Description

Technical Field

[0001] The invention relates to the technical field of flavoring agent preparation, and in particular to a method for preparing a flavoring agent using an ultrasonic auxiliary device. Background Art

[0002] Flavor enhancers are food additives that can significantly increase the original flavor of food, beverages, and alcoholic beverages, especially the fragrance and sweetness. Flavor enhancers are usually used in very small amounts and have significant flavor enhancement effects, and can be added directly to food. When artificial flavors cannot completely simulate natural flavors, they are used to enhance the original flavor of food and improve the flavor of synthetic flavors and spices, thereby improving product quality and meeting consumers' life needs.

[0003] At present, when producing flavor enhancers, it is necessary to first prepare and proportion the raw materials. After completion, the proportioned raw materials are stirred to make them fully mixed and form a relatively viscous intermediate. Finally, the intermediate is concentrated.

[0004] In the production process of flavor enhancers, stirring is a key step to ensure uniform mixing of raw materials and improve product quality. However, traditional axial rotation stirring technology faces the dual challenges of efficiency bottleneck and volatile component control. On the one hand, a single stirring method is difficult to fully mix viscous or high-density raw materials, resulting in low production efficiency; on the other hand, in order to avoid excessive evaporation of volatile components and overheating of equipment under high-speed stirring, the stirring speed is strictly limited, which further restricts the improvement of stirring efficiency; in summary, when the stirring method is single and the stirring rate is limited, the existing technology is difficult to meet the needs of efficient production.

[0044] A method for preparing a flavoring agent using an ultrasonic assisted device comprises the following steps:

[0045] Step 1: Add the raw materials required for preparing the flavor enhancer into the reaction tank 2 in sequence, wherein the raw materials are specifically 80-90% ethyl maltol, 5-10% furanone, and 0.5-1% methylcyclopentenolone;

[0046] Step 2: adding clean water to make the solid-liquid mass ratio of the material be 1:2-3, and using a low-temperature stirring component to perform low-temperature stirring treatment on the raw materials inside the reaction tank 2;

[0048] Step 4: lower the height of the reaction tank 2 and discharge the materials.

[0049] As a further solution of the present invention, the top end of the end cavity ring block 902 is fixedly connected to the mother tube 804, and the top end of the mother tube 804 is rotatably installed with the end tube 8, one side of the outer peripheral wall of the end tube 8 is fixedly connected to a limiting guide rod 801, and the end of the limiting guide rod 801 is slidably connected to the top end of the supporting frame 1; the setting of the limiting guide rod 801 can prevent the end tube 8 from rotating, and at the same time, enable the end tube 8 to move up and down following the mother tube 804.

[0050] Furthermore, one side of the end tube 8 is fixedly connected to a liquid inlet pipe 803, and the top of the end tube 8 is fixedly connected to a liquid outlet pipe 802. The ends of the liquid inlet pipe 803 and the liquid outlet pipe 802 are fixedly connected to an external circulating cooling water system through a corrugated hose. The provided corrugated hose can prevent the liquid inlet pipe 803 and the liquid outlet pipe 802 from interfering with the external circulating cooling water system when they move vertically.

[0051] Through the above structure, the external circulating cooling water system can input low-temperature water into the end tube 8 and the main pipe 804 through the liquid inlet pipe 803.

[0052] As a further solution of the present invention, a bucket-shaped end 14 is fixedly installed on one end of the inner wall of the mother tube 804, and a folded water-cooling cavity 305 is opened inside each of the plurality of stirring vertical plates 304. One ends of the plurality of folded water-cooling cavities 305 are fixedly connected to a liquid infusion tube 10, and one end of the liquid infusion tube 10 is fixedly passed through the bucket-shaped end 14 and is rotatably connected to the liquid outlet tube 802.

[0053] Furthermore, the bottom of the bucket-shaped end 14 is fixedly connected to a plurality of equally spaced infusion tubes 11, and the other end of the infusion tube 11 is fixedly connected to the end of the folded water-cooling cavity 305, and a drive motor 9 is fixedly installed on the mounting end 302, and the output shaft of the drive motor 9 and the end cavity ring block 902 are jointly sleeved with a transmission belt 901; through the above structure, the water-cooling liquid enters the mother tube 804 and is input into each folded water-cooling cavity 305 through the infusion tube 11, thereby making the stirring vertical plate 304 in a low temperature state; after passing through the folded water-cooling cavity 305, the water-cooling liquid exchanges heat with the stirring vertical plate 304, and after the heat exchange is completed, the water-cooling liquid flows out through the infusion tube 10, thereby completing the circulation treatment of the water-cooling liquid.

[0054] As a further solution of the present invention, the scraper assembly includes a reciprocating screw 4 rotatably mounted on a rotating end plate 303, a mounting block 501 is fixed on the rotating end plate 303, and a horizontal axis 5 is rotatably mounted on the mounting block 501, one end of the horizontal axis 5 and the top of the reciprocating screw 4 are fixedly mounted with mutually meshing transmission conical teeth 503, the other end of the horizontal axis 5 is fixedly mounted with a gear 502, a gear ring 301 is fixedly mounted on the mounting end 302, and the gear 502 and the gear ring 301 are meshed with each other.

[0055] Through the above structure, by means of the transmission belt 901, the driving motor 9 can drive the end cavity ring block 902 to rotate. In this process, the horizontal axis 5 can rotate along the gear ring 301. After the mutual cooperation of the gear 502 and the gear ring 301, the horizontal axis 5 can rotate, and then after the transmission action of the transmission conical tooth 503, the reciprocating screw 4 can be driven to rotate. At the same time, the rotation directions of the reciprocating screw 4 and the rotating end plate 303 are opposite; the rotation directions of the reciprocating screw 4 and the multiple stirring vertical plates 304 are also opposite.

[0056] As a further solution of the present invention, a corresponding reciprocating sleeve 7 is installed on the reciprocating screw 4, and a plurality of equally spaced end rods 701 are fixedly connected to the outer peripheral wall of the reciprocating sleeve 7, a scraper frame 703 is fixedly installed at the end of each end rod 701, and the scraper frame 703 is slidably connected to the outer wall of the stirring vertical plate 304, and a plurality of equally spaced stirring blades 401 are fixedly connected to the bottom end of the reciprocating screw 4.

[0057] Furthermore, a pair of hydraulic rods 101 are fixedly installed on the top of the support frame 1, and the extension rod ends of the pair of hydraulic rods 101 are fixedly connected to the surface of the sealed cover 3, the ultrasonic auxiliary component includes an annular groove frame 601, and the upper surface of the annular groove frame 601 is fixedly connected to the bottom ends of multiple sliding rods 6, and the lower surface of the annular groove frame 601 is fixedly installed with multiple equidistantly distributed small ultrasonic oscillators 602, annular rods 702 are rotatably installed inside the annular groove frame 601, and connecting rib rods 704 are fixed between the multiple annular rods 702 and the scraper frame 703, and a plurality of through openings 103 compatible with the sliding rods 6 are opened at the top of the support frame 1.

[0058] Through the above structure, the stirring vertical plate 304 can rotate along with the end cavity ring block 902 and the rotating end plate 303, and drive the reciprocating shaft sleeve 7 to rotate synchronously by means of the scraper frame 703 and the end rod 701. At this time, the rotation direction of the reciprocating shaft sleeve 7 is also opposite to that of the reciprocating screw 4, so that the reciprocating shaft sleeve 7 can move back and forth vertically along the reciprocating screw 4. At this time, the scraper frame 703 can scrape the outer wall of the stirring vertical plate 304 to remove attached impurities; on the other hand, the scraper frame 703 can also drive the annular rod 702 and the annular groove frame 601 to move vertically through the connecting rib rod 704, so that the small ultrasonic oscillator 602 on the bottom side of the annular groove frame 601 can fully contact with the material, thereby improving its auxiliary mixing effect on the material.

[0059] As a further solution of the present invention, the spray assembly includes a liquid outlet cavity 306 opened on a plurality of stirring vertical plates 304, and a plurality of spray branches 307 connected to the interior of the liquid outlet cavity 306 are opened on one side of the stirring vertical plates 304, the liquid outlet cavity 306 is fixedly connected to an L-shaped end tube 12, and the other end of the L-shaped end tube 12 is fixedly penetrated into the interior of an infusion tube 10, and a solenoid valve 13 is fixedly installed on the L-shaped end tube 12.

[0060] Through the above structure, when the stirring operation of the material is completed and the relevant parts need to be cleaned, multiple solenoid valves 13 can be controlled to open. Since the external circulating cooling water system can give the water-cooling liquid a faster flow rate, part of the water-cooling liquid passing through the folded water-cooling chamber 305 can enter the liquid outlet chamber 306 through the L-shaped end pipe 12, and maintain a certain pressure to be sprayed out through multiple spray branches 307, so that the reciprocating shaft sleeve 7 and the reciprocating screw 4 can be cleaned, thereby greatly reducing the subsequent cleaning and maintenance pressure.

[0061] Furthermore, the bottom end of the reaction tank 2 is a bucket-shaped structure, and a discharge valve 203 is fixedly installed at the bottom end of the reaction tank 2, an extension ring 202 is fixedly installed on the outer peripheral wall at one end of the reaction tank 2, and a pair of hydraulic rods 201 are fixedly installed between the bottom side of the extension ring 202 and the bottom of the support frame 1, a limiting slot plate 102 is fixedly installed on one side of the support frame 1, and one side of the extension ring 202 is slidably connected to the limiting slot plate 102.

[0062] Through the above structure, the hydraulic rod 201 is arranged to cooperate with the limiting slot plate 102 to stably adjust the height of the reaction tank 2, so as to facilitate the separation of the low-temperature stirring assembly from the reaction tank 2 more thoroughly, so as to facilitate subsequent cleaning and maintenance.

[0063] The specific working method is as follows: when actually used, the raw materials required for preparing the flavoring agent are first added into the reaction tank 2 in sequence. After completion, the hydraulic rod 101 and the hydraulic rod 201 are controlled to start, wherein the hydraulic rod 101 pushes the airtight cover 3 to move downward, and the hydraulic rod 201 pushes the reaction tank 2 to move upward stably until the airtight cover 3 is closed with the top of the reaction tank 2; the driving motor 9 is controlled to start, and the transmission belt 901 is used to drive the end cavity ring block 902, the plurality of stirring vertical plates 304 and the rotating end plate 303 to rotate; the stirring vertical plates 304 are used to stir the materials to promote the mixing process between the materials;

[0064] In this process, the external circulating cooling water system can input low-temperature water into the end tube 8 and the mother tube 804 through the liquid inlet pipe 803, and then enter the water-cooling liquid of the mother tube 804, and then enter each folded water-cooling cavity 305 through the infusion pipe 11, so that the stirring vertical plate 304 is in a low-temperature state; after passing through the folded water-cooling cavity 305, the water-cooling liquid exchanges heat with the stirring vertical plate 304. After the heat exchange is completed, the water-cooling liquid flows out through the infusion pipe 10, thereby completing the circulation treatment of the water-cooling liquid;

[0065] During the rotation of the rotating end plate 303, the horizontal shaft 5 rotates along the gear ring 301. The gear 502 and the gear ring 301 cooperate with each other to make the horizontal shaft 5 rotate. After the transmission of the transmission conical gear 503, the reciprocating screw 4 can be driven to rotate. At the same time, the rotation directions of the reciprocating screw 4 and the rotating end plate 303 are opposite; the rotation directions of the reciprocating screw 4 and the multiple stirring vertical plates 304 are also opposite; thereby, the reciprocating shaft sleeve 7 moves back and forth vertically along the reciprocating screw 4. At this time, the scraping frame 703 is provided to scrape the outer wall of the stirring vertical plate 304 to remove the attached impurities; on the other hand, the scraping frame 703 also drives the annular rod 702 and the annular groove frame 601 to move vertically through the connecting rib rod 704, so that the small ultrasonic oscillator 602 on the bottom side of the annular groove frame 601 is fully in contact with the material, thereby improving its auxiliary mixing effect on the material;

[0066] After the mixing operation of the material is completed, the unloading valve 203 can be opened to discharge the mixed material. When the relevant parts need to be cleaned, multiple solenoid valves 13 can be controlled to open. Since the external circulating cooling water system gives the water-cooling liquid a faster flow rate, part of the water-cooling liquid passing through the folded water-cooling chamber 305 can enter the liquid outlet chamber 306 through the L-shaped end pipe 12, and maintain a certain pressure to be sprayed out through multiple spray branches 307, thereby achieving the cleaning of the reciprocating shaft sleeve 7 and the reciprocating screw 4, thereby greatly reducing the subsequent cleaning and maintenance pressure.
