Canola oil extraction machinery is an indispensable part of the oil processing industry. They use a series of complex process steps to efficiently extract the oil from canola. Canola oil extraction machinery is a comprehensive equipment system that integrates cleaning, crushing, steaming, pressing and refining. These equipment separates the oil from canola by physical or chemical methods, and after refining, obtains canola oil that meets edible standards. These machines include vibrating screens, stone removers, crushers, steaming and frying pans, oil presses, refining equipment, etc. Each link is crucial and together constitutes a complete extraction process.
Canola oil extraction process
1. Cleaning: First, the picked canola needs to go through the cleaning step to remove impurities and bad fruits. This step usually uses equipment such as vibrating screens and stone removers to separate impurities such as soil, stones, and straw from the canola through mechanical vibration and screening to ensure the purity of the raw materials for subsequent processing.
2. Drying: The cleaned canola contains a certain amount of moisture and needs to be dried. The dryer evaporates the moisture in the canola through hot air circulation, reduces its moisture content, and improves the efficiency of oil extraction. The dried canola should meet a certain moisture standard, usually 6%~8%.
3. Crushing: The dried canola is sent to the crusher for crushing. The crusher crushes the canola into smaller particles, increases its surface area, and is conducive to the outflow of oil during subsequent oil extraction. The crushed canola particles should be of moderate size to ensure the pressing effect.
4. Steaming and frying: The crushed canola enters the steaming and frying pan for steaming and frying. Steaming and frying can further destroy the cell structure of the canola and make it easier for the oil to flow out. At the same time, steaming and frying can also adjust the temperature and humidity of canola and improve the efficiency of pressing. The steaming and frying pan is usually equipped with a heating device and a stirring device to ensure that the canola is heated evenly.
5. Pressing: The canola after steaming and frying is sent to the oil press for pressing and oil extraction. The oil press squeezes the oil out of the canola by mechanical force. Common oil presses are screw oil presses and hydraulic oil presses. The screw oil press squeezes the oil out of the canola by the rotation and advancement of the screw shaft; while the hydraulic oil press directly presses the canola by the pressure generated by the high-pressure oil pump. The crude oil obtained by pressing contains certain impurities and cake residues and needs further processing.
6. Refining: The crude oil obtained by pressing cannot be eaten directly and needs to be refined. The refining process includes steps such as degumming, deacidification, decolorization, and deodorization. Degumming is the process of removing phospholipids and other colloid-soluble impurities in oils and fats; deacidification is the process of removing free fatty acids in oils and fats; decolorization is the process of improving the color and transparency of oils and fats; deodorization is the process of removing odors and volatile components in oils and fats. These steps are usually completed using equipment such as hydration tanks, mixers, centrifuges, decolorization tanks, deodorization towers, etc. The refined canola oil has stable quality and meets edible standards.
When choosing canola oil extraction machinery, multiple factors need to be considered to ensure the applicability and efficiency of the equipment. First, the appropriate equipment model and quantity should be selected according to the production scale. Secondly, attention should be paid to the quality and stability of the equipment, and suppliers with good reputation and after-sales service should be selected. In addition, the energy consumption and environmental performance of the equipment should be considered, and energy-saving and environmentally friendly equipment should be selected to reduce production costs and environmental impact.
In summary, canola oil extraction machinery and its extraction process are a complex and delicate process. Through scientific and reasonable process flow and advanced equipment technology, high-quality canola oil can be extracted efficiently and stably. With the continuous advancement of science and technology and the increasing requirements of consumers for food safety, canola oil extraction machinery will become more intelligent, efficient and environmentally friendly in the future.
