Manufactured for professional bakers, the 1428 Lower fire box Oven with a throat is the smallest oven designed for a loading with a conveyor in the Lower fire box Oven range. This bakery oven can bake up to 50 baguettes or 32 loaves of 500 g bread per batch.

With its lower throat heating system, the inferior fire set below the baking room and communicates directly with the baking room through the throat, which can be oriented to direct the flame to the different areas of the baking room.

Once the desired temperature has been reached, the throat is removed and the slot is closed up. This ensures optimum heat distribution throughout the oven.
