Description

Technical Field

[0001] This utility model relates to a grain processing machine, specifically a top-suction polishing machine with a honeycomb-shaped main shaft for distributing ventilation holes. Background Technology

[0002] As a core piece of equipment in the grain processing industry, extending towards refined processing, polishing machines face the challenge of improving rice grain quality, reducing energy consumption, and enhancing the ease of operation, reliability, and precision of operation and maintenance during actual production. The primary function of a polishing machine is to treat the surface of rice grains, making them translucent and forming a thin gel film that produces a pearly luster, resulting in a jade-like appearance and a smooth, delicate texture after cooking. This process is called polishing. The main function of a rice polishing machine is to remove bran and powder adhering to the surface of white rice. After polishing, the rice surface has a waxy protective layer, which not only prevents bran adhesion and powder shedding during production, storage, transportation, and sales, ensuring the cleanliness and hygiene of the rice, but also improves the quality and commercial value of the finished rice, facilitates storage, maintains freshness, and enhances the edible quality of the rice. Existing top-suction polishing machines generally include a frame with a whitening chamber fixed on it. A drive motor is mounted on one side of the frame, and polishing rollers are installed inside the whitening chamber. White rice flows into the polishing chamber through the feed inlet. Simultaneously, heated water (used when the room temperature is below 15℃) from a temperature-controlled water tank flows through a flow meter and rubber tubes to the air-water mixing nozzle. High-pressure air then forms a water mist, which enters the water-receiving area of ​​the hollow main shaft. Under strong negative pressure suction, the water mist passes through the ventilation holes of the main shaft and polishing rollers, mixing with the rice and adhering to the surface of the rice grains, thus moistening and softening them. The rotating motion of the polishing rollers within the polishing chamber causes the rice grains to move continuously. During this movement, relative motion, friction, and compression occur between the rice grains, between the rice grains and the polishing rollers, and between the rice grains and the rice sieve. Because the rice grain surface is moistened and softened, this friction removes bran and blemishes from the surface. Furthermore, during the friction and compression process, the starch layer on the surface of the white rice gelatinizes and crystallizes, forming a glossy protective film, improving surface smoothness and extending the storage time of the rice. During the polishing process, fine rice bran and debris are discharged from the machine through the rice sieve holes under the strong negative pressure suction. Existing polishing machines use a hollow polishing shaft with through-holes. This structure results in uneven ventilation and water intake, low airflow, low output, and poor polishing effect. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing top-suction polishing machines by providing a top-suction polishing machine with a honeycomb-shaped distributed ventilation hole main shaft. This machine has a large ventilation volume, uniform air and water intake, and improves the polishing effect.

[0004] The technical solution of this utility model is implemented as follows: it includes a frame (1), a polishing chamber (2) is fixed on the frame (1), a motor (3) is fixed on one side of the frame (1), a feeding device (5) and an upper suction hood (4) are fixed on the top of the frame (1), a selenium discharge device (7) is provided at the bottom of the frame (1), and a polishing shaft (6) is installed in the polishing chamber (2). The feature is that ventilation holes (8) are evenly distributed in six radial directions on the polishing shaft (6).

[0005] A preferred technical solution of this utility model is that the ventilation holes (8) are arranged in a triangular pattern along the axial direction. Furthermore, any three adjacent ventilation holes (8) are arranged in an isosceles triangle pattern along the axial direction.

[0006] This invention optimizes the arrangement of ventilation holes on the main shaft of the polishing machine by adopting a honeycomb-shaped distribution of ventilation holes. This results in a large ventilation volume and uniform air and water intake, which greatly improves the atomization effect of the polishing chamber and thus enhances the polishing effect of the polishing machine.
