Description

Technical Field

[0001] The present application relates to the technical field of crushing, grinding or pulverizing of food processing, and in particular to a chili powder production device based on continuous and efficient screening. Background Art

[0002] At present, the machinery manufacturers are usually limited to using MMT80 mills in the production process of chili powder. In order to achieve industrial-scale production, manufacturers usually choose MMT80 grinding rollers and 83 high square screens, and adopt air-induced lifting and single screw conveyor feeding systems.

[0003] However, this system mainly relies on a single U-shaped screw conveyor to feed the material during the feeding process. This method, due to the lack of mixing technology, easily leads to uneven distribution of chili powder, which in turn affects the consistency of the material entering the mill. When the material enters the mill for grinding inconsistently, it often needs to be stopped for processing, which not only affects production efficiency, but also increases maintenance costs.

[0004] In addition, unqualified materials are usually returned to the feed trough through a single screw conveyor system, which makes it difficult to maintain stable product quality, further exacerbating the fluctuation of product quality. Additional mixing processes are often required in the later stage to ensure product quality.

[0005] In the material lifting process, the process relies on wind power to lift the material to the high square screen. Given the high oil content of peppers, the material easily sticks together to form lumps, causing frequent blockages in the conveying pipeline. Not only is it difficult to clean, but the high square screen must be regularly maintained to meet production needs, which undoubtedly increases time and labor costs and has a negative impact on production efficiency.

[0006] In view of the existence of the above problems, it is particularly necessary to develop a new type of chili powder production equipment to improve or solve some or all of the existing technical problems. Summary of the invention

[0059] In this embodiment: after the chili powder enters the feeding box 1, the two first motors 105 can be started. Under the transmission effect of the two first transmission groups 106, the two first feeding screw conveyors 103 start to rotate. The double-rotation screw conveyor formed by the two first feeding screw conveyors 103 and the U-shaped design of the inner wall at the bottom of the feeding box 1 can keep the chili powder in the feeding box 1 in parallel and stirred all the time. The feeding box 1 and the first feeding screw conveyor 103 are customized according to the production volume to ensure the stability of the operation, and can be maintained for less than ten minutes without human intervention and will not affect the production, so that one staff member can take care of the operation of multiple grinding mills 2 at the same time, which reduces the waste of manpower to a certain extent, and each grinding mill 2 only needs one guide pipe 201 to be connected to the feeding box 1, which ensures that the grinding mill 2 always has a stable supply of chili powder and can operate without stopping. There are two observation holes and position scales on the feeding box 1. When the equipment is running, the workers only need to pay attention to the height of the chili powder scale. Only one worker can intervene, and the grinding mill 2 will not stop.

[0060] The chili powder enters the grinding mill 2 for grinding and is discharged through the grinding rollers after grinding, and naturally falls into three screen boxes 3 in three equal portions. The upper and lower layers of the grinding mill 2 and the screen boxes 3 enable the chili powder to always fall naturally under the effect of gravity, thus solving the problems of high oil content in the chili during the wind-driven lifting process, easy scab formation of chili powder, and frequent blockage and difficulty in cleaning of the chili powder pipeline.

[0061] Furthermore, after the grinding of the mill 2 is completed, the chili powder discharged from the mill 2 will enter the three screen boxes 3 through the distribution pipe 4 respectively, and will directly enter the three screen drums 10. After starting the second motor 803, the transmission effect of the three second transmission groups 801 will eventually rotate the three rotating shafts 8, thereby rotating the external rod 9 and multiple screen plates 902, so as to screen the chili powder in the screen drum 10. At the same time, the screen drum 10 can also discharge unqualified chili powder through the miscellaneous material pipe 303, while the qualified chili powder will pass through the screen drum 10 and enter the discharge pipe 5 after passing through the discharge hopper 304, so that the chili powder is conveyed to the next process through the negative pressure lifting of two medium-pressure air induced draft fans.

[0062] After the screening box 3 discharges the unqualified chili powder through the miscellaneous material pipe 303, the unqualified chili powder falls into the installation box 11. At this time, the third motor 22 is started. The output shaft of the third motor 22 starts to rotate, which will drive the rotating disk 23 to rotate, thereby driving the cam 24 to rotate in a circle. When the cam 24 gradually rotates to a half circle away from the installation box 11, it will pull the traction column 25 to move, thereby driving the parallel shaking box 17 to swing horizontally. When the cam 24 gradually rotates to a half circle close to the installation box 11, it will support the traction column 25 to move, thereby causing the parallel shaking box 17 to swing in the opposite direction. When the third motor 22 drives the rotating disk 23 and the cam 24 to continue to rotate, it will drive the parallel shaking box 17 to swing in a circle, thereby performing a secondary screening on the chili powder introduced into the parallel shaking box 17, and the qualified chili powder will fall into the conveying box 12 through the screening net 18 on the inner wall at the bottom of the parallel shaking box 17.

[0063] The chili powder that has passed the secondary screening passes through the conduction bucket 16 and enters the conveying box 12. At this time, the fourth motor 27 and the fifth motor 30 are started. Under the transmission effect of the third transmission group 28 and the fourth transmission group 31, the second feeding screw conveyor 26 and the third feeding screw conveyor 29 start to rotate, so that the chili powder in the conveying box 12 is horizontally transferred into the side box 13, and then enters the feeding box 1 again through the vertical pipe 14 and the inclined pipe 15 to be mixed and stirred, and so on, so that the quality of the produced products is stable and no mixing and stirring is required at a later stage. The vertical third feeding screw conveyor 29 is simple to operate, no noise, no dust, high stability, and low power.

[0064] During the production process of chili powder, the rotation of the two first feeding screw conveyors 103 can always ensure that the chili powder is kept in parallel stirring in the U-shaped feeding box 1, so that multiple grinders 2 only need one feeding box 1 for feeding, thereby improving production capacity and keeping the grinder 2 in a running production state at all times, while reducing labor consumption. At the same time, the chili powder ground by multiple grinders 2 is discharged through a discharge pipe 5. The entire process only requires adding a medium-pressure fan to the discharge pipe 5 to lift the material, which reduces the configuration of the fan, reduces investment, and reduces noise. The chili powder is circulated between the installation box 11, the vertical tube 14 and the feeding box 1 until the chili powder is screened and qualified and then discharged through the discharge pipe 5. Example

[0065] Based on the chili powder production device based on continuous and efficient screening provided by the first embodiment of the present application, the present application also proposes a second embodiment. The second embodiment is only an optimization scheme of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0066] The second embodiment of the present application is further described below in conjunction with the accompanying drawings and implementation methods.

[0067] Please refer to Figure 14-17 , the chili powder production device based on continuous and efficient screening further includes a fixed rod 32, which further optimizes the external rod 9 in Embodiment 1. The specific optimization is as follows: The fixed rod 32 is fixedly installed at one end of the rotating shaft 8 located inside the sieve box 3. The diameter of the fixed rod 32 is the same as that of the rotating shaft 8. After being fixed by welding, the fixed rod 32 is coaxial with the rotating shaft 8. A plurality of connecting rods 33 are fixedly installed at one end of the fixed rod 32. At one end of the plurality of connecting rods 33, an end rod 34 is fixedly installed. The diameter of the end rod 34 is the same as that of the fixed rod 32, and at the same time, the two are in a coaxial state. The plurality of connecting rods 33 are distributed in a circular array along the edge of the fixed rod 32. The gap formed between two adjacent connecting rods 33 is an avoidance opening. Outer sleeve rings 36 are fixedly sleeved on the outer walls of the fixed rod 32 and the end rod 34. A plurality of positioning boxes 37 are fixedly installed on the outer walls of the two outer sleeve rings 36. The cross-section of the positioning box 37 is in the shape of a "匚". A telescopic column 38 is slidably installed inside each positioning box 37. In this example, the telescopic column 38 needs to penetrate through the circular sleeve for telescopic movement. Here, the circular sleeve is fixedly installed on the top of each positioning box 37. A plurality of sieve plates 902 are fixedly installed on the corresponding two telescopic columns 38. A spring 39 is installed inside each positioning box 37. One end of each spring 39 is fixedly connected to the corresponding telescopic column 38, and the other end of each spring 39 is fixedly connected to the outer wall of the outer sleeve ring 36.

[0068] Rotatable bidirectional threaded rods 35 are installed on the outer walls of the fixed rod 32 and the end rod 34 close to each other. Two transverse moving rings 40 are threadedly sleeved on the outer wall of the bidirectional threaded rod 35. The two transverse moving rings 40 are symmetrically arranged based on the midpoint of the bidirectional threaded rod 35. The two transverse moving rings 40 are respectively located on two threads with opposite rotation directions of the bidirectional threaded rod 35. A plurality of first mounting seats 41 are fixedly installed on the outer walls of the two transverse moving rings 40. Two second mounting seats 42 are fixedly installed on each of the plurality of sieve plates 902. The plurality of first mounting seats 41 and the plurality of second mounting seats 42 are all connected by hinge rods 43. One end of the hinge rod 43 is rotatably connected to the first mounting seat 41, and the other end of the hinge rod 43 is rotatably connected to the second mounting seat 42. The corresponding two hinge rods 43 are symmetrically arranged in a shape like an eight.

[0069] In this embodiment: when it is necessary to produce chili powder of different specifications, it is necessary to replace the sieve cylinders 10 of different mesh numbers. At this time, the staff can rotate the two-way threaded rod 35. The rotation of the two-way threaded rod 35 will drive the two transverse rings 40 to approach or move towards each other. Under the transmission effect of multiple hinged rods 43, the second mounting seat 42 will be opened or contracted with the two-way threaded rod 35 as the center point, so that the sieve plate 902 is opened or contracted, thereby greatly increasing the adaptation range of the sieve box 3 to a great extent, and trying to meet the installation of sieve cylinders 10 of different mesh numbers. After the replacement is completed, the sieve plate 902 can always maintain a clearance fit with the sieve cylinders 10 of different specifications. The setting of the telescopic column 38 can limit the sieve plate 902 so that it can only move in one direction. No matter how large the multiple sieve plates 902 are opened, the spring 39 always maintains a compressed energy storage state, thereby maintaining the current state, avoiding the two-way threaded rod 35 from easily rotating under the action of centrifugal force after the rotating shaft 8 rotates, thereby increasing the stability after adjustment.

[0070] The following aspects should generally be noted in the use of this application. Before starting the equipment, check whether all fasteners are tightened and not loose, confirm that all electrical connections are safe and there are no exposed wires, check whether the U-shaped design of the inner wall of the feeding box 1 is clean and there is no residual chili powder, and confirm that all motors and reducers 107 are normal. Open the loading port at the top of the feeding box 1 and add the dried chili raw material into the feeding box 1. Use the observation port 7 and the position scale to check the amount of chili raw material to ensure that it does not exceed the maximum capacity of the feeding box. Start the first motor 105, drive the first feeding screw conveyor 103 through the first transmission group 106, and start the preliminary mixing and conveying of the chili raw material. Observe the flow of the chili raw material in the feeding box 1 to ensure uniform distribution. Confirm that the mill 2 has been preheated and reached a suitable grinding temperature. Open the feed port of the mill 2 and allow the chili raw material to enter the mill 2 through the guide pipe 201. Confirm that the chili powder ground by the mill 2 can smoothly pass through the distribution pipe 4 and enter each screen box 3, start the second motor 803, drive the rotating shaft 8 through the second transmission group 801, and start the screen plate 902 to screen the chili powder. Observe the miscellaneous material pipe 303 to ensure that unqualified chili powder can be smoothly discharged to the installation box 11, start the third motor 22, and drive the parallel shaking box 17 to perform secondary screening of unqualified chili powder. Check whether the vertical pipe 14 and the inclined pipe 15 are unobstructed to ensure that the screened chili powder can be smoothly returned to the feeding box 1. Confirm that the discharge hopper 304 and the discharge pipe 5 are unobstructed and unblocked, start the medium-pressure fan, and lift the qualified chili powder to the next process through the discharge pipe 5. In addition, regularly record the operating data of the motor, including current, voltage and temperature, check whether the operation of the transmission group is stable and whether there is any abnormal noise, and regularly clean the screen plate 902 to ensure screening efficiency. At the end of production, turn off all motors and power supplies, disconnect the power supply, clean the feed box 1, screen drum 10, conveyor box 12 and parallel shaking box 17, remove the remaining chili powder, and perform necessary lubrication and maintenance on the equipment.
