The coffee is marketed in different forms:
This is the raw material purchased directly by the consumer.
The beans undergo a grinding process.
The grinding point of the coffee (its grain size) varies depending on the type of preparation and pressure through which the water extracts the beverage:
• Espresso: fine grind (9 bar pressure)
• Moka pot: medium grind (0.6 > 0.8 bar pressure)
• Filter: coarse grain grind (gravity force)
Soluble and instant
This is the dry product obtained by means of water extraction from roasted coffee beans and subsequent dehydration.
There are two main technologies for producing soluble coffee:
• Freeze-drying: the extracted coffee is processed by freezing and vacuum packing
• Dry Spray: the extracted coffee is sprayed into an evaporation channel, sold in sachets and ready to be dissolved in water or milk.
This is the packaging system with pre-set doses and an exact pressing point in order to prepare a cup of coffee with a capsule or pod.
