The process comprises preparing a dough roll of batch bread (5) by kneading, shaping and fermenting it in a mold, baking the dough roll in the mold, cooling the baked batch bread, and removing the crust of bread on its sides. The crust of bread is removed by scraping the peripheral surface of the bread using a rotating cutting unit (20). Before and during the removal of the crust, the batch bread is frozen at a surface temperature of 10-30[deg] C to preserve a firm crust for its elimination. The freezing of the bread is carried out by cryogenics or by the producing mechanical cooling. The process comprises preparing a dough roll of batch bread (5) by kneading, shaping and fermenting it in a mold, baking the dough roll in the mold, cooling the baked batch bread, and removing the crust of bread on its sides. The crust of bread is removed by scraping the peripheral surface of the bread using a rotating cutting unit (20). Before and during the removal of the crust, the batch bread is frozen at a surface temperature of 10-30[deg] C to preserve a firm crust for its elimination. The freezing of the bread is carried out by cryogenics or by producing mechanical cooling such as ventilation. During the removal of the crust, the bread is moved in a direction of tangential (T) displacement to the rotary cutting unit or along the direction perpendicular to the axis of rotation (X) of the rotary cutting unit towards the rotation movement of the cutting tools (26). The bread is moved on rollers for forming a moving support by pinching between two mobile strips, by a lug chain, or by a pusher arm having alternating movement. The bread is alternately moved at several times before the rotary cutting unit to remove the crust on its entire periphery, and then simultaneously or successively to the rotary cutting units arranged around the bread to remove the entire crust on its sides. During the removal of the crust, the pieces of the bread crust are aspirated closer to the rotary cutting unit. The pieces of the torn bread crust are evacuated by a simple conveyor belt system, bucket conveyor or rope and button conveyor. After the removal of the crust, the stubs are removed and then the bread is sliced and packaged. The crust is removed to create the final form of the bread in a longitudinal shape with straight, curved, symmetric or non-symmetric, and polygonal or curved such as square, rectangular, triangular, round, oval, heart or star. |
