Company Introduction
Coming from intermediate proofing, rounded dough pieces are sheeted or gradually flattened through a series of rollers in preparation for final moulding. The sheeter is usually comprised of 2–3 sets (in series) of Teflon-coated roller heads between which the dough piece is passed to gradually flatten the dough piece.
Sheeting applies stress forces (pressure) that help degas the dough piece so that large air cells developed during product transfer or intermediate proofing are reduced into smaller ones to achieve a fine grain in the finished product.
Roller sets are arranged in such a way that the gap/clearance is reduced gradually as the dough travels through them. This is critical to promote a controlled reduction of dough thickness. It would be impossible to flatten dough pieces in one single step without causing irreparable damage to the gluten and gas cell structure.
After passing through the top rollers, the dough piece becomes much thinner, larger, and oblong in shape. The flattened dough exiting the bottom rollers is ready to pass under the curling chain.
