What is the process of grain processing machinery?Grain processing machinery is an indispensable part of modern agricultural production, which greatly improves the efficiency of grain production and processing. Grain processing machinery is to clean up the raw grain, shelling, peeling or grinding, and screening.Machinery and equipment for granular or powder finished grains.Lets take a closer look at the grain processing machinery and equipment.
Grain processing machinery and equipment
Grain processing machinery is to clean up the raw grain, shelling, peeling or grinding, and screening to make it a granular or powder -like grain machinery of different grades.
In the Yangshao culture period of 5000 to 3000 BC, China has a stone mill and crushing stick for processing grain.The invention of Ji Jiu has been in history for about 3000 years.In the Western Han Dynasty, he invented the foot of foot, animal power and water, and had a fan of grain.The Jin Dynasty Duyu produced a "connection" that drove several crickets to process food by hydropower.At the end of the 16th century, Chinas rice milling technology and machinery had been improved.After the introduction of horizontal iron rollers at the end of the 19th century, the grain processing machinery was further developed.Europe has used wind -driven grinding in the 12th century.Hungary created steel roller grinders in the 18th century, but it was not large -scale until 1870 for processing grain.
Grain processing machinery process process
The process of grain processing can be divided into two categories:
Process 1: It is to remove and peel the raw grains such as rice, sorghum, millet, and tadpoles, and extract it into granular finished grains;
Process 2: It is to remove the skin and germ of wheat, corn, barley, buckwheat, and pupa wheat, and grind it into powder.
General process:
The raw grain first cleared the cylinder first, and then removed the various impurities after removing various impurities through the compound vibration sieve, high -speed vibration screen, the proper gravity of the stone machine and magnetic selection equipment (see the grain cleaning machinery).shell.The excreted valley mixture is sent to the rough separator.In China, the main development of the rough sieve of graphic rotation valley is mainly developed, and the differences between rice and brown rice in the aspects of granularity, gravity, friction coefficient and elasticity of rice and brown rice are separated to separate the unbolled rice and return it back to the Valley machine.The machine crushes into white rice.Then finish the finished product to remove the broken rice of the bran, that is, the finished white rice.Rural mills of rural areas are commonly used to process rice into white rice, but the rice out of rice is low and more broken rice.The process of rice milling process and the main equipment used is shown in the figure.The process of processing such as wheat is that the raw grains are cleared by the initial clearance, and the dirt that removes various impurities and dirty stains that are attached to the surface of the wheat grains through vibration sieve, wheat machine, selected machines and washing wheat machines.After the cleaning, the pure wheat is removed by the magnetic selection equipment and then enters the grinding powder to grind it into a powder. After the flat screening is sieved, the flour is extracted, and the middle material is grinded into another grinding machine.The bran is discharged after the bran brushing machine and round sieve treatment.When making special or superior flour, the powder machine is also used to separate pure and pure embryonic particles from the middle material discharged from the grinding machine and the peaceful sieve, further grind it into special and superficial flour.
The development trend of grain processing machinery
The parts in contact with grain processing machinery in grain processing machinery will be used more alloy and non -metal materials to prevent rust and ensure the clean and hygiene of the finished grain. The rack will use light metal and thin -walled steel structuresThe layout of the component is reduced to narrow the volume.The service life and interchangeability of working components and sports parts will be further improved, and the number of fastening points and parts will simplify and reduce to shorten the installation time of the working parts and reduce the scattered parts.The automatic control and safety protection device of the equipment and the equipment will be further developed.In addition, because the wheat is crushed, the flour can be used to get more colorful flour, so wheat crushing equipment also has a promising future.
