_P1 The World of Coca-Cola Museum in Atlanta has a special room showing the Coca-Cola bottling process. The process is complex and interesting. It takes many steps to make bottles of Coke taste the same. The special room is full of clamps (robotic arms), machines and so on. The exhibit is like a real bottling factory. The process is just slowed down for guests to see what goes on. Almost everything is operated by machines.
P2 First of all, the Cokes are taken to the cleaning unit. Here, the bottles are cleaned. This is done by jet streams and water. Then, they are picked up by an overhead conveyer belt.สายพานลำเลียง Individual clamps pick up a bottle, and they are transported from station to station.
P3 Coke is bottled using four different steps. First, pure water is put in the bottle by a machine, after that, refined sugar is added to the mix. (29) __________, the sugar water gets some caramel coloring. A machine shakes the bottles up a bit to make sure everything is mixed together well. After everything is mixed, carbon dioxide is added to the mix to make the drink fizz. Finally, the machines then send the bottle down another conveyer belt. This would be the point where drinks would be checked by a person for quality. However, visitors are not allowed to see this final step.
P4 The exhibit continues to the back of the museum, where visitors exit. The eight-ounce glass bottles of Cokes come off the conveyer belt, and they are available for visitors to take home.
