What is the refining process of a refining machine

With the increasing concern for the quality and safety of edible oil, small refined oil equipment is becoming increasingly popular in households and small and medium-sized food processing enterprises. This device can provide purer and safer edible oil, meeting consumers’ demand for high-quality food.

What is a refining machine

The refining machine equipment adopts steps such as pretreatment, pressing, refining, and storage to purify and refine soybean oil. The equipment is based on traditional technology and optimized to ensure the quality and safety of edible oil, meet the needs of consumers for high-quality food, be easy to operate, and be suitable for use in households and small food processing enterprises.

Introduction to Refining Process of Refining Machine

1: Pre treatment: Firstly, clean and screen the raw soybeans to remove impurities and unqualified beans. Then, the soybeans are crushed into small particles using a crusher for subsequent extraction and refining processes. After crushing, the beans are soaked to fully absorb water and expand, soften the texture, and improve the oil yield.
2: Pressing: Pre treated soybeans are pressed to extract the oil. The pressing methods include hydraulic oil pressing and spiral oil pressing. The pressed oil is called crude oil, which contains a certain amount of impurities and water.
3: Refining: The core part of small-scale refining oil equipment is refining equipment. This step includes degumming, deacidification, decolorization, deodorization, and other treatments to remove impurities, improve the quality and safety of the oil. Firstly, degumming treatment is carried out to remove phospholipids and other gum substances from the oil. Then, deacidification treatment is carried out to remove free fatty acids through chemical reactions and improve the stability of the oil. Next, decolorization treatment is carried out to remove pigments through activated carbon adsorption, making the color of the oil more pure. Finally, deodorization treatment is carried out to remove odors and volatile substances through high temperature and high vacuum conditions, improving the taste and quality of the oil.
4: Storage: The refined oil needs to be stored in storage tanks for subsequent filling and sales. Storage tanks are usually made of stainless steel and have good sealing and insulation properties, which can maintain the quality and taste of the oil. In addition, storage tanks are usually equipped with heating devices and mixers to maintain a uniform temperature of oil and prevent sedimentation.
5: Filling: After a period of storage, refined oil is filled into packaging containers such as bottles, barrels, etc. Filling equipment includes filling machines and sealing machines, which can efficiently fill oil into packaging containers and seal them for transportation and sales.
