ABSTRACT:
Containers (such as metal, glass, plastic, fiber, but not limited thereto) are sterilized in a section of the apparatus having a helical or spiral belt conveyor within an insulated casing through which air above atmospheric pressure at up to about 500.degree. F. is circulated by means of a heater and blower, in a recirculation path. The containers then travel along a straightline encased conveyor where sterile air above atmospheric pressure prevents ingress of non-sterile ambient air. During part of the path through the straight-line conveyor, the containers are driven by a helical screw which forces the containers into close proximity (in fact the out-turned flanges of the containers preferably overlap). Pre-sterilized, preferably cooled, product is delivered into the containers preferably through a curtain, slit-type filler. Other fillers, such as rotary fillers, may be used. The speed of the containers is timed to deliver the desired product volume into the containers. Thereafter, filled containers are accepted by a container closing machine. Container lids or covers (herein "lids") are sterilized in a section of the apparatus where lids are moved along a conveyor and sterile air which has been heated is forced by a blower into the lid sterilizer section. The lids then travel up a tunnel at greater than atmospheric pressure, where they are cooled and delivered to the closing machine. The closing machine applies the sterile lids to the containers at greater than atmospheric pressure.
