Three ways to refine peanut oil
1.Simple Refined
Advantage:
1. There are relatively more nutrients stored in it. Retain the aroma of edible oil.
2. The color will be slightly brighter.
3. It can realize the functions of Deacidification, Dephosphorization and Dehydration of oil products.
4. There is a dehydration tank, which can wash off the residual alkali that has not been reacted, it will extend the shelf life of the oil.
5. Dehydration: high temperature vacuum dehydration.
6. The refined oil will not foam and smoke, and there will be no sediment after long-term storage.
7. It can reach the edible standard, and the shelf life of the oil can reach 1-2 years.
Disadvantage：
1. It occupies a slightly larger area. 2. Slightly higher cost.

2.Large-scale Refinery Equipment
（Fully Refined）
Advantage:
1. The neutralization tank is used for acid and alkali refining or rinsing.
2. Decolorization tank is used to remove yellow value, red value and remove Aspergillus flavus.
3. Deodorizing tank is used to remove odors (such as rancidity, musty smell, etc.).
4. Large-scale refining equipment needs to be equipped with heat transfer oil furnace.
5. Large refineries are best equipped with mini-labs.
6.The dewaxing tank takes some times. (it is necessary to choose according to the characteristics of the pressed raw material).
7. The quality of refined oil reached to the standards for edible oil and sanitation by neutralization using phosphoric acid, water washing.
8. Oil quality is good, the oil is clear and transparent, Deacidification- Dephosphorization - Dehydration - Decolorization - Deodorization - Dewaxing, which can be sold or eaten directly.
9.Using the Roots vacuum pump, the vacuum degree is higher than that of ordinary ones, which ensures the quality of oil.
10. The shelf life of the oil can reach 2-3 years.
Disadvantage：High cost. 2. It occupies a large area.

3.Low temperature cold filtration refining
Advantage:
(1) The peanut oil low-temperature cold filtration process has low energy consumption, no steam consumption, high resource utilization rate, and no waste discharge. It is an environmentally friendly new process and meets the international requirements of "energy saving and emission reduction" and the construction of circular economy.
(2) This process retains the nutrients, physiologically active ingredients and unique fragrance in peanuts to the greatest extent, and can keep the oil clear and transparent for a long time. simple technology
Disadvantage：
1. High cost. 2. It occupies a large area.
