Funded by Defra – Development of Technologies to Reduce Energy in a Potato Store

In general potatoes are chilled and stored in the same systems. Unlike many other foods potatoes generate CO2 and heat due to respiration during storage. High air leakage into potato stores is one of the primary causes of high-energy costs in storage. Attention to key areas like joints in structures and doors is important. Exceptionally good sealing in buildings can lead to the build up of CO2 which can itself lead to problems with the crop and with safety. However, this is something that can be managed easily with controlled low-level ventilation. Traditionally potatoes have been stored in boxes in unrefrigerated stores.
