The Expansion Tunnel is designed to expand cut tobacco or stems by passing steam through it. The machine uses a free jet system to transfer the thermal and mechanical energy of the steam to the tobacco product. During the flow through the Expansion Tunnel the tobacco carpet passes through several rows of nozzles injecting steam at predetermined speed. The tunnel provides optimal exposure of the tobacco to the drying process, boosting tobacco expansion and thereby increasing the filling power in the cigarettes.The robust construction and reliable performance of the Expansion Tunnel ensure optimal productivity.
