Abstract

Cold Storage is a key point of cold chain logistics. In this article, the cooling capacities of water, slurry ice and seawater slurry ice were compared, and results showed that both slurry ice performed better than water. Furthermore, differences between seawater ice and slurry ice were analyzed, and experimental results showed that seawater ice has more advantages as coolant for cold storage in the coastal areas. On the basis of the study, we put forward a new design of high temperature cold storage for coastal areas (inland cities).

Highlights

Cold Storage refers to a warehouse that uses cooling facilities to create an environment with proper levels of humidity and low temperature [1]
This paper aims to study the application of seawater to produce slurry ice in high temperature cold storage in coastal areas
In comparison with high temperature cold storage using water as coolants, the application of slurry ice considerably reduces the size of tanks, pumps, pipes, and coolers due to high energy density and pumpability of slurry ice

Summary

Introduction

Cold Storage refers to a warehouse that uses cooling facilities to create an environment with proper levels of humidity and low temperature [1]. High temperature cold storage is mainly used for preservation of fresh eggs, fruit and vegetables, water colors, flowers, Chinese herbal medicines, and commodities such as high-end furniture and clothing. In China, high-temperature cold storage is most widely used in the preservation of fruits, vegetables and eggs, and mechanical refrigeration and controlled atmosphere storage are two commonly used storage and preservation technologies in fruits and vegetables preservation [3]. Controlled atmosphere storage can offer excellent preservation effect, but when applied to preservation of fruits, vegetables and eggs, economic benefits fail to meet the needs of relevant agricultural practitioners owing to its high cost. As for mechanical refrigeration, cold source mainly comes from inexpensive cold water; conveying power consumption is incurred due to large demand
