Threshing - Agriculture is a very important practice for the existence of human life. It provides food to eat and includes so many processes to produce the food from filed to granaries. Most of the thing we produce are full of impurities. we need to separate them using different methods like centrifugation, threshing, winnowing , and many more. Threshing is one of the major process that occurs during agricultural practice and used for separation of mixture. Threshing is very necessary for agricultural practice for getting the edible part. This article will describe the process of threshing and also contains differences with the winnowing.

When we look into historical events threshing is the most time-consuming process for farmers. And a lot of man effort is required for this job. At the very beginning, the shells of grains are removed with the help of a hand. and later when the volume of grains increases, beating with the help of sticks is a common practice that is used.

Mechanization made the difficult process an easier one. Damage to grain has been reduced with the introduction of machines for agricultural practices. The introduction of the thresher machine was one among them. A Thresher machine is farm equipment that removes grains and seeds from the husk or stalk. And it reduced the effort of man’s labor a lot.

What Is Threshing?

Do you know what is threshing meaning in Hindi? The meaning of threshing in Hindi is ‘Taadana’. Synonyms for it are beating, separating, harvesting, and many more. This means It is a process that is used for the separation of grain from the stack where it grows. By the process of threshing, the edible portion of that crop is loosened and the non-edible portion that is fiber portion is not loosened. This process is done before winnowing and after harvesting. During ancient times, this process was done by beating with a thrash manually. And after which the grains were collected and to remove the straw, winnowing is used. During the winnowing process, the air current is blown and it will remove the light-weighed particles from it and the remaining portion will contain only the grain particles.

Later Andrew Meikle invented the threshing machine. It made the process easy. It consists of a spinning chamber of wooden mixtures and is supported by piles of grain. Threshing machines work on the theory of the Meikles machine. In the threshing machine, the straw remaining is removed by which it contains a sawtooth-like drum and which will force the remaining waste and the grain in the set of rollers through a strainer that will then separate the chaff from the grain before the process of winnowing. Now with the help of combined harvesters, it will do the process of harvesting, threshing, and winnowing. The threshing machine price is not affordable for small and marginal farmers. so without purchasing the whole machine they use it and pay money according to the time taken in the whole threshing pricess.

Threshing Definition

The process used by the farmers working in the agricultural sector for separating grains from the stalks after the harvesting process is done. In ancient times it is done by beating the grain with a stick on any clean and hard surfaces and it needs great effort also. Now the threshing is done with help of threshing machines.

Examples Of Threshing

There are some other examples of threshing like handpicking the pebbles, broken grains, insects that are found in the rice, and removing some pulses and wheat. Threshing is also used for the separation of seeds from the harvested stalks.

Threshing And Winnowing

The very important harvester function is threshing and grain loss and the degradation of a crop will significantly affect the threshing process. There are four types of principles are associated with the threshing process that are scratching, scrapping, combing, and grinding. Through a subsequent combing process, the grain loss from the cleaning process can be controlled. After the harvesting browsers threshing is done and immediately after the threshing process winnowing is done for the separation of chaff from the grain.

The main difference between threshing and winnowing can be given as. The threshing process involves the beating out of grains from the stem of the plant. While winnowing involves the separation of grains from the chaff. Winnowing is a process done after the threshing process is completed with the help of wind.

What Are The Differences Between Threshing And Winnowing?

Both threshing and winnowing are used for agricultural purposes for the removal of unwanted substances from the grain. The main difference between threshing and winnowing can be explained as.

  • The threshing process involves the beating out of grains from the stem of the plant. While of winnowing involves the separation of grains from the chaff.
  • Only when the threshing process is completed winnowing process starts.
  • The winnowing process can be done with the help of wind while threshing is done by striking the harvested crops by using a hard surface.
  • Threshing is done with the help of a thresher machine and winnowing is done with the help of a winnowing machine. Two different machines are used for the process even though their purpose is the same which is the removal of the unwanted substance.
  • And also winnowing is a process that is done immediately after the threshing process.

NCERT Chemistry Notes:

Frequently Asked Question (FAQs)

1. What is called threshing?

Threshing is one of the steps in grain preparation after reaping. It is a process for loosening the edible part of a type of grain from the straw or husk attached to it. And this process does not involve the removal of bran. Now threshing machines are used for the removal of grain. Winnowing is another process that came after the threshing process and it will further remove the non-edible portions of the grain.

2. What is threshing and its types?

The process of detaching the kernel from the pods or panicles by impact and rubbing action. It can be accomplished by trading the harvested one with the feet of man or hooves of animals. But now the threshing process is done with the help of a threshing machine. It can be achieved by three methods: Rubbing action,  Stripping, and Impact.

3. What is threshing in science class 6?
The process by which we separate grains from the stalk is known as Threshing. The grains are loosely attached to the stalk therefore when the stalks are beaten to a hard surface the grains get separated.
4. What is the difference between threshing and Harvesting?

Harvesting is the process of cutting and segregating the crop after the maturity period.  farmers are very happy in this period because of the fruits of their hard work. however, threshing is the separation of grains from chaffs.

5. What is example of threshing?

Handpicking the pebbles, broken grains,  insects that are found in the rice, and removing some pulses and wheat are some example of thrushing.
