Tempering in seed drying refers to

Correct option is B

✅ (b) Small pause between stages of drying [Moisture Equalization] • Tempering involves resting the seed batch between drying stages. • Allows internal moisture to redistribute uniformly from the center to the surface. • Prevents cracking or damage, especially in high-moisture seeds like paddy and maize. • Enhances efficiency and safety of the drying process.
❌ (a) Moisture vapour pressure • Refers to physical property affecting drying but not the process of tempering itself.
❌ (c) Equilibrium moisture content • It is the stable point where seed moisture equals ambient humidity. • Not directly related to the pause in drying.
❌ (d) Moisture gradient • Describes variation in moisture across the seed. • Tempering helps reduce this gradient but is not defined by it.
