Introduction to the Knowledge of the Rice Mill Industry
A rice mill is a kind of grain processing equipment that uses the mechanical force generated by mechanical devices to remove the husk and whiten brown rice. Its working principle lies in the mechanical force generated by the machinery to peel the brown rice. Through the high - speed rotation of the milling roller, pressure and frictional force are applied to the paddy, separating the husk from the rice grains and further removing the bran layer on the surface of the rice grains, thus realizing the transformation from brown rice to milled white rice.
Common Types and Characteristics
There are mainly three types of small - scale rice mills
Separate - type rice mill
It is easy to operate and has a low price. However, due to its outdated model, the quality of the milled rice is poor, and it is gradually being phased out.
Huller - mill combined rice machine
It can produce rice of good quality. However, it has a complex structure and is relatively expensive. As a result, there are few manufacturers producing it, and its market sales volume is also low.
Air - jet rice mill
It has a good cost - performance ratio and can complete the shelling and whitening processes in one go. The processed finished rice is white and shiny. In recent years, it has become the mainstream product in the market.
According to the usage, it can be divided into the following three types
rice milling machine for home
It mainly meets the needs of small-scale daily processing at home. Generally, it has a relatively small size and is easy to operate, enabling household users to mill fresh rice at home
commercial rice milling machine
It is mainly used in small rice stores, restaurants, canteens and other places. While ensuring the processing rate, it pays attention to the durability and stability of the equipment
industrial rice milling machine
It is suitable for the production lines of large-scale rice mills, and can process hundreds of tons or even more per hour. It has the ability of full automation and continuous operation. It can meet the large-scale market demand, and is equipped with advanced intelligent control systems as well as efficient impurity removal and dust removal equipment
Key components
Feeding equipment: It is responsible for uniformly and steadily feeding paddy into the rice milling chamber. Generally, it includes a feeding hopper, a feeding door, and a regulating device, and the feeding speed can be flexibly adjusted according to the processing efficiency.
The milling roller: As the core component of the rice mill, it is divided into a sand roller and an iron roller. The sand roller is mostly used in grinding-type rice mills, which grinds the cortex of brown rice through the sharp sand blades on its surface; the iron roller is commonly used in friction-type rice mills, which whitens the brown rice by virtue of high pressure. Its material, structure and rotation speed directly affect the rice milling effect and the quality of the rice
Rice sieve: It is installed on the outer side of the milling roller and is used to screen rice grains and separate rice bran. Rice sieves with different pore sizes can screen rice grains of different sizes, ensuring that the finished rice has a uniform particle size. At the same time, it assists in discharging rice bran to ensure a smooth rice milling process.
Air separation system: It uses wind power to separate the rice bran generated during the rice milling process from the rice grains, improving the purity of the finished rice, reducing the residual rice bran, and enhancing the quality of the rice.
Intelligent control system: Modern high-end rice mills are equipped with this system. Sensors are used to monitor various parameters in the rice milling process in real time, such as the milling pressure, the temperature of the rice, the flow rate of the rice grains, etc. And the operation status of the equipment is automatically adjusted according to the preset program to ensure the consistency and stability of the rice quality.
With the improvement of living standards and the improvement of rice varieties, the rice milling process has been rapidly improved. Regarding the problem that slender grain rice is prone to the phenomenon of cracked kernels, the technology of traditional rice mills has shown its backwardness. The technical characteristics of the new model rice mill include
1.Negative pressure and two-way multi-channel air intake: It can improve the utilization rate of the milling motion area per unit of production and the air volume passing through the rice milling chamber, and reduce the broken rice rate.
2.Dual-purpose machine design: The same machine can achieve two rice milling methods, namely the grinding type and the friction type.
3.Intelligent control: The Internet of Things and big data technologies are adopted to achieve remote monitoring and automated management.
4.Germ retention technology: It solves the problem of single nutrition in refined rice and meets the needs of a healthy diet.
Future development trends
1.Intelligentization: Integrate Internet of Things and AI technologies to achieve automatic control and remote management.
2.Energy conservation and environmental protection: Reduce energy consumption and pollution during the processing.
3.Multifunctional integration: Integrate functions such as rice milling, polishing, color sorting, etc.
4.Personalized customization: Meet the processing requirements of paddy rice of different varieties in different regions.
5.Health and nutrition: Develop rice milling techniques that retain the germ and nutrients.
Daily maintenance
Cleaning the equipment: After each use, promptly clean the residual rice grains and rice bran inside the rice mill to prevent mildew and the breeding of pests. At the same time, clean the surface of the equipment to keep the working area tidy.
Inspect the components: Check whether the connections of all components are firm, whether the transmission belts are loose or worn, and whether the vulnerable parts such as the milling rollers and rice sieves are damaged. If any problems are found, handle them in a timely manner or replace the components.
Lubricate key parts: Regularly add lubricating oil to moving parts such as bearings and gears to reduce wear and ensure the smooth operation of the equipment.
Regular maintenance
Calibrate parameters: Regularly calibrate key parameters of the rice mill, such as the rice milling pressure and clearance, to ensure the stability and consistency of the rice quality.
Deep cleaning: At regular intervals, carry out deep cleaning of the interior of the equipment. For example, disassemble components such as the rice sieve and the milling roller, and thoroughly remove the accumulated dirt.
Replace vulnerable parts: According to the frequency of equipment use and the wear condition of vulnerable parts, replace vulnerable components such as milling rollers, rice sieves, and belts on time to ensure the normal operation of the equipment.
Precautions
Inspect the raw materials to prevent metallic objects and stones from damaging the equipment.
Clean up the residual rice bran regularly to keep the equipment clean.
Adjust the whitening time and pressure according to the variety of paddy rice.
Conclusion
With the advancement of agricultural modernization and the upgrading of consumption, the new rice mill machine industry is facing important opportunities for technological innovation and market expansion. In the future, rice mill machines will become more intelligent, efficient and environmentally friendly, providing higher-quality solutions for grain processing.
