Model Answer 1 (Band 9)

The process of sugar production from the sugar cane plant entails a three-pronged approach that comprises natural growth, followed by a chemical transformation, culminating in the separation of the sugar crystals from the end product. Taking a comprehensive view, it is evident that this multifaceted process entails harvesting, processing, and purification.


The first phase is a natural occurrence that commences with the sugar cane plant's growth, spanning a 12-18 month cycle. Once the cane has reached maturity, it is harvested using either hand tools or robust agricultural machinery. Following the harvesting process, the stalks undergo crushing via a grinder, resulting in the extraction of raw sugar cane juice.


Subsequently, the extracted juice is directed through a limestone filter and then poured into an evaporator, where it undergoes heating, reduction, and thickening, eventually resulting in a thick, viscous syrup. Thereafter, the syrup undergoes separation from the sugar crystals using a centrifuge, which serves to isolate the sugar crystals from the syrup. Lastly, the sugar is dried and cooled, resulting in the refined granulated sugar as the final product.

Model Answer 2 (Band 9)

The presented process diagram provides a comprehensive overview of the intricate stages involved in the production of sugar from sugar cane. The process comprises seven sequential stages, incorporating only two variations.


The process commences with the cultivation of sugar cane, which requires a growth period of twelve to eighteen months. Upon maturity, the crop is then harvested, either by means of a tractor or through manual collection.


The harvested sugar cane then undergoes crushing to extract the juice, which is subsequently purified through a limestone filter. The purified juice is then heated in an evaporator, where it goes through a transformation into a syrup-like substance. Next, the syrup is processed through a centrifuge, leading to the separation of sugar crystals from the syrup.


In the final stage, the extracted sugar is subjected to cooling and drying in a vat of some sort, culminating in the production of plain sugar. This process highlights the intricate nature of sugar production, requiring precise attention to detail and a series of systematic steps.

Model Answer 3 (Band 8)

The provided illustration elucidates the intricate stages involved in the production of sugar from sugar cane. The process involves a series of systematic steps, encompassing harvesting, crushing, syrup-making, centrifuging, and ultimately, drying and cooling.


As illustrated in the diagram, the sugar cane plants are ready for processing when they are over one year old, and the manufacturing process commences with their harvesting, which can be done either manually or through the use of machines.

In the next step, the harvested sugar canes undergo crushing in a crusher machine, producing juice, which is then purified by a limestone filter. The purified juice is then heated in an evaporator, transforming it into a syrup-like substance. Subsequently, the syrup undergoes centrifuging, causing the separation of sugar crystals from the syrup.


The final step in the production of sugar involves the drying and cooling of the extracted sugar crystals, resulting in the production of sugar that is safe for consumption. This process requires precision and a keen attention to detail to ensure high-quality sugar products.

Model Answer 4 (Band 7.5)

The given illustration depicts the various stages involved in the production of sugar from sugar cane.


Overall, the entire process consists of seven main phases, which begin with the cultivation of sugar cane on farms and culminate in the production of refined sugar that is ready for consumption.


As per the process diagram, the first stage involves harvesting the sugar cane plants from the fields once they have matured, which takes approximately a year to eighteen months. Harvesting is accomplished either through manual labour or with the aid of agricultural machinery. Following this, the sugar cane is crushed in a grinder to extract the juice, which is then purified using a limestone filter. The juice is then heated in an evaporator to create a syrup, which is subsequently poured into a centrifuge machine to separate the sugar crystals from the syrup. The final stage involves drying and cooling the sugar crystals to produce the final product - sugar.



Model Answer 5 (Band 7)

The processes involved in making sugar from sugar cane plants are shown in the graphic diagram.


In general, there are seven primary steps in the manufacturing of sugar, which begin with the cultivation of sugar cane on farms and end with the drying and chilling of crystal syrup to create sugar that is suitable for consumption.


The first phase involves harvesting the sugar cane plants from the farms when they are between a year and eighteen months old, as the process graphic depicts. Sugar cane plants can be harvested manually or with the use of agricultural equipment. After that, sugar cane juice is created by crushing the sugar cane stalks in a grinder. After that, a limestone filter is used to clean this juice. The juice is then heated in an evaporator machine. The syrup is produced during this process by the vaporization of water and is then placed through a centrifuge to separate the sugar crystals from the syrup. The produced crystals are then dried and chilled to produce the finished product, which is sugar.
