Cleaning removes product residues and deposits, such as proteins, resins, oils, organic and inorganic salts, and micro-organisms from the surfaces of vessels.
Primarily, cleaning with pressurised water, as used in movable spraying devices, is of great importance for through cleaning of appliances such as valves, which are not included in a CIP circuit and cannot be cleaned in a caustic bath.
Cleaning agents are avaiable in various forms nowadays (powder, pastes, liquids). In general a liquid form is prefferd since the medium is then easier to handle and can be dosed more easily.
Depending on their pH they are classified into: alkaline, acidic and neutral cleaning agents.
Alkaline cleaning agents are predominantly based on 60 to 80% caustic soda with additions of sodium carbonate, metasilicate, polyphosphates, trisodium phosphate, wetting agents and inhibitors.
Acidic cleaning agents are based on phosphoric acid, sulphuric acid, nitric acid or citric acid with the addition of inhibitors.
The following properties are required of a chemical cleaning agent: high solubility in water, good cleaning power, effective at low temperatures, no foam formation, no deposits, no reaction with salts in the water, easy to use, low costs.
A surface from chemicales is obtained by the disinfecting effect of chemicals and sterilisation by heat treatment. Depending on their pH they are classified into: acidic, neutral and alkaline disinfecting agents.
Preffered disinfectants are: halogen containing disinfecting agents (sodium hypochlorite, chlorine dioxide, chlorine gas); oxidants (peracetic acid); quaternary ammonium compounds and amphoteric tensides.
The cleaning and disinfecting agents we offer are made by the german company TENSID CHEMIE GmbH.
