The diagram illustrates the method of producing carbonated drinks. Overall, it involves 5 stages, ranging from Water cleaning (stage 1) to Packaging (stage 5). It requires specialised equipment to convert raw water into carbonated drinks.
Firstly, water goes through a filteration process in a filter machine. In this stage, water softeners as well as chemicals are added to purify water. The filtered water is then pumped into electric heaters for the second stage, which is called Heating, evaporation and carbonation stage. As the name suggests, there are three sub-steps within this stage. The water is heated and then the hot water from the heaters is pushed into a cooling pipe, which is further attached to a carbon dioxide tank. This tank is responsible for the process of carbonation. In other words, carbon dioxide is added to water at this point. Carbonated water travels through a long pipe to reach the mixing tank.
Stage 3 of the procedure involves mixing. Hence, it is called the Mixing stage.Required amounts of colour, sugar syrup and flavour are added to carbonated water in the mixing tank. For instance, for an orange drink, appropriate orange colour and fruit flavour is mixed in water along with sugar syrup. Next, the carbonated drink is filtered once again and consequently, filled in bottles and cans in the fourth stage which is the Filtering and filling stage. Finally, the carbonated drinks are ready to be packed (Stage 5 – packaging) and sent to the supermarkets for sale.
In summary, this 5 stage long process converts water in flavoured carbonated drinks.
