Thermochromic ink for higher retorting safety

A thermochromic ink that changes colour at high temperatures offers food manufacturers a more reliable coding method, with a more obvious indication of correct sterilisation of canned products. Designed for retort sterilisation of filled cans, Markem-Imaje's MS596 thermochromic ink changes from black to blue when the can reaches the correct temperature of between 115 and 125 deg C. Giving good...

Spring pressure gauge for beverage seamers

A can gauge used to measure the spring pressure of lower lifters during seamer set-up has been released by Imeta, which has been designing and producing seaming chucks and rolls, changeover kits and spare parts for seaming machines since 1963. The gauge is said to be suitable for any seamer, since the measuring station is smaller than a slim 202...

Process skids make for easy heat exchanger systems

Modular skid-mounted heat exchangers for pasteurisation, cleaning-in-place (CIP) and other heating and cooling applications have been developed by HRS Heat Exchangers. With this approach, the processing system is contained within a frame, which makes it easier to transport and install. Individual skids can contain anything from a single heat exchanger and ancillaries to complete and complex systems where the skid...

Skewed sheet detector prevents weld problems

The detection of skewed or rotated three-piece can blanks has been improved with Innosen’s latest sheet skew measurement system. Misaligned sheets cause poor coating placement, which leads to wire breakage in the welder, damage to weld rollers or poor-quality welds. This further results in spoilage, downtime and customer complaints due to poor quality products. Replacing the IS415, the more robust IS416...

Safe magnetic separation of steel canstock sheets

A ‘fail-safe’ sheet separator has been developed by Goudsmit Magnetics to provide automatic separation of steel sheets in gauges up to 4mm. The separator is equipped with powerful neodymium magnets and can be switched on and off using a patented system, in which the magnets are rotated pneumatically. It overcomes the problem of lubricated tinplate sheets adhering and causing damage...

Improvements to lug cap safety button inspection

Indian canmaker Shetron Ltd has improved the way it tests the safety buttons on lug caps by replacing analogue systems with digital technology. Prediction of the performance of safety buttons – their ability to pop in and out – after jar filling and capping at the customers’ premises needs to be confirmed during cap manufacturing. Previously, this was done during production...

Versatile twist cap forming and lining machine

A newly-developed forming and lining machine for twist-off caps is said to be the most versatile in CepedaMeltog’s range. The T300 features the four operations of calibration, pre-curling, lug forming and compound lining that are needed to make high-quality twist off caps. However, with higher output – up to 400 caps per minute – fewer cap forming units are required. CepedaMeltog’s...

High output closure lines with quick changeover

The Kappa series of sheet-fed presses and the Gamma III cap forming systems have been upgraded by Blema Kircheis to meet the more demanding requirements of closure manufacturers. On the compact two-metre-high Kappa portal press the underdrive uses an oil bath that is beneath and on the sides of the press. As a result, oil spillage onto the closure shells...

100% recycled plastics for multi-pack carriers

Multi-pack carriers for cans made entirely from recycled plastics will be launched by Scotland-based company WaveGrip next year.  Recyclable through polyethylene (PE) film collection schemes and weighing less than 4g for a standard six-pack, WaveGrip, now contains 50 per cent Sustane NXG post-consumer recycled (PCR) polymer. However, the Greenock-based company plans to increase the amount of PCR in WaveGrip carriers...
