How should the olive oil can be dried after cleaning?

1. Preliminary treatment after cleaning
1. Empty the accumulated water:
After cleaning, first open all the drain and sewage outlets of the oil tank to ensure that the accumulated water in the tank is completely discharged.
For oil tanks with slope design, use the slope to help the accumulated water to drain naturally.
2. Ventilation:
Open all manholes, vents and breathing valves of the oil tank to ensure air circulation in the tank and accelerate the evaporation of water.
During the ventilation process, a fan or blower can be used to blow dry air into the tank to further promote the evaporation of water.
2. Drying method
1. Natural drying:
Let the oil tank dry naturally under well-ventilated conditions. This method is simple and low-cost, but it takes a long time, usually several days.
Applicable to situations where the drying speed is not required.
2. Hot air drying:
Use an industrial hot air blower or drying equipment to blow hot air into the oil tank to accelerate the evaporation of water.
The hot air temperature should be controlled within the safe temperature range of olive oil to avoid damage to the tank or residual olive oil.
Hot air drying has high efficiency and is suitable for scenes that require fast drying.
3. Nitrogen drying:
For oil tanks with higher requirements, nitrogen can be used for drying. Nitrogen drying can not only quickly remove moisture, but also remove oxygen in the tank to prevent olive oil from oxidizing.
Inject nitrogen through the air inlet of the oil tank and discharge it from the air outlet. Cycle several times until the moisture in the tank is completely replaced.
Nitrogen drying is suitable for large oil tanks or situations where the quality of olive oil is extremely high.
3. Inspection after drying
1. Visual inspection:
After drying is completed, enter the oil tank for visual inspection to ensure that there is no obvious moisture residue in the tank.
Check whether there are water droplets or traces of moisture on the tank wall, tank bottom and weld.
2. Humidity detection:
Use a humidity detector to detect the air in the tank to ensure that the humidity in the tank meets the safety standard.
The humidity detector can accurately measure the humidity of the air in the tank to ensure the drying effect.
4. Precautions
1. Avoid secondary pollution:
During the drying process, avoid bringing dust or other pollutants into the oil tank.
Ensure that all air or gas entering the oil tank is clean.
2. Safe operation:
When entering the oil tank for inspection or operation, safety regulations must be followed to ensure good ventilation and prevent suffocation or poisoning.
Operators should wear appropriate protective equipment.
3. Recording and maintenance:
Record the date, method and results of each cleaning and drying to facilitate tracking of the maintenance history of the oil tank.
Regularly check the sealing and anti-corrosion layer of the oil tank to ensure the long-term safe use of the oil tank.
