Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food additive drying, in particular to a food additive drying device. Background Art
[0002] Food additives refer to chemical synthetic or natural substances added to food to improve the quality, color, aroma and taste of food, as well as for the needs of anti-corrosion and processing technology. In the use of food additives, in addition to ensuring their due functions and roles, the most important thing is to ensure the safety and hygiene of food. In the process of producing food additives, a drying oven is needed to dry them, which not only makes them more hygienic, but also can make them have a longer storage time to avoid the problem of microbial growth and pollution. During the drying process, it is necessary to heat up the additives to accelerate the evaporation of the moisture inside the food additives, so as to achieve the drying effect. However, when the traditional drying oven dries additives with smaller particles or irregular shapes, due to more contact points between the food additives, they are more likely to agglomerate during the drying process, affecting the drying effect of the drying device on the food additives. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a food additive drying device. Through a vibrator, the filter plate can be driven to vibrate and disperse the agglomerated food additives, ensuring the dispersion of the agglomerated food additives. After drying and dispersion, filtration is carried out through the filter plate, which can disperse the agglomerated food additives while drying the food additives, effectively ensuring the drying work of the food additives and improving the drying quality of the food additives.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A food additive drying device includes a box body. A driving device, a feeding device and a dehumidifying device are arranged at the top of the box body. Supporting legs are arranged at the bottom end of the box body. The feeding device includes a feeding pipe. An installation hole is formed at the top of the box body, and the feeding pipe is rotatably installed in the installation hole. A feeding hopper is arranged at the top end of the feeding pipe. A material scattering device is installed at the lower end of the feeding pipe. A vibrator is installed at the bottom end of the feeding pipe. A power output end of the vibrator is installed with a filter plate adapted to the inner diameter of the box body. A heater is installed at the bottom of the filter plate. A stirring device is arranged inside the feeding pipe.
[0006] Preferably, filter holes are arranged in an array on the filter plate, and material scattering columns are arranged in an array on the filter plate between the filter holes.
[0007] Preferably, the driving device includes a first motor installed at the top end of the box body, and the power output end of the first motor is connected to the blanking pipe through a transmission belt.

[0009] Preferably, the dehumidifying device includes an exhaust duct communicating with the inside of the box body. A fan blade and a blower are installed in the exhaust duct, and a protective net is provided at the top end of the exhaust duct.
[0010] Preferably, the stirring device includes a mounting rack installed on the top of the box body. A second motor is provided at the top of the mounting rack, a stirring shaft coaxial with the blanking pipe is provided at the bottom of the mounting rack, multiple groups of stirring teeth are arranged in an array on the stirring shaft, and the power output end of the second motor is connected to the top of the stirring shaft.
[0011] Preferably, a collecting hopper is provided at the bottom end of the box body, a discharge port is provided at the bottom end of the collecting hopper, a heating rod is arranged inside the stirring shaft, and a heating layer is provided on the inner wall of the collecting hopper.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. The structure of the present utility model is simple. The vibrator can drive the filter plate to vibrate and disperse the caked food additives, ensuring the dispersion of the caked food additives. After drying and dispersion, the food additives are filtered through the filter plate, which can disperse the caked food additives while drying the food additives, effectively ensuring the drying work of the food additives and improving the drying quality of the food additives.
[0014] 2. The stirring device inside the blanking pipe of this device can rotate in the reverse direction, preventing the food additives from caking inside the blanking pipe and blocking the inside of the blanking pipe, ensuring the drying efficiency of the food additives. The water vapor generated during the drying process is extracted from the inside of the box body by the dehumidifying device at the top of the box body, ensuring that the inside of the box body is in a dry state and ensuring the drying effect of the food additives.
[0015] 3. By arranging the material scattering columns on the top of the filter plate in this device, the caked food additives continuously collide with the material scattering columns while vibrating, further improving the effect of dispersing the caked additives and ensuring that the food additives filtered by the filter plate are in a qualified granular state.
[0016] 4. The device drives the stirring teeth to rotate through the stirring shaft, which can disperse the agglomerated food additives inside the feeding pipe, ensuring that the size of the agglomerated food additives discharged by the subsequent material spreading device is small, facilitating the secondary dispersion by the later vibrator and material spreading column. At the same time, the stirring shaft drives the stirring teeth to rotate, which can prevent the food additives from blocking inside the feeding pipe and ensure the dispersion efficiency of the food additives.
[0017] 5. By arranging a heating rod inside the stirring shaft, when the food additives are put into the feeding pipe, the heating rod can preheat the food additives. Preheating can increase the initial temperature of the food additives, thereby reducing the time required to reach the completely dried state and further improving the drying efficiency. The food additives filtered by the filter plate fall into the aggregate hopper. Since a heating layer is provided on the side wall of the aggregate hopper, the heating layer can continue to reduce the moisture content in the dried food additives, ensuring the drying effect, which is particularly important for food additives with extremely low humidity requirements. And the heating layer helps the moisture inside and on the surface of the material to evaporate more evenly, avoiding local over-wetting or over-drying, and also preventing the food additives from being directly filtered through the filter holes on the filter plate before being completely dried, further ensuring the drying quality.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment 1
[0025] A food additive drying device has a structure as Figures 1-4 shown, including a box body 1. A driving device, a feeding device, and a dehumidifying device are arranged at the top of the box body 1. Support legs 2 are arranged at the bottom end of the box body 1. The feeding device includes a feeding pipe 19. An installation hole is opened at the top of the box body 1, and the feeding pipe 19 is rotatably installed in the installation hole. A feeding hopper 3 is arranged at the top end of the feeding pipe 19. A material scattering device is installed at the lower end of the feeding pipe 19. A vibrator 13 is installed at the bottom end of the feeding pipe 19. A filter plate 12 adapted to the inner diameter of the box body 1 is installed at the power output end of the vibrator 13. A heater 15 is installed at the bottom of the filter plate 12. A stirring device is arranged inside the feeding pipe 19.
[0026] Continuously put the food additive to be dried into the feeding hopper 3. Since the bottom of the feeding hopper 3 is connected to the feeding pipe 19, the food additive entering the feeding pipe 19 descends to the bottom of the feeding pipe 19. As the amount of the put food additive gradually increases, the food additive will accumulate at the bottom of the feeding pipe 19. Since the bottom of the feeding pipe 19 is communicated with the material scattering device, part of the food additive accumulated at the bottom of the feeding pipe 19 will enter the interior of the material scattering device;
[0027] With the start of the driving device, the driving device can drive the feeding pipe 19 to rotate, and the food additive accumulated at the bottom of the feeding pipe 19 will move towards the interior of the material scattering device under the action of centrifugal force. After the material scattering device scatters and sprinkles the food additive on the filter plate 12, since the heater 15 is installed at the bottom of the filter plate 12, the heater 15 can heat the filter plate 12 to realize the drying of the food additive falling on the filter plate 12. The non-caked food additive passes through the filter plate 12 by filtration, while the caked food additive remains on the filter plate 12;
[0028] With the start of the vibrator 13, the vibrator 13 can drive the filter plate 12 to vibrate and disperse the caked food additive, ensuring the dispersion of the caked food additive. After drying and dispersion, it passes through the filter plate 12 by filtration. It can disperse the caked food additive while drying the food additive, effectively ensuring the drying work of the food additive and improving the drying quality of the food additive;
[0029] While drying the food additive, the stirring device inside the feed pipe 19 can rotate in the reverse direction to prevent the food additive from caking inside the feed pipe 19, blocking the inside of the feed pipe 19, ensuring the drying efficiency of the food additive. The water vapor generated during the drying process is extracted from the inside of the box body 1 by the dehumidifying device at the top of the box body 1, ensuring that the inside of the box body 1 is in a dry state and ensuring the drying effect of the food additive.
[0030] The filter holes are arranged in an array on the filter plate 12, and the material dispersing columns 14 are arranged in an array on the filter plate 12 between the filter holes.
[0031] To prevent some caked food additives from not being effectively dispersed under the vibration of the vibrator 13, by arranging the material dispersing columns 14 on the top of the filter plate 12, the caked food additives collide with the material dispersing columns 14 continuously while vibrating, further improving the effect of dispersing the caked additives and ensuring that the food additives filtered by the filter plate 12 are in a qualified granular state.
[0032] The driving device includes a first motor 5 installed at the top end of the box body 1, and the power output end of the first motor 5 is connected to the feed pipe 19 through a transmission belt 7. The material dispersing device includes a material dispersing box 11, and an opening communicating with the material dispersing box 11 is arranged on the side surface of the bottom end of the feed pipe 19. The length of the material dispersing box 11 is adapted to the radius of the box body 1, and an opening is provided on the side surface in the length direction of the material dispersing box 11.
[0033] By starting the first motor 5, when the power output end of the first motor 5 rotates, it can drive the feed pipe 19 to rotate inside the box body 1 through the transmission belt 7, thereby ensuring that the dispersing box rotates inside the box body 1, and scattering the food additive entering the inside of the dispersing box onto the filter plate 12 through the opening on the side area, ensuring that the food additive scatters evenly and improving the drying efficiency of the food additive.
[0034] The dehumidifying device includes an exhaust air pipe 8 communicating with the inside of the box body 1. A fan blade 17 and a blower 16 are installed in the exhaust air pipe 8, and a protective net 18 is arranged at the top end of the exhaust air pipe 8.
[0035] By driving the fan blade 17 to rotate through the blower 16, the water vapor generated by drying the food additive inside the box body 1 is discharged from the inside of the box body 1, ensuring that the inside of the box body 1 is in a relatively dry environment, facilitating the continuous drying work of the food additive. The protective net 18 arranged at the top of the exhaust air pipe 8 can prevent external falling objects from entering through the exhaust air pipe 8 and affecting the food additive inside the box body 1, and at the same time can prevent operators from accidentally putting their hands or other parts into the exhaust air pipe 8 and causing harm to the operators.
[0036] The stirring device includes a mounting frame 4 installed on the top of the box body 1. A second motor 6 is provided at the top of the mounting frame 4. A stirring shaft 9 coaxial with the feeding pipe 19 is provided at the bottom of the mounting frame 4. A plurality of groups of stirring teeth 10 are arranged in an array on the stirring shaft 9. The power output end of the second motor 6 is connected to the top of the stirring shaft 9.
[0037] By rotating the second motor 6, the stirring shaft 9 and the feeding pipe 19 can be driven to rotate in the opposite direction. When the food additive is put into the feeding pipe 19, the stirring shaft 9 drives the stirring teeth 10 to rotate, and the agglomerated food additive inside the feeding pipe 19 can be dispersed, ensuring that the size of the agglomerated food additive discharged by the subsequent scattering device is small, which is convenient for the subsequent vibrator 13 and the scattering column 14 to disperse it secondary. At the same time, the stirring shaft 9 drives the stirring teeth 10 to rotate, which can prevent the food additive from being blocked in the feeding pipe 19 and ensure the dispersion efficiency of the food additive.
[0038] Embodiment 2
[0039] On the basis of Embodiment 1, a collecting hopper 20 is provided at the bottom end of the box body 1. A discharge port is provided at the bottom end of the collecting hopper 20. A heating rod is provided inside the stirring shaft 9. A heating layer is provided on the inner wall of the collecting hopper 20.
[0040] In order to further improve the drying efficiency, by providing a heating rod inside the stirring shaft 9, when the food additive is put into the feeding pipe 19, the food additive can be pre-heated by the heating rod. The pre-heating can increase the initial temperature of the food additive, thereby reducing the time required to reach the completely dried state and further improving the drying efficiency. The food additive filtered by the filter plate 12 falls into the collecting hopper 20. Since a heating layer is provided on the side wall of the collecting hopper 20, the heating layer can continue to reduce the moisture content in the dried food additive, ensuring the drying effect, which is particularly important for food additives with extremely low humidity requirements. And the heating layer helps the moisture inside and on the surface of the material to evaporate more evenly, avoiding local over-wet or over-dry, and also can prevent the food additive from being directly filtered through the filter holes on the filter plate 12 before being completely dried, further ensuring the drying quality.
[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes, increases or decreases that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
