Question

Which method is employed to separate the following?1.Stones from dal. 2. Husk from dhania and jeera seeds 3. Grains from stalks. 4. Roughage from wheat flour​

Answer 1

$\huge\frak\red{Answer}$

1. Handpicking is used to separate stones from daal.
2. Winnowing is the method of separating components of a mixture like Husk from dhania and jeera seeds.
3. Threshing is a process that is used to separate grain from stalks.
4. Sieving is the method used to separate Roughage from wheat flour.

$\huge\frak\red{explanation}$

1. Handpicking is the method where stones, dirt, husk etc are handpicked from a mixture of grains, daals, cereals etc.
2. This method is commonly used by farmers to separate lighter husk particles from heavier seeds grain.
3. In this process, the stalks are beaten to free the grain seeds.
4. It uses sieve plates for separation of coarse particles from finer particles. Wheat flour is separated from wheat bran by the method of sieving.

Answer 2

Answer:

1. Handpicking is used to separate stones from daal. Explanation: Handpicking is the method where stones, dirt, husk etc are handpicked from a mixture of grains, daals, cereals etc.
2. Winnowing is the method of separating components of a mixture containing heavier and lighter components by wind or by blowing air. This method is commonly used by farmers to separate lighter husk particles from heavier seeds grain.
3. The process that is used to separate grain from stalks etc. is threshing. In this process, the stalks are beaten to free the grain seeds.
4. The method of separation of particles from a mixture based on the difference in size of particles is known as sieving. It uses sieve plates for separation of coarse particles from finer particles. Wheat flour is separated from wheat bran by the method of sieving.
