Refrigeration for Controlled Atmosphere Storage of Apples in the 21st Century

摘要

Effective controlled atmosphere storage of apples requires specialized knowledge in three important areas: first, the storage requirements of the product; second, how to refrigerate the product; and third, how to control the atmosphere within the storage space. This paper reviews the history of apples and refrigeration systems used to cool them. Next, the paper briefly reviews methods used to control the atmosphere within a sealed storage space. Then, it presents factors to consider in calculating the refrigeration load and determining the type of refrigeration system, room design features, and control strategy to manage the refrigeration load throughout the storage life of the product.
