Cake Batter Flat Beater 20 lbs.
When mixing dough ( pizza, bread or bagels), check your "AR" absorption ratio - water weight divided by flour weight.
Above capacities based on 12% flour moisture at 70°F water temperature. If high gluten flour is used, reduce above
dough batch size by 10%.
Example: If recipe calls for 5 lbs. of water and 10 lbs. of flour, then 5 divided by 10 = 0.50 x 100 = 50 %AR.
• 2nd Speed should never be used on mixtures with less than 50% AR.
• Do not use attachments on hub while mixing.
When calculating the correct size mixer for your application, here are some helpful weights & measures:
• 8.3 lbs. = 1 gallon of water – 2.08 lbs. = 1 Quart.
