A cheese dairy from the Netherlands has been making a variety of finest-quality cheese products since the early 19th century, and has meanwhile made a name for itself as the leading Dutch brand world-wide.
A solution for reducing, pumping and plasticizing young to medium-aged cheeses has been found by using the KNOLL type MX50R-60/30 progressing cavity pump in combination with a frozen block cutter.
The firm to very hard blocks of cheese, which weigh as much as 30 kg, are reduced to a pumpable size of 25 x 35 x 20 mm by the reducer and conveyed through a feed hopper adapted to match the frozen block cutter outlet, and directly into the MX pump system.
The feed screw on the feed hopper pump has a special non-stick coating which prevents cheese from sticking to the feed screw and so provides for a smoother conveying process.
This coating has other advantages too, as it allows the feed screw to be cleaned more quickly and easily.
Plasticizer plates built into the discharge nozzle or at the end of the pressure line shape the cheese into narrow strips, thus speeding up and simplifying subsequent processing. The Even Wall® geometry is a key factor here because it allows pressures of up to 80 bar to be used.
