Pastillinvalmistus

The present invention relates to a process for preparing lozenges from a lozenge mass consisting of a selected consistency of a group consisting of gum arabic, starch, pectin, agar and mixtures thereof, optionally added with gelatin further comprising, if necessary, water other than sucrose, starch syrup, starch syrup, table salt, colorants, flavorings and / or other flavors.

Lozenges consist of a good-tasting base mass, which also contains various additives. The lozenges are intended to melt in the mouth and have a tough consistency, thus distinguishing from tablets which disintegrate upon contact with moisture and are therefore swallowed immediately. Pastilles have previously been made from crushed, warm-water-soluble gum arabic, filtered or purified dried gum arabic.

The water and acacia are then mixed with sucrose, starch syrup and possibly licorice, salt and / or salmia. Other sugars have also been used, such as fructose, glucose, sorbitol, xylitol, Lycazine (trade name, a mixture of different sugar alcohols marketed by Rochette Fre'res, Lille, France) and others. .This mixture is then heated to about 70 ° C to dissolve the sugar. This solution is brought to a dry matter content, usually about 63-67% by weight, so that it has a viscosity which is suitable for the casting equipment in the subsequent casting into lozenges.

To remove air from this mass, a so-called a jetcooker in which steam is injected into the pulp and the pulp is brought to a temperature of about 105 ° C. The heated mass is led to a vacuum chamber where air and steam are again removed. Optional additives such as colorants, flavors, and / or citric acid are added to the deaerated pulp to control taste and color. This mass is then used to cast the lozenges in a casting machine where the lozenges are cast with piston pumps, in molds rubbed with cornstarch. The cast lozenges 2 82881 are transferred in their molds to an oven, where they are dried at about 65 ° C in circulating air for about two days to a dry matter content of about 88% by weight. The lozenges are then allowed to cool for one day at room temperature, after which the corn flour with lozenges is turned up and down over a sieve so that the flour can be filtered out. The pastilles placed at room temperature are then brushed and possibly transported to a steam curtain where the remaining corn starch is glued. The water which then adheres to the lozenges is dried off, e.g. with IR lamps, after which the lozenges are cooled. To prevent tack and increase gloss, the lozenges are then surface treated in a drum with a mixture of paraffin oil and beeswax. The lozenges are then ready to be packaged.

In the case of starch-based lozenges, the gum arabic ingredient is replaced by starch. However, the starch must be glued in order to dissolve, which is why temperatures of up to 130-145 ° C must be used in jetcookers. Otherwise, lozenges are made in the same way as acacia-based lozenges. The main disadvantage of this known method is that it has to use molds with corn starch flour that dusts. In addition, cornmeal must be heated to a temperature of about 65 ° C, which is very energy intensive, as it requires about 4 kg of cornmeal / kg of ready-made lozenges. In addition, it takes about two days for the tablets to dry at a temperature of about 65 ° C to an acceptable dry matter content of about 88% by weight. As a result, large drying rooms are required, which in addition require high energy consumption for heating and air conditioning. In addition, the lozenges should be brushed, possibly moistened with a steam curtain, dried again and cooled, and the surface treated with paraffin oil and beeswax before they are ready to be packaged.

It is an object of the present invention to obviate these disadvantages and to provide good and uniform lozenges. The process according to the invention is mainly characterized in that the dry matter content of the lozenge mass is brought to more than 80% by weight, after which the taste and color are adjusted by adding colorants, flavors, citric acid and / or other flavors to the pulp, after which the whole mixture is mixed. in the absence of slime before the metered casting from the casting chamber to the molded plastic molds, the mass being in the casting chamber and into the molds during molding with water surrounded by moistened air to a water content in equilibrium with the vapor pressure of the lozenge mass.

It is noteworthy in the present invention that lozenges can be cast at a high dry matter content of more than 80% by weight, e.g. about 80-90% by weight, and that after casting the lozenges only need to be cooled before they are ready to be packaged. The method according to the invention therefore does not use molds containing corn flour, and as a result, the post-treatment of cast lozenges and energy-intensive treatment with corn flour are eliminated.

The process according to the present invention starts from a pastilles mass, the main ingredient of which is a consistency agent selected from the group consisting of Arabicomy, starch, pectin, agar and mixtures thereof, optionally added with gelatin. In addition to water, e.g. sucrose, starch syrup, sorbitol, xylitol, lycazine, fructose, glucose and / or other sugars are added to the consistency agent. If necessary, licorice or table salt can also be added. If desired, dye can also be added. This lozenge must be pumpable.

The lozenge is then pumped to a heat exchanger where it is preheated to the boiling point or, in the case of a starch-based lozenge, to the gluing temperature. After preheating, the lozenge mass is transported to an evaporator, where the dry matter content of the mass is increased to a value of more than 80% by weight. Only at this stage are any aro-30 flavorings, citric acid, other flavors and / or colorants introduced when the pulp is further pumped in the absence of air into the static mixer. After mixing in the mixer, the lozenge mass is conveyed in the absence of air to a casting chamber which is closed and has downwardly directed valves for casting. The temperature of the casting chamber must be above 35 at about 85-90 ° C, because the lozenge mass moves to an elastic state at lower temperatures. The higher the temperature, the faster the brown * 82881 color reaction occurs. The temperature of the casting canister should suitably be about 90-105 ° C. The chamber is further maintained at a pressure by means of air humidified with water vapor, whereby the water content of the air is in equilibrium with the vapor pressure of the lozenge mass. The casting takes place through valves 5 down into plastic molds which have been treated with a mold cream consisting, for example, of paraffin and beeswax. The casting itself is carried out under conditions such that the casting valves and molds are suitably surrounded by humidified air so that the water content of the air is again in equilibrium with the vapor pressure of the lozenge mass.

10

After casting, the molds are introduced into a cooling tunnel where the lozenges are cooled to room temperature. After cooling, the molds are turned up and down and the lozenges are pressed out onto a strip for further delivery to the package. The molds are reusable.

15

Compared to the previously known method, the lozenge mass is treated more carefully by the method of the present invention, in which case lower amounts of consistency, flavoring, coloring and / or other possible additives are required. In addition, the quality of the lozenges becomes more uniform, as it is difficult to achieve a uniform water content in the drying cabinet for all the lozenges in the cabinet. Energy savings are achieved as a result of eliminating the need for a dry matter content of 63-67% by weight in casting, as well as the need to heat large amounts of corn flour. In the process of the present invention, previously unavoidable post-treatments after casting can be omitted. It is clear from the appended claims what is characteristic of the present invention.

In order that the invention may be better understood, it will be described before the known method with reference to Figure 1 and with one embodiment of the method according to the invention with reference to Figure 2.

In Figure 1, a gum paste based on gum arabic is mixed in a mixer (A) where it is heated to a temperature of about 70 ° C so that the sugar 35 dissolves. The amount of water is adjusted so that its viscosity in subsequent casting is suitable for the casting equipment (dry matter content of about 63-67% by weight dry matter). From the mixer (A) the pulp is pumped for approx. jetcooker B in which steam is injected into the pulp to give a temperature of about 105 ° C. The heated lozenge mass is transported to a vacuum chamber (C) where air and added steam are removed from the mass. The deaerated mass S is then pumped into a mixer (D) in which a dye solution, flavorings and / or citric acid are added. After mixing these additives, the pulp is pumped into a casting machine (E), where pastilles are poured from the pulp by means of piston pumps into molds in which corn starch flour (F) has been placed. The molds are then transported to an oven 10 (G) where the lozenges are dried at 65 ° C in circulating air for about two days to a dry matter content of 88% by weight. The lozenges are then allowed to cool to room temperature for about one day. The molds are then turned up and down on a sieve (H) so that the cornmeal is sieved from the lozenges.

15

The lozenges are then brushed clean of the cornmeal and possibly transported to a steam curtain (I) where the remaining cornstarch is glued. The water that then adheres is dried off, e.g. with IR lamps, after which the lozenges are cooled, e.g. with cold air. Finally, a polishing step follows to counteract tack and increase gloss, with the lozenges being surface treated with a mixture of paraffin oil and beeswax in a drum (K). The lozenges prepared from the drum are transported to the package (L). When preparing starch-based lozenges instead of gum arabic, the procedure is the same, except that a temperature of 130-145 ° C must be reached in the jetcoo-25 coil to glue the starch.

Figure 2 is a schematic flow chart of the method of the present invention. The pastille mass based on gum arabic is mixed in a mixer (1), whereby its dry matter content is adjusted so that the mass becomes pumpable. The lozenge mass is then pumped inside a preheater (2), where the mass is heated to its boiling point or, in the case of a starch-based mass, to the starch bonding temperature. After preheating, the pulp is transported to an evaporator (3), where the pulp is evaporated to a dry matter content of e.g. 85-95% by weight-35%. The pulp is then further pumped through a pipe to which a tank (4) is also connected to add flavorings, colorant solutions, citric acid, other flavors and / or colorants. The tubes settle into a static mixer 5 where the additives are mixed into the pulp before it enters the casting chamber 6. This chamber is closed by downwardly directed valves for casting. The temperature in this chamber is suitably maintained in the range of 90-105 ° C. The chamber is still kept under pressure by means of air moistened with steam, whereby the water content of the air is in equilibrium with the vapor pressure of the lozenge mass. The mass is then cast through valves down into plastic molds pre-coated with mold cream (7). During the casting, the valves and molds of the casting chamber (6) are in a state where the air is humidified with steam under the same conditions as in the casting chamber. After casting, the notes are transported to a cooling tunnel (9) where the lozenges are cooled to room temperature. After cooling, the molds are turned up and down (10) and the lozenges are pressed onto the strip (11) to deliver them to the package 15 (12). The molds are returned (13) to the casting stage.

The invention will now be illustrated by a few exemplary embodiments.

Example 1 20

The pastilles mass was made from the following ingredients: 36.2 kg crushed gum arabic 25.9 kg sucrose 25 12.5 kg starch syrup (glycos 40 (Reppe Glykos, Växjö, Sweden)) 1.1 kg trisodium citrate 0.005 kg dye (erythrosine) 24.3 kg water 30 The above ingredients were mixed together and diluted with water to a dry matter content of 67% by weight. The temperature of the mixture was 38 ° C. It was pumped into a preheater, Contherm 6x3 from Alfa-Laval Lund, Sweden, using a mono pump H32 from Alfa-Laval. The preheater was a scraper heat exchanger with a rotor speed of 300 rpm and water vapor at 140 ° C was used as the heat exchanger. The mixture was heated to 122 ° C and the inlet flow was 118.5 kg / h. The warm pulp was transported to 7,82881 evaporators, Convap type 6x3 from Alfa-Laval, Lund, Sweden. The rotor speed in the evaporator was 900 rpm and the steam temperature was 169 ° C. The vacuum in the evaporator was adjusted with a vacuum pump so that the boiling temperature became 98 ° C. At lower boiling temperatures, viscosity-5 becomes too high and at higher boiling temperatures, the inversion of sugar increases, resulting in a sticky product. The outflow from the evaporator was 90 kg / w / h and the dry matter content was 88% by weight. The pulp was now further pumped by Nemopump, Alfa-Laval. The citric acid solution (dry matter content 60% by weight) and flavoring 10 were pumped into the dosing pump pulp in appropriate amounts to control the taste and all were allowed to pass through a static mixer (Static mixer (USP 328 6992) from Kennics Corporation, Downings, Mass. USA) before the pulp arrived. temperature 98 ° C, overpressure 0.8 bar, humidity approx. 60%.

Example 2

The pastille mass was made from the following ingredients.

20 28.6 kg of starch type (Perfectamyl gel 45 Stadex, Malmö,

Sweden) 26.8 kg sucrose 20.2 kg starch syrup (14.7 kg glucose 40 and 5.5 kg glucose 60 from Reppe Glykos, Växjö, Sweden) 25 1.6 kg sorbitol (Neosorb 70/70. Roquette Frö res, Lille Cedex,

France) 0.02 kg dye (beta - carotene) 52 kg water 30 The same process equipment was used as in Example 1.

The ingredients were mixed with water to a dry matter content of 69% by weight. The starch was unglued. The mixture was pumped at a flow rate of 123 kg / h into a preheater where the temperature was raised from 48 ° C to 35 ° C with steam. To prevent boiling, a back pressure valve was installed in the preheater before the evaporator. The function of the preheater in this case was not only to preheat the pulp but also to glue the starch. The pulp was evaporated to a dry matter content of 88% by weight with water vapor at 168 ° C as a thermal medium. The pulp was further pumped by means of a monopump H32 from the evaporator with an outflow of about 96 kg / h 5 and a temperature of 98eC. The lozenge was then treated in the same manner as in Example 1.
