Edible oil refinery machine is designed to refine crude edible oil, preliminarily extracted from oil crops. The refined oil is of high quality, free from harmful impurities and meets the national quality standard of edible oil. After refining process, the water content, impurities, acid value and peroxide value of crude oil meet the quality standards, so it is not easy to deteriorate and can be stored for a relatively long time. The refined oil maintains the oil flavor and does not produce a large amount of oil smoke in cooking. As a professional oil refinery equipment manufacturer, we provide small and large types oil refining equipment and high-quality supporting services. Our refined oil equipment has wide application, suitable for peanut oil, soybean oil, corn oil, walnut oil, palm oil, tea seed oil, etc. and has been exported to a great number of countries in Central America, Latin America, Southeast Asia, Africa, etc.

Scope of application
Our edible oil refinery machine can be used for refining crude peanut oil, soybean oil, corn oil, walnut oil, palm oil, cottonseed oil, coconut oil, tea seed oil, sunflower seed oil, flaxseed oil, pepper seed oil, etc.
Working process of edible oil refinery machine
Generally, crude palm oil needs to be filtered by air pressure oil filter before refining process.
This oil refining machinery has the functions of degumming, deacidifying, decoloring, deodorizing and dewaxing. It contains oil refining tanks and other supporting equipment, including measurement device, automatic temperature control device, adiabatic device and material buffer device.
In the degumming process, the oil refinery machine rinses the raw oil with hot salty water.
Mix the alkali water from the alkali water tank into the crude oil. Actually, degumming and deacidification are carried out simultaneously, which is expected to take 5-6 hours.
Add active white clay into the crude oil to adsorb pigments and impurities. The initial temperature in the tank is 110 ℃, and it takes 30 minutes to cool down to 70 ℃. This procedure needs about 1 hour.
Deodorization is a process that removes substances affecting oil odor based on the difference of volatility under high temperature and vacuum. In the process, the equipment adopts the principle of steam distillation. The temperature in the tank is 220-260 ℃. Steam is introduced to extract the substances affecting the oil smell from the crude oil. The process lasts for 4 hours.
Because the newly extracted crude oil contains a certain amount of wax, it needs to be dewaxed by fractionation (heating and crystallization method). Thus, it can produce finished product of palm oil, palm olein, palm stearin etc.

Small scale edible oil refinery machine
The small edible oil refinery machine is suitable for small-scale oil mills or plants. It is specially designed for small oil refining and oil-refining complete sets of units, and realizes degumming (dehydration, dephosphorization), deacidification, decolorization, deodorization, thus achieving large-scale refinery miniaturization and industrial refining and civilian use. The refined oil can reach the level of edible oil of the second grade or above, and can be filled and sold for direct use. The refined oil equipment is suitable for refining various crude edible oil, such as peanut oil, sesame oil, sunflower seed oil, rapeseed oil, palm oil.
- This machinery can achieve integrated assembly operation of dephosphorization, degluing, decolorization, and dehydration.
- Refined oil is of good quality, clear and bright.
- High processing efficiency. The output of small oil refinery equipment reaches up to 500kg per day.
- Simple operation and labor-saving
