One of the characteristics of tobacco is that it absorbs a lot of moisture in high ambient temperatures and exudes it again as condensation at lower temperatures. This leads to a large population of micro-organisms that cause discoloring, mold, insects and other phenomena. The result: a serious deterioration in quality and considerable economic losses.
Permanent monitoring of the climatic conditions is therefore an extremely important factor in the manufacturing process of quality cigarettes and cigars.
It is important that humidity and temperature are also measured during the drying process in which the optimum equilibrium relative humidity of the tobacco is attained.
The equilibrium relative humidity of cigars is determined by measurement of the water activity. Rotronic water activity probes work with digital HygroClip technology, which ensures their high performance and simple digital adjustment and calibration. Handheld instruments with insertion probes are used to measure bales of tobacco leaves, while water activity units tend to be used in the laboratory environment.
Last but not least, climate data such as relative air humidity and temperature are also recorded during transport and storage. Only in this way is it possible to document that tobacco products were transported or stored under perfect conditions and without loss of quality. This can be a key factor for acceptance of a delivery.
