摘要:
The injection device (3) according to the invention, intended to be attached to the wall of the bottom of a container containing a product to be cooled in bulk, comprises a hollow cylindrical body in which a valve (17) forced by a spring (19) is inserted, a through-channel (18) appreciably parallel to said valve intended to be fed by pressurized cryogenic fluid, one end of said through-channel being connected to the cryogenic fluid feed system and the opposite end opening into the seat (13) of the valve.
摘要:
The present invention relates to a method and device for packaging dry ice in a plastic film, the said device comprising: - means for dispensing and shaping a plastic film comprising a shaping sleeve (20) over the exterior wall of which the plastic film (22) is paid out, - a dry ice generator (16) connected to a source (3) of liquid carbon dioxide, the dry ice generator (16) being positioned inside the shaping sleeve (20) so as to leave a gap between the generator (16) and the shaping sleeve (20) and allow the plastic film (22) shaped to become filled with dry ice, - and means (23, 28) for sealing the shaped plastic film, characterized in that the shaping sleeve is equipped with thermal insulating means and/or with heating means (28, 30, 31).
