DST dehumidifiers at Jämtgott AB enable consistent drying of candy in order to guarantee confectionery of the best quality, and concurrently ensure energy efficient production.
Just outside Östersund in Sweden, you find Jämtgott, a candy factory that started manufacturing confections in 1968. The production is still done in the same way as it was when the factory started, however everything has been streamlined to be able to produce more whilst being energy efficient especially during drying of the candy. After the candy is mixed, it is poured into moulds, where it is dried. The molds are then placed in a warm drying room in order to evaporate moisture from the candy. This requires a controlled climate in order to achieve the best quality.
In the past, the confectionery was dried by placing it in a warm room with ventilation that exuded the moisture. It worked very well but it was quite difficult to dry the candy evenly.
When Jämtgott increased their sales, they also needed to be able to increase control over the drying process of the candy. Their consultant came to DST’s representative Polair Luftteknik AB for help. The solution offered was a DST dehumidifier that would supply dry air, through ducts installed at floor-level of the drying room. In this way, the dry air would spread upwards through the moulds, and then out via ventilation ducts in the ceilings. This vented air would then be re-circulated to the dehumidifier unit. With this new system, the candy is dried more evenly than before.
The DST dehumidifier installed at Jämtgott has a PLC which makes it easy to communicate with the unit without being physically present. It also allows the unit to be programmed according to different drying cycles depending on the product being produced. As such, Jämtgott AB have total control over the drying conditions for their candy, which enables them sell products of the highest quality.
