SummaryThe moisture content of stored cottonseed depends on the relative humidity of the air which is in contact with it. This is an important consideration in using air to cool seed in storage since the seed may be moistened or dried as a by‐product of the cooling operation. Increasing the moisture tends to increase the FFA and refining loss and thus counteracts the effects of cooling.Cottonseed can be dried satisfactorily with dry air at ambient temperature or by hot undried air. In either case the economics are not favorable unless a relatively large amount of seed must be dried every season. Equipment and installation costs are relatively high, making carrying charges on the investment of the same magnitude as the probable loss because of deterioration.
