  The present invention can execute efficiently the provision of a film-formable thermoplastic composition containing polysaccharides and proteins as the main ingredients or the preparation of polyester foamed products of practical utility by compressing a substance together with carbon dioxide and processing it as a fluid of critical state. An equipment useful for it is a screw type processing equipment for compressing a substance together with carbon dioxide continuously to give a fluid of critical state and the equipment is one in which the extruding screw having next to the raw material supplying part X, a vacuum part E in which the shaft of said screw is made thin and the gap volume between the screw blades is increased is provided and carbon dioxide is introduced to the vacuum part E and furthermore after the vacuum part E a compressing part F in which the shaft is again thickened and consisted of a screw having narrowed blade intervals is placed and then the thickness of the shaft is made to be substantially same as the periphery of the barrel and an orifice part L is provided in which an orifice 17 is provided on the surface or on the surroundings of said shaft. The maximum flow rate of the substance passing through the orifice is preferably designed to be 10 to 1500 cm/second.

  A screw type processing device provides a film-formable thermoplastic composition formed mainly of polysaccharide and protein by continuously compressing substances together with carbon dioxide gas to form fluid in a critical state, processes the fluid and is capable of efficiently manufacturing a practicable polyester foam body. A pressure reduction part with increased space volume between screw vanes is formed continuously with an extruding screw of a material supply part by reducing the diameter of the shaft of the screw, and carbon dioxide gas is led into the pressure reduction part. Also, a compression part formed of a screw having a shaft with increased diameter and narrowed vanes is positioned after the pressure reduction part. The diameter of the shaft is made substantially equal to the inner periphery of a barrel, and an orifice part having an orifice formed on the surface or periphery of the shaft is formed. The maximum flow velocity of orifice passing substances is desirably designed to be 10 to 1500 cm/sec.
