Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bread production equipment, in particular to an automatic and uniform flour sprinkling device for bread. Background Technique
[0002] During the bread production process, the dough needs to be rounded for shaping. Since the dough has high viscosity, it is easy to stick to the rounding tool during rounding, resulting in difficult shaping of the dough.
[0003] Therefore, a layer of flour needs to be sprinkled on the surface of the dough before rounding. In the automatic bread production process, relying on manual flour sprinkling not only has a high labor intensity, but also the flour is not evenly sprinkled. Thus, the flour will be first installed in the storage bin. The bottom of the storage bin is provided with a discharge hole, and a vibrator is installed on the side wall of the storage bin, so that the flour falls from the discharge hole and is sprinkled on the dough.
[0004] However, since the flour is easy to accumulate into blocks, the phenomenon of blockage of the discharge hole is still likely to occur, resulting in uneven falling of the flour. Content of the Utility Model
[0005] In order to solve the technical problems in the background technique, the utility model discloses an automatic and uniform flour sprinkling device for bread.
[0006] The utility model provides an automatic and uniform flour sprinkling device for bread, including:
[0007] A flour hopper with flour installed inside;
[0008] A vacuum pump, whose inlet is connected to the outlet at the lower end of the flour hopper through a first pipeline;
[0009] A powder tank, whose inlet is connected to the outlet of the vacuum pump through a second pipeline; A third pipeline is also connected in parallel to the outlet of the vacuum pump. The third pipeline is communicated with the outside, and a filter is installed at its inlet;
[0010] A lower powder hopper, whose upper inlet is connected to the outlet at the lower end of the powder tank;
[0011] A powder rolling plate, which is arranged obliquely, with its high end located directly below the outlet at the lower end of the lower powder hopper and its low end located directly above the dough.
[0012] When the vacuum pump is started, the flour in the flour hopper is pumped into the powder tank. Since air will enter the second pipeline along the third pipeline when the vacuum pump is started, the powder tank contains a mixture of air and flour and falls into the lower powder hopper; Since air has a flow rate when the vacuum pump is started, the air in the lower powder hopper is mixed with the flour, increasing the gap between the flour particles, making the flour not easy to accumulate, and can smoothly flow out from the outlet of the lower powder hopper and be evenly distributed on the powder rolling plate; The utility model realizes automatic feeding of the dough, not only with high efficiency, but also with uniform powder sprinkling.
[0013] Since the flour at the outlet of the vacuum pump is likely to enter the third pipeline, which affects the normal powder spreading. Based on this, a further improvement is as follows: A connecting pipe is connected between the inlet of the second pipeline and the inlet of the third pipeline; A side pipe forming an acute angle is led out from the middle of the connecting pipe, and the inlet of the side pipe is close to the outlet of the third pipeline; The inlet of the side pipe is connected to the outlet of the first pipeline. With this setting, the part of the connecting pipe above the side pipe and the side pipe form an obtuse angle. When the flour flows out from the outlet of the first pipeline, under the impact force and the guiding effect of the part of the connecting pipe above the side pipe, it enters the second pipeline and will not enter the third pipeline.
[0014] Since when the flour slides off the powder rolling plate, part of it will fall into the area between the doughs, resulting in waste. Based on this, a further improvement is as follows: A material distributing plate is covered and installed directly below the outlet of the powder hopper; The material distributing plate is provided with multiple sunken sliding grooves; The upper end surface of the powder rolling plate is provided with multiple spaced partitions, and a sliding track is formed between every two adjacent partitions; The outlet of the sliding groove is directly above the inlet of the sliding track.
[0015] Since when the flour slides on the powder rolling plate, the speed is relatively fast and it is difficult to control the amount of falling material. Based on this, a further improvement is as follows: The partition is provided with two bends, and the opening directions of the two bends are opposite, including a middle plate and end plates led out from both ends of the middle plate; The end plates are parallel, and the end plates and the middle plate form an obtuse angle. With this setting, the sliding track forms two turns, which can reduce the sliding speed of the flour. The setting of the obtuse angle is used to reduce the sliding resistance of the flour and prevent the flour from piling up on the powder rolling plate.
[0016] Since the flour is likely to fall into the area outside the partition and drop to the ground, resulting in waste. Based on this, a further improvement is as follows: A material receiving groove is arranged below the powder rolling plate; Baffles extending upward are arranged on both sides of the material receiving groove; The inner side of the baffle is also connected to the side surface of the powder rolling plate, and the top of the baffle is higher than the partition; A residual material groove is formed between the baffle and the partition, and a material dropping hole is opened at the bottom of the residual material groove.
[0017] After the flour in the material receiving groove is stored to a certain amount, it needs to be taken out manually, and the operation is rather cumbersome. Based on this, a further improvement is as follows: A funnel is arranged at the lower end of the material receiving groove; The inlet of the funnel is communicated with the storage space of the material receiving groove, and the outlet is communicated with the third pipeline. With this setting, the flour in the material receiving groove will flow into the second pipeline along the third pipeline and enter the powder tank, realizing automatic recycling.
[0018] The flour in the powder hopper is likely to fall into the area connected to the sliding groove, thus reducing the utilization rate of the flour. Based on this, a further improvement is as follows: The outlet of the powder hopper is covered and connected with a mesh plate; The mesh plate is provided with multiple material dropping holes; The material dropping holes are distributed in multiple independent areas, each area corresponds to a sliding groove, and the sliding grooves cover the material dropping holes in the corresponding areas.
[0019] When the bread model changes and the size of the dough also changes, the amount of flour sprinkling needs to be adjusted. Based on this, a further design is that a horizontally arranged screen is also installed on the screen plate in a plug-in manner; the screen is located directly above the material discharging hole. In this way, the screen can be disassembled; when the size of the dough changes, the screen with different screen hole diameters can be replaced.
[0020] Furthermore, multiple spaced-apart insertion plates are also inserted at the upper end of the screen plate; the insertion plates are located above the screen and directly above the material discharging holes in the corresponding areas; the insertion plates are movable, and the outlet area of the flour hopper is changed by their movement.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.
[0032] As Figure 1 shown, the present utility model discloses an automatic and uniform flour sprinkling device for bread, which includes a vacuum feeding machine, a flour hopper 8 and a rolling flour plate 9.
[0033] The vacuum feeding machine includes a flour hopper 1, a powder tank 4 and a vacuum pump 2. Flour is contained in the flour hopper 1. The inlet of the vacuum pump 2 and the outlet at the lower end of the flour hopper 1 are connected through a first pipeline 3, and the outlet of the vacuum pump 2 and the inlet of the powder tank 4 are connected through a second pipeline 5. When the vacuum pump 2 is started, the flour in the flour hopper 1 can be pumped into the powder tank 4.
[0034] A third pipeline 6 is also connected in parallel to the outlet of the vacuum pump 2. The inlet of the third pipeline 6 is communicated with the outside, and a filter 7 is installed to filter impurities in the air.
[0035] As Figure 2 shown, a straight tubular connecting pipe 10 is connected between the inlet of the second pipeline 5 and the inlet of the third pipeline 6; a side pipe 11 forming an acute angle is led out from the middle of the connecting pipe 10, and the inlet of the side pipe 11 is close to the outlet of the third pipeline 6; the inlet of the side pipe 11 is connected to the outlet of the first pipeline 3. With such a setting, the part of the connecting pipe 10 above the side pipe 11 and the side pipe 11 form an obtuse angle. When the flour flows out from the outlet of the first pipeline 3, it enters the second pipeline 5 under the action of the impact force and the guiding action of the part of the connecting pipe 10 above the side pipe 11, and will not enter the third pipeline 6.
[0036] The outlet at the lower end of the powder tank 4 and the inlet at the upper end of the flour hopper 8 are connected. The upper part of the flour hopper 8 is frustum-shaped, and its cross-sectional area increases from top to bottom; the lower part of the flour hopper 8 is frustum-shaped, and its cross-sectional area decreases from top to bottom.
[0037] The rolling flour plate 9 is arranged obliquely, its high end is set directly below the outlet at the lower end of the flour hopper 8, and its low end is located directly above the dough.
[0038] A distributing plate 12 is covered and installed directly below the outlet of the flour hopper 8; the distributing plate 12 is provided with a plurality of concave sliding grooves 13; a plurality of spaced partitions 14 are arranged on the upper end surface of the rolling flour plate 9, and a slideway 15 is formed between every two adjacent partitions 14; the outlet of the sliding groove 13 is directly above the inlet of the slideway 15. The setting of the slideway 15 also makes the flour not fall into the area between the doughs and will not cause waste.
[0039] The partition plate 14 is provided with two bends, including a middle plate 141 and end plates 142 extending from both ends of the middle plate 141; the end plates 142 are parallel, and the end plates 142 and the middle plate 141 form an obtuse angle. With such a setting, the slideway 15 constitutes two turns, which can reduce the sliding speed of the flour. The setting of the obtuse angle is used to reduce the resistance of the flour sliding and prevent the flour from accumulating on the flour rolling plate 9.
[0040] As Figure 6 shown, a material receiving groove 16 is provided below the flour rolling plate 9; baffles 161 extending upward are provided on both sides of the material receiving groove 16; the inner sides of the baffles 161 are also connected to the side surface of the flour rolling plate 9, and the top of the baffle 161 is higher than the partition plate 14; a waste material groove 17 is formed between the baffle 161 and the partition plate 14, and a blanking hole 18 is opened at the bottom of the waste material groove 17. As Figure 4 and Figure 5 shown, a funnel 19 is provided at the lower end of the material receiving groove 16; the inlet of the funnel 19 is communicated with the storage space of the material receiving groove 16, and the outlet is communicated with the third pipeline 6. With such a setting, the flour in the material receiving groove 16 will enter the second pipeline 5 along the third pipeline 6 and enter the powder tank 4, realizing automatic recycling.
[0041] As Figure 3 shown, the outlet of the flour hopper 8 is covered and connected with a net plate 20; the net plate 20 is provided with a plurality of blanking holes 21; the blanking holes 21 are distributed in a plurality of independent areas, each area corresponds to a chute 13, and the chute 13 covers the blanking holes 21 in the corresponding area. In this way, the flour will not fall to the connection area of the chute 13.
[0042] As Figure 7 and Figure 8 shown, a horizontally arranged screen 22 is also installed on the net plate 20 by plugging; the screen 22 is located directly above the blanking hole 21. In this way, the screen 22 can be detached; when the size of the dough changes, the screen 22 with different sieve hole diameters can be replaced.
[0043] A plurality of spaced plug plates 23 are also plugged at the upper end of the net plate 20; the plug plates 23 are located above the screen 22 and directly above the blanking holes 21 in the corresponding areas; the plug plates 23 are movable, and the amount of flour falling can be changed by their movement.
[0044] When the vacuum pump 2 starts, the flour in the flour hopper 1 is pumped into the powder tank 4. Since air will enter the second pipeline 5 along the third pipeline 6 when the vacuum pump 2 starts, the powder tank 4 contains a mixture of air and flour, which then falls into the flour discharging hopper 8. Since air has a flow rate when the vacuum pump 2 starts, the air in the flour discharging hopper 8 mixes with the flour, increasing the gaps between the flour particles, making it difficult for the flour to accumulate. The flour can flow smoothly from the outlet of the flour discharging hopper 8 and be evenly distributed on the flour rolling plate 9. The utility model realizes automatic dough feeding, which is not only highly efficient but also evenly distributes the flour.
[0045] Inspired by the ideal embodiments of the present utility model described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
