PURPOSE:To treat a large amount of an inner material having high water content and low viscosity mechanically, automatically and in a short time, by folding a specific continuous protein film into two and heat-sealing while rewinding the protein film to form a tubular material and carrying out heat sealing in the crosswise direction and feeding and packing of the inner material alternately and intermittently. CONSTITUTION:An edible protein solution or paste consisting of edible protein such as soybean protein, etc., fats and oils, a saccharide, a plasticizer, etc., and water is cast, heated, dried and wound to give a continuous protein film 6, which is folded into two in the stretching direction while rewinding, the opposing end parts are heat- sealed by heater rolls 1 at 120-135 deg.C in such a way that the film is stuck like folded palms or envelop to successively form a tubular material, which is optionally slit by a slitter 2 so that the sealing part width is made <=4mm. Then the tubular material is heat-sealed by a heater bar 3 crossing the stretching direction at 120-135 deg.C in such a way that the width of the sealing part is <=8mm and the prepared bag is packed with a material to be packed (inner material) through a piston pump 4 to intermittently feed the inner material. The heat sealing and the feeding and packing are alternately carried out and cutting is successively performed by a rotary cutter 5. |
