Friction Factor (Ff) Friction Factor

Friction Factor Definition

The friction factor is a value expressed as temperature, representing the amount of frictional heat imparted to a dough by a particular machine.

The equation for friction factor is dough temperature multiplied by 3 minus the sum of the flour temperature, room temperature, and water temperature. 

For example, the friction that imparts a stand mixer, food processor, or bread machine used to mix and knead the dough.

When calculating dough temperature, friction must be considered since it can potentially increase the temperature of your dough drastically.

The problem is that the friction factor varies greatly depending on the combination. This is because combining and kneading bread dough involves several factors.

The heat produced is affected by several variables, including the mixer used, the time and speed of mixing, and the volume of dough in the bowl.
