Embodiment 1

[0048] A kind of sugar making process based on membrane method clarification multiple co-production, comprises the following steps:

[0049] A. Extracting sugarcane juice: using conventional five presses to squeeze sugarcane to obtain a Brix of 13-15 o Mixture of Bx;

[0050] B. Pre-ash: add sucrose calcium to the mixed juice, and adjust the pH value to 6.8-7.2.

[0051] C. Physical impurity removal: The pre-ashed mixed juice is passed through a drum sieve, a heating skimming device, and a microporous filter in sequence for physical impurity removal to obtain filtered clear juice.

[0052] D. Concentration for the first time: Use the MVR concentrator to concentrate the filtered clear juice to obtain a Brix of 18-20 o Bx's juice concentrate and sugarcane raw water.

[0053] E. Ceramic membrane filtration: filter the concentrated juice with a ceramic membrane with a membrane pore size of 20nm to obtain membrane filtrate and membrane filtrate concentrate with turbidity less th...

Abstract

The invention discloses a sugar refining process based on membrane method clarification polybasic co-generation, which comprises the following steps: physically removing impurities from mixed juice, concentrating the mixed juice for the first time to 18-20 oBx, physically clarifying the concentrated mixed juice by a ceramic membrane, concentrating membrane-process clear juice for the second time to obtain syrup of 55-65 oBx, and producing white granulated sugar and low-sucrose liquid sugar according to a conventional white granulated sugar boiling process; filtering the raw sugarcane water obtained in the first concentration process and the second concentration process with activated carbon and a reverse osmosis membrane to prepare sugarcane plant water; and centrifugally clarifying the impurity-containing concentrated liquid filtered by the ceramic membrane, and mixing with molasses to produce the brown sugar. According to the membrane method clarification process based on no addition of chemical additives, by-products are utilized in a high-valued manner, a product chain is prolonged, economic benefits are increased, and the amount of mixed juice for subsequent membrane method clarification is reduced through first concentration, so that the investment of membrane method clarification equipment is reduced, the production cost is reduced, and the economic benefits of sugarcane sugar manufacturing enterprises are greatly improved.

Description

technical field [0001] The invention relates to the technical field of sugar cane sugar production, in particular to a sugar production process based on membrane method clarification and multiple co-production. Background technique [0002] Sugarcane, (scientific name: Saccharum officinarum ) Saccharum, perennial tall solid herb. The rhizome is thick and well developed. Stems 3-6 meters high. Sugarcane is suitable for planting in places with fertile soil, sufficient sunlight, and large temperature differences between winter and summer. Sugar cane is a temperate and tropical crop that is used as a raw material for the manufacture of sugar and for ethanol as an energy substitute. Sugarcane is an important sugar crop in my country and the main source of sugar. Sugar is an important product related to the national economy and people's livelihood. Oil and petroleum are both national strategic materials. Sugarcane is also the economic crop with the largest planting area in Gu...
