Abstract
Abstract A method and apparatus for making bread wherein the duration of kneading is set at a predetermined value, and the kneading stage is divided into (1) an early kneading stage wherein either cool or warm air is blown onto the dough at the start of kneading to bring the dough temperature, within a short time period, close to the optimum kneading temperature and (2) a later kneading stage wherein cool air and warm air are blown onto the dough in an alternating mode in order to maintain the dough temperature close to the optimum kneading temperature.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
215 words
An apparatus for making bread comprising: an oven provided with oven heating means; a vessel internally disposed in said oven for receiving bread materials; kneading means comprising a rotary vane internally disposed at the bottom of said vessel; a temperature sensor disposed inside said vessel; a heater-equipped blower capable of switching between blowing warm air or cool air, said heat-equipped blower being provided with means for conducting air blown by the heater-equipped blower to said vessel; and a control unit for controlling the performance, in a sequential order, of a kneading step wherein the bread materials are kneaded into a dough, a fermentation step in which the kneaded dough is fermented, and a baking step in which the fermented dough is baked, wherein said control unit comprises means for setting a predetermined duration for the kneading step, means for comparing the temperature detected by said temperature sensor to a predetermined optimal kneading temperature, and means for activating said heat-equipped blower to blow cool air into said vessel if the detected temperature is higher than the optimal kneading temperature, and to blow warm air into said vessel if the detected temperature is lower than the optimal kneading temperature, and means for terminating the kneading step at the end of the preset duration for the kneading step.
Claim 2
Independent Claim
215 words
An apparatus for making bread comprising: an oven provided with oven heating means; a vessel internally disposed in said oven for receiving bread materials; kneading means comprising a rotary vane internally disposed at the bottom of said vessel; a temperature sensor disposed inside said vessel; a heater-equipped blower capable of switching between blowing warm air or cool air, said heat-equipped blower being provided with means for conducting air blown by the heater-equipped blower to said vessel; and a control unit for controlling the performance, in a sequential order, of a kneading step wherein the bread materials are kneaded into a dough, a fermentation step in which the kneaded dough is fermented, and a baking step in which the fermented dough is baked, wherein said control unit comprises means for setting a predetermined duration for the kneading step, means for comparing the temperature detected by said temperature sensor to a predetermined optimal kneading temperature, and means for activating said heat-equipped blower to blow cool air into said vessel if the detected temperature is higher than the optimal kneading temperature, and to blow warm air into said vessel if the detected temperature is lower than the optimal kneading temperature, and means for terminating the kneading step at the end of the preset duration for the kneading step.
