Biscuits are popular snacks made by mixing flour, sugar, and fat in various proportions and baking them. The dough obtained at the beginning of the process is shaped into biscuits and baked in the oven. The hygroscopic properties (moisture absorption) of the ingredients used in the production of these delicious products should be considered. Freshly baked, hot biscuits are still too warm for packaging and need to be cooled to room temperature before packaging. The use of cooling tunnels with different designs, integrated with industrial dehumidifiers, is crucial for preserving product quality and extending shelf life. If biscuits are exposed to high relative humidity while being rapidly cooled to room temperature after baking, they may soften, leading to quality deterioration before packaging. Additionally, if the surface temperature of the biscuits is below the dew point temperature of the packaging area at the exit of the cooling tunnel, partial condensation can occur on the biscuit surfaces. Moisture absorption by the biscuits can cause them to soften, reducing their appeal and shortening their shelf life.
As the biscuits are exposed to various levels of cold air throughout the cooling tunnel, the dehumidifier controls the humidity levels inside. The relative humidity level in cooling tunnels integrated with dehumidifiers should be set to prevent condensation. The temperature and humidity of the packaging area should also be controlled at the exit of the biscuit cooling tunnels with integrated dehumidifiers. After cooling, the biscuits are placed in airtight packages to preserve their quality and extend their shelf life. If the relative humidity level in the packaging room is high, the biscuits can reabsorb moisture while waiting to be packaged. The humid air can also be sealed inside the packages with the biscuits. Temperature differences between the packaging location and the destination can cause condensation and sweating inside the package. Therefore, controlling the humidity of the packaging area and actively using dehumidifiers directly affect the quality and shelf life of biscuits.
The use of industrial dehumidifiers in biscuit production plays a vital role in product quality, shelf life, and consumer satisfaction. It not only improves quality and efficiency for biscuit manufacturers but also contributes to long-term sustainability goals by saving energy. Therefore, investing in industrial dehumidifiers is a critical step that directly affects product quality and market success for biscuit manufacturers.
