Follow the hints of Città d’Italia – Caffè La Messicana Piacenza for the correct maintenance of the professional coffee machine.

COFFEE MACHINE MAINTENANCE

The cleaning of the machine, with specific products, is an important aspect for hygiene issues, for the best equipment performance, but also for guaranteeing the taste of the coffee blend.
Some simple maintenance rules:

• The coffee machine must always be switched on.
• The displacement pressure and the water temperature must be monitored using the reference gauges.
• Daily cleaning of portafilters, filters and showers
• Checking the water softener.

GRINDER MAINTENANCE

The grinder is an essential element for the coffee bar activity as it grinds coffee into the suitable size and doses it in the right quantity. Therefore, in order to keep the organoleptic qualities of the coffee intact, it is important that the grinder is always clean. Here are some hints for the correct maintenance of the grinder:

• The grinding blades must be correctly adjusted to ensure a perfect coffee extraction.
• If the grinding is large, the water will encounter less resistance in crossing it and therefore less substances will be extracted. On the other hand, fine grinding implies a greater resistance and the contact time is greater. So that, more substances are extracted.
• Checking the coffee grinding every day, considering also the environment. If there is humidity, the coffee particles are wrapped in water molecules and these are less permeable. Therefore a greater grinding would be better. On the opposite side, in dry environments it is preferable to reduce the degree of grinding.
• The grinder blades must be replaced regularly as they are subject to wear.
