Topic: The diagram below shows the manufacturing process for making sugar from sugar cane.

Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The flow chart depicts the sugar manufacturing process, from sugar canes as the raw material to sugar as the finished product.

Overall, the production consists of seven different steps, the first two of which are about sugar cane cultivation and harvesting, and the rest of which are about the processing of harvested canes. Relevant equipment includes crushers, filters, evaporators and centrifuges.

The first two steps are to plant sugar canes, which take 12 to 18 months to grow, and haverst matured ones manually and mechanically. The next five steps are to extract sugar crystals from reaped crops. Their stalls are put into the crusher to produce sugar cane juice, which is channeled through the limestone filter for purification before being boiled in the evaporator to remove excess water. The resulting syrup is added to the centrifuge to separate sugar crystals, which dry and cool in a large vessle and finally become sugar.
