Performance of wet deck (ice bank) pre-cooling systems with export produce from Egypt

摘要

An evaluation for the wet deck systems installed in Egypt to pre-cool tile exported fresh produce is presented. The description of the selected pre-cooling stations is described in detail along with the principle of operation of the cooling process. The mathematical model, which describes tile cooling rates and the refrigeration load calculations is included. Three packhouses were selected for that evaluation and table grape was the product which ha: been chosen to evaluate the performance of the selected pre-cooling systems. The calculated refrigeration load for the four pallets used ranged from 64 to 80 kW. The pre-cooling curves are shown and the calculated seven eighth cooling times ranged from 6 to 8 hour:. The performance of each facility was analysed and the advantages and disadvantages of the wet deck systems am presented.
