Handpicking can be time-consuming and labor-intensive, especially if the quantity of the mixture is large. It may also be challenging to distinguish and separate the two components quickly and accurately by hand. Other methods, such as using a sieve or a fan, can be faster and more efficient.

Handpicking is less efficient for separating puffed rice from chana dal because it is slow and labor-intensive, especially for large quantities. It requires careful attention to distinguish the two, making it time-consuming. In contrast, methods like sieving or using a fan are faster and more effective, leveraging differences in size or weight for easier separation.
