WEIMA-PUEHLER PUEHLER E.200 drainage and compressing device for packaging and cans

When food and beverage products are recalled or incorrectly labelled or filled, the waste is often sent to landfill for disposal. However, WEIMA-PUEHLER compressing technology can provide a solution to this issue. Cemac Technologies has partnered with WEIMA to bring this technology to Australia and will display the PUEHLER E.200 at foodpro 2023.

With a low investment cost, the WEIMA-PUEHLER can de-water, de-package and compress packaging and cans in one compact machine. Drained contents can be saved for re-work and compressed recyclables sent for processing — allowing users to save on waste disposal and meet sustainability targets. The unit can be installed and customised for any production line. With the recovered output, high-quality goods can be produced again.

The unit requires minimal energy for a throughput of up to approx. 3000 cans/h of 330 mL can size using double-pump hydraulics. It is made from high-quality stainless steel to protect the machine body and the control cabinet from wear and corrosion while simultaneously remaining low-maintenance and hygienic. Installation only requires a water connection and is designed for minimal downtime thanks to hydraulic oil cooling using the heat exchanger method. This is more hygienic and doesn’t need cleaning. The water can be repurposed to dilute extruded material and minimise foam development.

The PUEHLER machine uses gentle perforated rollers to pierce packaging to avoid bursting. The individual sieve sizing that separates mass from packaging can be configured from 4–12 mm. Clean, dimensionally stable discs are created between the press ram and slide plate and require no conveyor as the curved discharge tube can be extended up to 5 m to allow material to fall directly into a container with no belt. The press has five maintenance hatches for easy service access and cleaning. The discharge tube can also be equipped with a post-cleaning device for more pure output discs. Using the Siemens PLC control panel, parameters such as pressing time, pressing force or re-pressing can be adjusted.

The unit is suitable for all kinds of packaging applications including plastic bottles, liquid paper boards, aluminium cans and more.
