The vegetable oil refining machine is designed to process raw edible oil previously obtained from oilseeds. Refined oil is of high quality, does not contain harmful impurities and meets the national edible oil quality standard. After the refining process, the water content, impurities, acid value and peroxide value of crude oil meet quality standards, so it is not easy to spoil and can be stored for a relatively long period. Refined oil retains the flavor of the oil and does not produce much oil smoke when cooked. As a professional oil refining equipment manufacturer, we provide small and large type oil refining equipment as well as high-quality supporting services. Our refined oil processing equipment has a wide range of applications and is suitable for peanut oil, soybean oil, corn oil, nut oil, palm oil, tea oil, etc.
Get PriceEdible oil is essential in our daily life, no matter what kind of food you prepare. Especially in China, we have accumulated thousands of years of food culture, and the quality of edible oil directly affects the taste of food. Therefore, high quality edible oil is absolutely important. Unrefined edible oil is said to be full of impurities such as gums, pigments, waxes, phosphatides and free fatty acids (FFAs), some of which are harmful to our health. Refining of edible oils is necessary to eliminate them and provide us with first or second quality edible oil.
This oil refining machine has the functions of decolorization, deacidification, decolorization, deodorization and dewaxing. It contains oil refining tanks and other auxiliary equipment, including measuring device, automatic temperature control device, adiabatic device and material buffer device.
DecoloringBleach pigments from oil.
DeacidificationMix alkaline water from the alkaline water tank with crude oil. In fact, degumming and Deacidification are carried out simultaneously, which should take 5-6 hours.
BleachingAdd active white clay to 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 takes approximately 1 hour.
DeodorizationDeodorization is the process of removing substances that affect the odor of oil, based on the difference in volatility at high temperature and vacuum. In this case, the equipment uses the principle of steam distillation. The temperature in the tank is 220-260℃. Steam is introduced to extract substances from the crude oil that affect the oil's odor. The process lasts 4 hours.
DeparaffinizationSince newly produced crude oil contains a certain amount of wax, it must be dewaxed by fractionation (heating and crystallization method). Thus, it is possible to produce a finished product based on palm oil, palm olein, palm stearin, etc.
The small vegetable oil refining machine is suitable for small oil refineries or factories. It is specially designed for small packages of oil refineries and petroleum refineries, and carries out decolorization (dewatering, dephosphorization), deoxidation, decolorization, deodorization, thereby realizing the miniaturization of large oil refineries, industrial refining and civil use. Refined oil can reach the level of second grade edible oil or higher and can be bottled and sold for direct use. The oil refining equipment is suitable for processing a variety of raw edible oils, such as peanut oil, sesame oil, sunflower oil, rapeseed oil and palm oil.
The large-scale vegetable oil processing machine can carry out continuous and fully automatic operation and is often used in medium and large oil refineries. It is characterized by high processing efficiency, high automation and high yield. The productivity of large oil refining machines can reach from 10 to 1000 tons per day. The heat source is usually thermally conductive oil.
