The peanut oil pressing process mainly includes the following steps:
1. Raw material preparation
Peanut selection: Choose large peanuts with rich aroma, full grains and high quality as raw materials. When purchasing these peanuts, they must undergo strict sampling and inspection to ensure the high quality of the raw materials and the natural aroma of peanut oil from the source.
2. Preprocessing
Shelling: Put the harvested shelled peanuts into a professional shelling machine to remove the shells and obtain peanuts. This step can significantly improve work efficiency.
Crushing: Use machinery to crush peanuts to a moderate size, slightly larger than sesame seeds, for subsequent steaming, frying and pressing.
3. Steam and stir-fry
Steaming: Put the crushed peanut shells into a steamer and steam them until cooked, which will take about 3 to 5 minutes. The purpose of this step is to soften the peanut base to facilitate subsequent frying and pressing.
Stir-fry: Put the steamed peanuts into a large iron pot and stir-fry until golden and bright and fragrant. During the frying process, the heat and time must be strictly controlled to ensure the oil yield of the peanut base and the aroma of the peanut oil.
4. Pressing
Pressing to produce oil: Put the fried peanut shells into a press and press. During the pressing process, peanut oil will flow out from the oil mixing port and peanut cake will be produced at the same time. The selection of the press and the setting of pressing conditions have an important impact on the yield and quality of peanut oil.
5. Refining and Filtration
Crude oil processing: The crude oil obtained by pressing usually contains some impurities and peanut foam, and needs to be refined and filtered to improve purity.
Refining: Using a series of chemical and physical methods to remove impurities such as phospholipids, non-phosphorus colloids, and high melting point saturated fats in crude oil, and to improve the color and smell of the oil.
Filtration: Use an oil filter to filter the refined peanut oil to remove tiny impurities and particles to ensure the clarity and purity of the peanut oil.
6. Storage and preservation
Cold storage: The pressed peanut oil needs to be kept at low temperature during storage to prevent oxidation and deterioration.
Nitrogen filling preservation: In order to extend the storage period of peanut oil and maintain its natural quality, nitrogen filling preservation method can be adopted to reduce the contact between oxygen and peanut oil.
To sum up, the process of peanut oil pressing includes multiple steps such as raw material preparation, pretreatment, steaming and frying, pressing, refining and filtration, as well as storage and preservation. Each step requires strict control of conditions and operating specifications to ensure that the final peanut oil is of high quality and rich in flavor.
1. Surface quality and structural strength
Surface quality: The surface of the oil press should be smooth and flat, without obvious scratches, sand holes, unevenness or paint peeling. This reflects the process level and quality control of the oil press during the manufacturing process.
Structural strength: The welding of the oil press should be uniform and firm, without welding defects such as leaking welding, false welding, slag inclusion, etc. This ensures the overall structural strength of the oil press, making it less likely to deform or damage during long-term use.
2. Material selection
Material of key components: The key components of the oil press, such as the pressing chamber and the pressing screw, should be processed with materials with good wear resistance. For example, materials such as alloy steel usually have wear resistance and pressure resistance, which can ensure the stable operation of the oil press during high-pressure and high-speed pressing.
Inner liner material: For the inner liner of the oil press that is in direct contact with food, food-grade materials such as 304 stainless steel should be used. This material has the characteristics of high temperature resistance, wear resistance, and corrosion resistance, which can ensure that the squeezed oil is pure and free of impurities.
3. Transmission system
Transmission belt: The transmission belt should be free of cracks and aging to ensure the stability and reliability of the transmission system.
Chain and gear: The chain should be tightly connected and not loose; the tooth surface of the gear should be smooth and free of wear. This can ensure that the transmission system will not slip or jam during the pressing process, thereby improving the pressing efficiency.
4. Operation status
Steadyness: When the oil press is running, it should remain stable and free of abnormal vibration. This can ensure the stability and safety of the oil press and reduce the possibility of failure.
Noise control: The noise of the oil press should be controlled within a reasonable range, usually not exceeding 85dB (A). This can ensure the comfort of the operator and reduce the impact of noise on the surrounding environment.
5. Oil output effect
Oil output smoothness: The oil press should be able to squeeze out oil smoothly without blockage or oil leakage. This can ensure the pressing efficiency and improve the oil output rate.
Oil purity: The squeezed oil should be pure and free of impurities, without excessive water or sediment. This can ensure the quality and taste of peanut oil and meet the needs of consumers.
6. Quality Certification The oil press should have relevant quality certification marks, such as ISO quality system certification, etc. This can reflect the quality control level of the oil press during the manufacturing process and ensure the safety and reliability of the product.
