Precautions for using horizontal screw centrifuge in soy protein separation

Decanter centrifuge plays an important role in the process of soy protein separation. It is mainly used to separate solid protein from liquid in soy emulsion. The following are some matters that should be paid attention to when using decanter centrifuge for soy protein separation: 1. Material preparation: Before centrifugation, make sure that the soybean raw materials are properly pretreated, such as refining, heating denaturation, etc., so that the protein can be better separated from the liquid. 2. Temperature control: The separation effect of soy protein is related to temperature. It is necessary to control the feed temperature within a suitable range to optimize the separation efficiency. 3. Speed ​​setting: According to the characteristics of soy protein and separation requirements, set the appropriate centrifugal speed. Too high or too low speed may affect the separation effect. 4. Feed speed: Control the feed speed to prevent the separation effect from being reduced or the equipment from being damaged due to too fast or too slow feed speed. 5. Differential speed adjustment: Adjust the differential speed between the spiral and the drum to ensure good separation effect and solid material transportation. 6. Equipment cleaning: Keep the equipment clean, especially clean it in time after each use to avoid protein residues from depositing in the equipment. 7. Equipment maintenance: Regularly maintain the centrifuge, including lubrication, tightening, replacement of worn parts, etc., to ensure stable operation of the equipment. 8. Monitoring system: Use a monitoring system to track the separation process, such as monitoring bearing temperature, vibration, etc., to detect problems in a timely manner and deal with them. The following are specific precautions: - Prevent blockage: Make sure that the feed does not have large particulate matter to avoid clogging the feed pipe or damaging the centrifuge. - Use of liquid medicine: If liquid medicine is needed to help separation, ensure its correct proportion and use. - Safe operation: Follow safety regulations during operation to ensure the safety of operators. - Environmental protection requirements: Pay attention to environmental protection requirements during separation and prevent pollutant emissions. - Sediment treatment: Properly handle the sediment after centrifugation to avoid environmental pollution. - Equipment start and stop: Follow the correct start and stop procedures to avoid damage to the equipment due to improper operation. By paying attention to the above matters, the efficiency and safety of the horizontal screw centrifuge in the soy protein separation process can be improved.
