ABSTRACT:
To remove air from pouches filled with foodstuffs or other products prior to sealing, equipment has been used which opens the top of the pouch, inserts a nozzle, injects steam through the nozzle, draws the edges of the top of the pouch together and then seals the top edges. The present invention is an improvement in the nozzle construction which prevents droplets of water from condensing on the top edges of the pouch, a deficiency of the prior art which inhibits an air-tight seal. The nozzle has an inner tube with a flared terminus which is lowered into the pouch, the tube being surrounded by a jacket connected to a source of saturated steam at about 50-60 psi. An adjustable pressure reducing orifice interconnects the jacket and tube so that the steam pressure emitted from the terminus is reduced to near atmospheric pressure and the temperature is increased to about (270.degree.-290.degree. F.)
