2.3. Specification for the measurement of the coffee products temperature.
The temperature is influenced by the flow from the dispenser and stratification of temperatures in
the glass. In order to consider these phenomena and to introduce measures that allow comparisons
in controlled conditions, below guidelines must be followed:
Conditions:
a) Water temperature in tank: 23°C (+/-2°C).
b) It must be used a plastic cup (see picture N°1).
c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2).
d) The coffee machine is tested without any change of parameters or calibrations, which may
affect the temperature of products, so the measurement of temperature must be done with
machine in default factory setting.
Procedure:
1. The temperature must be measured in the cup, immediately after dispensing. Cup has to be
placed on a non-metal surface using a thermocouple thermometer (Picture 1).
2. The temperature in the cup is measured by immersing the probe of the thermometer up to touch
the bottom.The probe then must be moved in a circular motion for 5/6 rotations. At the of the rota-
tions, stop in the center of the cup (Picture 2).
3. The highest temperature measured during the rotations is the value we are searching for, and
that must be reported;
4. Test measurement: from end of dispensing to the end of rotations must be completed within 12
seconds.
5. the distance of the probe from the bottom of the glass is a function of the quantity of coffee dis-
pensed: 10mm for 35gr - 17mm for 60gr - 35mm for 120gr and superior (Picture 3).
Limits of acceptability
The acceptance limits are divided by features and products and are the following:
Espresso Coffee Italy Q.ty 25/40 gr.
Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C
Coffee Q.ty 70/120 gr.
Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C
