The key to the automated production line of Beiguo is actually the flexible conveyor belt, which is good for shaping dough. The entire shaped conveyor belt is also circular, and when the dough is made into a ring, it will be restored to a flat conveyor belt at the bottom. The tunnel through which the dough rolls into a curved strip relies on the frictional force of the flexible conveyor belt to continue rolling the entire dough. Once it exits the tunnel, it is already twisted into a ring and connected from end to end. Afterwards, there is a big difference in making doughnuts with bagels. Doughnuts are made by fermenting the dough and sending it for frying, while bagels are made by boiling the dough in hot water and sending it for roasting. Friends who enjoy collecting souls, I have to say that this machine is n times more efficient than pure hand pinching! But I haven't found an automatic production line for bagels that can be filled yet. Perhaps this is another unique change in hand bag bagels besides having a soul?
