Abstract

Mathematical relationships are derived between climatic and design factors in seed stores using heat balance equations modified for tropical seed storage. A computer program has been written for the Hewlett Packard 9645 to make calculation easy; this incorporates data banks of the required parameters for common store building materials and for typical tropical climates. This program has been partially verified for grain in Sri Lanka using field data. Results from program case studies highlight the relative importance of different elements of warehouse design. For seed stores, the program employs viability equations to provide least-cost combinations of warehouse cladding and seed drying regimes under varying conditions of climate and building design. In a typical 1,000-tonne seed store use of aluminium roofing and concrete block walls instead of corrugated steel cladding can save over £12,000 a year, if both drying costs and annualized building costs are taken into account.
