This hot air is returned to the sterile air compressor and, in conjunction with this, any residual hydrogen peroxide in the air is removed by washing with water which is collected in a special sepa nding roller 12. The product to be packed is introduced through the stainless steel filling tube, which is jacketed by a second tube through which sterile hot air can be blown into the paper tube.
