In this video is on topic of separation of components from the mixture. Hand-picking-Hand picking is the method of separating easily identifiable material from a mixture. The components of the heterogeneous mixture can be separately identified from each other. And they can be separated from each other by by using hand picking. Sieving-A mesh strainer, also known as sift, commonly known as sieve, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal.[1] The word "sift" derives from "sieve". In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate suspended solids from a liquid by filtration. Threshing-Threshing is the process of loosening the edible part of grain (or other crop) from the chaff to which it is attached. It is the step in grain preparation after reaping. Threshing does not remove the bran from the grain.[1] Threshing may be done by beating the grain using a flail on a threshing floor. Another traditional method of threshing is to make donkeys or oxen walk in circles on the grain on a hard surface. A modern version of this in some areas is to spread the grain on the surface of a country road so the grain may be threshed by the wheels of passing vehicles.[2] Hand threshing was laborious, with a bushel of wheat taking about an hour.[3] In the late 18th century, before threshing was mechanized[4], about one-quarter of agricultural labor was devoted to it.[5] Industrialization of threshing began in 1786 with the invention of the threshing machine by Scotsman Andrew Meikle. Today, in developed areas, it is now mostly done by machine, usually by a combine harvester, which harvests, threshes, and winnows the grain while it is still in the field.[6][7] The cereal may be stored in a barn or silos. A threshing bee was traditionally a bee in which local people gathered together to pitch in and get the season's threshing done. Such bees were sometimes festivals or events within larger harvest festivals. Today the original purpose is largely obsolete, but the festival tradition lives on in some modern examples that commemorate the past and include flea markets, hog wrestling, and dances.
