[0025] 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] The existing technology is mainly manual open-type and family workshop-style operation, which is difficult to stabilize large-scale industrial production. The specific disadvantages are as follows:

[0029] 1. Product quality control is difficult. The current processing mainly relies on manual operation, and precise process control is impossible. Pre-mixing, wet mixing, drying and other links completely rely on the operator's experience and judgment, and the stability between product batches is poor.

[0030] 2. The risk of microbial contamination is high. The raw materials contain a large amount of protein, oil, sugar, mineral salts and other ingredients that are easily adsorbed on the surface of the equipment. In traditional processes, there are many blind spots in the internal cleaning of trough or paddle dry mixers and dough mixers, and they can only be cleaned manually. It is extremely difficult to clean thoroughly and the cleaning difficulty is huge. Once the cleaning is not thorough, microorganisms will multiply and directly contaminate the product, causing serious food safety risks.

[0031] 3. Low production efficiency. Currently, the processes used include manual hopper feeding, material premixing, dough mixer wet mixing, stamping and forming, and packaging. The materials need to be manually transferred repeatedly by multiple people, and the production efficiency is very low.

[0032] 4. Dust pollution. The existing process is an open production process, that is, the material mixing process will cause serious dust dispersion, which not only pollutes the environment, but also poses a hidden danger to the occupational health of production workers and production operation safety (dust explosion risk).

[0033] In order to solve the above technical solutions, Figure 1 and Figure 2 As shown, in this embodiment, the food powder compression molding production line includes: a first feeding device 10, a granulating device 20, a drying device 30, a second feeding device 40, a briquetting device 50, a first sterilizing device 60 and a packaging device 70. The inlet of the granulating device 20 is connected to the outlet of the first feeding device 10. The inlet of the drying device 30 is connected to the outlet of the granulating device 20. The inlet of the second feeding device 40 is connected to the outlet of the drying device 30. The inlet of the briquetting device 50 is connected to the outlet of the second feeding device 40. The inlet of the first sterilizing device 60 is connected to the outlet of the briquetting device 50. The packaging device 70 is connected to the outlet of the first sterilizing device 60.

[0034] According to the technical solution of this embodiment, the first feeding device 10 is connected to the inlet of the granulating device 20, the inlet of the drying device 30 is connected to the outlet of the granulating device 20, the inlet of the second feeding device 40 is connected to the outlet of the drying device 30, the inlet of the briquetting device 50 is connected to the outlet of the second feeding device 40, the inlet of the first sterilizing device 60 is connected to the outlet of the briquetting device 50, and the packaging device 70 is connected to the outlet of the first sterilizing device 60. Through the above-mentioned settings, the material is transported to the granulating device 20 through the first feeding device 10, and granulation is achieved. After granulation, it is transported to the drying device 30, and the granular material is dried. Then it is transported to the briquetting device 50 through the second feeding device 40, and briquetting is achieved. After briquetting is formed, it is sterilized by the first sterilizing device 60 to ensure the food safety of the formed material, and finally it is packaged by the packaging device 70. In this way, during the processing, no manual operation is required, and it can always move in a sealed device to avoid contact with the external environment, which can further ensure the safety of food. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that food safety cannot be guaranteed during the compression molding process of food powder.

[0035] like Figures 1 to 5 As shown, in this embodiment, the granulating device 20 includes a container 21, a stirring structure 22 and a baffle plate 23. The container 21 has a receiving chamber 211. The stirring structure 22 is rotatably arranged on the bottom wall of the receiving chamber 211. An outlet is arranged on the side wall of the container 21. The baffle plate 23 is hingedly connected to the inner side wall of the container 21 so that the baffle plate 23 can be swingably arranged. The swing axis of the baffle plate 23 is arranged parallel to the rotation axis of the stirring structure 22. The powdered material and the liquid material are both transported into the container 21. The stirring structure 22 stirs the powdered material and the liquid material to mix and form a granular structure, which can then be transported to the drying device 30 through the outlet to avoid excessive humidity of the granular structure. At the same time, the baffle plate 23 can stop the granular structure, so that the granular structure can enter the outlet more easily.

[0036] like Figures 1 to 5 As shown, in this embodiment, the baffle plate 23 has an outward swing state and an inward swing state. When the baffle plate 23 moves from the inward swing state to the outward swing state, the distance between the baffle plate 23 and the center line of the container 21 gradually decreases. When the baffle plate 23 is in the outward swing state, the distance between the baffle plate 23 and the center line of the container 21 is smaller than the distance between the baffle plate 23 and the center line of the container 21 when the baffle plate 23 is in the inward swing state. When the baffle plate 23 is in the outward swing position, the granular structure can be stopped, thereby making it easier for the granular structure to enter the outlet. When the baffle plate 23 is in the inward swing position, the baffle plate can avoid the granular structure.

[0037] like Figures 1 to 5As shown, in this embodiment, the granulating device 20 further includes a shearing structure 24, which includes a driving member 241 and a shearing blade 242 drivingly connected to the driving member 241, the shearing blade 242 is rotatably arranged in the container 21, the driving member 241 is arranged outside the container 21, and the axis of the driving member 241 is arranged perpendicular to the rotation axis of the stirring structure 22. The driving member 241 can drive the shearing blade 242 to rotate, thereby switching the mixture of the powder material and the liquid material, thereby forming a granular structure.

[0038] like Figure 1 and Figure 6 As shown, in this embodiment, the food powder compression molding production line further includes a first manipulator 81, a second manipulator 82 and a second sterilizing device 83, wherein the second sterilizing device 83 is located between the first manipulator 81 and the second manipulator 82, and the second manipulator 82 is located between the second sterilizing device 83 and the first feeding device 10. The first manipulator 81 can clamp the material bag and place it at the second sterilizing device 83, and sterilize the material bag by the second sterilizing device 83. After the sterilization is completed, the material bag is clamped and stacked by the second manipulator 82, which can not only sterilize the material bag but also avoid manual operation, thereby improving production efficiency.

[0039] like Figure 1 As shown, in this embodiment, the second sterilizing device 83 includes a tunnel structure and a sterilizing structure arranged in the tunnel structure. The material bag can move in the tunnel structure, and the material bag is sterilized by the sterilizing structure. Specifically, the sterilizing device is an ultraviolet sterilizing structure.

[0040] like Figures 1 to 3 As shown, in this embodiment, the first feeding device 10 includes a powder storage tank 11, a liquid storage tank 12 and a first vacuum feeder 13. The first vacuum feeder 13 is arranged between the powder storage tank 11 and the granulating device 20. The powder storage tank 11 is connected to the granulating device 20 through the first vacuum feeder 13, and the liquid storage tank 12 is connected to the granulating device 20. The powder material is placed in the powder storage tank 11, and the liquid material is placed in the liquid storage tank 12. The first vacuum feeder 13 can transport the powder material to the granulating device 20, and the liquid material in the liquid storage tank 12 is pumped into the granulating device 20 through the pump body.

[0041] like Figures 1 to 3 As shown, in this embodiment, the first feeding device 10 further includes a powder feeding station 14 and a conveying structure 15, and the powder feeding station 14 is connected to the powder storage tank 11 through the conveying structure 15. The material bag is placed in the powder feeding station 14, and the powdered material in the material bag is then conveyed to the powder storage tank 11 through the conveying structure 15.

[0042] Specifically, the conveying structure 15 includes a barrel and a screw disposed in the barrel. The screw is rotatably disposed in the barrel. When the screw rotates, the powdered material can be transported to the powder storage tank 11 .

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the drying device 30 includes a dryer 31 and a vacuum structure 32 connected to the dryer 31. The above arrangement can ensure the safety of food.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the first sterilizing device 60 includes a microwave sterilizer and an air cooler. The microwave sterilizer can sterilize the formed material.

[0045] The technical solution of this embodiment connects the powder feeding station 14, the powder storage tank 11, the liquid storage tank 12, the granulating device 20, the drying device 30, and the briquetting device 50 through a dense conveying system and a stainless steel pipeline to realize fully enclosed pipeline material transportation, and then equipped with a first sterilizing device 60, a second sterilizing device 83, a packaging device 70, a metal detector or an X-ray detector to realize full-process automated production without human contact throughout the process. The technical solution of this embodiment replaces the traditional process of manual hopper feeding, trough or paddle premixing, dough mixer wet mixing and other multi-step processes, and the production efficiency is increased by more than 148%, and the number of operators is reduced from 12-16 to 3-4. At the same time, the drying device 30 can also further crush the semi-finished wet granulation product to control the moisture content to meet the needs of different product types. The technical solution has a high degree of automation, is suitable for large-scale industrial production, has good stability between product batches, and the dry-wet mixing process is automatically cleaned in situ, the risk of microbial contamination is extremely low, and the entire production process is almost completely carried out under closed conditions, without dust, and the occupational health of employees is guaranteed.

[0046] The working process of the food powder compression molding production line of this embodiment is as follows:

[0047] When in use, the first manipulator 81 is used to unstacker the whole pallet of materials, and then the materials are sent to the second sterilization device 83 for air showering and sterilization of the outer bag of the packaging. The treated materials are sent to the belt conveyor, and the second manipulator 82 re-stacks the materials into pallets to wait for feeding. The operator opens the cover of the powder feeding station 14 and quantitatively feeds the powder materials. The materials are transported to the powder storage tank 11 for temporary storage under the action of the conveying structure 15. At the same time, grease and other liquid materials are quantitatively poured into the liquid storage tank 12 for temporary storage in insulation.

[0048] At the beginning of production, the powder material in the powder storage tank 11 is first transported to the granulating device 20 by the first vacuum feeder 13. After the stirring structure 22 starts to rotate for a certain period of time, the material in the liquid storage tank 12 is pumped into the granulating device 20, and the stirring structure 22 and the shearing structure 24 are started to mix at the same time. After a certain period of time, the discharge valve is opened. When a small amount of material is discharged, the baffle plate 23 is opened to speed up the material discharge speed (when the material is discharged too slowly, it will be excessively granulated). The mixed material is sucked into the dryer 31 for drying and granulation under the action of the vacuum structure 32. After the granulation is dried, the material is sent to the briquetting device 50 at a constant speed by the second feeding device 40 for briquetting. The compressed product is sent to the first sterilization device 60 by the conveyor belt for microwave sterilization, and then air-cooled after sterilization, and finally sent to the packaging device 70 by the conveyor belt to complete the automated production and processing.

[0049] For some materials with high moisture content in the final product, when the mixed materials are sucked into the dryer 31 under the action of the vacuum structure 32, only the spiral ribbon mixing function can be started without starting the heating function. The dryer 31 can also be directly short-circuited, and the materials are directly sent to the briquetting device 50 at a constant speed from the second feeding device 40 for briquetting.

[0050] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0051] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0053] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
