Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of impurity removal devices, and more specifically, to an impurity removal device for food processing. Background Technology
[0002] In the pretreatment process of food raw materials, impurity removal is a crucial step in ensuring product safety. The mixture formed after the raw materials are crushed often contains foreign objects such as sand and gravel with a particle size of 0.2-3mm.
[0003] The current impurity removal system adopts multi-stage synergistic processing: First, the material is fluidized by a vibrating screen with an amplitude of 3-6mm and a frequency of 600-1000 times / minute, so that the denser sand and gravel settle to the bottom collection tank under the action of vibration; then the material enters the permanent magnet drum device, which uses a magnetic field of 5000-8000 Gauss to adsorb ferromagnetic impurities; finally, the material passes through a negative pressure air classifier, which separates light impurities by an airflow speed of 3-5m / s.
[0004] When processed clean raw materials need to be temporarily stored, traditional processes require transferring them to independent storage tanks via bucket elevators. This process not only increases the risk of cross-contamination by 25%-30%, but also leads to inefficient production line layout due to the space occupied by the independent storage tanks. Therefore, a more integrated, multi-functional device can be designed. Utility Model Content
[0005] The purpose of this invention is to provide a food processing impurity removal device that can simultaneously perform preliminary impurity removal on raw materials and temporarily store them.
[0006] This utility model is achieved through the following technical solution: The food processing impurity removal device of this utility model includes a storage tank with an open top, a discharge pipe located at the lower end of the storage tank, a connecting pipe vertically located in the storage tank, a sieve plate horizontally located on the side wall of the connecting pipe, a cover located above the sieve plate with its opening facing downwards, a receiving tray located below the sieve plate, a feeding device connected to the cover, and a driving device for driving the connecting pipe to rise and fall; the sieve plate is conical with a smaller top and a larger bottom, a gap is provided between the lower end wall of the cover and the upper side wall of the sieve plate, the cover is fixedly connected to the connecting pipe, and the receiving tray is fixedly connected to the connecting pipe.
[0007] Furthermore, a vibration motor is connected to the lower side wall of the sieve plate.
[0008] Furthermore, the feeding device includes a feed pipe communicating with the upper end of the cover, and a feeding pump connected to the feed pipe.
[0009] Furthermore, the feed pipe is a flexible tube.
[0010] Furthermore, the driving device includes a hoist positioned above the storage tank and a pull rope connected to the hoist; the pull rope is fixedly connected to the upper end of the connecting pipe.
[0011] Furthermore, the upper end of the storage tank is covered with a cover, and a through hole is opened in the middle of the cover; the diameter of the through hole is larger than the outer diameter of the cover, and the diameter of the through hole is smaller than the outer diameter of the sieve plate.
[0012] Furthermore, the cover has a conical structure that is smaller at the top and larger at the bottom, and the taper of the cover is the same as the taper of the sieve plate.
[0013] Furthermore, it also includes a sliding rod vertically installed in the storage tank, the lower end of the sliding rod being fixedly connected to the inner wall of the storage tank via a first connecting rod, and the upper end of the sliding rod being detachably connected to the upper side of the cover via a second connecting rod; the connecting pipe is sleeved on the outer wall of the sliding rod and slidably connected to the sliding rod.
[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In the food processing impurity removal device of this utility model, dried block or granular food raw materials are fed into the enclosure through a feeding device. The raw materials in the enclosure roll off the screen plates through the gaps between the screen plates and eventually fall from the edge of the screen plates into the storage tank for temporary storage. During this process, small particulate impurities in the raw materials fall through the screen holes on the screen plates into the receiving tray below the screen plates for temporary storage (the impurities can be discharged later). Furthermore, in the initial stage of discharge, the screen plates can be lowered to near the bottom of the storage tank or close to the surface of the existing material near the bottom of the storage tank. This reduces the impact when the material falls from the screen plates into the storage tank, making it less likely to break and generate new small particles. As the amount of raw material in the storage tank gradually increases, the screen plates can be slowly raised using the driving device. This device allows for impurity removal of the processed material before temporary storage, without requiring large-volume impurity removal equipment or excessively increasing processing time. When further processing is required, the raw materials in the storage tank can be discharged directly through the discharge pipe. Attached Figure Description

[0022] Example
[0023] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 6 As shown, the food processing impurity removal device of this embodiment includes a storage tank 11 with an open top, a discharge pipe 12 located at the lower end of the storage tank 11, a connecting pipe 21 vertically located in the storage tank 11, a sieve plate 22 horizontally located on the side wall of the connecting pipe 21, a cover 24 located above the sieve plate 22 with its opening facing downwards, a receiving tray 25 located below the sieve plate 22, a feeding device connected to the cover 24, and a driving device for driving the connecting pipe 21 to rise and fall; the sieve plate 22 is a cone shape with a smaller top and a larger bottom, and there is a gap between the lower end wall of the cover 24 and the upper side wall of the sieve plate 22. The cover 24 is fixedly connected to the connecting pipe 21, and the receiving tray 25 is fixedly connected to the connecting pipe 21. Specifically, during use, dried block or granular food ingredients are fed into the enclosure 24 via a feeding device. The ingredients in the enclosure 24 roll off the screen plates 22 through the gaps between the screen plates 22 and eventually fall from the edges of the screen plates 22 into the storage tank 11 for temporary storage. During this process, small particulate impurities in the ingredients fall through the sieve holes 23 on the screen plates 22 into the receiving tray 25 below the screen plates 22 for temporary storage (the impurities can be discharged later). Furthermore, at the initial discharge stage, the screen plates 22 can be lowered to near the bottom of the storage tank 11 or close to the surface of existing materials at the bottom of the storage tank 11 (as shown in the attached diagram). Figure 3As shown, when the material falls from the screen plate 22 into the storage tank 11, it experiences less impact and is less likely to break and generate new small particles. As the amount of raw material in the storage tank 11 gradually increases, the screen plate 22 can be slowly lifted using a drive device. This device allows for a purification operation on the material before temporary storage during processing, without requiring large-volume purification equipment or excessively increasing processing time. When further processing is needed, the raw material in the storage tank 11 can be directly discharged through the discharge pipe 12.
[0024] In this embodiment, a vibration motor is connected to the lower side wall of the sieve plate 22. Specifically, the vibration motor applies high-frequency vibration to the sieve plate 22, allowing the raw material on the sieve plate 22 to flow more smoothly and avoiding blockage. Since the sieve plate 22 itself vibrates, a soft connection (such as setting a rubber pad) can be used between the sieve plate 22 and the outer wall of the connecting pipe 21 to reduce the effect of the sieve plate 22 on the connecting pipe 21.
[0025] The feeding device in this embodiment includes a feed pipe 26 connected to the upper end of the cover 24, and a feeding pump connected to the feed pipe 26. Specifically, the pump can be used to feed the raw material into the feed pipe 26 and the cover 24, or gravity flow can be used.
[0026] In this embodiment, the feed pipe 26 is a flexible hose. Specifically, since the feed pipe 26 extends into the storage tank 11, a flexible feed pipe 26 is more suitable.
[0027] The driving device in this embodiment includes a hoist positioned above the storage tank 11 and a pull rope 27 connected to the hoist; the pull rope 27 is fixedly connected to the upper end of the connecting pipe 21. Specifically, the hoist can be a common structure consisting of a motor and a winding shaft, such as an electric hoist.
[0028] In this embodiment, the upper end of the storage tank 11 is covered with a cover 13, and a through hole 14 is opened in the middle of the cover 13. The diameter of the through hole 14 is larger than the outer diameter of the cover 14, and smaller than the outer diameter of the sieve plate 22. The cover 13 has a conical structure that is smaller at the top and larger at the bottom, and the taper of the cover 13 is the same as the taper of the sieve plate 22. Specifically, after the sieve plate 22 is moved to the uppermost position, that is, after the upper side of the sieve plate 22 is attached to the lower side of the cover 13 (as shown in the attached figure), the sieve plate 22 is moved to the uppermost position. Figure 2 As shown, the sieve plate 22 can be used to temporarily seal the storage tank 11 to prevent ash and slag from entering. The conical cover 13 allows the cover 13 to fit better with the sieve plate 22.
[0029] In this embodiment, a sliding rod 15 is vertically installed in the storage tank 11. The lower end of the sliding rod 15 is fixedly connected to the inner wall of the storage tank 11 via a first connecting rod 16, and the upper end of the sliding rod 15 is detachably connected to the upper side of the cover 13 via a second connecting rod 17. A connecting pipe 21 is sleeved on the outer wall of the sliding rod 15 and slidably connected to the sliding rod 15. Specifically, the sliding rod 15 can be used to position the connecting pipe 21, allowing the screen plate 22 to move up and down more stably. When it is necessary to clean impurities in the receiving tray 25, the connection between the second connecting rod 17 and the sliding rod 15 must first be disconnected, then the cover plate must be removed, and finally the screen plate 22 and the receiving tray 25 can be taken out.
[0030] In summary, the food processing impurity removal device of this embodiment, during use, feeds dried block or granular food raw materials into the enclosure 24 via a feeding device. The raw materials in the enclosure 24 roll off the screen plates 22 through the gaps between the screen plates 22 and eventually fall from the edge of the screen plates 22 into the storage tank 11 for temporary storage. During this process, small particulate impurities in the raw materials fall through the screen holes 23 on the screen plates 22 into the receiving tray 25 below the screen plates 22 for temporary storage (the impurities can be discharged uniformly later). In addition, at the initial stage of discharge, the screen plates 22 can be lowered to near the bottom of the storage tank 11 or close to the surface of the existing material at the bottom of the storage tank 11 using a driving device. This reduces the impact when the material falls from the screen plates 22 into the storage tank 11, making it less likely to break and generate new small particles. As the amount of raw materials in the storage tank 11 gradually increases, the screen plates 22 can be slowly raised using a driving device. This device allows for the removal of impurities from materials before temporary storage during processing, without requiring bulky removal equipment or excessively increasing processing time. When further processing is needed, the raw materials in storage tank 11 can be discharged directly through discharge pipe 12.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
