Description

Technical Field

[0001] This utility model relates to the field of rice milling equipment, specifically a high-efficiency rice milling device. Background Technology

[0002] Rice milling machines are core equipment in the agricultural product processing industry, and their performance directly affects the efficiency, cost, and product quality of grain processing. With the advancement of large-scale agricultural planting and the increasing demand from consumers for high-quality grains, existing rice milling machines have gradually revealed numerous technical shortcomings, including the following: Uncontrollable output and weak scalability: Most existing rice milling machines are designed for fixed output, with small equipment producing only 0.5 to 2 tons per hour, which cannot meet the needs of large processing plants. They are also energy-intensive and economical. Traditional rice milling machines use motors with fixed speeds, and the motors run at full load regardless of the material load, resulting in high energy consumption, low rice yield, and unstable product quality. The uneven feeding of traditional rice milling machines can easily lead to material accumulation in the milling chamber, resulting in local over-grinding that produces broken rice, or local under-grinding that leaves impurities. Maintenance requires machine shutdown and affects production continuity. When the grinding components of existing rice milling machines malfunction, the entire machine must be shut down for disassembly and repair.

[0003] To address the aforementioned issues, a high-efficiency rice milling device needs to be designed that features adjustable output, low energy consumption, high rice yield, support for non-stop maintenance, versatility, and customizable nutrient retention, in order to meet the demands of modern agricultural large-scale processing and consumption upgrading.

A large raw grain silo 1 is fixedly installed on the top of the support frame 201, and the bottom outlet of the raw grain silo 1 is fixedly installed. The device is equipped with multiple material distribution bins 202. Each material distribution bin 202 is equipped with a primary rice milling device 203 at its bottom. Each primary rice milling device 203 is equipped with a secondary rice milling device 204 at its bottom. Each primary rice milling device 203 and secondary rice milling device 204 is equipped with a discharge port 205 at its bottom. Each secondary rice milling device 204 is equipped with a finished product conveying device 206 at its bottom.

[0018] Each primary rice milling machine 203 and secondary rice milling machine 204 is equipped with an independent motor for operation. The primary rice milling machine 203 and secondary rice milling machine 204 are used in conjunction, with the discharge port 205 of the primary rice milling machine 203 aligned with the inlet of the secondary rice milling machine 204. Each primary rice milling machine 203 and secondary rice milling machine 204 is connected to a pneumatic conveying pipe 3. One pneumatic conveying pipe 3 can connect to multiple primary rice milling machines 203 or secondary rice milling machines 204. A wind collector 4 is installed at the end of each pneumatic conveying pipe 3 furthest from the rice milling machine 2. Each wind collector 4 is equipped with a... The rice milling machine 2 is equipped with a rice bran collection bin 5, a feeding bin 202, a primary rice milling device 203, and a secondary rice milling device 204, forming an independent rice milling unit. The rice milling machine 2 can assemble any number of rice milling units according to production needs. The pneumatic conveying pipe 3 is equipped with multiple detachable interfaces, which can be connected to the primary rice milling device 203 and the secondary rice milling device 204 according to actual production needs.

Each rice milling unit of the rice milling machine 2, the finished product conveying device 206, and each pneumatic collector 4 are independently controlled by a PLC control system. Example 2:

[0019] like Figure 1-4 As shown, this utility model embodiment provides a high-efficiency rice milling device, wherein: Original grain silo material: stainless steel to prevent grain from getting damp and rusting. It has a feed inlet at the top and a conical hopper at the bottom. An electric discharge valve is installed at the bottom of the conical hopper to store grain to be processed. The feed rate is controlled by the electric discharge valve, and a material level sensor is used to prevent the silo from being empty or overflowing. The material distribution bin is made of stainless steel, just like the original grain bin. Its purpose is to ensure stable material buffering. It is equipped with a material leveling plate inside, and each material leveling plate is connected to a vibration motor. The material leveling plate has ventilation holes and a discharge port at the bottom that matches the number of rice milling units. Each discharge port is equipped with a solenoid valve, which is electrically connected to the PLC control system. It receives the material from the original grain bin and achieves uniform material distribution by vibration of the material leveling plate and hot air drying to avoid clumping. The discharge port is opened and closed according to the operating status of the rice milling units to ensure that the load of each group of rice milling units is balanced. The rice milling unit consists of a primary rice milling device and a secondary rice milling unit. The primary rice milling chamber removes the coarse husk, while the secondary rice milling chamber performs fine milling and impurity screening. The parallel design and bypass channel ensure uninterrupted maintenance in case of failure. Finished product conveying equipment enables stable material transfer between various components, preventing material spillage and contamination, and is used to transport milled finished rice to storage warehouses. The wind collector is a cyclone collector that uses air to transport the waste generated during rice milling to the rice bran collection bin through a wind-powered conveying pipe.

[0020] Working principle: The working process of this high-efficiency rice milling device follows a closed-loop logic of raw material storage - uniform distribution - graded milling - rice bran collection - finished product conveying. Combined with PLC intelligent control, it achieves efficient and stable operation. The specific principle is as follows: Step 1: Raw material discharge control: Grains in the raw grain silo 1 fall naturally through the bottom conical hopper. The electric discharge valve adjusts the opening according to the number of rice milling units in operation. The material level sensor prevents the silo from being empty or overflowing, ensuring a continuous and stable supply of raw materials. Step 2: Grading and grinding: Primary milling: The milling rollers of the primary rice milling equipment 203 peel off the outer husk of the grain through squeezing and rubbing. The mixture of bran and semi-processed grain enters the secondary equipment through a chute. Secondary milling: The 204 fine milling rollers of the secondary rice milling equipment further remove residual bran. The adjustable roller gap is adapted to the hardness of different grains (such as small gap for millet and large gap for corn). The built-in screen separates broken rice from the whole finished product to ensure that the quality meets the standards. Step 3: Rice bran collection: The rice bran powder generated during the milling process enters the pneumatic conveying pipe 3 through the outlet on the side wall of the equipment. The airflow of 12-15 m / s in the pipe suspends and conveys the rice bran powder to the cyclone collector 4. In the collector, the airflow rotates tangentially to generate centrifugal force. Due to its high density, the rice bran powder is thrown against the cylinder wall and falls down the wall to the rice bran collection bin 5. The clean airflow is discharged from the top, realizing the efficient separation of rice bran powder and air. Step 4: Finished rice collection. The finished rice is transported to the storage warehouse via the conveyor belt of the finished product conveying equipment 206.
