Sunflower oil bleaching process

Sunflower oil bleaching process, bleaching process in the oil refining process is an essential part, bleaching steps which, today, I'll tell you what share of these problems. 
Adsorption bleaching operations in oil and sorbent contact time maximum temperature depends on theadsorption equilibrium between the adsorbent and pigments, as long as the stirring effect is good, do not need to reach adsorption equilibrium wait too long, too much to extend the time, and even make color degreegradually. The bleaching temperature is generally about 20-30 minutes in the control industry. 
Sunflower oil bleaching process, the adsorption of adsorbent pigment is in the adsorbent surface, which belongs to the heterogeneous physical and chemical reactions. Grease with good stirring to make uniform contact with the adsorbent has a chance. Is the production of steam used in the direct mixing method.

                  
The purpose of bleaching with various oils have different color issue, this is a problem because it contains a different pigment caused. For example, dark green chlorophyll so fat presents a problem; carotene so fatyellow question; during storage, carbohydrate and protein degradation leaving the oil was brown.
