Automatic Peanut Oil Production Line Operation and Maintenance Guide

Qi'e Grain and Oil Machinery’s automatic peanut oil production line operation and maintenance guide provides a practical reference for site managers, production supervisors, operators, and maintenance personnel. It covers preparation before startup, production monitoring, cold- and hot-press operation, oil refining, intelligent control, shutdown cleaning, routine servicing, safe troubleshooting, and after-sales support requirements.

1. Before Starting the Peanut Oil Production Line

A consistent startup inspection helps operators identify abnormal conditions before production begins. The inspection should be completed by trained personnel and should follow the equipment documentation, site safety procedures, and the commissioning requirements provided by Qi'e Grain and Oil Machinery.

Peanut raw materials should be prepared according to the selected processing route and production requirements. Cleaning, conditioning, and other pretreatment steps should be adjusted by qualified technicians because raw material moisture, cleanliness, and quality can influence pressing stability and oil quality.

2. Monitoring Production During Operation

The automatic peanut oil production line combines pressing and refining equipment with an intelligent control system. Operators should monitor the production process through the control interface while also carrying out regular visual and operational checks. Automation can reduce routine manual work, but it does not replace supervision, cleaning, or preventive maintenance.

1. Observe material feeding: Check whether peanut material enters the process continuously and whether there is any bridging, blockage, abnormal vibration, or interruption.
2. Monitor pressing performance: Pay attention to the operating condition of the press, the flow of crude oil, the discharge of press cake, and any unusual noise, heat, or vibration.
3. Review control information: Check displayed operating parameters and alarm messages. Any abnormal indication should be assessed before production continues.
4. Inspect oil transfer: Confirm that pumps, pipelines, valves, and collection points operate without visible leakage or unexpected interruption.
5. Monitor refining: Ensure that the refining section operates in the intended sequence and that oil is transferred between process stages as designed.

3. Cold-Press and Hot-Press Operation

Qi'e Grain and Oil Machinery’s automatic peanut oil production line can be configured to incorporate cold-press and hot-press processing approaches. The appropriate process depends on the customer’s raw material, product objectives, production scale, and technical plan.

4. Refining Section Inspection and Control

The refining section is an important part of the complete peanut oil production system. It should be operated according to the process design and the technical instructions supplied for the specific configuration. Operators should confirm that each refining stage is ready before feeding oil into the next stage.

• Check the condition of tanks, pipelines, pumps, valves, and other oil-contact components.
• Confirm that process materials and operating settings match the approved production plan.
• Observe oil transfer and identify leakage, blockage, unusual noise, or unstable flow at an early stage.
• Keep refining and product-contact areas clean to support stable operation and hygiene management.
• Record relevant operating observations to support quality review and future maintenance planning.

5. Shutdown, Cleaning, and Routine Maintenance

A controlled shutdown helps protect equipment and prepares the automatic peanut oil production line for the next operating cycle. The exact order should follow the supplied operating manual and the site’s safety procedure.

Routine servicing should include inspection of fasteners, guards, seals, pipelines, electrical connections, lubrication points, sensors, and other components specified by the equipment documentation. Maintenance intervals should be determined by the actual operating environment, production schedule, and manufacturer recommendations.

6. Safe Troubleshooting and Energy-Efficient Maintenance

When an alarm or abnormal condition occurs, operators should first protect personnel and equipment. Stop the affected section when necessary, identify the alarm information, and contact qualified maintenance personnel. Troubleshooting should not involve unauthorized modification of control logic, safety devices, or equipment structure.

• Unexpected shutdown: Check the control display, power supply, emergency-stop status, and relevant protection devices before restarting.
• Unstable material flow: Inspect feeding conditions and possible blockage only after safe isolation and confirmation that moving parts have stopped.
• Abnormal noise or vibration: Stop the equipment if required and arrange inspection of fasteners, rotating parts, alignment, and other relevant components.
• Oil leakage: Isolate the affected area, clean the spill safely, and inspect seals, connections, valves, and pipelines before returning to service.
• Higher energy consumption: Review operating stability, cleaning condition, unnecessary idle running, and preventive maintenance status with qualified technicians.

7. Operator Competence and After-Sales Support

Reliable operation depends on both equipment design and disciplined site management. Operators should receive training covering startup, production monitoring, intelligent control, cleaning, emergency response, and safe maintenance. Site managers should also maintain operating records and ensure that only authorized personnel perform servicing or electrical work.

Qi'e Grain and Oil Machinery provides support covering project design, installation, technical service, and after-sales assistance. For a new project, expansion, or persistent operating issue, customers should provide the equipment configuration, operating condition, alarm information, and maintenance history so that the technical team can assess the situation more effectively.
