technical field

The invention relates to the field of food processing, in particular to a polishing device for rice processing.

Background technique

The general working process of the rice polishing machine is as follows: the white rice that has been whitened by the rice mill to reach the precision of one meter flows down from the feeding port into the polishing chamber, and the heated (used when the room temperature is lower than 15°C) is heated by the temperature-controlled water tank. Water passes through the flow meter, flows through the rubber tube to the air-water mixing nozzle, and then forms water mist through high-pressure air, and enters the water area of the hollow main shaft. Under the action of strong negative pressure suction, the water mist passes through the main shaft and the ventilation holes of the polishing roller. It enters the surface of the polishing roller and mixes with the rice, and adheres to the surface of the rice grains to moisten and soften the surface of the rice grains. Through the rotary motion of the polishing roller in the polishing chamber, the rice grains are constantly moving in the polishing chamber. During the movement, relative motion, relative friction and extrusion are generated between the rice grains, between the rice grains and the polishing roller, and between the rice grains and the rice sieve. Since the surface of the rice grain is moistened and softened, this friction will remove the bran powder and acne on the surface of the rice grain on the one hand. On the other hand, during the friction and extrusion process, the starch layer on the surface of white rice undergoes gelatinization and crystallization to form a bright protective film, which improves the surface finish and prolongs the storage time of later rice.

When in use, the polishing device for rice processing is first installed in the rice processing workshop, the power supply in the workshop is connected, and the drinking water source is connected to the water injection pipe 103 through the water pipe, and after pouring a sufficient amount of reference water into the water tank 101, the Open the water pipe, cover the cap on the water injection pipe 103 again, and then control and start the drive assembly 102, the drive assembly 102 will pump the water in the water tank 101 out, and pump it to the Y-shaped pipe 105, and then pass through two atomizers 106 to Drinking water is atomized and sprayed into the water pipe 6, so that water mist is permeated in the water pipe 6, and then the rice whitened by the rice mill is transferred to the two water pipes 6 by the elevator, and when the rice grains pass through the water pipe 6, The rice grains are in full contact with the water mist, so that the surface of the rice grains is fully covered with water.

The rice grains after watering enter the feeding pipe 5 from the water pipe 6, drop on the left part of the polishing roller 202, and simultaneously control and start two first power assemblies 201 and a second power assembly 207, the first power assembly 201 and a second power assembly 207 The rotation directions of the two power assemblies 207 are opposite, wherein the output shaft of the first power assembly 201 rotates, synchronously drives the polishing roller 202 to rotate, and the output shaft of the second power assembly 207 rotates, synchronously drives the two screens 206 to rotate, so that the polishing roller 202 and the sieve The direction of rotation of the net 206 is opposite. When the polishing roller 202 rotated, the arc-shaped ribs 20201 pushed the rice grains to the right. Relative movement, relative friction and extrusion are produced between the rollers 202 and between the rice grains and the screen 206. Because the surface of the rice grains is wet, the friction and extrusion will remove the bran powder and form a bright protective film on the surface of the rice grains. The rotation direction of the net 206 is opposite, so that the polishing of the rice grains is more sufficient, the polishing efficiency of the rice is improved, and the heat generated by the polishing of the rice is helped to dissipate.

Then the rice grains that have been polished are discharged from the discharge pipe 2010 to the sorting cabin 203. Because polishing needs to squeeze and rub the rice grains, it is easy to produce broken rice. When the polished rice grains fall in the sorting cabin 203, the rice grains and the bottom contact with the second elastic member 304, at this moment, the rice grains will be bounced off by the second elastic member 304. Since the mass of the intact rice grains is larger than that of the broken rice, the inertia of the intact rice grains is larger, and the inertia of the broken rice is smaller, so the integrity After the grains of rice touch the second elastic member 304, the momentum is larger, and the rebound distance of the intact rice grains is longer, while the momentum of the broken rice is smaller, and the rebound distance of the broken rice is shorter, so the intact rice grains can pass through the through groove 20303 and enter the collection tank 20304, then the complete rice grains are exported from the first Y-shaped guide pipe 301 to enter the downward processing step, and the broken rice cannot cross the channel 20303, but can only continue to fall along the sorting cabin 203 and then from the second Y-shaped The guide tube 302 leads out, wherein when the rice grains in the first Y-shaped guide tube 301 are sampled, according to the amount of broken rice therein, the user will manually turn the knob 401 after pulling out the pin 403 to adjust the rotation. The angle of the board 303, and then control the angle of the bouncing of rice grains, reduce the broken rice into the collection tank 20304, and then insert the pin 403 into a pin hole 20301 nearby, and block the hanging plate 402 through the pin 403, wherein when the user holds When being stained with rice flour or bran powder, in order to avoid skidding when grabbing the knob 401, several anti-skid grooves are provided at this time, which increases the contact friction between the user's hand and the knob 401, and facilitates the steering control of the rotary plate 303. Helps to better control the quality and commercial value of rice products.

Wherein when the rice grain is polished, the bran powder produced is generally discharged through the screen 206, and the bran powder is polished after the rice grain is moistened simultaneously, so the bran powder is also in a wet state, and the bran powder will adhere to the screen cloth 206, and Because the rice polishing process generates a lot of heat, the water on the rice grains and bran powder will be evaporated, so the outer surface of the bran powder on the screen 206 is dry, and the inside is a wet state, which seriously affects the heat dissipation of the screen 206. At this time, the third power assembly 501 is controlled and started, and the output shaft of the third power assembly 501 rotates, which synchronously drives the two cleaning parts 504 to move away from each other. Since the cleaning parts 504 move horizontally and the screen 206 rotates, The bristles on the cleaning part 504 sweep away the bran powder on the screen cloth 206, and the cleaning part 504 also presses the reset part 505 when moving simultaneously, so that the reset part 505 is deformed. When the rack 506 is engaged, the two reset parts 505 are restored, and the reset part 505 not only resets the cleaning part 504 quickly, so that the cleaning part 504 is swept away from the screen cloth 206 quickly, and when reset by the reset part 505, the cleaning part 504 has a slant. Upward thrust makes cleaning part 504 when sliding over slide bar 503, and cleaning part 504 has pressure on slide bar 503, and cleaning part 504 moves on slide bar 503, and cleaning part 504 scrapes the bran powder on slide bar 503 In addition, the heat generated by the friction between the cleaning member 504 and the slide bar 503 is dissipated through the cooperation of the hollow slide bar 503 and the star-shaped grooves on the polishing chamber 2 .

After the polishing device has been in operation for a period of time, there will be bran powder adhered on the screen cloth 206 and it is difficult to remove by the cleaning member 504. At this time, the screen cloth 206 needs to be taken off regularly, cleaned or replaced, to avoid the difficult-to-remove chaff powder, Bacteria will grow and affect the hygiene of the rice. At this time, the user only needs to open the movable cover 3 upwards by holding the handle 4, and then manually press the annular plate 205. The annular plate 205 moves to the left, and the first elastic member 204 is pressed. Compress, and then pull the screen 206 to the right, the screen 206 is deformed and withdraws from the clipping position of the feeding pipe 5, and then, the right part of the screen 206 is pulled out from the clipping position of the discharge pipe 2010, and wait After the screen 206 has been cleaned or replaced, the screen 206 is now inserted into the clamping position of the discharge pipe 2010, and then the screen 206 is deformed and pushed into the clamping position of the feeding pipe 5, and then the annular plate 205 is loosened. Open, after the first elastic member 204 recovers, circle the annular plate 205 outside the screen cloth 206, fix the screen cloth 206, after the screen cloth 206 is reinstalled, fasten the movable cover 3 again.
