Similar to other processes, bread production is composed of multiple steps, twelve to be exact. The processes that fall under bread production are as follows: sponge mixing, fermentation, dough mixing, make-up line, final proofing, oven baking, depanning, cooling, tumbling, slicing, packaging, and dispatch.
First, the ingredients are prepared and stored into huge silos prior to their release to the sponge and dough mixers. In sponge mixing, half of the ingredients are mixed in giant horizontal sponge mixers. Then, the sponge is fermented for several hours in a cold room, enhancing the bread’s aroma, texture and flavor. Once fermentation is done, the sponge heads to the dough mixer wherein the rest of the ingredients are mixed to form the dough.
The next station of the Gardenia bread making process is the make-up line, which is composed of four controlled operations: diving, rounding, intermediate proofing, and molding. In the dividing section, the dough is cut into the required size and weight of the loaf; and since all processes are automated, the pieces are ensured to be accurately scaled and consistent. Then, the dough enters the rounder and passes through the check weigher. The intermediate proofer allows the dough to rest so it can go to the molding rollers without tearing. In molding, the dough pieces are flatted, rolled into cylindrical shape, sealed, and cut into their final form. They are twisted and placed into baking pans. The final proofing involves moving the dough pieces into a large proof box for temperature and humidity control.
Baking is done in a 30-meter long tunnel oven with an indirect fire system, heated by environmentally friendly liquefied petroleum gas. Using air burst, the bread is loosened from the pan; the gentle suctions automatically lift the bread out of the pan and move the bread into a conveyor heading towards the spiral coolers. Each loaf passes through the tumbling station where all sides are checked by highly trained visual inspectors. After tumbling, the breads are now sliced into equal slices and put into bags, sealed with color coded G-locks with printed batch and traceability number, price, and expiration date. After packaging, the loaves pass through a metal detector to ensure that there are no metal contaminants in the bread. Once the loaves are clear, they are now ready for dispatch.
