Tatlı arzusu insanoğlunun en temel güdülerinden biri olup şeker bize enerji sağlayan önemli bir besin kaynağımızdır. Hızlı temin edilebilen bir karbonhidrat olarak fiziksel egzersizler ve spor aktiviteleri esnasındaki performansımızı artırmamıza yardımcı olur. Şeker Orta Avrupa'da yetişen şeker pancarından elde edildiği gibi, tropikal bir bitki olan şeker kamışından da elde edilir. Sakaroz, doğrudan bu kültür meyvelerinde mevcut olan bir madde olup bunlardan sulu çözeltiler haline kaynatılıp kristalleşme meydana gelene kadar kaynatma işlemine devam edilerek elde edilir. İstenen arılık derecesine göre şeker tekrar tekrar arıtılır ve kristalize edilir. Günlük kullanımdan bildiğimiz "kaba" şeker kristallerinden başka, birçok özel ve endüstriyel kullanım alanında daha ince şeker türleri gerekir, örn. pudra şekeri. Bu ince şeker tozu şeker kristallerinin modern darbeli değirmenlerle mekanik öğütme yöntemiyle gerçekleşir.
In the past, only conventional pin mills were used. Today, considerably higher throughputs can be obtained using so-called blast mills. The usual powdered sugar finenesses of 80 – 95% < 100 µm can be obtained, as well as considerably higher finenesses.
Perhaps the higher product qualities achieved are even more important than the high throughput capacities and product finenesses. These qualities are valued due to the low invert sugar content of the product which is obtained due to the principally lower grinding temperature within the powder mill.
The plant technology regarding dust explosions and the realization of modern safety concepts are also crucial points for the grinding of powdered sugar. The grinding of crystal sugar makes high demands on the technology to be used, as well as on the execution of a grinding plant, as the danger of dust explosions cannot be excluded during the mechanical grinding of sugar. Adequate constructional explosion measures, which can be realized as part of various plant designs, are necessary for this:
- The shock pressure resistant design up to an excess explosion pressure of 10 bar(g) of the complete grinding system in a conventional assembly, has been the most frequently used version up until now.
- A pressure-relieved plant, designed for a reduced explosion pressure of 3 bar(g), in which the so-called pressure relief is carried out via a rupture disc integrated in a dust filter to a non-endangered exterior area.
- The new ATEX-compliant plant design Condux® Compact has now made the installation of a high-performance sugar-grinding plant considerably easier: Explosion protection valves or explosion-suppression equipment, explosion-decoupling, ventilators and even dust filter systems are no longer necessary in the classical sense.
