To clean crockery effectively commercial dishwasher will use set washing cycles in parallel with measured dosing of specially designed dishwasher detergent and rinse aid. Most commonly these products are sold in 5-litre bottles.
How the chemical work in the dishwasher
Dependant on the make and design of the dishwasher, generally the chemical is taken into the machine using a chemical pump found inside the machine, this ensures the precise amount is drawn from the bottle and used for washing. Dosing levels are usually adjusted by the engineer setting up the dishwasher (this process is called commissioning).
Different chemicals have varying concentrations which is why you should always read the dosing instructions written on the bottle if you are going to try adjusting the dosage yourselves. Also, some commercial dishwashers require a specific chemical to wash and its optimum capacity, for example, Enviro clean pro glasswashers need to be used with Enviro clean glass wash treatment to ensure glasswasher can clean properly and protect machine components which may be susceptible to degradation from improper chemicals.
Types of Dishwasher Chemicals
This essential chemical quickly stains, grease and oil from your tableware. Made with surface active agents or surfactants which help to separate the dirt and grease particles from the surface which is then washed away by the dishwasher jet arms spraying water. Some detergents feature caustic soda which reacts with fat particles to remove burnt on food and grease.
Found is some dishwashing detergents, rinse aid is a surfactant tension of water. Rinse aid prevents water from forming into droplets and instead encourages it to drain from the surface.
Descaling agent is a chemical substance used to remove limescale from metal surfaces that come into contact with hot water. Descaler is typically acidic in composition that reacts with the alkaline carbonate compounds present in scale. The chemicals are normally very corrosive and must be handled with care using the correct PPE.
These substances are capable of eliminating microorganisms including those bacteria which cause food poisoning and other diseases. The numbers of microorganism are reduced to a level that does not compromise the safety of any food that comes into contact with the surface of the plate or serving ware.
