Description

Technical Field

[0001] This utility model relates to the technical field of rice sieving devices, specifically an improved rice processing rice sieving device. Background Technology

[0002] In the rice processing process, removing the bran is an important step. Good bran removal can improve the quality of rice and meet the market demand for high-quality rice.

[0003] Traditional rice bran screening devices typically perform centralized screening after the rice has undergone preliminary processing. Because a significant amount of bran remains in the rice during screening, the process is relatively time-consuming and unsuitable for large-scale rice processing. When processing large quantities of rice, multiple screening operations may be required, consuming substantial time and energy. Therefore, we propose an improved rice processing bran screening device. Utility Model Content

[0004] The purpose of this invention is to provide an improved rice processing sifting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved rice processing sieving device, comprising a base plate, a support rod installed on the top surface of the base plate, a sieve cylinder installed at the upper end of the support rod, a vibration motor installed on the outside of the sieve cylinder, multiple connecting rods installed on the outside of the sieve cylinder, a discharge cylinder installed between the multiple connecting rods, two fixed rods installed in the inner cavity of the discharge cylinder, and a baffle block installed between the two fixed rods;

[0006] A fixed cylinder is installed on the bottom surface of the baffle block, and multiple air outlet holes are opened on the outer side of the fixed cylinder. An air outlet assembly for supplying air into the fixed cylinder is installed on the top surface of the base plate.

[0007] Preferably, a feed hopper is fixedly installed at the upper end of the discharge cylinder.

[0008] Preferably, the stop block is conical in shape.

[0009] Preferably, the upper part of the baffle block passes through the discharge cylinder, and there is a gap between the outer wall of the baffle block and the discharge cylinder.

[0010] Preferably, the air outlets are distributed in a ring at equal intervals on the outside of the fixed cylinder.

[0011] Preferably, the air outlet assembly includes a fan, the air outlet of the fan is connected to an air duct, and the upper end of the air duct is connected to the bottom of the fixed cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This improved rice processing bran screening device, when the blower is turned on, air enters the fixed cylinder through the air duct and is blown out through the air outlet. At this time, rice is added into the feed hopper, and the rice in the feed hopper enters the discharge cylinder and continues to fall. Under the action of the baffle block, the rice slides outward along the inner wall of the baffle block. The baffle block has the effect of dispersing the rice and sliding it outward. The air blown out of the air outlet can blow some of the rice bran in the rice to the outside of the screening cylinder, so that some rice bran will not fall into the screening cylinder with the rice. During the falling process, the amount of rice bran mixed in with the rice is reduced, the subsequent screening pressure is reduced, and the overall screening efficiency is improved.

[0014] 2. In this improved rice processing bran sieving device, after the rice falls into the sieve cylinder, the vibration of the sieve cylinder causes the residual bran in the rice to be sieved away, thus completing the bran sieving work and improving the quality of the rice.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-4As shown, this utility model provides an improved rice processing sieving device, including a base plate 1, a support rod 2 installed on the top surface of the base plate 1, a sieve cylinder 3 installed at the upper end of the support rod 2, a vibration motor 4 installed on the outside of the sieve cylinder 3, multiple connecting rods 5 installed on the outside of the sieve cylinder 3, a discharge cylinder 6 installed between the multiple connecting rods 5, two fixing rods 8 installed in the inner cavity of the discharge cylinder 6, and a baffle block 9 installed between the two fixing rods 8;

[0023] A fixed cylinder 10 is installed on the bottom surface of the baffle block 9. Multiple air outlet holes 11 are opened on the outside of the fixed cylinder 10. An air outlet assembly for supplying air into the fixed cylinder 10 is installed on the top surface of the base plate 1.

[0024] Specifically, before the rice falls into the sieve cylinder 3 through the discharge cylinder 6, the air outlet component is opened so that the fixed cylinder 10 can discharge air through the air outlet 11, blowing the bran in the rice outward so that some of the rice bran will not fall into the sieve cylinder 3. This reduces the amount of bran mixed in with the rice before sieving.

[0025] Among them, the upper end of the discharge cylinder 6 is fixedly installed with a feeding hopper 7, which facilitates the conveying of rice into the discharge cylinder 6.

[0026] Among them, the baffle block 9 is conical, the upper part of the baffle block 9 passes through the discharge cylinder 6, and there is a gap between the outer wall of the baffle block 9 and the discharge cylinder 6. The rice passing through the discharge cylinder 6 can tilt and fall outward under the guidance of the surface of the baffle block 9.

[0027] Wherein: the air outlet 11 is distributed in a ring at equal intervals on the outside of the fixed cylinder 10. The air outlet assembly includes a fan 12. The air outlet of the fan 12 is connected to an air duct 13. The upper end of the air duct 13 is connected to the bottom of the fixed cylinder 10. When the fan 12 is turned on, the air enters the interior of the fixed cylinder 10 from the air duct 13 and is blown out through the air outlet 11.

[0028] Working principle: This utility model is an improved rice processing bran sieving device. When in use, the switch of the vibration motor 4 is turned on, causing the screen cylinder 3 to vibrate. The switch of the blower 12 is turned on, and the air enters the fixed cylinder 10 from the air pipe 13 and is blown out through the air outlet 11. At this time, rice is added into the feed hopper 7. The rice in the feed hopper 7 enters the discharge cylinder 6 and continues to fall. Under the action of the baffle block 9, the rice slides outward along the inner wall of the baffle block 9. The baffle block 9 has the effect of dispersing the rice and sliding it outward. The air blown out of the air outlet 11 can blow some of the rice bran in the rice to the outside of the screen cylinder 3, so that some rice bran will not fall into the screen cylinder 3 with the rice.

[0029] After the rice falls into the sieve cylinder 3, the vibration of the sieve cylinder 3 causes the residual rice bran in the rice to be sieved away, thus completing the bran sieving work and improving the quality of the rice.
