200 mm pressed blocks

The WEIMA G.200 is a high-performance dewatering press designed for the professional processing of food, beverage and cleaning product packaging, as well as a wide variety of containers. As a modern, high-performance solution, it combines efficient liquid separation with reliable material compaction – ensuring maximum volume reduction and optimal recyclability.

With a throughput of up to 6 m³ per hour and a compression rate of up to 99%, the G.200 produces compact bales with a diameter of 200 mm. The residual moisture content ranges between 3 and 30 per cent, depending on the input material. The result is manageable, transport-optimised bales that are ideally suited for downstream recycling and recovery processes.

Whether in retail, food production or waste management and recycling facilities: the WEIMA G.200 enhances the cost-effectiveness of your waste management logistics, reduces disposal costs and lays the foundation for a clean, efficient circular economy.

Product features

Due to increased discharge and customisable discharge length

The length of the discharge chute can be extended individually up to five metres. Unlike a screw press, the WEIMA press’s higher discharge point means that no conveyor belt is required for unloading into a container or tipping skip. This allows the press to be positioned optimally to suit your space requirements.

Hoppers for every application

You can choose from a range of hopper capacities: 220 l, 600 l, 800 l, 1,200 l or 2,000 l. In addition, a manual or automatic hopper lid can be fitted to ensure safety and hygiene.

Welding seam according to hygienic design

Perfectly hygienic thanks to the optional hygienic design

Safe and hygienic. Thanks to their easy-to-clean design, WEIMA dewatering presses ensure food safety, meet hygiene standards and simplify cleaning procedures. This helps to minimise downtime.

Made possible by hydraulic oil cooling

It can be used without any problems in automated multi-shift operation. Thanks to oil cooling via a heat exchanger, the hydraulic oil can be kept at a constant operating temperature without overheating.

User-friendly touchscreen for quick parameter changes and diagnostics

Parameters such as pressing force and time, or the re-pressing function, can be set intuitively via the Siemens control system with touch display. Precise diagnostic messages ensure minimal downtime. Furthermore, full integration into the PROFINET system is possible. This allows upstream and downstream systems, such as conveyor belts or a lifting and tilting station, to be controlled in a user-friendly manner.

For maximum durability

To ensure the G Series remains in service for many years, we use high-quality stainless steel. This protects the machine body and control cabinet from wear and corrosion, whilst also being low-maintenance and hygienic.

Automated liquid drainage thanks to liquid level detection in the sump

If required, the removal of liquids can be automated using level sensors in the product collection tray. The Liquiphants control the pumping out of the extruded material and automatically shut down the recycling press if downstream processes are at a standstill. We use screw pumps for the removal of paste-like liquids and centrifugal pumps for liquid materials.

Clean pellets thanks to the post-cleaning system

To rinse any remaining product residue (e.g. yoghurt) off the moulded parts, a post-cleaning device in the form of spray nozzles can be fitted to the discharge pipe. The cooling water from the oil cooling system can be used for this purpose.

Thanks to the horizontal agitator

A horizontal agitator can be fitted to the feed hopper as an option. The continuous agitation of the material prevents bridging in the hopper, thereby ensuring a constant feed of material.

Custom mesh sizes for all types of packaging

The walls of the pressing chamber are perforated to allow the drained liquid to flow out. The screen aperture size can be individually adjusted to suit the properties of your material. For paste-like materials such as yoghurt or quark, round holes up to 12 mm in diameter are generally used. For liquids, however, screen apertures as small as 4 mm are possible. In any case, it is important that small packaging fragments do not end up in the collection tray along with the liquid.

Automated operation on your production line

To enable the press to operate fully automatically, the feed hopper can be fitted with a level sensor. This allows upstream systems (conveyor belt) to be stopped or started automatically as soon as the hopper reaches its maximum capacity. A continuous flow of material prevents the hopper from becoming overfilled.
