Description

Technical Field

[0001] The utility model belongs to the technical field of seafood juice concentration, and particularly relates to a seafood juice concentration device. Background Art

[0002] A seafood juice concentration device, usually also known as an evaporator or concentrator, the main working principle of the seafood juice concentration device is to heat the seafood juice to evaporate the water inside it into water vapor, and then remove the water vapor from the system through processes such as condensation, so as to achieve the purpose of separating the water in the seafood juice and concentrating the seafood juice. This concentration process not only improves the concentration and taste of the seafood juice, but also retains its rich flavor and nutritional components.

[0003] Traditional seafood juice concentration devices generally rely on a stirring shaft to drive the seafood juice (raw material) to do a chaotic flow circulation mode, aiming to improve the evaporation speed of the raw material. However, the stirring shaft needs to consume additional mechanical energy, and large shear forces and impact forces will be generated during the stirring process, which will cause more or less damage to some components in the seafood juice. In addition, the stirring method also has more or less certain dead corners. When the raw material adheres to the heating area or surface for a long time, the retained raw material has the risk of scaling. At the same time, the stirring method is very susceptible to factors such as the viscosity and concentration of the raw material.

[0004] Therefore, it is very necessary to invent a seafood juice concentration device. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a seafood juice concentration device, including an evaporation and concentration main kettle. The evaporation and concentration main kettle and the evaporation and concentration circulation kettle are arranged on one side of each other, and the two are connected to each other through a circulation pump and a communication pipeline. The evaporation and concentration main kettle includes a kettle body, a partition plate, a manifold group, a cavity, a circulation pipe orifice and a spraying part. Three partition plates are fixedly installed in the hollow cavity of the kettle body and are distributed vertically. Manifold groups are installed on all three partition plates. Two circulation pipe orifices are integrally arranged on the kettle body. A spraying part is installed on one of the circulation pipe orifices. The cavity of the kettle body is connected to the evaporation and concentration circulation kettle through the circulation pipe orifice, two circulation pumps and a communication pipeline.

[0006] Preferably, steam collection pipes and concentrated discharge orifices are integrally arranged on both the kettle body and the evaporation and concentration circulation kettle. Above the kettle body, two steam heating orifices for inlet and outlet, a main steam collection pipeline and a raw material injection orifice are respectively arranged. The orifices arranged on the kettle body are all communicated with the cavity inside the kettle body.

[0007] Preferably, the cavity inside the kettle body is divided into four cavities with different regions by the three partition plates, which are, from top to bottom, the raw material inlet cavity, the raw material and steam integration cavity, the steam heating cavity, and the raw material retention cavity. Among them, the raw material inlet cavity communicates with the main steam collection pipeline and the raw material injection nozzle arranged on the kettle body. The raw material and steam integration cavity communicates with the two steam heating nozzles for inlet and outlet. And the raw material retention cavity communicates with the concentration discharge nozzle.

[0008] Preferably, the raw material and steam integration cavity in the cavity communicates with the steam collection pipe arranged on the kettle body for collecting the steam in this area. Among them, the two circulation nozzles arranged on the kettle body communicate with the raw material retention cavity and the raw material and steam integration cavity respectively. The two are connected to the inside of the evaporation and concentration circulation kettle through two circulation pumps and a connecting pipeline. The circulation pump is used to pump the raw material in the cavity of the kettle body into the evaporation and concentration circulation kettle, or to pump the raw material from the evaporation and concentration circulation kettle back into the cavity.

[0009] Preferably, the manifold group installed on the uppermost partition plate is used to connect the raw material inlet cavity and the raw material and steam integration cavity in the cavity together. The manifold groups installed on the other two partition plates are used to connect the raw material and steam integration cavity and the raw material retention cavity in the cavity together. Among them, the steam heating cavity is a completely sealed area, independent of the other three area cavities and not connected to the other three area cavities.

[0010] Preferably, there are two sets of the manifold groups in total. The manifold group is composed of several seamless metal pipes with hollow cavities. The manifold group is in a serpentine or linear pipe structure, and its cross-section is circular, square or polygonal. One of the sets of the manifold groups is located in the steam heating cavity.

[0011] Preferably, a spraying part is installed on the circulation nozzle communicating with the raw material and steam integration cavity in the cavity. The spraying part is used to inject the raw material into the raw material and steam integration cavity in a way of atomized spraying or low temperature and low pressure.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The seafood juice concentration device of the present utility model adopting a flow circulation mode shows substantial advantages in many aspects compared with the traditional stirring mode, greatly improving the production efficiency and product quality. Through the precisely designed flow path, the seafood juice realizes continuous and uniform circulating flow in the evaporation kettle, ensuring that the steam can fully and evenly heat every drop of the raw material, effectively avoiding the quality problems that may be caused by local overheating or uneven temperature, thereby improving the evaporation efficiency and ensuring the uniformity of the final product.

[0014] In addition, the flow circulation method significantly reduces the residence time of the raw materials on the heating surface, reduces the risk of fouling, and maintains high thermal transfer efficiency. The independent sealing design of the steam heating chamber and the optimized layout of the partition plate and the manifold group jointly promote the full contact between the steam and the seafood juice, further improving the utilization rate of thermal energy, making the concentration process more energy-efficient, and the flow circulation method can better adapt to the processing requirements of different types and concentrations of seafood juice.

[0015] From the perspective of energy consumption, the flow circulation method significantly reduces the mechanical energy consumption compared with the stirring method. It mainly relies on the power of the pump to drive the raw material circulation, rather than consuming a large amount of energy on the operation of the stirrer, thus achieving effective energy savings. At the same time, this method avoids the damage to the components of the seafood juice caused by the shear force and impact force that may occur during the stirring process, better protects the integrity and flavor of the raw materials, and ensures the high quality of the final product.

[0023] As shown in the Figure 1 to Figure 3 drawings: A seafood juice concentration device provided by the present invention includes an evaporation and concentration main kettle 1. The evaporation and concentration main kettle 1 and the evaporation and concentration circulation kettle 2 are arranged on one side of each other, and they are interconnected through a circulation pump 3 and a communication pipeline 4. Among them, the evaporation and concentration main kettle 1 includes a kettle body 11, a partition plate 12, a manifold group 13, a cavity 14, a circulation pipe orifice 15, and a spraying member 16. Three partition plates 12 are fixedly installed in the hollow cavity 14 of the kettle body 11 and are vertically distributed. Among them, manifold groups 13 are installed on all three partition plates 12. Two circulation pipe orifices 15 are integrally provided on the kettle body 11, and a spraying member 16 is installed on one of the circulation pipe orifices 15. The cavity 14 of the kettle body 11 is communicated with the evaporation and concentration circulation kettle 2 through the circulation pipe orifice 15, two circulation pumps 3, and a communication pipeline 4.

[0024] Furthermore, steam collection pipes 5 and concentrated discharge nozzles 6 are integrally provided on both the kettle body 11 and the evaporation and concentration circulation kettle 2. Above the kettle body 11, there are respectively provided two steam heating nozzles 7 for inlet and outlet, a main steam collection pipe 8, and a raw material injection nozzle 9. All the nozzles provided on the kettle body 11 communicate with the cavity 14 inside the kettle body 11. The steam collection pipe 5 is located at the top of the kettle body 11, which can effectively collect the steam generated during the evaporation process and avoid energy loss caused by steam escape. At the same time, the setting of the main steam collection pipe 8 further ensures that the steam can be centrally collected and directed to the subsequent treatment system. The concentrated discharge nozzle 6 is located at the bottom of the kettle body, which is convenient for quickly discharging the high-concentration seafood juice after the concentration process is completed, reducing the residence time of the product and ensuring the freshness and quality of the product.

[0025] Furthermore, the interior of the cavity 14 is carefully divided into four functional areas by three partition plates 12, which are, from top to bottom: a raw material inlet cavity, a raw material and steam integration cavity, a steam heating cavity, and a raw material retention cavity. The raw material inlet cavity, as the initial area, receives the fresh seafood juice injected from the raw material injection nozzle 9 and is connected to the main steam collection pipe 8, providing a channel for the preliminary collection of steam. The raw material and steam integration cavity is connected to the steam source through the steam heating nozzle 7 to achieve the full mixing and heating of the seafood juice and steam. The steam heating cavity, as a completely sealed independent area, ensures the efficient utilization of steam and the maximum transfer of heat energy. The raw material retention cavity is located at the bottom and is responsible for collecting and discharging the concentrated seafood juice, which is finally discharged through the concentrated discharge nozzle 6.

[0026] Furthermore, in order to achieve the efficient circulation of the seafood juice between the kettle body 11 and the evaporation and concentration circulation kettle 2, the device is specially designed with two circulation nozzles 15, which are respectively connected to the raw material retention cavity and the raw material and steam integration cavity. These two circulation nozzles 15 are connected to the inside of the evaporation and concentration circulation kettle 2 through two circulation pumps 3 and a connecting pipe 4 to form a complete circulation system. The start and stop of the circulation pump 3 can be flexibly controlled. According to the actual needs of the evaporation process, the raw materials in the kettle body 11 can be pumped into the evaporation and concentration circulation kettle 2 for further treatment, or the treated raw materials can be pumped back into the kettle body 11, realizing the recycling of raw materials and the maximization of evaporation efficiency.

[0027] Furthermore, the manifold group 13, as an important component connecting each cavity, is designed with precision and efficiency. The uppermost manifold group 13 connects the raw material inlet cavity and the raw material and steam integration cavity, ensuring that fresh raw materials can smoothly enter the evaporation area. The other two manifold groups 13 are responsible for connecting the raw material and steam integration cavity and the raw material retention cavity, enabling the smooth flow of raw materials during the evaporation process. The manifold group 13 is made of seamless metal pipes and has excellent properties such as corrosion resistance and high temperature resistance. Its serpentine or linear pipe structure and circular, square or polygonal cross-sectional design not only improve the uniformity of raw material flow but also enhance the heat transfer efficiency. Notably, a set of manifold group 13 is ingeniously arranged in the steam heating cavity, further improving the heat exchange efficiency in this area.

[0028] Furthermore, to improve the efficiency and effectiveness of raw material injection, a spray member 16 is particularly installed on the circulation pipe opening 15 communicating with the raw material and steam integration cavity. The spray member 16 has a conical pipe orifice structure and directly injects the raw materials into the raw material and steam integration cavity. Embodiment 2:

[0029] As shown in the Figure 2 or Figure 3 accompanying drawings: The difference between this embodiment and Embodiment 1 is that the spray member 16 is an atomizing nozzle, which uses the principle of high-speed spraying to directly inject the raw materials into the raw material and steam integration cavity in the form of atomization or fine streams. This method not only increases the contact area between the raw materials and the steam, improves the evaporation efficiency, but also helps to reduce the splashing and waste of raw materials during the injection process.

[0030] Other structures are the same as those in Embodiment 1 and will not be elaborated here. Embodiment 3:

[0031] As shown in the Figure 2 or Figure 3 accompanying drawings: The difference between this embodiment and Embodiment 1 is that the spray member 16 is an expansion valve, which can accurately adjust the flow rate and pressure of the raw materials according to the system requirements. As the expansion valve opens, the raw materials, under the action of an appropriate pressure difference, slowly and evenly pass through the expansion valve and enter the raw material and steam integration cavity in a more dispersed and delicate state.

[0032] In this process, the expansion valve plays a role similar to "throttling". It not only restricts the flow rate of the raw materials but also causes the raw materials to undergo slight expansion and dispersion when passing through the valve orifice, increasing the contact area between the raw materials and the subsequent steam. In this way, the raw materials can be more fully mixed with the steam in the raw material and steam integration cavity, accelerating the evaporation process and improving the concentration efficiency.

[0033] Meanwhile, due to the regulating effect of the expansion valve, the injection process of the raw materials becomes more stable and controllable, avoiding problems such as raw material splashing, waste, or system pressure fluctuations caused by too fast flow rate or unstable pressure. This not only ensures the continuity and stability of the evaporation process but also helps to extend the service life of the equipment and reduce maintenance costs.

[0034] The other structures are the same as those in Embodiment 1 and will not be described in detail here.

[0035] Working principle:

[0036] First, fresh seafood juice is injected into the raw material inlet chamber of the evaporation and concentration main kettle 1 through the raw material injection pipe orifice 9. The raw material inlet chamber serves as the initial area, receiving and temporarily storing these raw materials to prepare for the subsequent evaporation process.

[0037] Then, with the start of the evaporation process, steam enters the steam heating chamber through the steam heating pipe orifice 7. The steam heating chamber, as a completely sealed independent area, provides a stable heat source for the entire evaporation process. The steam is heated in the steam heating chamber and converted into high-temperature steam, and then enters the raw material and steam integration chamber under the guidance of the manifold group 13.

[0038] In the raw material and steam integration chamber, the high-temperature steam is fully mixed with the seafood juice raw materials to form a mixture of steam and liquid. At this time, the ejector 16 (conical pipe orifice structure) starts to work, and it injects the raw materials into the raw material and steam integration chamber in the form of atomization or low-temperature and low-pressure injection, further promoting the mixing and contact of the raw materials and steam and accelerating the evaporation process.

[0039] As the evaporation progresses, the moisture in the seafood juice gradually evaporates and the concentration gradually increases. The preliminarily concentrated seafood juice then flows into the raw material retention chamber under the guidance of the manifold group 13. The raw material retention chamber is located at the bottom and is responsible for collecting and temporarily storing these preliminarily concentrated seafood juices.

[0040] To achieve further concentration and recycling of the seafood juice, the device is specially designed with two circulation pipe orifices 15 and two circulation pumps 3. When further concentration is required, the circulation pump 3 is started, and the seafood juice in the raw material retention chamber is pumped into the evaporation and concentration circulation kettle 2 through the connecting pipe 4. In the evaporation and concentration circulation kettle 2, the seafood juice continues to be heated and evaporated by the steam to achieve further concentration.

[0041] Finally, when the seafood juice reaches the required concentration, it is quickly discharged through the concentrated discharge pipe orifice 6 at the bottom of the evaporation and concentration circulation kettle 2, collected and stored. At the same time, the steam generated during the evaporation process is collected through the steam collection pipe 5 and the steam collection main pipe 8, and can be directed to the subsequent treatment system or used for other purposes, avoiding energy loss caused by steam escape.

[0042] In summary: Through the collaborative work of components such as the main evaporation and concentration kettle 1, the evaporation and concentration circulation kettle 2, the circulation pump 3, the connecting pipeline 4, and the manifold group 13, the high-efficient evaporation and concentration of seafood juice are achieved, while ensuring the product quality and production efficiency.

[0043] Any technical solution that uses the technical solution described in the present utility model, or is designed by those skilled in the art inspired by the technical solution of the present utility model and achieves the above technical effects, shall fall within the protection scope of the present utility model.
