Description

Technical Field

[0001] The utility model relates to the technical field of grain processing, in particular to a vertical sand roller rice mill. Background Art

[0002] The working principle of the rice mill is that after the brown rice passes through the whitening chamber of the rice mill, the internal pressure and the rotation of the sand roller or iron roller allow the rice grains to fully rub against each other, the rice grains against the screen plate, and the rice grains against the rice roller, so as to remove the rice skin on the surface. After proper watering, the rice will have a smooth and shiny appearance.

[0003] The structure of the currently commonly used vertical sand roller rice milling machine is usually that the rice milling sand roller is vertically installed in the machine body, and a whitening chamber is formed between the rice milling sand roller and the screen plate. During operation, the main shaft rotates, and the material enters the whitening chamber from above for whitening. However, when the material is relatively moist and the moisture content does not meet the standard, the connection between rice and husk, and between rice and rice is relatively tight, which is prone to adhesion, resulting in poor rice milling effect; at the same time, the rice milling sand roller is an integral structure, and the ventilation effect in the whitening chamber is poor, resulting in a small airflow in the whitening chamber, which easily makes most of the bran powder in the material in the whitening chamber unable to be discharged in time, thereby increasing the bran powder content and easily clogging the whitening chamber, thereby affecting the rice milling effect.

[0023] In the prior art, when the material is damp and the moisture content does not meet the standard, the rice and husk, as well as the rice itself, are tightly connected, which can easily cause adhesion and poor rice milling results. Furthermore, the rice milling emery rollers are integral structures, which results in poor ventilation within the whitening chamber. This leads to low airflow within the whitening chamber, which can prevent most of the bran from being discharged in time. This increases the bran content and can easily cause clogging of the whitening chamber, thus affecting the rice milling effect. Therefore, the inventors have developed a vertical emery roller rice milling machine that can dry the material without affecting the rice milling effect, while also assisting in the discharge of bran from the whitening chamber, preventing clogging and improving the rice milling effect.

[0024] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0025] Please refer to Figure 1 The embodiment of the present invention provides a vertical sand roller rice milling machine, comprising a rice milling component 100 and a drying and cleaning component 200. The rice milling component 100 is used for milling rice, and the drying and cleaning component 200 is used for drying materials and cleaning bran powder.

[0026] Please refer to Figure 2The rice milling assembly 100 includes a rice milling box 110, a dumping guide 120 and a rice milling sand roller 130. The dumping guide 120 is fixedly connected to the top of the rice milling box 110, and the rice milling sand roller 130 is fixedly connected to the bottom of the dumping guide 120. The rice milling sand roller 130 is used for rice milling; the drying and cleaning assembly 200 includes a drying box 210, a stirring member 220, a heating plate 230, a solenoid valve 240 and a cleaning air box 250. The drying box 210 is fixedly connected to the top of the dumping guide 120, the stirring member 220 is fixedly connected to the inside of the drying box 210, the heating plate 230 is evenly connected to the inner wall of the drying box 210, the solenoid valve 240 is installed at the bottom of the drying box 210, one end of the cleaning air box 250 is evenly arranged on both sides of the rice milling sand roller 130, and the other end of the cleaning air box 250 extends out of the rice milling box 110. When in use, pour the material into the drying box 210, start the stirring member 220 and the heating plate 230, so that the material is fully stirred in the drying box 210, and at the same time, the heating plate 230 makes the material evenly dried until it reaches the qualified moisture content, open the solenoid valve 240, and let the material fall into the rice milling box 110, pass through the pouring guide 120, and fall into the rice milling sand roller 130, start the rice milling sand roller 130, so that it can be milled, and then start the cleaning air box 250, so that the bran powder generated during the rice milling process is sucked into the cleaning air box 250, and the cleaning air blows away the bran powder. The rice milling chamber 110 is vented through the impurity-clearing air box 250, allowing most of the bran to be discharged promptly, thus preventing clogging of the rice milling sand rollers 130. The material is promptly dried by the drying chamber 210, preventing it from sticking together and affecting the rice milling process. The impurity-clearing air box 250 prevents clogging of the rice milling sand rollers 130, resolving the problem of adhesion between rice and husk, or between rice and rice, which can occur when the material is damp or its moisture content does not meet the standard. This also addresses the problem of clogging of the whitening chamber, which can affect the rice milling process. A preliminary screen 260 is fixedly connected to the bottom of the drying chamber 210. The preliminary screen 260 is used for preliminary screening of the material. Guide angle plates 140 are fixedly connected to both sides of the bottom of the rice milling chamber 110. The processed rice falls through the guide angle plates 140 to the outside of the rice milling chamber 110, facilitating collection of the processed rice. An inlet pipe 270 is fixedly connected to the top of the drying chamber 210. The inlet pipe 270 is used to dump materials into the drying box 210 .

[0027] Please refer to Figure 3The stirring element 220 includes a stirring motor 221, a rotating shaft 222, and a stirring roller 223. The stirring motor 221 is fixedly connected to the top of the drying chamber 210, the rotating shaft 222 is fixedly connected to the output end of the stirring motor 221, and the stirring roller 223 is fixedly connected to the peripheral side of the rotating shaft 222. Starting the stirring motor 221 drives the rotating shaft 222 to rotate, which in turn rotates the stirring roller 223, stirring the material and enabling the heating plate 230 to dry the material evenly. The rice-milling motor 131 is fixedly connected to the mounting screen plate 122. A mounting cover 134 is sleeved around the periphery of the rice-milling motor 131, and the tilting angle 121 is fixedly connected to the mounting cover 134. The mounting cover 134 protects the rice-milling motor 131. The tilting guide 120 includes the tilting angle 121 and the mounting screen plate 122. The mounting screen plate 122 is fixedly connected to the top of the rice-milling chamber 110, and the tilting angle 121 is fixedly connected to the mounting screen plate 122. The tilting angle 121 guides the material onto the mounting screen plate 122, where it then enters the rice milling emery roller assembly 130. The rice milling emery roller assembly 130 comprises a rice milling motor 131, a vertical emery roller 132, and a rice milling screen 133. The vertical emery roller 132 is fixedly connected to the output end of the rice milling motor 131, and the rice milling screen 133 is sleeved around the circumference of the vertical emery roller 132. A rice milling chamber is formed between the rice milling screen 133 and the vertical emery roller 132. After the dried material enters the emery chamber, the rice milling motor 131 is activated, driving the vertical emery roller 132 to rotate, causing friction on the material to remove rice husks from the surface. The rice husks are then drawn through the rice milling screen 133 into the impurity removal air box 250.

[0028] Please refer to Figure 3 and Figure 4 The impurity removal air box 250 includes an air suction flare 251, a ventilation duct 252, a fan 253, and an impurity removal duct 254. The air suction flare 251 is evenly and symmetrically located on both sides of the rice milling housing 110. One end of the ventilation duct 252 is fixedly connected to the air suction flare 251, and the other end of the ventilation duct 252 is fixedly connected to the fan 253. The impurity removal duct 254 is fixedly connected to the fan 253. During the rice milling process, the fan 253 is started to enhance the ventilation effect of the rice milling sand roller 130, so that bran powder is sucked into the air suction flare 251, passes through the ventilation duct 252, and is discharged out of the device through the impurity removal duct 254.

[0029] In summary, the working principle of a vertical sand roller rice whitening machine according to an embodiment of the present invention is as follows: when in use, the material is poured into the drying box 210, the stirring motor 221 is started, the rotating shaft 222 is driven to rotate, and the stirring roller 223 is rotated, so that the material is stirred, so that the material is fully stirred in the drying box 210, and the material is evenly dried by the heating plate 230 until it reaches the qualified moisture content, the solenoid valve 240 is opened, and the material falls into the rice milling box 110, and the tilting angle 121 guides the material to the installation screen plate 122 respectively, and the material enters the rice milling room through the installation screen plate 122, and the rice milling motor 131 is started to drive the vertical sand roller 132 to rotate, so that the material is rubbed, thereby removing the rice skin on the surface, and the rice skin forms chaff. Powder, then start the fan 253 to enhance the ventilation effect of the whitening chamber. The bran powder is screened by the rice milling screen 133 and is sucked into the air suction expansion port 251. The bran powder passes through the ventilation duct 252 and is discharged out of the device through the impurity discharge duct 254, so that most of the bran powder can be discharged in time, so that the whitening chamber is not easily blocked. The material is dried in time in the drying box 210, so that the material is not easily adhered, and the rice milling effect is not affected. The whitening chamber is not easily blocked by the impurity cleaning air box 250, which solves the problem in the prior art that when the material is relatively moist and the moisture content does not meet the standard, the connection between rice and husk, and between rice and rice is relatively tight, which is prone to adhesion. It also solves the problem in the prior art that the whitening chamber is easily blocked, thereby affecting the rice milling effect.
