Heinz Frozen & Chilled Foods in Okehampton, Devon has installed a high-speed twin-lane Tecnovac Cronos traysealer supplied by Planet Flowline for packing frozen desserts in 95mm diameter round trays.
Trays are fed randomly from a spiral freezer in a single lane, and are then split into two lanes by a diverter belt before entering the sealing machine. The trays are spaced on an infeed belt and, when 12 are collated, arms automatically transport them to the tool, where they are sealed and the film is profile cut. When a further 12 trays are in position, they are transferred to the tool at the same time as the sealed trays are removed onto the discharge conveyor.
The Cronos machine supplied to Heinz Frozen & Chilled Foods is for atmospheric sealing of frozen products, but can also undertake modified atmosphere traysealing for extended shelf life.
