The steaming tunnel is a versatile and reliable device for exposing the tobacco to a treatment with steam. The capacity range of the steaming tunnel from HEINEN KÖHL can vary up to 10.000 kg/h and for low capacity production the steaming zones can be switched off.
For the process three options are available: Expansion of cut lamina and cut stems, conditioning of stems and steaming of strips and stems.
The steaming tunnel of HEINEN KÖHL mainly consists of:
- steel base frame
