Separating and compacting dairy products

Dairies destroy returned goods such as yogurt and other dairy products with expired date and faulty manufacture.


RUNI screw compactor handles both destruction, emptying and compating in one process, and both handling and storage at the manufacturer is saved. Placing the compactor close to the production increases the certainty of destruction and saves transport cost.

During separation the waste stream is split into two. The liquid can either be diverted as waste water or collected and sold for other purposes like energy production or animal feeding. The solid material is so dry that it can either go to incineration at lower cost or sold for recycling.

The material can be fed into the machine manually or with conveyor belt. The liquid is pressed out through a suitable hole matrix and the solid part is slowly pushed out of the departure tray.

The hole matrix is made of stainless steel (AISI316) which is able to resist low ph values.

In the food industry the machine must be isolated from the main production. RUNI has several solutions for this. Demands regarding cleaning of the machine may also be an issue - again RUNI has more solutions.
