Rapeseed Oil Refining Machine
The rapeseed oil refining machine consists of a refining tank, a decolorizing tank, a filter, a deodorizing pot, an oil pump and a motor electric control system, which can realize functions such as degumming, deacidification, drying, decolorization, and deodorization of crude oil.
In order to meet the needs of small-scale oil mills, a complete set of oil refining units dedicated to small oil mills has been successfully developed to realize the integrated flow operation of dephosphorization, degumming, deacidification, dehydration, decolorization, and deodorization, thereby realizing the miniaturization of large-scale oil refining and industrial oil refining Civilian use, now complete sets of rapeseed oil refining machines are speeding up into small and medium-sized oil factories all over the world, and are well received by oil users. The oil refined by this rapeseed oil refining machine reaches the national edible oil standard above the second level in China, which can be used Direct filling sales!
The operation process of rapeseed oil refining machine:
Crude oil--degumming (washing)--deacidification (alkali refining)--decolorization (clay adsorption)--dehydration (heating and drying)--refined oil
The rapeseed oil refining machine can also heat and stir crude oil (peanut oil, rapeseed oil, tea seed oil, soybean oil, sunflower oil, flax oil, walnut oil, sesame oil and other edible oils) for hydration, degumming, deacidification, and decolorization , Deodorization for refining processing.
1. Hydration degumming, hydration degumming is to use the hydrophilicity of phospholipids and other peptized impurities, add a certain amount of water or electrolyte dilute solution to the crude oil under stirring, so that the peptized impurities in the crude oil absorb water and swell, coagulate And a degumming method that separates and removes. In the process of hydration degumming, the substances that can be coagulated and precipitated are mainly phospholipids, in addition to proteins, mucus and trace metal ions combined with phospholipids.
2. Alkali refining and deacidification. All kinds of unrefined crude oils contain a certain amount of free fatty acids. The process of removing free fatty acids in oils is called deacidification. Deacidification methods include alkali refining, distillation, solvent extraction and esterification and other methods. Alkali refining and steam distillation (that is, physical refining) are widely used in industrial production.
3. Grease decolorization, the adsorption decolorization of grease is to use certain substances with strong selective adsorption to pigments (such as bleaching earth, activated clay, activated carbon, etc.) to absorb pigments and other impurities in grease under certain conditions. So as to achieve the purpose of decolorization. The oil treated with adsorbent not only achieves the purpose of improving oil color and removing gum, but also effectively removes some trace metal ions and some substances that can cause hydrogenation catalyst poisoning in oil, so as to further refine the oil (hydrogenation, deodorization) provide good conditions.
4. Oil deodorization, oil deodorization is the process of using the difference between the volatilization of odor substances in oil and triglyceride fatty acid esters, and deodorizing substances with the help of steam distillation under high temperature and high vacuum conditions. The principle of steam distillation (also known as steam stripping) deodorization is that water vapor passes through oil containing odorous components, and the vapor-liquid surface contacts, and the water vapor is saturated by the volatile odorous components, and according to its partial pressure The ratio escapes, so as to achieve the purpose of removing odor components.
Processing effect:
The oil processed by the rapeseed oil refining machine has a transparent color, no precipitation after long-term storage, no foaming in the pot, and no oily smoke. It meets the national edible oil standard and can be directly filled and sold. It is suitable for processing with supplied materials and small-scale oil processing factory use.
Features:
1. It is made of food-grade stainless steel and polished; it meets the national food machinery standard.
2. Simple design, exquisite appearance, improve customer satisfaction.
3. The operation data are all displayed by the instrument, the operation is simple and the operation is stable; ordinary staff can work on the machine after telephone training.
4. It can realize the functions of dephosphorization, dealkalization, dehydration, decolorization and deodorization of oil products.
