Okay kiddo, wet processing engineering is all about making things in a factory that use water. A lot of things we use and eat are made using wet processing. In fact, you know how we wash our clothes at home? Wet processing is kind of like that, but on a super-big scale.
So, let's say we want to make orange juice. First, we have to wash the oranges to make sure they are clean. Then, we use a special machine to crush the oranges to make juice. This machine adds water to help get all the juice out of the oranges. The juice and water mixture is then separated from the leftover pulp and skins.
But the process doesn't stop there! The juice and water mixture has to be cleaned to remove any dirt, seeds or leftover pulp. This is done using filters and machines that spin the juice really fast, like a merry-go-round, to separate the heavy dirt and seeds from the lighter juice.
Once the juice is clean, we can add sugar or other fruits to make a sweet and tasty orange juice. Finally, the juice is bottled and sent off to supermarkets where people like you and me can buy it!
So, that's wet processing engineering in a nutshell. It's all about using water to make things like juices, milk, chocolate, and many other foods and products that we use every day.
