How to Make White Sugar

The age of licentiousness is over
Selected answers

1. Pretreatment of sugarcane before crushing

Sugarcane pretreatment mainly uses crushing equipment to cut and tear the sugarcane, so that the sugarcane can be fully broken. The compressor harvests a lot of sand, mud, stones and other sundries in the sugarcane, which can be broken only after washing and sand discharging.

2. Press

After sugarcane enters the compressor unit, sugar is extracted through multiple pressing and multiple infiltration, which is the main part of the whole compression section. After the sugarcane is pressed, the juice and bagasse shall be transported separately to ensure the normal pressing. The mixed juice contains a lot of sugarcane chips, which should be separated by the curved plug, and the recovered sugarcane chips should be sent back to the cane press for processing.

3. Cleaning of sugarcane juice

The mixed juice sent from the juice extraction section is dark green turbid liquid, and its main component is sucrose, in addition, it also contains insoluble non sugar impurities. Such as chlorophyll, sugarcane chips, soil and other suspended substances, as well as soluble non sugar impurities, such as various organic salts, colloidal substances and inorganic salts. The cleaning method is generally to heat the mixed juice and add chemicals to precipitate impurities, and then separate the precipitates to obtain clear and transparent juice with low chroma. In order to obtain the maximum effect of removing non sugar, the sediment should also have good sedimentation performance and filtration performance to facilitate separation.

4. Evaporation of sugarcane juice

In order to reduce the consumption of steam, the utilization of secondary steam is a main way, so it has become the center of thermal economy research in sugar mills. The potential of the secondary steam evaporated from sugarcane juice, which can not only be used for the next heating, but also be drawn out for other equipment, and can also be extracted as the heating steam of the first effect evaporation tank after the pressure is increased through compression. The secondary steam extracted from the evaporation tank and used for other equipment is usually extracted from the pipe of the secondary steam, but also from the steam drum of the next effect, which can improve the flow rate of steam in the steam drum and fully eliminate non condensable gas, thus improving the evaporation energy release of the next release.

5. Crystallization of sucrose

The clear juice is evaporated and concentrated into a syrup with 60-65b force and a temperature of about 60 ℃, which is called coarse syrup. It must be further concentrated to precipitate and crystallize. Boiled crystals. The mixture with molasses is called molasses. After the sugar paste is unloaded, it is cooled down to make the precipitation of sucrose more complete, and the original and crystal continue to grow. This process is called crystallization aid. The sugar paste after crystallization is separated from sugar and molasses by high-speed rotary centrifuge. The white granulated sugar obtained from the separation is dried and screened to obtain a product of certain specifications, which is the finished white granulated sugar.

What kind of system did the Yuan Dynasty use to manage China

The Yuan Dynasty (1271-1368) was the first unified dynasty established by ethnic minorities in Chinese history. The ruler was the Mongolian Bor Jijin. It is said that the Fifth and Eleventh Emperors lasted for 162 years since Genghis Khan established the Mongolian regime in 1206 and 98 years since Kublai Khan designated the country as Yuan. After the Yuan Dynasty withdrew from the Central Plains, the Northern Yuan regime lasted until 1402.
In 1206, Genghis Khan unified all Mongolian ministries and established the Great Mongolia. They successively attacked and destroyed the regimes of Xiliao, Xixia, Khwarazimu, Jin Dynasty, etc. After the death of Mengge Khan, the dispute between Ali Buge and Kublai Khan over the position of Khan triggered the split of the Great Mongolia. In 1260, Kublai Khan ascended the throne and became emperor. He established "Zhongtong" in the Yuan Dynasty and the capital was Kaiping Mansion (Xanadu). In 1271, Kublai Khan changed the name of the country to "Dayuan" after taking the meaning of "Dazai Qianyuan" in the Book of Changes, and the capital was set in Dadu the next year. In 1279, the long-term chaos since the end of the Tang Dynasty ended. After that, the Yuan Dynasty continued to expand outward, attacking Japan, Myanmar, Vietnam, Java, etc., but all failed. In the middle of the Yuan Dynasty, the succession to the throne was disordered, the politics had never been on the right track, and the sinicization was slow and development was slow. In the later period, political corruption, political interference by powerful officials, and increasing ethnic and class contradictions led to the peasant uprising at the end of the Yuan Dynasty. In 1368, Zhu Yuanzhang established the Ming Dynasty, and then the Northern Expedition drove the Yuan Dynasty to occupy Dadu. Since then, the Yuan court retired to Mobei, known as the Northern Yuan Dynasty. In 1402, Yuan minister Guilichi usurped the power to establish Tatars, and the Northern Yuan Dynasty perished.
During the Yuan Dynasty, the unified multi-ethnic country was further consolidated and its territory exceeded that of previous dynasties. The Yuan Dynasty abolished the Shangshu Province and its subordinate provinces, and retained the three powers of the Zhongshu Province, the Privy Council and the Imperial Historian's Office, which were respectively in charge of politics, military affairs and supervision. The provincial system was implemented locally, which was the first of its kind in China.

What is the largest planet in the universe?

The largest planet in the universe is the red giant star. The super star is 114 times larger than the sun in diameter and is part of a binary system. The mass of this star is 150 times that of the sun. Experts support that this is the first time in human history that such a huge star system has been observed. The mass of the largest star previously discovered is 83 times that of the sun.
Shield UY is located in the distant shield, with a radius 2000 times larger than the sun and a volume of about 5 billion times the sun. But the quality is only 12 times. It is estimated that the mass of this star is only about 10 times that of the sun. During its evolution to a red supergiant, it expanded rapidly and lost at least half of its mass.
The stars in the solar system are 58 times larger than the earth, and Uranus is 65 times larger than the earth. So the earth is not too bad, not too small. Then compared with larger planets, for example, Saturn is 830 times the size of the Earth, Jupiter is 1300 times the size of the Earth, and the size difference of thousands of times can already feel the insignificance of the Earth. The earth may not even count as a grain of dust in the universe. But even the earth, which is not even a speck of dust in the universe, has bred countless intelligent lives, especially the highly intelligent creatures like human beings, which are unmatched by many large planets.
