has an inlet for dosing active substances and aromas. Figure 1 schematically illustrates the structure of a twin-screw extruder 100, (Togum, TO-EX 70) with a screw diameter of 70 mm and a length of approximately 4.0 m. The extruder is designed for a maximum capacity of 33 kW and works with a number of revolutions of 8 revolutions per minute. The extruder 100 has at one end an intake zone 110 which is configured as segment 1. The segment 1 has an opening 15 oriented upwards to introduce the mixture (arrow) of sweeteners. The fusion zone 120 follows the admission zone. The melting zone 120 is subdivided into four segments 2, 3, 4 and 5, where a Ti temperature of 177 ° C reigns in zone 2, a temperature T2 of 205 ° C prevails in zone 3, in zone 4 a temperature T3 of 188 ° C prevails, and in zone 5 a temperature T4 of 191 ° C reigns. Zones 2 to 5 are insulated and electrically heated.

Fusion zone 120 is followed by depression zone 130, which is designed in the form of segment 6 and has a T5 temperature of 133 ° C. Electric B heating is also provided here. Through it melts any material that splashes during the depression. In the zone of depression there reigns an air pressure P of 0.78 bar, which serves to degas the foundry. The depression zone 130 is followed by the cooling zone 140, whose design comprises three segments 7, 8 and 9. The segment 7 has a temperature T6 of 120 ° C, the segment 8 has a temperature T7 of 120 ° C, and the segment 9 has a temperature T8 of 80 ° C. The segment 9 has an outlet opening 20 facing downwards, through which the cooled iron (arrow) casting leaves. The temperature measurements are carried out on the extruder jacket. The temperature of the extrusion mass is approximately 20 to 30 ° C below the jacket temperature. For carrying out the present invention, for example, the twin screw extruders of the Togum company are commercially available under the TO-EX trademark and must be adjusted according to the indications of the present invention. The process according to the invention is carried out as follows: After the temperatures mentioned in the individual segments of the extruder 100 were adjusted by electric heating B and by cooling K by liquid carried out, for example, by what is known by "individual appliances", Isomalt R (an approximately equimolar mixture of 1.1-GPM and 1.6-GPS) is introduced into segment 1 through the inlet opening 15. The sweetener mixture is driven through the double rotating screws with a number of revolutions of 8 revolutions per minute, through the melting zone 120, the depression zone 130 and the cooling zone 140 with a flow volume of 50 kg of melt per hour, during which the mixture of Sweetener melts, degasses and cools. The casting is not made by separate coils or kneading elements. After the smelting is cooled to or below 100 ° C it is evacuated down out of segment 9. A clear casting with few bubbles with a temperature below or around 100 ° C is obtained. The smelter has a water content manifestly below 2% by weight and can be cooled to the temperature of a stampable cord, ie approximately 80 ° C, or can be directly stamped. For the production of solid candies, the stampable rope is first guided on a conical roller and then stamped to obtain solid candies by means of a common stamping press. For the production of tablets, the embossable rope is guided, for example, by means of rollers, as described, for example, in EP 0 240 906 Bl, thus producing the desired tablet form. Figure 2 depicts the structuring of another extruder that is substantially similar to the structure of the extruder of Figure 1, however it is provided in the cooling zone 140, particularly in the segment 8, an inlet opening 30 through which can be fed active substances of pharmaceutical activity, flavors, flavors, flavorings or dyes. By virtue of the lower melting temperature prevailing in zone 140, the spectrum of substances that can be incorporated in the melt is increased and its stability is increased.
