First, the harvesting of raw materials is very important. Sugar cane needs to be picked in the summer when it is ripe, while beet needs to be picked in the fall. After picking, it needs to be processed immediately to avoid spoilage and loss of raw materials.
Secondly, the raw material needs to be liquefied. During this process, the raw material is crushed into small pieces and is extracted by the flow of water. This step is very important as it helps remove impurities from the raw material and prepares it for the subsequent process.
Next, the liquefied feedstock is filtered to remove impurities and rod and culm fragments from it. This process requires the filter to be flushed through the feedstock using high temperature and high pressure water to ensure the purity of what is in it. Once the filtration is complete, the remaining liquid is separated and used for subsequent boiling.
Boiling is a critical step in the manufacture of brown sugar. During this process, the liquid ingredients need to be heated continuously until the water evaporates and the sugar is concentrated to a certain level. This process requires patience and care, as boiling for too long or at too high a temperature can cause the sugar to burn and spoil.
Finally, the boiled syrup is poured into molds and left to dry at room temperature. The drying time depends on the thickness and temperature of the syrup in the molds and usually takes days or even weeks. During the drying process, the brown sugar will gradually become hard and give off a special aroma and flavor.
In short, the process of making brown sugar involves a number of steps, each of which requires specialized skills and experience. The finished brown sugar not only has a rich flavor and aroma, but is also rich in a variety of nutrients that are beneficial to the human body, making it one of the indispensable sources of sweetness in people's diets.
