The continuous decolorization process has the following characteristics:

1.    The grease and the decolorizing agent are in full contact under dynamic conditions, and the decoloring efficiency is high,which can reduce the amount of the decolorizing agent;

2. The material continuously and uniformly enters and exits so that the decolorization time is balanced to avoid the oxidation of oil and the rise of acid value;

3. The special agitating structure of the decolorizing tower prevents the material from forming a dead angle to avoid the precipitation of the adsorbent and the blockage of the pipeline;

4. Continuously sealed filter equipment realizes automation of unloading cake and reduces labor intensity;

5. Advanced blow drying technology reduces the oil content of the filter cake.
