<p>The present invention provides an apparatus for preparing dough of good quality for bread without destroying the gluten network structure or producing friction heat, comprising a mortar (M) adapted to receive a material (B) for dough including wheat flour, yeast, table salt and other necessary ingredients and water and driven for rotation in its entirety or partly at its lower portion alone by a mortar driving motor (93) housed in an installation machine frame (F), a resistance vane (W) opposed to the interior of the mortar (M) for overturning the dough, a pestle lifting shaft (33) driven by a separate pestle driving motor (11) housed in the installation machine frame (F) to be moved through crank motion by a given stroke (S) toward the mortar (M), and a pestle (P) freely rotatably fitted on the lower end portion of the pestle lifting shaft (33) through bearings (58, 59) for pounding the dough received in the mortar (M), the arrangement being such that when the pestle (P) is lowered, it is rotated concomitantly with the dough nipped in a vertical relative spacing (C) defined between the pestle (P) and the mortar (M).</p> |
