Abstract

[0002] Opacifying flavor is a kind of food flavor, which is often used to increase the turbidity of beverages. Most of the existing osmotic flavors are directly processed by homogenization of emulsifiers, oil phase, weighting agents and other raw materials. This kind of osmotic flavor is easy to stratify and difficult to store for a long time.
[0003] Based on this, our company's technical personnel explored and tried to introduce fermentation methods to prepare opaque flavors, and achieved certain results; the opaque flavors prepared in this way not only have a longer shelf life, but also have a rich aroma, which can enhance the flavor of the beverage. However, when preparing opaque flavors in this way, the fermentation products need to be further processed: separate the fermentation products, remove the filter residue, and obtain the filtrate; crush the bacteria in the filtrate; add auxiliary materials to the filtrate and mix them. However, the existing equipment cannot complete these processes alone. These processes need to be completed by multiple devices in relay, and the materials need to be circulated multiple times during the processing, which is more troublesome; and the equipment has low integration and a large footprint.

[0048] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.
[0049] The following is combined with Figure 1 ~Attached Fig.12 Embodiments of the present invention are described in detail.
[0050] The embodiment of the present invention provides a processing device for opaque flavor. The processing device includes: a horizontal centrifugal cylinder 1 and a grinding cylinder 2, a spiral blade 3 and a spray pipe 4 arranged in the centrifugal cylinder 1, a first motor driving the centrifugal cylinder 1 to rotate, a second motor driving the grinding cylinder 2 to rotate, and a third motor driving the spiral blade 3 to rotate. It should be understood that the first motor can be connected to the centrifugal cylinder 1 through a transmission member such as a belt and a gear to drive the centrifugal cylinder 1 to rotate; the second motor and the third motor are the same. Grinding beads are usually placed in the grinding cylinder 2, and the grinding beads can be zirconium oxide, steel balls, glass beads or ceramic beads. The grinding cylinder 2 is generally rotatably mounted on the base through a bearing. The centrifugal cylinder 1 is rotatably connected to the grinding cylinder 2. It should be understood that the centrifugal cylinder 1 can be rotatably connected to the grinding cylinder 2 through a bearing. The centrifugal cylinder 1 includes: a separation section 5 located in the grinding cylinder 2, and a pass-through section 6 located outside the grinding cylinder 2. The separation section 5 is provided with a plurality of filter holes. The periphery of the pass-through section 6 is provided with a first discharge port 7, and a first valve 8 is adapted. The grinding cylinder 2 is provided with a second discharge port 9 on the circumferential side thereof, and is adapted with a second valve 10. It should be understood that the second discharge port 9 is usually equipped with a filter plate to prevent the grinding beads from being discharged from the second discharge port 9. The first end of the centrifugal cylinder 1 is rotatably connected to the first end cover 11, and the first end cover 11 is provided with a first feed port 12 and a first water inlet 13 connected to the spray pipe 4. It should be understood that the first end cover 11 usually remains stationary. In addition, an electric heating element can be provided in the grinding cylinder 2, and a temperature controller can be adapted, and the electric heating element can be powered by an electric brush; in this way, the filtrate can be heated immediately according to actual needs. In addition, a metal filter screen can be installed on the inner peripheral wall of the centrifugal cylinder 1, and a filter cloth or filter membrane can be laid between the metal filter screen and the centrifugal cylinder 1; the centrifugal cylinder 1 needs to have a certain strength, in which case, its filter hole cannot be set finer; by providing a filter cloth or filter membrane, filtering and separation can be performed with finer filter holes while ensuring the strength of the centrifugal cylinder 1. The metal filter screen and filter cloth or filter membrane can be set in the whole section of the centrifugal cylinder 1. In this case, the metal filter screen and filter cloth or filter membrane need to be provided with a notch at the position of the first discharge port 7. The metal filter screen and filter cloth or filter membrane can also be set only in the separation section 5 of the centrifugal cylinder 1. In this case, the inner diameter of the separation section 5 needs to be slightly larger than the inner diameter of the outlet section 6 to ensure that the inner circumferential wall of the metal filter screen is flush with the inner circumferential wall of the outlet section 6, thereby ensuring that the spiral blade 3 can work normally.
[0051] The specific implementation mode of the present invention is described below: the fermentation product is fed into the centrifugal drum 1 through the first feed port 12. After preliminary draining, the first motor is driven to rotate the centrifugal drum 1, so that the filtrate can be thrown into the grinding drum 2, and the filter residue can be retained in the centrifugal drum 1; after the initial centrifugation is completed, the third motor can also drive the spiral blades 3 to rotate forward and reverse alternately to push the filter residue back and forth, and water is supplied to the spray pipe 4 to rinse the filter residue, and then centrifugation is performed again; according to the actual needs, multiple rinses and multiple centrifugations can be performed; after the separation of the fermentation product is completed, the first valve 8 is opened, and the spiral blades 3 are driven to push the filter residue to the first discharge port 7, so that the filter residue in the centrifugal drum 1 can be discharged. Next, the auxiliary material is fed into the first feed port 12, and water is supplied to the spray pipe 4 to rinse the centrifugal drum 1, so that the auxiliary material falls into the grinding drum 2; the second motor drives the grinding drum 2 to rotate, and the grinding drum 2 is provided with grinding beads, which will crush the bacteria in the filtrate and promote the mixing of the auxiliary material and various substances in the filtrate; after homogenization, the second valve 10 is opened, and the obtained milky flavor can be discharged from the second discharge port 9. The present invention can realize the solid-liquid separation of the fermentation substrate, the crushing of the bacteria, and the homogenization of the filtrate and the auxiliary material, so as to directly make the fermentation product into the milky flavor without the need for multiple circulation of materials, thereby improving the equipment integration and reducing the floor space.
[0052] Further, the first feed port 12 is connected to the bottom of the hopper 14, and the top of the hopper 14 is provided with a top cover 15; the side wall of the hopper 14 is provided with a second feed port 16 and a second water inlet 17; the first water inlet 13 and the second water inlet 17 are connected to the main water inlet 18; the first water inlet 13 is adapted to control the third valve 19 for opening and closing, the second water inlet 17 is adapted to control the fourth valve 20 for opening and closing, the first feed port 12 is adapted to control the fifth valve 21 for opening and closing, and the second feed port 16 is adapted to control the sixth valve 22 for opening and closing. It should be understood that the second feed port 16 is usually connected to the fermentation tank, and the fermentation product in the fermentation tank is in a slurry state. The sixth valve 22 and the fifth valve 21 are opened to allow the fermentation product to enter the centrifugal cylinder 1 through the hopper 14; in addition, according to actual conditions, a pump for sending the fermentation product to the hopper 14 can also be provided. Close the sixth valve 22, open the top cover 15 of the hopper 14, and then add the auxiliary material into the hopper 14. Close the top cover 15, open the fourth valve 20, and then rinse the hopper 14. Close the fourth valve 20, open the third valve 19, and then supply water to the spray pipe 4 to rinse the centrifugal cylinder 1.
[0053] Further, the hopper 14 is equipped with a stirring mechanism; the stirring mechanism includes: a bracket, a shaft 23 arranged at the top of the bracket, a scraper 24 arranged on the shaft 23, and a fourth motor 25 driving the shaft 23 to rotate; the bracket includes: a load ring 26 arranged at the bottom of the hopper 14, a load-carrying part 27 supporting the shaft 23, and a suspension beam 28 connecting the load ring 26 and the load-carrying part 27; a restricted head 29 is provided at the top of the shaft 23, and a limit groove is provided on the driving shaft of the fourth motor 25 to cooperate with the restricted head 29; a load groove 30 is provided at the top of the load-carrying part 27 to position the shaft 23; the scraper 24 contacts the inner wall of the hopper 14, and the fourth motor 25 is installed on the top cover 15. It should be understood that the stirring mechanism, in conjunction with the water flow rushing in from the second water inlet 17, can deliver the auxiliary material into the centrifugal cylinder 1 faster to prevent the auxiliary material from being blocked in the hopper 14. The caliber of the loading slot 30 can be matched with the diameter of the lower end of the shaft 23, and the lower end of the shaft 23 can be directly placed in the loading slot 30, so that the shaft 23 can be easily taken in and out. Of course, in order to reduce wear and improve stability, the caliber of the loading slot 30 can also be made larger than the diameter of the shaft 23, and the lower end of the shaft 23 can be installed in the loading slot 30 through a bearing. The restricted head 29 and the limiting groove are set to be non-circular. When the top cover 15 is closed, the restricted head 29 at the upper end of the shaft 23 is limited in the limiting groove of the drive shaft of the fourth motor 25. When the fourth motor 25 is started, the shaft 23 can be driven to rotate; the size of the limiting groove is usually slightly larger than the size of the restricted head 29. The shaft 23 and the fourth motor 25 are configured as a detachable structure. When the top cover 15 is opened, the shaft 23 and the scraper 24 will not be taken out of the hopper 14, and the shaft 23 and the scraper 24 will remain in the hopper 14, thereby avoiding the situation where the shaft 23 and the scraper 24 are difficult to insert into the hopper 14 after the auxiliary materials are added into the hopper 14.
[0054] Further, the spiral blade 3 has a hollow shaft, which constitutes the spray pipe 4; the hollow shaft is provided with a plurality of radial through holes; the second end of the centrifugal cylinder 1 is rotatably connected to the second end cover 31; the first end of the hollow shaft is rotatably connected to the first end cover 11; the second end of the hollow shaft is closed and rotatably connected to the second end cover 31; the second end of the hollow shaft passes through the second end cover 31 to form a transmission connection with the third motor. It should be understood that the first end of the hollow shaft can be rotatably connected to the first water inlet 13 of the first end cover 11 through a bearing.
[0055] Further, the first valve 8 has a first channel 32 and a second channel 33; the first channel 32 is inclined downward from left to right, and has a third discharge port 34 at its lower end; the diameter of the third discharge port 34 is smaller than the inner diameter of the first channel 32; the upper section of the second channel 33 extends vertically, and the lower section is inclined downward from right to left; the upper end of the second channel 33 is connected to the first discharge port 7, and the lower end is connected to the right side of the lower section of the first channel 32; a valve core 35 is provided in the first channel 32; a spring 36 is provided in the upper section of the first channel 32 to drive the valve core 35 to reset downward, and close the lower end of the first channel 32 and the lower end of the second channel 33; a placement groove 39 for placing a magnet is provided in the upper section outside the first channel 32. It should be understood that when the centrifugal cylinder 1 stops rotating and the first discharge port 7 is located at the bottom of the centrifugal cylinder 1, placing a magnet in the placement groove 39 can attract the valve core 35 to move upward, thereby opening the first valve 8; the magnet can be a permanent magnet or an electromagnet. The first valve 8 with the aforementioned structure has the following advantages: on the one hand, the filter residue discharged from the first discharge port 7 will first slide down obliquely from right to left along the second channel 33, and then slide down obliquely from left to right along the first channel 32, without any horizontal section on the way, and is not prone to stagnation and blockage; on the other hand, when the centrifugal cylinder 1 rotates, the valve core 35 will be thrown toward the third discharge port 34 under the action of centrifugal force, so that leakage of the first valve 8 due to looseness of the valve core 35 and the like can be avoided, thereby preventing the fermentation substrate in the centrifugal cylinder 1 from being thrown out and causing workshop pollution, thereby improving the stability and reliability of the first valve 8.
[0056] Further, the first valve 8 comprises: a first valve body 37 and a second valve body 38 which are detachably connected; the upper section of the first channel 32 is arranged on the first valve body 37, and the lower section of the first channel 32 and the second channel 33 are arranged on the second valve body 38; the upper end of the first channel 32 is closed; and the placement groove 39 is arranged on the upper part of the first valve body 37. It should be understood that flanges can be arranged on the first valve body 37 and the second valve body 38, and the first valve body 37 and the second valve body 38 are connected by bolts.
[0057] Furthermore, a first sealing mechanism 40 is provided at the lower end of the valve core 35; the first sealing mechanism 40 comprises: a first mounting seat 41, a first elastic sealing member 42, and a first limiting member 43 which are arranged in sequence from top to bottom; the first elastic sealing member 42 is provided with annular grooves at the outer edge and the inner edge of the lower end surface to form a first limiting outer ring 44 and a first limiting inner ring 45; the lower end surface of the first mounting seat 41 is provided with a first ring portion, and the lower end surface of the first ring portion is provided with a first limiting ring 46; the first limiting ring 4 6 has an inner diameter smaller than that of the first ring portion, so as to form a first annular groove 47 for the first restricted outer ring 44 to be inserted into; the first stopper 43 cooperates with the first mounting seat 41 to clamp the first restricted inner ring 45; the lower end surface of the first elastic seal 42 exceeds the lower end surface of the first stopper ring 46 and the lower end surface of the first stopper 43, so as to cooperate with the inner end surface of the second valve body 38 at the third discharge port 34 to form a seal; the first stopper 43 and the first mounting seat 41 are detachably connected to the valve core 35 by bolts. It should be understood that the first sealing mechanism 40 is set as a detachable structure, and the first elastic seal 42 can be replaced separately later. The fermentation substrate is slightly sticky. The first restricted outer ring 44 of the first elastic seal 42 is limited by the first annular groove 47 of the first mounting seat 41, and the first restricted inner ring 45 of the first elastic seal 42 is clamped by the first mounting seat 41 and the first limiting member 43; this can prevent the first elastic seal 42 from loosening or deforming due to sticking and pulling when the first valve 8 is opened. Installing the first sealing mechanism 40 on the valve core 35 instead of on the second valve body 38 is not only more convenient for disassembly and assembly; and when the first valve 8 is opened and a hose or nozzle is pulled to flush the first channel 32, the first sealing mechanism 40 can be flushed more cleanly. The first elastic seal 42 is usually made of elastic materials such as rubber or plastic, and a sealing ring is usually provided between the first mounting seat 41 and the valve core 35.
[0058] Furthermore, a second sealing mechanism 48 is provided at the upper end of the valve core 35; the second sealing mechanism 48 includes: a second mounting seat 49, a second elastic sealing member 50, and a second limiting member 51 which are arranged in sequence from top to bottom; the second elastic sealing member 50 is provided with annular grooves on the outer edge and the inner edge of the lower end surface respectively to form a second restricted outer ring and a second restricted inner ring; the lower end surface of the second mounting seat 49 is provided with a second ring portion, and the lower end surface of the second ring portion is provided with a second limiting ring; the inner diameter of the second limiting ring is smaller than the inner diameter of the second ring portion to form a second annular groove for the second restricted outer ring to be inserted into; the second limiting member 51 cooperates with the second mounting seat 49 to clamp the second restricted inner ring; the lower end surface of the second elastic sealing member 50 exceeds the lower end surface of the second limiting ring and the lower end surface of the second limiting member 51 to cooperate with the upper end surface of the second valve body 38 to form a seal; the second limiting member 51 and the second mounting seat 49 are detachably connected to the valve core 35 by bolts. It should be understood that the structure and principle of the second sealing mechanism 48 can be understood with reference to the first sealing mechanism 40 , and will not be described in detail here. The second valve 10 can adopt a structure similar to that of the first valve 8 .
