Difference between Threshing and Sieving
Threshing |
Sieving |
The process of separation of grains from the Stems of grains is called threshing. |
Sieving is a simple separation technique which is used to separate the components of different sizes. |
The Process of threshing is done before the process of winnowing. |
Sieving is when there is any impurity present in Main component. |
The process of threshing is done by striking the stems of harvested crops against An hardsurface. |
Sieving is done for separation of very small size of impurity like dust and small bugs found in grains etc. |
Threshing can be carried out by manually or with the help of threshing machine. |
The sifting of small particle size of material like flour is carried out manually using sieve which has a very small holes. |
The method of threshing is done during Crop harvesting. |
A mixture of components in which solid particles of two different sizes get mixed are separated. |
These Is a important process For Separating the grains with husks from its Stems such as wheat, rice, bajra, and cereals. Etc. |
Through the small holes of sieve the small sized particles are thrown down during waving and big sized components are separated from it. Example for sieving is – flour Containing bugs. |
