What should we pay attention to when using a screw oil press to press peanut oil

Here is a detailed account of what should we pay attention to when using a screw oil press to press peanut oil from preparation of raw materials, equipment setup and operation, safety precautions, maintenance and cleanliness and oil quality control.

Preparation of Raw Materials

Before using the peanut oil screw oil press, you should pay attention to proper preparation when using a screw oil press to press peanut oil. Proper pretreatment of the raw material is essential for maximizing oil extraction and ensuring high-quality oil:

Moisture Content: The moisture content of peanuts should be proper. Peanuts that are too wet may lead to excessive noise during pressing, while overly dry peanuts will reduce the oil yield.

Shell Removal: It is recommended to remove the shells of peanuts before pressing, as shelled peanuts can improve the oil extraction efficiency.

Pretreatment: Crush the peanuts into particles of some parts and steam them at high temperature. This pretreatment softens the material, which is beneficial for the release of oil.

Equipment Setup and Operation

Pre - operation Check: Before starting the machine, make sure all components are firmly installed and well - lubricated. The temperature of the oil press should be heated to the proper temperature for peanuts.

Uniform Feeding: Avoid over - feeding or uneven feeding to prevent jams. Feed the peanuts gradually to allow the press to operate stably.

Temperature and Pressure Control: Monitor the temperature of the oil press and adjust the screw clearance to maintain a consistent pressure. During operation, the temperature of the press should be maintained at proper temperature for optimal oil flow.

Safety Precautions

Foreign Object Prevention: Ensure that no stones, metal debris, or other foreign objects enter the oil press to avoid damage to the equipment.

Mechanical Safety: Never insert your hands or tools into the hopper during operation. If necessary, use a wooden stick to unclog the hopper.

Electrical Safety: Make sure the machine is properly grounded to prevent electric shock.

Maintenance and Cleanliness

Pay attention to the monitoring and maintenance of the screw oil press when using a screw oil press to press peanut oil.

Regular Cleaning: Clean the oil residues and debris on the machine daily to prevent blockages and bacterial growth.

Filter Replacement: Replace the filter elements regularly to ensure the purity of the oil.

Lubrication: Apply food - grade lubricant to the moving parts of the machine to reduce wear and tear.

Post - operation Care: After use, run dry cake residue through the press to remove the remaining oil. Then shut down the machine and clean it thoroughly.

Oil Quality Control

Prompt Cooling: Spread out the hot cakes immediately after pressing to prevent oxidation and maintain the quality of the oil.

Proper Storage: Store the extracted oil in a cool, dry place, away from direct sunlight.

The above is what we should pay attention to when using the screw oil press to press peanut oil. The automatic temperature-controlled oil press manufactured by Henan Glory is equipped with an intelligent temperature control system to adjust the temperature of the entire oil pressing process, effectively reducing oil oxidation and nutrient loss. With its stable and energy-saving characteristics, it has become an ideal choice for the oil pressing industry.
