The production of rolls starts with dough production and dough make-up. Next, the dough pieces are given their final proof before they reach the Therm hermhermadordordor tunnel oven. Alternatively, the process can also be used with multi-level technology. Industrially produced rolls can be either baked directly on the hearth or on trays. The number of oven modules is depending on the necessary baking time in relation to the maximum traveling speed (performance). Via cooling conveyors, the baked products are moved to the packaging equipment.
