Abstract

Abstract Dough mixing for the production of farinaceous footstuffs, in which the energy added in mixing is sufficient to determine the cell structure. There are four essential conditions: the energy added in mixing is not less than 15 watt hours per kilogram of the total ingredients; the rate of energy input is such that the energy is added in not more than 7 minutes; the mixer is cooled by passing a fluid through a jacket surrounding the mixing chamber, and at least one of the sugar and fat ingredients are added part way through the mixing process.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 189 words
A method of mixing dough for use in the production of bread having a specific volume of about 4.5 to 7.0 cubic centimeters per gram and wherein energy added during mixing is sufficient to substantially determine the cell structure of the finished product, the dough, not being a sponge, requiring substantially no fermentation in bulk, comprising the steps of: mechanically mixing the dough in a batch; imparting energy to the dough by said mixing step in a quantity in excess of 15 watt hours per kilogram of total dough ingredients; initiating and completing said mixing step in less than 7 minutes; controlling the temperature rise in the dough resulting from energy input during said mixing step, by passing a fluid coolant through a jacket surrounding the mixing chamber so that the temperature of the dough after mixing is within the range of 25° C. to 35° C.; adding at least one of the ingredients sugar and fat part way through the mixing process but after at least 25% of the total mixing time in the mixing chamber; and carrying out at least part of the mixing under vacuum conditions.
Claim 2
Independent Claim 189 words
A method of mixing dough for use in the production of bread having a specific volume of about 4.5 to 7.0 cubic centimeters per gram and wherein energy added during mixing is sufficient to substantially determine the cell structure of the finished product, the dough, not being a sponge, requiring substantially no fermentation in bulk, comprising the steps of: mechanically mixing the dough in a batch; imparting energy to the dough by said mixing step in a quantity in excess of 15 watt hours per kilogram of total dough ingredients; initiating and completing said mixing step in less than 7 minutes; controlling the temperature rise in the dough resulting from energy input during said mixing step, by passing a fluid coolant through a jacket surrounding the mixing chamber so that the temperature of the dough after mixing is within the range of 25° C. to 35° C.; adding at least one of the ingredients sugar and fat part way through the mixing process but after at least 25% of the total mixing time in the mixing chamber; and carrying out at least part of the mixing under vacuum conditions.
Claim 3
Independent Claim 178 words
A method of mixing dough for use in the production of bread having a specific volume of about 4.5 to 7.0 cubic centimeters per gram and wherein energy added during mixing is sufficient to substantially determine the cell structure of the finished product, the dough, not being a sponge, requiring substantially no fermentation in bulk, comprising the steps of: mechanically mixing the dough in a batch; imparting energy to the dough by said mixing step in a quantity in excess of 15 watt hours per kilogram of total dough ingredients; controlling the temperature rise in the dough resulting from energy input during said mixing step, by passing a fluid coolant through a jacket surrounding the mixing chamber so that the temperature of the dough after mixing is within the range of 25° C. to 35° C.; adding at least one of the ingredients sugar and fat part way through the mixing process but after at least 25% of the total mixing time in the mixing chamber; and carrying out at least part of the mixing under vacuum conditions.
Claim 4
Independent Claim 178 words
A method of mixing dough for use in the production of bread having a specific volume of about 4.5 to 7.0 cubic centimeters per gram and wherein energy added during mixing is sufficient to substantially determine the cell structure of the finished product, the dough, not being a sponge, requiring substantially no fermentation in bulk, comprising the steps of: mechanically mixing the dough in a batch; imparting energy to the dough by said mixing step in a quantity in excess of 15 watt hours per kilogram of total dough ingredients; controlling the temperature rise in the dough resulting from energy input during said mixing step, by passing a fluid coolant through a jacket surrounding the mixing chamber so that the temperature of the dough after mixing is within the range of 25° C. to 35° C.; adding at least one of the ingredients sugar and fat part way through the mixing process but after at least 25% of the total mixing time in the mixing chamber; and carrying out at least part of the mixing under vacuum conditions.
Claim 5
Independent Claim 26 words
A method of dough mixing according to claims 1 or 2 wherein both said sugar and fat ingredients are added part way through the mixing process.
Claim 6
Independent Claim 37 words
A method of dough mixing according to claims 1 or 2 wherein said coolant is a liquid having a freezing point lower than that of water and said coolant is at a temperature less than 0° C.
Claim 7
Dependent Claim 19 words
A method of dough mixing according to claim 4 wherein said coolant is ethylene glycol or halogenated hydrocarbon (FREON).
Claim 8
Independent Claim 24 words
A method of dough mixing according to claims 1 or 2 wherein at least some of the dry ingredients are pre-cooled before development commences.
Claim 9
Independent Claim 27 words
A method of dough mixing according to claims 1 or 2, in which substantially the entire mixing in the mixing chamber is carried out under vacuum conditions.
Claim 10
Independent Claim 27 words
A method of dough mixing according to claims 1 or 2, wherein the pressure in the mixing chamber is within the range 500 TORR to 250 TORR.
