Description

Technical Field

[0002] As an indispensable component of the food industry, the production process of seasonings has a decisive influence on the flavor and quality of the product. In the production process of compound seasonings, concentration is a key step, which directly affects the flavor stability and preservation of the product.

[0003] The concentration of compound seasoning is often carried out by directly heating the raw materials so that the excess water in the compound seasoning is heated and evaporated. For example, Chinese utility model patent CN221310650U discloses a seasoning concentration reaction device, and specifically discloses that the reaction device includes a mounting frame, a reactor arranged in the mounting frame, the reactor includes a reactor body and a reactor cavity, a stirring assembly is arranged in the reactor cavity, the stirring assembly includes a motor and a stirring shaft, a stirring member 1 is arranged on the stirring shaft, a sealing member is arranged at the bottom end of the stirring shaft, a transmission shaft 1 is rotatably connected in the sealing member, a transmission shaft 3 is rotatably connected in the stirring member 1, a stirring member 2 perpendicular to the stirring direction of the stirring member 1 is arranged on the transmission shaft 3, when the seasoning is boiled, the stirring shaft is driven to rotate by the motor, the stirring shaft drives the stirring member 1 to rotate, the stirring shaft drives the transmission shaft 1 to rotate, and the stirring member 2 connected to it is indirectly driven to rotate through the transmission shaft 1, thereby improving the fusion speed between the seasonings, thereby improving the boiling quality of the seasoning and enriching the taste of the seasoning. Although it can achieve the mixing and concentration of compound seasonings, due to the complex variety and state of the raw materials, it is inevitable that the burning phenomenon will occur during the concentration process. This problem not only affects the flavor and quality of the product, but also may lead to waste of raw materials and reduced production efficiency. The occurrence of the burning phenomenon is usually caused by high temperature or insufficient stirring after the seasoning is concentrated to a certain degree, which is particularly common in traditional single-axis unidirectional stirring and direct heating concentration technology.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] Example 1: Please refer to Figures 1 to 7 As shown, a compound seasoning concentration reactor comprises: a frame 1 for supporting, a first concentration reactor 2 for initially concentrating the compound seasoning, a second concentration reactor 3 for re-concentrating the compound seasoning after the initial concentration, and a steam pressurizing mechanism 4 for pressurizing the water vapor generated by concentrating the first concentration reactor 2 and the second concentration reactor 3 and then heating the pure water in the steam heating chamber 33.

[0025] The first concentration reactor 2 includes an upper reactor body 21, an air guide cover 22, a lower reactor body 23 and a first stirring mechanism 24. The lower reactor body 23 is fixedly arranged on the frame 1, the upper reactor body 21 is fixedly arranged on the lower reactor body 23, and the lower reactor body 23 is provided with a first concentration chamber 231, a heat transfer oil chamber 232, a heating wire 233, a liquid collecting tank 234 and a connecting pipe 238.

The air guide cover 22 is fixedly connected to the guide groove 222 of the lower reactor body 23, and correspondingly, the guide groove 222 is arranged on the concave side of the air guide cover 22. It can be understood that the heating wire 233 heats the composite seasoning in the first concentration reactor 2 by heating the heat transfer oil, and can also use the waste heat to heat the condensed water in the first steam chamber 235. The water vapor generated by heating the composite seasoning in the first concentration chamber 231 enters the gap between the air guide hood 22 and the upper kettle body 21 through the steam hole 221 under the guidance of the air guide hood 22, and then enters the first air outlet pipe 212. The condensed water generated on the air guide hood 22 flows into the liquid collecting tank 234 along the guide groove 222.

[0026] Specifically, the lower kettle body 23 is also provided with a first steam chamber 235, a second steam chamber 236 and a second air outlet pipe 237.

At the same time, when a large amount of condensed water is generated, the condensed water cannot be completely evaporated into water vapor in the first steam chamber 235, and the condensed water that cannot be evaporated will enter the bottom of the second steam chamber 236. The bottom of the second steam chamber 236 is in contact with the heat transfer oil chamber 232, and this part of the condensed water can be gradually heated and evaporated into water vapor, and then the second steam chamber 236, the second air outlet pipe 237 and the pipeline synchronously enter the steam pressurizing mechanism 4.

The rotating shaft of the first driving motor 241 is fixedly connected to the stirring rod 242. It can be understood that the first driving motor 241 can drive the stirring rod 242 to rotate in the first concentration chamber 231. The stirring rod 242 stirs the compound seasoning, which can accelerate the evaporation of water and prevent the compound seasoning from being burnt.

[0029] The second concentration reactor 3 includes a second concentration chamber 31, a second stirring mechanism 32 and a steam heating chamber 33. The second concentration reactor 3 is fixedly mounted on the frame 1, and a third air outlet pipe 311 and a material outlet pipe 313 are provided on the second concentration chamber 31, and a first pressure relief valve 312 is also installed on the corresponding second concentration chamber 31. It can be understood that the steam pressurizing mechanism 4 can timely extract the water vapor generated in the second concentration chamber 31 through the pipeline and the third air outlet pipe 311, which can not only be used to heat the pure water in the steam heating chamber 33, but also timely extract the water vapor and part of the air, which can reduce the air pressure in the second concentration chamber 31, thereby accelerating the evaporation of water in the compound seasoning.

[0030] The connecting pipe 238 is connected to the second concentration chamber 31, and the second stirring mechanism 32 is installed in the second concentration chamber 31. Specifically, the second stirring mechanism 32 includes a second driving motor 321 and a stirring cage 322. The second driving motor 321 is fixedly installed on the second concentration reactor 3, and the stirring cage 322 is rotatably installed in the second concentration chamber 31. The rotating shaft of the second driving motor 321 is fixedly connected to the stirring cage 322. Correspondingly, the stirring cage 322 is provided with a feed hole 323 and a stirring paddle 324, and the feed hole 323 is provided below the connecting pipe 238. It can be understood that the compound seasoning after the initial concentration enters the second concentration chamber 31 through the connecting pipe 238, and then enters the stirring cage 322 through the feed hole 323 on the stirring cage 322, and then flows to the stirring paddle 324 under the action of gravity. The second drive motor 321 drives the stirring cage 322 to rotate, so that the compound seasoning can repeatedly flow in the second concentration chamber 31 under the stirring of the stirring paddle 324, which can increase the contact area between the compound seasoning and the air, further enhance the concentration effect, and prevent scorching.

[0031] The steam compression mechanism 4 is fixedly mounted on the frame 1 and is provided with an air inlet 41 and an air outlet 42.

Specifically, a spiral guide plate 333 is also arranged in the steam heating chamber 33, and it can be understood that after the water vapor is pressurized by the steam pressurizing mechanism 4, it enters the steam heating chamber 33 through the pipeline and the air inlet pipe 331, and the water vapor directly contacts the pure water, which can make the pure water quickly heated, and the pure water can heat the compound seasoning in the second concentration chamber 31. At the same time, the compound seasoning in the second concentration chamber 31 is heated by the pure water, which not only has a uniform temperature, but also does not cause the compound seasoning with a certain concentration in the second concentration chamber 31 to be burnt due to excessive temperature. The spiral guide plate 333 can enhance the mixing effect of water vapor and pure water, and the gas in the steam heating chamber 33 can be discharged from the device through the second pressure relief valve 332.

[0033] Embodiment 2: A production process based on the composite seasoning concentration reactor described in Embodiment 1, comprising the following steps: S1. Feeding: the compound seasoning is injected into the first concentration chamber 231 through the connecting pipe 238 .

[0035] S3, the second concentration reactor 3 is preheated, and the water vapor generated in the first concentration chamber 231 enters the gap between the air guide cover 22 and the upper kettle body 21 through the steam hole 221 under the guidance of the air guide cover 22, and then enters the first air outlet pipe 212, and the condensed water generated on the air guide cover 22 flows into the collecting tank 234 along the guide groove 222; the condensed water collected in the collecting tank 234 enters the first steam chamber 235, and the condensed water is heated in the first steam chamber 235, evaporated to generate water vapor, and the water vapor enters the steam pressurizing mechanism 4 through the first steam chamber 235, the second steam chamber 236, the second air outlet pipe 237 and the pipeline. At the same time, when the generated condensed water is large, the condensed water cannot be completely evaporated in the first steam chamber 235. The condensed water that fails to evaporate will enter the bottom of the second steam chamber 236. The bottom of the second steam chamber 236 is in contact with the heat transfer oil chamber 232, and the condensed water can be gradually heated and evaporated into water vapor. Then, the second steam chamber 236, the second air outlet pipe 237 and the pipeline enter the steam pressurizing mechanism 4 synchronously; the water vapor enters the steam pressurizing mechanism 4 through the second steam chamber 236, the second air outlet pipe 237 and the pipeline, and the steam pressurizing mechanism 4 pressurizes the water vapor and then enters the steam heating chamber 33 through the pipeline and the air inlet pipe 331 to heat the pure water, and preheat the second concentration chamber 31; the water vapor directly contacts the pure water, which can heat the pure water quickly, and the pure water can heat the compound seasoning in the second concentration chamber 31.

[0036] S4, re-concentration, the compound seasoning after the initial concentration enters the second concentration chamber 31 through the connecting pipe 238, and then enters the stirring cage 322 through the feed hole 323 on the stirring cage 322, and then flows to the stirring paddle 324 under the action of gravity. The second driving motor 321 drives the stirring cage 322 to rotate, so that the compound seasoning can be repeatedly flowed in the second concentration chamber 31 under the stirring of the stirring paddle 324, which can increase the contact area between the compound seasoning and the air, and further enhance the concentration effect. At the same time, the compound seasoning in the second concentration chamber 31 is heated by pure water, which not only has a uniform temperature, but also does not cause the compound seasoning with a certain concentration in the second concentration chamber 31 to be burnt due to excessive temperature. The spiral guide plate 333 can enhance the mixing effect of water vapor and pure water; the water in the compound seasoning is further evaporated, and the generated water vapor enters the steam pressurizing mechanism 4 through the third air outlet pipe 311 and the pipeline.
