Recipe build-up

Below an example is given of how a recipe can be built up:

Fig.15 Recipe build-up

The above-mentioned recipe can be fully calculated. See below for an example:
• The coffee volume has been set to 2000ml.
• The quantity of lost water has been set to 10% (the percentage may differ for each coffee
type or the ground of the coffee).
• The machine will now dose a total volume of 2200ml water (2000ml + 10% = 2200ml).
Now it is known how much water the machine will dose and the various programmes can be used
for this.
• Pre-infusion has been set to 500ml.
• P1 has been set to 400ml and to 4x dosing (therefore here 4 x 400ml = 1600ml will be dosed
with a set interval of 10 seconds between the 4 dosings).
The machine will now dose 500ml (Pre-infusion) + 1600ml (P1) = 2100ml water on the coffee.
In this example also 100ml will be dosed through the bypass.
2200ml (total volume) – 2100ml (set dosed volume) = 100ml.
The 100ml. (for the bypass) will be dosed in the waiting times.
The water dosing time can also be calculated based on the pump speed and the waiting times.
The correct drip time is to be determined by experience.
The total set time for the coffee = water dosing time + drip time.

Default recipes

A number of default recipes have been programmed in the factory.
These recipes can be used for making coffee immediately after installation.
3 different volumes have been programmed for each recipe.
Of course, the results of these recipes depend on various factors, such as the ground of the
coffee, the quantity of coffee, the roasting of the coffee, etc.
If required, these recipes can be adjusted using the programme "change recipe".
