Summary
Cool storage of potatoes by intermittent outside air cooling (OAC) was compared with cooling by continuous recirculation of artificially cooled air (RAA). RAA gave higher operating costs and greater shrinkage losses than OAC, using the same rate of ventilation (64 m3 h−1 m−3 potatoes), but allowed easier management and gave even storage temperatures. The prime advantage of RAA is the provision of safe storage beyond late-April when, owing to lack of cold, outside air at 0–3°C, it is no longer possible to operate OAC effectively.
