After weighing, the corresponding flours are fed into the blending mixer for mixing to obtain the corresponding flour. However, if Figure 1 and Figure 2 As shown, a single silo 1' in the powder mixing processing system in the prior art is usually connected to a single powder mixing scale 3', resulting in that the single silo 1' can only transport powder to the single powder mixing scale 3'. When the same kind of powder requires two or more powder mixing scales 3' with different measuring ranges to be weighed, a corresponding number of silos 1' can only be set up to match the powder mixing scales 3' with different measuring ranges, which not only increases the space occupied by the powder mixing processing system, but also increases the manufacturing cost of the system.

DETAILED DESCRIPTION

[0031] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. While the following embodiments illustrate a wheat flour blending and processing system, the solution is also applicable to blending and processing systems for other cereals and plant-based powders, such as rice flour, buckwheat flour, and millet flour.

[0032] It should be noted that, in the description of the present invention, terms such as "upper", "lower", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance.

[0034] The wheat flour blending system in the prior art is equipped with multiple silos to store flours of different qualities or characteristics. During the blending process, the flours in different silos are transported to the corresponding blending scales for weighing. After weighing, the corresponding flours are fed into the blending mixer for mixing to obtain the corresponding flour. However, if Figure 1 and Figure 2As shown, a single silo 1' in the powder mixing processing system in the prior art is usually connected to a single powder mixing scale 3', resulting in that the single silo 1' can only transport powder to the single powder mixing scale 3'. When the same kind of powder requires two or more powder mixing scales 3' with different measuring ranges to be weighed, a corresponding number of silos 1' can only be set up to match the powder mixing scales 3' with different measuring ranges, which not only increases the space occupied by the powder mixing processing system, but also increases the manufacturing cost of the system.

[0035] In order to solve the problem in the above-mentioned prior art that a single silo 1' of the powder mixing processing system can only transport powder to a single powder mixing scale 3', thereby increasing the occupied space and manufacturing cost of the powder mixing processing system, an embodiment of the present utility model provides a powder mixing processing system for powder, which includes a silo, at least two screw conveyors and at least two powder mixing scales.

[0036] The interior of the silo is used to store powder, the discharge port of the silo is located below it, and a vibrating discharger is provided at the discharge port to promote the flow and transportation of powder.

[0037] At least two screw conveyors are arranged in sequence along a vertical direction. The feed port of the screw conveyor located vertically uppermost among the at least two screw conveyors is connected to the discharge port of the silo. Two vertically adjacent screw conveyors are connected via an on-off valve. When the on-off valve is open, powder can be transferred from the upper screw conveyor to the lower screw conveyor through the on-off valve. The feed port of the powder mixing scale is connected to the discharge port of the screw conveyor in a one-to-one correspondence. Specifically, the screw conveyor is a circular tube auger, and the on-off valve is a two-way valve.

[0038] Furthermore, of the two screw conveyors adjacent to each other in the vertical direction, the discharge port of the upper screw conveyor is communicated with the feed port of the lower screw conveyor through an on-off valve.

[0039] Furthermore, the feed port of the screw conveyor and the discharge port thereof are arranged correspondingly in the vertical direction.

[0040] like Figure 3 As shown, the on-off valve 5 includes a valve body 51, a telescopic driving component 52 and a valve plate component 53. The valve body 51 has a powder channel inside that is connected to the screw conveyor above and the screw conveyor below. The valve body 51 is provided with a telescopic driving component 52 on its radial side. The telescopic end of the telescopic driving component 52 is connected to the valve plate component 53 so that it can drive the valve plate component 53 to move back and forth, thereby being able to control the opening and closing state of the on-off valve 5 by controlling the opening and closing state of the powder channel in the valve body 51.

[0041] Specifically, continue to refer to Figure 3The telescopic drive component 52 is specifically a cylinder drive device, which has an air valve 521. The air valve 521 is electrically connected to the PLC module 54. The PLC module 54 controls the telescopic state of the cylinder drive device by controlling the air valve 521. When the cylinder drive device is in the extended state, the valve plate component 53 can close the powder channel in the valve body 51, preventing the powder from transferring from the feeding port of the screw conveyor to the screw conveyor below the screw conveyor. When the cylinder drive device is in the retracted state, the valve plate component 53 does not close the powder channel in the valve body 51, allowing the powder to be transferred from the feeding port of the screw conveyor to the screw conveyor below the screw conveyor.

[0042] The flour mixing system also includes at least one flour mixing mixer, the feed inlet of which is connected to the discharge outlet of a corresponding flour mixing scale. It should be noted that flour products are typically made by mixing powders of different qualities or characteristics in a specific ratio. A single flour product is typically equipped with a single flour mixing mixer.

[0043] Furthermore, the discharge ports of the at least two powder mixing scales are respectively connected to the same powder mixing mixer. With the above arrangement, when mixing and processing a flour product, the powder in a single silo can be transported to the same powder mixing mixer via the at least two powder mixing scales for mixing.

[0044] Furthermore, each of the at least two powder mixing scales has a different measuring range. A powder mixing scale with a suitable measuring range is selected according to actual product conditions.

[0045] In some specific embodiments, the discharge port of each of the at least two flour mixing scales is connected to a different flour mixing mixer. With this arrangement, when mixing flour to produce different flour products, the powder in a single silo can be transported by the at least two flour mixing scales to the corresponding flour mixing mixer for mixing.

[0046] When the above technical solution is adopted, the embodiment of the present invention can connect two screw conveyors adjacent in the vertical direction by setting an on-off valve 5, so that the same silo can convey powder to the corresponding powder mixing scale through the corresponding screw conveyor. Compared with the solution in the prior art, the single silo of the embodiment of the present invention can convey powder to at least two powder mixing scales, so that there is no need to add additional silos according to the number of powder mixing scales, which not only reduces the space occupied by the powder mixing processing system, but also reduces the manufacturing cost of the system. At the same time, it can also eliminate the turnover consumption of the same powder between different silos in the prior art, reduce production energy consumption, and achieve a large-scale proportion of powder matching, effectively solving the flexible switching of powder matching ratios from 10% to 100%. In addition, through the above-mentioned setting, the single silo of the embodiment of the present invention can convey powder to powder mixing scales in different positions, which can save production time and improve the response speed and production efficiency of flour processing.

At this time, the powder in the first silo 11 is transported to the second powder mixing scale 32 through the second screw conveyor 22. It should be noted that the on-off valve 5 is started and stopped synchronously with the first screw conveyor 21 and the second screw conveyor 22, respectively, to avoid the risk of powder blockage and powder cross-contamination in the screw conveyors.

[0053] When the above technical solution is adopted, in the embodiment of the utility model, when mixing flour products, the powder in the first silo 11 can be conveyed to the first mixing mixer 41 for mixing through the first screw conveyor 21 and the first mixing scale 31, and can also be conveyed to the first mixing mixer 41 for mixing through the second screw conveyor 22 and the second mixing scale 32.
