Components in stainless steel for coffee machines: no lead, no problems!

While in the Coffee industry the OT57 brass is largely used for the machines, it is increasingly catching on the use of stainless steel for the hygienic characteristics that distinguish it.

The result in the cup is much cleaner and the metal taste, that inevitably is present in some older machines or on which you have not done proper maintenance, is absent.

The passage in stainless steel demand is steadily increasing by customers from around the world, eager to reduce the need for pickling of the components, ie the chemical removal of the oxidized surface layers or contaminants by acid or alkali solutions. The pickling necessary for the removal of rust from the machine makes the treated surfaces in fact extremely porous, losing the characteristics of hygiene required.

The steel, tested to withstand temperatures up to 300 ° C is highly resistant to water, water vapor, moisture, food acids and organic and inorganic acids and has a superior durability while requiring a reduced maintenance compared to other metals.

Numerous tests have shown a degree of cleanability similar to glass and porcelain even after several automatic cleaning cycles and is one of the few metals added in the decree of 21 March 1973, adopting the "hygienic discipline of packaging, containers and utensils intended to come into contact with foodstuffs or with the use of food substances ".

The R & D department of Nuova Ricambi is working more with lead-free materials and has developed several components in stainless steel, including filters, blind filters and filter holder for all major manufacturers of professional espresso coffee machines.

Special attention was given to stainless steel solenoid valves, for which we selected the company Sirai as a partner (solenoid valve 2 ways  and 3 ways), and the company Parker with three new products on catalog: the 2-ways solenoid valve, the 3 ways and the 3 ways - 24 volts.

Concerning stainless steel pumping, we  have on catalogue the Faema small pumping  and the strapseal procon pumping with clamp to all the other machines.
