Clarifying method for redissolving brown granulated sugar with primary wash syrup

Abstract

The invention discloses a clarifying method for redissolving brown granulated sugar with primary wash syrup. The clarifying method comprises the following steps that brown granulated sugar is dissolved, and a brown granulated sugar solution is obtained; the brown granulated sugar solution and primary wash syrup are mixed, mixed syrup is obtained, and preheating is carried out; the mixed syrup enters a stirring box, and phosphoric acid and saccharified calcium are added; the mixture enters a foaming box, and crude syrup is foamed into uniform foam; the foamed mixed syrup is led into a floating device from a juice outlet pipe, a decolorizing agent attapulgite and flocculating agents zinc dihydrogen phosphate and guar gum are added before the mixed syrup is led into the floating device, floating separation is carried out on the mixed syrup in the floating device, upper layer floating residues are scraped away by the floating device, and cleaned syrup is discharged from the bottom; the mixed syrup enters a settling device, and chitosan is added to carry out secondary decolorizing, wherein the stirring time is 1 min, and the reaction time is 15-20 min. According to the method, mixed treatment is carried out on two materials with high tone, the re-boiling amount of low-purity materials is increased, and thus the yield of white granulated sugar is increased.

Description

technical field [0001] The invention relates to the field of sugar production, in particular to a clarification method for back-dissolving brown granulated sugar with caramelized honey. Background technique [0002] At present, the one-step process is generally adopted in sugar cane sugar production in my country, and the final crystallization product is brown granulated sugar; the brown granulated sugar has many impurities and high color value, which no longer meets the market demand; Re-dissolution and re-cooking or interplanting; at the same time, due to the high non-sugar content and color value of red granulated sugar, direct re-dissolution and re-cooking or inter-planting of red granulated sugar will also affect the quality of white granulated sugar, making the color value high or even exceed the standard; and the red granulated sugar in The pigments are mainly sugar decomposition products and polymer colored substances produced during the cooking process (brownish black...

[0002] At present, the one-step process is generally adopted in sugarcane sugar production in my country, and the final crystallization product is brown granulated sugar; the brown granulated sugar has many impurities and high color value, which no longer meets the market demand; Re-dissolution and re-cooking or interplanting; at the same time, due to the high non-sugar content and color value of red granulated sugar, direct re-dissolution and re-cooking or inter-planting of red granulated sugar will also affect the quality of white granulated sugar, making the color value high or even exceed the standard; and the red granulated sugar in The pigments are mainly sugar decomposition products and polymer colored substances produced during the cooking process (brownish black to brownish yellow, mostly caramel pigments and melaninoid pigments), and their crystal transfer rate is very high, which affects the color value of the finished sugar much larger pigment than cane juice itself
