With an investment of € 200 million, Hochwald has built
a greenfield plant for 800 million kg milk throughput in
Mechernich, Germany (photo: Hochwald)
Raw milk reception/tank farm
Five reception lines are provided for the raw milk intake. Lanes
1 to 4 operate separately, each with a capacity of 60,000 l/h; the
cooled milk goes to the raw milk tank farm. Lane 5 is used for the
delivery of cream and can also be used as an output line with a
capacity of 40,000 l/h. The milk is cooled in the milk tank store.
Six coolers, 30 pumps and 320 automatic valves are installed.
All tanks were designed and installed in such a way that emptying
in free fall is possible without pumps. The stainless steel tanks
were supplied by Roth and HBB/KKS.
Processing, mixing station
Raw milk is standardised, cleaned and/or pasteurised via two milk
heaters and two separators with a line capacity of 50,000 l/h each
and conveyed to the tank farms.
Pasteurised milk is processed into milk beverages via the mixing
station by adding various dry substances and other additives. The
finished batch of milk-mix is then pumped to the UHT department.
Milk is also standardised in a special tank farm and concentrated
into skimmed milk concentrate or condensed milk via the
evaporator. The skimmed milk concentrate can then be used for
further process steps or pumped to the output. The condensed
milk is made available for the UHT process via another tank farm.
