Capital and running costs will vary according to an individual's circumstances and requirements. Therefore a direct comparison of total cost per package cooled can only be made for a specific case. Table 2 sets out typical gross capital and running costs, together with a guide throughput based on an eight hour working day.
The efficiency of the cooling and packing operation depends on close liaison between the buyer and his supplier, as in addition to the daily requirement, a reserve of cooled produce must be available for peak demands during the week.
In the field
The success of the cooling operation depends to a large extent on the way the crop has been handled in the field and the time taken to reach the cooling facility. Most crops should be cooled as soon and as quickly as possible after harvest, otherwise shelf-life will be reduced.
