Peanut Oil Refining Machine

The crude peanut oil produced by the initial pressing of the oil press generally contains a small amount of impurities.These impurities need to be removed through the refining process to obtain the finished high-quality peanut oil.The following is the introduction of the specific process of peanut oil refining by Hongte Machinery:

Degumming

 

The purpose of degumming is to remove the phospholipid, sugar, protein, trace mental, and some other impurities, which have bad effect on the stability of the oil. First, the oil should be heated to 90 to 105°C, then put some phosphoric into it and stir. It mainly transfer the phospholipid to that can be compatible with water. Then add some salt water to gather the impurities, which subside to the bottom and be discharged.

Deacidification

 

Add some certain quantity of alkali to neutralize the free fatty acids. During this process, somesoap stock will be produced. The soap stock will be separated from the oil after using the centrifugal machine.

Decoloring

 

First, the deacidified oil is pumped into the decolorization tank, heated to 100-110°C, and the residual water in the oil is removed by vacuum. Then, activated clay is added. 2-4kg of activated clay is added to 1 ton of oil. Stir for 20-30 minutes at 100-110°C. Next, the mixed oil is pumped into the filter, and the decolorized oil and waste clay are obtained after filtration and separation by the filter.

Deodorizing

 

The main purpose of the deodorizer is to remove odor and some fatty acids from oil. The principle of deodorization is to use high temperature and high vacuum to remove the light component - odor. Fatty acids and odors will be pulled out by vacuum and separated in the trap.

For the product, finished refined oil:

1.The higher Smoke Point:It makes the oil to be more suitable for cooking,frying.It has less smake when cooking, so it is more safe

2.Soft taste and clear color: Through the Peanut Oil Refining Machine, the peanut oil taste get more soft bacuse losing the strong taste of the nut.And the color will be more clear and clean.

3.The refined oil more stable:After refining,the peanut oil is more stable,especially in using fring and strong cook for several times.

For the supplier:

1.Long time to stock:The refined peanut oil has a longer time to stock due to losing impurities and the easy-foxen parts.

2.Higher profit: In the market, the refined oil is more expensive, it can take the supplier the higher profit.

Because the refining equipment need to be operate in the enclosed environment, it has the following tips to notice:

1. Equipment inspection

Before operation, all components, pipes, valves, instruments, etc. of the equipment need to be inspected to ensure that the equipment is complete, intact, and without any damage.

2.Personnel training

Before operating the equipment, it is essential to train the staff to ensure that they are proficient in using the equipment and to strictly follow the equipment's user manual.

3.Emergency Management

Users should set up strict emergency management measures to prepare for all emergencies.
