With the rapid development of the grain processing industry, flour machinery, as the main equipment for wheat processing, directly determines the quality and production efficiency of flour due to its performance and structural characteristics. This paper will focus on the structural characteristics of machinery and equipment for processing 30-80 tons of wheat flour per day, and analyze its application advantages in actual production.
First, the overall structure design.
The machinery and equipment that process 30-80 tons of wheat flour per day usually adopts a steel structure frame, which has a stable overall structure and strong seismic performance. The internal layout of the equipment is reasonable, which is convenient for repair and maintenance. At the same time, the equipment shell is made of high-quality stainless steel material, which has good corrosion resistance and prolongs the service life of the equipment.
2. Grinding system.
The milling system is the core part of the flour machinery, mainly including grinding rollers, grinding discs, grinding teeth and other key components. The grinding roller is made of high-quality alloy steel material, which has been precision machined and heat treated, which has high wear resistance and impact resistance. The unique design of the grinding disc and grinding teeth enables efficient grinding while reducing energy consumption. In addition, the milling system is equipped with an automatic adjustment device, which can automatically adjust the grinding roll gap according to the humidity and hardness of the raw materials to ensure stable flour quality.
3. Screening system.
The sieving system is responsible for grading and screening the milled materials to obtain flour with different particle sizes. The system adopts a multi-layer screen design, which can realize multi-stage screening and improve screening efficiency. At the same time, the screen material is made of high-quality stainless steel, which has good wear resistance and is not easy to block. The screening system is also equipped with a vibrating device, which can effectively prevent the screen from clogging and improve the screening effect.
Fourth, the winnowing system.
The winnowing system separates the impurities, wheat bran, etc. in the flour through the action of the wind to improve the purity of the flour. The system uses a high-efficiency fan and cyclone separator, which can effectively separate light and heavy impurities. At the same time, the winnowing system is also equipped with a dust removal device, which can reduce dust pollution and protect the environment.
5. Electrical control system.
The electrical control system is the "brain" of the flour machinery, which is responsible for the start, stop, monitoring and other functions of the equipment. The system adopts PLC programmable controller to realize the automatic control of the equipment. Through the touch screen operation interface, the operator can easily adjust the equipment parameters and monitor the operation status of the equipment. At the same time, the electrical control system is also equipped with a fault self-diagnosis function, which can find and deal with equipment faults in time and improve the operation stability of the equipment.
6. Security protection measures.
In order to ensure the safety and reliability of the equipment during operation, the daily processing of 30-80 tons of wheat flour machinery and equipment is also equipped with a variety of safety protection measures. If the operation process of the equipment is abnormal, the control system will automatically shut down and give an alarm to remind the operator to deal with it in time. In addition, the equipment is also equipped with safety devices such as safety shields and emergency stop buttons, which effectively prevent operator injuries and equipment damage.
