DOUGH-SKIN FOLDING DEVICE

摘要

The dough-skin folding device contains two or more folding assemblies above a conveyor belt. Each folding assembly contains a base plate and a transmission member beneath the base plate. The transmission member contains pairs of shafts arranged in two rows. Each shaft has a bottom end engaged by a rotatable roller. A pair of the rollers, driven by a power source, makes the other rollers to spin synchronously through transmission belts. A spatula is positioned in front of each folding assembly, and contains a curved blade aligned to the gap between the two rows of rollers. When a dough-skin is moved towards the folding assembles, the dough-skin's lateral sides are scraped up by spatulas and they are folded towards the middle by rollers into a loaf of dough having three layers of dough-skin for subsequent processes. The loaf of dough has multi-level mouthfeel similar to one manually made.

主权项

1. A dough-skin folding device, comprising two or more folding assemblies on top of a conveyor belt, each folding assembly comprising:
a base plate positioned above the conveyor belt by a support element; a transmission member beneath the base plate comprising a plural pairs of shafts arranged in two rows where each shaft has a top end threaded through and fixed to the base plate by a fastening element, and a bottom end engaged by a rotatable roller through at least a bearing set, and the rollers in the same row are surrounded by a transmission belt so that these rollers spin synchronously, a pair of the rollers at one end of the two rows is the driving pair which make the other rollers on the same rows to spin synchronously through the transmission belts, and a gap is reserved between the two rows for a dough-skin to be pressed and kneaded; a power source raised on top to an end of the base plate where an axle of the power source engages a first roller in the driving pair through a corresponding first shaft, the first shaft is threaded through a first gear whereas a second roller in the driving pair is threaded through a second gear engaged by the first gear; and a spatula positioned in front of an end of the folding assembly comprising a curved blade and a support element where the curved blade is positioned so that it is aligned to a gap between the two rows of rollers, and each spatula and corresponding folding assembly are positioned at an angle to the moving direction of the dough-skin on the conveyor belt.
