[0002] Compound food additives are formula mixtures containing two or more food additives. Compound food additives are made by mixing two or more single varieties of food additives, with or without auxiliary materials, through physical methods in order to improve food quality and facilitate food processing.
[0003] Usually, there are some foreign matter in compound food additive materials before screening. In order to ensure the safety of compound food additives, it is necessary to screen and remove the foreign matter in the compound food additive materials. Generally, the compound food additive materials are filtered through filters, but the current filtering effect is low and the screening and filtration time is long. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for screening compound food additives. Additives are put into a box through a feed pipe, and the additives fall on a screen plate. The motor is started and the rotating rod is driven to rotate through the rotating rod. Since the rotating rod is in contact with the annular plate, a plurality of spherical protrusions are arranged on the annular plate, and a spring and a limit column are arranged on the lower side of the annular plate. When the rotating rod rotates, the annular plate can be squeezed downward by the spherical protrusions, and then reset by the spring, so as to drive the screen plate to vibrate up and down, thereby screening the additives.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A compound food additive screening device comprises a box body, support legs are arranged at the bottom of the box body, a plurality of mounting blocks are arranged circumferentially in the middle part of the box body, a limiting column is arranged above the mounting block, a ring plate is arranged on the top of the limiting column, a spring is sleeved on the limiting column, a plurality of spherical protrusions are arranged circumferentially on the ring plate, a screening device is installed in the ring plate, the screening device comprises a screen frame connected to the bottom of the inner edge of the ring plate, a screen plate is arranged at the bottom of the inner edge of the screen frame, a rotating rod is arranged at the axis center of the box body, a motor for driving the rotating rod is arranged at the bottom of the box body, a rotating rod is arranged at the bottom of the rotating rod, and the bottom of both ends of the rotating rod is abutted against the ring plate.
[0007] Preferably, bristles are provided on the bottom side of the rotating rod, and the free ends of the bristles abut against the screen plate.
[0008] Preferably, a collecting hopper is provided at the lower end of the box body, and a discharge pipe is provided at the lower end of the collecting hopper.
[0009] Preferably, a feed pipe is provided on the top of the box body, and the feed pipe is located directly above the screen plate, and the horizontal height of the bottom of the screen frame is lower than the horizontal height of the bottom of the mounting block.
[0010] Preferably, the sieve plate is detachably connected to the sieve frame.
[0011] Preferably, the discharge pipe is provided with a valve.
[0012] Preferably, the top of the box body is detachably mounted on the box body, and a window is provided on the top of the box body.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model has a simple structure. The rotating rod is driven to rotate by the rotating rod. Since the rotating rod is in contact with the annular plate, a plurality of spherical protrusions are arranged on the annular plate, and a spring and a limit column are arranged on the lower side of the annular plate. When the rotating rod rotates, the annular plate can be squeezed downward by the spherical protrusions. When the rotating rod continues to rotate, the annular plate is reset under the action of the spring, and the rotation work is repeated, which can drive the annular plate to move up and down, and indirectly drive the screen plate to vibrate up and down to screen the additives.
[0015] 2. The bristles at the bottom of the rotating rod of the device that are in contact with the sieve plate can clean the entire sieve plate and gather the sieved foreign matter through the bristles. The cleaned sieve plate can continue to filter the additives that fall on its surface, thereby realizing repeated screening of the sieve plate. At the same time, the additives are screened by vibrating up and down, which can improve the screening efficiency. No additional power source is needed to drive the sieve plate for screening. The screening and cleaning of the sieve plate can be achieved by only one motor, which can effectively save energy.
[0016] 3. The horizontal height of the bottom of the screen frame of this device is lower than the horizontal height of the bottom of the mounting block, which makes it easy for the screened additives to fall completely into the collecting hopper and avoids the screened additives falling on the mounting block, resulting in additives remaining inside the box. Long-term accumulation can easily become a breeding ground for bacteria, mold or other microorganisms, leading to hygiene problems and even food safety hazards.
[0017] 4. The device has a detachable connection between the sieve plate and the sieve frame, which makes it easy to replace sieve plates with different apertures when screening additives with different particle sizes in the later stage, thereby improving the adaptability of the device.
[0018] 5. The window of this device allows the operator to observe the screening situation inside the box at any time. When there are many foreign objects on the screen plate, the detachable top of the box makes it easy to open the box and clean the foreign objects on the screen plate. After the screening work is completed, the inside of the device can be cleaned to facilitate the subsequent screening work to continue. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1
[0026] A composite food additive screening device, the structure is as follows Figure 1-Figure 4 As shown, it includes a box body 1, a supporting leg 2 is arranged below the box body 1, a plurality of mounting blocks are arranged circumferentially in the middle part of the box body 1, a limiting column 12 is arranged above the mounting block, a ring plate 15 is arranged on the top of the limiting column 12, a spring 13 is sleeved on the limiting column 12, a plurality of spherical protrusions 11 are arranged circumferentially on the ring plate 15, a screening device is installed in the ring plate 15, the screening device includes a screen frame 7 connected to the inner bottom of the ring plate 15, a screen plate 6 is arranged at the inner bottom of the screen frame 7, a rotating rod 9 is arranged at the axis of the box body 1, a motor 8 for driving the rotating rod 9 is arranged at the bottom of the box body 1, a rotating rod 10 is arranged at the bottom of the rotating rod 9, and the bottoms of both ends of the rotating rod 10 abut against the ring plate 15. Bristles 14 are arranged on the bottom side of the rotating rod 10, and the free ends of the bristles 14 abut against the screen plate 6.
[0027] When the additive is screened, the additive is put into the box body 1 through the feed pipe 3, and the additive falls on the screen plate 6. The motor 8 is started, and the rotating rod 10 is driven to rotate through the rotating rod 9. Since the rotating rod 10 is in contact with the annular plate 15, a plurality of spherical protrusions 11 are provided on the annular plate 15, and a spring 13 and a limit column 12 are provided on the lower side of the annular plate 15. When the rotating rod 10 rotates, the annular plate 15 can be pressed downward by the spherical protrusions 11. When the rotating rod 10 continues to rotate, the annular plate 15 is reset under the action of the spring 13, and the rotation work is repeated, which can drive the annular plate 15 to move up and down, and indirectly drive the screen plate 6 to vibrate up and down, so as to screen the additive;
[0028] When the rotating rod 10 continues to rotate, the bristles 14 at the bottom of the rotating rod 10 that abut against the sieve plate 6 can clean the entire sieve plate 6, and the sieved foreign matter can be gathered by the bristles 14. The cleaned sieve plate 6 can continue to filter the additives falling on its surface, thereby realizing the repeated screening work of the sieve plate 6. At the same time, the additives are screened by vibrating up and down, which can improve the screening efficiency. There is no need for an additional power source to drive the sieve plate 6 for screening. The screening and cleaning work of the sieve plate 6 can be realized by a motor 8, which can effectively save energy.
[0029] A collecting hopper 5 is disposed at the lower end of the box body 1, and a discharge pipe 4 is disposed at the lower end of the collecting hopper 5. The discharge pipe 4 is provided with a valve.
[0030] The additives screened by the sieve plate 6 fall on the collecting hopper 5. Since the collecting hopper 5 is funnel-shaped, the additives can be discharged from the device through the discharge pipe 4 after being collected by the collecting hopper 5 and fall into the subsequent storage device. Since a valve is provided at the discharge pipe 4, when it is inconvenient to discharge the additives from the device, the discharge pipe 4 can be closed by the valve and the additives can be temporarily stored in the collecting hopper 5, thereby increasing the practicality of the device.
[0031] A feed pipe 3 is provided on the top of the box body 1, and the feed pipe 3 is located directly above the sieve plate 6. The horizontal height of the bottom of the sieve frame 7 is lower than the horizontal height of the bottom of the mounting block.
[0032] Since the feed pipe 3 is arranged directly above the sieve plate 6, when the additive enters the device through the feed pipe 3, it can freely fall on the sieve plate 6, avoiding the additive from falling on the annular plate 15 and failing to effectively screen it. Since the horizontal height of the bottom of the sieve frame 7 is lower than the horizontal height of the bottom of the mounting block, when the annular plate 15 drives the sieve plate 6 to vibrate up and down, the horizontal height of the sieve plate 6 can still be lower than the horizontal height of the bottom of the mounting block, so that the screened additive can fall completely into the collecting hopper 5, avoiding the screened additive from falling on the mounting block, resulting in additives remaining inside the box body 1. Long-term accumulation can easily become a breeding ground for bacteria, mold or other microorganisms, leading to hygiene problems and even food safety hazards.
[0033] Embodiment 2
[0034] On the basis of the first embodiment, the sieve plate 6 is detachably connected to the sieve frame 7. The top of the box body 1 is detachably mounted to the box body 1, and a viewing window is provided on the top of the box body 1.
[0035] Since the particle sizes of food additives are usually not exactly the same, sieve plates 6 with different particle sizes need to be used for screening during the screening process to ensure the quality and consistency of the product. The sieve plate 6 and the sieve frame 7 are detachably connected, so that when screening additives with different particle sizes in the later stage, the sieve plates 6 with different apertures can be replaced, thereby improving the adaptability of the device.
[0036] The viewing window allows the operator to observe the screening situation inside the box 1 at any time. When there are many foreign objects on the sieve plate 6, the detachable top of the box 1 makes it easy to open the box 1 and clean the foreign objects on the sieve plate 6. After the screening work is completed, the inside of the device can be cleaned to facilitate the continuation of subsequent screening work.
[0037] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
