Bosch MUM4 (MUM4405)

The Bosch MUM4405 is a household MUM4 planetary mixer with a 3.9 L plastic bowl, a 500 W motor and four speed settings. The multifunction arm accepts a dough hook, stirring whisk or beating whisk. Bosch specifies up to 1.5 kg of yeast dough or 2 kg of cake batter for this model. A transparent lid with a filling opening is included. Bosch lists the MUM4405 as no longer available; the current Series 2 uses the separate MUMS2 platform.

How the calculator uses this mixer

Water temperature. Pandough uses the typical friction factor for its type, 12. To reach 24°C dough in a 22°C kitchen, the calculator asks for water at 14°C, against 24°C when mixing by hand.
Batch size check. At 60% hydration, the calculator flags batches over 1.5 kg. For a 50% biga, the limit drops to 1.1 kg.
