Leading designer and manufacturer of process automation systems Key Technology has redesigned packaging system AVSealer to feature a new ‘true temperature’ control and CE mark.

The redesign assures superior sealing consistency and meets the highest safety standards.

Ideal for small- to medium-sized produce packers, the semi-automatic packaging machine heat seals a variety of bag sizes with or without a vacuum and has an optional gas flush cycle to maximise production flexibility and satisfy the demands of a wide range of fresh-cut applications - all on one system.

The AVSealer’s new ‘true temperature’ control assures a consistent sealing temperature to maximise package quality by eliminating “burn through” and seals that do not hold. The new temperature control also reduces energy use and allows for faster heat sealing. Bags up to 470mm wide can be sealed with the AVSealer at a rate of four to six bags per minute with vacuum and up to eight bags per minute without vacuum.

The AVSealer offers adjustable user programs that set the vacuum pressure, gas flush, heat sealing temperature and seal time to consistently package a wide range of products including wet and dry lettuce, cut vegetables, fruit, fresh herbs, as well as other small produce. The AVSealer can be switched over to handle different products and different bag sizes, with no tools, changeparts, or mechanical adjustments. Simple controls and adjustable user programmes enable operators to be trained quickly.

Designed for ease of use, bags and controls are ergonomically placed for easy operator access - no lifting of a cover, lid, or sealing bar, just push a button and seal the bag. Special order rack-mounted floor stands are available from Key Technology for one, two and four machine heads or a single bench configuration.

The PLC-controlled AVSealer maximises production flexibility, while offering simple operation and consistent performance. Teri Johnson, fresh-cut industry manager at Key Technology, said: “Key is committed to serving the fresh-cut industry worldwide. Continuing to improve the popular AVSealer and introducing a CE-marked version are examples of our dedication to this industry. The redesigned AVSealer is one of a series of developments designed to help fresh-cut processors around the world maximise product quality and food safety, while improving operating efficiencies.”
