Expanded tobacco batching and cold end processing

  Cut lamina is weighed by the batch and fed into one of two saturation vessels, called impregnators. Once the impregnator is sealed, liquid carbon dioxide floods into the vessel at a high pressure. After a soaking period, the impregnator is opened and the frozen tobacco is discharged at -78°C.
