KEN DW 410
Subject to alterations
The risk of harmful corrosion in the first case is considerably reduced or
entirely eliminated if molybdenum alloy stainless steel is used. In case 5, the
surface will become brownish, which does not mean anything to the surface
of the steel apart from the cosmetic appearance. In cases 2, 3 and 4, the
surface of the stainless steel will be discoloured. This occurrence of rust will
occur most frequently on horizontal surfaces in the machine and may often
be felt with the tips of ones fingers. Small particles will set off a small rust
spot that will not normally harm the steel. Larger items (hair needles,
roasting chucks, coins, capsules, etc.) also set off rust colour on the surface
of the plate, but also makes it possible for a very aggressive environment to
develop between the item and the plate. Under these unfavourable
conditions, strong hydrochloric acid forms that is always harmful to the
material. It is thus important to clean the machine every day of deposits of
any type. If necessary, cleaning can be done with a sponge (not one
containing iron) and foam powders, etc.
1. Make sure any water treatment facility is always ok. A defective facility
may segregate salt to the machine and thus harm the machine.
2. Make sure the machine is cleaned daily and aired. Soap residue, food
residue, iron particles, etc., may damage the machine in the longer term.
3. Never wash items soiled with iron particles without cleaning the machine
immediately after.
4. Make sure to make correct soap dosage, particularly if you do it manually.
If the machine has an automatic system, the soap dosage should be
checked regularly. The check should be made by the soap supplier when
he is there anyway, or you can do it yourself by making a simple pH
measurement (litmus paper). Ask your soap supplier.
5. Use only types of soap that are intended for machine washing and
preferably types with material-protecting substances added.
6. Always comply with the dosing regulations and safety rules.
See the soap suppliers datasheet.
7. Never try to decalcify or clean the machine with hydrochloric acid, etc.,
without expert assistance. Use products approved for the purpose.
Ask your soap supplier.
Daily cleaning with water removes dirt and prevents corrosion attacks from
getting a foothold.Washing is best done with a sponge and hot water or with
a mild cleaning agent, followed by washing with cold water. Remember to
clean the bottom of the wash tank in particular.
The appearance of the surface can be further enhanced if you use a wrung
piece of cloth or chamois at the end.
There are also a number of oil products on the market for surface treatment
of stainless steel. Ask your soap supplier.
