Biodiesel is a clean burning renewable fuel made from natural vegetable oils and fats. Biodiesel is made through a chemical process which converts oils and fats of natural origin into fatty acid methyl esters (FAME).

Biodiesel is intended to be used as a replacement for petroleum diesel fuel, or can be blended with petroleum diesel fuel in any proportion. Biodiesel does not require modifications to a diesel engine to be used.

Burning fuel oil, Vehicular use, Biodiesel generators, Railway usage, Aircraft usage,Chemical products(surfactants, emulsifiers).

Kitchen waste oil, frying oil, gutter oil (UCO), swill oil, palmitic acid oil (PAO), high acid crude palm oil (HACPO), crude palm oil (CPO), palm waste recovery oil (POME), industrial grade palm oil, other animal and plant oils, etc.

Daily processing 2-5 tons, 10-12 tons. 

Single line annual capacity of 50,000-200,000 tons, 200,000-400,000 tons. 

The equipment can be customized according to your needs.

Chemical method: mainly include pretreatment, esterification, transesterification, methyl ester distillation, and methanol recovery.

Chemical method and enzymatic method.

No, it depends on the amount of water and impurities. This equipment has no requirement on the acid price of the feed. But to the water impurity content has the requirement, generally we require the moisture and impurity content is not higher than 3%.

Biodiesel produced by our machine is in line with  GB / T20828-2014, basically equivalent to American Standard ASTM D6751.At the same time in line with the BD100 national standard, the European Union standard. 

The synthetic yield of biodiesel is about 90% when the feed water content is no more than 3%. The better the quality of the raw material, the higher the oil yield.

Glycerol, plant asphalt.

Workshop without esterification process produces no waste water, while workshop with esterification process produces little waste water which is generally less than 3% of the yield.

Methanol, phosphoric acid, caustic soda.

The production process is continuous.

Mositure, Impurity, Free fatty acid and Phosphorus.

The low temperature fluidity of diesel is a very important performance for biodiesel engines operated in open air, especially at low temperatures. The freezing point of biodiesel fuel does not indicate the minimum temperature that biodiesel may be used because it begins to crystallize wax at temperatures above 5-10°C. Although the oil has a certain degree of fluidity, it is possible to block the oil pipeline and filter and then causing fuel interruption.

Using of cloud point, pour point or cold filter point to express the low temperature fluidity of biodiesel and provisioning that the indicators are selected according to region and season reflects the usage of biodiesel at low temperature. Usually we specify that the cloud temperature is 6 ℃ higher than the minimum temperature in the where biodiesel is used.

Cold filter point: It refers to the maximum temperature at which it is less than 20ml per minute when the test oil going through the filter, and the temperature has a good correspondence with the actual use of the boundary temperature and has been widely used. China also intends to combine the temperature conditions to determine the cold filter point or pour point of diesel as a fuel flow indicators at low temperature according to the region and season.

Cloud point: It refers to the temperature at which the light oil (including diesel) becoming turbid from transparent under the conditions of the cooling process. The reason for generating turbidity is that the n-alkanes begin to form tiny grains at low temperatures which cannot be observed with the naked eye.

Pour point: It refers to the temperature that the temperature at which placing the tubes flat for 5 seconds without the sample flowing pluses 3.

According to the different requirements of customers, we can do projects from 10 tons to 2000 tons.

Small production without shelling can save costs while big scale with shelling can raise the protein content of the meal, and therefore improve the quality of oil.

Oil plants pre-treatment is a series of treatments including cleaning, peeling, crushing, softening, rolling embryo, puffing, damp heat treatment and drying after which the oil is extracted. The purpose is to remove the impurities and make the raw materials into a certain structural property to meet the requirements of different technology.

Vegetable oil production process: pre-treatment, pressing, leaching, crude oil refining, oil filling.

Raw materials of vegetable oil processing : soybean, sunflower seeds, rapeseed, cotton seeds, corn germ, peanut, rice bran, sesame seeds, flaxseed and so on.

Raw materials of Animal oil processing: pig fat, sheep fat, fish fat, chicken fat and so on.

Less than 1%.

Solvent residue in leaching oil is less than 100PPM and refined oil doesn't contains solvent residue.

Normally we use N-hexane as solvent.

High oil content materials such as peanuts, sunflower seeds, rapeseed are suitable for pre-press leaching. Materials with low oil content such as soybeans is suitable for direct leaching.

The advantage of leaching is following: the meal contains less residual oil, high oil yield, cost low, high economic efficiency, and high quality of meal for the feed industry.

Different types of oil refining process is different. For example, soybean and rapeseed oil does not require dewaxing while sunflower seed oil does.

1. Crude oil contains impurities, and it's oxidized and deteriorated easily which means long-term storage is difficult.

2. There may be harmful substances in the crude oil.

3. When heating crude oil, there are many bubbles, smell, fumes which obviously affect the smell and taste of food.

Mainly contains the following sections: deacidification degumming, decolorization, deodorization and dewaxing.

The land area typically depends on the capacity of the plant. We can suggest an appropriate space to prepare after given specifications, or, can design the oil plant in-house specifically to the amount of work space available.

Cakes, phospholipids, oil feet, soap feet and fatty acids.

Refined oil meet the first grade quality indicator of China's vegetable oil standard.

Sunflower seed oil, rice bran oil, corn germ oil, tea seed oil.

Soybean: 15% to 26%

Sesame: 45% to 63%

Rice bran: 14% to 24% 

Sunflower seeds: 29% to 30%

Cottonseed: 16% to 22%

Peanuts: 45% to 50%

This depends on the continuous extraction requiring 24 hours, while the tank batch refining of the tank extractor requires 8 hours.
