Method and device for reinforcing cane juice neutralization reaction by hydraulic micro-oscillation

Abstract

The invention relates to a method for reinforcing cane juice neutralization reaction by hydraulic micro-oscillation, which is applicable to a clarification technique of cane juice or liquid glucose by a sulfurous process. The method comprises the steps of preliming, primary heating, stoving neutralization, hydraulic micro-oscillation reinforced cane juice neutralization reaction, secondary heating and settling. The hydraulic micro-oscillation reinforced cane juice neutralization reaction is implemented in a way that: the cane juice or neutralized juice subjected to stoving neutralization reaction is pumped into a hydraulic micro-oscillation reinforced cane juice neutralization reaction device to subjected to hydraulic micro-oscillation reinforced cane juice neutralization reaction, and enters the steps of secondary heating and settling. The hydraulic micro-oscillation reinforced cane juice neutralization reaction device for implementing the method can change the size of the flow section of the cane juice or liquid glucose in the flowing process: the device is a cylindrical container or tubular container with inconsistent cross-sectional area. The method and device provided by the invention can reinforce the cane juice neutralization reaction, and enhance the purity of the clear juice by more than 1%; and the consumption of lime and sulfur is reduced by more than 20%.

Description

technical field

[0001] The invention relates to a sugar making process method and device, in particular to a method and device for clarifying cane juice or sugar liquid in the sugar making process. Background technique

[0002] Cane juice (sugar juice) clarification is a key link in the sugar production process. The clarification effect of cane juice (sugar juice) is related to product quality, sugar recovery rate and the amount of clarifying agent, and ultimately affects the competitiveness of sugar factories. At present, the sulfurous method clarification process commonly used in sugar factories, by adding SO 2 , lime milk and phosphoric acid, forming calcium sulfite precipitation and calcium phosphate precipitation to remove the colloid and pigment in the sugar juice, so SO 2 and Ca(OH) 2 The neutralization reaction speed and reaction degree in cane juice (sugar juice) will directly affect the clarification and decolorization effect of the mixed juice and the SO in the ...
