Question

How can you separate grains from the stalk?

Answer 1

Hint: Threshing is the process that is used to separate the stalk from the grain. The grain is the edible part and the stalk is the part from which the grain is attached to the plant and is not edible, so it has to be removed.

Complete step by step answer:
Threshing is the process that is used to separate the stalk from the grain. Grain which is the edible part is removed from the stalk in this process. The grain is the edible part and the stalk is the part from which the grain is attached to the plant and is not edible, so it has to be removed.
It is the main step in the process of preparation of grain. This process is followed after the reaping process. The threshing process only removes the stalk or straw but it doesn't remove the bran of the grain. In this process, the grain is beaten on a threshing floor using a flail. The traditional method or threshing involves the walking of donkeys or oxen in a circle on the grains on a hard surface. But in the modern technique, wheels of vehicles are threshed over the grains on the road.
In 1786 the industrialization of threshing started when Andrew Meikle invented the threshing machine. Nowadays, the machine has a combined harvester, which can be used to harvest, thresh, and winnow the grain.
Threshing is a highly labor-consuming process and takes a long time to be done.

Note: Reaping is the process in which the grain with stalk or straw is cut from the farm and collected after which the threshing process is started. Bran is the outer layer covering of grain and it is a hard layer.
