Abstract
Abstract A method of proofing and baking bread in metal pans using microwave energy as described. Overall proofing and baking time are reduced by a method combining conventional and microwave proofing of the bread loaves prior to conventional and microwave baking. Significant reduction in processing time results when the bread is conventionally and microwave proofed and conventionally and microwave energy baked.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
224 words
A method for processing bread comprising the steps of: forming a plurality of one pound loaves from a bread dough mixture; placing each of said plurality of loaves in a different one of a plurality of metal baking pans; partially proofing said plurality of loaves in said baking pans in a hot air oven at 85° F. to 120° F. with a relative humidity of 40% to 85% for a first time period of 20 to 40 minutes; finish proofing said partially proofed plurality of loaves utilizing microwave energy having a frequency equal to 915 MHz and 2450 MHz simultaneously, a power of 75 to 107 watts per pound loaf divided between said two frequencies and a flux density of from 5 to 10 watt hours per pound for a second time period of 3 to 10 minutes; and baking said finish proofed plurality of loaves in a combined hot air and microwave oven at an air temperature of 415° F. to 440° F. and with microwave energy having a frequency equal to 915 MHz and 2450 MHz simultaneously, a power of 50 to 100 watts per pound loaf divided between said two frequencies and a flux density of from 5 to 10 watt hours per pound for a third time period of 11 to 13 minutes to achieve bake out and crust color.

Claim 3
Dependent Claim
42 words
A method according to claim 1, wherein said first time period is 30 to 35 minutes, said second time period is 3 to 6 minutes, said air temperature is 415° F. to 425° F., and said third time period is 12 minutes.
