Abstract
Description
Technical Field
[0001] This application relates to the field of screening technology, specifically a screening device for glutinous rice flour processing. Background Technology
[0002] During the planting, harvesting, transportation and storage of glutinous rice, impurities such as rice husks, sand, and metal fragments may be mixed in. These impurities not only affect the sensory quality of glutinous rice flour (such as color and taste), but may also carry microorganisms or harmful substances, posing a potential threat to consumers' health. In order to remove impurities such as rice husks, sand, and metal fragments mixed in with glutinous rice flour, screening equipment is generally used in the production process of glutinous rice flour.
[0003] For example, patent CN220658316U discloses a sieving device for water-milled glutinous rice flour. This patent achieves the effect of sieving glutinous rice flour by setting a sieve plate with a certain mesh size, so as to remove impurities such as rice husks, sand, and metal fragments mixed in with the glutinous rice flour.
[0004] During the sieving process of glutinous rice flour, because glutinous rice flour is rich in starch and protein, it easily absorbs moisture from the environment, causing liquid bridges to form between particles and agglomerate. However, the clumps may clog the screen, thereby reducing the actual sieving area and the throughput.
[0005] Therefore, it is necessary to provide a sieving device for glutinous rice flour processing to solve the above problems.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0019] like Figures 1-2 As shown, this application provides a sieving device for glutinous rice flour processing. The sieving device is usually installed on a glutinous rice flour processing production line and is mainly used for the sieving process in the refining of glutinous rice flour. Specifically, the sieving device includes a support 1 fixedly installed on the glutinous rice flour processing production line and a sieving mechanism 2 fixedly installed on the upper end of the support 1. The sieving mechanism 2 is used to sieving glutinous rice flour. The screening mechanism 2 includes fixed seats 20 fixed at both ends of the support 1, and a rotating shaft 24 is rotatably arranged between the fixed seats 20. At the same time, a first motor 23 is fixedly arranged at one end of the support 1. The output end of the first motor 23 is fixedly connected to the rotating shaft 24, so that starting the first motor 23 can drive the rotating shaft 24 to rotate between the fixed seats 20. Meanwhile, a fixing rod 25 is fixedly installed on the outside of the rotating shaft 24, and a sieve cylinder 21 is fixedly installed on the other end of the fixing rod 25. The sieve cylinder 21 has multiple sets of sieve holes, so that the first motor 23 can be started to drive the sieve cylinder 21 to rotate between the fixed seats 20 through the rotating shaft 24, so as to facilitate the subsequent sieving of glutinous rice flour. It should be noted that there is a height difference between the fixed seats 20 at both ends of the bracket 1, which causes the rotating shaft 24 between the fixed seats 20 to be in an inclined state, so that the screen cylinder 21 is also set at an inclination, and the screen cylinder 21 is inclined downward along the direction away from the first motor 23. In order to guide glutinous rice flour into the sieve cylinder 21, a fixing frame 28 is fixedly installed on the support 1 near the first motor 23. The fixing frame 28 is provided with an inlet channel 29. The inlet channel 29 has an inlet end that extends into the inside of the sieve cylinder 21 and is located at the higher end of the sieve cylinder 21. Thus, glutinous rice flour can be guided into the higher end of the sieve cylinder 21 through the inlet channel 29. As the sieve cylinder 21 rotates, the glutinous rice flour will slowly move to the lower end of the sieve cylinder 21. During the movement of the glutinous rice flour, the glutinous rice flour that meets the requirements will pass through the sieve holes of the sieve cylinder 21, while the impurities mixed in the glutinous rice flour will remain inside the sieve cylinder 21 and be discharged from the lower end of the sieve cylinder 21. In order to collect glutinous rice flour and impurities, a receiving pipe 26 is fixedly installed at the lower end of the support 1. The receiving pipe 26 is located at the lower end of the sieve hole so that the sifted glutinous rice flour will fall freely into the receiving pipe 26 for collection. In addition, an outlet pipe 27 is fixedly installed at the lower end of the support 1. The outlet pipe 27 is located at the end of the sieve cylinder 21 so that impurities discharged from the lower end of the sieve cylinder 21 will enter the outlet pipe 27 for collection. To prevent glutinous rice flour from clumping together during the sieving process, such as Figures 1-4 As shown, a dispersing mechanism 3 is provided on the inlet channel 29. The dispersing mechanism 3 performs a pre-dispersing operation on the processed glutinous rice flour to prevent the glutinous rice flour from clumping together. The dispersing mechanism 3 includes a second motor 31 fixedly installed on the outside of the inlet channel 29. A rotating rod 32 is fixedly installed on the output end of the second motor 31. The rotating rod 32 extends into the interior of the inlet channel 29, thereby activating the second motor 31 to drive the rotating rod 32 to rotate inside the inlet channel 29. Meanwhile, a dispersing blade 33 is fixedly installed on the outside of the rotating rod 32, and the dispersing blade 33 covers the inside of the inlet channel 29 so as to disperse the glutinous rice flour. At the same time, an inlet 30 is fixedly installed on the inlet channel 29 at the upper end of the dispersing blade 33. The inlet 30 is connected to the inside of the inlet channel 29, so that the glutinous rice flour to be sieved can be introduced into the inlet channel 29 through the inlet 30. Then, the dispersing blade 33 disperses the glutinous rice flour. After dispersing, it is introduced into the sieve cylinder 21 through the inlet channel 29 for subsequent sieving. In order to further prevent the glutinous rice flour from clumping, a ventilation duct 34 is fixedly installed at the upper end of the inlet channel 29. The ventilation duct 34 is connected to the inside of the inlet channel 29 so that external air can be introduced into the inside of the inlet channel 29 for subsequent drying of the glutinous rice flour inside the inlet channel 29. In order to dry the glutinous rice flour, an electric heating wire 35 is fixedly installed inside the ventilation duct 34. The electric heating wire 35 provides a heat source for drying the glutinous rice flour. A fan 36 is fixedly installed at the upper end of the ventilation duct 34. The fan 36 is used to blow the heat source provided by the electric heating wire 35 into the inlet channel 29, thereby achieving the effect of drying the glutinous rice flour inside the inlet channel 29. Before the sieving operation, the glutinous rice flour to be sieved can first be introduced into the inlet channel 29 through the inlet 30. Then, the heating wire 35 is turned on to provide a heat source. Then, the fan 36 is turned on to blow the heat source of the heating wire 35 onto the glutinous rice flour inside, thereby performing a preliminary drying operation. At the same time, the glutinous rice flour will move along the inlet channel 29 to the dispersing blade 33. Then, the second motor 31 is turned on to start the dispersing blade 33 to disperse the glutinous rice flour to be sieved. Finally, it is introduced into the sieve cylinder 21 through the inlet channel 29 for sieving, thereby achieving the effect of avoiding clumping before sieving.
[0020] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
