Description

The water that then sticks to the lozenges is wiped off with, for example, IR lamps, after which the lozenges are cooled. To then counteract sticking and increase the gloss, the pastilles are surface-treated in a drum with a mixture of paraffin oil and beeswax.

The lozenges are then ready for packing.

When making lozenges based on starch, the gum arabic ingredient is replaced with starch. However, the starch must be pre-glued in order to be dissolved, which is why the jet cooker must go up to 130-145 ° C. In other respects, the lozenges are produced in the same way as the lozenges based on gum arabic.

The main disadvantage of this known method is that one has to use molds with corn starch flour, which dust. In addition, the cornmeal must be heated to about 65 ° C, which is very energy-intensive due to the fact that about 4 kg of cornmeal is required per kg of finished lozenges.

In addition, it takes about 2 days for the tablets to dry at about 65 ° C to an acceptable dry matter content of about 88% by weight. This means that large drying rooms must be provided, which also require a large energy supply for heating and ventilation. Furthermore, the lozenges must be brushed, possibly moistened with a steam curtain, dried and cooled again and surface treated with paraffin oil and beeswax before they are ready for packing. The object of the present invention is to obviate these disadvantages and to provide lozenges of good and even quality.

The characteristic of the present invention is that the lozenges can be cast at a high dry matter content of over 80% by weight, for example about 85-90% by weight, and that the lozenges after casting only need to be cooled before they are ready for packing. Consequently, in the process according to the invention, molds with maize flour are not used and thus post-treatment of cast pastels and energy-intensive handling with maize flour is eliminated.

The process according to the present invention is based on a lozenge mass, the main constituent of which is a consistency sensor selected from the group consisting of gum arabic, starch, pectin, agar and mixtures thereof, optionally with the addition of gelatin. In addition to water, for example, sucrose, starch syrup, sorbitol, xylitol, lycasin, fructose, glucose and / or other sugars are added to the conditioner. If necessary, licorice and table salt can also be added. If desired, a dye can also be added. This lozenge must be pumpable.

The lozenge is then pumped to a heat exchanger where preheating takes place to the boiling point or in the case of starch-based lozenge to a pre-paste temperature. After the preheating, the lozenge mass is transported to an evaporator where the dry matter content of the pulp is increased to over 80% by weight. Only at this stage are any flavorings, citric acid, other flavors and / or colors introduced when the pulp is pumped further in the absence of air to a static mixer. After mixing in the mixer, the lozenge mass is transported in the absence of air into a casting chamber, which is closed and which has downward-pointing valves for casting. The temperature in the casting chamber must be above about 85-90 ° C due to the fact that the pellet mass at a lower temperature changes to an elastic state. The higher the temperature, the faster the browning reaction takes place. The temperature in the casting chamber should suitably be about 90-105 ° C. The chamber is further kept under pressure by means of air which is moistened with water vapor, the water content of the air being in equilibrium with the vapor pressure of the lozenge mass. Casting takes place through the valves into plastic molds that are treated with release agents consisting of, for example, paraffin and beeswax. The casting itself is carried out under such conditions that the casting valves and molds are enclosed by suitably moistened air so that the water content of the air is again in equilibrium with the vapor pressure of the pastel mass.

After casting, the molds are transported into a POOR QUALITY 8402472-8 10 15 20 25 30 35 4 cooling tunnel, where the lozenges are cooled to room temperature.

After cooling, the molds are turned upside down and the lozenges are pressed out on a belt for transfer to packing. The molds are reusable.

Compared with the previously known method, the lozenge mass is treated more gently by the method according to the invention, whereby smaller amounts of consistency sensors, flavorings, dyes and / or other possible additives need to be used. In addition, the quality of the lozenges becomes more even, because in drying cabinets it is difficult to achieve an even water content for all lozenges in the cabinet. Energy savings are achieved as a result of the need for a dry matter content of 63-67% by weight during casting, as well as the need to heat large amounts of maize flour. In the process of the present invention, the previously necessary post-casting finishes can be completely omitted. The features of the present invention are set forth in the appended claims.

To better understand the invention, the prior art method will now be described with reference to Fig. 1 and an embodiment of the method according to the invention with reference to Fig. 2.

In Fig. 1, a lozenge based on gum arabic is mixed in a mixer (A), where it is heated to about 70 ° C so that the sugar dissolves. The amount of water is adjusted so that during the latter casting it has a viscosity that suits the casting equipment (approx. 63-67% by weight dry matter content). From the mixer (A) the pulp is pumped to a so-called jet cooker (B) in which steam is injected into the pulp so that a temperature of about 105 ° C is obtained. The heated pastili mass is transported to a vacuum chamber (C) where the air and the added steam are removed from the mass. The aerated mass is then pumped to a mixer (D) where a dye solution, flavorings and / or citric acid are added. After mixing these additives, the pulp is pumped to a casting machine (E) where lozenges are cast from the pulp by means of piston pumps in molds molded in corn starch flour (F). The molds are then transported to a heating cabinet (G), where the lozenges are dried at about 65 ° C in circulating air for about 2 days to a dry matter content of about 88% by weight. The lozenges are then allowed to cool for 1 day to room temperature. The molds were then turned upside down over a sieve (H) so that the cornmeal was sieved from the pastilles.

The lozenges are then brushed clean of cornmeal and possibly transported to a steam curtain (I) where the remaining corn starch is glued. The water that then gets stuck is wiped off with, for example, IR lamps (J), after which the lozenges are cooled, for example, with cold air. drum (K). From the drum, the finished lozenges are transported to packing (L).

In the manufacture of lozenges based on starch instead of gum arabic, the procedure is the same, except that in the jet cooker you have to go up to i3o-14s ° c to chalk the starch ice.

Fig. 2 shows a schematic flow diagram of a method according to the present invention. A paste-based pulp based on gum arabic is mixed in a mixer (1), whereby its dry matter content is adjusted so that the pulp becomes pumpable. The lozenge mass is then pumped into a preheater (2), where the mass is heated to its boiling point or in the case of starch-based mass to the pre-sticking temperature of the starch. After preheating, the pulp is transported to an evaporator (3), where the pulp is evaporated to, for example, a dry matter content of about 85-90% by weight. The pulp is then pumped further through a pipe to which a container (4) is also connected for the supply of flavorings, dye solutions, citric acid, other flavors and / or dyes. The tube opens into a static mixer (5) where the additives are mixed into the mass before it enters a casting chamber POOR QUALITY 10 15 20 25 30 35 8402472-8 6 (6). This chamber is closed with downwardly directed valves for casting. The temperature in this chamber is suitably maintained at 90-105 ° C. The chamber is further maintained under pressure by means of air moistened with steam, the water content of the air being in equilibrium with the vapor pressure of the lozenge mass.

The mass is then cast through the valves into plastic molds which have been pre-coated with release agent (7). The valves of the casting chamber (6) and the molds are located during the casting in a space where the air is moistened with steam under the same conditions as in the casting chamber. After casting, the molds are transported into a cooling tunnel (9) where the lozenges are cooled to room temperature. After cooling, the molds are turned upside down (10) and the lozenges are pressed out on a belt (II) for transfer to packing (12).

The molds are returned (l3) to the casting step.

The invention will now be illustrated by some embodiments. ~ Bxemgel 1 'A pastel mass uçpgjoríes of íëljnni fl Ingredients: 36.2 kg crushed gum arabic 25.9 kg sucrose 12.5 kg starch syrup [glucose 40 (Reppe Glykos, Växjö, Sweden)] 1.1 kg trisodium citrate 0.005 kg dye (erythrosine) 24.3 kg of water The above ingredients were mixed and diluted with the water to a dry matter content of 67% by weight.

The temperature of the mixture was 36 ° C. It was pumped into a preheater, Contherm 6 x 3 from Alfa-Laval, Lund, Sweden, using a mcno pump H32 from Alfa-Laval.

The preheater was a scraper heat exchanger with a rotor speed of 300 rpm and water heat via 134% was used as the heating medium. The mixture was heated to 1z2 ° C and the infusion was 18.5 kg / h. The hot mass was transported into an evaporator, Convap type 6 x 3 from Alfa-Laval, Lund, Sweden. The rotor speed of the evaporator was 900 rpm and the steam temperature was 169 ° C. The negative pressure in the evaporator was controlled with a vacuum pump so that the boiling temperature became 98 ° C. At lower boiling temperatures the viscosity becomes too high and at higher boiling temperatures the inverting of sugar increases, making the product sticky. The outflow from the evaporator was 90 kg pulp / h with a dry matter content of 88% by weight. The mass was now pumped on with a Nemo pump, Alfa-Laval. Citric acid solution (dry matter content 60% by weight) and flavoring were pumped in appropriate quantities by means of dosing pumps into the pulp to adjust the taste and the whole was passed through a static mixer [Static Mixer (USP 328 6992) Kennics Corporation, Downings, Mass., USA] before the pulp arrived into the casting chamber (temperature 98 ° C, overpressure 0.8 bar, humidity approx. 60%).

Example 2 A lozenge mass was made up of the following ingredients: 28.6 kg of starch (type Perfectamyl gel 45 from Stadex, Malmö, Sweden) 26.8 kg of sucrose 20.2 kg of starch syrup (14.7 kg of glucose 40 and 5.5 kg glucose 60 from Reppe Glykos, Växjö, Sweden) 1.6 kg sorbitol (Neosorb 70/70, Roquette Frêres, Lille Cedex, France) 0.02 kg dye (beta-carotene) 22 kg water The same process equipment was used as in example l.

The ingredients were mixed together with the water to a dry matter content of 69% by weight. The starch was unstuck. The mixture was pumped at an inflow of 123 kg / h to the preheater, where the temperature was increased from 4a ° c to 1zs ° c by means of steam via 137%.

To prevent boiling in the preheater, a back pressure valve was fitted before the evaporator. The task of the preheater in this case was not only to preheat the mass but also to pre-paste the starch. The mass was evaporated to a dry matter content of 88% by weight by means of water vapor at 16,400 as heating medium. The mass was further pumped by means of a monopump H32 at an outflow from the evaporator of about 96 kg / h and a temperature of 98 ° C. Thereafter, the lozenge mass was treated in the same manner as in Example 1.
