What the Boerger Multichopper is used for


Waste food chopping

A food recycling company disposes of used cooking oil, kitchen and food waste, out-of-date food products from the catering trade and frying oil. The prepared food waste can be used as a raw material for the production of biodiesel or to produce environmentally-friendly energy from biogas plants in the form of electricity and heat.

The food waste is coarsely chopped by a hammermill. To reduce the remaining solids in the liquid medium even more before they enter a centrifugal separator, the customer has incorporated a Boerger Multichopper plus.

The Multichopper plus is equipped with the automatic Mechanical Cut Adjustment unit. The MCA unit ensures optimum cutting performance at all times. 

The efficiency of the downstream centrifugal separator could be increased as a result of the excellent chopping yield.
