Problems solved by technology

The quality of sucrose produced by carbonic acid method is better than that of sulfurous acid method, but the production cost is high, and the pollution problem caused by carbonic acid filter sludge is difficult to solve, which makes it difficult to promote the carbon method process
The quality of sucrose produced by sulphite method is worse than that of carbonic acid method, the main problem is color value and SO 2 The residual amount is relatively high. Since 2006, my country has stipulated that the color value of the first-grade white sugar is less than 150IU, SO 2 The content

Embodiment 1

[0023] A sugarcane sugar production process mainly comprises the following steps:

[0024] (1) Squeeze: first press horizontally, the sugarcane enters the press at an angle of 30°, and then presses vertically, the sugarcane enters the press at an angle of 90°, and the sugarcane juice is squeezed out; in this way, the sugarcane enters the press without crushing the sugarcane, Reduce workload and increase sugar yield;

[0025] (2) Filtration: the sugarcane mixed juice is transported in the filter, the filter is equipped with a filter screen, the filter screen aperture is 200-1000nm, the sugarcane juice obtained by pressing is obtained through the filter screen to obtain pure sugarcane juice, and the bagasse is separated to let it Without blocking the filter screen, the insoluble impurities in the sugarcane juice are removed, which is convenient for filtration; the separated bagasse is pressed again to increase the yield of sugarcane juice;

[0026] (3) Clarification and decolor...

Embodiment 2

[0032] A sugarcane sugar production process mainly comprises the following steps:

[0033] (1) Squeeze: first press horizontally, the sugarcane enters the press at an angle of 10°, and then presses vertically, the sugarcane enters the press at an angle of 105°, and the sugarcane juice is squeezed out; in this way, the sugarcane enters the press without crushing the sugarcane, Reduce workload and increase sugar yield;

[0034] (2) Filtration: the sugarcane mixed juice is transported in the filter, the filter is equipped with a filter screen, the filter screen aperture is 200-1000nm, the sugarcane juice obtained by pressing is obtained through the filter screen to obtain pure sugarcane juice, and the bagasse is separated to let it Without blocking the filter screen, the insoluble impurities in the sugarcane juice are removed, which is convenient for filtration; the separated bagasse is pressed again to increase the yield of sugarcane juice;

Abstract

The invention discloses a process for preparing sugar from cane. The process comprises the following steps: pressing, namely horizontally pressing at first and then longitudinally pressing to obtain cane juice; filtering, namely putting the cane juice into a filter to obtain pure cane juice, and separating out cane residues; clarifying and decolorizing, namely heating the pure cane juice, adding citric acid and calcium hydroxide for mixing, adding lime milk for neutralizing, carrying out secondary heating, and adding polyacrylamide for settling separation to obtain clear juice and mud juice; filtering the mud juice to obtain filtered clear juice, combining the clear juice, and adding active carbon into the clear juice for deodorizing; performing evaporation concentration, sugar boiling and crystallization, honey separation and drying to obtain the finished sugar. The process has good filtering, clarifying and deodorizing effects, and is time-saving, labor-saving and simple to operate.

Description

technical field [0001] The invention relates to the field of sugar production, in particular to a sugar cane sugar production process. Background technique [0002] Sugarcane is the main raw material for sugar production in my country. In the world's total sugar production, sugarcane accounts for about 65%, while my country accounts for more than 80%. Sugar is one of the essential foodstuffs for human beings, and it is also an important raw material for food industries such as candy and beverages. It is also an important raw material for light industry, chemical industry and energy. The development of sugarcane production plays an important role in improving people's lives, promoting the development of agriculture and related industries, and even the development of the entire national economy. [0003] Sugarcane is a grass plant that grows in the tropics and subtropics. my country is one of the earliest countries in the world to make sugar from sugarcane. It has a history...
