Unit 13A, production, listening one. So, this is a diagram of the bakery. Now it all begins with the main ingredients. Those are flour and water. They're weighed and fed automatically into mixes. Yeast and additives are then added by hand. And everything is mixed together for 12 minutes to make the dough. Well, what are the additives for? Oh, they're just to increase the shelf life of the baguettes. The dough was then divided into pieces. And after the weight is checked, the dough enters the first proofer for 10 minutes. It's the first what? Prover. What's a proofer? I can tell you haven't baked bread before. No, that's very true. Well, you can't bake the dough straight away. You have to let it stand for a while so the yeast can react before you form it. This is called proving, right? Well, now the yeast makes the dough rise and gives the bread shape and volume.

All right, I see. So the dough is then formed into a baguette and dropped onto trays, which then continuously go around a circuit. The trays take the baguettes into another proofer for 60 minutes. The temperature in the proofer is perfect for the yeast to make the bread rise even more. 60 minutes, that long. The proofer stage is very important. If the bread doesn't prove properly, you can't bake it. Now the trays then continue around the circuit of the oven where the bread is baked for 10 minutes. And after leaving the oven, the trays enter the cooler. That's where cool air is blown over them for 40 minutes. The baguettes are then taken off the trays and dropped into plastic baskets for packaging. And the trays continue around the circuit and go back to the start again. And what happens to the baguettes? Oh, they're taken to the packing hall where they're wrapped boxed in this batch. And how long does the whole process take? From flour to boxed products takes about 2.5 hours.

Unit 13A. Production. Listening to. So, Brian, what problems do you have with the production line? Well, we have a lot of problems with sensors. These are electronic sensors that tell the computer. When a tray enters or leaves a prover or oven. The computer monitors the circuit and controls the speed of the trays. The computer stops the whole process when a sensor stops working properly. A complete shutdown. Really? Well, you have to remember that the line produces 6,000 baguettes an hour. The timing has to be perfect or the system stops. The sensors have to be set up exactly right. If they aren't, the computer won't start the system.

What other problems do you have? Well, sometimes we have problems with the mixes. If the computer gets the mix wrong, we have to clean out the whole mixer. Do you have any problems with your workers? Not often, no. The system produces a new mix every 12 minutes, so it is possible that a mixer man can forget to put in the yeast in additives. If he forgets the extra ingredients, we lose the whole mix.

Any other kinds of problems? Occasionally, we have mechanical problems. Like when an old tray loses its shape, it can jam in a prover or oven. That can be a big problem, because it can damage the machine and jam the whole system. So, how much time do you lose a day on average? Oh, that's difficult to say, really. On a good day, maybe six minutes? We can lose up to an hour and a half of production if we have a really bad day. And that means nearly 10,000 begets.
