All edible oil refining processes, both batch and continuous, benefit from the usage of soap adsorbent. In neutral oil, soap adsorbent can be used to remove soap particles, metal, and phospholipids.

Process: 

Since we are unable to remove soap that has become embedded on the heating coil, stirrer blade, or vessel side, we apply a hot water pre-wash after removing the soap from the neutral oil in the neutralizer.

It is possible to reduce a larger amount of soap adsorbent by pre-washing to get rid of any settling soap. Bleachers, as opposed to neutralizers, yield the finest results.

Heat neutral oil to 85–90ºC while stirring continuously. Oil moisture content should be at least 0.20–0.30%. In neutral oil, the soap ppm must be computed. The dosage of soap adsorbent needed is around 0.08–0.15%, depending on the soap ppm in neutral oil. Typically, 1 kilogram of soap adsorbent is needed for every 1 MT of neutral oil.

The necessary amount of soap adsorbent is charged at 85–90ºC while stirring continuously for 20–30 minutes. After that, you may go on to the bleaching procedure.

Fundamental benefits:

1. By using water washing, you may prevent neutral oil loss.
2. One alternative to removing both primary and secondary water wash is to use soap adsorbent, which is simple to apply.
3. Centrifuges remove expensive equipment, related operations and maintenance costs, and related issues.
4. Fuel may be saved for water heating.
5. Power requirements for the pump, mixture, and centrifuge may be reduced.
6. Time may be spared. Bleaching earth powder can be made more effective.
7. You may overcome the issue of water pollution, which is a modern global concern, by employing soap adsorbent.
