With the gradual improvement of people's living standards, the competition among oil factories is increasing, and everyone has higher requirements for service and oil quality. The crude oil that was directly extruded in the past can no longer meet the needs of customers. The improved small oil refining equipment of our factory can fully meet the oil refining work of small and medium oil factories, and the refined oil can enter the market.
The small edible oil refining machine is composed of refining tank, decolorizing tank and filter, oil pump and motor electric control system, which can realize the functions of degumming, deacidifying, drying and decolorizing of crude oil.
The edible oil refining machine dedicated to small oil refineries realizes the integrated process operation of dephosphorization, degumming, deacidification, dehydration and decolorization, and realizes the miniaturization and civilian use of large oil refineries. Today, complete sets of refining equipment are speeding up to enter the world's small and medium-sized refineries, and are welcomed by oil users. The oil refined by this oil refining equipment can reach the edible oil standard above China's second grade, and can be directly filled and sold!
Zhengzhou Dayang Oil Chemical Equipment Co., Ltd. has advanced research and development technology and processing equipment, which provides a strong technical and quality assurance for the excellent quality of the products. The company has a group of experts, professors, engineers and technicians who manufacture and install complete sets of grease equipment. They adopt computer design and have strong technical force. Advanced production equipment, complete detection means, stable product quality.
Features:
1. It is made of food-grade stainless steel and polished to meet my country's food machinery standards.
2. The design is simple and the appearance is exquisite, which improves customer satisfaction.
3. The operation data is all displayed by the instrument, which is easy to operate and safe to operate; ordinary employees can work on the computer after telephone training.
4. It can realize the functions of dephosphorization, degumming, dehydration, decolorization, deodorization and dewaxing of oil products. It can also perform degreasing or fractionation according to user needs.
After the initial pressing of the oil press or the processing of the extraction machine, the oil produced without filtering and refining is called crude oil, and the oil produced after filtering and refining crude oil is called refined oil. There is a big difference between the two.
Dayang Company specializes in manufacturing edible oil refining machines and edible oil pressing and refining production lines.
1. Suspended impurities: including sediment, billet, powder and other solid impurities. The existence of these impurities is conducive to the activity of microorganisms, which makes the oil easily hydrolyzed and rancid, and cannot be eaten;
2. Colloidal impurities: contain phospholipids, proteins, sugars, etc., the main ones are phospholipids. The existence of these impurities can easily lead to hydrolysis and rancidity of oils. It not only seriously affects the color and flavor of stir-fried and fried foods, but also loses the nutritional value of the oil itself, and is also toxic
3. Oil-soluble impurities: including free fatty acids, pigments, hydrocarbon waxes, aldehydes, ketones, etc., as well as trace metals and organic phosphorus, mercury, polycyclic aromatic hydrocarbons, aflatoxins, etc. caused by environmental pollution. The existence of these impurities is harmful to the human body, and some impurities have carcinogenic effects on the human body.
4. Moisture: Crude oil contains a lot of water, and the presence of water can easily make the oil hydrolyzed and rancid. Refined oil refers to refining crude oil to remove harmful and unhelpful impurities in crude oil to obtain refined oil that meets my country's quality standards
The operation process of edible oil refining machine:
Crude oil -- degumming (washing) -- deacidification (alkali refining) -- decolorization (clay adsorption) -- dehydration (heating and drying) -- deodorization -- dewaxing -- refined oil
The small edible oil refining machine is to 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 , Deodorized.
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 neutralization, distillation, solvent extraction and esterification and other methods. Alkali neutralization and steam distillation (i.e. 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 (Dewaxing, deodorization) provide good conditions.
4. Grease deodorization, grease deodorization is a process of removing odorous substances through steam distillation under high temperature and high vacuum conditions by utilizing the difference in volatilization between odorous substances in oil and fatty acid triglycerides. The principle of deodorization by steam distillation (also known as stripping) is that water vapor passes through oil containing odorous components, contacts with the vapor-liquid surface, and takes away the odorous gas. To achieve the purpose of refining oil.
Processing effect:
The oil processed by the refining machine has a transparent color, no precipitation after long-term storage, no foaming in the pot, and no oily smoke. It meets the standard of edible oil in my country and can be directly filled and sold. It is suitable for processing with supplied materials and small-scale oil processing plants.
