Description

TECHNICAL FIELD

[0001] The utility model relates to the field of beverage production equipment, and specifically relates to a beverage filtering device. BACKGROUND

[0002] With the continuous improvement of consumer requirements for food safety and health quality, beverage production enterprises pay unprecedented attention to the "filtration" link in the production process. Especially in the processing of functional beverages containing dietary fiber, fruit dregs and other natural suspended solids, a certain amount of solid particles is inevitably carried in the raw materials. If these particles are not completely intercepted at the final filling link, it will easily lead to turbidity of bottled beverages, affect the taste of the product, and even cause food safety hazards.

[0003] At present, the mainstream beverage production line is generally equipped with multi-stage filtration devices in the pretreatment stage (such as fruit mud pre-filtration, coarse filtration, fine filtration, etc.) to remove as much as possible large particle solids and micro-suspended solids. However, in actual production, a small amount of fine particles still leaks from the multi-stage filtration and is brought into the finished product container at the filling stage. The current filling head and pipeline system do not integrate a special filtration module, which cannot perform secondary interception on the material entering the filling head, thereby causing these fine particle impurities to mix into the finished product.

[0004] Therefore, it is urgent to design a beverage filtering device at the filling terminal to intercept suspended solids during the filling process, ensure the quality of the health beverage containing fiber and dregs after final filling, and meet the requirements of modern food safety production. SUMMARY

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] Example: See Figures 1-4 This embodiment relates to a beverage filtration device, specifically used for online filtration of functional beverages containing dietary fiber and fruit pomace during the filling process. It includes a filling assembly 10 and a filtration assembly 11. The filling assembly 10 includes a filling tank 12 and a filling head 13, with the filling head 13 fixedly disposed below the filling tank 12. The filtration assembly 11 includes a filter box 14, which is detachably connected to a filter screen 15. The filter screen 15 has a hollow interlayer 16, with one side open and a filter element 17 inserted from the open side. The filter box 14 is connected to the filling tank 12 via the filling head 13, and a discharge port 18 is provided below the filter box 14.

[0023] Specifically, in this embodiment, the filling tank 12 is installed on the production line support and is used to hold the pre-mixed and pre-filtered beverage. The filling head 13 is fixedly installed below the filling tank 12, and the filter box 14 is installed below the filling head 13. It is detachably connected to a filter screen 15, and the filter screen 15 is provided with a replaceable filter element 17. After the beverage enters the filter box 14 from the filling tank 12 under the action of gravity, it first undergoes fine filtration through the filter element 17 inserted into the hollow interlayer 16 of the filter screen 15. The filter element 17 is used to intercept tiny particles and effectively remove residual fine suspended matter in the beverage, ensuring that the functional beverage containing dietary fiber and fruit pomace has a high purity after final filling, taking into account the strict requirements of food taste and safe production.

[0024] The filter box 14 is provided with a sliding groove 19 which is slidably matched with the filter screen plate 15, and one side of the sliding groove 19 is provided with a limiting baffle 20. The filter box 14 is provided with an insertion slot 21 on one side. The limiting baffle 20 is inserted and matched with the insertion slot 21. In the specific use, the filter screen plate 15 with the pre-assembled filter element 17 is aligned with the entrance of the sliding groove 19 provided on the side wall of the filter box 14, and is smoothly slid along the direction of the sliding groove 19. When the filter screen plate 15 slides to the limiting baffle 20, the end face of the baffle is tightly matched with the rear end face of the screen plate, so as to prevent it from continuously sliding out. At the same time, the insertion slot 21 on the limiting baffle 20 is inserted into the outlet of the sliding groove 19 of the filter box 14 and is inserted and matched with the insertion slot 21, so as to realize the positioning and locking of the filter screen plate 15.

[0025] In the embodiment, the side wall of the filter box 14 is provided with a transparent window 22 which is matched with the size of the open side of the hollow interlayer 16 of the filter screen plate 15. The transparent window 22 is made of food-grade high-temperature-resistant transparent polycarbonate material. The transparent window 22 is accurately aligned with the open side of the hollow interlayer 16, so that the operator can observe the accumulation degree of the impurities in the filter element 17 and the interlayer 16 and the change of the beverage flow rate through the window 22 in the non-stop state, and can judge the filtering state in real time. When the impurities are visible in the window 22 or the flow rate is significantly reduced, the filter screen plate 15 is taken out and the filter element 17 is replaced.

[0026] In order to improve the filling efficiency and reduce the replacement time of the filter screen plate 15, a plurality of filter screen plates 15 are provided in the embodiment. One end of the filter screen plate 15 is provided with a pressing block 23, and a pair of first magnetic members 24 is symmetrically arranged on both sides of the pressing block 23. The other end of the filter screen plate 15 is provided with a second magnetic member 25 which is attracted to the first magnetic member 24. In the specific use, the operator can prepare a plurality of filter screen plates 15 with filter elements 17 at the equipment. When replacing, the operator needs to pull out the limiting baffle 20, take the second magnetic member 25 of the standby filter screen plate 15 as a guide, align the first magnetic member 24 of the filter screen plate 15 to be replaced (the two are attracted when they are aligned), push the pressing block 23, push the filter screen plate 15 to be replaced out of the outlet of the sliding groove 19, push the standby filter screen plate 15 into the sliding groove 19, and finally insert the limiting baffle 20 back into the insertion slot 21 to quickly complete the replacement. In the embodiment, the filter box 14 is provided with magnetic sheets 251 which are attracted to the first magnetic member 24 and the second magnetic member 25 at the entrance of the sliding groove 19 and the outlet of the sliding groove 19, respectively, so as to realize the automatic positioning of the filter screen plate 15 after installation. The first magnetic member 24, the second magnetic member 25 and the magnetic sheet 251 are all made of food-grade neodymium iron boron magnet.

[0027] The filling assembly 10 further comprises a stirrer 26, which comprises a stirring shaft 27 and a driving motor 28 for driving the rotation of the stirring shaft 27, and the stirring shaft 27 is circumferentially provided with stirring blades 29. In the embodiment, the stirrer 26 is installed at the central position of the filling barrel 12, the stirring shaft 27 is connected with the output end of the driving motor 28 through an upper flange, and four stirring blades 29 are uniformly distributed on the outer periphery of the stirring shaft 27. The stirrer 26 stirs the beverage and the suspended fibers and fruit residues in the filling barrel 12, so as to reduce the accumulation of impurities at the bottom and help to reduce the filtering load of the filter box 14 to avoid the local blockage of the surface of the filter element 17.

[0028] The filling head 13 comprises a material guiding portion 30 and a material conveying portion 31. The material guiding portion 30 is detachably connected and fixed with the filling barrel 12 through a clamp 32. The lower end of the material guiding portion 30 is provided with a connecting plate 33, the connecting plate 33 is detachably connected and fixed with the filter box 14 through a bolt 34, and the connecting plate 33 is provided with a insertion hole 35 which is slidably matched with the limiting baffle 20. The insertion hole 35 is aligned with the insertion slot 21. In the embodiment, the insertion slot 21 and the matching surface between the insertion slot 21 and the limiting baffle 20 are designed in a sealing structure. After the preliminary positioning is completed by guiding the limiting baffle 20 and through the cooperation of the insertion hole 35 and the insertion slot 21, the bolt 34 is fastened to ensure that there is no leakage between the entire filling head 13 and the filter assembly 11.

[0029] The material guiding portion 30 is provided with a material guiding channel 36, and a material guiding screw 37 is rotatably arranged in the material guiding channel 36. The material guiding screw 37 is connected and fixed with the stirring shaft 27. When the material guiding screw 37 rotates in the material guiding channel 36, it not only conveys the beverage along the axial direction, but also makes the beverage generate a tangential velocity. When the liquid flow enters the filter box 14, it acts on the surface of the filter element 17 in a composite spiral flow state, forms an annular vortex, disperses the positive impact energy, avoids the direct impact of the beverage on the pore mesh of the filter element 17, thereby preventing the local force collapse or damage of the filter element 17; at the same time, the spiral flow can also uniformly distribute the suspended solid objects on the mesh surface of the filter element 17, reduce the local blockage, significantly prolong the service life of the filter element 17 and improve the stability of the filtering process.

[0030] In the embodiment, the material conveying portion 31 is designed in a conical structure, and the inner cavity of the material conveying portion 31 is gradually convergent along the axial direction from top to bottom to form a conical profile of a material conveying channel 38. The beverage conveyed from the material guiding screw 37 flows along the inner wall surface of the material conveying channel 38, and is guided by the circular arc transition curve, so as to further reduce the impact force of the subsequent filter element 17 on the filter mesh plate 15 and the filter element 17.

[0031] The above described in the specification is only an example of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace, as long as it does not deviate from the content of the specification of the present application or beyond the scope defined by the claims, it shall belong to the protection scope of the present application.
