Maintenance and cleaning
Hygienic wash down
¾ Wipe off and remove large and loose particles.
¾ Pre-clean with water (20 bar, 55 °C).
¾ Point the spray nozzle downwards towards the surface at an angle of 45°.
¾ For extra cleaning use a soft brush around seals, grooves and crevasses.
¾ In severe cases use a soft brush and/or plastic scraper in combination with
the water spray.
¾ Clean with cold alkaline or acid agent for approximately 15 min.
¾ Wash off with water (20 bar, 55 °C).

¾ Inspect surfaces, grooves and crevasses for residues after cleaning.
Risk of damage to the Drum Motor due to improper
cleaning
¾ Never use an acid cleaning agent in combination with a
chlorine-containing agent because dangerous chlorine
gasses can develop, which can affect process
equipment such as stainless steel and rubber parts.
¾ Do not use acid agents on aluminium or galvanised
parts.
¾ Avoid temperatures above 55 °C to prevent proteins
sticking to the surface.
Remove fats with lower temperatures and proper
cleaning agents.
¾ Avoid water pressure above 20 bar to prevent aerosol
contamination.
¾ Allow 30 cm between the spray nozzle and cleaning
surfaces.
¾ Do not point and hold the spray nozzle directly at
labyrinths and seals.
Hint
• If lime deposition takes place, an acid cleaning is advised 1 to 4 times a
month.
• If the use of chlorine is approved, cleaning with an alkaline cleaning and
disinfection agent is advised. In this case, depending on the degree of
contamination, the final disinfection step can be skipped.
