Oil refining workshop is divided into oil refining workshop continuous refining process, oil refining workshop semi-continuous refining process and intermittent refining process.
Our company can provide you with 30 ~ 1000TPD oil refining production line complete sets of equipment design, manufacture and installation.
1, continuous continuous refining process
In the continuous refining equipment technology, the company absorbed the advanced technology at home and abroad, combined with years of practical experience, using a unique degumming process to maximize the removal of oil in the phospholipids. The new clay automated system can make oil more reliable, full vacuum sealed refining process investment, product quality is good. According to different oil species, the different requirements of the product, the design of the best route.
(1) high degree of production automation;
(2) good quality oil products;
(3) suitable for handling more than 100 tons of soybean oil, rapeseed oil, cottonseed oil, corn germ oil, palm oil and other bulk oil.
2, semi-continuous refining process
Semi-continuous refining process is an intermittent production process and continuous production process mixed with the process, the process for small and medium oil plant. Semi-continuous refining equipment, can complete the hydration, alkali refining, washing, decolorization, deodorization process operation, and the use of electronic measurement, high-speed centrifuge deaerator, vacuum (continuous) drying and other advanced technology, mainly for pre-pressing And a leaching oil production process rapeseed oil, cottonseed oil, peanut oil, linseed oil and other vegetable oil and animal fat refining process, also applies to rice bran oil, sunflower oil and so on.
(1) refining rate is higher than the intermittent production process;
(2) equipment investment less effective;
(3) the process is simple and easy to operate.
Physical refining: mainly including hydration, decolorization, steam distillation, etc., the main removal of phospholipid hydration, decolorization mainly remove the pigment, steam distillation for the removal of odor substances and free fatty acids;
Oil quality, including the quality of crude oil and refined oil quality in two areas. For chemical refining, the quality of crude oil without any restrictions, poor quality of crude oil can also be applied to chemical refining, but refining some of the larger. In general, FFA greater than 5% of the oil, only in special conditions for chemical refining is economic. Physical refining is mainly applied to the refining of an oil containing high FFA, with such a method to get low consumption. For some oils, you can first use physical methods to refine to reduce the oil FFA content, and then use the chemical method for refining. This combination of the two methods has been applied for many years. If only after physical refining, then the quality of crude oil can not be too.
On the quality of refined oil, with physical or chemical refining, in general, can achieve similar requirements. However, for physical refining, if the pretreatment is poor, then sometimes it will cause the oil color and oxidation stability is not good.
Chemical refining: mainly including acid refining, alkali refining, in addition, there are fat, oxidation, acid refining is acid treatment, the main removal of pigment, peptizing impurities, alkali refining is alkali treatment, the main removal of free fatty acids , Oxidation is mainly used for decolorization.
Generally speaking, oil refining equipment, chemical refining is much more flexible than physical refining, almost all of the edible oil can be applied chemical refining. And physical refining, until now to, really can only apply palm oil, laurel oil and soybean oil. Although research on other fats has begun, such as corn oil, sunflower oil, peanut oil, sesame oil, olive oil, babassu oil, lard and other tallow, but most of it is only in the laboratory research stage. Cottonseed oil can not be applied to physical refining, because the pigment in the oil in the deacidification temperature, it will turn black. Soybean oil, such as the application of physical refining, must first be a good way to remove a variety of phospholipids, especially phospholipid calcium, magnesium, chrome they are present in the damaged soybean
