Study of cooling experiment and simulation for edible oil storage
Du Xiao, Chen Yan, Sun Desheng
TL;DR
This study explores a refrigerant cooling method for edible oil storage, showing that manual bottom cooling improves thermal uniformity and efficiency compared to natural cooling.
Contribution
A novel refrigerant cooling method using an inner tube is proposed, with experimental and simulation results demonstrating improved thermal performance in edible oil storage.
Findings
Manual cooling reduces temperature differences and thermal stratification compared to natural cooling.
Bottom refrigerant supplying is 21.4% more efficient than top supplying.
Low flow rates (20 ml/s) provide the best thermal uniformity without significant temperature changes.
Abstract
This paper proposes a refrigerant cooling method using an inner tube in a storage tank to improve the cooling performance and thermal uniformity during the storing of edible oil. With a prototype of an oil tank in Central Grain Reserve of Zhenjiang, the experimental oil tank was built in a scale of 50:1. Both natural and manual cooling experiments were carried out for the experimental tank. The manual cooling process involved two supplying modes for the refrigerant tube (top and bottom) and four different refrigerant temperatures (10 ℃, 12 ℃, 14 ℃, 16 ℃). The experimental results show that, compared with natural cooling, manual cooling can effectively reduce the temperature difference and thermal stratification between upper and lower layers. The temperature difference is 6.79 ℃, 1.93 ℃, and 3.67 ℃ for the natural cooling, manual top supplying, and manual bottom supplying mode,…
