Embodiment Construction

[0036] Because the sugar juice decolorizer of the present invention relates to food production safety. Carrying out the method of the present invention requires careful selection of starting materials. Phosphoric acid chooses food grade phosphoric acid. In addition to meeting relevant industrial standards, talcum powder and heavy calcium carbonate powder should also have low content of arsenic, lead, and heavy metals, so that the final product can meet the relevant food-grade requirements, and no new Toxic and harmful substances are in line with the food hygiene and safety of sugar factories.

[0037] A preparation method of compound phosphate sugar juice decolorizer:

[0038] 1. Stone powder reaction

[0039] Weigh a certain amount of food phosphoric acid in a 1-liter glass beaker, gradually add the required talcum powder under heating and stirring, keep the temperature at 95°C to 110°C, continue stirring and reacting for about 40 minutes, keep warm for later use.

Abstract

The invention provides a composite phosphate sugar juice decoloring agent and a preparation method thereof, which belongs to the technical field of chemical engineering. The decoloring agent consists of the following four components: (1) calcium biphosphate, (2) magnesium dihydrogen phosphate, (3) precipitated silica and (4) free phosphoric acid. The preparation method for the decoloring agent comprises the following steps: (1) talc is added to food-grade phosphoric acid hydrolysate and dissolved, so as to obtain a phosphoric acid aqueous solution which dissolves magnesium dihydrogen phosphate and disperses precipitated silica; and (2) heavy calcium carbonate powder is put into a mixer and added with the phosphoric acid aqueous solution in a step (1), and reaction evaporates the moisture of materials and progressively cures the materials, so as to obtain the composite phosphate sugar juice decoloring agent containing moisture. Compared with the food-grade phosphoric acid used by the prior sugar factories, the decoloring agent has the advantages of good decoloring effect, economical efficiency, convenience, no relation to dangerous chemicals, and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a production method and application of a compound sugar juice decolorizing agent, in particular to a compound phosphate decolorizing agent and a preparation method thereof. Background technique [0002] Sugarcane sugar has a history of more than one thousand years. In the modern sugarcane sugar production process, the sugarcane is first shredded, squeezed, and extracted to obtain a sugar-containing mixed juice. After clarification and decolorization, the mixed juice is concentrated, crystallized, separated, and dried to obtain relatively pure white sugar. [0003] The mixed juice contains thousands of non-sugar substances, such as amino acids, fats, waxes, colloids, proteins, inorganic substances, suspended solids, chromogenic substances and so on. In general, sugar factories hope to remove these non-sugar substances as much as possible before the juice is concentrated. ...
