Pullup
Pullup
The Pullup curve is designed by having one set heat point and then “pulling” the coffee up to this temperature. It relies on three main factors that must balance each other.
The charge temp,
The volume of beans in the drum
The desired end temp and time.
These three goals are met with one set inlet temperature, which "pulls the bean mass up to the desired end temperature. A pull-up curve can be best thought of as setting your oven temperature like when baking a cake.
The size of the cake, the heat in the oven and the time needed to bake the cake are all achieved by setting the oven temperature. This balance then "pulls up" the cake to the desired temperature, whilst simultaneously allowing for the correct cook time and development.
