1. Continuous decolorization:
The process of adsorbing and removing part or all of the pigments, gums, etc. in the sugar alcohol solution using an adsorbent is called decolorization. The adsorbent used for decolorization of sugar solution is generally activated carbon, which has a large surface area, suitable pore structure and surface structure, strong selective adsorption capacity for pigments and gums, and is not compatible with sugar and sugar alcohols. Substances that undergo chemical reactions.
When activated carbon is in contact with sugar liquid, macromolecular substances such as pigments and colloids in the liquid can be enriched on the surface of activated carbon, which is adsorption.
Multi-unit continuous decolorization system with array valves is the same as the ordinary decolorization equipment, which is to pack the activated carbon into the separation column for use and regeneration.
2. Equipment advantages:
Granular activated carbon is regenerated at high temperature, which can realize multiple recycling and reduce the consumption of activated carbon. The equipment operation site environment is good and the degree of automation is high. Short-term investment costs are high, but long-term use can greatly reduce the average single operating cost.
