history of grians cleaner

Long ago, dating back to the Stone Age, people were engaged in agricultural activities and discovered the use of wind power to separate grains from husks. However, due to changes in climate and environment, sometimes there was no wind and it was impossible to use wind power. This problem has been bothering people for a long time.

About 2,000 years ago, Chinese farmers made relatively primitive wind screens that used artificial wind to separate grains from rice husks. This technology significantly improved the efficiency of agricultural production. Subsequently, screens were widely used so that people could remove impurities of different sizes.

But for a long time afterwards, there was no major breakthrough in technology in this field. It was not until after the Second Industrial Revolution that advanced technology began to promote the great development of the grain screening industry.

The use of motors and advanced industrial bases made screens easier to manufacture, and various machines began to appear. Around the 19th century, the first machine that could combine wind screening and screening began to appear in Europe. Later, after development and improvements in various countries, various wind screening cleaning machines were formed. Then, around 1897, scientists and companies, including Mr. Oliver, invented the first modern multi gravity separator, which screened items based on the principle of gravity. Since then, the basic principles of traditional grain cleaning machines have been roughly formed. Many traditional separation machines that have emerged later are mostly designed based on these three principles: wind separation, seed grader and gravity separator. At the same time, machines such as destoner have been developed specifically for removing stones. Later, the development of mining machines supplemented the field with magnetic sorting belts.

In the 20th century, with the development of optoelectronics and computer technology, the advent of color sorters was called an epoch-making event in this field. In this way, the last puzzle of grain cleaning machines was finally filled. Machines based on various technologies and styles also gradually emerged.

Starting in 1980, China introduced advanced European technology and began to produce grain cleaning machines in Shijiazhuang, Hebei Province. In the following 30 years, many factories that manufactured traditional grain cleaning machines were developed from here. Color sorters were developed in Hefei, Anhui, and many factories were born from this.

At present, China supplies more than 30% of the world's grain cleaning machines. With its excellent products of good quality and low price, it is increasingly accepted by people all over the world. The sesame seed cleaning machine and beans cleaner exported by our BEIBU Machinery Company are becoming more and more popular all over the world.
