Hygienic ice production

EU legislation considers water and ice being food and ice producers are responsible for complying with the applicable hygiene regulations. Due to its "Hygienic Design" of our ice machines, along with practical advice ZIEGRA provides the means to meet the prescriptions of ice hygiene.
Germs, lime scale and minerals can nevertheless get into the machine and may increase growth of bacteria by stagnant water in water supply, or in the machine (when ice production has been switched off).


THE BENEFITS of ZIEGRA ice machines: 


  • Closed water circuit 
    A small, sealed water chamber, short pipes and the closed ice cylinder prevent most bacterial contamination.
  • Higher operational safety and lower maintenance and service costs
    due to clean water pipes, evaporator surface and valves.
  • Besides the high quality of our machines and the ice, we specially care for hygience at ZIEGRA.

Hygiene options


for your water and your ice machine:

  • Water Filter:
    with activated carbon, with coarse and fine filters as well as lime stabilizers to actively prevent a breeding ground for germs inside the ice machine, but also to extend its life expectancy.
  • UV disinfection: :
    germs which get into the machine through the water pipes are killed before ice production starts
  • HygienePLUS: automatic water drain
    to prevent stagnant water at standstill of machine.
  • HygienePLUS: automatic flushing
    of all water conducting parts.
  • HygienePLUS: flushing with disinfection
    for all water conducting parts.
  • Hygiene Set
    for water conducting (and possibly scaled) parts. Easy to exchange and reasonable in price.
  • Special solutions for highest hygiene requirements.



Please always consider where the ice machine is installed. When the ice is discharged from the ice cylinder it is exposed to the ambient air which by air circulation also holds external germs. Therefore  the ice machine should be installed in a place as clean as possible. From a hygienic point of view storage or garbage rooms, and places in the vicinity of transport paths are not appropriate, whereas processing rooms and cooling rooms with organic products are suitable only to a limited extend.
