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.
