Description

Technical Field

[0001] The utility model relates to the technical field of flour detection, in particular to a flour coarseness and fineness detector. Background Art

[0002] The coarseness of flour reflects the processing precision of flour. The finer the flour, the lower the precision. The coarser the flour. The coarser the flour, the smaller the contact area with water when preparing dough, which reduces the water penetration rate and prolongs the gluten formation time. The protein of over-grinded flour is partially denatured, the water absorption rate decreases, and the dough is not elastic enough. The damaged starch will also absorb water quickly and in large amounts, and have a strong swelling effect. If there is not enough gluten to wrap the starch, the dough will also appear to be inelastic. At the same time, because the damaged starch absorbs a large amount of water quickly, the normal water distribution ratio in the dough is unbalanced, the protein absorbs insufficient water, and cannot form enough wet gluten. Therefore, the proportion of damaged starch should be controlled.

[0003] At present, the analysis of the coarseness and fineness of flour is generally carried out manually using different screening instruments to first sort the flour, and then take photos of the flours of different particle sizes, magnify them for detection, and analyze them. Since there is no systematic detection and analysis equipment, this link is not efficient, and since it is implemented in multiple steps, it requires a lot of manual input and is prone to errors.

[0004] Based on this, it is necessary to develop a systematic flour coarseness detector. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example: Figure 1 As shown, the flour coarseness detector of this embodiment includes a base 1, a multi-stage vibrating screening component 2, an electron microscope group 3 and a main machine, the multi-stage vibrating screening component 2 is installed on the upper end of the base 1, the multi-stage vibrating screening component 2 has a plurality of material outlets 211 for discharging materials of different particle sizes after screening, a weighing area is provided on the base 1, a plurality of electronic weighing devices 4 corresponding to the material outlets 211 are arranged at intervals in the weighing area, a material receiving box 41 is provided on the electronic weighing device 4, each of the material outlets 211 is connected to a discharge channel 212 extending to the corresponding material receiving box 41, the electron microscope group 3 is installed on the base 1, and the electron microscope group 3 and the electronic weighing device 4 are respectively connected to the main machine.

[0025] The usage process is as follows:

[0026] Put the flour raw material into the multi-stage vibration screening component 2, and screen it through the multi-stage vibration screening component 2 to obtain flour materials of different levels and different particle sizes (particles), and each level of flour will fall into the material receiving box 41 through the material outlet 211, and be weighed by the corresponding electronic weighing device 4. After weighing, the material receiving box 41 is microscopically observed at the electron microscope group 3 in the detection area of ​​the machine base 1, and photographed. The above weighing information and the photographic information under the microscope are uploaded to the host for analysis and storage, and finally the relevant information of the coarseness of the flour is obtained. The whole process only needs to add the flour raw material, and then take the material receiving box 41 for detection. The whole machine structure design is simple and reasonable, which can realize the multi-level particle sorting of flour, and can weigh and microscopically observe and analyze each level of particles. The whole process has high operating efficiency, standardized process, and relatively accurate detection and analysis results.

[0027] In this embodiment, the host adopts a compatible model on the market and is equipped with a display A. The display A is set in a conspicuous position on the side surface of the base 1, preferably at the position where the electron microscope group 3 is located, so that the inspection personnel can observe the data information.

[0028] As a preferred embodiment, Figure 2 As shown, the multi-stage vibration screening assembly 2 includes a vibrator 21, a plurality of sieve plates 22 with open tops, and a top cover 23. The plurality of sieve plates 22 are stacked from bottom to top and installed on the upper end of the vibrator 21. The top cover 23 covers the upper end of the uppermost sieve plate 22. A feed port (indicated by b in the figure) is provided on the top cover 23. The side walls of the sieve plates 22 are respectively provided with the material outlets 211. The bottom walls of all the sieve plates 22 except the lowest one are provided with a sieve-like bottom wall, and the mesh size of the sieve gradually decreases from top to bottom. The vibrator 21 is connected to the main machine.

[0029] In the above embodiment, after the flour raw material is put into the topmost sieve plate 22 through the feed port on the top cover 23, the vibrator 21 is started to generate vibration force, and the flour raw material is screened from top to bottom through the mesh holes of the bottom wall of the sieve plate 22 layer by layer under the action of vibration, and particles smaller than the mesh size fall into the next sieve plate 22 layer by layer, and finally multiple levels of flour materials with different particle sizes appear in the sieve plate 22, and the flour materials in each sieve plate 22 are all discharged from the material outlet 211 (the lower edge of the material outlet 211 is flush with the inner bottom wall of the sieve plate 22) under the action of vibration, and fall into the corresponding material receiving box 41 on the electronic weighing device 4 through the discharge channel 212 for weighing, and the operator then transfers the weighed material receiving box 41 to the electron microscope group 3 for microscopic observation. The entire structural design is reasonable, which simplifies the entire detection process and has a compact structural layout.

[0030] In this embodiment, the discharge channel 212 is a channel with one end extending horizontally or obliquely downward, and a downward vertical material drop section is set at the end of the discharge channel 212 away from the sieve plate 22. The vertical material drop section just docks with the receiving box 41 below to achieve good material drop.

[0031] It should be noted that in this embodiment, the sieve plate 22 is a cylindrical shell structure with an open upper end, and the bottom wall is covered with mesh holes.

[0032] In this embodiment, the electron microscope group 3 can be any product of suitable model on the market, which belongs to the prior art product and will not be described in detail here.

[0033] As a preferred embodiment, an anti-blocking structure 5 is provided in the sieve plate 22 .

[0034] In the above embodiment, since the flour in the sieve plate 22 falls through the mesh holes on the bottom wall, the mesh holes may be blocked by the flour. Therefore, by adding an anti-blocking structure 5, the mesh blockage phenomenon can be improved to ensure good screening of the multi-stage vibrating screening assembly 2.

[0035] As a preferred embodiment, Figure 2As shown, the anti-blocking structure 5 includes a rotating shaft 51 and a plurality of scraping blades 52. The rotating shaft 51 vertically penetrates the middle of all the sieve plates 22 except the lowest one and the middle of the top cover 23. The rotating shaft 51 is rotationally connected with the sieve plates 22 and the top cover 23. The plurality of scraping blades 52 are respectively mounted on the rotating shaft 51 and are distributed one by one on the inner bottom walls of all the sieve plates 22 except the lowest one. A rotating driving device 53 is provided at the upper end of the top cover 23, and the rotating driving device 53 is transmission-connected with the upper end of the rotating shaft 51.

[0036] In the above embodiment, when the mesh is clogged, or during the screening process, the rotary drive device 53 is started regularly to drive the rotating shaft 51 and the scraper blade 52 to rotate. During the rotation, the scraper blade 52 contacts the bottom wall of the sieve plate 22 and scrapes, which can effectively improve the mesh clogging phenomenon.

[0037] In this embodiment, the rotating shaft 51 is rotatably connected to the through hole passing through the middle of the sieve plate 22 via a bearing (or a sleeve).

[0038] In this embodiment, the rotation driving device 53 is a motor, and is connected to the host, and the start and stop of the motor and the power are controlled by the host.

[0039] In this embodiment, the material outlets 211 of the plurality of sieve plates 22 are spaced apart in the circumferential direction. This design facilitates the good arrangement of the plurality of electronic weighing devices 4 on a plane and avoids interference in positions.

[0040] As a preferred embodiment, the weighing area is equipped with a stepped bracket 6, and each step surface of the bracket 6 is respectively equipped with the electronic weighing device 4, and the discharge channels 212 connected to the multiple material outlets 211 respectively extend one by one to the top of the multiple material receiving boxes 41.

[0041] In the above implementation scheme, the design of the stepped bracket 6 is relatively clever. Since the multiple sieve trays 22 are stacked up and down, their heights are not the same. Therefore, each step surface of the stepped bracket 6 also corresponds to a different height. Specifically, the electronic weighing device 4 and the receiving box 41 on the topmost step surface are used to connect with the discharge channel 212 of the topmost sieve tray 22, and the remaining discharge channels 212 connected to each layer of sieve trays 22 from top to bottom correspond to the electronic weighing device 4 and the receiving box 41 on each remaining step surface layer by layer (the height decreases layer by layer), and the arrangement is relatively reasonable.

[0042] In this embodiment, a feed hopper is connected to the upper end of the feed port, and flour raw materials can be conveniently added to the sieve plate 22 through the feed hopper.

[0043] In this embodiment, a shock absorbing pad is provided at the bottom of the base 1. The shock absorbing pad can reduce the vibration transmission effect of the vibration on the table, the ground and other carriers, and reduce the noise to a certain extent.

[0044] In this embodiment, handrails for convenient carrying are provided on opposite sides of the base 1. The whole device can be conveniently lifted and carried by the handrails on both sides.
