- the invention relates to an improved method for the preparation of conditioned powder from coarse-grained or crystalline substances, in particular for the preparation of conditioned powdered sugar.
- Powdered sugar is a by crushing crystalline Sugar-made product, the Grain size is generally less than 0.1 mm.
- the large surface of the ground sugar is affected in connection with the good water solubility of the Sucrose the shelf life of powdered sugar strong. So shows in a dry atmosphere ground Icing sugar through the grinding process and that connecting melting of the sugar on the fracture surface and the rapid cooling in the airflow glassy Structures on its surface. In the Inclusion of adsorption isotherms shows that this powdered sugar to adsorb high amounts of water can. By absorbing the water a recrystallization process on the surface of the Powdered sugar grains initiated. The recorded Water is quickly released again.
- the basis of the present invention So the technical problem is a process for the preparation of conditioned powder from coarse-grained or crystalline substances, in particular from granulated sugar, which is available in as short a time as possible and without major construction Effort to generate well storable, that is conditioned powder allows.
- the technical problem underlying the invention is solved by a manufacturing process of conditioned powder, especially conditioned powder Powdered sugar is provided, whereby the coarse-grained or fine-crystalline used Substances, especially the one used Sugar, ground and conditioned and being the conditioning of the substances during grinding he follows.
- the invention therefore provides that the Conditioning, that is, the treatment of Fabrics in such a way that during the Storage no longer become hard, not in a separate, conditioning step following the grinding process is performed, but at the same time with the grinding.
- the invention accordingly the advantage that conditioned substances, especially conditioned sugar, already after the grinding, so that a time-consuming Post-treatment is no longer necessary.
- the invention relates in a particularly preferred manner Way of making conditioned powdered sugar from sugar, for example galactose or preferably sucrose, for example as Refined sugar (EG quality I) or granulated sugar (EG quality II) can be present.
- sugar for example galactose or preferably sucrose
- EG quality I Refined sugar
- EG quality II granulated sugar
- the invention can also be used for substances of others Composition, but the same or similar physical Properties to be used. such, a coarse-grained or crystalline structure containing substances can also be pectins.
- According to the invention can also mix different substances Composition in a single step ground together and conditioned become.
- the invention relates to the aforementioned method, which is used at elevated Water content, especially with increased water content the air, particularly preferred with an absolute Air humidity (in g water per kg drier Air) of at least 17 g / kg, preferably of 17 g / kg to 30 g / kg and particularly preferably 25 to 26 g / kg.
- the one during grinding Conditioning is therefore preferred Execution solely by the fact that the humidity in the grinding chamber is increased.
- the Use of grinding aids such as organic Solvents, is not necessary, but will excluded according to the invention in a preferred embodiment.
- the invention also relates to an aforementioned method, taking the conditioning at temperatures from at least 25 ° C, preferably from 25 ° C to 70 ° C, particularly preferably at 40 ° C to 48 ° C, in particular 45 ° C, is carried out.
- the invention is expressly not limited to the minimum values for air humidity and temperature mentioned.
- Critical to the invention success is particularly the simultaneity of grinding and conditioning, wherein the discontinuing the conditioning parameters in a simple and known manner can be determined by the conditioning means of determination of a W -value (water activity), the lump number or invert sugar moiety is assessed and the parameters are adjusted accordingly.
- the temperature is preferred and the humidity during conditioning and grinding constantly, for example by means of electronic control devices.
- the invention also relates to the aforementioned Procedure, following the simultaneously grinding and conditioning an intermediate storage is connected, the Duration essentially depends on the process engineering Parameters of the environment is determined.
- the conditioning provided according to the invention downstream optional intermediate storage can be done by a simple stirred tank as a buffer container between Mill and packaging system is installed, the one defined interim storage time of the powdered sugar guaranteed.
- This buffer container enables one constant movement of the powdered sugar.
- Example 1 Preparation of conditioned icing sugar from sucrose.
- FIG 1 shows schematically the structure of an invention grinding room system 100 to be used This includes a grinding room 1, a discharge shaft 2, a rotary valve 3 and a screw conveyor 5.
- the grinding chamber 1 has a mill 7 with a sugar feed shaft 9 and a suction opening 8 on.
- the grinding chamber 1 also has a filter 11 and a fan 13.
- Figure 1 also represents a heater 23.
- the function of the system 100 is as follows represents.
- a temperature of 40 ° C. with a fluctuation range of ⁇ 1 ° C. is constantly set in the grinding chamber 1.
- the humidification system 19 is designed so that a water loading of the grinding chamber air of 18 g water per kg dry air is possible.
- crystalline sugar Z is introduced into the mill 7 via the feed shaft 9 and ground.
- the grinding process therefore takes place in a tempered and humidified grinding chamber 1 (volume of the grinding chamber 1: 193 m 2 ).
- the air intake of the mill 7 through the intake opening 8 is 2,300 m 3 / h.
- the purge air quantity SL is used to clean the filter 11.
- the throughput of the fan 13, which is connected downstream of the filter 11, is 2,520 m 3 / h.
- the fan 13 removes both the purge air SL and the intake air AL of the mill 7.
- the intake air AL for the mill 7 comes directly from the grinding chamber 1, while the purge air SL is dry control air which enters the grinding chamber 1 from the outside.
- the system 100 shown in FIG. 1 was used about different settings of the moisture loading the grinding chamber air of 12 to 26 g / kg dry Examine air, taking the grinding chamber temperature was at 40 ° C.
- the through the heater 23 achieved temperature must be by means of a in this Integrated control device constant being held.
- FIG. 2 shows the course over time of the a W value of powdered sugar samples (sucrose), measured at 40 ° C., the samples being ground at different moisture loads in the grinding chamber air.
- the a W value (water activity) defines the relative humidity that must prevail in the atmosphere surrounding a sample in order to avoid any water exchange between the sample and the air. It is given in units of 0 to 1 and therefore indicates the relative humidity that arises in a closed room above a substance sample at a defined temperature.
- FIG. 2 shows samples of the freshly ground powdered sugar, each with different settings the grinding chamber humidification were generated.
- Freshly ground Powdered sugar with a moisture load on it Grinding chamber air of over 17 g / kg dry air is generated has therefore been conditioned. A subsequent subsequent to the grinding Conditioning is therefore unnecessary.
- the invention powdered sugar even after a long time Time is of excellent quality. This can be demonstrated quantitatively, for example be by using a mesh size of 0.300 mm is sieved and no residue remains.
- Conditioned sugar also shows after years Storage under defined conditions no lump formation on.
- Example 2 Conditioning icing sugar with subsequent interim storage
- FIG. 1 shows the system 100 according to FIG. 1 in such a way that between the mill 7 and the packaging system (not shown), for example following the screw 5, a stirred tank, which is designed as a circulation tank, is used, which serves as a buffer or intermediate tank , FIG. 3 shows the course over time of the a W value of ground powdered sugar during such an intermediate storage depending on the duration of the intermediate storage (measured at 40 ° C.).
- the moisture loading of the grinding chamber air was 25 to 26 g / kg dry air (at 40 ° C temperature in the grinding chamber), while the moisture loading of the conditioning air exchanged during the intermediate storage in the head space of the stirred tank (circulation) was 11 to 12 g / kg drier Air was fraud.
- the powdered sugar samples are to be classified as conditioned from the beginning to the end of the intermediate storage according to the time course of the a W values.
- FIG. 4 shows the time course of the a W value of powdered sugar during the conditioning as a function of the duration of the intermediate storage (measured at 40 ° C.).
- the moisture content in the grinding chamber air was 17 g / kg dry air (40 ° C. ), while the intermediate storage took place without the supply of tempered or humidified air.
- the buffer tank used for the intermediate storage there is therefore only circulation, but no conditioning by adding tempered or humidified air.
- the powdered sugar samples are to be classified as conditioned from the beginning to the end of the intermediate storage according to the time course of the a W values.
