Heat sealing specialist Proseal has introduced a new tray sealer specifically designed to handle very large food trays.

The new Proseal GT5exSD can seal trays up to 400mm wide, making it ideal in particular to handle large cuts of meat and joints. Top speeds for the single lane machine are up to 40 skin pack trays per minute.

The GT5exSD is fully flexible and adaptable to handle any type of packing operation, including MAP gas flushing, Vacuum MAP sealing, skin packaging below and above the flange, and Skin Deep. Customers can simply select the format types they require and these can be added to or taken off at any time. This allows food manufacturers to change their pack formats in line with customer demands without having to invest in new equipment.

Maximum throughput is achieved thank to Proseal’s Pro-Motion system, which uses following motion and intelligent buffering technology to enable trays to feed continuously into the sealer without stopping. An auto-detect product flow monitoring system regulates the speed of the infeed conveyor according the amount of trays being supplied. This typically increases speeds by up to 30%.

Proseal’s E-seal® technology meanwhile provides high quality seal reliability to meet the stringent quality requirements of the food retail sector while delivering a 92% reduction in energy usage, which offers valuable cost savings and sustainability benefits.

Equally important, the machine boasts the most hygienic design of any tray sealer with rapid strip down of the product handling conveyors allowing deep cleaning to be carried out quickly and easily.

Another advanced feature of the GT5 range is its Pro-Tect user login security system, which provides different levels of authorisation access for individual personnel. The system keeps a log of information inputted for full traceability in the event of any problems, and any attempt to log in above a person’s level of authorisation will also be registered and recorded.

The GT5 retains Proseal’s renowned rugged construction to food industry approved hygiene standards with full wash-down protection. The company’s established ‘Auto Tool’ connection system enables tool changes to be carried out in around five minutes, while downtime is further minimised by the use of quick-change conveyor belts, and an auto-lock film reel holder.

The retention of valuable pneumatic functions means the machine can also offer additional benefits such as date coding of pre-printed film.
