4. the HFCS of de-taste after ion-exchange enters the de-taste tank of active carbon and removes the peculiar smell that resin produces;

5. concentrated HFCS after taking off taste enters evaporimeter and carries out evaporative crystallization.

1. step is specially, and HFCS is passed into the processing of decolouring of activated carbon decolorizing tank, controls the colourity of the HFCS of discharging from activated carbon decolorizing tank below 28RBU.

1. step is specially, and in decolorization, HFCS temperature is at 55-65 ℃.

2. vacuum distillation is refining is specially for step, and institute is by the HFCS injection vacuum distillation tower after decolouring, and the operating temperature of destilling tower is 85-95 ℃.

Step 3. in, from the electrical conductivity of the HFCS of ion exchange column discharging, be less than 5 μ s/cm, PH value is between 4-8;

Step 4. in, the colourity that goes out to take off the HFCS of taste tank is less than 5RBU.

Step 4. in, the light transmittance that goes out to take off the HFCS of taste tank is greater than 99%.

After evaporative crystallization, obtain massecuite dry matter content 86-89%, purity is 90-93%.

Beneficial effect of the present invention is: a kind of method of removing furfural in HFCS of the present invention, simple to operation, production cost is low, can effectively reduce the furfural content in HFCS, guarantees the quality of HFCS.The HFCS that the inventive method is produced is water white thick liquid, and light transmittance is high, and smell is pure, and mouthfeel is good, and furfural content is less than 1mg/kg.And can effectively remove the Ca in HFCS 2+, Fe 3+, SO4 2-plasma impurity, HFCS purity is high, quality better.
