Description

Technical Field

[0001] This utility model relates to the field of fragrance and flavor production technology, specifically a multi-stage filtration device for fragrance and flavor production. Background Technology

[0002] Fragrances, also known as flavoring ingredients, are substances that can be smelled or tasted. They are raw materials used to formulate fragrances. Except for a few varieties, most fragrances cannot be used alone. Fragrances are divided into natural fragrances and artificial fragrances. Natural fragrances include animal-derived natural fragrances and plant-derived natural fragrances; artificial fragrances include isolated fragrances and synthetic fragrances. Currently, fragrances need to be graded by size during the production process to meet the needs of different customers.

[0003] A search revealed a Chinese patent document disclosing a multi-stage filtration device for flavor and fragrance production [Announcement No.: CN219092658U]. This multi-stage filtration device for flavor and fragrance production includes a support, an outer cover, a coarse filter cylinder, a medium filter cylinder, and a fine filter cylinder. The outer cover is mounted on the support, and the coarse filter cylinder, medium filter cylinder, and fine filter cylinder are sequentially arranged inside the outer cover.

[0004] The multi-stage filtration device disclosed in this patent can filter fragrances and flavorings into the filter cylinder in three stages—fine, medium, and coarse—by rotating the filter cylinder. During the rotation of the filter cylinder, the fragrances and flavorings are constantly turned over, making the sieving of impurities in the fragrances and flavorings more thorough. However, when the fragrances and flavorings are filtered and rotated in the filter cylinder, some of the larger fragrances and flavorings will accumulate together, causing small particles to easily get mixed in between them. During the subsequent turning process, some small impurities will be carried away by the medium and coarse fragrances and flavorings, thus affecting the filtration effect. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage filtration device for the production of fragrances and flavors, so as to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage filtration device for fragrance and flavor production, comprising a base, a filter shell, a rotating cylinder, and a plurality of filter holes formed on its surface, and further comprising:

[0007] Movable rods are connected to both sides of the top of the filter housing. One end of the movable rod is fixed with a pressure plate, and the other end of the movable rod is fixed with a knocking plate. A spring is sleeved on the surface of the movable rod, and the two ends of the spring are fixed to the pressure plate and the top of the filter housing, respectively.

[0008] A rotating rod is rotatably connected to the top of the filter housing, and cams are fixed on both sides of the surface of the rotating rod. A drive structure for driving the flipping cylinder and the rotating rod to rotate is provided on the left side of the filter housing.

[0009] The feed hopper is located on the right side of the filter shell. The bottom of the feed hopper is connected to the filter shell by a feed pipe. The filter plate is movably connected inside the feed hopper.

[0010] A fixed frame is fixed to the back of the feed hopper. A first motor is fixed to the top of the fixed frame, and the output shaft of the first motor is bolted to a movable disc. A connecting rod is hinged between the top of the movable disc and the back of the filter plate.

[0011] Preferably, the drive structure includes a second motor fixed to the left side of the filter housing, a drive wheel fixed to the output shaft of the second motor, and a driven wheel that is connected to the drive wheel via a belt. The other side of the drive wheel is fixed to the rotating shaft of the tilting cylinder, and the other side of the driven wheel is fixed to the left end of the rotating rod.

[0012] Preferably, the top of the pressure plate is rotatably connected to a plurality of rollers, and the surfaces of the rollers are in rolling connection with the cam.

[0013] Preferably, a sliding plate is fixed to the right side of the filter plate, and the surface of the sliding plate is movably connected to the inside of the feed hopper.

[0014] Preferably, the bottom of the feed hopper is connected to a discharge pipe, and the other end of the discharge pipe is connected to the right side of the base.

[0015] Preferably, the aperture of the filter plate is the same as that of several apertures on the right side of the surface of the rotating cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, after the spices fall into the hopper, the rotation of the movable disc causes the connecting rod to deflect, which in turn causes the filter plate to move back and forth inside the hopper. This provides initial filtration of the spices on the filter plate surface, thereby improving the subsequent filtration effect. Simultaneously, as the rotating cylinder flips the spices, the rotating rod drives the cam to rotate, causing the cam's protruding part to rotate downwards. This moves the pressure plate, movable rod, and tapping plate downwards, facilitating the tapping of the rotating cylinder. This not only improves filtration efficiency but also prevents clogging.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, a multi-stage filtration device for fragrance and flavor production includes a base 1, a filter shell 2 fixed to the top of the base 1, a rotating cylinder 3 rotatably connected inside the filter shell 2, and several filter holes 4 formed on the surface of the rotating cylinder 3. Movable rods 7 are movably connected to both sides of the top of the filter shell 2. A pressure plate 8 is fixed to one end of the movable rod 7, and a knocking plate 9 is fixed to the other end. A spring 10 is fitted onto the surface of the movable rod 7, and both ends of the spring 10 are fixed to the pressure plate 8 and the top of the filter shell 2, respectively. A rotating rod 5 is rotatably connected to the top of the filter shell 2, and cams 6 are fixed to both sides of the surface of the rotating rod 5. Several rollers 11 are rotatably connected to the top of the pressure plate 8, and the surfaces of the rollers 11 roll against the cams 6, thus reducing the contact between the cams 6 and the pressure plate 8. The friction between the pressure plates 8 is to facilitate better application of force to the pressure plates 8 later. A drive structure 12 for rotating the tilting cylinder 3 and the rotating rod 5 is provided on the left side of the filter shell 2. A feed hopper 13 is provided on the right side of the filter shell 2. A feed pipe 14 is connected between the bottom of the feed hopper 13 and the filter shell 2. A filter plate 15 is movably connected inside the feed hopper 13. The aperture of the filter plate 15 is the same as that of several apertures on the right side of the tilting cylinder 3, so that smaller impurities can be filtered. A fixing frame 17 is fixed on the back of the feed hopper 13. A first motor 18 is fixed on the top of the fixing frame 17. The output shaft of the first motor 18 is bolted to a movable disc 19. A connecting rod 20 is hinged between the top of the movable disc 19 and the back of the filter plate 15.

[0026] The drive structure 12 includes a second motor 121, a drive wheel 122, and a driven wheel 123. The second motor 121 is fixed to the left side of the filter housing 2. The output shaft of the second motor 121 is fixed to one side of the drive wheel 122. The drive wheel 122 is connected to the driven wheel 123 via a belt. The other side of the drive wheel 122 is fixed to the rotating shaft of the tilting cylinder 3. The other side of the driven wheel 123 is fixed to the left end of the rotating rod 5. Thus, when the tilting cylinder 3 is rotated, the second motor 121 can be started, which drives the drive wheel 122 to rotate. At the same time, the driven wheel 123 is rotated via the belt, which in turn drives the tilting cylinder 3 and the rotating rod 5 to rotate.

[0027] A slide plate 21 is fixed to the right side of the filter plate 15, and the surface of the slide plate 21 is movably connected to the inside of the feed hopper 13. This can provide auxiliary support for the filter plate 15 and maintain its stability when moving.

[0028] The bottom of the feed hopper 13 is connected to the discharge pipe 16, and the other end of the discharge pipe 16 is connected to the right side of the base 1, which facilitates the unified collection and treatment of impurities.

[0029] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0030] Working principle: In use, the drive structure 12 drives the tilting cylinder 3 and the rotating rod 5 to rotate, which in turn drives the cam 6 to rotate as well. This causes the protruding part of the cam 6 to rotate downward, thereby applying downward force to the pressure plate 8, the movable rod 7, and the striking plate 9, and striking the tilting cylinder 3. After the cam 6 rotates to its initial position, the elastic force of the spring 10 drives the striking plate 9 back to its initial position. This process is repeated. Then, the first motor 18 can be started, driving the movable plate 19 to rotate, and simultaneously driving the connecting rod 20 to move forward. The deflection of the filter plate 15 allows it to reciprocate inside the feed hopper 13. The spices can then be poured into the feed hopper 13 and fall into the filter plate 15 for sieving. Smaller impurities can fall through the discharge pipe 16. The spices then enter the rotating drum 3 through the feed pipe 14 and undergo multi-stage filtration through several filter holes 4 as the rotating drum 3 rotates. During filtration, the reciprocating tapping of the rotating drum 3 not only increases the spice feeding rate but also prevents the filter holes 4 from becoming clogged.
