AI Technical Summary
The existing storage environment cannot be effectively controlled, resulting in a shortened storage time for freshly pressed edible oil, hydrolysis and rancidity affecting sales, and high turbidity of the oil, leading to material waste.
Oil storage tanks, which consist of components such as vacuum heating tanks, cooling tanks, buffer tanks, and nitrogen aeration discs, extend the shelf life of edible oils and improve their transparency through vacuum dehydration, nitrogen protection, and temperature control.
It effectively reduces the moisture content in cooking oil, decreases the risk of oxidation, extends shelf life, maintains the clarity and transparency of the oil, and avoids waste.
