Step 1: Concept Decortication is the process of removing the outer shell (hull) from groundnut pods to obtain the kernels.
Step 2: Meaning Hand-operated decorticators are designed for small-scale use where manual labor is the primary power source.
Step 3: Analysis These machines usually employ an oscillating sector with a sieve to crush the pods against a stationary grate. A typical manual unit can process roughly 40 to 60 kg of groundnuts in one hour.
Step 4: Conclusion The output capacity for such an implement is 40-60 kg/h.
Final Answer: (C)
