Sugar Mill
• A cane sugar mill is a factory that processes sugar cane to produce raw or white sugar.
Sugar Cane
Sugarcane refers to any of 6 to 37 species (depending on which taxonomic system is used) of tall perennial grasses of the genus Saccharum (family Poaceae, tribe Andropogoneae).
Native to warm temperate to tropical regions of Asia, they have stout, jointed, fibrous stalks that are rich in sugar, and measure two to six meters (six to nineteen feet) tall. All sugar cane species interbreed, and the major commercial cultivars are complex hybrids.
Sugar cane products include table sugar, falernum, molasses, rum, cachaça (the national spirit of Brazil), bagasse and ethanol.
Raw Sugar Manufacturing Process
Extraction
Cane Handling
The cane will be dumped in the feeding carrier. The feeding carrier will carry the canes and transfer it to the cane carrier. In the feeding carrier there is an equalizer and kicker which are responsible for efficient feeding in the cane carrier. Then the canes will pass through a leveller, two cutters, another leveller and then a kicker. Then it will be shredded in the shredder.The shredded cane will be carried by the shredded cane elevator. It will be received by the two pusher rollers. Then, the canes will be pushed to the three rollers where the juice will be extracted. The bagasse will be carried by the intermediate carrier and then to the next mill. There are five mills in the station. There is a maceration box in the 2nd mill. The mixed juice extracted in 5th mill will be pumped to the 4th mill; the mixed juice in the 4th mill will be pumped to the 3rd mill; the one in the 3rd mill will pumped to the 2nd mill. There is no maceration in the 1st mill. The pure juice in the 1st mill will be mixed with the extracted juice in the 2nd mill and will be pumped to the rotary juice filter.
Auxiliary Parts of the Cane Handling Station
DUMPER
The dumper will aid the trucks without built in dumpers in dumping their sugar canes on the feeding carrier.
FEEDING CARRIER
It transports the dumped cane to the equalizer, kicker and into the cane carrier. It is powered by a motor. Its speed is manually controlled by the operator.
EQUALIZER
It controls the level of the canes and it will make sure that the canes are evenly distributed. The rotation of the equalizer is against the direction of the feeding carrier. This is driven by a motor.
FEEDING CARRIER KICKER
It pushes the canes from the feeding carrier to the cane carrier. Its rotation is along with the direction of the feeding carrier. This is driven by a motor.
CANE CARRIER
It carries and transports the cane coming from the feeding carrier into the shredder.
CANE CUTTER
It cuts the cane in the cane carrier. This is powered by a motor.
CANE SHREDDER
Its function is to pulverize the canes. It is composed of 88 swing type hammers properly arranged into 8 rows. Each row has 11 hammers. It is responsible in pulverizing the cane. Because of too high rpm, it can produce shredded canes. It is driven by a 800 KW turbine.
