A method and apparatus for producing a sheet of dough, wherein powdered materials, including flour, yeast, sugar, and fats and oils, for making bread, are mixed with particles of ice, such that the particles of ice do not melt, to make them into a dough mixture. The dough mixture is formed into a continuous belt-like dough mixture having a uniform width and thickness such that the particles of ice do not melt, and then the particles of ice are melted to make the belt-like dough mixture hydrated. Finally continuous hydrated belt-like dough mixture is stretched so that a continuous sheet of dough having a gluten network is provided.

Method and apparatus for producing a sheet of dough

A method is provided for producing bread of a good quality from frozen dough. In this method dough is stretched while being subjected to vibrations so that the dough can be stretched without imparting pressure exceeding the yield point of its elasticity. Thus during the stretching step the gluten network of the dough is unharmed. Further, the dough is rested at least five minutes within a temperature range of 0.degree. C. to 16.degree. C., before it is stretched. Such a dough rested at such a cool condition can be readily stretched, and the stability of the stretched dough is improved over the prior art.

Method for producing bread from preserved dough

A method is provided for producing bread of a good quality from dough preserved in a frozen state. In this method the dough is stretched while subjecting it to vibrations so that the dough can be stretched without imparting pressure exceeding the yield point of its elasticity. Thus the gluten network structure is unharmed. Then the dough is frozen for preserving. After a desired period of preservation the dough is baked. Since the dough does not become deflated, but expands further during the baking step, puffy and tasty bread results.

A method and apparatus for continuously manufacturing multi-layered dough materials containing at least dough layers comprising the steps of continuously extruding material in a tubular form onto a conveyor belt, stretching the material to a thin strip while being transported, folding and piling up the strip of material and re-stretching the piled up material. The apparatus comprises a dough feeder comprising a vertical hollow screw and a double-layered annular bottom outlet, a first conveyor means, a first roller assembly consisting of rollers progressing along a closed orbit, a swinging means positioned between the first and the second roller assemblies for swinging dough material so as to allow it to be piled up on a second conveyor means in a multi-layered form, and a second roller assembly similar to the first roller assembly for stretching the piled up dough material in coaction with the second conveyor means.
