Separation and Compaction of Tetra-Pak

Separating and Compacting Tetra-Pak

Breweries and other manufacturers of beverages in Tetra-Pak, like juice, soft drinks, smoothies, and other products, often have to destroy returned goods with expired dates and/or faulty products to avoid them being resold by mistake. The RUNI screw compactor is the perfect machine for dewatering Tetra-pak.

The machine handles both destruction, separation, and compacting in one process; this saves manufacturers from storage and handling problems. Installing this compactor close to the production area increases the certainty of destroying faulty products and saves a lot of transport costs.

How Does the Screw Compactor Dewater and Compact Tetra-Pak?

When separating the liquid, the waste stream splits in two. The separated liquid can be discarded as wastewater, or in some cases, it can be collected and sold for other purposes, like being used in energy or animal feed production. After compacting, the solid becomes dry and can be sent to incineration at a lower cost or sold for recycling.

The full Tetra-Paks can be fed to the screw compactor manually or with a conveyor belt. The liquid is squeezed through a perforated matrix, and the compacted packaging material is then slowly pushed out of the departure tray and can be collected in containers.

RUNI Solution for Tetra-Paks

For dewatering and compacting Tetra-pak, we offer two sizes of screw compactors: 

The SK240 Screw compactor. With a capacity of approx. 5.000 liters per hour.
The SK370 screw compactor. With a capacity of approx. 15.000 liters per hour. 

The perforated matrix is always made of stainless steel to withstand liquids with low pH.

Note: In the food industry, the screw compactor needs to be placed away from the primary production - RUNI has several solutions for this. Sometimes cleaning of the screw compactor is essential - also here RUNI has several solutions.
