Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, specifically a rice processing and drying equipment with rapid output. Background Technology

[0002] Rice is the third largest grain crop after corn and wheat. my country's annual rice consumption is around 190 million tons, and more than 60% of the population relies on rice as their staple food. The reason why rice is so popular is that it often needs to be dried during the production and processing process to prevent it from getting moldy due to moisture during storage, which would affect the safety of rice for consumption.

[0003] Existing rice drying equipment generally adopts static or intermittent drying methods, which means that the rice is first put into the drying chamber for a period of time for drying treatment. After the drying cycle is completed, the discharge port is opened to discharge the rice. While waiting for discharge, the rice that has reached the ideal degree of dryness remains in the high temperature environment and continues to be heated, which can easily lead to local over-drying, scorching, and even loss of nutrients, affecting the color, taste and commercial grade of the rice.

[0028] Example 1

[0029] As attached Figures 1 to 5The rice processing and drying equipment shown includes: a cabinet 1, a drying box 11 on the cabinet 1, a mesh cylinder 12 fixedly installed between the inner walls of opposite sides of the drying box 11, a feeding cylinder 13 on the top of the mesh cylinder 12, a discharge pipe 14 at the bottom of the mesh cylinder 12, and a fast-drying discharge mechanism, which is located on the mesh cylinder 12 and is used to quickly dry and discharge the rice.

[0030] Specifically, when drying rice, the rice is poured into the feeding cylinder 13 and then enters the mesh cylinder 12. The rice is quickly dried in the mesh cylinder 12 by a fast-drying discharge mechanism. While drying, the rice is also conveyed to the discharge pipe 14, so that the rice is completely dried when it reaches the discharge pipe 14. The dried rice can be quickly discharged through the discharge pipe 14, reducing the residence time and avoiding over-drying.

[0031] In a preferred embodiment, the feeding cylinder 13 is provided with a roller 4 inside, and multiple material distribution plates 41 are fixedly connected to the outside of the roller 4. A stepper motor 42 is fixedly installed on the outside of the feeding cylinder 13, and the drive shaft of the stepper motor 42 is connected to the roller 4.

[0032] Furthermore, after the rice is fed into the feeding cylinder 13, it falls into the area between the two adjacent distribution plates 41 above. As the stepper motor 42 starts, it drives the drum 4 to rotate slowly, causing the rice between the adjacent distribution plates 41 to rotate downwards and fall into the mesh cylinder 12. The speed of the stepper motor 42 can be adjusted through the control panel on the cabinet 1 to control the amount of rice entering, thus preventing too much rice from entering the mesh cylinder 12 at once and affecting the drying effect.

[0033] In a preferred embodiment, an exhaust pipe 5 is fixedly connected to the top of the drying oven 11, and a drain pipe 51 is fixedly connected to the bottom of the drying oven 11, with one end of the drain pipe 51 extending to the outside of the cabinet 1.

[0034] Furthermore, the steam and hot air generated during drying are discharged through the exhaust pipe 5, and the dripping liquid and debris are discharged through the drain pipe 51. The bottom of the drying zone 23 is inclined towards the exhaust pipe 5. The slope and airflow cause the debris and liquid to move towards the drain pipe 51 and discharge the debris and liquid outward. This can also be used to clean the debris and excessively wet rice. The exhaust pipe 5 has a valve that can be opened when it is necessary to discharge debris and liquid and closed when it is not necessary.

[0035] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figure 2 , Figure 3 and Figure 4 As shown below, see details:

[0036] The quick-drying discharge mechanism includes: a rotating rod 2, a spiral blade 21, a partition 22, a drying zone 23, a hot air duct 24, and a hot air blower 25. The rotating rod 2 is located inside the mesh cylinder 12, and the spiral blade 21 is fixedly connected to the outside of the rotating rod 2. Two partitions 22 are fitted around the outside of the mesh cylinder 12, and the partitions 22 are connected to the inner wall of the drying chamber 11. A drying zone 23 is formed between the two partitions 22. Multiple hot air ducts 24 are fixedly installed between the two partitions 22, and the multiple hot air ducts 24 are evenly distributed in a fan-shaped structure on the outside of the mesh cylinder 12. The cabinet 1... The interior is equipped with a hot air blower 25. The output end of the hot air blower 25 is connected to multiple hot air tubes 24 through pipes. Retaining rings 26 are fixedly installed at opposite ends of the drying box 11. The rotating rod 2 extends into the two retaining rings 26 at opposite ends and is movably connected by bearings. A sprocket a27 is fixedly installed at one end of the rotating rod 2. A stepper motor a28 is fixedly installed inside the cabinet 1. A sprocket b29 is fixedly installed at one end of the drive shaft of the stepper motor a28. A chain 210 connects the sprocket a27 and the sprocket b29.

[0037] In this configuration: Stepper motor a28, upon startup, drives sprocket b29 to rotate. Sprocket b29, via chain 210, drives sprocket a27 to rotate. Sprocket a27 then drives rotating rod 2 to rotate. Two retaining rings 26 maintain the concentricity of rotating rod 2. Rotating rod 2 drives spiral blades 21 to rotate, which then convey rice to one end of discharge pipe 14. Hot air blower 25, upon startup, generates hot airflow, which is then transported through pipes to multiple hot air ducts 24. Finally, the hot air is ejected from the hot air ducts 24. Because the hot air ducts 24 are arranged in a fan-shaped structure, the hot airflow interacts with the airflow from multiple directions. The rice is dried by hot airflow. Spiral blades 21 transport the rice, ensuring it is evenly dispersed and fully contacts the hot air during the drying process, thus improving drying efficiency. The control panel on the cabinet 1 allows adjustment of the speed of the stepper motor a28 and the temperature of the hot air generated by the hot air blower 25. By adjusting the temperature and the speed at which the rice is conveyed to the discharge pipe 14, the rice is ensured to be dried to the required degree of dryness when it enters the discharge pipe 14. This allows for adjustments to meet the moisture content requirements of different types of rice. The dried rice is then quickly discharged through the discharge pipe 14, preventing over-drying.

[0038] In a preferred embodiment, a cooling duct 3 is fitted around the discharge pipe 14. The top of the cooling duct 3 is detachably connected to the cabinet 1 by bolts. A blower 31 is installed inside the cabinet 1. The output end of the blower 31 is connected to the cooling duct 3. A ventilation net 32 ​​is installed outside the discharge pipe 14.

[0039] Furthermore, after the blower 31 is started, a normal temperature airflow is generated. The normal temperature airflow is blown out from the air outlet on the inner wall of the cooling air duct 3. The air outlet is set downward, so that the airflow passes through the ventilation net 32 ​​and enters the discharge pipe 14 and is discharged. When the rice passes through the ventilation net 32 ​​section, the rice can be cooled down, shortening the cooling time of the rice.

[0040] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
