Abstract: A process for preparing a yeast raised doughnut comprising fermenting a dough, degassing the same, cutting and forming the dough and then frying the same in oil.

Abstract: Disclosed is a machine for forming viscous fluid crude material such as dough or fish-paste into a ring shape or the like. The machine has a cutter device provided with a vertical passage and cutter means arranged at the lower opening of the passage. The crude material is forcely introduced into the passage through its upper opening and extruded from its lower opening. The extruded crude material is cut off by means of the cutter means. Moreover, the passage is partitioned at least in its upper portion into a plurality of sector-shaped sections by means of a separator. Accordingly, the formed crude material can be sectioned into a plurality of portions of different tastes and/or colors.

Abstract: Disclosed is a dough forming device comprising a dough tank, an extrusion member, a cutting member and a separator. The tank has a dough guiding hole with a lower end opening. The extrusion member is moved from the interior of the tank into the guiding hole in order to extrude the dough from the tank through the lower end opening, the extruded dough being expanded radially along the upper surface of the cutting member positioned below the lower end opening. Thereafter, the cutting member is moved to a position in which it is engaged with the lower end opening, so that the expanded dough is cut into an annular body by means of the cutting member. The tank is divided into sector-shaped sections by means of the separator. In case of the sections being filled with doughs of different colors and/or tastes, the expanded and cut body is composed of zones of different colors and/or tastes.
