Cooking oil refining machine
What are the cooking oil refining machines? The oil obtained by pressing the oil press or extracting the oil plants—referred to as crude oil or crude oil. The crude oil will contain some impurities. Some of these substances are naturally occurring, and some are produced during production or storage. They cannot be eaten directly. Cannot be sold in supermarkets or markets. Impurities in crude oil must be removed if it is to be sold on the market. Due to the different sources of impurities in crude oil, refining must be carried out in several steps under different conditions. Depending on the crude oil (soybean oil, peanut oil, sunflower oil, etc.), the refining process is divided into: degumming, deacidification, decolorization, deodorization, etc., depending on the quality requirements of the finished oil, using several steps or all refining processes, different The refining process produces different grades of cooking oil.
Scope of application of cooking oil refining machine
Applicable objects: corn oil, sunflower oil, rice bran oil, peanut oil, soybean oil, rapeseed oil, walnut oil, tea seed oil, flax oil and other vegetable oil refining
cooking oil refining machine process
Crude oil → alkali refining degumming → drying → decolorization → filtration → deodorization and deacidification → filtration → refined oil;
Main equipment components of cooking oil refining machine:
Refining pot: used for hydration degumming, neutralization and deacidification of oil.
Decolorization pot: used for adsorption and decolorization of oil.
Deodorizing pot: used for high-temperature distillation to remove the peculiar smell in the oil.
Filter: remove impurities and decolorizers in oil.
Vacuum unit: equipped with decolorization pot and deodorization pot to generate negative pressure vacuum.
Steam generator: heating water to generate steam to supply equipment for distillation
Decolorization tower; removes pigment from oil.
Deodorization tower; removes odor and free fatty acids in oil.
Crystallization tank to remove wax from vegetable oil.
Vacuum system; provides vacuum for oil refining process,
Heat conduction oil furnace; provide heat source for refining process.
Refrigerator; provides cold source for refining process. The crystallization tank freezes and crystallizes.
According to different working principles, Dayang's edible oil refining equipment is mainly divided into three categories:
1. Batch oil refining machine: The oil refining process is carried out in batches, and the oil refining in batches has limited production capacity, which is suitable for small oil factories or medium-sized workshops;
2. Semi-continuous refining machine: Some processes in the refining process, such as degumming section, deacidification section, and decolorization section, are carried out in batches and need to wait; while the deodorization section is continuous, which can save time and improve work efficiency. Suitable for medium-sized oil plants;
3. Continuous refining machine: the refining process is completely continuous, with high degree of automation, high productivity and low labor cost, suitable for large and medium-sized oil factories
4. Dewaxing section: It is suitable for raw materials containing oil and wax, and removes wax and fat to improve the quality and make the oil more clear. Such as rice bran oil, sunflower oil, etc.
5. Fractional extraction equipment: It is suitable for oil plants with different melting points of oil components. In order to improve the utilization value of each component, it is necessary to carry out fractional extraction, separate the oils with different melting points, and sell them separately. e.g. palm oil, animal oil
