Description

Technical Field

[0001] This utility model relates to the field of food processing, specifically to a stirring device and stirring equipment for food processing. Background Technology

[0002] Food processing is the process of transforming food raw materials (such as grains and meat products) into a new form of food through certain procedures. During food processing, it is often necessary to use equipment to stir the food to refine the food fibers, making it easier for further processing.

[0003] Existing food ingredient mixing devices have the following problems: due to the existence of mixing dead zones, there may be food that has not been fully mixed in the finished product mixture. Food fibers that have not been fully mixed cannot be refined, resulting in the inability to fully extract the food fibers. This not only affects the taste of the food, but also affects the degree of subsequent absorption of seasonings, resulting in a poor taste in the final product and affecting the company's market competitiveness. Utility Model Content

[0004] Purpose of the utility model: The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a mixing device and equipment for food processing that can fully mix and refine food fibers, so that the mixed food is fluffy and can fully absorb seasonings, which not only facilitates subsequent processing, but also improves the taste of the food through thorough mixing.

[0005] To achieve the above objectives, the first aspect of this application provides a stirring device for food processing, comprising a stirring shaft and a plurality of stirring blades. The roots of the stirring blades are connected to the stirring shaft, and the plurality of stirring blades are divided into several groups on the stirring shaft, with the planes of the stirring blades in different groups forming a certain angle. The number of stirring blades in each group can be the same or different, and the stirring blade can be a single auger-shaped blade or two or more blades with a specific shape.

[0006] Furthermore, the planes of the mixing blades in the same group are parallel to each other, so that they can generate mixing forces in the same direction when rotating, so as to mix the food ingredients evenly.

[0007] Furthermore, the angle between the planes where the different groups of stirring blades are located ranges from 30° to 90°. Through the design of the angle, the different groups of stirring blades can generate stirring forces in multiple directions, so as to further refine the food raw material fibers and improve the stirring effect.

[0008] Furthermore, the working surfaces of adjacent mixing blades are connected to ensure more thorough mixing. Here, the working surface refers to the annular surface formed by the mixing blades rotating 360°, which can contact and mix with the food ingredients. The connection of the working surfaces of adjacent mixing blades can form a continuous mixing working surface during rotation, thereby greatly reducing dead zones in the mixing process.

[0009] Furthermore, one end of the stirring blade is connected to one end of the end connecting device, and the other end of the end connecting device is connected to the end of the stirring shaft. The end connecting device can also generate stirring force when rotating, thereby enabling food ingredients located near the end of the stirring device to be stirred, further reducing dead zones in the stirring process.

[0010] A second aspect of this application provides a mixing device for food processing, including a housing, a plurality of mixing devices as described in any embodiment of the first aspect of this application, and a plurality of motors. Each mixing device is rotatably connected to the housing, and the housing has a feed inlet, with the mixing blades corresponding to the positions of the feed inlets.

[0011] Furthermore, to reduce the use of equipment materials, the stirring shaft is designed with a hollow structure. The hollow structure of the stirring shaft is lighter and helps to improve production efficiency.

[0012] Furthermore, the mixing equipment also includes several external interfaces, which can be connected to a vacuum device or an auxiliary material storage device. If the external interface is used to connect to the auxiliary material storage device, the auxiliary materials (such as flour or water) are fed into the mixing equipment and mixed with the food at the same time as the food is added to the inlet. This not only improves feeding efficiency but also increases the mixing area between the auxiliary materials and the food, resulting in better mixing. If the external interface is used to connect to a vacuum device, the mixing equipment can be made into a vacuum state, thereby reducing air bubbles generated during mixing and improving the texture of the food.

[0013] Furthermore, sealing structures are provided at both ends of the stirring shaft to effectively prevent the stirred material from seeping into the stirring shaft and improve the service life of the stirring shaft.

[0014] Furthermore, a cover is provided on the upper part of the equipment casing. The cover is connected to the first drive device. The cover is positioned corresponding to the feed inlet. After the food raw materials are put into the mixing equipment through the feed inlet, the feed inlet can be sealed by the cover to prevent the mixing material from overflowing during the mixing process.

[0015] Furthermore, the equipment casing is equipped with several discharge ports to output the mixed material. Each discharge port is equipped with a sealing device, which is connected to a second drive device to achieve automated opening and closing, thereby improving output efficiency.

[0016] Furthermore, the mixing equipment also includes a refrigeration device, wherein the refrigeration end of the refrigeration device abuts against the outer shell of the equipment to prevent the equipment from overheating during operation, and at the same time, it can reduce the mixing temperature to preserve food.

[0017] Furthermore, the mixing equipment also includes a conveying device, which comprises a lift and a container, with the container's feeding position corresponding to the feed inlet. By placing food ingredients and other materials into the container and then lifting them via the lift, automated feeding is achieved, improving production efficiency.

[0018] This application has the following beneficial effects:

[0019] This application provides a mixing device and equipment for food processing. The mixing device includes a mixing shaft and several mixing blades. The roots of the mixing blades are connected to the mixing shaft, and the several mixing blades are divided into several groups on the mixing shaft, with the planes of different groups of mixing blades forming a certain angle. The mixing equipment is driven by a motor to rotate the mixing device, which can form multiple working surfaces, thereby greatly reducing the number of dead zones in the mixing process. This allows the fibers of the food raw materials to be fully refined after mixing, thus improving the texture of the food. At the same time, because the fibers are fully refined after mixing, the mixed food raw materials can absorb seasonings more fully, resulting in a better taste. Attached Figure Description

[0029] In the following description, reference is made to the accompanying drawings, which illustrate several embodiments of the present application. It should be understood that other embodiments may also be used, and changes in module or unit composition, electrical and operational aspects may be made without departing from the spirit and scope of this disclosure. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application.

[0030] The following combination Figures 1 to 8 This application is described in detail.

[0031] As described in the background art, during the food raw material processing and mixing process, it is difficult to fully mix and refine the fiber of the food raw materials, thus making it difficult to fully absorb seasonings, and the insufficient mixing also affects the taste of the food. This application provides a mixing device 12 and a mixing equipment 10 for food processing, which can be used for mixing and processing foods such as grains, vegetables, and meats, and can achieve full mixing of food raw materials through the interaction of various components, so that the mixed food raw materials are more fluffy and have a better taste.

[0032] Please see Figure 1 , Figure 1 The diagram shown is a schematic representation of a stirring device in one embodiment of this application. The stirring device 12 includes a stirring shaft 120 and a plurality of stirring blades 121. The roots of the stirring blades 121 are connected to the stirring shaft 120. The plurality of stirring blades 121 are divided into several groups on the stirring shaft 120, and the planes of the stirring blades 121 in different groups form a certain angle. The number of stirring blades 121 in each group can be the same or different. The stirring blade 121 can be a single auger-shaped blade or two or more blades with a specific shape.

[0033] exist Figure 1 In the embodiment shown, the planes of the stirring blades 121 in the same group (arranged in a straight line along the stirring shaft 120) are parallel to each other, so that stirring force in the same direction can be generated when rotating to uniformly stir the food ingredients.

[0034] exist Figure 1In the illustrated embodiment, the included angle α between the planes containing the different groups of stirring blades 121 (the two planes outlined by the dashed lines represent the planes containing the two stirring blades 121 of different groups) ranges from 30° to 90°. By designing the included angle α, the different groups of stirring blades can generate stirring forces in multiple directions to further refine the food raw material fibers and improve the stirring effect.

[0035] exist Figure 1 In the illustrated embodiment, the working surfaces of adjacent stirring blades 121 are connected to ensure more thorough mixing. Here, the working surface refers to the annular surface formed by the stirring blades 121 rotating 360°, which can contact and mix with the food ingredients. The connection of the working surfaces of adjacent stirring blades 121 can form a continuous mixing working surface during rotation, thereby greatly reducing dead zones in the mixing process.

[0036] exist Figure 1 In the illustrated embodiment, one end of the stirring blade 121 is connected to one end of the end connecting device 122, and the other end of the end connecting device 122 is connected to the end of the stirring shaft 120. The end connecting device 122 can also generate a stirring force when rotating, thereby enabling food ingredients located near the end of the stirring device 12 to be stirred, further reducing the stirring dead zone and producing a better stirring effect.

[0037] The second aspect of this application provides a mixing device 10 for food processing; please refer to [link to relevant documentation]. Figure 2 and Figure 3 The mixing device 10 includes a housing 11, several mixing devices 12 as described in any embodiment of the first aspect of this application, and several motors 13. Each mixing device 12 is rotatably connected to the housing 11. The housing 11 has a feed inlet, and the mixing blades 121 are positioned corresponding to the feed inlet. The motors 13 drive the mixing device 12 to rotate, so that the working surface generated by the rotation of the mixing blades 121 on the mixing device 12 can be used to fully mix the food raw materials, so that the fibers of the food raw materials are fully refined after mixing.

[0038] Furthermore, in order to reduce the effect of the stirring gap, in Figure 2 In the embodiment shown, the center distance between the stirring shafts 120 of the two stirring devices 12 does not exceed 50cm, which is greater than the sum of the working surface radii of the stirring blades 121 on the two stirring devices 12 that are in relative positions.

[0039] However, the above arrangement may result in the food ingredients between the two mixing devices 12 not being mixed. To solve this problem, in another embodiment, the center distance between the mixing shafts 120 of the two mixing devices 12 is 30cm, which is less than the sum of the working surfaces of the mixing blades 121 on the two mixing devices 12. However, the working surfaces of the mixing blades 121 on the two mixing devices 12 in relative positions do not interfere with each other and will not collide during operation. This arrangement allows the two mixing devices 12 to be placed closer together, and the mixing blades 121 in the middle area to be more dense, thereby forming a better mixing effect in the middle area.

[0040] Please see Figure 4 , Figure 4 The diagram shows the external interfaces of a mixing device in one embodiment of this application. To reduce air bubbles generated during mixing and ensure thorough mixing of the food ingredients, the mixing device 10 is provided with several external interfaces 14. These external interfaces 14 can be connected to a vacuum device or an auxiliary material storage device. If the external interface 14 is connected to an auxiliary material storage device, auxiliary materials (such as flour or water) are fed into the mixing device simultaneously with the food inlet, improving feeding efficiency and increasing the mixing area between the auxiliary materials and the food, resulting in better mixing. If the external interface 14 is connected to a vacuum device, the mixing device can create a vacuum inside the device, thereby reducing air bubbles generated during mixing and promoting thorough mixing of the food ingredients, thus improving the food's texture.

[0041] In one embodiment, to reduce the use of equipment materials, the stirring shaft 120 is configured as a hollow structure. At the same time, the hollow structure of the stirring shaft 120 is lighter and more conducive to improving production efficiency.

[0042] During stirring, a certain gap exists because the two ends of the stirring device 12 need to rotate. This gap can easily allow the stirred material to seep into the two ends of the stirring device 12, especially when stirring in a vacuum environment. This can affect the service life of the stirring device 12. Therefore, in some embodiments, sealing structures 123 are provided at both ends of the stirring device 12. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 The image shown is a cross-sectional view of the stirring device in one embodiment of this application, as follows: Figure 5 As shown, the stirring device 12 has sealing structures 123 at both ends. When stirring food ingredients under vacuum, the sealing structures 123 can effectively prevent solids or liquids from seeping into the interior of the stirring device 12, thereby improving the service life of the stirring device 12. In one embodiment, the sealing structure 123 is specifically a structure of a sealing bushing plus a sealing ring. In some embodiments, the material of the sealing structure 123 is food-grade PA6.

[0043] Please continue reading. Figure 4 To prevent food ingredients from overflowing during mixing, a cover 15 is provided on the upper part of the equipment housing 11, and the cover 15 is connected to the first driving device 16. The first driving device 16 can be a pneumatic cylinder, a hydraulic cylinder, or other types of driving devices, and this application does not limit this. The cover 15 corresponds to the position of the feed inlet. After the food ingredients are put into the mixing equipment 10 through the feed inlet, the feed inlet can be sealed by the cover 15 to prevent the mixed material from overflowing during the mixing process.

[0044] Furthermore, to facilitate the discharge of the mixed material, in some embodiments, the equipment housing 11 is provided with a plurality of discharge ports 17, wherein each discharge port 17 is provided with a sealing device, which is connected to the second drive device 18, thereby realizing automated opening and closing and improving output efficiency. The second drive device 18 may be a pneumatic cylinder, a hydraulic cylinder, or other types of drive device, and this application does not limit it.

[0045] Because heat is easily generated during mixing, which can damage the equipment and affect the quality of food ingredients, in some embodiments, the housing 11 of the mixing device 10 is equipped with a cooling device 19. Please refer to... Figure 6 , Figure 6 The diagram shown is a schematic of a refrigeration device for a stirring apparatus in one embodiment of this application. The refrigeration end of the refrigeration device 19 abuts against the apparatus housing 11. The refrigeration end of the refrigeration device 19 can abut against the bottom surface of the apparatus housing 11 or multiple sides of the apparatus housing 11. In this embodiment, the refrigeration device 19 is a liquid circulating refrigeration layer covering the apparatus housing 11. The refrigeration device 19 can reduce the temperature generated during stirring, preventing damage to the equipment due to excessive heat and lowering the stirring temperature to preserve food.

[0046] To facilitate the feeding of food ingredients and other auxiliary materials into the mixing equipment 10, in some embodiments, the mixing equipment 10 also includes a conveying device. Please refer to [link to relevant documentation]. Figure 7 and Figure 8 , Figure 7 The diagram shown is a schematic representation of a transport device in one embodiment of this application. Figure 8 Displayed as Figure 7 The illustrated embodiment shows a schematic diagram of the transport device in operation. The transport device includes a lift 20 and a container 21. Food ingredients or other auxiliary materials can be placed inside the container 21. In this embodiment, the lift 20 and the container 21 are hinged together. The container 21 is lifted by the hinge of the lift 20. After being lifted to a certain height, the hinged part of the lift 20 and the container 21 rotates to allow material to be fed into the container 21. The feeding position of the container 21 corresponds to the feeding port of the mixing equipment 10. Automated feeding is achieved through the linkage of the lift 20 and the container 21, improving production efficiency.
