Peco launches Cryotech’s New UltraClean Dosing System

The three Cryotech dosing systems (CryoDoser, UltraDoser 850 and UltraDoser 350) are now available in 316L stainless steel. They are supplied with a fully encased dosing head known as the ‘EP’ which facilitates wash-down with aggressive cleaning agents, with no detrimental effect on the dosing system.

Peco Nozzle Pre-Cool eliminates soft bottles

This system was launched last year and is working out well with clients.

When a production line is stopped, the small nozzle inside the dosing system warms up due to atmospheric temperature. This means that when the line restarts, a small amount of liquid nitrogen re-cools the nozzle. This in turn, results in slightly less than the target amount of liquid nitrogen being delivered to the bottle and consequently, the first few containers have a slight lower pressure than the following bottles.

This problem is resolved with the use of the new nozzle pre-cool system.

More consistent dosing

Cryotech’s new, improved control systems are enabling our customer to benefit from more consistent dosing.

Bottle pressures of +/- 1 psi (0.07bar) are being achieved at full line speed.

Grant Booth, of the Peco Service Team, explains:

"The ability to change the amount of liquid nitrogen dosed at varying production speeds, gives us more control when commissioning a dosing system. Coupled with the detailed information provided by the encoder, we can set the dose exactly where we want it and adjust it as the filler speed changes.

Originally these units were set up by eye but now, by using a high speed camera, we are able see the dosing process and note how it changes with the filler speed.

With the new controllers we have the adjustment which allows us to provide these accurate bottle pressures."
