Embodiment 1

[0016] Embodiment 1: The syrup clarification method of the active carbon combined with calcium saccharification is carried out according to the following method: in the first step, the raw syrup is preheated and then pumped into the stirring tank, and activated carbon is added in the stirring tank, wherein, 1 kg of raw syrup is added 0.3 g to 10 g of activated carbon to obtain syrup containing activated carbon; the second step is to add phosphoric acid to the syrup containing activated carbon in the stirring tank to obtain syrup containing phosphoric acid; the third step is to pump the syrup containing phosphoric acid in the stirring tank into the retention tank, Adding calcium saccharification to the phosphoric acid-containing syrup in the residence tank to adjust the pH to obtain calcium saccharification-containing syrup; the fourth step is to filter the calcium saccharification-containing syrup in the residence tank to obtain clear syrup.

[0017] In the present invention, t...

Embodiment 2

[0019] Embodiment 2: As an optimization of the above embodiment, the raw syrup is one of redissolved syrup, mixed juice, and filtered juice.

Embodiment 3

Abstract

The invention relates to the technical field of sugar production, and relates to a method for clarifying a syrup by combining activated carbon with saccharified calcium. The method for clarifying thesyrup by combining activated carbon with saccharified calcium comprises the following steps: preheating the raw syrup, pumping the preheated raw syrup into a stirring tank, adding activated carbon tothe stirring tank according to a activated carbon / raw syrup ratio of (0.3-10) g: 1 kg in order to obtain an activated carbon-containing syrup, adding phosphoric acid to the activated carbon-containingsyrup in the stirring tank, pumping the obtained phosphoric acid-containing syrup in the stirring tank into a retention tank, adding saccharified calcium to the phosphoric acid-containing syrup in the retention tank to adjust the pH value in order to obtain a saccharified calcium-containing syrup, and filtering the saccharified calcium-containing syrup in the retention tank to obtain a clear syrup. The method for clarifying the syrup by combining activated carbon with saccharified calcium performs the synergistic effects of the activated carbon and saccharified calcium by optimizing the characteristic parameters of the activated carbon and adopting the optimal combination mode of the saccharified calcium and activated carbon, so pigments and macromolecular impurities in the syrup are effectively removed, and the quality of the finished sugar product is improved.

Description

technical field [0001] The invention relates to the technical field of sugar production, and relates to a syrup clarification method using activated carbon combined with calcium saccharification. Background technique [0002] In the sugarcane sugar production process, the quality of cane juice clarification process directly affects the quality of raw sugar and cultivated white granulated sugar. During the refining process of raw sugar, the clarification effect of re-dissolved syrup directly affects the quality and yield of refined sugar. According to the classification of clarification process in sugar refining, sugar clarification methods can be divided into sulfurous acid method, carbonic acid method and two-step method, and the corresponding clarifying agents are mainly sulfur dioxide, carbon dioxide and lime. With the improvement of people's living standards, the quality requirements for white sugar are also gradually increasing. The traditional clarification process ha...
